Benchmarked: The Quad-Core i7 iMac is Super Fast

Our iMac review included a 3.06GHz Core 2 Duo chip inside, but we received the top-of-the-line iMac housing the more promising 2.8GHz Core i7 processor. Do more cores make up for lower clock speeds? Yes. Often 2X to 3X. » 11/18/09 2:00pm 11/18/09 2:00pm
