A basic comparison from CPU Monkey :
http://www.cpu-monkey.com/en/compare_cpu-intel_core_i5_6360u-581-vs-intel_core_i5_6267u-584
(basic config cpu for no touch bar on left, with touch bar on the right).
It seems that in single thread you have about 90-94% of the performances. in multi thread you are around 80%.
Also, like mentionned above. the considerably lower power consumption with a bigger battery (I assume it is because of the space saved by the secure enclave, touch bar, thunderbold ports and a smaller heatsink.) should give you better battery life.
However on Apple website it's weird that it's 10 hours for both. It's almost impossible that they both have the same battery life. Probably Apple didn't want to show a spec where the "cheap" (cheap relative to the other one
) is better.
Personnally I already ordered mine (the no touch bar MacBook Pro). I need a laptop asap, and also I have a good gaming PC tower at home so if I need to encode a video I don't need my MBP or something very demanding I don't have to do it on my MBP.
