Tweaktown writes the latest GeForce GTX 800 series rumors point to a October or November launch date. Unfortunately, we still known very little about NVIDIA's next high-end card but it's believed that the GTX 880 will be based on a 28nm GM204 GPU with 8GB GDDR5 memory and a 375W TDP.
We already know that the upcoming GTX 800 series will be a powerhouse series of video cards, with the two GPUs being positioned for the high-end market. The GTX 870 and GTX 880 will replace the current GTX 780 and GTX 780 Ti video cards, with the new GM204-based hardware. The last time we heard about the GTX 880, we heard that it sported 8GB of RAM and a 375W TDP.
The GeForce GTX 800 series should arrive on the 28nm process, and not the 20nm process like some thought it would. The biggest tease is that NVIDIA is rumored to launch its GeForce GTX 990 early next year, something that would truly break some speed records as it will be based on the 16nm process, skipping the 20nm process entirely.
