Volvo’s “Drive Me” project, toward the goal of making fatalities a thing of the past in its cars by 2020, involves a super computer from Nvidia Corp. Volvo’s decision to use the computer from a company best known for building high-powered graphics cars for video gaming, reveals how much processing power may be necessary to guide self-driving cars. Nvidia’s water-cooled, lunchbox-sized supercomputer, packs the power of 150 MacBook Pro laptops, per the company.
