Not so. Apple's new mobile processors are routinely the fastest processors in the world (single threaded) when they come out. The A17 pro is currently the 17th fastest CPU, and the M3 (which is in MacBook airs and iPads) is number 2.
Sure these don't have the scope or number of transistors of like an NVIDIA Blackwell or something but in terms of performance/watt these are ultra high-end ICs.
