I just ran Geekbench on my MacBook Pro (Retina, 15-inch, Mid 2015).
Here are how the CPU scores compare:
2015 2.8Ghz i7 -> https://browser.geekbench.com/v4/cpu/1046050 (Single-Core: 4414; Multi-Core: 14376)
2016 2.9Ghz i7 -> https://browser.geekbench.com/v4/cpu/1043648 (Single-Core: 4276; Multi-Core: 13681)
Here are how the GPU scores compare:
2015 m370x -> https://browser.geekbench.com/v4/compute/228700 (OpenCL Score: 38345)
2016 460 -> https://browser.geekbench.com/v4/compute/228591 (OpenCL Score: 58496)
TLDR; 2015 CPU > 2016 CPU, 2015 GPU < 2016 GPU.
Personally, I ordered the 2.9Ghz, 460, 512GB version of the 2016 15". I'm glad we get an extended testing period for the Holidays; however, I'm disappointed that it isn't a clearer victory for the 2016 model.
