Intel Tualatin Processors and Motherboard Support?

IntelIntrique asks: "I became intrigued when I learned about the new P3 Tualatin processors with a 512K cache, but was disappointed to learn that they require specific new motherboards to support the chips (Intel claims voltage changes). However, HotHardware features a review where they use one of these new processors in an Intel D815EEA2 motherboard, one that Intel shows as not supporting the new processor. What gives?"

"I have an D815EEA2, and I'd love to grab one of these new processors, but not if it means buying a new motherboard. Is Intel trying to prevent existing motherboard owners from cashing in on this new super chip? Are there any other slashdotters who have tried these new P3's in older motherboards with success? I'm mainly concerned with people using the processors in Intel boards, since it seems as though Intel would be in a unique position to know what types of new chips might be around the corner, and build unofficial support into early board revs."

    Intel has several different versions of the Tualatin, the 256K cache version for the desktop, and the 512K cache versions, one for the mobile segment and one for the lower-end workstation/server market. The Tualatin processors require a different stepping in the 810 and the 815 chipsets to support the new voltages as well as a new revision of 1.25V GTL versus 1.5V GTL+ used in the original Pentium III processors, which aren't compatible. More information about this can be found in the Pentium III-S Datashet here.

    As far as motherboard compatibility, I think Intel didn't want the 512K version of the Tualatin (aka the Pentium III-S) to flow through the retail/desktop channels because in a lot of cases, it performed better than their lower end Pentium 4 processor line. That's also the reason why Intel has slowed/stopped production of Pentium 4 processors below 1.6Ghz and will halt production of the desktop version of the Tualatin and shift the current desktop Tualatin into the Tualatin-based Celeron (but without data pre-fetch and only at 100Mhz FSB). More information can be found at the regular sites: Anandtech, Aces Hardware, Tom's Hardware.

      Sorry for posting as an AC, but I don't want any Intel lawyers knocking on my door for this...

      This post is right on the money - The reasons that Tualatin is not backwards compatible are for the voltage levels. There is also a differential clock compared to the Coppermine's single-ended clocking.

      One more thing - there are some pins that are used on the Tualatin that are not used on the Coppermine. I believe that these pins were originally designated as No-Connect (NC) in the Coppermine. However, some board manufacturers pull them up to VCC or down to ground. That means that the chip could end up getting cooked if you tried it in a non-Tualatin motherboard.

      Its really amusing to see how everybody can create such a conspiracy out of this. It's for engineering reasons, not some crazy marketing strategy that the Big Evil Company has cleverly crafted in a huge dark board room.

      In closing - buy Tualatins. They are really solid processors that offer good preformance.

The 0.18um version of the P4 easily hits speeds well above 2 ghz. (some over clocking number show 2.6Ghz). When the P4 goes to a 0.13um process it will be able to go even higher, as Intel has shown one at 3.5Ghz. The PIII at 0.13um will not be able to scale nearly that high, and thus won't be as fast.
