Earlier quoted context omitted.

The people that use CUDA don't care about the underlying architecture, they need results. Which ever manufacturer will deliver those results will get the $. Raytracing is not an ideal match workload wise for a GPU, too much divergence, but there are plenty of workloads where GPUs will have an edge for along time to come.

It's more than that - NVIDIA invested massively in their software ecosystem and mindshare (e.g. by a huge sponsoring program that saw universities flooded with their hardware). AMD cards offer comparable compute performance and are sometimes even better. What AMD lacks, though, are ready-to-use software packages like CUDA, cuDNN, cuBLAS, and the like. NVIDIA basically bought their way into the research community and…

I assure you, the affected scientists who have to fight tooth and nail for funding are less than impressed that they are dependent on the mercy of a single vendor.

Does that mean more than 256GB of RAM without having to go for an EPYC?

I feel like 64 cores is getting rather close to a tipping point: What workloads are so massively parallel that they can use 64 cores of x86 but can’t use the thousands of CUDA cores on a Quadro card? I’m sure right now there are workloads that just need particular x86 instructions, but that feels like a temporary problem. Am I wrong about that being a temporary problem (that would feel frustrating)? Are these cores j…

The impending doom that is WASM will mean that 'dynamic' and 'interactive' adverts will use all these cores.

The article mentions support for up to 2 TB of RAM.

CPUs are much more general! Unscientifically, on my 2950X/1070Ti workstation, Cycles takes approximately the same amount of time to raytrace a scene on the CPU vs the GPU. I think this is a great example of a highly parallel workload that is challenging for GPUs due to lack of coherence - extreme props to the Cycles team for making it work on GPU at all. Also, year-on-year performance increases for nVidia GPUs are re…

Not only that but there are features in Blender that cannot be rendered using Cycle GPU mode but work fine using Cycles CPU mode.

On the other hand, wasn't GPU mode added much later than CPU mode? Maybe there has been less development time put into it.

Any compiler that can properly use multiple cores could potentially benefit. Rust (and Haskell's GHC) uses all 8 cores I have during a sub-period of recompilation, so I'd guess it could as well use more.

I know GHC can become slower with more cores so be carefull.

64 cores? how much would that cost? around $1k or more? is this for the consumer line or server line of products?

The 64-core 3990x is MSRP $4000. I’d expect this new fangled 3995WX to be that much or more.

And as comparison, the 12-core is $500 and the 16-core is $750, both currently available for 10-15% off.

What a miserable hopeless post - "they're going to fuck us and what can we do????".

Answer: quite a lot, if you have even minimal technical understanding (like, enough to use a blocklist or an ad blocker). Are you incapable even of that?
