Introduction



Today NVIDIA announced their new GeForce 8800 GT Series using the all-new G92 GPU. The GPU is made on a 65nm process, based on the G80 of the 8800 GTS/GTX/Ultra. The card is set to replace the 8800 GTS 320 MB which will be phased out soon (the 640 MB version will stay for now). A 65nm process allowed NVIDIA to manufacture the chip cheaper, with less heat output and to add additional features. For example the display output logic, which was on a separate chip on the 8800 GTX has been integrated into the GPU core. Also the new HD video decode acceleration features have been ported over from the G86, so you can now benefit from full VC-1 and H.264 decode acceleration. HDMI + Audio is not part of the NVIDIA reference design, but this can be added by 3rd party vendors easily. Unlike the 8500/8600 Series, the GPU uses a 256-bit memory bus which doubles the available memory bandwidth for applications. The number of shaders has been set to 112 compared to 96 on the 8800 GTS. This should increase performance in modern games which use a lot of shaders.

Zotac as one of NVIDIA's premier vendors took the NVIDIA GeForce 8800 GT reference design and increased the clock speed by 60 MHz - for no extra price. Actually all Zotac 8800 GT cards will have those higher clocks which will give a nice performance advantage over the competition. An "AMP! Edition" card will also be available which uses even higher clocks of 700 MHz core and 1000 MHz memory for a price premium of $10.
