CPU stepping revision

[ebalong]

Okay, here is a question that many will probably think non-worthy or trivial, but - how many stepping revisions has, say the 2500K gone through? Mine that I purchased in November reads as "D2" in CPUID, so does that mean that someone that purchased their chip in, April of last year has a different stepping? I occasionally hear vague references to CPU steppings, but when I google it, I can't find a definitive resource listing the past and present steppings of a given processor. It seems like stepping revisions are semi-important because they may correct bugs or other things, but they are never announced, yet some seem to know about them through some weird insider info.

Usually CPU stepping revisions are due to minor voltage adjustements http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-%288M-Cache-up-to-3_80-GHz%29

Ah, yes, I see that some processors only have one stepping throughout their lifetime. The 2500K has always been "D2", I believe, while the 3930K for instance has both C1 and C2 revisions. It seems mobile chips have a greater number of revisions.
