It shows incredible performance gains compared to OpenGL on my MacBook Pro Retina even in high-level tests.
NVIDIA GT650M:
Manhattan: OGL 24 FPS METAL 30 FPS 25% Faster
T-Rex: OGL 43 FPS METAL 70 FPS 62% Faster

The low-level tests show between 70% and 250% improvement but that was obviously going to happen. I was surprised to see this much improvement even in high-level tests.

Then I tested with my Mac Pro:

AMD D700:
Manhattan: OGL 59 FPS METAL 115 FPS 94% Faster
T-Rex: OGL 59 FPS METAL 118 FPS 100% Faster

This was even more jawdropping.

Hm, I was waiting for it, but I don't see anything on their website... where did you get that version?

I ran the tests on my iMac 5k (2014), with the AMD Radeon R9 M295X, using both the OpenGL version and the Metal version. Here is a comparison of the results from one of the tests:

T-Rex test OpenGL On-Screen: 59.891 FPS
T-Rex test Metal On-Screen: 108.493 FPS

The On-screen version runs at the native resolution of the system.

T-Rex test OpenGL Off-Screen: 386.23 FPS
T-Rex test Metal Off-Screen: 530.702 FPS

The off-screen version runs at 1080p allowing comparisons between different systems.

My results on M370X show little surprise: a) AMD's OpenGL implementation is quite decent b) Metal's driver overhead is MUCH lower c) Metal version is significantly faster d) there are some issues with the Metal implementation, as it is reported slower in certain artificial tests. So far, looks good. Metal is a very nice API to work with, porting game engines from OpenGL to it is fairly trivial, and while Metal's feature set leaves much to be desired (its basically DX9 with some additional features), I am sure Apple will bring it up to the level of OpenGL, DX12 and Vulkan in the future releases.
