I just received Nvidia’s Jetson dev card (Tegra 4). Haven’t had a chance to benchmark them but I would bet money that they are faster than the Tegra 3 based cards. The biggest weakness of 32 bit ARM CPUs is that their memory system tends to be slower (with few exceptions namely SOCs designed for server deployment) which means their I/O system tends to be slower. You didn’t mention cost? :) For general purpose server use, I would suggest one of the x86 boxen with a laptop chipset. They can come pretty close to 10W. I’ve seen a ultrabook that drew less than 10W under normal use. /sc
