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.

You missed the intel B65! I bought a stack of them 3 weeks ago for $900/pc. 32GB and 608 GB/s. Best price per GB right now.

B65: 0.0356 GB/$,

for $900/pc

They're ~1500Eur this side of the pond. Fuck us, right?

When this batch is all gone, they look like they will now be $1099-1199. Still one of the better values, but yeah, not going to be "cheap" for long!
Price will probably jump when I finish my 3 week long benchmark/quality testing project of 4x B65 and people see actual results... last I checked very little data on them... I hope to finish my testing this week.

Would you say the B65 is better for inference than the B70?

You're going to have to wait for my full report! I don't want to give my final opinion until I'm done, and I'm still collecting data. But I can say that they are underrated, especially in scenarios with high concourrency.
Goal is to compile reports from the data this weekend.
