Now that's interesting. Why on earth aren't they leading with it?

I can understand these kinds of faux benchmarks and whitepapers to convince pointy haired bosses to switch between mature, mainstream technologies.

But the early adopters of fringe technology like this are going to be companies with specific needs, and those making the decisions are going to be highly technical. Not to generalize, but they (me included) love details and possibilities, and abhor marketing puffery.

Calxeda should be sketching out novel ways to use the interconnect bandwidth to solve hard problems, with power efficiency x86 can't touch. Not running ab against an ARM core and misinterpreting the results. Sheesh.



well, there is a promising HP project Moonshot, which was going to build on this platform, but it seems that they recently decided to switch to Intel solution.. http://www.engadget.com/2012/06/20/project-moonshot-take-two...


Calxeda five XAUI (50 Gbps) to a 4 core 1.1GHz 5W. 200ns per hop.

A ToR switch will slow you down to 2000-3500ns.

Tilera TilePro64, 64 core 866MHz 22W, 1.7Tbps core-to-core, 46ns L1/L2 miss found in adjacent core, four XAUI (40 Gbps).

When compared to Tilera, Calxeda has a high bandwith per compute ratio. But 200ns core-to-core is not as fast as 46ns.

Tilera also has higher core/watt ratio.
