The Geforce 8950 GX2 is a dual-chip card based on a new 80 nanometre G80 chip, probably codenamed something else. Both GX2 GPUs are clocked at 550MHz and the difference is GDDR4. The card comes with 2x512MB of 256-bit GDDR4 memory clocked at 2000MHz. The card has 96 Shaders, per chip. It will be priced at $600.
The second in Nvidia's spring line-up is the Geforce 8900 GTX clocked at 700MHz GPU and 2200MHz memory. The chip still has a 384-bit memory interface and comes with 768MB of memory. The card uses a new 80 nanometre chip and has 128 Shaders. Compared to the Radeon X2800XTX it will end up shorter on clock and memory interface.
The Geforce 8900 GTX is priced at $550.
Meanwhile, the Geforce 8900 GTS is a new card clocked at 600MHz GPU with 2000MHz GDDR4 memory. It supports the 320-bit memory controller and comes with 640Mb of memory. This card should cost $500 and it is using the 80 nanometre chip. This card will still have 128 Shader units.

---------------------
Nvidia has two more 80 nanometre cards. The Geforce 8900GT with 600MHz core and with a 256-bit memory interface comes with 512MB of 1800MHz GDDR3 memory. It has 96 Shaders and is built on a 80 nanometre process and will cost $400.
The 8900 GS will be the cheapest G80-based card. The 80 nanometre based beast is clocked at 550MHz core and 1600MHZ memory. The card has the 256-bit memory controller and comes with 256 or 512MB of GDDR3 memory. It also has 96 Shaders. The 256MB version will cost $200 while 512MB incarnation will end up at around the $250 price mark.
