big.LITTLE

A feature of computer architectures developed by ARM Holdings that includes a hybrid of high-performance and high-efficiency cores. Both types of cores can access the same memory and tasks can be switched between core types on demand. This architecture can enable ARM-based systems to swap tasks and processes between core types for greater flexibility and responsiveness of the foreground task. Deactivation of the high-performance cores also has serious benefits for standby time and reduces thermal loads in mobile devices. Unlike in ARM, in the x86-based CPU (from Intel and AMD) all cores have similar performance / efficiency characteristics.
