You’re mistaken about GeForce Now - it streams games running in nVidia’s servers. If I remember correctly, based on Intel Xeon and their own Volta GPUs.

GeForce Now has its own library of streamable titles for purchase, but it also allows you to link your Steam (and others) account to authorize streaming of games you already own and happen to be available in their library. But they run remotely.

I was very impressed with it, and my comparisons between streaming from nVidia’s remote servers or my own gaming PC yielded negligible differences in visual performance and latency. Your mileage will naturally vary.
