I’m fairly certain most of the cost there is in the machinery. The software should be more or less comparable (there’s no reason for it not to be anyway).

Why are you so certain?
While the hardware isn't exactly cheap, neither is the software. Gathering feedback from a bunch of pilots and incorporating it into the simulator isn't cheap. Renting out an A330 and a couple of pilots to run experimental validation isn't cheap - it costs >$50k an hour and you'll need hundreds if not thousands of hours. Validating each software release isn't cheap.

I'm working on second hand info but AFAIK it takes over a dozen modern networked server systems to provide the fidelity the simulators need (with multiple GPUs no less). The software isn't comparable simply because a consumer machine isn't powerful enough to run the real stuff and the quality of the simulators has absolutely sky rocketed in the last 20 years. The've been constantly upgraded to the point that a 747 simulator now costs more than the plane itself.
