Yeah, these GPUs became less appealing after the prices of 30-series GPUs have dropped. The price of SXM cards are still somewhat unbeatable though if you have a compatible server motherboard [1]. Nvidia P100s are being sold for as low as $100 each, there are similar savings for the Nvidia V100s. But yeah, a saving around $100 to $200 is not really worthwhile...
Another curious contender is the decommissioned Nvidia CMP series GPUs from miners. For example, the Nvidia CMP 170HX basically uses the same Nvidia A100 PCB with its features downsized or disabled (8 GB VRAM, halved shaders, etc). But interestingly, it seems to preserve the full 1500 GB/s memory bandwidth, making it potentially an interesting card for running memory-bound simulations.
[1] Prices are so low exactly because most people don't. SXM-to-PCIe adapters also exist which cost $100-$200 - nearly as much as you have saved. It should be trivial to reverse-engineer the pinout to make a free and open source version.
- LoganDark 3y agoIs it possible to take something like a CMP 170HX and do board-level work to add more memory chips? Or are they not connected to silicon?
- segfaultbuserr 3y agoI don't believe it's possible. The HBM2e chips are integrated onto the package of the GPU die, making them impossible to remove or modify in a non-destructive manner.
- brucethemoose2 3y agoI didn't know the CMP had full bandwidth. that would be a an excellent card for smallish networks (like stable diffusion, GANs, audio networks) ...But it doesn't seem to be cheap. Not really worth it over a 4090 for the same price.
- segfaultbuserr 3y agoIt seems that the CMP 170HX is being sold for $500 +/- $100 on the flea markets in China as closed mining farms are dumping any remaining inventory. Not sure if the prices are real, I'm currently trying to purchase some.
- segfaultbuserr 3y agoI can confirm that the price is real ;-)
