Problem
My processor is an Intel Core i3-380m. As you can see, it's 2 cores and 4 threads. Although, both Ubuntu 11.04 and Windows 7 seem to think it's a quad-core CPU: Why is this? Is it because there are 2 threads per core, dividing the CPU in 4 processing units?

Fix for: Why is my dual-core CPU recognized as a quad-core one?
Low Risk
The reason is hyperthreading, which your processor supports. Hyperthreading isnt the equivalent of an extra processor, but can really boost performance on multithreaded applications. For each processor core that is physically present, the operating system addresses two virtual processors, and shares the workload between them when possible.
