Can someone decipher this info?


Recommended Posts

I used to own all AMD systems but crossed over to an Intel Core i7 Laptop. When I go into the taskmanager, I can't switch the CPU usage to cores just logical processors. What in the world is a logical processor? and why doesn't Intel processors allow for viewing usage of each core? I haven't owned an intel system since circa 1998. below is the screen shot of my taskmanager

2 cores - 2 physical CPU cores
4 logical processors - 1 additional "logical"/"virtual" processor per core

That is, the computer addresses each core like it is 2 cores and shares the workload between the 4 as efficiently as it knows how. It's also known as Hyper-Threading/HT.

If I recall, it's a Hyperthreading trick.   Two virtual (logical) cores per physical core.   (Edit: Faster typer above.)

So intel are actualy better CPU's. based upon what I have, I have 4 cores= 2 logical processors x 4 cores = 8 logical processors... ok Got it.

AMD's do a similar trick (Bulldozer), have a few processors here that do that, two virtual cores per each physical.

interesting technology to say the least. I used to keep up with the know on processors. But at my age, I've been out of that for sometime
