Does CoreML on a mac run in 32fp on GPU?

I'm on a 2019 Mac Pro with AMD Pro Vega II Duo and wondering if my CoreML models will run in 32 bit floating point on this GPU, or is it restricted to 16bit due to compatibility with iPhones?


I'm getting wildly different results between CPU and GPU results on here.

Does CoreML on a mac run in 32fp on GPU?
