Intel's Pentium Dual-Core E5200 processor is getting on course for a specifications update. The chip will feature in a new, improved Wolfdale-2M core, spec'd out as the R0 stepping, from its current M0 stepping. The new stepping is intended to add new instructions, power-management features, and bring about changes in the chip-package. A short list of known changes is as follows:
- CPUID changed from 10677 to 1067A
- Power State Indicator (PSI) support with Intel 4 series chipsets
- New instructions - XSAVE and XRSTOR
- New S-spec and MM numbers
- New halide-free chip package
Due to the changed CPUID, users may require BIOS updates to detect the CPU. According to the company, E5200 R0 should be out by April 13.

it was pretty expected from intel cause they get short of working old M0 dies :laugh: and newer e5300 and e5400 are based on R0 from their start (jan2009)
I just wish they wouldn't disable the extra instruction SEE instruction sets on these processor. Virtualization and execution disable bit I can understand.

I know, I was making a more broad statement about Intel disabling them on their processors processors, not specifically the E5000 series. I can understand why they would disable Virtualization and the NX-Bit on processors, but not the extra instruction sets. Sorry, I should have been more clear.

I love my E5200, it does EVERYTHING running at 3.8 GHz easily, and thats with C0 stepping.
