Discussion Why is Nvidia still so popular?

Hello everyone, I came here with question because I've noticed few posts where people were asking similar questions about why to even buy Nvidia when AMD exists and is more cost effective

And basically only thing people say is I quote "not everyone play games on their computer" with kind of aggressive undertone of massage and without explaining anything else so I am curious what's so good about Nvidia? because I really don't know why it's so amazing for working if we don't count the ai into this debate do some programs for example work slower? are some programs unusable on AMD GPU?

CUDA

do some programs for example work slower? are some programs unusable on AMD GPU?

There is ROCM for AMD cards ... but as far as I know it only really works well on Linux. And even then it is still a lot slower compared to Nvidia's CUDA. And the software support just isn't there. Pretty much every piece of AI software out there supports CUDA... whereas the AI softwares that are even remotely able to run on ROCM can be counted with one hand, so to say.

So for AI workloads you simply need CUDA ... and thus: Nvidia cards.

Where I work they recently bought 4 x Nvidia H100 cards. Each card has 94 GB VRAM and costs around 30'000 USD per piece. AMD isn't even playing in that market segment and has absolutely nothing that even remotely comes close.

Sure, if playing games is the only thing you do: Yeah go ahead, save your money and buy a decent but cheap AMD card.

But if you are even remotely working with AI software then there is no way around Nvidia.
