So If I load latest leela into a laptop (being about KGS 4k) I would expect
to demolished even on 9 stone handicap. Nice

4 TPU is 180 TFLOPS, or 45 TFLOPS each [1]

GTX 1080Ti is 11.3 TFLOPs [2], or 9 TFLOPS for the normal 1080.

So 4 TPUs are more like 15-20 times faster than a high-end gaming notebook.

(I'm being pedantic; I expect your main point still stands even if it is
20x. And if not, the AlphaZero results were at 5s/move - people wanting
a world-class game could give it 30s or even 60s/move.)

What does "best possible SW" mean? The one that isn't written yet? :-)

Zero was reportedly very strong with 4 TPU. If we say 1 TPU = 1 GTX 1080
Ti the Elo loss from the slowdown from 4 to 1 would still make it far
stronger than the best humans.

As for things that are available right now:

The latest Zen is very strong even without a GPU.

My bot was 8d on KGS with a GTX 1080 Ti and a Ryzen 1700 (roughly ~1000
USD hardware). I don't run on KGS anymore but people from Tygem told me
it is equal to lower ranked pros there, on a smaller system.

You can get very strong software right now, but nothing will change the
fact that better hardware always helps. The difference between a laptop
and a desktop with a real GPU will always be there.
