Introduction

Four months ago, ATI officially announced their first multi-GPU solution called CrossFire.

Two months ago, we previewed and benchmarked it.

And today, ATI lifted their NDA on CrossFire performance with the Radeon X850 XT.

Contrary to what we were all led to believe, CrossFire cards are still not available, so today, we have little more than what we had two months ago when we previewed the platform.

Obviously, drivers have improved tremendously since we first benchmarked CrossFire, but as you will soon see, the platform still isn't entirely perfect. You will also find that CrossFire performance is decent, however plagued by an unfortunate GPU limitation limiting current CrossFire setups to a 1600 x 1200 maximum resolution.

The timing of today's NDA lift is curious at best, given that ATI's next-generation GPUs are literally just around the corner. In fact, given things such as the current 1600 x 1200 resolution, we honestly wonder why this performance introduction wasn't delayed until ATI's R520 launch.

Meanwhile, NVIDIA has steadily been improving the quality and availability of their SLI platform, which was announced over a year ago. Across the vast majority of their product lines, ATI is playing a seemingly never-ending game of catch-up. From the delayed release of the R520 to CrossFire, things haven't been looking up for ATI. Let's see if the trend continues here today.

article problems? by bobsmith1492, 1597 days ago
I'm assuming the article is brand new and yet to be fixed, but in case no one has noticed, the charts on page 4 show the crossfire consuming no power. While I'm sure that would be everyone's goal, I don't think it's right somehow.

That limited resolution and refresh rate is going to the achille's heal of Crossfire.

If this had been released 6 months ago, it would be good. Right now with one 7800GTX beating it in some benchies, and SLi GTs and GTX raping it, this just doesn't cut it. Hopefully ATi has something amazing with the R520, otherwise they are heading back to the days of pre-R300.

Crossfire cards only use 5 watts of power!

again ... I appologize ... I forgot to hit the update button after I entered in the power consumption.

idle: 150W
load: 326W

Okay, I don't get this. I'm running a 24" widescreen monitor at 1920x1200@60HZ using single link DVI. The limit for single-link DVI at 60HZ is said to be 2.6 megapixels which is quite a bit higher than 1600x1200.

That's because all the video card vendors allow higher resolutions be reducing the video blanking perioed. This gives the card more time to send data, resulting in a higher available resolution.

One more correction by Leper Messiah, 1597 days ago
The last table on the last page is missing, there's just a [table] tag.
