Nvidia's grip on its secret plans appears to have slackened again, as more details have emerged about a graphics card based on the company's forthcoming GF106 chip.
Just a couple of days after rumours appeared about the GeForce GTX 450's memory interface, a couple of PCB diagrams have now turned up on the scene.
The plans first appeared on the Chinese-language PCInLife forums yesterday, and were then picked up by Expreview. According to the sites, the pictures detail a graphics card based on Nvidia's GF106 chip, although it's not known whether it's specifically a GeForce GTS 450 card yet.
We've performed a few rough calculations based on the diagrams, which show the card has a 210mm PCB (the same length as GeForce GTX 460 cards), while the chip comes in a (roughly) 34 x 34mm square package. If the diagrams are legitimate, then it looks as though the GF106 is quite a different chip from the GF104, which has a peculiar rectangular shape.
The charts also show mounting spaces for six memory chips, meaning this card could come with 768MB of memory (6x 128MB), as well as a pair of DVI outputs and an SLI connector on the top.
Interestingly, however, there are only solder points for one six-pin PCI-E power connector on the edge of the card, meaning its power consumption must be well under 150W. Meanwhile, it looks as though the card will feature a similar cooler to the GeForce GTX 460, with a single central fan cooling both the chip and the memory.
Previous rumours have stated that the GeForce GTS 450 will feature 1GB of GDDR5 memory with a 128-bit interface, which doesn't marry up with these diagrams. However, the GeForce GTX 460 comes in both 1GB and 768MB flavours, and Nvidia may have similar plans for the GeForce GTS 450.
If previous rumours are to be believed, then the GeForce GTS 450 is currently lined up to be released in August this year.
