SPEC is a better cross platform benchmark, since it's an industry standard and was designed just for cross platform testing.
>Overall, in terms of performance, the A13 and the Lightning cores are extremely fast. In the mobile space, there’s really no competition as the A13 posts almost double the performance of the next best non-Apple SoC. The difference is a little bit less in the floating-point suite, but again we’re not expecting any proper competition for at least another 2-3 years, and Apple isn’t standing still either.
Last year I’ve noted that the A12 was margins off the best desktop CPU cores. This year, the A13 has essentially matched best that AMD and Intel have to offer – in SPECint2006 at least. In SPECfp2006 the A13 is still roughly 15% behind.
I think performance per watt is going to be just as important as overall performance. Apple's "little" cores were a new design in the A13, and compare very well against stock ARM cores on a performance per watt basis.
>In the face-off against a Cortex-A55 implementation such as on the Snapdragon 855, the new Thunder cores represent a 2.5-3x performance lead while at the same time using less than half the energy.

It will be interesting to see how much performance they can get when they are on a level playing field when it comes to power and cooling constraints.
