cco stepping, cbo stepping, can you say confused?

[MoneyDontMatter]

I am planning on buying an Intel P!!! Coppermine. I'm not sure what clock yet, probably somewhere between 700-800 with an 100 Mhz clock. You can save all of your AMD praise because I am still a loyal Intel customer, although I am awfully tempted to but an AMD, but I still plan on buying an Intel. I've had nothing but horror story experiences with AMD and flawless performances with Intel. AMDs may be better processors but I haven't wuite seen enough evidence to make me stray from my intel cpu. But I'm close, my nest CPU will probably be an AMD, but not this one. I am not sure whether to overclock or not. Well, anyways, I was looking at the message board and I saw a few terms that I didn't know. What are cbo and cco stepping? What else is there? What is the difference? Which is the best?

I think the steppings are just the ways the CPU interprets instructions... Now, cB0 stepping is older than the cC0 stepping, and the reason that a new stepping is released is to mainly fix the bugs that associated with the older stepping.

Newer steppings are usually easier to overclock, due to more efficient running etc. The cB0 stepping 700e CPUs are, for instance, a lot easier to get up to 933 than the previous older steppings.

So try and get the cC0 stepping if you can.

Also bear in mind though the cC0 CPU now runs on 1.7V instead of cB0's 1.65V. Dunno why though... anybody with any ideas?

My last batch of cC0's yielded my best overclocking results ever. 1.7v vs. 1.65, is sometimes required to increase the yields. A 700 will more than likely get you the most speed.

Don't think so.

So it's just a revision of the chip?
But what KIND of revision then...? Like, technically it IS the same right?

I mean, I always thought it basically is just how internally the CPU routes instructions etc.

Any ideas?

Oh yeah, and computerwiz, why they need to increase the yield though?

Isn't the yield enough already? Does that mean that Intel's chip making process is like &quot;degrading&quot; ie. less CPUs are making the grade, meaning that they then increase the volts similar to what we do in overclocking?

 

[compuwiz1]

They can pull up some cpus that may have been binned at lower speeds, so in effect, they are doing as we do when we overclock.

The cC0 revision represents a major change in the CPU.

They hand laid-out some major paths and through re-routing, they decreased die size by about 10% without changing the process technology.

The cC0 stepping is definately a good thing to look for.
