All Core i3's, i5's, and i7's are hyper threading. This means that a Dual-core i7 can follow up to Four threads simultaneously, while a Quad-core can follow up to Eight. For a power user, from which it sounds like you are, a Quad-core is the way to go. //Dual-core i7 can follow up to Four threads simultaneously, while a Quad-core can follow up Penryn is the code name of a processor from Intel that is sold in varying configurations as Core 2 Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron. During development, Penryn was the Intel code name for the 2007/2008 "Tick" of Intel's Tick-Tock cycle which shrunk Merom to 45 nanometers as CPUID model 23. The term "Penryn" is sometimes used Wolfdale is the code name for a processor from Intel that is sold in varying configurations as Core 2 Duo, Celeron, Pentium and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. This replaced the Conroe processor with Wolfdale . Turbo Boost. Core i3 processors do not support "Turbo Boost". Core i5 processors support dynamic overclocking of the CPU (Turbo Boost) to enhance performance. Integrated GPU (graphics processor) All models of Core i3 have an integrated GPU. Core i5-6xx processors have an integrated GPU; others do not. CPU clock rate. 0. 65W. 65W. Lower is better. - Intel Core 2 Duo E6600 - Intel Pentium E6500. Please see the Specifications section below for detailed side by side comparison of Intel E6600 vs Pentium E6500 specs. The CPUIDs section provides even more detailed comparison of low level features of both CPUs. The Intel Core2 Duo E8400 has 2 cores with 2 threads and clocks with a maximum frequency of 3.00 GHz. Up to 16 GB of memory is supported in 2 memory channels. The Intel Core2 Duo E8400 was released in Q1/2008. The Intel Core 2 Quad Q8400 has 4 cores with 4 threads and clocks with a maximum frequency of 2.66 GHz. .
