Apparently data centers routinely burn through water at a rate of about 1.9 liters per KWh of energy spent computing. Yet I can 🎮 HARDCORE GAME 🎮 on my hundreds-of-watts GPU for several hours, without pouring any of my Mountain Dew into the computer? Even if the PC is water cooled, the water cooling water stays in the computer, except for exceptional circumstances.
Meanwhile, water comes out of my A/C unit and makes the ground around it all muddy.
How am I running circles around the water efficiency of a huge AI data center, with an overall negative water consumption?
because it’s cheap, easy, compact, well understood, and makes numbers look good. number in question is ratio of energy used by entire facility to energy used by silicon only (i forgor how it’s called). alternative is dissipating heat from radiators, but this makes this number like 3. evaporative cooling makes this number closer to 1.2
