Rambus PC800 (RDRAM) vs DDR PC3200

[whattaguy]

I know that back when Rambus came out, it smoked DDR. But a couple years later, DDR came a long way. Which is faster?
I couldn't find any bechmarking side to side.

Thanks.

The oldest AnandTech i865 / i875 chipset articles probably include at least i850 PC1066 in the comparisons against dual channel PC3200. As I recall PC800 beat DDR PC2700 single channel.

Edit: yep, PC3200 DDR dual channel vs. PC800 RDRAM in the AT i875 chipset article

and from the looks of that comparison, the 875 and 850E chipsets running the same spped CPU are virtually equal..and the 875 CPU's use a faster bus (800 vs 533). If there was ever a RDRAM chipset that supported 800fsb CPU's (and faster RDRAM memory), it would have been ,no doubt, still be the fastest platform. But as we know now, the rest is history.

That's why I still like my PC 1066 rig on the I-850E chipset. It will last me another year for sure. It was expensive at the time though.

I miss my D-850MV motherboard, I was using PC-1066 RD-RAM on that. RD-RAM feels much faster, I really don't know why (im using DDR-400 on an a7n-8x now).......

I was asking, because I'm moving from a

P4 2.4B (533fsb)
1 gig RDRAM PC800
Asus P4T5333-C Mobo

to a

AMD64 (754) 3000+
1 gig DDRAM PC 3200 (CAS 2-3-2-5)
DFI Lan Party UT NF3

I know that the AMD will smoke the first setup, but will there be much difference if I moved to a P4 3.06 with HT (533fsb)?

 

[Comparisonman]

You'll notice the difference with the 3.06 HT, but the AMD64 with be even faster than that.

It?s a shame that SiS r659 never made it in to production
A quad channel pc1200 RDRAM would have man handled fastest DDR even today

You guys are awesome! Thanks.

 

I wish RDRam would make a comback. Such good tech! The faster it got, the lower the latency...it was wonderful!

I agree. I was bummed when ASUS held back the production of the new RDRAM board that implemented all of the "new" goodies.
