The movie Toy Story needed top-computers in 1995 to render every frame and that took a lot of time (800000 machine-hours according to Wikipedia).
Could it be possible to render it in real time with modern (2025) GPUs on a single home computer?

With a modern game engine and PBR shaders you can definitely get the same look as the movie. If you try to render it exactly the way they did it with a software renderer on the CPU then maybe. Their rendering software, Reyes, didn’t use raytracing or path tracing at all. You can read about it here

I only skimmed it but it seems what they call micro polygons is just subdivision. Which can also be done realtime with tessellation.
