We looked a bit deeper in Intel’s plans for Clarkdale and
Lynnfield CPUs and 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.
The SATA 3 specification will offer up to 750MB/s transfers
while SATA 2 offers only 375MB/s. Some SSD drives
will definitely need SATA 3 bandwidth, especially when raided, and we are sure
that Intel will get a chipset with SATA 3 support, but obviously not in Q1 2010.
Intel still not going there
