I have loads of examples from my Benching to back this up. They are countless. I just dont have time to bench inefficient systems and then efficient ones to back up this stuff. This Cinebench example I am presuming is all none tuned XMP. Tuning thirds alone can make a large difference to scores. Here they are looking at frequency and primary timings not anything else = rubbish. How about DDR2133 C6 vs 1600C6 and then see.
