Google Colab free used to offer 4 different models of Tesla. Current state of the art gear will eventually be resold-used-for-a-fraction-of-list.

Or buy a used rack style server with a row of blowers included. And either way, deal with limited driver availability. (Few Linux distros, no Windows.)

How does the performance/$ compare to current gen / next gen consumer cards? I am not sure it will outperform $1000 7900 XTX

With colab (free or paid), you're at the mercy of google for what card you get and how long you get it for. Not really worth getting excited about.

I am not sure how much cheaper these will be in used market, but yes, if you can get some of these cheap enough, it _might_ be worth it. "Might", because, by the time they become cheap enough, the latest gen consumer card might still offer better performance/$

No purchase cost, and no utility cost, but higher end user time cost, is a tradeoff that may be very palatable for some with limited funds or cooling capacity. Plus it offers a try-before-you-buy experience. I'm routinely running 7 Colab free tabs, getting usually a 3.5 hour GPU & CPU session & multiple CPU-only sessions per day on each tab, for a combined throughput of ~ >1. T4 24/7. It's not for everyone.

Likely it will. While the RX 7900 XTX is overall a much faster card (a MI60 is based on the same architecture as the Radeon VII) the 1/16 FP64/FP32 ratio on the RX 7900 XTX slows it down for gpuOwl.

Is the FP32/FP64 Ratio really 1/16?!?!

3.848 TFLOPS (1:16)

i think PRP much faster than my RTX4090

RTX4090 is 1,290 GFLOPS (1:64)
