Libretro performance question: Cubox-i 4Pro vs. Odroid C2?

Has anybody directly compared Cubox-i 4Pro to Odroid C2 concerning Libretro performance? I have both available and am wondering which one I would get the best performance from.

The hardware overview seems to suggest that the Odroid C1 has imx-6 (which Cubox-i is based on) beat. I assume the Odroid C2 would perform even better than the C1, but what version of the imx-6 is the table refering to? The 4Pro uses the four-core SoC, does that make a difference?
