In europe that situation will be wildly different. Here in germany you won’t get under 0.50$/kWh (edit: more like .30 now) so it’s more like 500 to 800 hours
Edit 2: wow, thanks for the hint! I just halved my prices by switching
True, but that’s still on the order of time that you may never reach the price difference in the lifespan of the GPU.
I switched to a half hourly tracker earlier this year. So it’s like 10-15p/kWh (and sometimes as low as negative so they pay you to use the electricity) and jumping to 30-40p between 4pm and 7pm.
As someone working from home with pretty much constant electricity use all day, it’s saved me tons.
