The Geforce 8600 Ultra supports 64 Stream processors and works at 500 MHz core and 1400 MHz memory. It has 256 Mbit memory controller and 256 or 512 MBs of memory. This depends of the Vendor specific designs. Its estimated retail price is suppose to settle around $179 but we recon it will sell for 20 more.
Geforce 8600 GT - again a mainstream chip - will end up with 48 stream processors and 350 MHz core clock. The memory will work at 1200 MHz and the card will have 256 bit memory controller and 128MB or 256 MB of ram. It should sell for $149 and this is a good price for DirectX10 part.
This card will replace 7900GTs and GS and 7600 cards. These cards are scheduled for February announcement if not March but the chips are already sampled.
