Arm Launches New Cortex-A78C CPU That Could Power Laptops
Arm has announced a new CPU variant that could be seen in laptop SoCs. The Arm Cortex-A78C is a variant of the high-end Cortex-A78 that will power the next generation of flagship smartphones. The company had launched the Cortex-A78 in May of this year as its most premium Cortex-A CPU, which it claims offers a sustained performance improvement of 20 percent and a 50 percent increase in power savings over the Cortex. -A77 from last year. While the Cortex-A78 cores are intended almost exclusively for smartphones, Arm says the new Cortex-A78C will power the next generation of mobile devices, such as always-on laptops.Arm made the announcement through a company. blog post, which revealed that the new Cortex-A78C will support up to 8 large groups of CPU cores for “more homogeneous large multi-core computing.” In comparison, Arm’s high-end Cortex-A78, which is expected to be part of Qualcomm Snapdragon 875 and Samsung Exynos 1080 Smartphone SoC: Supports 4 large CPU cores and 4 small CPU cores (Cortex-A55) in Arm’s proprietary DynamIQ arrangement.

The company says the new more flexible octa-core configuration of the Cortex-A78C can scale multi-threaded performance that would improve gaming and productivity. Like the Cortex-A78, its new C variant is also compatible with the recently released Mali-G78 GPU. The new CPU also increases the L3 cache to 8MB, which could translate to higher performance, especially when working with large data sets, the publication says.

Arm also says that the new Cortex-A78C CPU improves data and device security and that its Pointer Authentication Code (PAC) can significantly reduce vulnerabilities that allow attackers to take over the flow of software control. The company says it will help keep data safe even when installing third-party apps.

Arm hasn’t clearly said if its new Cortex-A78C CPU will be part of the SoCs that power laptops or mobile gaming devices any time soon. If that happens, it will be interesting to see how the Cortex-A78C in laptop processors compares to the performance of Intel processor cores.
