P4 2.4Ghz 600Mhz FSB PC-1200 RAMBUS!

[SSXeon5]

Link!

Good artical about some i guess early samples of RDRAM PC-1200 and DDR PC-3200 .... the PC-1200 did great but i still want to know how tom always gets things before anyone else does ... like the 533MHz P4's he has and now PC-1200 RDRAM ..... i really want his job

Notice the i845G out performs the sis645DX and the i845E .... the intel chipsets beat out the sis chipset by alot ... the i845G with 166/333 CL2 beat out the sis645DX by 52 frames in quake 3!


If PC-1200 is out when the B's come .... I will really concider it because it will even have more bandwidth then granite bay (my long awaited chipset ) having 4.8GB/s compaired to granite bay with 4.2GB/s .... but thats only if they have the 32-bit RIMM4200 and 32-bit RIMM4800 when the B's hit.

here is the start of the review:

Great Catch SSXeon!

I'm a little confused, what FSB was the P4 at? Was an overclocked 1.6a at 2.4 with 150 MHz QDR FSB? I guess with motherboards that have the option to lock the PCI/AGP bus, the only limitation is the memory and processor. Any idea when these RDRAM modules will come out?

And people want to use DDR rather than RDRAM in their 2.4GHz systems. Please, don't insult your own intelligence by doing that nonsense...

well DDR does have better performace when clocked the same as RDRAM .... and its only if They DO launch the PC-1200 32bit RIMM4800 when the B's come. Granite bay (duel channel DDR266) will perform wayyyy better then a i850E chipset with PC-1066 RDRAM. But thats only if the RIMM4800 arnt more then PC-2700 ...... that i will concider it at thins point ...

Look at it this way, when you use RDRAM you unlock a few speed grades worth of performance in comparison to a DDR-based system. The DDR systems are in single channel. The 8-bit RDRAM and the 850E chipset were clear leaders when comparing PC800 to PC2100, PC1066 to DDR333, or PC1200 to DDR400. We'll see even better performance once the 16-bit RDRAM modules surface.

Really? Check the link below. Over 3000 in SiSoft Mem bench on my i845 DDR 2.4 GHz system. Not quite RDRAM level, but pretty darn fast.

 

[Clevor]

So it does look like PC-1066 and PC-1200 are on it's way (me drools). I also believe they should be backward compatible with PC800 motherboards (the 32-bit would allow just one chip to be used?).

That would allow me to run 150 FSB/4X stable on my P4T-E. Actually I am doing 144 FSB or PC1152 right now so that would already put me second from the top on framerates in QuakeIII (talk about a head start). However I do get flaky software install issues, but 3D is pretty solid all around.

That Sandra memory mark for PC1033 seems a bit inflated though. Most guys quote around 3300. I get 3583/3551 and I'm at PC1152.

Quick question.

is the i845G that tom used a dual channel ddram board?

 

[68GTX]

"is the i845G that tom used a dual channel ddram board?"

No, the i845-G Mainboard that Tom used was a Gigabyte GA-8IEXP with a Brookdale-G Chipset.

 

[ntrights]

Ok thx! When will we see a dual channel ddr mobo for the P4 (similar to the nforce board)?

 

[68GTX]

"Ok thx! When will we see a dual channel ddr mobo for the P4 (similar to the nforce board)?"

The following information is from the 2002 Roadmaps at MikesHardware.co.uk

"VIA P4X600 chipset for the Pentium 4 processor is expected to be released in Quarter 2. The P4X600 will be based around the P4X333, but is expected to support dual channel DDR SDRAM (previous rumours suggested QDR SDRAM support instead (Quad Data Rate, implemented by operating 2 banks of DDR SDRAM - on a single DIMM - at a 90deg phase to each other), but this is unlikely). The VIA 8235 South Bridge features support for USB2.0 and ATA133."

"Intel Granite Bay chipset for the Pentium 4 Northwood (and single processor Prestonia is expected to be released in Quarter 3. Granite Bay is expected to feature 533Mhz FSB support, dual channel DDR200/266 DDR SDRAM (giving a memory bandwidth of 4.2Gb/s), AGP 8X and Intel's ICH4 South Bridge."

"SiS 655 chipset for the Pentium 4 is expected to be released in Quarter 3. The SiS 655 is the successor to the SiS648, featuring support for Dual Channel DDR SDRAM. The SiS 655 supports both DDR266 and DDR333 SDRAM, giving memory bandwidths of 4.2Gb/s and 5.4Gb/s respectively. The SiS 655 will feature a 1066MB/s link to the SiS 963 South Bridge which offers support for ATA133, 3 x IEE1394 and 6 x USB2.0 ports."

Also, keep in mind that future roadmaps often change.

 

[ntrights]

Kewl, I will wait for those dual channel ddr boards before my next upgrade (which will most likely be SiS 655 and DDR333 5.4Gb/s, provided it will be a good overclocker ofcourse) Thanks for the info 68GTX!

Does anyone have any more info on this??? (links,reviews or anything)

Never did like Tom's way of seeing things.

The intro has a title of...

DDR400 vs. RDRAM (PC1200)

Then, he puts the conclusion title as

DDR 400 Beats RDRAM (PC800).

The conclusion should answer his initial question/challenge which pitted DDR400 against PC1200 (not 800). Someone just skimming could come away with the wrong conclusion.

So basically, he is comparing a DDR module not yet available (can't find it in stock anywhere), with a current generation RDRAM module in his closing statement. On top of this, he uses a CL2.5 module which is even further away than the CL3 ones.


I guess he is one of those who is against RDRAM even though the PC1066/1200 wiped the floor with DDR400.

Tom's Hardware in my mind is a joke... for this and many other reasons.

It's hardly as clear cut as that. Based on currently available chipsets, DDR333 on the SiS645 chipset competes very well with the I850 paired with PC800 DRDRAM. Indeed, in some instances in even performs better.
Even the I845D which based on most available reviews generally performs slower then the VIA P4X266A, and SiS645 w/PC266 DDR is hardly a "few speed grades" slower then the I850 w/PC800 DRDRAM.


Hell, the SDR SDRAM I845 chipset is usually about 3-4 speed grades slower then the I850 DRDRAM chipset.

Besides, I consider DDR SDRAM to have much brighter future then DRDRAM, and I'd certainly put more faith in the longevity of DDR over DRDRAM. Especially considering even Intel seems to be slowly moving away from DRDRAM.
It's quite interesting that even Rambus own roadmaps still put forth DDR as having a majority market share as late as 2005. Most other analysts have DRDRAM as having a rapidly decling marketshare post 2002-2003, so I hardly think it's stupid for one to consider DDR over DRDRAM.
Whether DDR is a better option or not is debateable, but I can certainly understand why many would prefer it.

One more vote from me on that-noticed but never had a good chance to post about it. Absolutely ridiculus review :disgust:
Good on you Steel!!

 

[lookin4dlz]

So, I'm not the only one who doesn't like the way Tom's Hardware reviews??

I don't intend to crap this thread since discussion of the review methodology helps people decide if the review is valid. It's not that the site doesn't have some good information & I've been reading it for years - probably since it was started. However, the reviews just aren't very objective. If you re-read some of the site's AMD vs Intel articles, they are clearly AMD biased in both wording (very negative words used to describe Intel) and in methodology (not apples-to-apples comparison) that taints the content a bit.

That's only because the i850 isn't exactly a great chipset. Once SiS releases its chipset designed for RDRAM things will change.

 

[dajeepster]

I'm glad I'm not the only one that thinks Tom hates Intel. It's really hard for me to send poeple to that web site with such a biased view on AMD/INTEL... I send everyone to Anandtech only now.

i850 is a great chipset its just the 16-bit RDRAM 800MHz compaired to 64-bit DDR 400Mhz is in favor of the DDR in performance. And I would not buy a SiS chipset EVER again after my EPOX board experiance And Granite bay will still kill sis' offering .... it has intels stability, AGP 8x, serial ATA and duel channel DDR266 (sis' duel channel DDR will only have 4x agp and ATA133 LMFAO and sis' unstable platform) I still think the i850 is a great chipset im just pissed that RAMBUS took too long for them to get 32-bit RDRAM out and the granite bay still looks like a better choice.

That is almost too obvious. Anyone who thinks otherwise is crazy. It is kindof funny how no matter what, the AMD is the better CPU. If AMD beats it in performance, it's the best. If AMD loses in performance, everyone should run out and buy it because it is less money.

And why is it that everytime he compares the two, he brings up the Mhz gap over and over and over praising AMB for for their performance at slower speeds. Even makes it part of the huge into image 9 times out of 10. Earth to Tom.. Come in Tom... no one cares about Mhz!!!
