GF104 graphics chip may be more than meets the eye

On Monday, we came across leaked specifications for a GeForce GTX 460 graphics card based on Nvidia's upcoming GF104 chip. Fudzilla now reports that the card won't use the GF104 to its full potential, instead leaving some parts of the silicon disabled.

According to Fudzilla, the GF104 will have 384 stream processors set up in 16 clusters, and it will also feature a 256-bit memory interface. The GeForce GTX 460, by contrast, is rumored to have only 336 SPs and a 192-bit path to memory.

Assuming that information checks out, Nvidia could have room to introduce a more powerful GF104-based product priced in GF100 territory. (Expreview, which broke the GTX 460 specs, quotes a $230 launch price for that card.) Fudzilla draws a parallel to the GeForce 8800 GT, which had only 112 of the G92 GPU's 128 stream processors enabled. Nvidia went on to release a number of faster G92-based cards, including the GeForce 9800 GTX and, most recently, the GeForce GTS 250 1GB.

Another Fudzilla report notes that a cheaper GF104-based card will also accompany the GeForce GTX 460. The site mentions only a name—GeForce GTS 455—adding that Nvidia has yet to finalize specifications. If the GTX 460 does launch at $230, though, perhaps the GTS 455 will sell for less than $200. Then again, Nvidia hasn't even announced the GF104 yet, so there's a chance none of this information is even remotely true. Ah, the beauty of Internet rumors.
