Not entirely sure what the difference is between the top speced 13" pro and air, the air is 1k cheaper and the parts are the same, aside from the touchbar and better cooling.
Thanks! Looks like the differences are:
- Iris graphics 645 on the pro vs iris graphics on the air
- i7 cpus are clocked a little higher on the pro, which according to this benchmark is about 12% faster (https://appleinsider.com/articles/20/05/04/compared-2020-13-...) .
The big question on Air vs Pro is what the thermal budget is. Generally, I've found that Airs will down-clock pretty quickly when running computationally intensive work for more than a minute or two. Pros have more ability to dissipate heat, which lets them run faster for longer.
