Intel 'Tulsa' 65nm Xeon MPs to ship 27 August?

Conroe-based Xeon 3000s coming a month later

Intel appears set to introduce a new line of dual-core Xeon MP server chips on 27 August, bringing the family into the 65nm era and once again equipping its top-of-the-line x86 server chips with L3 cache.

The new line-up is currently best known by its codename, 'Tulsa', but it will ship as the Xeon MP 7100 series. Unlike, the 'Woodcrest' Xeon DP 5100 line, Tulsa is based on Intel's previous-generation architecture, if past pronouncements from Intel executives are anything to go by. We'll have to wait for 'Tigerton' and 'Dunnington' for next-generation architecture Xeon MPs.

According to leaked roadmap slides posted by Chinese-language site HKEPC, the 7100s will ship in two forms, with 'M' and 'N' suffixes, respectively. The former run on an 800MHz frontside bus, the latter on a 667MHz FSB.

With any given model number, there will be both M and N variants, with identical pricing. So, for example, there are two 7140s: the 7140M, clocked at 3.4GHz, and the 7140N, clocked at 3.33GHz. Both are priced at $3,157, the slides reveal. There are M and N versions of the 7130, 7120 and 7110, priced at $1,980, $1,177 and $856, respectively.

The 7100 series will be followed in September by the anticipated Xeon 3000 family, a line of chips for single-CPU machines. The 3040, 3050, 3060 and 3070 - clocked at 1.86, 2.13, 2.4 and 2.67GHz, respectively - are based on 'Conroe', the desktop Core 2 Duo part Intel announced last week. They all have 4MB of L2 cache and run on top of a 1066MHz FSB.

The 3000 series - which form the basis for Intel's 'Kaylo' platform - had been expected to ship in August. They will be backed by the 3000 family of chipsets - aka 'Mukilteo'. The 3040, 3050, 3060 and 3070 CPUs will be priced at $188, $224, $316 and $530, respectively. ®
