[2][3][4] The processor is built on a standard Cortex-A roadmap and offers a 2.1 GHz (5 nm) chipset which makes it better than its predecessor in the following ways: There is also extended scalability with extra support from Dynamic Shared Unit for DynamIQ on the chipset.
To offset this smaller L1 memory, the branch predictor is better at covering irregular search patterns and is capable of following two taken branches per cycle, which results in fewer L1 cache misses and helps hide pipeline bubbles to keep the core well supplied.
The pipeline is one cycle longer compared to the A77, which ensures that the A78 hits a clock frequency target of around 3 GHz.
[citation needed] The Cortex-A78 was first used in Samsung Exynos 2100 SoC, introduced in November and December 2020 respectively.
[7][8] The custom Kryo 680 Gold core used in the Snapdragon 888[broken anchor] SoC is based on the Cortex-A78 microarchitecture.
