Which CPU runs Battlefield 2142 faster, AMD or Intel? Does a larger L2 cache really play a huge role in performance, or is it minor? We've rounded up the latest CPUs from AMD and Intel to answer these questions. See the results inside! To see how much of an impact L2 cache size has on performance, we?re pitting a Core 2 Extreme CPU that?s been underclocked to the Core 2 Duo E6400?s stock speed of 2.13GHz, as well as the X2 5200+ against the 5000+. At 800x600, the underclocked 4MB cache Core 2 Extreme chip ran 6% faster than the 2MB Core 2 Duo running at the same speed, so the extra cache definitely gives the Extreme a nice boost in Battlefield 2142, we saw the same occur for the Athlon 64 X2s, with the 5200+ running 5% faster thanks to its larger 1MB L2 cache.
