Kitguru spreads news that NVIDIA may release up to three GeForce GTX 800 graphics cards in October.
These cards will be made on NVIDIA's GM204, a secon-generation Maxwell chip still manufactured on a 28nm process. It's unknown what performance level will be offered by these cards.
Hermitage Akihabara web-site reports that Nvidia plans to introduce high-end GeForce GTX 870 and GeForce GTX 880 graphics cards based on the GM204 graphics processor in early October. In late October the company intends to release GeForce GTX 860 graphics adapter aiming mid-range market segment. It is likely that the solution will also be based on the GM204 graphics processing unit.
Keeping in mind that the GeForce GTX 860 will unlikely cost substantially more than $300/£200, it is logical to assume that the GM204 chip is not too expensive to manufacture.
