TweakTown heard AMD is planning to include support for SATA 6Gbps in its SB800 southbrige, this chip is expected to debut in Q1 2010. While SATA III support is a plus, it's still disappointing that the SB800 won't support USB 3.0.
If this is indeed the case, it would mean littler chipper (AMD) could even leapfrog Intel in Southbridge technology, something which we are currently taking with a pile of believe-it-when-we-see-it salt, as AMD have something of a track record of being a generation behind Chipzilla on SB tech.
Another industry source told us AMD would definitely have SATA 3 native on SB800 but that USB3 would likely not be and would require a third party chip. Word from motherboard makers is that those who want to add SATA3 to their Intel mainboards will have to use a third party chip like the Marvell offering GIGABYTE was showing off at Computex a couple of weeks ago on its P55 products.
