[plug] ddr really faster then sdram for linux kernel ?

Hi - I wondered if this article might hold some answers:

Back in August we took our first look at all but one of the DDR chipsets 
for the AMD Athlon processor and found a pretty interesting battle over the 
speed crown between AMD's 761 chipset and VIA's KT266 chipset. A lot has 
happened since then with the release of VIA's KT266A chipset and 
motherboards finally being shipped with the new NVIDIA nForce chip. With 
these new chipsets a new level of performance has been reached for Athlon 
DDR-based systems. The question now is how much of a gain in performance 
can you actually expect? Also, which motherboard should you choose? We look 
at these questions with the latest boards in the lab, the EPoX 8KHA+ and 
the SOYO SY-K7V DRAGON Plus!.
