According to industry sources, Intel Quad core 45nm will show up its face only in March. Even then Intel will be able to ship it in limited quantities and of course, we are talking about the desktop chips. Intel is currently shipping a limited quantities of Xeon based 45nm quad cores and a high end 9650 3.0GHz quad core part.
The current plan is to fill the gap with 65nanometre chips and survive until the 45nm Yorkfield mainstream quad cores comes in game. Intel plans a limited availability of 45nm Yorkfields in March, but this will be enough to claim to investors that they started shipping them in Q1.
With AMD who doesn’t really have the parts to compete makes Intel comfortable and gives a giant some time to rest.
