New Multi-GPU Technology With No Strings Attached
Vigile writes "Multi-GPU technology from both NVIDIA and ATI has long been dependent on many factors including specific motherboard chipsets and forcing gamers to buy similar GPUs within a single generation. A new company called Lucid Logix is showing off a product that could potentially allow vastly different GPUs to work in tandem while still promising near-linear scaling on up to four chips. The HYDRA Engine is dedicated silicon that dissects DirectX and OpenGL calls and modifies them directly to be distributed among the available graphics processors. That means the aging GeForce 6800 GT card in your closet might be useful once again and the future of one motherboard supporting both AMD and NVIDIA multi-GPU configurations could be very near."
If there's no strings, how are they connected?
No, but I did throw granola at a deaf person once
Put it this way, if it was a disparate CPU multiprocessor board, and the summary said "Perhaps my p4 will now be useful again", everyone would be laughing.
A 6800GT would be an insignificant fraction of a new card, and would still be under 10% of a $50 no-name 8 series (while still sucking down the same wattage).
Considering that matched SLI is usually a waste of money - you can buy that second card in a years time when your current one shows age, and end up with a better card than twice your previous one (and supporting Shader Model Super Titrenderer 7), which your old card can't do), I'm not sure how this is going to be of much benefit.
If it was useful to jam a bunch of cheap chips in then the card manufacturers would be doing it on more of a scale than the "desk heater dual" cards (which are basically SLI-in-a-box) at double price. You can't get a card with 4x 6800 chips at $5 each, because they'd be destroyed by the $10 8 series chip on a $50 card.
