Was Tomb Raider demo running on A12Z or custom silicon?

It was kinda unclear with them jumping from talking about custom silicon, then showing A12Z in system info, then talking how powerful custom silicon is and showing Tomb Raider again. If this is new silicon then it's kinda unimpressive, basically around Renoir APU levels of graphics performance. Still fine for Macbook Air though, but I wonder what are they gonna do for more GPU power. Make a huge silicon? Couple with separate in-house dGPU? Or maybe they can still run it with AMD gpu?

I want to say A12Z, that supposedly has ~early current gen console level graphics so probably looks about right (particularly given its emulating an x86 program).
