5090 Price Leak

If you knew what our electric bills were you'd understand. It's a value when you can run one expensive car instead of two half expensive cards. And trying to cure diseases isn't for everybody.

This, exactly (for me at least). I'm more worried about ongoing operational costs than than acquisition costs. I get we each have our own constraints and preferences so others' may feel differently than I do, but when your power pill is equal or higher than your mortgage you think about these things. At this point I'm looking at liquid cooling my GPUs and feeding the heated water into a radiator outside (summer) or one or more in the house (winter). But that's my thinking at any rate.

Well, since the conversation came up about efficiency, I'd show you the other end of the spectrum. I have 4 servers, 2 GPUs (L40S) each consuming 1645 watts per server. That's 6580 watts for ~180 million PPD. My calculations are that these are twice as inefficient as a few rigs with 4090s. They put out quite a bit of points but at a very high cost.

6580 watts!?

My 4090s peak out at around 425 watts. They seem to average around 390 watts. They (combined) have been averaging around 50,000,000 PPD for a while now.

Well, let me clarify. It's about 822 watts per GPU for the L40S.

There you go 1 L40S
