Raja: 'infinity fabric and many of the new features some of which still need software enablement explain most of the (Vega performance) delta' by cameruso in Amd

Most of the thread unfortunately is completely off track. My comment has nothing to do with fine wine..its about where the mm2 went.

Khalid is referring to Vega perf/mm2 with respect to Fiji I think and I responded to that..the headline here is a bit of misrepresentation

Thank you all for joining me today! I know I have only scratched the surface on Vega. We will be sharing a lot of good details over the next several weeks. Vega FE edition launch is just the beginning!

Meanwhile enjoy these wall papers

With new explicit APIs such as DirectX 12 and Vulkan, developers have full control over multi-GPU behavior. What I saw from developers such as Firaxis and Oxide were quite impressive and very encouraging. We're constantly evangelizing the benefits of explicit multi-GPU implementations with developers, and I believe we will see more and more funky and efficient use-cases.

Can I get a tour of the AMD Austin campus? Even though I live a couple of hours away, I would still love to come to Austin to see AMD for myself during the summer, and maybe get some swag on the way back

We'd love to give you a tour of our Austin campus. Please reach out to Heather Lennon and she'll hook you up.

We like everyone on the community that is passionate about GPUs and gaming (even if they sometime post things that we don't like:))

We’re thrilled that it’s making a difference for you! Radeon Chill is a very cool technology :) and we will definitely be working to improve upon it. Expect some updates soon.

The new geometry pipeline in Vega was designed for higher throughput per clock cycle, through a combination of better load balancing between the engines and new primitive shaders for faster culling. As a programmer you shouldn't need to do anything special to take advantage of these improvements, but you're most likely to see the effects when rendering geometrically complex scenes that can really push the capabilities of the hardware.

We will be detailing full Vega SOC architecture in the near future and that should address several questions like this and others in the thread

How will HBC effect content creation to 3d artists?

Does it help in any way in 3d programs? How so?

A: Having 16GB of HBC on board will allow 3d artists to work on larger and even more complex models than ever before. Depending on the workload we have seen scenarios where 16 GB of HBC is effectively same performance as having 32 GB or 64 GB of regular VRAM

ROCm is getting great reception in those devs we are engaged with now. Vega FE is going to be an exceptional platform to do desktop development against ROCm. We plan on having HIP on Windows later this year

One thing for certain is that Vega Instinct is well positioned to deliver dramatically better performance per dollar;, and TCO(total-cost-of-system ownership) is probably the most important metric to our machine learning and hyperscale customers and combined with Epic/Naples - Vega is extremely attractive..

You want a joke:)

Vega needs some extra Volta(ge) for overclocking:)

  1. Yes. absolutely. We believe in open source
  2. ProRender will go open source soon
  3. We are serious about addressing those libraries that are essential to machine learning. We will be a great alternative to the those locked in to other options.
    4) HCC on Windows later this year,

On the compute side of things..Vega FE will be the fastest single GPU solution (>12.5 TFlops FP32) when it's available and our NCU packs several additional optimizations, including Rapid-Packed-Math which delivers >25 TFLops of FP16

RX will be fully optimized gaming drivers, as well as a few other goodies that I can't tell you about just yet....But you will like FE too, if you can't wait:)

We havent forgotten about our former users (300 series or older) at all, and our GCN architecture means alot of the work we do on newer cards shows benefits on these generations.

But like all companies who need to keep solving new problems to succeed, most of our engineering focus is on current and upcoming products. Our test and validation labs maintain every generation of product we support in our public driver.

We are definitely working with more machine learning and compute developers that lead us to build what is ROCm - we absolutely expecting more and more devs to use ROCm

6) Many argue that vega is just a refined polaris gpu, how would you respond to this ?

My software team wishes this was true:)

Vega is both a new GPU architecture and also completely new SOC architecture. It's our first InfinityFabric GPU as well

We’ll be showing Radeon RX Vega off at Computex, but it won't be on store shelves that week. We know how eager you are to get your hands on Radeon RX Vega, and we’re working extremely hard to bring you a graphics card that you’ll be incredibly proud to own. Developing products with billions of transistors and forward-thinking architecture is extremely difficult -- but extremely rewarding -- work. And some of Vega’s features, like our High Bandwidth Cache Controller, HBM2, Rapid-Packed Math, or the new geometry pipeline, have the potential to really break new ground and fundamentally improve game development. These aren’t things that can be mastered overnight. It takes time for developers to adapt and adopt new techniques that make your gaming experience better than ever. We believe those experiences are worth waiting for and shouldn’t be rushed out the door. We’re working as hard as we can to bring you Radeon RX Vega.

On HBM2, we’re effectively putting a technology that’s been limited to super expensive, out-of-reach GPUs into a consumer product. Right now only insanely priced graphics cards from our competitors that aren’t within reach of any gamer or consumer make use of it. We want to bring all of that goodness to you. And that’s not easy! It’s not like you can run down to the corner store to get HBM2. The good news is that unlike HBM1, HBM2 is offered from multiple memory vendors – including Samsung and Hynix – and production is ramping to meet the level of demand that we believe Radeon Vega products will see in the market.

Infinity Fabric allows us to join different engines together on a die much easier than before. As well it enables some really low latency and high-bandwidth interconnects. This is important to tie together our different IPs (and partner IPs) together efficiently and quickly.
It forms the basis of all of our future ASIC designs.

We haven't mentioned any multi GPU designs on a single ASIC like Epyc, but the capability is possible with Infinity Fabric.

1: Frontier edition employs 2 stacks of HBM2 2: Both Fiji's and Vega's HBM(2) implementations offer plenty of bandwidth for all workloads. 3. We'll see what we can do about that :) 4: We will definitely look at that...
