Armv8 is a major revision of the ARM architecture. Unlike its predecessor (Armv7), Armv8 introduced a 64-bit instruction set (AArch64). This allows processors to address more than 4GB of RAM and handle larger computational chunks per clock cycle. This architecture is found in virtually all modern smartphones (Snapdragon 888/8 Gen series, Apple M1/M2/M3, MediaTek Dimensity), SBCs (Raspberry Pi 4/5), and ARM-based servers (AWS Graviton).
