We've confirmed the existence of yet another chipset that is about to arrive in Q1 2010 and it will support Arrandale 32nm CPU with 45nm GPU MCP.
The new chipset is targeted for small form factor machines, but it is not clear if this is meant for notebooks or small desktops, we believe its the later.
The „new“ chipset which looks like a derivation of QM57 chipset to us has support for 14 USB 2.0, PCIe 2.0 8X and 6 SATA 3Gb/s ports. The Arrandale integrated graphics will be there with PAVP 1.5 support, whatever that is.
The new chipset also supports Intel AMT 6.0, Brainwood memory support, Intel rapid storage technology and Intel AP-p. The launch date is Q1 2010 and the only mayor difference btwen QS57 and QM57 is that the later supports Clarksfield Quad core and the QS57 doesn’t.
