AMD Launches New GPU And EPYC CPU Right Across NVIDIA’s Bow – Forbes

Published

on

One year ago I complained that the newly announced AMD MI100 GPU was great for HPC, but inadequate for most AI workloads. Now AMD has announced the upgraded Instinct MI200, designed in large part to fulfill the needs of the US DOE Exascale program. The chip has astonishingly fast HPC performance, and decent theoretical AI performance. AMD also teased an upgrade to the EPYC CPU, with a massive 3D stacked memory V-cache for faster HPC performance, with a cache coherent fabric that can connect four MI200’s to the EPYC CPU. Let’s take a look.
Well, technically the company did not announce these new platforms; they previewed them to get the limelight before SuperComputing ‘21 to be held in St. Louis on November 14-19. And since Oak Ridge National Labs is already installing these chips in the HPE Cray Frontier Exascale system, well, they had to say something. But while some details and pricing are not yet available, there is still plenty of news to excite the HPC and AI community
Let’s start with the updated EPYC Milan CPU. Many HPC and AI apps are memory bandwidth constrained. By tripling the CPU’s cache with 3D stacked memory to 804MB per socket, AMD is seeing a 50% average improvement in “targeted” HPC applications such as EDA, Mechanical engineering, and computational fluid dynamics. In fact, the company demonstrated greater than 60% better performance for the Synopsys verification application. Since many (most) HPC applications are priced by the number of cores in a server, increasing performance per core dramatically lowers the total cost of ownership for engineering systems. However AMD pricing was not disclosed. The new “MilanX” will be launched in Q1 2022.
MilanX has three times the cache of the original 64-core x86 CPU.
The new MilanX demonstrates significant performance improvements over the already-leading Milan CPU.
Then check out this new two-die GPU, the Instinct MI200. The design team knew who their first customers would be, as the Frontier and El Capitan Exascale systems for the US DOE had already been awarded to HPE and AMD when the chip was still on the drawing board. While AMD let it slip that the chip would burn some 550 watts (!), it will deliver nearly five times the 64-bit floating point performance for HPC workloads, compared to the NVIDIA A100, so performance per watt will still be astounding.
The MI200 has 2 CDNA GPU’s on the package, and eight stacks of HBM2E fast (and expensive) memory.
As for AI performance, AMD has closed the considerable gap with NVIDIA, at least in terms of theoretical performance, based on 16-but floating point FLOPS that is 20% higher than the NVIDIA A100. We say “theoretical” because AMD is not yet ready to disclose AI benchmark results such as the MLPerf suite. And we suspect it will take some time for the Instinct software team to optimize AI models, kernels, and the ROCm development stack, so don’t hold your breath. But we do believe that the performance will attract developers to begin the journey to create an AI ecosystem around AMD.
Two other features bear noting. One is the performance and memory coherency of the new Infinity fabric that interconnects the GPUs to MilanX, and presumably Milan. Cache coherency greatly simplifies memory management for software developers, improves application performance and enables multi-billion or trillion-parameter AI models. And of course the performance of these direct links will blow away PCIe-based GPU architectures.
The other new technology is called the Elevated Fan-out Bridge (EFB), that replaces the traditional silicon transposer. EFB promises higher scalability and lower costs, leveraging standard “flip chip” processes to simplify assembly.
AMD has developed a new packaging approach to improve performance and cost of multi-chiplet … [+] platforms.
AMD disclosed on the analyst conference call that they have not submitted any benchmarks to MLCommons. We hope they do in the next round of benchmarks, but would not be surprise if the company choses not to. Closing the gap with NVIDIA for AI is as much of a software challenge as a silicon one, and that will take time. However, AMD did share raw Flop performance numbers to substantiate their marketing claims that the new platform is potentially nearly 5-times fast than NVIDIA. Potentially.
AMD disclosed impressive performance data, claiming up to 4.9X the performance of the NVIDIA A100.
Looking beyond raw FLOPS for some real performance comparisons, the MI200 looks to be roughly 1.5 to 3 times NVIDIA GPU performance for HPC. Unfortunately, no AI application performance data were disclosed.
AMD Shared real application performance data for HPC that demonstrated significant advantages over … [+] NVIDIA.

Clearly AMD is fulfilling CEO Lisa Su’s promise to build its data center business from HPC on down. MilanX and MI200 combine to deliver excellent HPC performance and scalability which will be substantiated in the Exascale systems being built and planned.
On the other hand, AI seems to have been relegated to a lower priority once again, both on the EPYC CPU when compared to Intel Sapphire Rapids and the GPU when compared to NVIDIA. While 20% better 16-bit floating point is nice to see, FLOPS is a poor performance predictor in the software-driven world of optimized AI acceleration.
All said, however, I cannot argue with AMD’s prioritization: as NVIDIA focuses more on AI, it has created vulnerability in HPC which AMD intends to exploit.

Sony's wild new PS5 controller concept could be a game-changer – Creative Bloq

(Quite literally.)
It’s fair to say we weren’t enamoured with the design of Sony’s DualSense controller when it was revealed last year. Like the PS5 itself, the controller is somewhat, er, chonky – but it seems Sony is already working on slimmer design concepts.
A new patent filing reveals the company is working on a new controller design featuring a collapsible control stick. This means the joystick could retract into the body of the controller itself, allowing for a more svelte (and potentially more comfortable) design. And while it might just be a patent, at this rate it might well arrive before the next PS5 restock
PS5 patent
The patent filing itself offers little in the way of information about how the controller will work, simply describing: “A controller, thumbstick, or system comprising a thumbstick body, a thumbstick shaft coupled to the thumbstick body wherein the thumbstick shaft is configured to retract into the thumbstick body and wherein the thumbstick body and the thumbstick shaft is freely rotatable together around a pivot centre within the controller body.” (You know when you read a word so many times that it loses all meaning? Yeah, thumbstick.)
But it seems the concept is all about comfort. “Analog nubs are portable but also very uncomfortable for the user,” Sony says in the filing. “The user moves the flat surface or rough area with pressure from their thumb. This can become quite uncomfortable after a while because the required friction between the user’s thumb and the surface.” 
As with all patents, whether this design will ever see the light of day remains to be seen, but it’s certainly intriguing – and we can’t help but wonder if it’s offering us a glimpse of the next generation of DualSense. If a PS5 ‘Slim’ ever makes it to market (hey, every PlayStation generation has had one), perhaps it’ll arrive complete with a redesigned controller?

Indeed, a collapsible thumbstick could potentially transform the feel of the controller for gamers, offering a much more personalised and therefore comfortable experience. And it could do wonders for storage too – perhaps we’ll even end up with some kind of ‘DualSense Slim’ charging case. And we’re sure it could look pretty cool – better than that horrendous McDonald’s DualSense concept anyway. 
It seems Sony is finally ready to give gamers more options when it comes to the look of the PS5. From those new coloured faceplates to rumours of a console redesign, the days of being restricted to Sony’s reverse-oreo (sorry, white-on-black) design are coming to an end. And perhaps in the near future, we’ll have a brand new controller to enjoy too. Want to start gaming right now? Check out today’s best games console deals below.

Home » Guides » Rainbow Six Extraction: Is It PS5 & Xbox Series X Enhanced? Answered
In Ubisoft‘s latest tactical first-person shooter, Rainbow Six Extraction, you’ll be spending a lot of your time gunning down waves of parasitic alien critters known as the Archaeans. On the whole, all the moment-to-moment action is pretty damn slick visually, but what if you’re playing on next-gen consoles? In this guide, we’ll answer the all-important question: Is Rainbow Six Extraction enhanced on PS5 and Xbox Series X consoles? Without further ado, let’s get into it.
Thankfully, the short answer is: Yes, Rainbow Six Extraction is indeed enhanced on PS5 and Xbox Series X. Those playing on next-gen consoles can look forward to a 4K resolution boost and 60 frames-per-second gameplay.
For comparison’s sake, those playing on PS4 and Xbox One, you’ll be limited to just a 1080p resolution and 30 frames-per-second, which is understandable.
Unfortunately, for those wondering if Rainbow Six Extraction will support 120 frames-per-second on high-refresh-rate TVs, we’ve got some bad news for you. At the time of writing, there’s currently no support for 120fps for Rainbow Six Extraction on consoles.
It could be possible that Ubisoft deploys a patch allowing high-refresh-rate support for Rainbow Six Extraction in the future. However, there’s no official word on it just yet. That said, we’ll make sure to update this post if we hear anything more concrete.
But that’s about everything you need to know about whether Rainbow Six Extraction is enhanced for PS5 or Xbox Series X. For more tips, tricks, and guides, search for Twinfinite, or head on over to our dedicated wiki for the game. And for any questions you have that aren’t answered on the site, do feel free to reach out in the comment section below and we’ll do our best to lend a hand.
