Hot on the heels of the Core 2 Duo launch, Intel came out and released the world’s first quad-core processor last November. Given how powerful the Core 2 Duo had proven to be, we wondered how much of a performance gain this new quad-core version could offer.

According to our previous tests, there are currently no games that take advantage of the additional two cores; however software such as Photoshop, Pinnacle Studio Plus, QuickTime and 3D Studio Max all greatly benefited from the power of four dedicated cores. For example, the QX6700 was 15% faster than the Core 2 Duo E6700 in Photoshop, and gains as big as 43% were seen in Pinnacle Studio Plus. The biggest performance gap was found in 3D Studio Max where the QX6700 was 89% faster than the E6700.

Even though there will be those out there that will want the power of the QX6700 for image and video editing, the processor’s steep price ($1000) might set high barriers for getting one. Today Intel is releasing a second quad core processor called the Core 2 Quad Q6600. This new entry that comes clocked at 2.40GHz does not belong to the Extreme family of processors and will begin life at $530, making it a much more affordable alternative than the QX6700.
