Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.

I have personally bought several $5 Pi Zeros. In fact, I’m pretty sure I’ve also bought at least a half-dozen Pi Zero Ws for $5 from Microcenter (pre-pandemic), even though their MSRP was $10 at the time. I distinctly remember them being super cheap, but also limited to one per customer (per trip) at that price, so I’d just pop in and grab one any time I was near the Microcenter.
