The benchmarks for Raspberry Pi 2 and Raspberry Pi 3 show far faster performance than the Raspberry Pi 1 / Zero. Using the graphical desktop and 4 GB of RAM, the Raspberry Pi 4 is useful for modest desktop use. The new CPU-direct USB and Ethernet of the Raspberry Pi 4 brings drastically faster IO.
The Raspberry Pi Zero has an ARMv6 single core CPU but much lower idle power for battery-powered applications.
Beaglebone deterministic IO due to the PRU is a key advantage for certain applications. The Beaglebone DDR3L RAM, and ARMv7 CPU is nearly twice as powerful as the Raspberry Pi Zero, native Ethernet, onboard SSD (eMMC), better onboard I/O (for local sensors), etc. However, CPU or GPU demanding tasks should consider the latest Raspberry Pi or Intel NUC, etc. instead.
