[QUOTE="Exodist, post: 1548880, member: 284358"] This is a old thread, hope no one shoots us for necro-ing it to much.. LOL But I will answer your question. This is a un technical way of looking at it. If you have 2 cores at 2Ghz. You basically have 4Ghz of computing power.. If you have 4 cores, then you have 8Ghz worth of computing power. Well thats the idea but it doesn't always work out that wonderfully. But lets say you have dual core 3Ghz CPU and another quad core 2Ghz CPU. If the software is not wrote for multithreading then the 3Ghz dual core Cpu will out perform the quad core CPU. But that software will also only be using one of the two cores on the dual core CPU. However most software is now wrote for multithreading and should utilize the power of the 4 cores in a quad core CPU. This is a cheesy way of looking at it, but thats basically the sum of it. Now intels current i5 line are both dual core and quad core CPUs that are multithreaded. This is not to get confused with intels i7 line that has HYPER threading. Hyperthreading shows up as 8 cores, although it really is only 4 physical cores on the chip. Read up on it here.. To much to type..
