ad RAM: the platform (if it is real) is little bit more interesting - they have cards with 16GB RAM per four 4-core CPUs (SoCs) - these cards are to be used together in amount of tens, connected with high speed switched fabric in the host board.. so it's something like server cluster on board design.. http://www.calxeda.com/technology/products/energycards/quadn...
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.
I think you misread that page. I think they mean that each SoC has one memory slot, which supports max 4GB RAM. So that 16 gigs is total amount for all the four CPUs. This still strongly points towards a 32-bit design.
