PCIe Speed Test v0.1 CPU-GPU/GPU-CPU bandwidth test

[EniGmA1987]

That is kinda weird. Both Intel systems with an X2 get the GPU -> CPU speed WAY lower than AMD systems with X2s, yet higher than AMD single card setups. jcool had normal CPU -> GPU bandwidth, but nsegative has half the bandwidth of AMD users. The difference between jcool and nsegative is jcool has an i7 with QPI, and nsegative has older fsb tech. the fsb cant really be limiting his bandwidth that much could it? And either way, why do both Intel based computers with 4870X2s have such low GPU -> CPU bandwidth compared to AMD?


EDIT: ya if you look at the guys with fsb based systems in the Intel section, they have more bandwidth than the AMD guys here with their HTT. So FSB definitely isnt a limiting factor. And since HTT has more bandwidth than FSB, something else is limiting the AMD system bandwidth.
