It's just not economical to run these given how power inefficient they are in comparison to modern processors.

This uses 1.7MW, or $6k per day of electricity. It would take only about four months of powering this thing to pay for 2000 5950X processors. Those would have a similar compute power to the 8000 Xeons in Cheyenne but they'd cost 1/4 the power consumption.

If you can get 1.7MW service, then you are paying utility rates, or around 100-150 per MWh, or as you quoted 4-6k per day. In Seattle, running this off peak would cost one about 104$/hr before the other fees.

I would be neat if a subset of this could be made operational and booted once in awhile a computer history museum. I agree that it doesn't make sense to actually run it.
