rdram vs sdram

By steve.schulmeyer ·
I am considering a new pc. PIII's still use the sdram and the P4's have rdram. What is the benefit and cost differences in the memory between the two processors. Is it worth moving beyond 1.1mhz PIII at this time?

rdram vs sdram

I can only offer my opinion, which is to stay with PIII. Rambus is highly over-rated (and some say will be obselete soon anyway), and can actaully cause performance degredation because of the latency. In any case, I don't think it is worth the extracost and hassle right now. Maybe when p4 supports DDR... I went through the same thing when buying my last CPU and I went with PIII 1 GHz. Couldn't be happier. Hope this helps!

In addition to the above comments, sdram runs at 33-133 Mhz, Rdram runs a 600 or 800 Mhz. That is a little deceiving though because rdram actually runs at half of it's rated speed but in striped sets across a pair of chips (oh, by the way rdram must be run in identical pairs). As far as actuall performance, remember that software is just becomming optimized for PIIIs, very little is optimized for the P4 yet, so it's a little to early to tell, some tests indicate strong potential, others lean toward simpler, cheaper ddr memory. Sorry this is a little fuzzy, I guess if I had to give a definative answer, it would be to wait a while.

Intel has said that they will produce a version of the p4 this or next quarter (if on time) that will support sdram. RDRAM is ok, but I wouldn't say it is spectacular, and to agree with the others it is rather costly. Whether it is worth it to move to a p4 is dependant on what you are using it for. If you are just doing word and excel probably not, most computers PIII's included will do the job. P4's run at higher speeds as you can see when shopping for computers. Maybe look at AMD chips also, they are good and run at higher that 1ghz speed and I believe they support sdram and ddram.

If you're looking for a worthwhile move, I'd definitely wait. 1.1Ghz isn't anything to laugh out, unless you work for LucasFilms.

The highest you could go now is 1.8Ghz, which is overkill and required a PIV ready setup. The current "version" ofPIVs is gonna be thrown out the window pretty soon in exchange for a new die-size for the PIV.

RDRAM may have a bigger bus, but latency is and always will be a problem with it. The initial issue with Rambus was the exorbitant cost of a stick of RAM and the notorious deal Intel and Rambus struck up. In my opinion, it performs pretty damn well now and I could care less about the deal, but DDR is a bit cheaper and performs about the same.

There's more to the story, but I doubt you'd wanna hear it. Besides, spending enough time in any forum will assure that you'll hear takes on the AMD vs. Intel battle.
