Nvidia Unveils Dual-GPU Card – GeForce 7950 GX2

Nvidia, the graphic card manufacturer, has launched its new dual-G71-GPUs based graphic card package, the GeForce 7950 GX2, today.

nvidia-gforce-7950-gx2The Nvidia 7950 GX2 has two mobile GPUs (graphic processing units) which run in parallel across an internal connector, offering what Nvidia claims is the best single card performance on any graphic card package in the world.

The Nvidia 7950 GX2 is still two cards mounted together but Nvidia has had to do some tweaking in order for both to work together within this form factor.

The two chips are on two separate PCBs and are cooled by two separate coolers, much as with the 7900 GX2 Quad-SLI cards.

Each board has 512MB of memory, making the combined graphic package of 1GB. The Nvidia 7950 GX2 card supports Nvidia’s LinkBoost technology in the latest nForce 500 series motherboards, giving a guaranteed overclock of the PCI and HyperTransport bus for faster and more robust performance.

The presence of two seperate GPUs (graphic processing units) manages to boost total memory bandwidth from the 7900’s 51.2 GB/sec to a formidable 78.6 GB/sec as compared to the standard cards, such as from Club3D, which are clocked at 500MHz core and 1200MHz memory. XFX, however, has two variants – one at 520/1300 and one at an outrageous 570/1550.

Nvidia claims the dual-GPU 7950 GX2 graphic card actually delivers 48 pixel pipes, 16 vertex shaders, 76.8 GB per second of memory bandwidth and 24 billion texels per second of fill rate in a single card, complemented by a pair of DVI connections. The two GPUs are apired with a full gigabyte of DDR-2 memory as a frame buffer, allowing monstrous resolutions up to 2560 X 1600.

The idea of packing two graphics processors (GPUs) is not new. Gigabyte, Nvidia’s competitor in graphic card accessories, unveiled its dual GPU based design around 6600 GT graphic processors in February 2005, followed by a version the same which used regular 6600 graphic processors which in turn was followed by 6800 GT variant of processor that arrived in May 2005.

Nvidia 7950 GX2 card is also being marketed as “HDCP-capable,” essentially requiring installation of other components that use HDCP technology.

The cards are available from various online vendors at suggested price ranging from about $650 to $750.
