The chaps over at TechReport take a look at the S3's MultiChrome dual-GPU technology.

But I'm somewhat disappointed that the total peak performance S3 can offer when it combines two of its best GPUs isn't terribly compelling. I had really hoped going to dual GPUs would allow S3 to offer some form of solution that might appeal to PC gamers and enthusiasts. Too much has happened since MultiChrome was first announced, and that's simply not the case. There's just no way this is a $200 graphics solution on the order of the GeForce 7600 GT. Buy one of those cards and you'll be far ahead of what a pair of Chrome S27 cards can offer. Even the Chrome S27's seriously low power consumption is sullied by the fact of its performance—really, performance per watt isn't much better than that of the GeForce 6600 GT, an older 110nm GPU. And given that major game titles like Guild Wars and Half-Life 2 were throwing up warning messages about undetected hardware, I am wobbly on the prospects for S3 sustaining the kind of developer relations and game profiling efforts necessary to make MultiChrome a success over the long term. I hope they do it, and they deserve credit for getting as far as they have, but buying a MultiChrome rig for gaming is a big risk.

In other news, PCStats has just posted a review of the S3 Chrome S27 PCI Express.
