Intel is going to launch their 6 core processors codenamed Gulftown very shortly. They have differentiated their high-end from their mainstream by having completely different chipsets to support them. The X58 chipset was launched last year along with the LGA-1366 Core i7 CPUs. Intel launched their P55 chipset later this year along with the LGA-1156 Core i7 CPUs and Core i5 CPUs.
Intel designed the X58 chipset for the high-end with things like multiple PCI Express lanes for graphics and triple channel memory support built into the X58 chipset which the P55 and H55/H57 do not support. In preparation for the launch of the new CPU, motherboard manufacturers are launching new versions of their favorite X58 motherboards to support the new CPUs (older X58 boards should work with a BIOS Flash) and newer technologies like USB 3.0 and SATA 6Gb/second which are the new standards interfaces. Today, ASUS, one of the better motherboard manufacturers is launching their P6X58D Premium board and that is the board on the test platform. As the Gulftown CPUs are not released this review will use the Core i7 920 CPU.
