Nvidia to launch GeForce GTX 880 in September

The cat is out of the bag as multiple sources now have reported that Nvidia is sending out invites to press to attend a product briefing in San Francisco. It is expected that Nvidia here will launch the new Maxwell based GeForce GTX 880 and perhaps 870 as well. A week or two ago we already noticed some gamescom activity where Nvidia might tease the product. As it stands, the launchs in September might be a paper launch with product availability in the weeks to follow.

GeForce GTX 880 will be based on the GM204-GB3-256 GPU, it is one of the best sectrets to date as nobody really knows the shader processor count to date. All specs and speculated, but GM204 is expected to be a 28 nm process product, with later in the pipeline a 20 nm version.

The latest rumors indicate that the GTX 880 features 7.9 billion transistors with a whopping 3,200 CUDA cores. The product would get 200 TMUs and 32 ROPs offering a 5.7 TFLOP/s single-precision floating-point throughput. Memory you are looking at a 256-bit wide GDDR5 memory interface with 4 GB being the standard memory amount. With a memory clock-speed of 7.4 Ghz that would get the product a 238 GB/s memory bandwidth.

Now obviously we can not validate the score or anything, but this might be too much of a coincidence to suddenly appear on the web. And then there's this from the NVIDIA UK Facebook.
