It featured P654 reference design, which cost less than earlier P651. The number of PCB layers reduced from 14 to 10, and it has abandoned the expensive Volterra chip to cut cost. Quite soon, the third-generation GTX260 design plan with codename of “P897/D10U-20″ will be also surfaced. <a href="http://en.expreview.com/2008/12/27/the-first-review-of-55nm-geforce-gtx260.html" target="_blank"></a><a href="http://en.expreview.com/2008/12/27/the-first-review-of-55nm-geforce-gtx260.html" target="_blank"></a><img src="http://en.expreview.com/img/2009/02/07/P897.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> The schedule drawing of P897 PCB designAccording 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. <img src="http://en.expreview.com/img/2009/02/07/GTX2601.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> But for the GT200 and NVIO2 chip, you might mistake GeForce GTX260 of P897 PCB design for GeForce 9800GTX+ (as they look so similar). Compared with P654 design, P897 GeForce GTX260 is expected to save cost of $10 to $15, which will undoubtedly improve its competitiveness. According to our source, this product will be available in the third week of this month. We also manage to get some pictures of new GTX260 from a Chinese manufactuer Colorful. Coming from their iGame Series, this GeForce GTX260 card is designed based on P897 PCB design. They have just changed the TV-out connector to HDMI and added a set of overclocking jumper.<img src="http://en.expreview.com/img/2009/02/07/GTX2602.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> The MOSFET is packaged with lower cost DPAK. Note that these are just designs from colorful. <img src="http://en.expreview.com/img/2009/02/07/GTX260cooler1.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://en.expreview.com/img/2009/02/07/GTX260cooler2.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> <img src="http://en.expreview.com/img/2009/02/07/GTX260cooler3.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> </blockquote>
