What do you need your Laptop for? If you're only working on your Laptop and not use it for PC gaming, a Ryzen U series should suffice. After all, a Ryzen 7 4700U crushes both the i7 10710U and the Ice Lake based 1065G7, and even keeps up with the 9750H in some tasks:
Keep in mind that the Laptop with the 4700U here is a bidget model which only costs $650, while it's competitors cost about twice as much. Tiger Lake really can't come soon enough for Intel, both on Desktop and Laptop.
What crazy is if you look at like notebookcheck.net, cinebench R15 scores.
AMD ryzen 4700U (15w mobile cpu) = singel thread score : 182 , Multi thread score : 1174.
Intel i7 7700k (91w desktop cpu) = singel thread score : 192 , Multi thread score : 938.
A 4700U basically will feel like your running a i7 7700k at stack speeds.
The Ryzen 9 4900HS (35w) is actually close to a stock Intel i7 9700k in terms of performance.
