They designed and built their own microcontroller. This chasing performance narrative doesn't make sense.
And let's be real, it doesn't have 25W power consumption. You can attach enough things to it to get to 25W if you try really hard but that's hardly the same thing. The latest cheapo Intel parts are contenders (at ~10W, where the pi 5 actually operates) and if you just want perf you're better off with that. But if you want a low-level connectivity, a rich community, docs, and tailor-made projects, you still want a pi.
