That K40 setup requires a 1 kW power supply. With energy prices up, that can get pretty expensive in the long run. I suspect a newer Nvidia chip manufactured on a more efficient semiconductor process will deliver the same performance for a fraction of the power consumption. This is often a problem with old hardware. The power efficiency gains from improvements between chip process nodes are so fundamental that it’s hard for older chips to compete in total cost of ownership.
