I'm skeptical whether the TrueCrypt encryption benchmark accurately measures the performance of the Intel processors with AES-NI instructions. I work with Bitlocker-encrypted desktops with Core i5-650s and one with X3570 (similar to the i7-960). Both the i5-650 and X3570 have the same baseline and turbo frequencies. Subjectively, the i5-650 boots, resumes from hibnernation, and opens app's a bit faster in spite of the X3570 having double the cache and double the cores. On Everest the i5-650 performance is far ahead of the X3570 on the AES test (and as far behind the X3570 on the CPU hash test, as expected). On Vantage PCMark (on my encrypted desktops) the i5-650 is faster than the X3570 on the communications and application launching tests where encryption acceleration should show itself. So, as the previous poster wondered, what does the TrueCrypt benchmark measure?
