You're confusing consumption with innovation. The Chinese are now the #2 world consumer of supercomputing technology, as measured in total computing power. This is largely due to their possession of the fastest supercomputer in the world, Tianhe-2, which is capable of 33.86 petaflops/second. The next fastest computer has slightly more than half of that capacity.

The Tianhe-2 runs the Intel Xeon Phi processor. Overall, Intel (based in Santa Clara, CA) processors run 82.4% of the top 500 supercomputers. Other common providers are Cray (Seattle, WA) and IBM (Armonk, NY).
