Ati HD4870X2 CF scoring X12515 in Vantage?

@ 2008/06/18

Browsing through hardware enthousiast forums sometimes gives people an advantage, in this case results of a HD4870X2 CF setup scoring X12515 in 3DMark Vantage. Please note that this result still has to be confirmed!

I didn't notice Massman already posted this; oops

most sites used the Vantage Performance setting; couldn't find many who used the "X"

that GTX 280 score is from the Zotac AMP card, which comes pre-overclocked on all fronts (quite decently OC'ed actually).

A tiny bit more info here: http://www.ocxtreme.org/forumenus/sh...ad.php?p=44949

For reference a single GTX 280 on a 4Ghz Quad Core system scores 5368, two HD4850 in CF score 5132

In a perfect world where performance scaling is without overhead, one HD4780 would score 3128 vs a single HD4850 2827, most likely it will be a bit higher.

It is not just 3DMark Vantage that RV770 holds the advantage.

GTX 280

Single Precision: 933MFLOPS
Double Precision: 116MFLOPS (Not sure on this number)

RV770

Single Precision: 1TFLOP
Double Precision: >200MFLOPs

All numbers except the one I noted come directly from each company.

Anyone that has seen GTX 280 running Folding@Home will understand... I'm seeing a single GTX 280 geting about 5,500 PPD. If RV770 can outfold GTX 280 as the above numbers suggest, then it will be a huge coup d'état for over 50% lower price.

at the end of the day I prefer game benchmarks to compare performance, 3DMark comparo between NV<>ATI has long been not representative for real world game performance.

FudZilla confirms some more Vantage scores:

Quote:

ATI's soon-to-be-launched dual slot, Radeon HD 4870, will score 12600 on a Q6600 based system. We are talking about default 1280x1024 3Dmark06 score. Radeon HD 4850 scores around 11300 in the same benchmark at the same settings and if you get the resolution to 1920x1200 and use 8X FSAA the score drops to 7200 points. Radeon HD 4870 scores 9000 at these settings in 3Dmark06 and 7700 points in 3Dmark Vantage default settings.

Radeon 4850 scores 6400 in 3Dmark Vantage default settings and it drops to 3680 points when you crank up the resolution to 1920x1200 and turn the anisotropic on. Radeon 4870 scores close to 4600 points at these settings. Overall, Radeon 4870 looks 10 to 20 percent faster than the GDDR3-based 4850 and you should even get playable scores at Crysis at 1920x1200, but of course No AA.

Not so sure what to think of it, really, but I hope this score is correct

While we are away for Computex, CJ let us know that the Radeon HD 4870 X2 R700 prototype card is out and it beats the NVIDIA GeForce GTX 280 in 3DMark Vantage. The R700 card is basically made up of two RV770 GPUs with 2x256-bit memory interface to either GDDR3 or GDDR5 memories. We asked our sources about R700 in Computex and apparently AMD is going to let AIB partners to decide the specs themselves. Therefore, the partners will set their own clock speeds, PCB design, memory types, cooler solutions etc. and there will be Radeon HD 4850 X2 and 4870 X2 cards differentiate by the memory type. The R700 card apparently doing pretty well at this stage scoring about X5500 in 3DMark Vantage Extreme preset while the GeForce GTX 280 card is scoring X4800. Both sides are still working hard on optimizing their drivers for the new architecture so probably we will see the performance to improve over time.

What does GTX 280 score at that setting?
