Who the hell keeps buying nvidia? Stop it.
Nvidia is the only real option for AI work. Before Trump lifted the really restrictive ban on GPUs to china they had to smuggle in GPUs from the US, and if you're Joe Schmo the only GPUs you can really buy are gaming ones. That's why the 5090 has been selling so well despite it being 2k and not all that much better than the 4090 in gaming.
Also AMD has no high end GPUs, and Intel barely has a mid range GPU.
To be fair, AMD is trying as hard as they can to not be appealing there. They inexplicably participate in the VRAM cartel when… they have no incentive to.
What's the VRAM cartel story? Think I missed that.
Basically, consumer VRAM is dirt cheap, not too far from DDR5 in $/gigabyte. And high VRAM (especially 48GB+) cards are in high demand.
But Nvidia charges through the nose for the privilege of adding more VRAM to cards. See this, which is almost the same silicon as the 5090: https://www.amazon.com/Blackwell-Professional-Workstation-Simulation-Engineering/dp/B0F7Y644FQ
When the bill of materials is really only like $100-$200 more, at most. Nvidia can get away with this because everyone is clamoring for their top end cards
AMD, meanwhile, is kind of a laughing stock in the prosumer GPU space. No one's buying them for CAD. No one's buying them for compute, for sure... And yet they do the same thing as Nvidia: https://www.amazon.com/AMD-Professional-Workstation-Rendering-DisplaPortTM/dp/B0C5DK4R3G/
In other words, with a phone call to their OEMs like Asus and such, Lisa Su could lift the VRAM restrictions from their cards and say 'you're allowed to sell as much VRAM on a 7900 or 9000 series as you can make fit." They could pull the rug out from under Nvidia and charge a $100-$200 markup instead of a $3000-$7000 one.
...Yet they don't.
It makes no sense. They're maintaining an anticompetitive VRAM 'cartel' with Nvidia instead of trying to compete.
Intel has more of an excuse here, as they literally don't manufacture a GPU that can take more than 24GB VRAM, but AMD literally has none I can think of.
