chrisj1968 Posted December 1, 2014 Share Posted December 1, 2014 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 Link to comment Share on other sites More sharing options...
Hum Posted December 1, 2014 Share Posted December 1, 2014 2 cores - 2 physical CPU cores4 logical processors - 1 additional "logical"/"virtual" processor per coreThat 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. https://answers.yahoo.com/question/index?qid=20100722001023AAeXXH6 http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/changing-the-number-of-logical-processors/179f1a31-7766-472e-9383-7c3dcc3281a6 Link to comment Share on other sites More sharing options...
Max Norris Posted December 1, 2014 Share Posted December 1, 2014 If I recall, it's a Hyperthreading trick. Two virtual (logical) cores per physical core. (Edit: Faster typer above.) Link to comment Share on other sites More sharing options...
vcfan Posted December 1, 2014 Share Posted December 1, 2014 logical processor = cpu thread Link to comment Share on other sites More sharing options...
chrisj1968 Posted December 1, 2014 Author Share Posted December 1, 2014 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. Link to comment Share on other sites More sharing options...

AMD's do a similar trick (Bulldozer), have a few processors here that do that, two virtual cores per each physical. Link to comment Share on other sites More sharing options...
chrisj1968 Posted December 1, 2014 Author Share Posted December 1, 2014 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 Link to comment Share on other sites More sharing options...
