Expreview reports NVIDIA is working on a new PCB design for the GeForce GTX 260 that will be cheaper to manufacture. Compared to the P651 design, the new P654 will have 10 instead of 14 PCB layers, and it will lack the Volterra chip.
The first cards based on this design are expected in the third week of February, they are expected to cost about $10-15 less than the current GeForce GTX 260 cards.
According to the P897 design plan that NVIDIA sends its partners, it uses 4/6 phase NVVDD power solution ADP4100. It changes FBVDDQ power solution from 2-phase to single phase. And the MOSFET package has been changed from LFPAK to DPAK to save cost. Another noticeable change is the PCB layer decreases from 10 to 8. The length of PCB keeps unchanged, while the height of it is reduced by 1.5cm. In order to cut cost further, they will change DVI connector, crystal and probably change BIOS Rom from 1M to 512K.
