HKEPC reports that the next generation of mainstream NVIDIA G92 chip will be launch at 12th November, to replace the current GeForce 8800GTS series. The G92 GPU is to set to compete with AMD RV670 which expected to come out on December. The other GPU, the G98 is answer to AMD's RV620 GPU which target the lower end market. The launch date of G98 is not confirmed yet.

G92 GPU is using 65nm process and manufactured by TSMC, technical specification is similar to 8800GTS with 256 bit memory controller, supporting the new PCI-Express 2.0. Texture fill rate goes from 25GT/s to 50GT/s. The GPU will fully support HDMI and PURE VIDEO GEN 3, using DISPLAY PORT output but the G92 GPU will still name under GeForce 8 family.

UPDATE: Looks like the G92 may actually replace the GTX, not the GTS. It has a 384-bit memory bus!

This baby sports some serious shading power, but more important is the fact that the memory installed on board is now GDDR4. 768MB of GDDR4, to be more precise. The amount of memory discards rumours of 256-bit bus, since it is obvious that Nvidia will keep 384-bit memory controller for the high-end series of products. We would welcome this memory controller in mainstream arena, though.
