It looks like the new P55 and P57 will not ship with SATA 3 support.
Despite the fact that AMD is planning one with SATA 3 support for Q1 2010, Intel will not make that feature available on tits next two chipsets.
SATA 3 can support up to 6Gbps (750MBps) while the older SATA 2 only supports up to 3Gbps (375MBps).
Intel is sure to have SATA 3 support soon but it looks like AMD will beat them to the punch.

it turns out that its new 5th generation mainstream chipsets won't feature support for SATA 6Gb/s. Both P55, that comes in Q3 2009, and P57 that comes in Q1 2010 and has better support for 32nm CPU with IGP Clarksdale, won't support SATA 3.
This comes as quite a surprise, as AMD prepares its SB820 Southbridge that should have SATA 3 support and this Southbridge should launch in early 2010. Since both P55 and P57 are single chip chipsets Intel will have to release a new chipset to get SATA 3 support.
