SiSoft Sandra 2009 - Memory	Source: Sandra

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher bandwidth and lower latencies are best.

Memory performance has always been Intel's game, and the Athlon II X4 635 doesn't change that. Intel's Core i7 920 dominates these benchmark results, followed by the Core i5 750. AMD's processors trail in almost every test here.

Again, purely synthetic performance scores stay here. Intel dominates the memory portion of Sandra while the AMD systems do well, but aren't able to quite match the Core i5 and Core i7.
