Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core 2 Quad Q9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
