The big problems with wafer scale chips are that they are HUGE, insanely expensive, and use crazy amounts of power: not a problem for server farms. Cerebras’s chips cost a few million dollars and use something on the order of 20-25kW of power, but the advantage is that a single unit has roughly the same computing power as an entire conventional server room, while using far less energy and taking up only about 15 rack units to do so. Insane amount of space savings, under 10% the size of conventional servers.
