PA Semi is rolling out a new multi core design that is low power. Here’s a block diagram of one of their designs.
They would like to use it just about everywhere except the desktop.

The 1361E is designed to excel across a broad range of applications. Its high floating-point and vector performance, comprehensive reliability features, integrated Gigabit Ethernet links, and virtualization support make it an ideal computing element within a supercomputer or multiprocessing blade. In networking applications, the 1361E advantage is underpinned by its advanced MAC features, offload engines for TCP/IP and cryptography, and availability of a high-speed CPU for control-plane processing, services, or content-inspection. Leading-edge storage applications benefit from the 1361E’s RAID and iSCSI acceleration hardware and its ample processing headroom for storage algorithms.
The followon, 1682M, is more of the same.
Here’s a table of their product offerings.
