TI OMAP4660 ARM Cortex-A9 PandaBoard ES Benchmarks
The OpenSSL performance on the PandaBoard ES was at nearly the same speed as the tested Atom processors from Intel. Surprisingly, the OLPC XO-1.75 with its single-core ARM was not too far behind the more powerful PandaBoard ES.
A look at the memory performance... Though with the varying memory configurations across the test platforms, these numbers are not too useful aside from some basic reference.
