AMD gets ready to take on Intel's "Santa Rosa" with its next-generation "Trevally" mobile platform
AMD is currently providing partners with its next-generation
mobile reference design
Socket S1 Turion
features AMD’s upcoming
north bridge and new SB700 south-bridge.
In its mobile configuration, the
supports side port and MXM technologies for video upgrades. Notebook manufacturers are able to implement an external frame buffer for the integrated Radeon X700-derived graphics core using the available side port. Manufacturers are free to use 512-mbit DDR2 memory for the external frame buffer.
has an integrated Radeon X700-derived graphics core, it features eight PCIe lanes for an external graphics or greater video output capabilities. The eight PCIe lanes are routable to an MXM-slot for graphics card upgrades. Additionally, the eight PCIe lanes are SDVO compatible in case manufacturers want to implement TV, VGA and DVI outputs. Two PCIe x1 links are available for PCIe Ethernet and ExpressCard on
Connecting to the
IGP-north-bridge via a PCIe x4 interconnect is the new SB700 south-bridge. New features of the SB700 include more USB and SATA 3.0Gbps ports. SB700 increases the amount of supported USB 2.0 ports to 12 from the previous 10. Additionally, two USB 1.1 ports are supported for 14-supported USB ports.
AMD increased the total amount of SATA 3.0Gbps ports to six with the SB700; the
south-bridge only supports four SATA 3.0Gbps ports. While chipset manufacturers occasionally remove parallel ATA support completely with more SATA ports, AMD has opted to retain parallel ATA support. The
reference platform uses the ATA 66/100/133 interface for a flash memory module, similar to
It is unknown when AMD’s
platform will make its appearance, especially since

RE: Side Slot for memory

That side slot is for dedicated graphics memory for the x700-based GPU which is integrated into the RS690T chip. It's not for normal system memory. It's labelled "512Mbit" which I presume means that it only takes 64Mb of memory.
Until now, integrated graphics has used part of the normal system memory. This is slow because the GPU competes with the CPU for memory bandwidth, and slower still on AMD platforms where the memory controller is integrated into the CPU instead of the northbridge.

Yeah I knew all that, that's why I find it interesting. I don't want to pay for discrete graphics and lose battery life, but I'd love for my laptop's graphics to go obsolete (ie unusable for even Chicken Invaders 3 type stuff) maybe a year later than it otherwise would.
512Mb is 64MB, yes, but that's for each chip, a normal stick of memory has four or eight such chips, that's where I got 256MB from.
