Cortex-A78C announced, ARM increasingly present on PCs
ARM Cortex-A78C was built on the basis of the Cortex-A78 for smartphones and tablets, but with some changes to deliver the performance required for workloads running on notebooks and other types of personal computers. ARM claims that laptops equipped with the Cortex-A78C will offer exceptional battery life, but will also be able to run demanding applications, such as professional productivity suites and games.

Cortex-A78C supports DynamIQ clusters of up to eight cores (with 256KB or 512KB L2 per core) operating at up to 3.30GHz and comes with up to 8MB L3 cache for maximize single-threaded performance and performance in applications with large data sets. To further improve performance, the new CPU features an increased snoop filter and can configure slicing to optimize times. Additionally, the Cortex-A78C offers advanced security features, such as Pointer Authentication (PAC), designed to reduce the possibility of Return-Oriented-Programming (ROP) and Jump-Orientated-Programming (JOP) attacks. ARM also recommends pairing its Cortex-A78C with its latest Mali-G78 graphics clusters to ensure great performance in games.
To a large extent, the Cortex-A78C resembles Qualcomm's Snapdragon 8cx and 8cx Gen 2 which feature eight Kryo 495 cores and the Adreno 680/690 GPU. Additionally, it will be particularly interesting to find out how ARM and Qualcomm's latest laptop offerings compare against Apple's future system-on-chip for its notebooks.
ARM's announcement indicates that the device is already there. available for developers. However, the first SoCs that integrate the processor will be available in at least a year, so don't expect Cortex-A78C-based notebooks until the first half of 2022.
