Second-class Intel to trail AMD for years

Well, if I'm not wrong, AMD will be aiming at DDR2 800 with socket M2, so there's no reason of concern here.

The hard sources that I've read seem to indicate that the M2 will only support DDR2 667 at launch. However, both the socket and the memory controller are designed to expand to DDR2 800 which will probably be added through a core revision later on. Since the M2s are launching before Conroe, AMD is probably saving DDR2 800 until after Conroe is released to give the K8 added punch as a response.

"Memory timings are the performance-determining factor with Athlon 64 systems, but they are not with Pentium 4 platforms. All of our tests indicate that systems with high-frequency memory deliver the maximum performance. This is especially conspicuous when the FSB is clocked at 1067MHz: the systems with DDR2-1067 and DDR2-800 SDRAM are always faster than the systems with DDR2-667 and DDR2-533 SDRAM irrespective of the selected timings."

What a truly stupid conclusion. They change the frequency by 25%, and equal the latency change performance, and say frequency is more important.
How much did they effect the total latency?
I think the total system latency for prescott is ~ 100. That means a 15% decrease in latency is = to a 25% increase in frequency, and yet they conclude that frequency is more important.
The real suggestion here is that a change to an ODMC would be equivalent to a 75+% increase in fsb speed.
