What do you mean? How did you arrive to that conclusion?Gonna need a lot more than 8 performance cores for it to be useful, even if those are super fast. I am expecting 30 odd cores in my next desktop and perhaps at least 12 in a MacBook Pro.
iPad Pro’s 2018s chip is faster, efficient and more performant across all the board than 2020s active cooled intel 10th gen used on high end Macbook Pros 13”. There are videos showing iPad Pro editing 4K+ footage real-time in situations where $2k, $5k and $10k worth desktops chugged on that specific task.
I think it will just get better exponentially. Besides, 12 cores is already a very high number for what tends to be still mostly a single core driven world except in parallelize-able situations.
