We saw similarly small increases in our 3DMark 11 and 3DMark Vantage gaming tests (9,332 to 9,591 and 32,129 to 33,382, respectively) and comprehensive Geekbench benchmark (13,083 to 13,586), as well as throughout our more probing AIDA64 and SiSoftware Sandra processor tests.

Certainly where the multithreading counts those extra two Nehalem cores make themselves known, but the second-gen Core CPU can be overclocked to duck below 30 seconds in Cinebench too.

The rendering performance in Cinebench is something to behold; watching those twelve threads zip across the screen in a dance of mathematics is almost hypnotic.
