Sources inside Intel claim that the outfit is set to release its new Xeon server chips next month. The leakage is nothing to do with the fact that AMD announced its new server chip yesterday and is no way seen as any form of PR spoiler, as if Intel would ever do that.

The new chips will be based on the Nehalem microarchitecture, which Intel claims cuts down on bottlenecks. Nehalem chips are also able to execute more tasks while drawing less power. The company will deliver new Xeon server processors belonging to the 5500 and 3500 chip families starting early August.

Just in case you were wondering the secret source said that Intel will launch quad-core desktop chips code-named Lynnfield in early September, followed by quad-core laptop chips code-named Clarksfield later in the month. Officially Intel is saying nothing other than Lynnfield and Clarksfield are on track for second half 2009 production.

Lynnfield and Clarksfield chips use the 45-nanometer process and will be shipped before before its move to the more efficient 32-nm manufacturing process later this year. We are expecting to see chips for new ultrathin laptops too. The Celeron SU2300 and Celeron 743 processors will be out in September.

So far Nehalem-based chips have been reserved for expensive systems like servers and gaming PCs.
