Intel Quietly Introduces 3.8GHz P4

Posted by timothy on from the ouch-that-hertz-so-much dept.

BatonRogue writes "I didn't see this anywhere else, but it looks like Intel has quietly launched their Pentium 4 570J running at 3.8GHz. The J denotes Intel's Execute Disable Bit support, which they have also quietly introduced (it seems to save face of being 2nd to support it behind AMD). AnandTech seems to be the only place to have a review of the 570J. It performs reasonably well and even better than AMD in some areas, while falling behind in things like games. AnandTech has a nice one page benchmark comparison of the 570J to AMD's 4000+ as a quick reference."

  1. i recently built a 3.6 ghz intel by Indy1 · · Score: 5, Informative

    for a grad student at work (i work IT for the engineering college) and the grad student insisted on intel. I warned him that intels run hotter and louder (because they need more cooling) but he said intel anyways. Well once i delivered the machine to him, the first thing he said was "wow that thing is loud". I used a boxed intel cpu (which comes with the heatsink and fan) and when you put it under load, you can hear it clear across the room. Intel's heat problem is just ridiciously, and i am afraid to even hear what a 3.8 ghz would sound like when you ran it full steam.

  2. Massive power consumption difference by Brian+Stretch · · Score: 4, Informative

    Look at the power consumption difference between this new P4 and the Athlon 64. It's big enough between the 90nm P4's and 130nm A64's, but a 90nm P4 system uses nearly twice the juice of a 90nm A64. Mind you, that's the difference between entire systems, so the consumption difference between just the CPUs is even more extreme.

    Imagine a Beowulf cluster of these...

    Absolutely. Try processing 1920x1280 sized frames of video at 30 frames per second. Even if the bandwidth is there (and it is, just barely), the CPU doesn't keep up.

    Computer vision (and other computational perception/AI fields) eat up CPU like nobody's business... ... And while you may immediately think its research, it is entirely possible that people in the broadcast industry attempt to do this kind of thing on a daily basis ...
