Apple Preps Next Mac Chips With Aim To Outclass Top-End PCs (bloomberg.com) 207

Posted by msmash from the shape-of-things-to-come dept.
Apple is planning a series of new Mac processors for introduction as early as 2021 that are aimed at outperforming Intel's fastest. From a report: Chip engineers at the Cupertino, California-based technology giant are working on several successors to the M1 custom chip, Apple's first Mac main processor that debuted in November. If they live up to expectations, they will significantly outpace the performance of the latest machines running Intel chips, according to people familiar with the matter who asked not to be named because the plans aren't yet public. Apple's M1 chip was unveiled in a new entry-level MacBook Pro laptop, a refreshed Mac mini desktop and across the MacBook Air range. The company's next series of chips, planned for release as early as the spring and later in the fall, are destined to be placed across upgraded versions of the MacBook Pro, both entry-level and high-end iMac desktops, and later a new Mac Pro workstation, the people said.

[...] The current M1 chip inherits a mobile-centric design built around four high-performance processing cores to accelerate tasks like video editing and four power-saving cores that can handle less intensive jobs like web browsing. For its next generation chip targeting MacBook Pro and iMac models, Apple is working on designs with as many as 16 power cores and four efficiency cores, the people said. While that component is in development, Apple could choose to first release variations with only eight or 12 of the high-performance cores enabled depending on production, they said. Chipmakers are often forced to offer some models with lower specifications than they originally intended because of problems that emerge during fabrication. For higher-end desktop computers, planned for later in 2021 and a new half-sized Mac Pro planned to launch by 2022, Apple is testing a chip design with as many as 32 high-performance cores.

      • The web isn't snappy for several reasons, but from a hardware perspective, the page can only use one core. In this case, Apple has a good chance of lapping intel in the performance of CPUs because the power profile of the M1 is so low compared to its performance. The limiting factor in the CPU package is almost always the heat dissipation limits, which is why it is rare to see a chip beyond 150 or so watts without complex and expensive cooling solutions. Apple's M1 chip in the Mac Mini was measured at a 24w

      Are you joking? JavaScript development is in a pitiful state. We need 4000 frameworks now for reasons I don't understand, but I am told by those more senior than me are best practices. Even pitiful pages spike my CPU constantly on a top of the line macbook pro. I can run intensive data transformation jobs in Java over 30 GB of data more easily than loading HomeDepot.com. It spikes my CPUs more than most 3D shooters. Open up a modern page in the debugger...it's making a shit-ton of pointless calls, some for security and bot management, and most for marketing.

      As it is, if I walk over to my company's UI team and tell them I want to write a modern UI, they spout off a dozen "NEEDED" frameworks, many of which they can't clearly explain to me why they're needed. I don't want to sound like a luddite, so I eventually give up.

      In contrast, my company has a legacy UI, written back in 2005 on Ruby on Rails, the old-style of development where the server rendered everything...it's FUCKING FAST....1000s of rows loading with no latency and such a joy to use (not because of Ruby, but because it's 2005 server-side templating paradigms). I can scroll without my CPU locking up. The layout is a bunch of table tags. It's got CSS and styling and stuff, but it's just so amazing how fast it is. I'm so glad it hasn't landed on the radar of the UI folks.

      On the other hand, homedepot.com, walmart.com, bestbuy.com, starbucks.com...erroneous, slow, spikes CPU, things don't render in time, like where you see the full listing before the price renders on home depot...all this post-web-2.0 crap...where everything has to be done by the client in JavaScript...because apparently server-side rendering is bad now.

      Having done a lot of server-side rendering, I can tell you that it's, by far, the FASTEST part of the equation. The slowest is the DB lookup and queries, which you have whether you're sending the data pre-rendered in HTML or via JSON in a REST call. So only the biggest sites, the gmails and amazons.com of the world, really tangibly save by offloading rendering. For everyone else, it's just an exercise of completely rewriting your UI to make it a LOT less reliable, a lot more painful to use, and a lot more complex.

      It's a big jobs program for people who like to write JavaScript more than making their customers happy. ...or a way for UI/UX developers to passively aggressively spite their users, I'm not sure which.

      All I know is that chrome/Firefox are the biggest CPU piggies on my machine....not eclipse, Oracle SQL Developer, IntelliJ, Visual Studio Code, the Java compiler, even Adobe Lightroom on my personal machine., The local postgres DB I am running, the 3 application servers I have running in the background....nope, when I want to speed up my machine, I close tabs because that speeds it up faster.

      If you told me 15 years ago how much faster CPUs would be, I'd be shocked to learn that browsing the web got SLOWER and more tedious. I figured it would be a utopia having so many cores available and at such a high clockrate and more RAM than I ever needed, but it seems like we've regressed just slightly.

        The issue is with server side templating is/was the network speed to the client. Client side rendering allowed sending 2kb JSON blob rather than 10kb of text and markup again, and it also means the client maybe does not have to do all that object creation to rebuild the DOM for a given frame/window from scratch.

        When SST was mixed judiciously with JavaScript and AJAX requests to update/mutate the local state it was huge win. For certain data intensive applications that are mostly used on the Internet / Slower higher latency links the current SPA paradigm can be a win; less so for internal apps where users are local networks or well connected VPN endpoints.

        However like anything in IT Web/2.0 development came to be dominated by a mixture of cargo-cultists and people who "learned one tool or idea and just want to apply everywhere" and the result of course is some design techniques that can be enormously beneficial get forced into situations where they are sub-optimal at best and often quite harmful because "this is the way"

    • Is there any reason you suspect that Apple won't support 64GB? The current 16MB limitation is a design decision that presumably reduces costs (putting everything on one chip is going to cost less). An Apple Silicon Mac Pro is less cost-constrained and likely will support just as much as the current Mac Pro (I think it is 1.5TB or something like that). Apple is pretty free to change the design of their chip to suit the use-case.

      • You can put 64 GB on a much bigger SOC, still no problem. Above that it gets tricky. Yes, 128 GB will require external RAM, just what we have today. I suppose the 64 GB will be like a massive, massive L4 cache :-)

      Of course they're not going to be able to cram 64G of RAM or more into an SoC, so they'll need a memory controller capable of driving off-board chips. And presumably more PCIe lanes. All of which will eat into the power budget. So I doubt it will be up to the hype, but it's still good.

      1. Is the product suppose to be mobile? Your Phone and Laptop. is expected to be used on the go, with a degree of shocks, and drops. So Soldering makes sense as the components are much more tightly placed.

      2. Do customers want a particular form factor? A socket doubles its width, so more removable parts the bulkier and heaver the product.

      3. Are they competing with price. You see Item A and Item B The specs are the same except for the fact that one costs more.

  • I think that they have a good base to build on going foreward. But for desktop boards they need to be focused more on expandability. They definitely need to support more than 16GB of RAM and probably at least as much as 64 GB for a lot of people. They means they are going to need slotted memory. They are also going to have to support standard off the shelf GPUs from the likes of AMD and NVidia.

      Why? They never have up to now.

      Apple hasn't support NVidia in years and I don't expect that to change anytime soon. They may work with AMD for GPUs, but with the direction Apple is going I imagine they've already started working on their own high-end GPUs and the AMD support would just be a stop-gap measure until Apple Silicon GPUs are ready for release.

      Same goes for things like more USB/Thunderbolt ports and well as display outputs.

    But...

    I'm not going to buy one as long as Apple continues to solder memory to the board and prevent you from upgrading the machine in any meaningful way. That's just a non starter for me. What is far more interesting is the prospect of running Linux on an M1 chipset.

    I suspect that one of the reasons why new x64 chip designs are not faster than they are is due to the desire to use hyperthreading, which complicates the designs. Yes, it may allow you to leverage more of the circuits more of the time on a given core, but at the sacrifice that the fastest single thread performance is impacted. Might it be time to remove hyperthreading from cores, or possibly, craft a chiplet design with four cores without and four cores with. High priority threads get put on the dedicated cores, and lower can run on the shared cores. Win Win

    • The main impact of hyperthreading is one extra bit to compare when resolving dependencies in the re-order buffer. In some other parts of the out-ot-order engine you divide an array in half for each thread; in others you store the thread id and carry it around. The exec stack and the physical register file don't actually know which thread an operation or destination are associated with.

    Now that lithography stuff is advancing more slowly and the end of even EUV is in sight, the war of architectures can resume in earnest. It looks like it will not be about how fat the instruction set is anymore but about sheer power efficiency. Good for Apple to get into this game early enough to potentially take a sizeable chunk of the market.

  • No one seems to mention Apple silicon's potential impact on the server market. They could start with internal consumption. Right now they are selling binned M1 chips with one non-functioning GPU core on their low end Macs. Given the way yields work, they must have many more reject M1s with, say two bad GPU cores, or some bad neural engines, etc. They could slap these essentially-free, low-power processors on simple circuit boards and stuff large numbers into open-server racks to satisfy the growing cloud co

    • There is no point in using a M1 in a server room. The core appears to be great but it obviously designed for the computers it is now being installed into - that is laptops.

      If Apple wants a server room chip they will take several M1 cores and pair them with cache, a wide memory controller supporting ECC memory, PCIe ver 5, and probably a couple 10Gig ethernet ports. Removed would be thunderbolt, the GPU, and the AI optimized core. Now you could have a 64 core powerhouse that would be twice the speed as

      • How many loads in Apple's service portfolio need ECC? Serving music, videos, exercise apps, Siri? GPUs and AI acceleration could be relevant to what they do. And any supporting software development is orthogonal to their core products, so it is easy to do in other countries. Remember, we are talking about essentially free processing silicon, graded out from their Mac production. Of course the higher end silicon the parent article refers to would be even more suitable for servers.
    • What OS would these Apple Silicon servers run? I guess they could run macOS, but that is tuned for desktop tasks instead of server tasks. I also believe that it doesn't support Docker, so there goes a ton of use cases right there.

      ARM is already making huge headway in the server market and there are already companies producing ARM chips with full support for Linux. Apple is far more focused on the consumer market, so I don't expect them to start focusing on servers and enterprise, especially given that

    And I say that as somebody, with iUsees in the family, who would love to up their low ego with iShinies, but can't, because Apple simply removed the functionality required for professional work. E.g. in Final Cut Pro. Which has become a consumer toy. And the whole OS moving towards becoming desktop iOS.
