Capex != Opex
Your are measuring two very different things.
And you are only considering electricity bills for the GPU. Higher TDP also means more heat which means more cooling.
It's not really easy to make an off hand comment about costs. A 30-40% decreaae in electricity usage and heat output for a fleet of GPUs definitely makes a massive difference to your opex bottom line.

- fc417fc802 2mo agoThe datacenter will already have been built with an explicit cooling budget. Moving 1 watt of heat requires substantially less than 1 watt to do the work. So you've got a constant multiplier against something like a 9% annual failure rate and an order of magnitude difference in cost.
