People buy Nvidia no matter what. Even when they aren't the best choice. Then those same people complain about Nvidia doing the anticompetitive things they do.
The best is when people cheer for AMD making something great, only so they can buy an Nvidia card cheaper, as if the only reason AMD exists is to subsidise their Nvidia purchase!
Nvidia's greatest asset is the mindshare they have.
Well that and CUDA still means a load of professionals in various fields are stuck using Nvidia whether they like it or not. This means data centers are incentivised to go with Nvidia if they want those customers, which ultimately means if someone gonna work on code/tools that run in those data centers, you want the same architecture on your local machine for development and testing.
It's getting better, but the gap is still real. Hopefully the guys that are working on SCALE can actually get it working on the CDNA GPUs one day, since data centers are where a lot of the CUDA is running or perhaps the UDNA stuff AMD just announced will enable this.
The fact this is all hinging on the third party that develops SCALE, should highlight that AMD still doesn't seem to be playing the same game as Nvidia, which is why we're still in this position.
Definitely. CUDA has had a long headstart, and Nvidia were very clever in getting it entrenched early on, particularly in universities and such. It's also just... generally does the job.
I would have much preferred giving AMD money instead, but at their best the lack of DLSS performance was meaningful when everyone thought Cyberpunk was the new standard of graphical fidelity with the 6000/3000 series.
The linear algebraic computations performed on their GPU's tensor cores (since the Turing era) combined with their CUDA and cuDNN software stack have the fastest performance in training deep neural network algorithms.
That may not last forever, but it's the best in terms of dollars per TOPS an average DNN developer like myself has access to currently.
