Heh, the fastest HPC cluster on the top 500 list is arm. Amusingly #2, #3, and #4 aren't x86-64 either. Number 5 is, but mainly because the xeons are handling I/O for the real heavy lifting on the matrix-2000 accelerators. The first pure x86-64 cluster is #8. So the performance story is changing quickly, and arm is just getting started.

Japan Captures TOP500 Crown with Arm-Powered Supercomputer https://top500.org/news/japan-captures-top500-crown-arm-powered-supercomputer/ https://top500.org/news/japan-captures-top500-crown-arm-powe... (June 2020) > The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. > Fugaku is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used in machine learning and AI applications, Fugaku’s peak performance is over 1,000 petaflops (1 exaflops). > The new system is installed at RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.
