These AI data centre builds are packed with specific high power GPUs that are only useful for vector multiplication for AI, or mining cryptocurrency. To reduce overhead, they have kept non-GPU components to a minimum, because this lets you have more GPU processing per gigawatt. These data centres cannot be used for anything general purpose. General purpose computing needs CPUs, which they stocked as few of as possible.
