Our final two benchmarks are somewhat synthetic tests that Valve offered us to give us a preview of the impact of multi-core CPUs in future games. We've talked about both of these tests in our Valve Hardware Day 2006 article if you're interested in learning more about them and what they do.
Valve Software's Gabe Newell talked about the importance of quad core processors when he introduced us to these benchmarks. He stated that all future PCs at Valve Software would have at least four processor cores, due to the improved productivity offered. This type of performance improvement is once again the type of stuff you don't see in a lot of applications, but if you do a lot of content creation work that can leverage multi-core CPUs the performance improvements can be substantial. The 20% overclock on the Gateway system improves performance by 16% to 17% in these benchmarks, which isn't bad considering it only adds $100 to the cost of the system relative to a stock QX6700. Relative to an X6800, the overclocked QX6700 is almost twice as fast!
