Tomshardware's Behind The Silicon Curtain: P4/2666 With 533 MHz Rambus

Here's a nice quote:

"Our benchmark results clearly prove that if Intel changes the FSB and memory clocks (to 133 MHz and 533 MHz, respectively), this will put it quite a distance ahead of its competition from AMD, as well as its own series of processors. In the Office Performance category, the Pentium 4/2666 with 533 MHz RDRAM soars about 50% above the fastest AMD Athlon XP 2000+ (VIA KT333 platform and DDR333). In MPEG-2 video encoding, the Pentium 4/2666 is approximately 25% ahead of the AMD Athlon XP 2000+ (VIA KT333 platform). What's more, the P4 2666/533 achieves higher benchmark results than a P4 3000/400 in some categories ."

"Our detailed tests show that forthcoming P4 CPUs with 133 MHz FSB clock used in conjunction with the 845E chipset (DDR SDRAM support) will effectively be castrated."

The bad news: We have to wait til late July before we will see the 2.53A...and October for the 2.66A. 🙁
The good news: The 2.0A and 2.2A are dropping in price in a few months (late April, again in May), and we can always overclock. 🙂

Is anyone else looking forward to running their PC1066 RDRAM at PC1200+ speeds, like I am?
 
I just slimed through it!!!

All i can say is :Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q
:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q

It seems like today's processor is highly limited by memory bandwidth...
maybe if there is a chipset that paris RDRAM with AMD XP+...wonder what it will be like

I still won't switch to Intel until 0.13micron shows up with AMD, then I will decide

but still :Q:Q:Q:Q:Q:Q:Q
:Q:Q:Q:Q:Q:Q:Q:Q:Q:Q
 
I believe he's got it pretty well on the mark🙂............except that we'll see a 533FSB P4 2.4 by mid Q2 according to Intel itself.........and certain others.....😉
 


<< Aces hardware did a 'preview' of this a few months back >>

Yea, except that his platform was Williamette not Northwood, but yea his article was great.

This proves what I have said all along about Abit TH7II. The only thing (he's not the only one) is that he didn't test 533fsb+PC1066 to 533fsb+PC2100 to show the difference that really exists betweeen PC1066 and PC2100!!!:disgust::| oh well. I'm reading now.
 
Damn! That's impressive. Comparing it against the Athlon 2000+ is pretty moot though as we already know that the .13um Tbreds will be out and about. I think the Tbred may have a hard time with the Northwood at 133Mhz if it stays on the 133Mhz FSB, which by all indications, it will. If that's the case, AMD won't have a performance leading processor until Hammer. :disgust:

Active cooling for the RIMMS sucks though!

 
Wow! Impressive speeds for certain. Anyone know how much PC800 RAMBUS can reach PC1066? No overclockers vendors are selling any guaranteed stuff, maybe a market for it could be emerging? With that, the performances shown there would be pretty easily achieveable for something like the 1.8A with a TH7-II.
 
So can anyone tell me what the difference between us OC'ing 100Mhz P4's to 133 (and beyond) now, and P4's running on Intels official 133MHz bus is? Other than the obvious P4-100 and PC800 'out of spec'. Aren't Northwood OC'ers effectively getting this kind of speed now?
 
Strafe, if their using RDRAM at 133mhz then yes their speed should be the same as the 133mhz P4's in Tom's test but most people are using DDRAM which isn't as fast as RDRAM.

Hopefully mobo makers will update there i850 boards when the 133mhz P4's and i850e are released. I would kill for a i850e motherboard with USB2.0, Firewire, ATA133 RAID and 6 channel hardware sound.
 
"The bad news: We have to wait til late July before we will see the 2.53A...and October for the 2.66A."

From Tom's article:

"As of today, we have already tested the processors that Intel won't be bringing you until the fall of this year, at the earliest."

That says nothing about the release of the 2.4, but would seem kind of odd that they would release a 2.4 in mid 2nd quarter than wait 3 months or more to release the next speed grade.

Those new CPU's look most impressive. AMD better be looking at that and realize they need to start releasing higher speed grades more rapidly than once every other month. They had a strangle hold on the performance crown back when the 1900+ was released, but it is clear Intel is getting their act back together, while AMD seems to have lost some of its momentum. Here's hoping the Thoroughbred can level the playing field a bit.
 


<< Anyone know how much PC800 RAMBUS can reach PC1066? >>

Generally, Samsung/Corsair PC800 RDRAM will hit PC1066 speeds without active cooling. I have no idea why they felt it was necessary to have active cooling.

<< So can anyone tell me what the difference between us OC'ing 100Mhz P4's to 133 (and beyond) now, and P4's running on Intels official 133MHz bus is? Other than the obvious P4-100 and PC800 'out of spec'. Aren't Northwood OC'ers effectively getting this kind of speed now? >>

There is no difference really. I mean, the Th7II has 1/5 PCI divider so at 133fsb the PCI bus is still in spec, so really there is no difference. And yea, Northwood 1.6A's with Retail HSF hit easily 133fsb and with better HSF's, 1.8A's ca hit 133fsb as well😛

<< Hopefully mobo makers will update there i850 boards when the 133mhz P4's and i850e are released. I would kill for a i850e motherboard with USB2.0, Firewire, ATA133 RAID and 6 channel hardware sound. >>

I too wish this would happen. Hopefully, Soyo is jump starting this. I read a AT Press release about Soyo boards to be announced at CeBit and one of them was the P4I RAPTOR which looked just like a P4I DRAGON except, it uses you guess it, 850😀😀😀😛
 
According to the "Intel Press Room" updates the P4 2.4 @ 533FSB is still on schedule for late May....................😉
 
Of course the P4 533FSB is gonna be faster than a Athlon XP 2000+. Thats 1GHZ clock speed increase. I guarantee an athlon xp @ 2.67 would smoke any p4's.
 
I didn't see any mention of these CPU's in Intel's press release section going back a couple of months, nor does intel go into enough detail in their roadmaps to announce late May (the only one I found on their site had 2nd half 2001 and 1st half 2002), but I did dig up the info at X-bit. They're saying a 2.26 and 2.4 in 2nd quarter, 2533 in 3rd quarter and 2.66 in 4th quarter which would make sense. Tom on the other hand has a different roadmap.

"The Pentium 4 that is to be introduced with 2.4 GHz at the beginning of April will need a performance boost that is more substantial than those of the previous models in the P4 series. At mid-year point, it will be followed by the Pentium 4/2533, which will be the first CPU with a 133 MHz FSB."

So Tom is saying that there won't be a 133MHz 2.4, just at 100MHz. I would guess there will be, but it might be the same as it was with the original P4 where the 1.5 was released before the 1.3. Of course Tom then says later that it won't be until fall at earliest. Around here fall doesn't come in the middle of the year, so it seems that Tom is a bit confused. Either way, I would think Tom's schedule has been updated a bit more recently, considering he just got the chips and platform. We'll see. AMD better hope the more optimistic roadmap is not the true one.
 
There are lots of news articles with reports on Intel's roadmap; xbit labs isn't reliable, they just take their news from other sites. The TehamaE (850E) with 533FSB will be released the week of May 20 along with 533FSB P4 2.26 and 2.4. The P4 2.4A may or may not be released in a 400FSB version the prior month (April). The PC1066 RDRAM parts from Samsung, which you see listed on Tomshardware's page, will be released at the same time as 850E launch.

We've discussed this over and over, and linked to articles before. There is no need to rehash it. Just accept it as fact, cause that's what it is. 🙂
 
I really wish AMD would ramp up their chip speeds! I'm amazed that a chip from intel that is 1 ghz faster can only have a marginal increase in performace when compared to the XP2000+. If AMD could get TB up to current p4 speeds, Intel would be in the dust. 🙁
 
I dont disagree that those numbers are impressive, but look at those numbers then do the $$ to performance ratio and AMD is still the better choice.
Who REALLY uses that power ? Not anywhere near the majority of us will ever touch that highend need...
 
We have no idea what the price performance ratio of those Pentiums will be because no one knows the price. From a technology point of view it's pretty awesome, no matter whose cpu is in your current system.

How is XBitLabs "not reliable", and name one other site that you would trust more that actually has any info on Intel's future roadmaps.

Btw, where do you get the idea that this is "fact"? Did Intel themselves say that "850E will be released the week of May 20th"? Or that "533MHz FSB P4's will be released the week of May 20th"?

As for the results, did anyone really find this surprising? Cmon, a 1GHz speed advantage, 533MHz FSB, and RDRAM versus a 2000+ Palomino with unofficial PC2700 DDR. No competition. But it means nothing if Intel isn't going to release until the fall. And from what Tom said, it might be longer than most roadmaps are claiming currently.

Not to take away from these amazing scores, but the bottom line is that by the time a 533MHz FSB 2.66GHz P4 dubuts, we could easily have 2GHz+ Bartons.

That highend speed is what many of us already get now with a $140 1.6A overclocked from 2400Mhz to 2650MHz. 🙂 Of course, you need RDRAM too...to compare to Tom's results.
