Edit: originally, I wrote that my CPU is a Ryzen 5 3600X, but it is an 5600X.
The A500 is about half the speed of the 2070, so that wouldn’t be so bad (my 1060, which is about 50% faster, so halfway between that laptop GPU and your 2070, is 5-10x faster than my Ryzen 5 5600X CPU). However, it has half the RAM, so you can get more tiling, which can slow down processing dramatically.

The AMD CPU in the new laptop seems to be > 50% faster than the Intel in the old one:

It’s also about 40% faster than the Ryzen 5 3600X, which I referenced here before.
I then remembered that I have a Ryzen 5 5600X, not 3600X, but even that is a bit slower than the new AMD Ryzen 7 PRO 7840U.
