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.
|8800 GTX||8800 GTS 640MB||8800 GTS 320MB||8600 GTS||8600 GT||8500 GT|

|GPU Process size||90 nm||90 nm||90 nm||80 nm||80 nm||80 nm|

|Memory Size||768 MB||640 MB||320 MB||256/512 MB||256 MB||256 MB|
|Core Clock||575 MHz||500 MHz||500 MHz||675 MHz||540 MHz||450 MHz|
|Memory Clock||900 MHz||800 MHz||800 MHz||1000 MHz||700 MHz||400 MHz|
|Shader Clock||1350 MHz||1200 MHz||1200 MHz||1450 MHz||1180 MHz||900 MHz|
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.
