The only thing is, will Apple fumbles around as competitors catching up? That's the thing the Apple sometimes does , stumbling on its own due to form over function, or some focus on virtue signalling. Is Apple can maintain their momentum, it would be tough for Intel to catch up unless they have a breakthrough in architectural change.
We need to see more products to understand what Apples plans are. It’s still not clear whether the M1 lineup is representative for their long term strategy or whether it was a one time test of horizontal scaling technology. I still think that if Apple is serious about desktop their next step will be vertical scaling and possibly new generation of high-perf cores. It’s also notable that they have been steadily improving their E-core technology every year.
