标题: intel这么悲催？

CalculationThe raw performance of integrated GPU, in single-precision FLOPS, can be calculated as follows: EU * 4 [dual-issue x 2 SP] * 2 [multiply + accumulate] * clock speed. For example, the HD Graphics 3000 is rated at 125 GFLOPS,[55] which is consistent with the formula (12 * 4 * 2 * 1,300 MHz).
HD3000 才125GFLOPS，HD2000大约52GFLOPS，HD4000差不多168GFLOPS。
对比：
9500 GT 134GFLOPS，9600 GT 300GFLOPS，GT 220 200GFLOPS, GT640 700GFLOPS
HD 6410D(A4) 192GFLOPS，HD 6530D(A6) 284GFLOPS，HD 6550D(A8) 480GFLOPS, GT640 700GFLOPS

ps: HD4200(785G) 40GFLOPS
