Leela vs Stockfish nnue style

I hear that M1 and M2 chips have only enough TLB for 32MiBs of memory, so that tracks. 50% higher for M3, so still pretty bad. Still interesting that it regresses so much compared to Intel/AMD though, because it's still pretty comparable without large pages.

What is TLB?

Children, children.

I've benched the M2 Ultra (should be at least as fast as the M3 Max) and it got 17Mn/s

Not great performance.

Excellent performance to power ratio though, but I do think this argument is overplayed.

Yup it's a bug with apple's ram hash function. Using the command
"bench 512 8 2000 default movetime"

M2 Pro, 12‑core CPU, 32GB memory
gets the following result

Total time (ms) : 90548
Nodes searched : 2218332923
Nodes/second : 24498972

This is on par with some i9-13900 machines (from Ipman Chess benchmark listings)
So the M2 Ultra should bench even higher than that result

Much better: Buy 16-inch M3 MAX MacBook Pro.

It appears that you may have forgotten to enable NNUE in the bench command. To enable NNUE, you must add ‘nnue’ to the bench command as well. Unfortunately, the M2 Pro is not capable of achieving 24Mnps.

If you wish to run the same test with 512MB cache, you should most likely use the following command:

bench 512 8 26 default depth nnue

However, you will likely get slightly better results by using all 12 cores. In that case, you can use the following command:

bench 512 12 26 default depth nnue

Regarding your question, it is not appropriate to generalize a group of people based on their choice of technology. It is important to respect everyone’s preferences and choices

Generalize a group of people? I don't understand. The question refers to the playing style of two engines (not people).

LC0 BT4 works fine on MacBook Pro 16-inch M1 MAX or higher.

Define "works fine" compared to a similar priced gaming laptop with Nvidia 2024, running BT4... ... Overpriced & underperforming I would say in so many computing areas.
