Why are supercomputers measured in flops instead of hertz?

FLOPS (Floating Point Operations Per Second) give you an idea of how much a computing device can do in a second. Hertz is just frequency. While you can measure core speed in Hertz, that doesn't directly relate to the computational power of a piece of hardware. CPUs are actually slower now in terms of clock speed, but achieve more FLOPS due to architectural improvements.

Example: If you have a single core CPU running at 4GHz and you compare it to a Quadcore or a GPU at 2-3GHz the single core, the latter will beat the single core *if* the task is parallelizable.
