The information available around Big Navi (The GPUs expected to launch next month) put them at a +50% performance jump from the last generation and likely able to compete with the Nvidia flagship 3080: https://www.tomshardware.com/news/amd-big_navi-rdna2-all-we-...

It is important to note that it is 50% performance improvement per watt, not absolute performance.

In at least datacenter settings, performance-per-watt is just as important as performance-per-dollar, since watts are continuous OpEx.

The industry at large is moving to SYCL, which can be implemented on top of OpenCL / CPUs / FPGAs.

Oh, the third option, with absolutely no library support. Or, looking at Khronos's page, even device support. At least OpenCL has the benefit of wide compatibility, even if its performance meant it was unsuitable. Nvidia has settled on CUDA, and has maintained 13 years of compatibility. If SYCL is going to ever compete with CUDA, it's going to need to stick around long enough for people to build on it.

My firm does GPGPU programming for audio processing. Nobody in this area even thinks of using anything other than CUDA. It has far more support, tools, compilers, etc.

Chips are in the pipeline for many years, so products being released today are probably on the tail end of being impacted by AMD cutting GPU budgets to the bone to focus on Zen. I wouldn't expect miracles. Given AMD's market cap and financial success, I bet they're working on competitive designs now. There's no money in being an also ran in the space.

But nVidia was substantially ahead the last generation and are promising a greater performance delta than that.

AMD often has very high FLOPS but fails to translate that in to FPS in games, due to architecture inefficiency, drivers, or developers simply optimizing primarily for GeForce.

I would in turn urge you to take all of these figures with a large grain of salt until the third party benchmarks hit.

Rumor has it AMD has a competitive GPU but will not pursue the high-end market mostly because of their limited TSMC slots, they can make much more money from a CPU wafer than a GPU one ( due to area size and yield ) But I really hope I'm wrong and they kick Nvidia ass since they become such intolerable arrogant anti-competitive pricks in the last +10 years.

The last time I owned an AMD video card was more than a decade ago. At the time their video card drivers needed work and could blue screen your box. There was a lot of back and forth on the internet about which driver version to load to get the most stable experience. Fast forward to 2020 and the perception about AMD's video driver quality seems to be in a similar place: https://www.pcgamesn.com/amd/radeon-big-navi-d…

Maybe for Windows, but the same cannot be said of Linux or macOS, where AMD's choice to open-source their drivers has led to these OSes having great support; while Nvidia, having to support their own closed-source drivers, seemingly hasn't had the bandwidth to get their drivers for these OSes up to par.

With Intel stuck in process hell for a while longer, I primarily hope AMD can gain ground on Nvidia. They are pushing a lot of innovation and gaining market dominance, both in the ML/GPGPU space and gaming (with ray tracing, upscaling, etc). We need some competition to keep prices low and innovation high medium to long term.

What's their CUDA competitor this year? Are they pushing out client libs for Vulkan or are we sticking with trying to make ROCm work?

ROCm and HIP - https://github.com/ROCm-Developer-Tools/HIP, as it has been for the last 3-4 years

Besides processors, AMD knows how to design a good hype train.

The major difference is that they have a product to back it up. Also, a large part of the hype comes from the "market" and you can blame Intel and Nvidia for that, since they have been screwing and exploiting said "market" for more than a decade now.

It was already a dire situation running a Mac with eGPU or a Hackintosh even before the RTX 30-series announcement, and much more dire after that. The likeliness of Apple allowing NVIDIA to produce Mac drivers again is close to zero. It’d be nice for AMD to be able to compete with GPUs again.

What do you even do with a GPU on a Mac these days? I guess there are a decent amount of games now, but it seems like it'd be mostly limited to "creative" stuff since CUDA is out of the question. Imagine how much more dire it's going to get once Apple has ditched Intel. Are they going to continue using third-party, discrete GPUs? You definitely won't be able to use one off the shelf (at least without flashing the car…

They would have been putting tons of development money into the graphics for the PS5 and the XBOX, and I think a lot of what went in to that is going to show up in their new GPUS. The timing of this stuff coming out right alongside the next generation consoles is confirmation of that, I think.

TSMC slots are transferrable/sellable... The fact Nvidia hasn't sold their slots to AMD for CPU production, yet AMD's GPU team has given up slots to their CPU team, tells you Nvidias GPU range is more profitable than AMD's one in this high-end market.

For this generation, NV only makes the flagship datacenter/professional GPUs/A100 on TSMC, smaller GPUs are made on Samsung's 8nm process.
