R480 and SLI details emerge

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.

This speed comes at a price as ATI needs to use dual slot cooling. Oh boy, it criticised Nvidia for that. The tables have turned one more time.

The R480PRO will be a 12 pipeline version or R480XT card. It will clock at 520/1080 MHz. All cards will be announced in December as we said before.

We can add that ATI is considering either X850 or X900 as brand names but this depends on performance numbers. I would assume they will use X850, as these cards cannot be that much faster than current architecture. Still, you have to bear in mind that due to the 110 nanometre manufacture process, these cards should be much more available.

The site confirmed our previous article where we said that ATI's SLI marchitecture will be called ATI Multi Rendering AMR. Don't you think it's funny that its marchitecture shares the acronym of Audio Modem Riser slot? Our Italian friend confirms that ATI's current Radeon Xpress 200 AMD chipset codenamed RS480 and Intel based R400 already have support for AMR.
