Q: If I have a dual CPU that runs at 3.0GHz and a Quad that runs at 2.7GHz?

Which would be faster?

Whats the difference?

    Dual and Quad refers to the number of ‘cores’ or independent processors on the CPU.

    Generally having more cores is better for multitasking, as most applications can only work on one core at a time. However, with dual and quad core more and more software, like games for example, is being written to support multiple cores.

    Which is faster? Ghz isn’t an accurate way to compare processors, in-fact there isn’t anything you can read on the box that will help to really compare chips. You need to look at independent benchmarks to get a good picture.

    Whenever I need to compare CPUs I always look them up on http://www.cpubenchmark.net/ they have benchmarks for just about every processor out there.

    So look up the specific CPUs that you are interested in there to see how they stack up against one another.

    If the benchmark numbers and the price are basically the same, get the dual if you’re primarily a PC gamer, get the quad if you’re not.
