Intel Xeon to get a new stepping

Intel's dual and quad-core Xeon 5100 "Woodcrest" and 5300 "Clovertown" processors will get a stepping change to G0. This new stepping features better energy efficiency and virtualization enhancements.

DailyTech writes:

Stepping G0 reduces power consumption during C1E halt states. Intel does not state how much less power stepping G0 processors consume in idle states except “some amount.” Intel improves VT technology in stepping G0.

The enhancements include:
  • APIC Task Priority Register (TPR) Virtualization
  • NMI-window exiting
  • Advanced VM-exit information for INS & OUTS
  • All stepping G0 processors will receive new CPUIDs. The Clovertown CPUID will change from 06F7 to 06FB while Woodcrest changes from 06F6 to 06FB. Stepping G0 processors will also receive new SSPEC numbers.

    The new G0 stepping only requires a BIOS update to work properly.
