The new quad-core series consists of the Core 2 Quad Q6600 and the Core 2 Extreme QX6700. Both feature a dual 4MB L2 cache, operate on a 1066MHz FSB, and have a thermal output of 130 watts. The term Core 2 Duo refers to the 64-bit dual core processors belonging to the Intel Core 2 family. This CPU is considered to be the direct descendant of the Core Duo. In technical terms, the dual cores in this CPU are designed on the Intel Pentium M microarchitecture and they work in parallel. These cores typically have a much shorter pipeline AMD Athlon 64 X2 Dual Core 4000+ vs Intel Core2 Duo E6400 @ 2.13GHz The values for the CPUs below are determined from thousands of PerformanceTest benchmark results and are updated daily. The first section will show basic information for each CPU selected. Intel Pentium E5400 @ 2.70GHz vs Intel Core2 Duo E8400. 962 (-19.5%) Intel Pentium E5300 @ 2.60GHz vs Intel Core2 Duo E8400. 925 (-22.5%) Intel Core2 Duo E8600 @ 3.33GHz vs Intel Core2 Duo E8400. 1,368 (+14.5%) Intel Core2 Duo E8200 @ 2.66GHz vs Intel Core2 Duo E8400. Core 2 Extreme vs. Core 2 Duo. Previously Intel had differentiated its "Extreme" line of processors by giving them larger caches, a faster FSB, Hyper Threading support, and/or higher clock speeds Xt8qz.
