DailyTech has some info about a new update to Intel's Itanium 2 processors:
Intel is preparing to launch the next iteration of its dual-core Itanium 2 processors, Montvale. The next-generation Montvale-based Itanium 2 replaces the current Montecito-based Itanium 2 9000-series. Intel positions the Montvale-based Itanium 2 processors towards mission critical tasks, with scalability from two to 512 processor sockets – for up to 1024 processor cores.
The new Montvale-based processors retain the Itanium 2 name, but with a different processor number. Montvale-based processors will carry the 9100-series processor number to differentiate from the Montecito-based 9000-series. The new Itanium 2 9100-series has minor upgrades over the 9000-series.
New to the Itanium 2 9100-series is Demand Based Switching, or DBS, with Enhanced Intel Speedstep Technology. DBS allows the higher-end Itanium 2 9100-series models to enter a low-power state during idle periods. The feature is only present on the Itanium 2 9140N, 9140M, 9150N and 9150M. Despite DBS being present on the higher-end Itanium 2 9100 models, all dual-core 9100-series processors have 104-watt TDPs.
