Apple's done an amazing job of unf*cking the confusion of Ghz specs and decoupling form factor and performance tradeoffs for regular human beings.
The single-core baseline performance is the same for all form factors.
No one has to decide on whether they need a "desktop" or "laptop" or "tablet" or "all-in-one" based on basic performance. It's all the same, even up to workstations. There's no FOMO.
If they need higher multi-threaded or gpu performance or more memory/storage options, it's available in a higher tier: Pro, Max or Ultra. Desktop, laptop, or (maybe soon) all-in-one.
To
@Abazigal's point. How does any other manufacturer compete with this?
