These set of benchmarks still have some bogosity behind them. There should be no difference in the copy throughput since that is GPU bound using identical operations, but most of the rest can be explained with the choice of unity wm and using ubuntu. Comparing results from a mobile GT2 device (a i7-3720qm) with this article a deskop GT1 chipset, http://openbenchmarking.org/result/1...SU-1209034SU66, we get the impression that the system under test underperformed significantly.
