AMD fits two RV670 chips on its upcoming high-end graphics card to compete with NVIDIA's top dogs

AMD recently took another stab at closing on NVIDIA with the announcement of the R680 processor -- an ultra-enthusiast component assured to woo the headlines of even the most ardent reviewers.

The AMD Radeon HD 3870 X2 is two RV670 GPUs "Crossfired" on a single board, and it is AMD's first corporate-sanctioned attempt at a dual GPU card after the failed ATI Rage Fury MAXX back around the turn of the century. Many would claim the Rage MAXX was too little, too late and too expensive.

NVIDIA showcased its dual GPU offerings more recently with two separate chips on dedicated PCBs, sandwiched to form the 7950GX2. The design worked as two of these graphics cards could be used for a Quad SLI setup, but like the Rage Fury MAXX, the cost/performance ratio just didn't attract sales outside of a few hardcore enthusiasts.

AMD aims to improve its lineup with the Radeon HD 3870 X2.  FPS Labs took the chance to put the card to the test against current generation cards.

In short, the Radeon HD 3870 X2 keeps up with the likes of NVIDIA's 8800GT SLI setup and an 8800GTX single-card setup. It does outshine the rest of the cards on the list in the DirectX 10 Call of Juarez  test, but in little else. The HD 3870 X2 received a 3DMark06 score of 13852 while NVIDIA's 8800GT SLI came in at a close second with a score of 13463.  FPS Labs used ATI Catalyst drivers 7.12.

In the end, AMD looks like it has done a better job with the Radeon HD 3870 X2 than it did with the Rage Fury MAXX as the card's price and performance match up with NVIDIA's latest offerings.  With NVIDIA's newest just around the corner AMD has its work cut out for it.

The Radeon HD 3870 X2 is currently listed at various online retailers for around $400, which is more than the retail price of NVIDIA's 8800GT but well under the $500+ price range of the 8800GTX. 

AMD's embargo ends tonight at midnight, but various other publications that hold no NDA schedules can purchase the card and write about it.

Bottom of the first page in the linked article.

The Radeon HD 3870 X2 on the bench today is a very early sample of the card and the drivers even more so. That’s not to say the numbers you’re about to see aren’t accurate, it’s just we wish we could have tested it closer to launch with proper software support.

Its launching tomorrow - so its safe to assume that this review was carried out quite some time ago. Did it even have the CrossfireX driver?

If your going to quote numbers, you HAVE TO qualify them making clear reference to the (immature) drivers used. Anything else would suggest ulterior motives.

Found this:

the driver we managed to download from the AMD ftp was an early build of what we believe wound up being Catalyst 7.12.

The last Catalyst release was 8.1 on the 17th of Jan.

I see numbers HERE on the Dailytech article without any sort of qualification.

As I said - if the numbers are going to be mentioned here, and conclusions drawn, the fact that immature drivers were used simply has to be mentioned.

fps mentioned the drivers, twice. The DT article has not.

Most people who would buy a product such as this are Enthusiasts, thus they generally do keep drivers updated.

those numbers are not correct, this is:

for the default 3DMark06 test, the Radeon HD 3870 X2 managed to produce a score of 18,467, whereas the 8800 Ultra only musters 14,197. Push the resolution up to 2,560x1,600 and the Radeon HD 3870 X2 scores 12,578 versus 8,746 for the 8800 Ultra.

here is a proper review using catalyst 8.1 with pictures its to english translation via google enjoy:

i dont think fps is a fake review but they were usuing dated drivers and i think the score isnt that impressive because 7.12 wasnt really taking advantage of the dual gpu, catalyst 8.1 seems to work massivley better and the funny thing is that its been held back because amd wants to create a driver for better performance, so come next week the performance numbers will probably be even better.
another thing to ad is that 3870 at fps is using gddr3 and im sure ive seen some with gddr4?? not 100% tho.
always check the chinese sites because they usually do the reviews/previews before anyone, they do real reviews not just telling lies to make there site look good.

I wonder if in the future we might see a variant with a 512-bit interface (times 2) and up to 2gb of gddr4 mem. probably over kill but if they build it...


RE: C'mon guys, this is not good enough!

the 512-bit interface was overkill for single core gpu's, i think they will bring back the 512-bit interface when they start using multicore gpu's, i dont think it would help much having it on 2 single core gpu's but for multicore they will probably need that extra bandwidth.

does anyone know if r700 will be another dual gpu or multicore gpu????

Multicore.

Single high-end card will use 4x R700 (RV770 presumably) core architecture. Last I read DAAMIT internally tested RV770, which performance is significanlty higher than the RV670.

Like in CPU scenery, multicore a.k. parallelism is the future.
So, not only parallelism in amounts of shader arrays, but also in core chippery.

This HD3870 X2 is a step-up for DAAMIT, the bridge to multicore. By watching news and articles, I firmly believe DAAMIT is much more advanced at multicore/Crossfire than nVidia...

You are not looking at the bigger picture... The test system used at the Chinese site was much more powerful than the one used at FPSLabs. That system had a QX6850 running at 3.6GHz, (not to mention 1600MHz FSB), whereas the FPSLabs system was running a QX6700 at stock (2.66GHz, 1066MHz FSB). The memory in the Chinese system is also significantly faster.

You are quoting 3DMark06 scores that are very dependent on CPU frequency, you don't have to look further than overclocking your own system to see evidence of this.

yes i agree with that but both card were benched @ 3.6, i can see your point tho about a lower clocked system.
but fps should have used a mature driver that works better with the card, im just waiting to see the results with the proper driver for the card it should be even more impressive then.

Well, the card was tested on their site on December 21-22, so using Cat 8.1 or later was not an option. The review was held back for a full month due to AMD's NDA, and AMD did not provide them with updated drivers while the card was in FPSLabs' possesion.

I just take offense when you say the numbers are "not correct" because they most certainly are reliable and also in-line with what other websites have produced.

I agree with you that the performance will increase with more mature drivers, and IIRC that point is stated multiple times within the article at FPSLabs.


Looks good, but doesn't sound so good.

I'm considering this as an upgrade option. However I must admit to being a little scared off by it's ability to drown out a passing train with it's decibels...

i'm not too concerned about its noise level but its size. It looks huge. I don't think it'll fit in any of my cases.

i only really looked at the first pic after i read your comment...

the card looks friggin massive!!not a chance of fitting in any sub 100$(aud) case...

from the pconline pic its not any longer than the ultra

Hopefully, Arctic Cooling will come out with a compatible cooler for the dual-chip Atis & Nvidias. I have an Accellero S1 on a 1900xtx and it is very quiet, lets me overclock it, and keeps it cooler than the stock hsf to boot. It's a pity ATi doesn't learn a few tricks from the aftermarket vga cooling manafacturers they'd sell more cards.

Only, if graphics cards really do go multi gpu with the release of D9e and R700, these aftermarket manafacturers are going to have a hard time making a one cooler fits all with multiple gpus in varied places.
