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 packageThe 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. Source: TechConnect Magazine, HARDSPELL
