My recommendation here is to wait a couple of months until Ryzen 3 comes out in laptops. While an IPC boost is nice (rumors are between 10% - 20%) the real reason I say this is because the new 7nm process should net a significant reduction in energy consumption. AMDs demo of Zen 3 in January showed their 8c/16t CPU performed almost identical to Intel's 9900k with 1/3 less the power consumption.
