It’s rather underwhelming to be honest. And even with this Apple Silicon transition, it‘d be a slow, steady transition for Mac to be iOS device. With its “3x GPU improvement” would it be able to run elite PC games? Or chugging into PS5 performance? It’d be 10 years before that happens.
I’ve been waiting for Apple Arcade to be a fully matured games store that’s able to match at least PS4 performance. Still can’t see that happens anytime soon.
The mission of Apple Silicon is clear, the best industry-leading performance per watt. That’s pretty much the keyword.
Hard to know how the CPU & GPU perform, but if it has just 8GB unified memory (RAM & VRAM) I wouldn't expect much from it. TBH, I'm not sure I'd use any Mac with just 8GB any more, never mind 8GB with some of that used for video. Then add in things like Rosetta 2 which are likely to have a RAM overhead if you're using any Intel apps/games (It's especially unlikely that Intel Mac games are going to be ported).
