Intel Moves To 533MHz FSB

Supporting processors come in speeds of 2.53, 2.4 and 2.26GHz. The 2.4GHz part is denoted as supporting the new FSB by a 'B' tagged to the end of it. And it appears as if the new chipset gives the P4 a performance boost in most apps over the previous 400MHz FSB chips and the Athlon XP." Meanwhile, back at the other processor ranch, firemoth writes: "Today OCAU has something special - They've gotten their hands on 3 AthlonXP CPU's based on AMD's new "Thoroughbred" core. This is the .13 micron process, of course, with lower voltage. This article compares them to the older Palomino core in both speed and temperature.. and they throw one into a Vapochill supercooling case and see just how fast it can go."

  1. i850E doesn't officially support PC1066 RDRAM by questionlp · · Score: 5, Interesting
    According to Anand's article on the new 533Mhz FSB P4's and the i850E chipset (which provides official support for the 533Mhz, aka quad-pumped 133Mhz, FSB), that Intel isn't officially supporting the use of PC1066 RDRAM modules which would allow the memory bus and the processor FSB to run in tandem.

    Although quite a few Samsung PC800 modules will run at PC1066 speeds without any problems, but if any installed modules are not capable of running at the higher speed, the memory bus will get capped at the current max of 400Mhz (or 3.2GB/s).

    I guess for now, the new processors don't really, really need the higher memory bandwidth, but as the processor speeds start to hit 3+ Ghz, the extra amount of bandwidth will become more important.

    Yeah, I don't know either. I work with 802.11b stuff a fair amount, but I'm no R/F engineer. Still, I can't help but imagine this becoming an all to common occurence:

    D: Greetings, Dell tech support.

    A: Hi, this new desktop you sold me is junk.

    D: What model is it?

    A: The new 2.4GHz P4, with the integrated wireless ethernet and wireless bluetooth keyboard.

    D: And what seems to be the problem?

    A: Every time I try to make a call on my 2.4GHz cordless phone, the computer crashes! And when I surf the web, my phone rings! And everything I type is ending up in my Palm's ToDo list! Then while I was upstairs heating my coffee in the microwave, it caught on fire!

    I mean really, how much stuff can we possibly cram into the 2.4GHz band anyway? Interesting times anyway.
