No, I mean that's not relevant to compare what the hardware can do. It's like how the PS3 was super hard to program but in the end it was producing more impressive results than the Xbox360. This was not a surprising result, it was to be expected from the hardware. It's not that different from what is happening here, benchmarks running on x86 emulation on engines running compatibility layers for Metal are not representative of the hardware.
With the difference that Apple HW performance might be "good enough" for 3rd party software vendors if they take into account the extra development burden for the platform. Anyway some of those benchmarks were already using Metal and are still behind.
