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

20 out-of-order cores, multi-threading and multi-chip coherency. That is certainly a beast. Rick, any idea what the die size and power consumptions are.

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.

Great observations and questions Mike. I have no doe size, cost or power numbers from Broadcom. Anyone out there have this data?
