A few more drips of gossip concerning Nvidia's forthcoming GF104 GPU have just dribbled out of the rumour tap, including a photo of the elusive chip.
The snapshot comes courtesy of a chap who calls himself woaiamd123 on the Zol forums (opens in new tab) in China. Expreview (opens in new tab) grabbed it and revealed it to the world, showing that it's quite a different piece of silicon from the GF100. Unlike the square GF100 package found on Nvidia's current GeForce GTX 400-series cards, it looks as though the GF104 comes in a rectangular package.
This isn't the first time the shape of the GF104 package has been revealed. Last month, Chinese tech site eNet posted a supposed die-shot of the GF104, along with a PCB diagram for the graphics card. The story has since been taken down, but you can still access an archived version (opens in new tab) (Google Translation).
Although the photo was regarded as a fake (opens in new tab), made simply by squashing a GF100 die-shot, it looks as though eNet might have had the right idea with regards to the shape. In fact, the site probably mocked up the photo to show what the die could potentially look like.
Elsewhere, more potential details have emerged about the specs of the GF104 GPU. Earlier rumours (opens in new tab) suggested Nvidia's GeForce GTX 460 chip would come with 336 stream processors, but this number doesn't divide neatly by 32, prompting us to speculate that Nvidia's new chip bundled together stream processors in groups of 16, rather than 32.
However, the guys at Fudzilla (opens in new tab) claim to have unearthed some more information that makes sense of this. According to the site, the GF104 has a total count of 384 stream processors, divided into 16 blocks of 24 (rather than 32) with a 256-bit memory interface.
The site reckons the GeForce GTX 460 doesn't make full use of the chip's potential, and instead just features 14 of the blocks of stream processors, along with a 192-bit memory interface. As such, it's quite possible Nvidia could release another high-sped GF104-based card in the future.
The GeForce GTX 460 is expected to be officially released by Nvidia next month, with 336 stream processors clocked at 1,350MHz, and 768MB of GDDR5 memory clocked at 1,800MHz (3,600MHz effective).
