Intel Moves To 533MHz FSB

homerj79 writes: "Intel has launched an upgrade 850 chipset and faster Pentium 4's today. The new chipset, dubbed the 850E, supports a 533MHz (133MHz x 4) front side bus, as do the processors. 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.

  2. 2.4GHz clock speed by dattaway · · Score: 4, Funny

    I remember the old ZX81 I built from a kit clocked its Z80 at 3.58MHz, so it could generate the synced television picture directly from the processor.

    With 2.4GHz, I'm sure there will be wireless experiments by attempting to use the CPU as a DSP.

    when the clock speed of the latest chipsets is faster than the clock speed of your processor, motherboard, and memory. Combined.
