Dan, that's incorrect. When DDR comes out for PCs, it will run either at 200 MHz or 266 MHz. (Actually, the main clock runs at 100 or 133 MHz, but the data is double-pumped.) This means the max bandwidth is either 1.6 GB/sec or 2.1 GB/sec. RDRAM at 800 MHz has a max bandwidth of 1.6 GB/sec, but it more efficient at using that bandwidth, meaning that DDR at 200 MHz isn't going to cut it.

You're probably thinking about DDR-II, which will run at 400 MHz (2x200 MHz). That won't arrive in the market for quite some time.
