Hi All I recently run a BenchmarkReport[] on my machine at work (Core 2 duo @2.66GHz, 4GB DDR2 RAM on windows xp 32 bit, NVIDIA graphs with 512MB). I wanted to make a comparison with my laptop, a much newer macbook pro (Core 2 @2.53, 4GB DDR3 RAM, NVIDIA 256 on Snow leopard). Though my desktop machine is slightly faster, it was running a 32 bit operating system, so I was expecting the mac to be at least marginally better. My surprise was when I got an overall of 2.96 with windows XP against 2.41 for the Mac (after 4 tests, mean time 35.73 mac x 29.16 windows) Individually the biggest difference appears to be on test 5 - Elementary functions - (2.52 Windows x 7.38 on a Mac). The mac was better at tests 8,7 and 6 (Matrix arithmetic, Large Integer multiplication and gamma function) with scores of respectively 3.69 x 2.86, 0.94 x 0.53 and 0.53 x 0.29, which makes sense. Is this expected? or am I doing something wrong on my 64 bit operating system machine? Another question is whether Mathematica will take advantage of OpenCL technology (or any GPGPU technology as windows 7 is promising) Best
