Memory Bandwidth Performance
The memory bandwidth figures are not at all surprising considering that the memory controller is located in the processor and not the chipset. Therefore the AMD 890GX has no real way of influencing memory performance. Still it is important to measure the performance here to make sure everything is working properly as these results will have a real impact on other performance tests such as gaming.
Something worth noting is that the memory bandwidth performance of the Phenom II X4 965 processor is considerably weaker than the Core i5 750. The Phenom II X4 965 processors L2 cache performance is also weaker, particularly when writing data as the Core i5 750 was 19% faster here.
