Each of these GPUs pull up to a kilowatt of power. The average commercial power cost is 13.4 ¢/kWh. That means running a single H100 full tilt 24/7 is a power operationing cost of $1,100 per card per year.

In three years the current generation of GPUs will be 50% or more faster. In six years your talking more than 100% faster. For the same energy costs.

If you're running a GPU data center on six year old GPUs, your cost to operate per sellable unit of work is double the cost of a competitor.
