Just when we were getting excited about the Core 2 Duo chips that have become standard in everything from the 24-inch iMac to new Dell laptops, we"ve now got quad-core fever. Yes, Intel already has the shown them off before, but Tom"s Hardware has a very thorough investigation into the nature of these four-headed beasts -- what Tom"s is dubbing the Core 2 Quadro. (Of course if this really is the name, Intel may have to chat with NVIDIA first, as it already uses the name Quadro in a set of graphics cards.) So how"d it turn out? Not surprisingly, video editing and rendering are everyday tasks that took advantage of all four cores.
