Page 1 of 3   All Intel Core i7 CPUs (LGA 1156 and LGA1366) support Hyper Threading technology. Problem is that just few applications really know how to use this technology efficiently. In addition, Core i7 CPUs for 1366 socket have triple channel memory controller and huge bandwidth, while double channel memory controller and slightly less memory bandwidth have CPUs for 1156 socket. Since there was demand for CPUs that are faster than “good old” Core2Quad models, and, on the other hand not too much slower than Core i7 models, but at the same time much cheaper, Intel decided to satisfy these demands with Core i5 CPU.
Code name for Core i5 is Lynnfield and it is made in 45nm manufacturing process. Core i5 does not support Hyper Threading, which means that Task Manager in Windows will show real number of cores present in CPU. Most users won’t notice any significant difference in performance levels compared to similar CPUs with Hyper Threading. Good news is that this CPU has integrated memory and PCIe controller, which will provide great performance levels.
Core i5 750 operates at 2.66GHz and has 8MB L3 cache memory while its thermal dissipation should be around 95W (when not overclocked). It has two-channel memory controller with support for DDR3 RAM standard (800/1066/1333). Most of technologies are supported by this CPU (Intel Virtualization Technology, Enhanced Halt State C1E, Intel Demand Based Switching, Intel Turbo Boost Technology etc) while some are missing (Intel Hyper Threading, Intel Thermal Monitor 2 and Intel Trusted Execution Technology).
