quote:August 18th, 2005 -- Maybe memory latency speed makes a difference after all. I was doing some testing on two different G5/2.5GHz Power Macs. They are configured identical in every way (8GB RAM, GeForce 6800 Ultra). In fact, they have identical Raptor 10K boot drives in the top factory slot with contents of one cloned to the other. When I ran my Motion 2 "render RAM preview" test, one system ran 8% faster than the other. Why? Well, there is one difference. The faster G5 had CAS 2 memory and the other one had CAS 3.
