P4 XP reporting two cores??

post #1 of 4
Thread Starter 
For the holiday we're visiting my mom and I'm noticing that her P4 2.8GHz machine is reporting two cores in Task Manager. I installed the folding SMP on her machine and it installs and responds as though there are two cores. Yet the specs I can find all point to a single core. Did I miss something?

^ That. Basically what it does is to allow one physical core as act two logical cores. It allows wasted clock cycles (common on NetBurst CPUs thanks to their deep pipeline) to be used by the other threads; it makes the CPU multitask a whole heap better. It's perfectly normal.

Ok, thanks. I did the google, but without that Hyperthread business, it's bleaker.
