I also see this issue.
I benchmarked my Mac Pro’s Radeon Pro 580X against this simple CNN model: https://github.com/macports/macports-ports/pull/12678
Apple GitHub tensorflow_macos alpha3: 5 s/epoch
PyPi tensorflow-macos v2.6 + tensorflow-metal v0.2: 15 s/epoch (3X slower)
Mac Pro 12-core Xeon W CPU: 10 s/epoch
Tesla V100: 1 s/epoch
I conclude that there are still some significant alpha-release issues with tensorflow-macos/tensorflow-metal.
