the Calxeda's ECX-1000 server node is revolutionary technology. When we ran 16 VMs (instead of 24), the dual low power Xeon was capable of achieving the same performance per VM as the Calxeda server nodes. That this 24 node system could offer 50% more throughput at 10% lower power than one of the best Xeon machines available was honestly surprising to us. 8W at the wall per server node—exactly what Calxeda claimed—is nothing short of remarkable, because it means that the 48 server node machine, which is also available, is even more efficient.
It boils down to a bull vs a flock of chickens. The flock of chicken cannot pull a cart, but can pick a lot of seeds on the ground a hell lot faster than the bull can. But the flock of chicken cannot pull the cart, only the bull can.
Need to compare ARM to Atom, chicken versus turkey.
Not remotely good enough. It takes 24 nodes and 96 A9 cores to get in the same ballpark as the simplest 2-way Xeon server with a pair of octo-core Romleys, i.e. 16 Xeon cores. Romley was meant for 4-way servers, a 4-way Romley (32 cores) would beat this Boston on performance, performance/watt and price. Sorry it's a big fail and the buying market will agree.
