At first glance, the new AMD solution seems to be winning in 3D games. Phenom II X4 920 working at 3.72 GHz outperforms its major Core 2 Quad Q8300 competitor in every single test we used. However, it most likely happens due to seriously cut-down cache-memory of the Intel CPU. That is why when we compare the performance of our Phenom II X4 920 against that of an overclocked Core 2 Quad Q6600, the outcome is no longer in AMD’s favor: even though Q6600 processor belongs to the previous generation, it features an 8MB L2 cache.
Overall, we are not really talking about any serious performance differences. Overclocked Phenom II X4 looks quite well and demonstrates very good performance. Nevertheless, I have to say that overclocking a $200 quad-core processor will not provide the users with the same performance that they could get from higher-end more expensive CPUs, even working at their nominal speeds.
