AMD Launches 3 Second-Gen Epyc Processors With 50% Lower Cost of Ownership (venturebeat.com) 36

Advanced Micro Devices said it is adding three new 2nd-Gen AMD Epyc server processors that can deliver up to 50% lower cost of ownership than rival Intel Xeon processors. From a report: The chips are part of AMD's attempt to grab technology leadership away from Intel, which has long dominated the server chip market. AMD has had an advantage lately with its high-performance Zen 2 cores designed to handle database, high-performance computing, and hyper-converged infrastructure workloads, Dan McNamara, senior vice president at AMD's server business unit, said in a press briefing. The three new processors are the AMD Epyc 7F32 (with 8 computing cores), Epyc 7F52 (16 cores) and EPYC 7F72 (24 cores). They have up to 500MHz of additional base frequency and large amounts of cache memory. AMD said the design gives Epyc the world's highest per-core performance x86 server central-processing unit. The previous chips in the second generation of Epyc processors debuted in the third quarter of 2019. [...] The 7F32 is priced at $2,100, the 7F52 at $3,100, and the 7F72 at $2,450.

What's New in Linux 5.6? WireGuard VPN and USB4 (msn.com) 33

Linux 5.6 "has a bit more changes than I'd like," Linus Torvalds posted on the kernel mailing list, "but they are mostly from davem's networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary..." TechRadar reports that the new changes include support for USB4 and GeForce RTX 2000 series graphics cards with the Nouveau driver: Yes, Turing GPU support has arrived with the open source Nouveau driver, along with the proprietary firmware images, as Phoronix.com reports. However, don't get too excited, as re-clocking doesn't work yet (getting the GPU to operate at stock clocks), and other important pieces of the puzzle are missing (like no Vulkan support with Nouveau). For the unfamiliar, Nouveau is an alternative to Nvidia's proprietary drivers on Linux, and although it remains in a relatively rough state in comparison, it's still good to see things progressing for Linux gamers with one of Nvidia's latest cards in their PC.

Linux 5.6 also introduces fresh elements on the AMD front, with better reset support for Navi and Renoir graphics cards (which helps the GPU recover if it hits a problem)... Another notable move is the introduction of WireGuard support, a newcomer VPN protocol which makes a potentially nifty alternative to OpenVPN.

Linux 5.6 also supports the Amazon Echo speaker, and naturally comes with a raft of other minor improvements...

Linus's post also notes that for the next release's timing they'll "play it by ear... It's not like the merge window is more important than your health, or the health of people around you." But he says he hasn't seen signs that the pandemic could affect its development (other than the possibility of distraction by the news).

"I suspect a lot of us work from home even normally, and my daughter laughed at me and called me a 'social distancing champ' the other day..."

Intel's 10th-gen H-series Laptop CPUs Reach 5.3GHz (engadget.com) 99

Just like Intel said at CES, it's crossed the 5GHz barrier with its new H-series 10th generation notebook CPUs. And you won't need to shell out for the top-of-the-line Core i9 to do it: The new six and eight-core i7 processors reach up to 5.1Ghz (boost speed) on a single core. From a report: But if you want to go all out, the octa-core i9-10980HK hits 5.3GHz -- and it's fully unlocked for overclocking, to boot. As usual, these H-series chips are meant for gaming and workhorse machines, not laptops where battery efficiency is key. You can expect around 44 percent better performance in Assassin's Creed Odyssey in 1080p with high settings, compared to the three-year-old Core i7-7700HQ.

And the new top-of-the-line Core i9 is 54 percent faster in Red Dead Redemption 2, compared to the i7-7820HK (there weren't any mobile Core i9 chips three years ago). Reaching beyond 5GHz is a notable achievement, and it's a nice deflect away from Intel's reliance on its 14nm "Comet Lake" architecture, just like its last batch of powerful ultraportable CPUs. Intel is competing directly with AMD's new 4000 series Ryzen mobile processors, which also offer up to eight cores, but with a lower 4.4GHz maximum clock speed. AMD is using a refined 7nm architecture, which makes them more efficient power-wise. And AMD's new chips also include up to 8 cores of Radeon Vega graphics, which can easily trounce Intel's aging UHD graphics. But really, all of these processors are best suited for notebooks with dedicated GPUs, so it makes sense for Intel to skimp on that for now.

A Hacker Stole and Leaked the Xbox Series X Graphics Source Code (engadget.com) 33

An anonymous reader quotes a report from Engadget: AMD has been having a particularly rough few months, apparently. The chip designer has revealed that a hacker stole test files for a "subset" of current and upcoming graphics hardware, some of which had been posted online before they were taken down. While AMD was shy on details, the claimed intruder told TorrentFreak that the material included source code for Navi 10 (think Radeon RX 5700 series), the future Navi 21 and the Arden GPU inside the Xbox Series X.

The self-proclaimed hacker added that she wanted $100 million for the source code and threatened to "leak everything" if there was no buyer. She reportedly found the GPU data in a "hacked computer" in November, although AMD said it hadn't been approached until December. AMD doesn't appear to be bowing under pressure. It believed the stolen code was "not core to the competitiveness or security" of its products, and said there was an "ongoing criminal investigation."

Microsoft Teases Revamped UI For Windows 10 (gizmodo.com) 160

In celebration of Windows 10 hitting 1 billion users, Microsoft's chief product officer Panos Panay teased Windows 10's next UI refresh. Gizmodo reports: In the video posted to Instagram, Microsoft starts by showing the evolution of its OS throughout the years going as far back as Windows 1.01 all the way to Windows 10. However, where things start to get interesting is around 12 seconds in when Microsoft shows off a new set of updated icons followed by a redesigned look for Windows 10's Start Menu and Live Tiles. Instead of a bunch of brightly color rectangles, Microsoft is implementing a more unified color scheme that can adjust automatically to match your desktop background and potentially other UI elements.

Additionally, Microsoft also showed off a wide variety of accessibility options including a range of pointers in various sizes and colors, what looks like improved support for the Xbox Adaptive Controller, a tease for a new built-in snipping tool, and more. Then Microsoft capped everything off by showing light and dark themes for Windows 10 along with a bunch of windows resizing and snapping options, all designed to making multi-tasking just a bit faster and easier. Microsoft also made a point to mention support for both x86-based systems powered by chips from Intel and AMD and ARM-based systems like the Surface Pro X.

The PlayStation 5 vs. the Xbox Series X: Which Is More Powerful? (engadget.com) 111

Now that Microsoft and Sony have published the technical specifications of their respective next-gen gaming consoles, we can compare them head-to-head to see which one has the edge. While Sony appears to lag behind Microsoft when it comes to specs, the PS5's speedy custom SSD may be its secret weapon. Engadget reports: Sony's lead PlayStation architect, Mark Cerny, finally gave us an in-depth look at the PS5 in a livestream event, in lieu of a major GDC keynote. [...] Cerny confirms that the PlayStation 5's graphics processor will feature 36 compute units and up to 10.28 teraflops worth of compute performance. That's a bit less than the Xbox Series X's 12-teraflop GPU, but realistically you might not see many differences in performance. There are plenty of other system optimizations, like the company's focus on a custom 825GB SSD, that'll be a huge leap over the PlayStation 4. That SSD will push 5.5 gigabytes per second compared to a mere 50 to 100 MB/s, meaning it can fill the system's 16GB of GDDR6 RAM in two seconds. And on the plus side, Sony will let you plug in a standard NVMe SSD to expand storage while Microsoft will rely on specialized 1TB SSD expansion cards.

Cerny was quick to point out that teraflop numbers are a "dangerous" way to measure absolute levels of performance. A teraflop from the PlayStation 5 translates to much more gaming performance than a teraflop from the PlayStation 4, thanks to the new console's more-efficient architecture. Still, it's not exactly unfair to compare the PS5 to the Xbox Series X, since both systems will be based on AMD's CPUs and GPUs. It's interesting to see how Sony and Microsoft devices take advantage of AMD's hardware. The PS5's eight-core Zen 2 CPU will run up to 3.5GHz with variable frequencies, so it can slow down when necessary. The Xbox Series X, meanwhile, will lock its Zen 2 processor at 3.8GHz, and devs can also choose to run their games at 3.6GHz with hyper threading. Sony also chose to use 36 RDNA 2 compute units running at up to 2.23GHz with a variable frequency while Microsoft stuffed its system with 52 compute units running at 1.825GHz. Cerny argues that running fewer cores at a higher frequency rate is more beneficial than running more cores at a lower rate, since it will lead to a speed bump across many GPU tasks.

Sony definitely has the lead with its custom SSD with 5GB/s of raw bandwidth and 8 to 9GB/s of compressed throughput. The Xbox Series X's SSD will be limited to 2.4GB/s of raw data and 4.8GB/s compressed. Again, while the numbers are significantly different, it's unclear how the performance will vary in real-world use. Microsoft also has a slightly higher GDDR6 memory bandwidth -- 10GB at 560GB/s and 6GB at 336GB/s -- than Sony's 448GB/s, which could make up for the slower storage.
As for backwards compatibility, Sony announced that the PlayStation 5 will support PS4 and PS4 Pro games, but the company made no mention of retro PS1, PS2, and PS3 titles. Microsoft, on the other hand, stated that the Xbox Series X will support all games playable on the Xbox One, including those Xbox 360 and original Xbox console titles currently supported through backwards compatibility on the Xbox One.

The PS5 Will Include PS4 Backwards Compatibility at Launch, But That's It (inputmag.com) 59

During today's PlayStation 5 livestream, Sony announced that the PlayStation 5 will be backwards compatible with PS4 and PS4 Pro games, but the company made no mention of retro PS1, PS2, and PS3 titles. From a report: Mark Cerny, Sony's lead system architect for PlayStation hardware, said the following about the PS5's backwards compatibility: "The PlayStation 5 GPU is backwards compatible with PlayStation 4. What does that mean? One way you can achieve backwards compatibility is to put the previous console's chips at in the new consoles like we did with some PlayStation 3s, but that's of course extremely expensive. A better way is to incorporate any differences in the previous console's logic into the new console's custom chips, meaning that even as the technology evolves, the logic and feature set that PlayStation 4 and PlayStation 4 Pro titles rely on is still available in backwards compatibility modes. One advantage of this strategy is that once backwards compatibility is in the console, it's in, and it's not as if a cost-down will remove backwards compatibility like it did on PlayStation 3. Achieving this unification of functionality took years of efforts by AMD, as any roadmap advancement creates a potential divergence in logic."

AMD Launches Ryzen 4000 Series Mobile CPUs With Major Performance Lift Claims (hothardware.com) 49

MojoKid writes: Though Ryzen 4000 Series laptop processors aren't available just yet, some of AMD's partners are going to begin taking pre-orders for notebooks soon. As such, AMD is lifting the veil on additional details and the architectural enhancements that make Ryzen 4000 Series AMD's strongest mobile processor line-up to date. AMD Ryzen 4000 series CPUs are based on the Zen 2 architecture, similar to the current Ryzen 3000 series desktop processors. AMD is touting an approximate 25% IPC increase versus Zen 1-based mobile parts, but there are additional benefits that boost performance and efficiency throughout the chips as well. These are monolithic SoCs, with up to 8-cores / 16-threads, that are manufactured on TSMC's 7nm node. AMD is claiming 20% lower SoC power, 2X the perf-per-watt, 5X faster state switching, and an approximate 3.4X improvement in relative power efficiency, in comparison to its mobile platform from 2015. AMD is claiming superior single-thread CPU performance versus current-generation Intel mobile processors and significantly better multi-threaded and graphics performance versus Intel, thanks to the increased core / thread counts and integrated Vega-based GPU of its Ryzen 4000 series. Battery life performance is claimed be strong as well, due to architectural enhancements for power optimization throughout the Ryzen 4000 design. AMD Ryzen 4000 Series laptops should be shipping in market sometime in the next month or so.

AMD Processors From 2011 To 2019 Vulnerable To Two New Attacks (zdnet.com) 71

An anonymous reader quotes a report from ZDNet: AMD processors manufactured between 2011 and 2019 (the time of testing) are vulnerable to two new attacks, research published this week has revealed (PDF). The two new attacks impact the security of the data processed inside the CPU and allow the theft of sensitive information or the downgrade of security features. The research team said it notified AMD of the two issues in August 2019, however, the company has not released microcode (CPU firmware) updates, claiming these "are not new speculation-based attacks," a statement that the research team disagrees with.

The two new attacks target a feature of AMD CPUs known as the L1D cache way predictor. Introduced in AMD processors in 2011 with the Bulldozer microarchitecture, the L1D cache way predictor is a performance-centric feature that reduces power consumption by improving the way the CPU handles cached data inside its memory. A high-level explanation is available below: "The predictor computes a uTag using an undocumented hash function on the virtual address. This uTag is used to look up the L1D cache way in a prediction table. Hence, the CPU has to compare the cache tag in only oneway instead of all possible ways, reducing the power consumption." The two new attacks were discovered after a team of six academics [...] reverse-engineered this "undocumented hashing function" that AMD processors were using to handle uTag entries inside the L1D cache way predictor mechanism. Knowing these functions, allowed the researchers to recreate a map of what was going on inside the L1D cache way predictor and probe if the mechanism was leaking data or clues about what that data may be.
While the attacks can be patched, AMD denies that these two new attacks are a concern, claiming they "are not new speculation-based attacks" and that they should be mitigated through previous patches for speculative execution side channel vulnerabilities.

The research team says AMD's response is "rather misleading," and that the attacks still work on fully-updated operating systems, firmware, and software even today.

AMD Discloses RDNA 2 Graphics, CDNA Data Center GPUs, Next-Gen Zen (hothardware.com) 20

"At its Financial Analyst Day, AMD disclosed additional details regarding its next generation CPU and GPU architectures," writes Slashdot reader MojoKid: - While the company isn't ready to disclose concrete details yet, AMD is promising that Navi 2X will arrive this year and deliver "enthusiast-class" performance, excellent power efficiency, and "top-of-stack" GPUs with "uncompromising 4K gaming".

- While AMD has RDNA for its gaming-centric consumer GPUs, the company is shifting to a new GPU compute architecture, dubbed CDNA, for its High-Performance Computing (HPC) and Machine Learning (ML) accelerators. CDNA has been designed from the ground-up for ML/HPC applications, and will leverage what AMD calls its second-generation Infinity Architecture interconnects.

- AMD also reiterated that its first Zen 3-based products will be rolling out later this year. On the server side, this means EPYC 7003 "Milan" processors, but the company also revealed that Zen 3 client processors would also arrive by the end of 2020.

Ampere Altra is the First 80-core ARM-based Server Processor (venturebeat.com) 64

Ampere has unveiled the industry's first 80-core ARM-based 64-bit server processor today in a bid to outdo Intel and Advanced Micro Devices in datacenter chips. From a report: Ampere announced today that it has begun providing samples of the Ampere Altra processor for modern cloud and edge computing datacenters. The Ampere Altra processor runs on 210 watts and is targeted at such server applications as data analytics, artificial intelligence, database, storage, telco stacks, edge computing, web hosting, and cloud-native applications. Intel dominates about 95.5% of the server chip market with its x86-based processors, and AMD has the rest. But Ampere is targeting power-efficient, high-performance, and high-memory capacity features. Renee James, former president of Intel and CEO of Ampere, said in an interview with VentureBeat that the chip is faster than a 64-core AMD Epyc processor and Intel's 28-core high-end Xeon "Cascade Lake" chip.

Stealth Startup Plans Fundamentally New Kind of Computer with Circuit-Rearranging Processor (zdnet.com) 107

VCs have given nearly half a billion dollars to a stealth startup called SambaNova Systems to build "a new kind of computer to replace the typical Von Neumann machines expressed in processors from Intel and AMD, and graphics chips from Nvidia."

ZDNet reports: The last thirty years in computing, said CEO Rodrigo Liang, have been "focused on instructions and operations, in terms of what you optimize for. The next five, to ten, to twenty years, large amounts of data and how it flows through a system is really what's going to drive performance." It's not just a novel computer chip, said Liang, rather, "we are focused on the complete system," he told ZDNet. "To really provide a fundamental shift in computing, you have to obviously provide a new piece of silicon at the core, but you have to build the entire system, to integrate across several layers of hardware and software...."

[One approach to training neural networks with very little labeled data] is part of the shift of computer programming from hard-coded to differentiable, in which code is learned on the fly, commonly referred to as "software 2.0." Liang's co-founders include Stanford professor Kunle Olukotun, who says a programmable logic device similar to a field-programmable gate array could change its shape over and over to align its circuitry [to] that differentiated program, with the help of a smart compiler such as Spatial. [Spatial is "a computing language that can take programs and de-compose them into operations that can be run in parallel, for the purpose of making chips that can be 'reconfigurable,' able to change their circuitry on the fly."]

In an interview in his office last spring, Olukotun laid out a sketch of how all that might come together. In what he refers to as a "data flow," the computing paradigm is turned inside-out. Rather than stuffing a program's instructions into a fixed set of logic gates permanently etched into the processor, the processor re-arranges its circuits, perhaps every clock cycle, to variably manipulate large amounts of data that "flows" through the chip.... Today's chips execute instructions in an instruction "pipeline" that is fixed, he observed, "whereas in this reconfigurable data-flow architecture, it's not instructions that are flowing down the pipeline, it's data that's flowing down the pipeline, and the instructions are the configuration of the hardware that exists in place.

Chasing AMD, Intel Promises Full Memory Encryption in Upcoming CPUs (arstechnica.com) 53

"Intel's security plans sound a lot like 'we're going to catch up to AMD,'" argues FOSS advocate and "mercenary sysadmin" Jim Salter at Ars Technica, citing a "present-and-future" presentation by Anil Rao and Scott Woodgate at Intel's Security Day that promised a future with Full Memory Encryption but began with Intel SGX (launched with the Skylake microarchitecture in 2015).

Salter describes SGX as "one of the first hardware encryption technologies designed to protect areas of memory from unauthorized users, up to and including the system administrators themselves." SGX is a set of x86_64 CPU instructions which allows a process to create an "enclave" within memory which is hardware encrypted. Data stored in the encrypted enclave is only decrypted within the CPU -- and even then, it is only decrypted at the request of instructions executed from within the enclave itself. As a result, even someone with root (system administrator) access to the running system can't usefully read or alter SGX-protected enclaves. This is intended to allow confidential, high-stakes data processing to be safely possible on shared systems -- such as cloud VM hosts. Enabling this kind of workload to move out of locally owned-and-operated data centers and into massive-scale public clouds allows for less expensive operation as well as potentially better uptime, scalability, and even lower power consumption.

Intel's SGX has several problems. The first and most obvious is that it is proprietary and vendor-specific -- if you design an application to utilize SGX to protect its memory, that application will only run on Intel processors... Finally, there are potentially severe performance impacts to utilization of SGX. IBM's Danny Harnik tested SGX performance fairly extensively in 2017, and he found that many common workloads could easily see a throughput decrease of 20 to 50 percent when executed inside SGX enclaves. Harnik's testing wasn't 100 percent perfect, as he himself made clear -- in particular, in some cases his compiler seemed to produce less-optimized code with SGX than it had without. Even if one decides to handwave those cases as "probably fixable," they serve to highlight an earlier complaint -- the need to carefully develop applications specifically for SGX use cases, not merely flip a hypothetical "yes, encrypt this please" switch....

After discussing real-world use of SGX, Rao moved on to future Intel technologies -- specifically, full-memory encryption. Intel refers to its version of full-memory encryption as TME (Total Memory Encryption) or MKTME (Multi-Key Total Memory Encryption). Unfortunately, those features are vaporware for the moment. Although Intel submitted an enormous Linux kernel patchset last May for enabling those features, there are still no real-world processors that offer them... This is probably a difficult time to give exciting presentations on Intel's security roadmap. Speculative prediction vulnerabilities have hurt Intel's processors considerably more than their competitors', and the company has been beaten significantly to market by faster, easier-to-use hardware memory encryption technologies as well. Rao and Woodgate put a brave face on things by talking up how SGX has been and is being used in Azure. But it seems apparent that the systemwide approach to memory encryption already implemented in AMD's Epyc CPUs -- and even in some of their desktop line -- will have a far greater lasting impact.

Intel's slides about their own upcoming full memory encryption are labeled "innovations," but they look a lot more like catching up to their already-established competition.

Intel Debuts 5G Server and Base Station Chips, Plus a PC Network Card (venturebeat.com) 8

Intel's sale of its consumer 5G modem unit signaled its exit from the smartphone business last year, but the company remains heavily committed to participating in the growing 5G marketplace -- primarily on the carrier and enterprise sides. Today, the company announced three chips built for various types of 5G computers, plus a 5G-optimized network adapter for PCs. From a report: Up first is an updated second-generation Xeon Scalable processor, now at a top speed of 3.9GHz and bolstered by additional AI capabilities to aid with inference applications. The new chip promises up to 36% more performance than the first-generation version, with up to 42% more performance per dollar, though early second-generation chips were introduced in April 2019. Intel says the Xeon Scalable is the "only CPU with AI built in" -- a pitch that's not exactly accurate, given the range of existing laptop and mobile CPUs with AI features, but one Intel further explains means "the only CPU on the market that features integrated deep learning acceleration." Xeon Scalable's Deep Learning Boost feature set promises up to 6 times more AI performance than AMD's Rome processors, though Intel won't quantify the number of TOPS available for AI processing, calling the metric "theoretical." Regardless, Intel says Xeon Scalable will support the cloud AI needs of Alibaba, AWS, Baidu, Microsoft, and Tencent, as well as other major companies.

Network-optimized "N-SKUs" of the new Xeon Scalable will also be available, offering up to 58% more performance for network function virtualization workloads compared with the first chip. Customers such as China Mobile, SK Telecom, Sprint, and T-Mobile Poland are all using Xeon Scalable in their 5G networks. The boosted Xeon Scalable chips are officially available starting today. Intel is also introducing the Atom P5900, billed as the first Intel architecture SoC for base stations and designed from the ground up for radio access network (RAN) needs. It's a 10-nanometer chip with hardware-based network acceleration features, including integrated packet processing, ultra low latency, and a switch for inline cryptographic acceleration.

Microsoft Reveals More Xbox Series X Specs (polygon.com) 49

Microsoft revealed new details on its next-generation console, text, on Monday morning, confirming specifications on what the company calls its "superior balance of power and speed" for its new hardware. From a report: The next-gen Xbox, Microsoft said, will be four times as powerful as the original Xbox One. The Xbox Series X "next-generation custom processor" will employ AMD's Zen 2 and RDNA 2 architecture, head of Xbox Phil Spencer wrote on the Xbox website. "Delivering four times the processing power of an Xbox One and enabling developers to leverage 12 [teraflops] of GPU (Graphics Processing Unit) performance -- twice that of an Xbox One X and more than eight times the original Xbox One," Spencer said. He called the next-generation Xbox's processing and graphics power "a true generational leap," offering higher frame rates -- with support for up to 120 fps -- and more sophisticated game worlds.

That 12 teraflops claim is twice that of what Microsoft promised with the Xbox One X (then known as Project Scorpio) when it revealed the mid-generation console update back in 2016. Spencer also outlined the Xbox Series X's variable rate shading, saying, "Rather than spending GPU cycles uniformly to every single pixel on the screen, they can prioritize individual effects on specific game characters or important environmental objects. This technique results in more stable frame rates and higher resolution, with no impact on the final image quality." He also promised hardware-accelerated DirectX ray tracing, with "true-to-life lighting, accurate reflections and realistic acoustics in real time." Microsoft also reconfirmed features like SSD storage, which promise faster loading times, as well as new ones, like Quick Resume, for Xbox Series X.

Intel's 'Clear Linux' Distro Beats Ubuntu and Windows 10 -- on an AMD Laptop (msn.com) 51

An anonymous reader quotes TechRadar: Intel's Clear Linux distribution looks like it could be the best operating system to run on cheap AMD hardware, with benchmarks showing it outperforms Windows 10 and Ubuntu on a $199 laptop with a budget AMD Ryzen 3200U processor. The Phoronix website ran a series of benchmarks on a super-cheap AMD laptop from Walmart, and found that Intel Clear Linux beat popular Linux distros Fedora and Ubuntu for 78% of the tests.

Not only is it remarkable that a relatively unknown Linux distro is so easily outperforming established operating systems, the fact that Intel is the company behind the distro is particularly ironic. As you can imagine, Clear Linux is optimized for Intel processors, but it seems like it works brilliantly on AMD hardware as well.

AMD Ryzen Threadripper 3990X 64-Core Chip Launched, Benchmarking a Beast CPU (hothardware.com) 99

MojoKid writes: In January at CES 2020 in Las Vegas, AMD CEO Dr. Lisa Su took to the stage during a press conference and revealed the company's forthcoming Ryzen Threadripper 3990X 64-core processor. Dr. Su disclosed the 3990X's speeds and feeds and showed the beastly chip taking down a pair of 28-core Xeons worth about $20K, in a 3D rendering benchmark, despite its much smaller price tag. Today, however, the company has lifted the veil on full details of the chip as well as its complete performance profile across a myriad of benchmarks, fresh off embargo lift. Thought it's packing 64 cores capable of processing 128 threads in SMT, the 3990X's TDP is still rated at 280W when it's configured at stock frequencies (2.9GHz base / 4.3GHz boost). As you might expect, Ryzen Threadripper 3990X was an absolute beast all of the multi-threaded tests that scale properly to leverage all of its cores. In fact, Threadripper 3990X stands head and shoulders above every other desktop processor on the market currently, besting competing many-core Intel solutions by more than 2X in some cases. However, because Threadripper 3990X has relatively high clocks for such a high core count chip, it also offers relatively strong performance for day-to-day use cases in lightly threaded workloads and gaming as well. There's no question, at $3990 MSRP, AMD's Threadripper 3990X isn't a mainstream desktop chip, but for those who need serious workstation performance and throughput, nothing on the desktop even comes close right now.

AMD Threadripper 3990X 64-Core Beast Spotted Outscoring Dual Intel Xeon Platinum (hothardware.com) 98

MojoKid writes: When AMD unveiled its forthcoming Ryzen Threadripper 3990X 64-core processor at CES 2020 this year, the company made no bones about comparing its performance to a many-core competitive platform from Intel. Under the hood of the yet formally released high-end workstation AMD chip are 64 physical cores capable of processing 128 threads in SMT, with a 2.9GHz base clock, 4.3GHz boost clock, and 256MB of L3 cache. All that horsepower resides in a single TRX40 socket with a 280 Watt TDP for a suggested retail price of $3990. Conversely, a dual socket Intel Xeon Scalable Platinum 8280 setup will sport 56 cores across two sockets with over a 400 Watt TDP that costs around $20,000. At CES, AMD showed its new 64-core Threadripper beating the dual Xeon Platinum setup in a 3D rendering application called VRAY, and today additional benchmark numbers have surfaced in SiSoft SANDRA, showing Threadripper 3990X out-scoring the Intel setup by around 18 percent. No doubt, AMD's Threadripper 3900X isn't a CPU for the average mainstream desktop user, but when the chips arrive to market in the near future, workstation and content creation professionals will likely be all over AMD's new 64-core beast chip.

Ubuntu vs Windows 10: Performance Tests on a Walmart Laptop (phoronix.com) 147

Phoronix's Michael Larabel is doing some performance testing on Walmart's $199 Motile-branded M141 laptop (which has an AMD Ryzen 3 3200U processor, Vega 3 graphics, 4GB of RAM, and a 14-inch 1080p display).

But first he compared the performance of its pre-installed Windows 10 OS against the forthcoming Ubuntu 20.04 LTS Linux distribution.

Some highlights: - Java text rendering performance did come out much faster on Ubuntu 20.04 with this Ryzen 3 3200U laptop...

- The GraphicsMagick imaging program tended to run much better on Linux, which we've seen on other systems in the past as well.

- Intel's Embree path-tracer was running faster on Ubuntu...

- Various video benchmarks were generally favoring Ubuntu for better performance though I wouldn't recommend much in the way of video encoding from such a low-end device...

- The GIMP image editing software was running much faster on Ubuntu 20.04 in its development state than GIMP 2.10 on Windows 10...

- Python 3 performance is still much faster on Linux than Windows.

- If planning to do any web/LAMP development from the budget laptop and testing PHP scripts locally, Ubuntu's PHP7 performance continues running much stronger than Windows 10. - Git also continues running much faster on Linux.

Their conclusion? "Out of 63 tests ran on both operating systems, Ubuntu 20.04 was the fastest... coming in front 60% of the time." (This sounds like 38 wins for Ubuntu versus 25 wins for Windows 10.)

"If taking the geometric mean of all 63 tests, the Motile $199 laptop with Ryzen 3 3200U was 15% faster on Ubuntu Linux over Windows 10."
