No, the minisforum will be much more powerful. I think that CPU will be roughly twice as powerful and the GPU included (6600M) similarly roughly twice as powerful.

As the other commenter said, there are other handhelds, some getting better chips. But for your use case, you could also choose a small gaming pc or a laptop.

If you would get use out of a gaming laptop separate from attaching to your TV then that's pretty attractive choice because it does everything the mini PC does without that much more space.
