Changing thread configuration on i5 650

Last response: in CPUs
Share

Hello,

Is it possible to have the i5 650 work with one thread to a core (totaling two threads), instead of working with two threads to a core (totaling four threads)?

I need this since I am working with a program that can use only one thread and I want it to utilize 50% of the CPU capabilites (one full core) and currently it is only using 25% of the CPU which is 100% of one thread.

Thanks

It probably won't make much of a performance difference (there are a few programs that do perform better with hyper-threading off). Odds are the program is already using the "real" core and not the hyper-threaded core. Hyper-threading uses unutilized portions of the CPU to perform other operations, disabling it is unlikely to bring about a gain in performance, instead of being able to do something while a memory fetch is performed the CPU will just no-op.
