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.

Like all of AMD's processors, the AMD Phenom II X6 1090T has difficult keeping up with Intel's Core i5/Core i7 processors when it comes to memory performance. Whether TurboCore is on or off, the AMD Phenom II X6 1090T ends up having lower memory bandwidth but higher latencies in this theoretical test.
