AMD RD890: First choice for Phenom II overclocking?
The first AM3 motherboards for AMDs Phenom II will still be based on an updated RD790 Northbridge. But in Q2 2009 the RD890 chip is supposed to be released and combined with the also new SB800 Southbridge.
Besides additional USB and SATA connections the RD890 is said to offer a better power management, a faster connection between CPU and Northbridge and an improved hardware monitoring. Up to four graphics cards will be connected via PCI-E 2.0 x8 and alternatively two cards can run with the full x16 bandwidth.
In addition to those features Nordichardware expects better overclocking capabilities from the RD890 than from current AM2(+) motherboards. On those the Phenom II already reached more than 6 GHz when cooled with liquid nitrogen.
