ARM has announced its new Cortex-A78 architecture that will power most Android flagship smartphones in 2021. Interestingly, it has also branched out into extra-performance cores with the launch of its new Cortex-X1 borne out of its new Cortex-X Custom Program.

UK-based ARM has officially launched its new Cortex-A78 architecture, which will form the basis of flagship chip designs from the likes of Samsung and MediaTek among others in 2021. This year, however, the Cortex-A78 will also be joined by an additional special high-performance custom variant from its own in-house Cortex-X Custom Program. The new Cortex-X1 chip takes a similar approach to custom ARM-based chips from Apple and Qualcomm in that it seeks to optimize the architecture further for high-performance.

The Cortex-A78, codenamed Hercules, is the latest iteration of its Austin-family CPU architecture that was first introduced in the Cortex-A76 three years ago. It is designed for high-end performance at optimal efficiency and should deliver 20 percent greater sustained performance than the Cortex-A77. The performance and efficiency gains will come from a combination of architectural refinements along with the inherent benefits of shifting to the latest 5nm fabrication nodes.

The new Cortex-X1 is a direct response to the further customized and optimized chips that you find in Apple’s A-series designs and chips like Qualcomm’s Snapdragon 8xx series. The Cortex-X Custom Program team that actually works with Apple and Qualcomm on their customized designs is responsible for this new high-end design. It is good for a boost to 30 percent in performance over the previous generation and could find its way into Samsung’s Exynos chip line. Its existence could explain why Samsung decided to abandon its own customized high-performance Mongoose cores.

2021 is shaping up nicely from a mobile CPU performance front. Read more about how ARM is also amping things up in the mobile GPU space here.

I have been writing about consumer technology over the past ten years, previously with the former MacNN and Electronista, and now Notebookcheck since 2017. My first computer was an Apple ][c and this sparked a passion for Apple, but also technology in general. In the past decade, I’ve become increasingly platform agnostic and love to get my hands on and explore as much technology as I can get my hand on. Whether it is Windows, Mac, iOS, Android, Linux, Nintendo, Xbox, or PlayStation, each has plenty to offer and has given me great joy exploring them all. I was drawn to writing about tech because I love learning about the latest devices and also sharing whatever insights my experience can bring to site and its readership.
