The GeForce GTX 295 has officially been out for four months now, and it's still fairly hard to come by. However, Expreview has posted images that suggest Nvidia will soon introduce a new version of the card with a simpler design.
This new version will shed the dual-circuit-board layout for a single-PCB approach, but it will supposedly retain the same specifications. That means dual 55nm GT200 graphics processors clocked at 576MHz, 1792MB of total GDDR3 memory, a 289W thermal envelope, and both 6-pin and 8-pin power connectors. Even the actual PCB length should remain unchanged at 267 mm (10.5"), Expreview says.
Nevertheless, both GT200b chips will apparently reside on the same side of a single PCB. Individual aluminum heatsinks with copper heat pipes will cover each GPU, and an 88.5-mm fan will sit in the middle, blowing hot air out through the back of the system. The previous design had the cooling mechanism sandwiched between both PCBs.
If Expreview's images are genuine (and they certainly look to be), this revamped GeForce GTX 295 will represent an interesting departure for Nvidia. The company stuck with dual-PCB designs for its previous dual-GPU offerings, the GeForce 7950 GX2 and GeForce 9800 GX2. AMD, by contrast, has used single PCBs for both the Radeon HD 3870 X2 and the new 4870 X2. Perhaps the single-PCB approach will allow Nvidia to cut costs and increase availability.
