The annual IT and electronics fest that is Computex may have just started in Taipei but the graphics scene has already seen the first summer salvo – NVIDIA's 'SLI in a basket' GeForce 7950 GX2. Although NVIDIA had previously debuted Quad SLI setups on quite a few occasions, these systems were limited to high-end rigs from system builders like Dell and standalone cards were unavailable.
That all changed a few days ago, when NVIDIA officially took the wraps off its GeForce 7950 GX2. Basically, this dual GPU, dual PCB hybrid is a SLI setup all by itself, thanks to an integrated SLI bridge chip between the two PCB. There's also an onboard PCI Express switch that manages the combined PCI Express bandwidth between the two GPUs. This additional component also means that though all PCI Express capable motherboards (not just SLI boards) can support the GeForce 7950 GX2, but a BIOS update is required before the switch can work properly.
Although Quad SLI has been disabled for now (probably due to business rather than strictly technical reasons), the possibility and hardware remains. Meanwhile, two G71 cores on a single sandwich of a card should provide performance the rough equivalent of a GeForce 7900 GT SLI setup or better, especially since the core and memory clocks are closer to the GeForce 7900 GT than the high frequencies of the flagship GeForce 7900 GTX.
That's in essence a summary of the exciting developments behind the NVIDIA GeForce 7950 GX2. For more about this card and Quad SLI, you can refer to our related links below. Today, we have an actual retail ready GeForce 7950 GX2 unit from one of the largest vendors around, MSI. These cards and more, are likely populating a retail shop near you by now. So now, let's take a look at this Siamese twinned graphics card:
