DDR SDRAM & Athlon Specs

Posted by Hemos on from the power-to-the-masses! dept.

Mr. Wong writes "We've finally got some solid benchmarks of DDR SDRAM on an AMD Athlon. Rambus better watch out, DDR looks solid." As well, check out this submission: ph4t1dck writes "Anandtech managed to get a hold of an Athlon motherboard with support for DDR memory and then proceeded to put it through its paces. Looks like this could spell big trouble for Intel & Rambus since the Athlon with DDR seems to be destroying the P3 with RDRAM. It'll be interesting to see how the P4 fares in all this with its 400 mhz front side bus."

  1. Here's why .... by taniwha · · Score: 5
    Athlon has a 200MHz system bus (really 100 but they move data on both edges of the clock). On the other hand the PC100 memory systems only make ata at 1/2 this rate - this means that great bus is starved for performance and stuff must wait - even with PC133 it has to wait for the memory - to make matters worse K7 has cache lines that are twice as long - it has to wait twice as long as an Intel part - now with a 2x memory system and bus the latency for k7 is the same as that for a Pentium (latency is king for reads) and twice as much data is transfered to boot

    In other words K7's been crippled by its memory subsystem from day 1 -it's only now you will start to see it running at full speed ....

  2. Re:East Germany? by Anonymous Coward · · Score: 5
    But I thought East Germany no longer existed. Yet they are making RAM Chips?

    Yes, you are correct, they DID get rid of East Germany. Germany now has no Eastern region, as during the German re-unification a relativistic spatial contraction was performed upon the German landmass, thus compressing Germany into a two-dimensional region. Under EU law, this sort of national compression is legal, and is totally unobservable by the residents of Germany.

    Unfortunately, the huge area of Europe which was formerly occupied by the three-dimensional Germany is now a dangerous void. Anyone who falls into the aforementioned void will instantly be sucked into a parallel world of frightening paradoxes such as "What if I killed my own Grandfather?" and "If God made the world, then who made God?".

    People who happen to fall into this void are forced into an infinite lifetime of hard labour, where they are forced to make RAM chips from ear wax and their own anal hair. Once a week, a huge space cockroach called Tarquin descends into the void to harvest the RAM chips. The RAM chips are then distributed (by supernatural means) to shops around the world where customers may purchase them. This is how East Germany manufactures RAM.

    Thank you.
