More than half of all server CPUs are AMD. They absolutely domininate in HPC and servers (and have for years, now).

2026Q2 numbers show Intel falling quickly but still in the mid-60% to 70% in every market: https://www.tomshardware.com/pc-components/cpus/desktop-cpu-...

AMD was at over 46% of the "server" market 1Q2026.

Intel isn't even condered a player in HPC anymore. 147 of TOP 500 is AMD (it's really custom chips, which AMD also does with it's Xilinx and Instinct divisions, and nVidia that are chewing up the Intels)

AMD has practically abandoned their HPC-focused Threadripper series too, leaving the market segmentunmet by anyone. The supercomputers in the Top 500 listing only account for a fraction of CPU sales, where they mostly serve to feed accelerators.
