|Zero||ARMv6||512 MB LPDDR2||low power consumption, single-core CPU.|

The benchmarks for Raspberry Pi 2 and Raspberry Pi 3 show far faster performance than the Raspberry Pi 1 / Zero. Using the graphical desktop, 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.
Beaglebone‘s 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.
Intel Edison was a better choice for energy-budget conscious tasks than the Raspberry Pi and the Beaglebone Black due to the Edison’s dual-core x86 CPU, fast RAM, and extremely favorable energy efficiency. The Edison may have run 10-20x as long or more on battery than most Raspberry Pi models or Beaglebone Black.
The Raspberry Pi Zero has a fairly limited ARMv6 single core CPU, but much lower idle power for battery-powered applications.
Former Raspberry Pi models
These models shouldn’t generally be used anymore unless there’s a specific reason:
|1||ARMv6||512 MB LPDDR2||high power consumption, single-core CPU.|
|2||ARMv8 (A53)||1 GB LPDDR2||no onboard wireless.|
|3+||ARMv8 (A53)||1 GB LPDDR2||quad-core CPU, GPU, Bluetooth 4.2 / 802.11ac, gigabit Ethernet|
