TheARM Cortex-A75is acentral processing unitimplementing theARMv8.2-A64-bitinstruction setdesigned byARM Holdings'sSophiadesign centre. The Cortex-A75 is a 3-wide decodeout-of-ordersuperscalarpipeline.[1]The Cortex-A75 serves as the successor of theCortex-A73,designed to improve performance by 20% over the A73 in mobile applications while maintaining the same efficiency.[2]

Design
editAccording 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 increasedTDPenvelope of 2 W, enabling increased performance.[3]
The Cortex-A75 andCortex-A55cores are the first products to supportARM's DynamIQtechnology.[2][3]The successor tobig.LITTLE,this technology is designed to be more flexible and scalable when designing multi-core products.
Licensing
editThe Cortex-A75 is available asSIP coreto licensees, and its design makes it suitable for integration with other SIP cores (e.g.GPU,display controller,DSP,image processor,etc.) into onedieconstituting asystem on a chip(SoC).
ARM has also collaborated withQualcommfor a semi-custom version of the Cortex-A75, used within theKryo 385CPU.[4]This semi-custom core is also used in some Qualcomm's mid-range SoCs asKryo 360 Gold.
