China
China's slice of the world's 85.85 ZFLOP/s of installed computing power — its datacenter silicon apportioned from published AI-compute shares, its personal silicon from population and device intensity, and both marked to the daily headline. Per person it holds 1.0x the world average.

Two keys, blended by their real weight in the headline. About 37% of the world's compute is datacenter and industrial silicon, which is extraordinarily concentrated and apportioned from published AI-compute shares. The other 63% is personal — phones, gaming GPUs, PCs, consoles — which follows people, apportioned by population weighted for device intensity. China comes out at 16.41% of the world total, or 14.09 zettaFLOP/s.
Note: this is an apportionment, not a measurement. Nobody publishes a per-country census of installed FLOP/s, and this is the most approximate part of the site. See the methodology for both keys and the assumptions behind them.
