You have just purchased a new dual-core PC, but when you look at the Windows Task Manager’s Performance tab, you see usage statistics for four CPUs. What would be the most likely cause of this difference?
A) Dual-core CPUs appear as four separate CPUs in Windows
B) The dual-core CPUs are using HTT
C) The new computer uses dual-channel memory
D) Windows Task Manager is improperly configured
E) The computer is simply confused. Give it a moment to get its bearings.
The answer: B) The dual-core CPUs are using HTT
Hyper-Threading Technology is designed to allow a single CPU to schedule two processes at the same time, allowing the system to share the workload between both threads. If you view an HTT-enabled CPU in Task Manager, it will appear as if the computer has two or more CPUs for every physical CPU.

Want to know more? Watch “CPU Technologies.” CPUs are extremely complex components, and their inner-workings can contain a mix of memory caches, multiple processor cores, and advanced queuing mechanisms. In this video, you’ll learn how these technologies work together to create today’s modern central processing units. |
