Introduction


Today NVIDIA announced their new mainstream GeForce 8 Series based on the new 80nm G84 and G86 GPUs.

The new line-up of GPUs actually conists of five different offerings. The 8600 GTS is the most powerful mainstream GPU, followed by the 8600 GT. There is also an 8500 GT, which will not feature a seperate SLI connector, but will be capable of the dual graphic card standard from NVIDIA using PCI-E transfers. The company will also be offering a GeForce 8300 GS and 8400 GS to OEMs only to integrate into systems.

Looking at these specs, it seems like there is a very large difference between the 8800 based cards and the 8600 series. While the new mainstream cards only have 32 shaders and only 128 bit bandwith, they are clocked quite high. The high performance on single slot cooling is possible due to the 80nm prodcess and greatly reduced transistor count.
