If AMD cards were half the price of Nvidia ones then sure, this would happen. The 4090 can be had for ~$1600USD and the RX 7900 for about ~$1000USD. A significant discount, however the RX 7900 is about 3/4ths as powerful as the 4090, which puts it more in the class as a 4080, which costs about as much.
As a small budget research/grad student, if the price difference isn't that big, why waste the time porting torch to it?
- dauertewigkeit 3y agoNah, price isn't going to be a motivating factor. If AMD came up with a card that had 3x the VRAM of the latest NVIDIA offering there would be research groups who would be interested because loads of models are hardware bottlenecked.

- comte7092 3y agoOf course cost is a motivating factor. The very nature of GPUs implies that they are optimized for parallelizable workloads. If I can split my training across 3x the chips at 1/10th the cost for each chip, why wouldn’t I do that?
- latchkey 3y agoYou're thinking consumer. MI250 cards are less than half the price of H100, and more importantly, you can buy them today.
