In single-threaded performance, the F1 is roughly 3x faster than a Pi 1 (700 MHz ARM11). But memory is similar (512 MB). For modern 32-bit, it's comparable to a low-end Intel Atom from 2012.
Historically, mobile operating systems and processors relied on 32-bit (ARMv7) architecture. Over the last several years, the mobile industry shifted dramatically toward 64-bit (ARMv8) architecture to support higher memory capacities, faster processing speeds, and tighter security frameworks. f1 vm 32 bit

No. Pricing is based on machine type, not architecture. In single-threaded performance, the F1 is roughly 3x
