For those not in the know, Frontier has 1.194 Exaflop/s (EFlop/s) of performance, easily fending off a half-scale 585.34 Petaflop/s (PFlop/s) submission from the Argonne National Laboratory’s Intel-powered Aurora supercomputer.

Argonne only uses half of its Aurora system for now but still managed to kick Japan’s Fugaku out of second place. Intel and Argonne are still working to bring Arora entirely online. As such, the Aurora submission represented 10,624 Intel CPUs and 31,874 Intel GPUs working in concert to deliver 585.34 PFlop/s at 24.69 megawatts (MW) of energy.

More embarrassing for Intel is that AMD’s Frontier consumes 22.70 MW of energy, a complete supercomputer for half the juice of the Aurora system.

Intel made inroads with 20 new supercomputers based on its Sapphire Rapids CPUs entering the list, but AMD’s EPYC continues to take over the Top500 as it now powers 140 systems on the list -- a 39 per cent year-over-year increase.
