Chip used in TB 13": 2.9 GHz Dual Core Intel Core i5-6267u https://browser.primatelabs.com/v4/cpu/search?utf8=✓&q=6267u Chip used in non-TB 13": 2.0 GHz Dual Core Intel Core i5-6360u https://browser.primatelabs.com/v4/cpu/search?utf8=✓&q=6360u They both seem to hit ~7100 score. And both cost the same. $304. https://en.wikipedia.org/wiki/Skylake_(microarchitecture) The only difference is that: (1) 15W: more battery life (considering that non-TB has a bigger battery size) (2) 15W: may tend to throttle more. Interesting. Now it seems that the only real advantages that the TB version have are: (1) 2 extra ports (2) a touch bar (which may or may not be useful, depending on your usage). Graphics-wise, the HD 540 and HD 550 doesn't have much difference either (HD 550 is 5% faster), and both should be as fast as the Iris Pro 5200 on the 15" (2015) model, which is pretty good if you ask me.
