The chip giant has already launched Westmere for the desktop and mobile environments at the start of the year, and it will transition the technology to server-oriented Xeon chips within three months.
To retail as the Xeon 5600-series, the new chips will be available in four- and six-core models for use in dual-processor boards. Intel will also finally release the eight-core 'Beckton' Nehalem-EX chip that's based on older 45nm Nehalem technology.
The new Westmere Xeons will be a drop-in upgrade to existing 5500-series chips. Generalising somewhat, the 32nm production should increase performance over incumbent Nehalem by adding in more on-chip cache and leveraging the chips' enhanced instruction set.
What remains to be seen is how Intel uses Westmere's integrated graphics, if at all, in a server environment, and we'll learn more before the official launch in March.
