AMD or Intel?

Yeah "set to be released" is really the key part of your post there, isn't it?

I'd love to know when exactly it will be released ... Anyway, my point was that RIGHT NOW, as in this month, this summer, right this second, with the choices CURRENTLY ON THE MARKET, RDRAM is the best performer. You seem to forget that SiS is releasing a new RDRAM chipset, and that Rambus is going to be releasing a new 1333MHz module, with greater than 10Gb/s bandwidth.

If the fastest DDR is at PC3200 right now (3.2Gb/s) I expect DDR2/Dual channel DDR will theoretically double that, right? If so, it's only about 4Gb/s slower than next generation RAMBUS ...

As for price, I have already illustrated that the difference is negligable... Yes, RDRAM used to cost substantially more than DDR RAM, but that is no longer the case. So the argument you posted should read: Slightly above average prices, Big Latency, Big Bandwidth= Decent sales. Or am I missing something here?

"some time early next year" is when dual channel ddr support from Intel will be introduced last i heard.

you seem to be forgetting one thing about RDRAM and Pentium 4, mavis. each speed of RDRAM is in sync with the P4 FSB, providing exactly as much bandwidth as the FSB can handle. PC800 provides what the 100MHz FSB maxes out with, and PC1066 provides all that 133MHz can cope with. unless Intel is increasing the FSB to quad pumped 166MHz or something, the new RDRAM won't help at all. i haven't seen any roadmaps or info on when Intel will be doing this. it is obvious that dual channel PC800 RDRAM cannot even compete with DDR333 single channel(the new Intel and SiS mobos), let alone DDR400(the SiS mobo). PC1066 still has them beat by a little though. dual channel DDR will change this, as it will double the bandwidth.

I second that with my own series of connected w00ts

w00t w00t!

[Kruno]

Intel = W00t 1337 cpu
Intel 2.8ghz@3.4ghz is faster than an AMD XP 2100

P4 2.8GHz isn't out yet

my 3GHz Hammer is faster than your 6GHz P5!

hmm... I have a question.

If RAMBUS delivers "exactly as much bandwidth as the FSB can handle," how will having dual channel (higher bandwidth DDR2) help in any way? The FSB will be the limiting factor still - until, of course, Intel ups their FSB, which is why RAMBUS is planning PC1333 modules with 10Gb/s bandwidth ...

Second, I should hope the new DDR333 and DDR400 SDRAM can beat the three year old PC800 RAMBUS!! lol

As I've been saying, RDRAM has higher latency than DDR on random access.
This is why it performed horribly compared to SDRAM on a pentium 3 system, where the extra bandwidth doesn't even come into play.
Now you're seeing where it obviously does come into play, and the single channel DDR can't keep up. Dual can, however, not with bandwidth, but with the reduced latency.

Sorry if any of this is patently obvious, but...

AMD is simply more for your money, nough said

although I must say, that 1.6a P4 sure does overclock like a motha!

Yes and yes.

But it's amd for me, next box.

Ive used intel all my life, it will be hard to switch.

Intel said a while back that the Pentium 4 will reach 11 ghz in its lifetime. Lets see if AMD can last long enough to compete with it.

You never DID send me those benchmarks from your system?

Check ur PM

well, single channel DDR is not getting the job done so to speak. DDR400 only provides as much bandwidth as dual channel PC800 RDRAM. obviously the 133FSB P4's can handle more bandwith than that.

second, they would come out for the same reason that DDR333 and DDR400 chipsets for AMD come out. marketing reasons purely. DDR333 offers little to no benefit, since DDR266 already saturates Athlon's FSB. DDR333 offers very minuscule benefits, although i'm not sure whether this is totally attributed to improved memory controllers in the new motherboards, or whether DDR266 only really provides say 99% of the bandwidth that the FSB can handle(due to the nature that a 10Mb/sec network won't ever transfer at 10Mb/sec).
