FX-8370 – Win Task Manager shows 4 p. cores and 8 l. cores RRS feed

  • Question

  • Windows Task Manager show me that AMD FX-8370 runs with 4 p. cores and 8 l. cores. I thought that it should run on 8 p. cores but another diagnostics shows just 8 cores.

    What is the problem?

    Term “Jádra” means cores. Term “Logické procesory” means logical cores.

  • there seems to be some debate about the number of cores in the Bulldozer architecture:
    AMD sued: Number of Bulldozer cores in its chips is a lie, allegedly
    while I did not find out what the result of the lawsuit was, Wikipedia says:
    "Bulldozer introduced a "Clustered MultiThreading" (CMT) where some parts of the processor are shared between two threads and some parts are unique for each thread."

    Sounds like what Intel calls Hyperthreading to me. So Windows is right to treat this a 4 Cores, 8 threads.
