Benchmarks: PCmark Vantage, ScienceMark

The previous AMD Phenom II X4 processors fared well in the PCmark Vantage gaming test and the Phenom II X4 955 is no different, though it did fail to outperform the Phenom II X4 940.

While the Phenom II X4 processors were able to beat out the Core 2 Quad Q9650 in this test, the elusive Core i7 920 still remained a problem.

The PCmark Vantage communications test was quite different, the results are all over the place here. The AMD Phenom II X4 955 was faster than the Core i7 940 when using DDR3-1333 memory, but slightly slower with the DDR2-1066 memory.

Once again we found that when paired with DDR3 memory the Phenom II X4 955 was 9% faster than the Phenom II X4 940.

ScienceMark is another test that does not favor the Core i7 processors greatly and as a result the AMD Phenom II X4 955 is only a fraction slower than the Intel Core i7 965 Extreme Edition. The X4 955 was also 13% faster than the previous AMD flagship, the Phenom II X4 940.
