R0 vs M0 stepping

[cybergunkoo81]

Hi,

I heard that Intel E5200 2.5ghz that has R0 (SLB9T) stepping is better in oc than the M0 (SLAY7) stepping, is it true?what's the difference between those two?

Here are the specs. It looks like R0 is a later release.
Can't find any difference other than that.

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.
