New Pentium Chipsets Launched

Posted by Zonk on from the we-have-the-technology dept.

MojoDog writes "Today Intel has officially taken the wraps off their new mainstream Pentium D 820 Processor and i945 Express series chipsets. Additionally, they also cranked up the Pentium 4 6XX sequence line-up to include the new Pentium 4 670 at 3.8GHz. The Pentium D 820 is Intel's new dual core CPU clocked at 2.8GHz, which contains two Prescott cores per die but doesn't support HyperThreading like the Pentium Extreme Edition 840. The i945 is their new mainstream PCI Express based chipset, one version of which has Integrated Graphics and both supporting these new dual core CPUs. Additionally, Intel took their Pentium 4 6XX sequence processor, based on the Prescott 2M core, for a speed bump to 3.8Ghz."

  1. No hzperthreading shame that by FidelCatsro · · Score: 2, Insightful

    Well considering that security alert recently about the problenms with hyperthreading , and given the fact that the chip is duel core anyway which greatly reduces the need for hyperthreading i don't really see it as too much of a loss and quite possibly its an advantage.

      The security problem can be easily fixed in a new core revision. The main problem with Intel's hyperthreading is their somewhat simplistic implementation, which greatly limits performance (for instance, when you enable HT, most of your out-of-order structures are physically halved).

      From a technical perspective, there's still a great deal of value from doing (proper) HT on top of a 2-core design - namely, you get 4 execution contexts. But that negatively impacts sales (very few would still need SMP, for instance)

  2. naming convention by y2dt · · Score: 5, Insightful

    a Pentium 4 670 at 3.8GHz, Pentium D 820 at 2.8Ghz, a Pentium Extreme Edition 840 w/o HT, and a Pentium 4 6XX based on the Prescott 2M core???

    seriously, how is this naming convention better than the old one?

    Unfortunately, the actual data in that article produces a different conclusion. Anand just draws the wrong conclusions. As usual.

    The 2.0ghz Pentium M performs within 10% of a Pentium 4 3.6ghz in most tests. That isn't exactly not competing.

    Anand then saws that it can't compete because of price and lack of chipsets. Well, no shit. They produce mostly Pentium 4 chips for the desktop, not Pentium Ms. Ever heard of economies of scale? And you can bet that if Intel decides to switch to a Pentium M-based design for its next desktop chip, they will have a much more modern chipset to go with it.
