> It’s far less capable of running intensive tasks than any of Apple’s M‑series chips or any moderately powered Intel or AMD processor.”

This is false. The A18 Pro has much better single core performance than the M1 and slightly better multi core performance. Most people would see no noticeable benefit to a faster CPU. Especially with a fanless design, the additional cores of a comparable M-series chip would give you better burst performance for some workloads, but possibly not much improvement in sustained performance.
