Intel has revealed its latest Montvale-based processor line. The new Montvale-based processors (which will replace the current Montecito-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 such as a faster 667 MHz front-side bus and the demand Based Switching with Enhanced Intel Speedstep Technology that allows the higher-end Itanium 2 9100-series models to enter a low-power state when idle.
