As a linux-only user (and gamer), nvidia is a plain no-go for me so i just hope that rdna2 is not entirely disappointing like RDNA1 was. For us Linux gamers a working VFIO on a consumer card would be a dream of course since nvidia is locking that to their workstations cards, maybe AMD just throws it in as a goody. Zen3 is propably gonna kick-butt, especially in any non-gaming task perhaps AMD will inch closer to Inte…

I have had perfect working VFIO setups with both the 1070 and 1080ti from nVidia, there are many comprehensive guides and working around the driver error code 43 is quite trivial.

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.

What about the Mac side of things ? Mac's are still pretty big in audio production, but they don't support CUDA (and don't come with Nvidia GPUs any more anyway). How does Metal Compute stack up ?

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-...

Some of the leaked benchmarks for the 3080 put it more in the range of 30-50% better than the 2080 series:

"30% Faster Than The RTX 2080 Ti & 50% Faster Than the RTX 2080 SUPER on Average"

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?

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

I'm not sure what part of 'the industry' you're referring to, but last time I looked (which was admittedly more than a year ago), there is only one serious SYCL implementation, it's proprietary and the only people pushing SYCL are... drum roll... the people selling that implementation. That's not even considering that OpenCL is in most cases (way) behind CUDA in performance, not to mention that the tooling for OpenCL is outright primitive. And all of that is not even mentioning that nvidia drags their feet massively in supporting newer OpenCL version on their GPU's.

Maybe things have changed massively very recently, but I came back from iwocl (the OpenCL and SYCL conference) two years ago massively disappointed. And I still don't see anyone in the slice of the HPC space I'm familiar with (environmental & GIS-related modeling) using it, for a reason I presume.

unless you have navi, in which case rocm is not supported and doesn't work and I guess AMD expects you to use opencl.

Navi just began to compile a week or two ago. Still 'unsupported', but its slowly gaining features. ROCm is a bit uneven with what cards it supports. Ex: Rx 550 never was supported (even though Polaris, the rest of the 5xx series worked). It seems like the only cards ROCm works for are the ones that share a chip and/or driver with AMD's "Machine Intelligence" line of cards. (MI50, MI60, etc. etc.). Which are Fiji (Rx…

Last time I tried, PCIe 3.0 was also a requirement, although that wasn't much of an issue unless it was some nonstandard configuration like an RX 580 in a junkyard find A4 APU machine.

Wouldn't SR-IOV support (which is rumored in nvidia's chips) make vfio on this kind of setup possible?

VFIO doesn't work with Nvidia devices because of a design decision by Nvidia. Their drivers refuse to load in a virtualized setting unless you buy their enterprise GPUs. You can patch out a few checks and everything works again. Another option is to reload the GPU firmware before the virtualization host boots so the GPU doesn't know it's the second time it boots.

Even if it's possible to implement proper VFIO for Nvidia GPUs, I expect them to fight such an implementation with tooth and nail in their drivers. This is the same company that artificially limits the amount of transcoding streams in their drivers, mind.

Apple Silicon will contain an Apple-designed GPU, so it might soon be irrelevant for Mac users what AMD has to offer.

I highly suspect Apple will still ship (and support) AMD GPUs - maybe for the iMac Pro and Mac Pro. I doubt that Apple Silicon GPUs will be close to the performance to AMD/NVidias flagships. And I assume the market share for iMac/Mac Pro is just not that big for Apple to invest in competing with AMD/Nvidia on the Highend Segment.

OTOH Apple also needs dedicated GPUs for some of their MBPs and the bigger iMacs.

I think they will end up ditching AMD to have 100% E2E control on all their products.

Depends on price. Nvidia might have owned the tippity top with their 20xx series but the 5700xt was a very strong card for medium priced builds and as a pc building enthusiast would’ve been the card for my next build alongside an amdR5 3600 cpu. At launch it had driver issues but they were cleaned up and at $350 it was a total steal compared to a 2070 at $650 for similar performance.

AND those early benchmarks were from Nvidia on very specific DLSS and RTX workloads that may not have been representative to many games people play.

Very excited about this. I wasn't really a fan of AMD, but I built a machine with a Ryzen 3700X last year and I've been super impressed.

Personally I don't really care if RDNA2 is not as powerful as the Ampere GPUs as long as the price is competitive. I want to update my 1070 just for playing Cyberpunk 2077 when it comes out, but since I don't play that much anymore it doesn't make sense to go all-in on the GPU.
