In the spirit of multi-core at IDF, Intel has officially named the dual core Smithfield based Pentium 4 processors - by ditching the number 4.

The desktop dual core processor is called the Pentium D, and here's its logo:

The 90nm Pentium D will debut at the following speeds:

Intel Dual Core Performance Desktop Lineup LGA775
Processor Speed L2 Cache FSB Launch
Pentium D 840 3.20GHz 2x1MB 800MHz Q2'05
Pentium D 830 3.00GHz 2x1MB 800MHz Q2'05
Pentium D 820 2.80GHz 2x1MB 800MHz Q2'05

Next up we have the Pentium Extreme Edition, also missing the number 4:

The Pentium Extreme Edition will only be launched at 3.2GHz and feature a 1066MHz FSB as well as Hyper Threading (2 threads per core, 4 threads total). The rest of the features remain identical to the Pentium D.

We can't help but think that the Pentium D logo looks a little too much like the Celeron D logo, but Intel has definitely made the Pentium Extreme Edition look somewhat more worth its price tag.

As we alluded to earlier, there is a bit of an issue with the way the Smithfield die is laid out in that it is a single piece of silicon consisting of two Prescott 1M cores. Although one of the cores can be cut away or disabled if it is useless, the problem is that we're now dealing with one very large core at 206 mm^2 and 230M transistors. Remember that chip defects increase by surface area, so manufacturing one very long piece of silicon lends itself to higher defects than two smaller pieces of silicon. Presler, the 65nm chip we talked about earlier today, gets around this by actually using two separate pieces of silicon for the two 65nm cores - Presler also uses the 65nm process to enable a full 2MB of cache per CPU, that's 4MB of total cache on a desktop processor.

More info as we get it...for those that are wondering, Gelsinger's keynote was infinitely better than Barrett's, in terms of interesting information.

    I agree it is a terrible name. It even looks like the Celeron D label. Why not just call the thing Pentium 5 and get it over with? Or is this just part of a new naming scheme for a platform (chipset/cpu/nic) liek Centrino? Reply

    I swear, Intel has an evil plot division specifically to come up with things like the Pentium D/Celeron D naming overlap to furstrate geeks. That or they're intentionally trying to confuse consumers in to getting the cheap Intel chip over the cheap AMD chip because it must have dual cores(it has a D!). Either way, this is a terrible name.

    damn you anand... "for those that are wondering, Gelsinger's keynote was infinitely better than Barrett's, in terms of interesting information."

    i cant wait!!

    Ohhhh let the confusion of Celeron and Dual Core lables begin!!! Reply

    D as in Dual core? or D as in the 4th letter of the alphabet? :D Reply

    The Celeron D and Pentium D will be confused in no time. Reply

    I think it's about time they changed the name. Average Joe was getting tired of the same old P4. Of course oblivious to the numerous enhancements made to the orignal debut core. Reply
