Server CPUs
Xeon, EPYC, Graviton and the rest — the silicon that actually runs the internet. Tiny in FLOP/s next to a GPU rack and indispensable anyway: databases, networking and orchestration are latency problems, not throughput problems.
Server CPUs over time
Installed compute in zettaFLOP/s, log scale, 2008 → present. A straight line on this axis means steady exponential growth; the slope is the doubling rate. History before the 2026 anchor is reconstructed — see the methodology.
~120M active servers x ~2.5 TFLOP/s dense FP16 (AVX-512 / AMX / SVE across sockets).
~120 million servers. Intel AMX and Arm SVE2 give modern sockets real matrix throughput; most of the installed base predates them.
Overlap treatment: Host CPUs in accelerated nodes are counted here; their attached GPUs are counted in the AI lines. The two are separate silicon.
Growth: compounding at 1.15× a year (59.5-month doubling) between published vintages.
