Last week we already mentioned that it is very plausible to see Nvidia release the GeForce GTX 880 and or 870 next month. Over at the ChinaJoy Game Developers Conference a representative of Gigabyte made a bit of a boo-boo and actually confirmed that to be correct. In fact he even mentioned the development of a GeForce GTX 880 G1.Gamer

He stated that gigabyte is working on a custom-design card based on the new chip, named GeForce GTX 880 G1.Gamer.

The new card will be designed with a heavy duty cooler capable of handling thermal loads as high as 650W (if you look at our Titan Black review - that is likely to be the cooler). 

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.
