Many people have complained about RDRAM, mainly based on its price. Now, as everyone knows, there is a good degree of parity between the prices of DDR400 and RDRAM 800. Right now, a stick of each at 256MB will run you about $2 more for the RDRAM. However, with the advent of 1066, RDRAM again soared above DDR SDRAM. So, the question is, is it worth the money? Is there a big performance difference? The answer isn't just no, it's actually hell no. Not only is RDRAM 1066 more expensive, but if you look at
this article over at Tom's Hardware Guide, you'll see that DDR400 is now the speed king. But let's be realistic, unless you're an overclocker and
need to have the fastest benchmarks in the world, you'll notice very little difference in performance. At least that article will give you a sense of security that you won't be way behind RDRAM 1066. I would also suggest that you take a look at
this article and
this article. In the first one, THG talks about the fact that RDRAM is the only memory able to take the P4 to the levels it's capable of going. But, in the second, DDR400 takes the performace crown from RDRAM 800. It's not PC1066, but the most important thing he says - indeed the thing that is most important to this post - is the fact that it's more about the chipset and its memory controller. I'm sorry for all the THG links, but they're the only articles I've read on this subject.
