Stacked against (under) the P10, this new Huawei comes with some beefed up dimensions: 155 × 73.9 × 7.8 mm (6.10 × 2.91 × 0.31 in) and 180 g in weight.

Flipped over, we see evolution in action: Two cameras bad, three cameras good!

The 40 MP and 8 MP cameras work together to get a 3x optical zoom. The 20 MP monochrome camera brings more details and extra sharpness.

Since the P20 Pro's "extra" cameras live on the back, and it doesn't need Face ID hardware, its notch takes up a bit less real estate than the iPhone X it takes after (on the right).

Sizing aside, there's also some interesting notch geometry to consider.
