Intel Core 2 Duo E8400/E8500 and Xeon E3110 Moving to E-0 Stepping Next Month
After moving all 45nm Xeon DP quad core processors from the C-O to the E-0 stepping, Intel announced today that three more 45nm processors will also be upgraded to E-0. The two desktop Core 2 Duo E8400 and E8500 plus the server Xeon E3110 CPUs will all be updated to the E-0 stepping next month. Changes that will come with the E-0 stepping include:

• - CPUID will change from 0x10676 to 0x1067A
  - Power Status Indicator (PSI) is supported
  - PECI implementation change
  - New instructions added - XSAVE/XRSTOR
  - New ISA extension for save/restoring context of x87, SSE, and future processor state
  - New feature added - ACNT2
  - Improved mechanism for determining processor utilization. To be used for more efficient P-state determination.
  - Package change to Halide free package

The E-0 processors will not require any BIOS updates. They'll be easily recognisable by the new sSpec numbers: SLB9J for E8400, SLB9K for E8500 and SLB9C for E3110.
