I notice that P4 memory benchmarks under Sandra are unbeatable , even with Athlon T-bird + PC2100 DDR ram.

Can anyone share some light on this matter?

So when is AMD releasing QDR (Quad Data Rate technology)?

 

[John]

RAMBUST owns You !

Bigger pipeline.

 

[Vegito]

I dont think amd owns QDR so they would have to wait till it's out or join in the developement of QDR..

 

[noxipoo]

QDR or DDR isn't put out by AMD. p4 needs that high bandwidth to come close in terms of performance to the athlon. its sad.

<< p4 needs that high bandwidth to come close in terms of performance to the athlon. its sad. >>


I think the P4 was designed around the fact that they will have the big bandwidth of RDRAM.
Kind of like how using DDR SDRAM on the 1 GHz Thunderbirds didn't make too much of a difference over normal SDRAM. The Thunderbirds were designed around the bandwidth of memory at their time.

 

[JorgeElPrimero]

It just has higher memory bandwith.
Simple as that.

QDR is suppose to be released in quarter 4 of this year. Looks like Micron, Cypress, IDT, NEC, and Samsung are all working on this together. Kindof kills the idea to upgrade to DDR now.

Imagine someone comes out with PC4200 and PC8400 DDR ram !!!!!

 

[odog]

it's not the rambus per say, it's more the fact that the P4 has a 400mhz FSB.. we all know that dual channel rambus, isn't all that matters(just check some i840 mem benchs)

 

[Wingznut]

But if you were to couple DDR or SDRAM with a P4, you wouldn't see nearly the same results. And if you stick RDRAM with a P3, you'd have no improvement over SDRAM.

So no, it's not directly the RDRAM... It's the whole package.

 

[Dewey]

P4 memory bandwidth is amazing. To bad the overall performance and value are terrible.

 

[Rand]

look at the P4's memory subsystem and you'll see why.
A 400MHz QDR FSB tied to dual channel PC800 Rambus makes for an incredible amount of raw memory bandwidth.

 

[NFS4]

I think that you people are all crazy for relying on Sandra benchmarks. They mean NOTHING in the real world. You're just being brainwashed just like 3DMark 2001.

LET IT GO!

 

[Jgtdragon]

I agree totally with NFS4!
Sandra and 3dmark are only good for comparing tweaks to your own system.
Kinda a before and after comparison with tweaks or overclock.

 

[NucleusWDS]

So what's a good benchmarking software? ..... SysMark 2000?

 

[Sir Fredrick]

Well said NFS4. Sandra is suck.

 

[joohang]

I never trust a hw review site that relies on Sandra.

I only use it when I want to monitor my CPU temp once in a while without motherboard monitor handy.

Looking at the fact that even current DDR's bandwidth doesn't do much with today's benchmarks, I don't see the point of QDR any time soon. I guess I'll be happy if they release one before the end of next year or so.

 

[Sunner]

Well, while Sandra isnt very useful to most of us(at least not that part), it is a fact that the P4 has an incredible memory subsystem.

Thats why it kills pretty much everything, save for some Alpha's, in SpecFP 2000.

It just doesnt matter a whole lot to most of us.
