Tualatin confusion?

[batboy]

I've been mildly interested in the new "P-III" which has a .13 micron die and new core with mostly P-III style technology. Intel mainlly designed this as a mobile CPU, or in other words, it's the new laptop processor until the P-4 mobile chip is introduced next year. The die shrinkage and lower core voltage will help it run cooler and on less power, which is good for laptops and overclockers alike.

A couple of confusing points that seem to be causing people problems. First, the P-III cD0 stepping just introduced is a coppermine stepping. Sounds like a few folks thought this was the new Tualatin CPU, nope. The second thing that still confuses me is whether the new Tualatin 133 FSB 1 gig and 1.13 gig chips will work in existing motherboards. What I'm reading is that it needs a different chipset. But, Intel is merely slightly modifying the 815 chipset and releasing another "stepping" to allow the Tualatin to work.

The real issue is since this is a potential overclocking hotrod with the new .13 micron die, how will it work in our desktop O/C systems. If Intel was smart, they would have an easy fix for any compatibility issues in order to extend the upgrade path of our current machines. It would fill a niche until we finally decided to plunge into the P-4 market. AMD does not have a good mobile chip right now and is frantically trying to get something to market. Don't screw up Intel. Give us older P-III an upgrade path and having the top end mobile CPU would have to help sales a lot and give AMD a black eye. Bets are all off if we have to buy new motherboards.

well, i was missinformed about the cD0 stepping...i thought the cD0 was in lieu of the tualatin chip....sorry to all i have told otherwise......now my question is what chips have the cD0 stepping? I use to have a chart from Intel but never saw the cD0 listed on it, and of course I cant find it....

The first little "c" in cD0 means coppermine. This is just another "stepping" or minor improvement in the Celeron II and P-III coppermine core. The speeds I don't remember for sure, but probably about 800 MHz to 1 gig chips. Chances are that the new cD0 chips will be a nice overclockers. However, the cD0 stepping has nothing to do with the new Tualatin chips.

Anyone know if the Tualatin can be "adapted" to current P-III motherboards? I think the core voltage is 1.3, which might be a problem on some motherboards, but my Abit SA6R already goes down to 1.3v in the BIOS. Running a little higher voltage might help overclocking stability, if that is the only issue. I think SIS already released a Tualatin compatible motherboard just recently.

Ok, so the slightly modified 815 step "B" chipset will support the new Tualatin. What all was changed? What is the step "B"? Will a Tualatin work on my Abit SA6R that already has a setting for 1.3v? Why is there snow? What is the meaning of life?

Core voltage is it, stepping remains the same... right?..

It should, see first response...

Why is there snow?

Most precipitation starts as ice crystals that melt as they fall into warmer air. Snow is the ice crystals never melting (and combining into large flakes).

What is the meaning of life?

see this site (http://user.mc.net/~manos424/python/mol1.txt) for the meaning of life.

Ed posted an article on the home page of this site about the Tualatin. Sorry guys, sounds like the pin arrangement is different too. He's saying you need a Tualatin supported motherboard. I was afraid of that, but wanted to be hopeful. There could be an adaptor eventually made, but it's unlikely to be a cheap $15 slotket like we saw before. Pinky, thanks for the meaning of life!

Regarding the use of the new .13 micron chips from Intel, it appears to me that the current motherboards may not support the new cDO 13 micron chips and why i'm saying this is that i've noticed that Gigabyte have just released the GA-6OXET motherboard using the 815EP chipset,which they say has a Universal socket to support both the current PIII's and the new PIII's that are due for release in the near future ....i assume in the near future shall i say. They call it the "Blue Thunder Universal Socket"
So, if that's anything to go by i think we may have to replace our mobo's if we are going to go to the new PIII's....my two cents worth anyway.

MAV, I think you're right about the Tualatin looking like it needs a different motherboard chipset, but you mentioned cD0 stepping of the 0.13 micron chip and that part is not correct. The new Tualatin core will most likely be a tA0 stepping. The cD0 stepping is a continuation of the coppermine core like the P-III 1 gig chip, etc.
