Although HP's beastly xw8600 / xw6600 machines don't yet have a definitive ship date, it's looking like the duo will indeed be sporting a couple of Intel's forthcoming Penryn chips. Judging by the specifications list on HP's website, each workstation can be equipped with two of many Xeon 5200 (dual-core) or Xeon 5400 (quad-core) processors ranging from 1.86GHz to 3.33GHz. Additionally, the xw6600 features up to 32GB of DDR2 RAM, an internal DVD burner, a number of PCI / PCIe slots, seven USB 2.0 ports, FireWire, audio in / out, gigabit Ethernet, your choice of NVIDIA Quadro / ATI FireGL graphics cards and a 650-watt power supply to boot. As for the xw8600, it steps things up by supporting as much as 128GB of DDR2 RAM, making room for a few more 3.5- / 5.25-inch drives and PCI cards, and throwing in a more robust PSU. Not surprisingly, there are no pricing details available at the moment, but if we were bent over a barrel and forced to guess when we'd know more, we'd shoot for November 12th.
