[wlug] World’s Fastest Computer Is ARM

Looking at the June Top500 list <https://top500.org/lists/top500/list/2020/06/>, the current number 1, Japan’s Fugaku, uses over 7 million A64FX cores and close to 5 petabytes of RAM. Numbers 2 and 3 are based on IBM’s POWER architecture, while number 4 is a Chinese RISC-based machine, which might have some resemblance to the DEC Alpha <https://en.wikipedia.org/wiki/Sunway_(processor)>, or MIPS, or not. It’s not until 5th place does x86 make an appearance.
