ARM Cortex-X3 and Cortex-A715 unveiled for next year’s flagship SoCs

We don’t know yet if there will be any 3nm flagship processor in the next year. Apparently, companies such as Qualcomm and MediaTek will stick with the 4 nm standard for another year. But this can easily change as TSMC is planning to begin its mass manufacturing of 3 nm chips, and Samsung already started. However, one thing we know, is that next year’s flagship SoCs will bring the next generation of ARMv9 cores to surpass the Cortex-X2 and Cortex-A710. As a result, ARM has already unveiled the new Cortex-X3 and the Cortex-A715 cores which will pave the year for next year’s flagship.

The Cortex-X3 and Cortex-A715 are here as the company’s second generation of ARMv9 processor cores. The company decided to not bring a new generation for the Cortex-A510 and is making some small adjustments. This is not a big surprise, after all, the ARMv8 standard stuck with the Cortex-A55 cores for years. So let’s focus on the big novelties presented today.

ARM Cortex-X3 and Cortex-A715 bring many improvements

Gizchina News of the week

ARM introduces the Cortex-X3 as its BIG core for flagships. This is the company’s third year of double-digit IPC growth (Instructions per cycle). Just like its predecessors, the Cortex-X3 will ensure peak performance. In comparison to the current flagship SoCs (Snapdragon 8 Gen series, Dimensity 9000, Exynos 2200) that have the Cortex-X2, the new standard will bring a 25% jump in performance. As for Windows on ARM designs, the improvements mean 34%.

The new Cortex-A715 core completes ARM’s transition away from 32-bit processors. This allows the engineering team to make the instruction decoder hardware 4 times smaller. The company states that the ARMv9 standard is more predictable and regular than ARMv8 and the new cores have full support for it. The Cortex-A715 is 20% more power-efficient than the Cortex-A710 at the same performance. It can deliver 5% more performance for the same power usage.

Last but not least, the Cortex-A510 got a small optimization to be 5% more power efficient in comparison to the 2021 branch. We expect these chips to appear in the upcoming Snapdragon 8 Gen 2 SoC, in the Exynos 2300, and MediaTek’s next flagship SoC.
