IDF Spring 05 Intel will ship one further 90nm Xeon MP processor, codenamed 'Paxville', before moving the family to 65nm.

Paxville will, however, mark the Xeon MP line's shift to a dual-core design, set to take place during the first quarter of next year, Intel digital enterprise group VP Stephen Smith said today. It will ship in the same timeframe as 'Dempsey', the first dual-core Xeon DP chip, which we revealed last month.

Intel confirmed that Dempsey will be fabbed at 65nm, joining 'Presler' and 'Yonah, desktop and mobile processors made using the same process. The Xeon MP is a more complicated beast, so its transition to 65nm won't take place until Intel ships 'Tulsa', which it added to the roadmap last year. Tulsa's debut is expected in the latter half of 2006.

Tulsa will be followed in 2007 by the 65nm multi-core 'Whitefield', which will at last share a common interconnect and system logic chipset with 'Tukwila', the once eight-core now four-core Itanium, Smith said. The Register revealed Intel's plan to slim Tukwila's core-count last week.

Intel didn't disclose much about Dempsey or Paxville's design today, focusing instead on its upcoming desktop dual-core products and their successors.

However, it did discuss 'Mukilteo', its upcoming chipset for entry-level uni-processor servers based on the 'Smithfield' dual-core Pentium D and Pentium Extreme Edition chips. Mulkiteo will support DDR 2 SDRAM, Serial ATA with RAID and an 800MHz frontside bus, Intel said.

Those processors will also be pitched at uni-processor workstations, using the 955X chipset, formerly known as 'Glenwood'. ®
