This weekend when publishing preview benchmarks of NVIDIA's Tegra K1 from the Jetson TK1 development board, there were numerous requests by Phoronix readers to see this high-end ARM SoC pitted against the new AMD AM1 APUs. In this article are some benchmarks of Ubuntu 14.04 LTS on all of the AM1 Athlon and Sempron APUs compared to the Tegra K1 Cortex-A15 SoC.

Like this weekend's tests, the benchmarks in this article are primarily CPU bound as I'm still ready some ARM-compatible graphics and OpenCL tests. Those should be ready soon along with some power consumption numbers. Thus in this article it's mostly a comparison of the AM1 APUs with their dual and quad AMD "Jaguar" x86 cores compared to the Tegra K1 with its quad-core-plus-one Cortex-A15 configuration.
