Using EVEREST Ultimate Edition we look at the memory bandwidth performance of these processors. The results differ from those reported by SiSoftware Sandra, as we test both read and write performance individually. Here the Phenom II X4 processors show considerably better write performance when compared to the Core 2 series, while their read performance is slightly lower.

As expected the Phenom II X4 965 was slightly faster than the 955 in the CINEBENCH R10 multi-CPU rendering test, providing just 2% more performance.

All the Phenom II X4 processors perform poorly in the CINEBENCH R10 OpenGL rendering test as evidenced here.
