In the second half of 2009 AMD plans to upgrade its Dragon platform to a new one, called Leo. Leo will have a 45nm Deneb-based core as the base, next generation graphics, most likely the upcoming 40nm Radeon refresh and an RD890 motherboard.
The RD890 is AMD’s highest-end chipset that will go well together with SB800 Southbridge. This chipset supports Hypertransport 3.0 and it should improve overclocking scores. It supports second generation PCIe and two and four way Crossfire with improved P2P.
The SB800, Southbridge part of the chipset, will have support for SATA 6 Gb/s, Radeon 0, 1, 5 and 10 and something called advanced clock calibration. This chipset has support for both AM2+ DDR2-based Phenom II’s as well as AM3, DDR3-based Phenom II, Deneb generation CPUs, but this support will depend on the motherboard design.
RS880D is the integrated version of the same chipset.
