The ARM Cortex-A73 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings' Sophia design centre. The Cortex-A73 is a 2-wide decode out-of-order superscalar pipeline. The Cortex-A73 serves as the suc ...
, designed to improve performance by 20% over the A73 in mobile applications while maintaining the same efficiency.
Design
According to ARM, the A75 is expected to offer 16–48% better performance than an A73 and is targeted beyond mobile workloads. The A75 also features an increased
TDP envelope of 2 W, enabling increased performance.
The Cortex-A75 and
Cortex-A55 cores are the first products to support
ARM's DynamIQ technology.
The successor to
big.LITTLE
ARM big.LITTLE is a heterogeneous computing architecture developed by ARM Holdings, coupling relatively battery-saving and slower processor cores (''LITTLE'') with relatively more powerful and power-hungry ones (''big''). Typically, only one "s ...
