"Dark GPUs" at Amazon show the limits of the AI buildout: chips are easy to buy, power is not
Amazon is reportedly purchasing billions of dollars' worth of Nvidia GPUs monthly, despite power constraints at some AWS facilities. The company is storing unpowered hardware in warehouses, a practice called 'dark GPUs.' Amazon's free cash flow turned negative in Q2, with $220B in expected capital expenditures this year. The company defends the strategy, citing AI's long-term potential.
