ARM Cortex-A78

The ARM Cortex-A78 is the successor to the ARM Cortex-A77. It can be paired with the ARM Cortex-X1 and/or ARM Cortex-A55 CPUs in a DynamIQ configuration to deliver both performance and efficiency. The processor also claims as much as 50% energy savings over its predecessor. and efficiency improvements to instruction schedulers, register renaming structures, and the re-order buffer. L2 cache is available up to 512 KB and has double the bandwidth to maximize the performance, while the shared L3 cache is available up to 4 MB, double that of previous generations. A Dynamic Shared Unit (DSU) also allows for an 8 MB configuration with the ARM Cortex-X1. == Variants ==

Cortex-A78C The Cortex-A78C is targeted for productivity and gaming applications, it increases the max core support from 4 to 8 cores and from 4MB to 8MB of L3 cache. Cortex-A78AE The Cortex-A78AE is targeted for security/safety and automotive applications. == Licensing ==

The Cortex-A78 is available as a SIP core to licensees whilst its design makes it suitable for integration with other SIP cores (e.g. GPU, display controller, DSP, image processor, etc.) into one die constituting a system on a chip (SoC). == Usage ==

The Cortex-A78 was first used in Samsung Exynos 2100 SoC, introduced in November and December 2020 respectively. The custom Kryo 680 Gold core used in the Snapdragon 888 SoC is based on the Cortex-A78 microarchitecture. The Cortex-A78 is also used in the MediaTek Dimensity 1200 and 8000 series. The device is also used in Nvidia's BlueField-3 and 3X DPUs, and in the HiSilicon Kirin 9000s, released in August 2023. The Cortex-A78C is used in Nvidia's T239 SoC that powers the Nintendo Switch 2. == See also ==
