out-of-order superscalar
A superscalar processor is a CPU that implements a form of parallelism called instruction-level parallelism within a single processor. In contrast to a scalar processor, which can execute at most one single instruction per clock cycle, a sup ...
pipeline. The Cortex-A75 serves as the successor of the
Cortex-A73, 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

ARM has also collaborated with
Qualcomm for a semi-custom version of the Cortex-A75, used within the
Kryo 385 CPU.
This semi-custom core is also used in some Qualcomm's mid-range SoCs as
Kryo 360 Gold.
