Processor differences on 13" MBP?

[beansbaxter]

The 13" MBP without Touch Bar has this processor option:
- 2.5GHz dual-core Intel Core i7 processor, Turbo Boost up to 4.0GHz

The 13" MBP with Touch Bar has this processor option:
- 3.5GHz dual-core Intel Core i7 processor, Turbo Boost up to 4.0GHz

I understand the baseline processor speed for the Touch Bar version runs at a higher clock speed, but both of these processor options increase to 4.0Ghz when needed.

So what's the pros and cons of one over the other if they both run under heavy load at the same 4.0Ghz speed?

What other differences between these processors/machines am I not seeing?

Thanks in advance.

It's about the TDP. The non touch bar should last less ar maximum frequency during CPU intensive tasks but on paper, anandtech reported that they both prettt much last the same.

You get a better battery and less energy hungry processor on the non touch bar so I'll get that one.

It's the exact opposite. Turbo Boost can only kick in for short bursts, and under heavy or sustained load, the machines throttle to their base clock speeds.

The Touch Bar model uses a higher TDP CPU (28W) and has a two-fan cooling system, compared to the 15W CPU and single fan in the non-TB model, and thus will maintain its higher clock speed for longer when doing intensive tasks.
