Nvidia to Release Single PCB GTX295
Though the GeForce GTX275 and Radeon HD 4890 seem to getting a good deal of attention of late, it seems that a bigger story may be looming at the top end of the graphics card food chain. http://en.expreview.com/2009/03/25/nvidias-scheme-of-single-pcb-reference-gtx295-outlined.html is reporting that NVIDIA is working on a new GTX295 reference design card featuring single PCB. Similar to the ATI Radeon 4870 X2, the new GTX295 will drop two GPUs onto one PCB. NVIDIA has not been entirely successful in going this route in the past, so it will be interesting to see how this round shakes out.
The current GTX295 design features dual-PCB design codenamed P656 with one GPU on each, sandwiched together in traditional NVIDIA fashion. The new GTX295 will adopt a single PCB design known as P658, which means NVIDIA need to pack two G200 chips onto one PCB board. This obviously means that the power management components need to be redesigned and consolidated, which should theoretically significant reduce the production costs.
The clock speeds and performance of the new GTX295 will remain unchanged with this release, and 6+8-pin power connectors will be used, similar to the Radeon 4870 X2.
NVIDIA is said to be finalizing the engineering sample of new GTX 295 within April, but it won?t be officially launched until May.
