In the last few days, we finally got some A20 Pro results and the numbers are impressive... reaching 4000 in single-core (one thread) performance. For comparison, the best that you can do with an x64 AMD or Intel processor is something like the Ryzen 9 9950X3D2 at about 3,163 which would be somewhere between the A18 and A19.
