Here's the press release. And here's some details.
Let me see if I've got this down...
AMD 8151:
Basically, this replaces the NorthBridge. However, since ClawHammer is going to integrate most of standard NB's functions (like the memory controller), it's not *really* a NorthBridge. Basically, the 8151 provides a HyperTransport AGP3.0 graphics tunnel.
AMD 8111:
Overall, this replaces the SouthBridge. It also utilizes HyperTransport technology as an I/O hub, and is comprised of other features like integrating audio, storage, I/O expansion, security, and connectivity.
AMD 8131:
This device has two high-speed and independent PCI-X bus bridges. It seems like this will be aimed at server/workstation systems for SledgeHammer.
So ClawHammer will likely utilize just the AMD 8151 and 8111 bridges, with SledgeHammer adding the 8131 bridge to it's power.
What I'm wondering is exactly what does the 8131 function as in today's terms? What device currently present on motherboards does the 8131 replace (if replace at all?)? Having 2 separate PCI-X bridges means what?
What does this mean for future chipset and motherboard layout designs? I know, it's pretty early, but what information can we take from these details?
