Yep, there are many reimplementations. Here is a reimplementation that swaps out a neural net with a GBDT to address compute costs:

How does the performance of this version compare?

Depends on game/environment and—since it's using a GBDT and not a NN—how good you are at feature extraction/selection for your problem.

High level, I'd say it's a good way to test a new environment w/out spending time/effort on GPUs until you understand the problem well, and then you can switch to the time/money costly GPU world.

Imagine its perfect for Computer Backgammon, but overfits higher dimensional spaces ;)
