In January of this year, at the Consumer Electronics Show in Las Vegas, NVIDIA and Dell jointly unveiled an ultra high-end gaming system equipped with a pair of specialized graphics adapters that were each powered by a pair of GeForce 7800 GTX GPUs and 1GB of memory. The final configuration consisted of two "cards", four GPUs, and a total of 2GB of graphics memory. NVIDIA dubbed the technology "Quad-SLI", and gave Dell an exclusive on the technology for a short period of time.
At the time NVIDIA didn't announce any plans to bring Quad-SLI to retail, but we all knew the day would eventually come. While that day is not today (technically), NVIDIA is laying the foundation for do-it-yourself Quad-SLI with the release of the new GeForce 7950 GX2. The GeForce 7950 GX2 is a refinement of the technologies employed in the first dual-GPU cards used in the original Quad-SLI design. The 7950 GX2 features newer GPUs and revised PCB designs that not only make the cards physically smaller, but more power efficient and ultimately more compatible with existing platforms. Though Quad-SLI may or may not be ready for prime time in the mainstream just yet, the GeForce 7950 GX2 is being targeted by NVIDIA as the fastest single graphics adapter on earth currently -- a single graphics adapter with dual GPUs.
