  • The 133 MHz FSB

    The Front Side Bus is the bus connecting the CPU to the MCH. In older systems this bus was the system bus. The FSB is dependant on the CPU; the older Pentium IIIs ran on a 100 MHz FSB. But the i820 chip set was intended to be used with the newer Pentium III "Coppermine", which operates at a multiply of 133 MHz.

    The increase from a 100 to a 133 MHz FSB is not as important as it sounds. This is due to the fact that the greatest work is performed inside the CPU and between its L1 and L2 cache, where a powerfull bandwidth really is essential.

    The data intensity between CPU and RAM is less demanding. However a 133 MHz FSB will give better performance when working with lagre data amounts (using Photoshop for instance).


    A conclusion

    We have not tested a 820-based board ourselves. However, we did like the 810-based board we used for a while earlier. Not for gaming - but office use, it was and it is a fine little chip set.

    The i820 thing has been a disaster for Intel. First it was discovered, that you only could use 2 out of 3 RIMM-sockets. Then the MTH did not work. Today some analysts believe, that Intel will stop producing chip sets after all this chaos. I understand them, but it will be a pity. Intel used to produce excellent chip sets, and they should continue.

    The i820 chip set should have been brought out of circulation a long time ago. The new i815 chip set could probably take over, so the venerable BX set could retire.

    We see two points in which Intel has failed, and this could easily have been avoided:

    First of all the company should not commit themselves to an uncertain technology like RAMBUS as they did. Intel produces great CPUs. The customers might use them with Rambus or SDRAM or DDRRAM or EXP3RAM or whatever the industry might come up with.

    We believe that Intel trusted to much in own powers; they wanted to "force" the market into a certain behavior. We do not like that; it is against the free will and intelligence of users all over the world. Last time Intel tried this attitude was in 1997 when skipping Socket 7 in favour of Slot 1. A clupmsy design, which they now have abandoned themselves.

    The second lesson is that Intel never again should market untested products. We have seen this several times during the "Caminogate" affair. Maybe Intel has felt threathend by AMD's succesfull Athlon project. But there is no excuse for marketing lousy untested products. Both Intel and Microsoft should learn from this.
