Lucid's Multi-GPU Wonder: More Information on the Hydra 100by Derek Wilson on August 22, 2008 4:00 PM EST

So, lots of people were asking really good questions about Lucid and their Hydra engine after we posted the initial story on it. We had the opportunity to sit down with them and ask some of those and other questions. And they had quite a lot of really interesting things to say.
From a mile high and the promise of hardware not this year but next, it is tough to really get a good understanding of exactly what's going on and what the implications of this hardware could be if they can deliver on what they say they can. We'll do our best to explain what we know and also what the pitfalls could be.
First, let's address the issue of the box we showed off in the previous coverage. No it will not need an external device. Lucid has designed this to be solution that can be dropped onto a motherboard or a graphics card so integration and user experience should be seamless.
This would be even more transparent than SLI and CrossFire because not even an internal bridge would be needed. Just plug any two cards from the same vendor (and i think they also need to use the same driver version though this is less than clear) and performance will scale linearly with the capabilities of each card.
They did mention the fact that they can implement a solution in an external box for notebooks. For those who need something portable but want high end graphics at home, they could just attach the graphics cards linked with a Hyrda 100 (via PCIe over cables) to the notebook. Not ideal, but it still offers some advantages over high end internal cards (especially in the area of heat) that you might not need when you're on the road.
Sound too good to be true? Yes. Did we see it working? Sure. Do we have performance numbers? Not yet. So there's the rub for us. We really want to put this thing through its paces before we sign off on it. Running on both UT3 and Crysis (DX9 only for now -- DX10 before the product ships though) is cool, but claiming application agnostic linear scaling over an arbitrary number of GPUs of differing capability is a tough pill to swallow without independent confirmation.
We asked them for hardware, and we really hope they'll get us some sooner rather than later. They seemed interested in letting us test it as well. Even if we can't publish numbers on it, it would go a long way for us being more excited about the product if we could run our own benchmarks on it just to see for ourselves.
