While many Gameworks VR features will be supported as far back as GeForce 6xx cards, the company's latest 'Maxwell' (9xx and Titan X) GPUs offer 'Multi-projection' which Reed says, 'enables us to very efficiently rasterize geometry into multiple viewports within a single render target at once... This better approximates the shading rate of the warped image that will eventually be displayed—in other words, it avoids rendering a ton of extra pixels that weren't going to make it to the display anyway, and gives you a substantial performance boost for no perceptible reduction in image quality.'
nateman1352 links to an article at Tom's Hardware which makes the interesting point that chip-maker AMD will offer Intel -- rather than AMD -- CPUs in their upcoming high-end gaming PC. (High-end for being based on integrated components, at least.) From the article: Recently, AMD showed off its plans for its Fiji based graphics products, among which was Project Quantum – a small form factor PC that packs not one, but two Fiji graphics processors. Since the announcement, KitGuru picked up on something, noticing that the system packs an Intel Core i7-4790K "Devil's Canyon" CPU. We hardly need to point out that it is rather intriguing to see AMD use its largest competitor's CPU in its own product, when AMD is a CPU maker itself.

Today an article revisits the process of rendering a frame of the game by reverse-engineering the API calls made to the GPU. All the techniques and algorithms are explained in detail, many of them still used in current video games.
MojoKid writes: AMD announced new Radeon R9 and R7 300 series of graphics cards earlier this week, and while they are interesting, they're not nearly as impressive as AMD's upcoming flagship of AMD GPU, code named Fiji. Fiji will find its way into three products this summer: the Radeon R9 Nano, Radeon R9 Fury, and the range-topping (and water-cooled) Radeon R9 Fury X. Other upcoming variants like, AMD's dual-Fiji board, were teased at E3 but are still under wraps. However, while full reviews are still under embargo, the official specification of the Radeon R9 Fury X have been revealed, along with an array of benchmark scores comparing the GPU to NVIDIA's GeForce GTX 980 Ti. Should the numbers AMD has released jibe with independent testing, the Radeon R9 Fury X looks strong and possibly faster than Nvidia's GeForce GTX 980 Ti.
MojoKid writes: Today AMD announced new graphics solutions ranging from the bottom to the top ($99 on up to $649). First up is the new range of R7 300 Series cards that is aimed squarely at gamers AMD says are typically running at 1080p. For gamers that want a little bit more power, there's the new R9 300 Series (think of them as R9 280s with higher clocks and 8GB of memory). Finally, AMD unveiled its Fiji graphics cards that feature onboard High Bandwidth Memory (HBM), offering 3x the performance-per-watt of GDDR5. Fiji has 1.5x the performance-per-watt of the R9 290X, and was built with a focus on 4K gaming. The chip itself features 4096 stream processors and is comprised of 8.9 billion transistors. It has a graphics core clock of 1050MHz and is rated at 8.6 TFLOPs. AMD says there will also be plenty of overhead for overclocking. Finally, AMD also took the opportunity to showcase its "Project Quantum," which is a small form-factor PC that manages to cram two Fiji GPUs inside. The processor, GPUs, and all other hardware are incorporated into the bottom of the chassis, while the cooling solution is built into the top of the case.
mikejuk writes: Microsoft, after putting a lot of effort into persuading us that Universal Apps are the way of the future, pulls the plug on Skype modern app, to leave just the desktop version. Skype is one of Microsoft's flagship products and it has been available as a desktop Win32 app and as a Modern/Metro/WinRT app for some time. You would think that Skype would support Universal Apps, there are few enough of them — but no. According to the Skype blog: 'Starting on July 7, we're updating PC users of the Windows modern application to the Windows desktop application, and retiring the modern application.' Microsoft is pushing Windows 10 Universal Apps as the development platform for now and the future, but its Skype team have just disagreed big time. If Microsoft can't get behind the plan why should developers? (Also at Windows Central and VentureBeat.)
An anonymous reader writes: Valve's new game engine is looming, and it doesn't just mean changes to the company's most popular games for all players, but also two of the most popular eSports in the world right now, Dota 2 and Counter-Strike: Global Offensive. As a new article points out, Source 2's ability to process more on screen at once, even on feeble laptops with integrated graphics, could have a surprising benefit for top tier play and both games as a spectator sport. After all, if more players all over the developing world can access these games, we could see an uplift in the quality of play at the highest tournament level sometime down the line.
MojoKid writes: A fresh alleged leak of next AMD Fiji graphics info has just hit the web and there's an abundance of supposedly confirmed specifications for what will be AMD's most powerful graphics card to date. Fiji will initially be available in both Pro and XT variants with the Fiji Pro dubbed "Fury" and Fiji XT being dubbed "Fury X." The garden variety Fury touts single-precision floating point (SPFP) performance of 7.2 TFLOPS compared to 5.6 TFLOPS for a bone stock Radeon R9 290X. That's a roughly 29-percent performance improvement. The Fury X with its 4096 stream processors, 64 compute units, and 256 texture mapping units manages to deliver 8.6 TFLOPS, or a 54-percent increase over a Radeon R9 290X. The star of the show, however, will be AMD's High Bandwidth Memory (HBM) interface. Unlike traditional GDDR5 memory, HBM is stacked vertically, decreasing the PCB footprint required. It's also integrated directly into the same package as the GPU/SoC, leading to further efficiencies, reduced latency and a blistering 100GB/sec of bandwidth per stack (4 stacks per card). On average HBM is said to deliver three times the performance-per-watt of GDDR5 memory. With that being said, the specs listed are by no means confirmed by AMD, yet. We shall find out soon enough during AMD's E3 press conference scheduled for June 16.

An anonymous reader writes: Intel has often been portrayed as the golden child within the Linux community and by those desiring a fully-free system without tainting their kernel with binary blobs while wanting a fully-supported open-source driver. The Intel Linux graphics driver over the years hasn't required any firmware blobs for acceleration, compared to AMD's open-source driver having many binary-only microcode files and Nouveau also needing blobs — including firmware files that NVIDIA still hasn't released for their latest GPUs. However, beginning with Intel Skylake and Broxton CPUs, their open-source driver will now too require closed-source firmware. The required "GuC" and "DMC" firmware files are for handling the new hardware's display microcontroller and workload scheduling engine. These firmware files are explicitly closed-source licensed and forbid any reverse-engineering. What choices are left for those wanting a fully-free, de-blobbed system while having a usable desktop?
MojoKid writes: AMD previously only teased bits of detail regarding their forthcoming 6th Generation A-Series APU, code named "Carrizo," as far back as CES 2015 in January and more recently with AMD's HSA (Heterogenous System Architecture) 1.0 spec roll-out in March. However, the company has officially launched the product today and has lifted the veil on all aspects of their new highly integrated notebook APU. Carrizo has been optimized for the 15 Watt TDP envelope that comprises the bulk of the thin and light notebook market currently and it brings a couple of first to integrated notebook chip designs. AMD's Carrizo APU is the first SoC architecture to fully support the HSA 1.0 specification, allowing full memory coherency of a shared memory space for both CPU and GPU up to 32GB. It's also the first integrated chip to include full support in hardware for H.265/HEVC HD video decoding and finally, Carizzo is also the first AMD APU to have a full integrated, in silicon, Southbridge controller block. So, with its CPU, GPU, memory controller, Northbridge, Southbridge, and PCIe 3.0 links, Carrizo is truly a fully integrated System On A Chip. The company is claiming a 39% CPU performance lift (combination clock speed and IPC) and up to a 65% in graphics, versus their previous generation Kaveri APU. AMD notes laptops from major vendors will begin shipping in the next few weeks.
MojoKid writes: The high speed Thunderbolt interface standard, which is used for everything from hyper-fast external storage solutions to external graphics cards, has been slow to take off. You can blame the high-priced Thunderbolt peripherals and the uber-expensive cables (at least when compared to your garden-variety USB cables). For most people, USB 3.0 is "good enough" and making a huge investment into the Thunderbolt ecosystem has been reserved for those in the professional video editing arena. However, Intel is looking to change all of that with Thunderbolt 3. Thunderbolt 3 once again doubles the maximum bandwidth, this time jumping from 20Gbps to a whopping 40Gbps. While that is impressive in its own right, the truly big news is that Thunderbolt 3 is moving away from the Mini DisplayPort connector and is instead adopting the USB-C connector. As a result Thunderbolt will also support USB 3.1 (which is currently spec'd at 10Gbps) and can optionally provide up to 100W of power (in compliance with the USB Power Delivery spec) to charge devices via USB-C (like the recently introduced 12-inch Apple MacBook).
edxwelch writes: Intel has finally released their Broadwell desktop processors. Featuring Iris Pro Graphics 6200, they take the integrated graphics crown from AMD (albeit costing three times as much). However, they are not as fast as current Haswell flagship processors and they will be soon superseded by Skylake, to be released later this year. Tom's Hardware and Anandtech have the first reviews of the Core i7-5775C and i5-5675C.
jones_supa writes: The Linux Mint team has just announced that Cinnamon 2.6 desktop environment is considered stable and ready to download. It is a big update. The load times have been greatly improved and unnecessary calculations in the window management part are dropped, leading to a 40% reduction in the number of CPU wakes per second. Other improvements include a screensaver that does more than just lock the screen, panels that can be removed or added individually, a much better System Settings panel that should make things much clearer, a cool new effect for windows, and a brand new plugin manager for Nemo. Linux Mint users will receive the new Cinnamon as an update by the end of the month.
Deathspawner writes: In advance of the rumored pending launch of AMD's next-generation Radeon graphics cards, NVIDIA has decided to pull no punches and release a seriously tempting GTX 980 Ti at $649. It's tempting both because the extra $150 it costs over the GTX 980 more than makes up for it in performance gained, and despite it coming really close to the performance of TITAN X, it costs $350 less. AMD's job might just have become a bit harder. Vigile adds The GTX 980 Ti has 6GB of memory (versus 12GB for the GTX Titan X) but PC Perspective's review shows no negative side effects of the drop. This implementation of the GM200 GPU uses 2,816 CUDA cores rather than the 3,072 cores of the Titan X, but thanks to higher average Boost clocks, performance between the two cards is identical. And at Hot Hardware, another equally positive, benchmark-laden review.
Billly Gates writes: Ars Technica has the scoop on a new build with less flat icons and a confirmation of a mid July release date. While Microsoft is in a hurry to fix the damage done by the Windows 8 versions of its operating system, the next question is, is ready for prime time? On Neowin there's a list of problems already mentioned by MS and its users with this latest release, including Wi-Fi and sound not working without a reboot, and users complaining about tiles and apps not working in the new start menu.
Earlier this week, NVIDIA officially launched its SHIELD Android TV set-top device, with far more horsepower than something like Roku or Apple TV, but on par with an average game console, and at a more affordable price tag of $199. MojoKid writes: What's interesting, however, is that it's powered by NVIDIA's Tegra X1 SoC which features a Maxwell-derived GPU and eight CPU cores; four ARM A57 cores and four A53s. The A57 cores are 64-bit, out-of-order designs, with multi-issue pipelines, while the A53s are simpler, in-order, highly-efficient designs. Which cores are used will depend on the particular workload being executed at the time. Tegra X1 also packs a 256-core Maxwell-derived GPU with the same programming capabilities and API support as NVIDIA's latest desktop GPUs. In standard Android benchmarks, the SHIELD pretty much slays any current high-end tablet or smartphone processor in graphics, but is about on par with the octal-core Samsung Exynos in terms of standard compute workloads but handily beating and octal-core Qualcomm Snapdragon. What's also interesting about the SHIELD Android TV is that it's not only an Android TV-capable device with movie and music streaming services like Netflix etc., but it also plays any game on Google Play and with serious horsepower behind it. The SHIELD Android TV is also the first device certified for Netflix's Ultra HD 4K streaming service.
MojoKid writes: Dell recently revamped their M3800 model to better entice graphic designers, engineers, and other high-end users who often work in the field, with a true mobile workstation that's both sufficiently equipped to handle professional grade workloads and is thin and light to boot. Dell claims the M3800 is the "world's thinnest and lightest 15-inch mobile workstation" and at 4.15 pounds, it could very well be. In addition, ISV tools certifications matter for workstation types, so the M3800 gets its pixel pushing muscle from an NVIDIA Quadro K1100M GPU with 2GB of GDDR5 memory. Other notable specs include an Intel Core i7-4712HQ quad-core processor, 16GB of DDR3L memory, and a 256GB mSATA SSD. One of the new additions to the M3800 is a Thunderbolt 2 port with transfer speeds of up to 20Gbps that allows for the simultaneous viewing/editing and backing up of raw 4K video. Finally, the M3800 is equipped with a 3840x2160 native resolution IGZO2 display, which equates to a 60 percent increase in pixel density over a current gen MacBook Pro with Retina display. Performance-wise, the M3800 holds up pretty strong with standard productivity workloads, though as you can image it excels more-so in graphics rendering throughput.
An anonymous reader writes: Originally created as a Unreal Engine 4 demo scene to push the limits of VR-capable graphics on the Oculus Rift 'Crescent Bay' prototype VR headset, Showdown is now running flawlessly at 60 FPS on Morpheus, Sony's PS4 VR headset. The demo was previously only able to run at Oculus' 90 FPS target VR framerate on the Nvidia GTX 980, a GPU which costs nearly $200 more than the PS4 itself. To the delight of UE4 developers, the performance improvement comes from general optimizations to UE4 on PS4, rather than specific optimizations to Showdown.
