List of future Intel Xeon microprocessors

From Wikipedia, the free encyclopedia

This article contains information about scheduled or expected future computer chips. It may contain preliminary or speculative information, and may not reflect the final specification of the product.

The Xeon microprocessors from Intel are CPUs targeted at the server and workstation markets.

It is not yet clear whether there will be a native Merom-based server processor with four cores on a single die sharing a large third-level cache; at earliest this would appear in the 2008 timeframe. It's very likely we won't see a native quad-core based on Core microarchitecture, with the advent of the first native quad-cores by Intel to come with the arrival of Nehalem and its derivatives in H2 2008.

In October 2007, PC Watch claimed ^[2] the existence of Dunnington, a 45nm processor with six Intel Core microarchitecture cores made up of three dual-core Penryn dies. sharing a 16MB L3 cache. This would be a replacement for both Tulsa and Tigerton, designed for four-socket configurations using a 1066MT/s front-side bus. This processor will be sold prior to the release of the Nehalem architecture, in Q4 2008.

An article from DailyTech^[3] states that each pair of Penryn cores will share 3MB of L2 cache and will launch in the second half of 2008.
