The quoted figure for broadwell is a 40% graphics performance improvement over haswell. However this little titbit has been floating around the internet : "At 1GHz,broadwell is projected to have 2 TFLOP of shader performance. Haswell's 40EU (160 ALUs) GT3/GT3e, by comparison, has 832 GFLOP of shader performance (SP) at 1.3GHz." http://hardware.forumsee.com/a/m/s/p12-29521-0104887--broadwell-gt4-info.html That seems pretty amazing. Not sure though exactly how to read this. Does shader performance = total performance? i.e 2tflops vs 832gflops = +240% . Is this a 240% performance improvement or are there other areas of the GPU for tessellation, physics etc that could effect frame rate?
