The guys from FUD Zilla claim the Hybrid SLI technology from NVIDIA will at first only be available for the AMD platform.
This technology works a bit like SLI but uses the IGP to augment the performance of a discrete graphics card. This should be useful on low-end systems but early results indicate people with high-end rigs may also get a couple percents of extra performance with this technology.
Integrated IGP graphics will boost the graphics card's performance and it will be faster, but only if you use AMD 750a and 780a. This architecture won't work on Intel Nvidia 7x0i integrated chipset, at least not at launch time. It has to be a driver issue and it is interesting that we wrote about this back in August and got it right, here.
The Intel solution will come a bit later, probably next year as there is no much time left in this exciting 2007. We remember that back at the summer analyst conference call Nvidia said publically that the company is traditionally faster and better with AMD’s chipsets and this is the reason why Hybrid SLI launches at AMD platform first.
