ddr vs sdram

[fetuchin]

i've been told that using an a7v133 with pc 133 sdram for a 1,33 athlon is nonesense compared to ddr performance. Is it really true? 'cause as i think i have read in this forum ddr only outperforms sdram by just a little factor from the practical point of view.

so far, just a fraction, but eventually as the technology develop or as the chipset advances, it will be better used.. certain test shows a greater benefit..certain one doesn't..

Expect a 5-15% performance boost when using DDR on the Athlon. The reason why the gain isn't higher is two-fold. First of all, the Athlon (at least the Thunderbird) doesn't take full advantage of the increased memory bandwidth. Secondly, being a relatively new technology, chipset manufacturers are still trying to figure out all the in's and out's of DDR to get the most performance out of it.

Basic rule of thumb: if you're buying new, buy DDR. If you're upgrading a relatively new system, stick with SDRAM and save yourself the money.
