10989651.89 * $0.332 = $3,648,564.4 (about 87 BTC when i write this post)
Using my program numbers look more optimistic:
on vast.ai single rtx3090 costs 0.414, single rtx3080Ti costs 0.314. I think their performance is similar (maybe paying 25% less for 3080Ti makes sense, I do not know now).
On rtx3090 I measured performance around 3450Mkeys. It gives 58^11/3450000000/3600s = 2011807 hours => $832 888
According to Wikipedia, RTX 3080 Ti and RTX 3090 have very similar TFLOPs. So it should be cheaper to rent 3080 Ti where you could reduce the cost up to 25% (rough estimation).
| Half | Single | Double
RTX 3080 Ti | 27.955 (34.100) | 27.955 (34.100) | 0.437 (0.533)
RTX 3090 | 29.284 (35.581) | 29.284 (35.581) | 0.458 (0.556)
Anyway, the question is where to find - let's say - 6000 cards to solve it in +-2 weeks...
I expect you'll need to register to many GPU renting marketplace and VPS provider. But VPS provider usually offer enterprise GPU instead (such as A5000) which is far more expensive.
