Intel's P4 3GHz w/ 800MHz Bus & Canterwood Chips

Posted by Hemos on from the faster-and-faster-it-goes dept.

OldGrayDave writes "Intel steps out today with their new Pentium 4 3GHz chip that runs on an 800MHz System Bus. They've also released "Canterwood", the chipset chipset for the P4 that supports Dual Channel DDR400 memory, native Serial ATA 150, RAID 0, AGP8X, USB2.0 and a host of other bells and whistles. Check out this showcase and performance analysis at HotHardware, to see what all the buzz is about. Intel distances themselves again from the Athlon." Or, you can read more at Hardavenue, mbreview, Tom's Hardware, hardware unlimited, or The Tech Report. I dunno...hardware gets faster, bus gets faster. Tide goes in, tide goes out.

  1. Re:What value are these new processors? by Anonymous Coward · · Score: 2, Informative
    I have two 2.8 GHz/333MHz P4s overclocked to 3.06 GHz/358 MHz.

    First one is for compressing DivX, doing distributed protein folding and for occasional game of Ghost Recon, Rainbow Six or Operation Flashpoint.

    On the second, headless machine I prototype my first principles calculations so that I can use all my supercomputer CPU time on actual production runs and not on debugging.

    I work as a microbiologist, and I occasionally do bioinformatics work. I can tell you that the real driving force behind most new biology is the microchip. I am very thankful that intel is putting that much money into R&D otherwise my data mining software might take 10 hours to run rather than 10 minutes.

  3. Now We Can Test Serial ATA by MBCook · · Score: 3, Informative
    Now we can test serial ATA to see how good it REALLY is. Before now it's always been an add-in, either a card or built onto the motherboard. Now that it's built into the chipset it's not at the mercy of the PCI bus, where it has to deal with your soundcard, your tv tuner, that firewire card you bought, and everything else. This will also bring about more SATA drives now that it's going to be on so many motherboards (I know many have them now, but this is an Intel chipset. This will push everyone to do it if they're not already).

    That said, I'm disapointed that you only get 2 SATA channels. Remember, with SATA it's only one device per channel, unlike parallel ATA.

      Not in this case. The block diagram clearly shows the SATA controller gets 150 MB/s bandwidth, 12% more than the PCI bus.

  4. 3 GHz Chip Delayed by lorax · · Score: 5, Informative

    News.com just updated their article on the chip to state that "a possible problem with the 3GHz Pentium 4, discovered at the last minute, forced the company to delay the chip late on Sunday."

  5. Terminator II Extreme Edition in HD by OG · · Score: 2, Informative

    The newest edition of the T2 DVD will include an HD transfer of the movie that can be run with WMP9. I tried to run a sample HD clip ("Step Into Liquid") on my computer (Athlon XP 1600 w/ 512 MB RAM)--I got a nice slide show of still frames. It ran a little better on my laptop. MS's website recommends 2.4 GHz minimum, and I can see why. T2 will be higher rez than that clip, so I'd expect you'd need something even faster.

    HDTV can also benefit, as new tuners like the Fusion HDTV card are inexpensive but have software-only decoding, putting a good strain on the CPU. I want one of these new chips. For the lust factor? Nope. There are applications I'm interested in that will actually benefit from the higher speed.

  6. Re:400MHz FSB on Athlons is trivial by gamorck · · Score: 4, Informative

    If you have a dual box I would recommend using "-j3" instead of "-j2". Typically "-j2" is the default for single CPU systems. Having make create one more thread than the number of processors you have allows you to make more efficient use of processor power. For example on my Dual Xeon with Hyperthreading turned on (looks like 4 cpus to linux and windows) I use "-j5" for maximum processor usage during the compilation process. When I turn off hyperthreading I typically use "-j3". I've found that these settings work very very well especially on Gentoo where you spend a lot of time compiling.

    Cheers,

    I wonder... How many chips could a chipset set if a chipset could set chips?

    The speed increments nowadays are much less steep than it was in the mid 90s.

    Not really. Granted, the speed increases were greater, but they came less often. The path from 100 to 200 Mhz Pentium took about as long as the path from 1.5 Ghz to 3.0 Ghz (which, by the way, has been out, sans the 800Mhz bus for a while).
