One AI Rack Uses 142 kW. How Do You Cool It?
What the video covers
One NVIDIA GB300 NVL72 rack draws up to 142 kW. AMD lists 1,400 W for a single MI355X chip, against up to 700 W for NVIDIA's H100. Air cannot move that much heat, so cooling goes liquid. Using NVIDIA's DSX design rule, a 142 kW rack needs about 213 litres of coolant a minute. That is a worked example on our site, not a vendor figure.
