Its two fold imo.Does the quad core only work with certain software?
Yes. Applies to any multi-core processor. The software must be developed to run multi-threaded (parallel processing). Multi-core architecture is really useful in video rendering.Does the quad core only work with certain software?
Safari is multithreaded throughout.Its two fold imo.
First quad cores allows more active applications running at once with less of a perceived slow down. Then there's certain applications that will take advantage of the cores, like Photoshop, or Vmware.
If you're just using Safari, then email, or just one app at a given time, say Excel, then the performance difference will not be that much.
Is the 15-inch MBP using the same internals as the 27-inch iMac?
