Another example: Whether you’re mining bitcoin or running an AI cluster, machines must be cooled to avoid overheating – but the optimal cooling method will depend on the application, Cann said. Most bitcoin rigs are cooled by fans or by being submerged in a pool of dielectric fluid, which comes at little cost. The GPUs used for AI, on the other hand, require some form of air conditioning, or to pass fluid over the machine’s silicon chip – two methods that consume large amounts of energy. Other differences emerge when you look at the kind of hard drives used for AI fleets compared to bitcoin mining operations, or the amount of fiber and connectivity that is needed for each site.
