Memory tests and HEXUS.PiFast
A lot of chips in this line-up. The colours represent the varying physical cores for each CPU. Bear in mind that the only the Intel Core i7 875K and Core i5 655K are overclocked, to 4.15GHz and 4.42GHz, respectively.
The three 900-series chips use a triple-channel memory-controller and therefore take the lead here. The 875K does pretty well.
Having graphics on the same package, but not on the same silicon, means that the Core i5 chips have to traverse the IGP in order to access main memory. This is why the Core i5 655K doesn't do as well here.
The single-threaded HEXUS.PiFast test loves frequency above all else. The 655K's 4.42GHz clocking makes short work of the test, coming in with the fastest time.
