I like this one the best so far: http://arstechnica.co.uk/apple/2016/11/macbook-pro-touch-bar-13-15-inch-touch-bar-review/. In it, they not only give the specs, but also explain what they mean in real world use. For example:
- The low-end Pro uses a 15W Core i5-6360U CPU with an Intel Iris 540 GPU; the high-end model uses a 28W Core i5-6267U CPU with an Intel Iris 550 GPU. The difference, aside from small boosts to CPU and GPU clock speeds, is that the 28W model can run faster for longer and throttle less frequently. The 15W model can also consume less power.
