My buddy and I just did Xbench tests on our laptops... His is a 2010 15" i7 with 4GB of RAM and a 128GB Apple SSD. Mine is a 2009 15" 2.66GHz C2D with 8GB of RAM and a 320GB 5400rpm HDD. His results when we run JUST the XBench for memory was almost twice what mine was! Same bus speed and everything... Why would this be? Does the processor or SDD/HDD effect it as well for some reason?
Got a tip for us?

Why is 8GB slower than 4GB?

Xbench is in dire need up an update. Its over 4 years old now and I doubt its really that accurate with modern systems being so different than they were back then. More than likely its a fluke, or since the program isn't 64 bit its not addressing all your RAM properly.
You are completely forgetting that the i series has a different memory controller than the core 2 duo. You can't compare the two.
4GB mmeory is the max that can be addressed by 32bits of space, whereas 8 can only be fully utilized by a 64-bit addressing system.
