John, What about Timna? I have heard two different stories about Timna. One is that it directly accesses SDRAM. The other is that it accesses SDRAM through a hub. I doubt that you will see any DRDRAM Timna systems. (Ten, can you verify this?) the ongoing debate about Rambus' inherent latency I have been trying to make the point that latency does not vary much from DRAM type to type. Bandwidth does vary quite a bit, but is of secondary importance to CPU performance (due to the very short bursts that CPUs typically perform.) It therefor makes no sense to pay a significant premium for DRAM bandwidth on a PC. Scumbria

John, Is there not some latency associated with moving data from the CPU chip to the chipset and then on to the memory, of whatever type. There is. Intel built the 386SL to address this, but it flopped. The Cyrix MediaGX (Geode) has an onboard memory controller, and is a huge success (now in the embedded market.) Timna is largely modelled after MediaGX, except that Intel may have made the mistake of putting a DRDRAM interface on it. This will add to system cost, and degrade performance through the translator hub. Scumbria
