Dwarf Fortress mostly has two bottlenecks for historical reasons: It's single-threaded and is a 32bit application, meaning it can use less than 3GB Ram. So interestingly a modern gaming PC could be worse at running Dwarf Fortress than an older one, as nowadays multithreaded performance is prioritized and anything beyond 4GB Ram doesn't help you. And I guess at a certain world size good performance would need less detailed simulation in other parts of the game world.
