Overkill hardware is OK with me. As long as it meets the need and has good battery life, I’m happy, but I don’t see overkill as a selling point.
My iPhone is absolutely overkill in the CPU department. I never push its capabilities. but I didn’t buy it for the benchmarks. I bought it because it’s a pretty good phone.
Not sure about this pro, but the previous models had kinda lacking battery life in some workloads because the CPU was just too damn powerful (and power hungry)
