AMD/ATI, waiting for the right moment to pounce?
It seems that PCMagazine has gotten their hands on a "special" version of the Radeon HD 2900XT in a Crossfire setup which nearly DOUBLES performance across some games and benchmarks over NVIDIA's 8800 GTX SLI.
The systems they used were direct from Falcon Northwest and so the question is... what about the rest of us? The folks over at Dailytech provide their insight into this interesting find in an editorial.

24 Comments on AMD/ATI, waiting for the right moment to pounce?
I knew ATi wouldn't let us down.
Keep in mind, the 8800GTX SLI system had an Intel quad core at 3.73GHz, while the 2900XT GDDR4 had its at 3.61Ghz. This tells me that the OEM version of the cards either have high ass clocks or Falcon NW/ATI are rigging benches (I doubt it though :p)
Why else would the OEM cards have such an outrageous cooler?
EDIT: Just saw the bench picz, the performance deltas are FKN HUGE >< ATI's prolly got some souped up drivers up their sleeves.
U mean on both the Falcon NW and the D3LL 720C?

Someone with a GTX SLI did benchmark it and found similar results here
Also note that in other forums the HD 2900XT is doing much better in Vista then the G80. Benchmarks using Vista here. As you can see the ATI arch is more efficient in running games in Vista then G80 arch is. IMHO, I don't see G80 drivers closing the HD 2900XT delta but any thing is possible.
That Falcon PC better be some of the best no matter if it was NV Sli or ATI CF, for $8,000 dollars...DAMN! That's close to 10X what I paid for my build! That's just stupid rediculous in my eyes. I know that's off topic, but every time I see an overpriced pre-built PC like that it makes me slightly angry. Sure I know Falcon PC's do a very good job, and they better for the price you pay, but I'd never pay that when I would rather build my own, tweak it the way I want and enjoy it how I want, plus I don't mind building PC's as it's not a hard thing to do!
On the ATI Scores, I think that is due to custom drivers, possibly for future release. I think the scores are just amazing. And WarEagle, I would agree about the XTX deal, but it's clearly posted mulitple times that those are XT's (or it's a large scale typo). Granted for the price of the PC, it should be XTX's. And I think if these numbers hold true to real customers of that system or similar builds, then NV will pull out some new amazing next or second gen DX10 card. The "next" thing is always on the horizon. But amazing scores none-the-less, now if we can find someone that is getting that system or building a something similar...
If this is just XT's in CF and GDDR4 with high clocks, then I'm intrigued to see the XTX's in action, and more-so intrigued to see a Pro variant that may be better OC-able than say the 1950pro line, with at least 256-bit memory, and around 2/3's the features/capacity of an XT variant. Both NV and ATI haven't released a variant in that area and I believe that gap between 8800s/8600's, 2600's/2400's is too large to overlook. :toast:
Well the HD2900XT was using crappy memory anyway so yeah so that my explain the such dramatic difference in performance.

The following is taken from the Geforce 8800 round up review on bit-tech.
This shows a single 8800GTX scoring higher than the SLI setup on the link in the op post despit being on a slower overall system.
This is obviously windows XP but just shows how bad SLI is running (or not I would imagine) under vista.
Whilst I would love to believe ATI have these magic drivers under wraps I think the difference in performance is more likely SLI not working / poor vista drivers rather than a massive performance jump for the HD2900XT.
EDIT: Just to add, the following review also from bit-tech just shows the difference (albeit on older drivers) that vista gives compared to XP for a 8800GTX SLI setup:

Here: www.bit-tech.net/hardware/2007/02/20/nvidia_geforce_8800_series_round_up/8
However I have also found the following: (a much newer review of a 8800Ultra that shows 8800GTX sli scores against a HD2900XT CF setup)
Company of Heros
The bottom graph (for some reason I can't get the graph to load as an image here) clearly shows the 8800GTX SLI setup scoring above 90fps with 4xAA and 16xAF at a resolution of 2560*1600. Considerably more than the 37fps per the op post benchmarks. (its also higher than the HD2900XT CF setup)
Prey
Again the bottom graph is the one to look at. This time its 65fps per the Op benchmarks and 88.5fps for the Bit-tech review (the latter also includes 4xAA and 16xAF whereas the Op benchmarks don't state whether any is running)
There are no Synthetic benchmarks run to compare 3dmark06.
This is running on Vista Ultimate with the following setup:
Intel Core 2 Extreme X6800 (operating at 2.93GHz -- 11x266MHz); Asus Striker Extreme motherboard (nForce 680i SLI); 2 x 1GB Corsair XMS2-8500C5 (operating in dual channel at DDR2-800 with 4-4-4-12-1T timings); Seagate Barracuda 7200.9 200GB SATA hard drive; Enermax Galaxy DXX 1000W PSU; Windows Vista Ultimate x86; Nvidia nForce standalone drivers version 15.00 WHQL.
So this system scores going on nearly 3x as high as the one in OP post despite being on a slower system overall (stock X6800 vs overclocked Quad core).
Thats says to me something was wrong with the SLI setup in the OP post benchmarks as the difference in results just isn't right
Also I take back my comment that the nvidia vista drivers suck if the bit-tech review is anything to go by they arn't too bad.
One thing I will note however from the bit-tech review is just how well the HD2900XT scales with CF in comparison to either the 8800GTS and the 800GTX at higher resolutions.
-that the GTX is beating the Ultra in SLI by a wide margin, showing something a miss
-the R600 CF still beats the GTS in the majority of the test using Cat 7.5 (currently we are on Cat 7.6).
-This is the R600 512Meg not the 1024 version.
You can't just say "look, look at this benchmark results of the GTX..." when it's clear that how it should perform (ultra, GTX, GTS...in that order) is not whats being shown (when other reviews show this exact trend. At this point, it's hard to validate the GTX SLI performance results at this time.
In the bit-tech review there are no Ultra SLI results only single Ultra cards. I only posted the review of the Ultra as it had GTX SLI results in it.
The GTS vs HD2900XT has nothing to do with this thread, the point is about the GTX results in the first OP post benchmarks being off by quite a bit.
Here let me help you: Link. If you go to their review it will take you to the link I posted above.
