The Pentium 4 needs memory bandwidth, and DDR doesn't supply it. Or does it? Anandtech, ironically, has a preview of the E7500 chipset from Intel - dual channel DDR with support for up to 16 gig of RAM. With a new bus architecture, this looks perfect for high-load databases that need wide pipes to hard-drives, memory, and ethernet. Both of these technologies look great for mid-range database servers. Anandtech claims that dual DDR200 will provide 3.2 gig/second bandwidth, where Tom claims that DDR266 (single channel) offers only 2.1 gig/second. Intel is sure hedging their bets. I wonder what AMD has up their sleeves."
