Intel launches Tulsa server chip

The introduction of Intel's Core 2 Duo and Xeon 5100 processors may have rendered Netburst obsolete, but the architecture isn't ready to go down just yet. Like a cartoon villain throwing on his giant robot suit as a last resort to defeat the protagonists, Netburst has strapped on a whole lot of extra cache and re-materialized in the form of new Xeon 7100-series "Tulsa" chips. The new processors clock up to 3.4GHz, pack up to 16MB of cache, and from what Intel told us, draw up to 150W of power. The complete "Tulsa" lineup launching today is as follows:

Speed Cache FSB Price
Xeon 7140M 3.40GHz 16MB 800MHz $1980
Xeon 7140N 3.33GHz 16MB 667MHz
Xeon 7130M 3.20GHz 8MB 800MHz $1391
Xeon 7130N 3.16GHz 8MB 667MHz
Xeon 7120M 3.00GHz 4MB 800MHz $1177
Xeon 7120N 3.00GHz 4MB 667MHz
Xeon 7110M 2.60GHz 4MB 800MHz $856
Xeon 7110N 2.50GHz 4MB 667MHz
Intel says the family also includes lower-power 95W options. Considering Intel's pricing scheme, low-power models are likely those with an "N" suffix. The Xeon spec sheet has yet to be updated with the new processors, though, so we can't say for sure.

Electrical power aside, Intel says the new chips bring huge processing power gains over their single-core predecessors—up to twice the performance and three times the performance per watt, to be exact. Of course, the company avoids direct comparison with the new Xeon 5100 chips, so right now it's anyone's guess how much all that cache really helps Netburst. Nevertheless, Intel expects 40 system manufacturers worldwide to release servers based on the new chips. Dell, for one, is already offering the new processors in its four-way PowerEdge 6800 server.
