floating point operations per second = flops
not really a hardware speed, but an operations speed. how supercomputers are judged on efficiency.
flops are compared on a wattage/calculations use ratio and a dollar/calculations ratio to.
teraflop = 1 trillion flops
a single flop is an operation/calculation of.....your developers choice i guess.
you cant get a proper megahertz reading from a multiprocessor machine (dual cores are not the same thing)(this is why they call them cells on the ps3)
so they start measuring in flops. but the ps3 is near 1000 times faster then the ps2. the video processing sure is faster, but not quite by that much.
university's were using ps3s to run calculations for them in labs. its just much cheaper then buying yourself more supercomputers
