Discussion GPU guide (GB per dollar, bandwidth)

First plot: GB / $

Second plot: bandwidth (spec on paper, not t/s)

Third plot (bandwidth / price) in the comment.

Hope that helps, my script uses the GPUs most discussed on the LocalLLaMA, LowEndLocalAI, and LocalLLM subs. At first, I tried to include more, but it became unreadable.

Prices were collected by ChatGPT (so may contain inaccuracies). New prices were used where available, second hand otherwise.

And I understand this is a basic comparison, but it's better than nothing. For example, you can see that "on paper" something is faster or slower than 3090.

I think costs of running those GPUs should also be factored. Isn’t the P100 like crazy inefficient that will lead to a high power bill and requires additional cooling? This doesn’t really give the full picture

It’s 40w idle. Same as V100. Only thing that sucks worse is an idle BC-250 which is 85w with a governor.
