FUD Zilla heard AMD's upcoming ATI RD890 chipset will have a TDP of 18W, which is pretty high especially considering that this chipset doesn't have integrated graphics. Motherboards based on the RD890 are expected in Q4 2009.
The best overclocker AM3, DDR3 chipset that should launch in Q4 2009 codenamed RD890 has a TDP of 18W. This is definitely not a small number as this chipset doesn’t have an IGP graphics core and simply takes care of PCIe 2.0 with Crossfire. AMD 790FX chipset for example has 13W TDP.
The new thing to come with RD890 is support for 6x1X Gen 2 and 1x4X PCIe port. The RD890 chip will use 29mm FCBGA package and it will interconnect with SB850 or cheaper SB810 Southbridge.
