23.1 20nm high-K metal-gate heterogeneous 64b quad-core CPUs and hexa-core GPU for high-performance and energy-efficient mobile application processor

Abstract

The demands for high-performance smart mobile devices are growing exponentially every year. Like the PC market, 64b CPUs are needed to meet this demand. Furthermore, mobile GPU performance is becoming increasingly important as mobile game graphics requirements are pushing the limits of GPU capabilities. For an enhanced mobile game user experience, a multi-core GPU is required. CPU/GPU power efficiency for longer battery life has been a major interest to consumers for many years. In order to support higher performance and power efficiency, two 64b quad-core CPUs with different microarchitectures and a hexa-core GPU are implemented using Samsung's 20nm gate-last high-k/metal-gate (HKMG) process.
