Next while we are working with the AIDA64 EE program, I used this program to also do memory benchmarks, here are the memory bandwidth benchmarks:
Now remember that at 2.8 GHz the 2600K is at 1066 MHz memory. I also included 2600K at 2.8 GHz with overclocked memory to show the difference CPU frequency makes to memory bandwidth. As you can see it does improve memory bandwidth some. We are using the i7930 in dual channel configuration, triple channel should do a bit better, but I wanted to compare the systems on an even plane. As you can tell memory bandwidth is an area that Sandy Bridge performs excellent in without a doubt, just look at how even when down clocked it matches the i7930 at 4.2 GHz and 1600MHz.
Here is the last AIDA64 EE benchmark, it is memory latency:
As you can see again, CPU frequency has a great impact on latency with SandyBridge, the fact that I used/set cas 9 even when SPD was lower was so that I could get nice base line readings.
