The chip giant says they have already booted four operating systems (Windows Vista, Windows XP, Linux and Mac OS X) on the 45nm Penryn processors.
The company would not comment on whether or not Penryn's launch window was moved up, but added "These are good indicators of how healthy our 45 nm manufacturing and future product designs are looking so far as we plan to begin manufacturing production in the second half of the year ramping to three 300mm factories in 2008."
The two of the three 300mm facility mentioned are Fab 32 Chandler, Arizona and Fab 28 in Qiryat Gat, Israel. Development for 45nm processors is currently done at Intel's D1D facility in Oregon. All three facilities are expected to be fully production-ready for 300mm wafers on 45nm nodes by 2008.
