DIFFERENCE BETWEEN CORE I3, CORE I5, CORE I7...?? If you want a plain and simple answer, then generally speaking, Core i7s are better than Core i5s, which are in turn better than Core i3s. Nope, Core i7 does not have seven cores nor does Core i3 have three cores. The numbers are simply indicative of their relative processing powers Number of cores The more cores there are, the more tasks (known as threads) can be served at the same time. The lowest number of cores can be found in Core i3 CPUs, i.e., which have only two cores. Currently, all Core i3s are dual-core processors. Currently all Core i5 processors, except for the i5-661, are quad cores in Australia. The Core i5-661 is only a dual-core processor with a clockspeed of 3.33 GHz. Remember that all Core i3s are also dual cores. Furthermore, the i3-560 is also 3.33GHz, yet a lot cheaper. Sounds like it might be a better buy than the i5. What gives? At this point, I’d like to grab the opportunity to illustrate how a number of factors affect the overall processing power of a CPU and determine whether it should be considered an i3, an i5, or an i7.Even if the i5-661 normally runs at the same clockspeed as Core i3-560, and even if they all have the same number of cores, the i5-661 benefits from a technology known as Turbo Boost. Bullet points ............... -> Core i3: * Entry level processor. * 2-4 Cores * 4 Threads * Hyper-Threading (efficient use of processor resources) * 3-4 MB Cache * 32 nm Silicon (less heat and energy) -> Core i5: * Mid range processor. * 2-4 Cores * 4 Threads * Turbo Mode (turn off core if not used) * Hyper-Threading (efficient use of processor resources) * 3-8 MB Cache * 32-45 nm Silicon (less heat and energy) -> Core i7: * High end processor. * 4 Cores * 8 Threads * Turbo Mode (turn off core if not used) * Hyper-Threading (efficient use of processor resources) * 4-8 MB Cache * 32-45 nm Silicon (less heat and energy)
