Intel Core i7 720QM Quad-Core Ubuntu Linux
Ubuntu 12.04 LTS Precise Pangolin Linux benchmarks of an OMAP4660 PandaBoard ES with GCC and LLVM C/C++ code compilers. For kicks also compared to an Intel Core i7 720QM with GCC 4.6 from Ubuntu 12.04 LTS using a Lenovo ThinkPad notebook. This is a nice qua-core Intel CPU under Linux with Hyper Threading on 3.2 kernel.
