I'll be brief on this one. Intel Skulltrail is designed to compete against the AMD Quad FX platform. Although the Quad-Father was never popular enough, Skulltrail will share the same idea: dual Socket 771 Xeon processors like the 45nm Harpertown supporting up to 8 processing cores and fully-buffered DIMMs (FB-DIMM). The Skulltrail system will use the upcoming Intel D5400XS motherboard. With two NVIDIA nForce 100 MCP chips, the D5400XS will support up to four PCI Express x16 slots, finally allowing SLI on an Intel motherboard. The motherboard will have a 10-layer PCB with limited production (2000 units reported earlier) and price over US $600. Today's word is that the Intel D5400XS motherboard is scheduled for a launch on WW06. That's short for Work Week 6, tech-speak for the sixth week of 2008. In other words if that's true, expect Skulltrail to be launched somewhere around Febuary 4-9, 2008.
