I bought three laptops with i5 i5 10210U, , i7 i7-10510U and Ryzen 7 4700. Same model thinpad e15 - differing only in processors. Ryzen in synthetics tests totaly dominated under i5 and is slightly faster than i7. The difference is not noticeable by eye, the are all laptops are very fast.
But the Ryzen laptop is the cheapest of the three.
I concluded for myself that I will buying laptops on AMD processors
