    Assisted Solution

    The "T" stands for threads for instance 2c/4t  It relates to multi-threading. It means 2 cores, 4 threads. Each core can work on two tasks at the same time.

    Assisted Solution

    4 X 1.2ghz = closest equivalent Intel® Pentium® G620 2.60 GHz, 3M Cache, Dual Core/2T
    8 X 1.2ghz = closest equivalent Intel® Core® I3-2100 3.10GHz, 3M cache, Dual Core/4T
    LVL 70

    Accepted Solution

    As noted above, "C" and "T" refer to cores and threads -- which will be different for hyperthreaded CPUs.

    For example, 2C/4T means a dual core CPU that has two central processing units (cores), but supports hyperthreading, so it "looks" like 4 processors to the OS.    Note that it's not technically true that for hyperthreaded cores "... each core can work on two tasks at the same time .." => hyperthreading doesn't add another processing unit;  it adds another complete set of processor registers so context switching is MUCH faster than traditional multi-tasking allows.    It does indeed "look" like another core to the OS ... but only one of the 2 threads in each core is active at any given instant of time.

    None of the processors listed are 8-core, so there's no direct 8 x 1.2GHz equivalent.   Any of the quad-core CPUs with a clock speed of at least double that (2.4GHz) would have roughly the same processing power -- and if hyperthreaded would "look" like 8 cores to the OS.    You can look up the exact specs for any of these CPUs on Intel's processor specification site:

    ... or you can compare the CPU "horsepower" by looking up the CPUMark on PassMark's excellent site:
