Expreview claims they have the first photo of a 55nm GT200 GPU on a GeForce GTX 260 graphics card, the site says these new cards will hit retail shelves in January. Expreview also claims more G200b cards, including GeForce GTX 280 and a dual-GPU GeForce GTX 260 GX2 will be launched in January 2009 as well.
According to the image we have on hand, the mark of GT200b on GeForce GTX260 graphic card will change from 65nm "G200-103-A2" to be "G200-103-B2". The "B" means latest 55nm processing technology, and its production cycle happened during the 33rd week of this year (August 11th to 17th), only 5 weeks after G200-103-A2 which was manufactured in the 28th week. Therefore, obviously NVIDIA had prepared for a long time.
The first of new GTX260 graphic cards will hit the market in January next year. The number of its stream processors will maintain as 216, and its memory frequency is unchanged as well. The reference and non-reference versions cards will be on sale at the same time. Thanks to application of new processor and the circuit designed by manufacturers themselves, the price will hopefully keep declining. The GTX260 card is already available at $264 at the lowest right now.
Here's a look at the photo of the 55nm GT200 GPU. I'm not convinced it's real though, the "G200-103-B2" text stands out too much and the perspective is slightly different than the other text on the heatspreader. It certainly looks more like a photoshop than the real thing.
