The XLP980 and the CaviumCNxx are similar in so many ways but yet different. They both seem to have a slew of accelerators specific to the networking segment, both use MIPs based CPUs and are on 28nm. But the CPU implementations are different. Netlogic's is an out-of-order multi-thread while Cavium is an in-order single-thread. I wonder which is better suited for the target application.
Interestingly the Intel processors are also out-of-order multi-threaded so it might appear that the XLP can better compete with Intel.
Intel, Comcast, Cisco just announced the XFINITY Wireless Gateway. It uses Intel's Puma 6 silicon. The Wireless Gateway from XFINITY Internet is capable of up to 16 bonded downstream channels supporting speeds up to 640 Mbps.
The Puma 6 is the first DOCSIS silicon to reach up 1 Gbps downstream by bonding up to 24 DOCSIS channels and up to 240 Mbps upstream by bonding up to 8 DOCSIS return channels
