What is the depth reached by chess-AI agents on a regular computer?

Question

I'm looking for some reference for the number of lookahead steps typically used by chess agents (Stockfish / Leela Chess Zero / others?)

From a quick search, I found that the answer depends on:

1. complexity of position,
2. computer hardware/processor speed,
3. efficiency of software/graphics interface,
4. time given to the chess engine.

With somewhat mediocre hardware, a depth around 15 ply's in one second is typical.

The NPS value for the Stockfish engine: 49,473 kN/s (calculating 49,473,000 positions (nodes) per second).
