Wide and slow is expensive. Very expensive. That's why Apple can do it and nobody else is doing it (in mobile Qualcomm is _cutting_ cache from Arm reference designs and in servers Graviton and Ampere are also cutting cache). It is cheaper for a given performance level to clock your cores as far as they'll go and cheap out on the width of your core if you know your customers either won't or can't care about power efficiency (because they have no better alternatives).
