The guide doesn't assume access to specialized hardware. Experiments and iterations with all of those algorithms can be done on a normal CPU that anyone has. :)

Quote:

"Iterate fast in simple environments. To debug your implementations, try them with simple environments where learning should happen quickly, like CartPole-v0, InvertedPendulum-v0, FrozenLake-v0, and HalfCheetah-v2 (with a short time horizon—only 100 or 250 steps instead of the full 1000) from the OpenAI Gym. Don’t try to run an algorithm in Atari or a complex Humanoid environment if you haven’t first verified that it works on the simplest possible toy task. Your ideal experiment turnaround-time at the debug stage is <5 minutes (on your local machine) or slightly longer but not much. These small-scale experiments don’t require any special hardware, and can be run without too much trouble on CPUs."
