R480 and SLI details emerge@ 2004/11/10
R480XT Platinum Edition is likely to be clocked at 540MHz while it memory should rock at 1180MHz. This is 20MHz core and 60MHz memory speed upgrades from fastest of AGP X800 XT Platinum Edition card. Just for the record, R480 cards are PCI Express only.
Its memory will work at an impressive 590MHz. The second card, the R480XT should be clocked at 520MHz while its memory will work at 1080MHz. It will be interesting to position this card against X800XT PCIe express as this card is clocked at 500/1000MHz or 20MHz core and 80MHz memory slower. Both X800XT PE and R480XT are 16 pipes cards with 256MB of memory and will use a 256 bit interface.
