Number of Windows displayed in CPU Usage records in Task Manager

The windows in the Performance tab CPU Usage records in the window task management were puzzled. Why some computers show 1 windows, some computer shows two, and the server has some display window even 16, 24 more that.

I have been told that there are 1 representatives of the CPU is a single core, and two represents the CPU is dual-core. That server has 16, whether it represents the server is 16 core that.

Server One (2 Intel Xeon E5620 CPU Display)

Server Two (2 Intel Xeon e5-2620 CPU Display)

There are questions, on Baidu search the next CPU some of the general parameters, knowledge. The records are as follows:

1, the CPU can have a single core, dual-core, 6-core, 8-or even 16-core, etc., but not necessarily the number of cores, the better performance. Baidu Encyclopedia said: 16 core CPU does not have 8 core CPU operation speed, because the core too much, but not reasonable allocation, so that the operation slowed down.

2, the early single core CPU using Hyper-Threading technology, simulation of 2 CPU cores, in the use of records here there will be 2 windows to display two logical kernel of the work record. In this way, although there are only 1 single core CPUs, there are two windows that can be seen in the use of records.

3, while the CPU use the number of windows in the record, can be understood as a thread to use records. The number of Windows here corresponds to the total number of threads for all CPUs in the entire system.

I went online to see the next Intel Xeon E5620 parameter is 4 core 8 threads. And the server has 2 of the CPU, it is 8 cores, 16 threads, so the window that block shows 16 windows.

The Intel Xeon e5-2620 parameter is 6 cores 12 threads, the server two also has 2 this CPU, then is 12 cores, 24 threads, corresponds to display 24 windows.
