The upgrade, which took about a year, consisted of outfitting the device with 18,688 Tesla K20x GPU modules from Nvidia to work synchronously with a sophisticated array of 560,640 AMD processors. With Titan registering at a record-breaking 17.50 petaflops on the Linpack scale, Sequoia, rated at 16.32 petaflops, is now relegated to second place. For clarification, a petaflop is measured as a thousand trillion floating point operations per second.
