The Cortex-X3 and Cortex-A715 cores are the next flagship CPUs from ARM. The new cores come with a significant performance boost and will power premium Android phones in 2023. Continue reading to learn more about the Arm 2nd gen v9 CPUs.

Arm 2nd gen v9 CPUs Overview:

The Cortex-X3 builds on last year’s Armv9 architecture. Alongside this, the company has also introduced a new Cortex-A715 core and an improved Cortex-A510 core. 

Cortex-X3

To begin with the elephant in the house, the Cortex-X3 offers a 25% boost in performance over the current best Cortex-X2. It is also said to be more efficient, and capable of delivering the same level of performance while consuming less power.

Arm Cortex-X3 Performance Gain

Furthermore, Arm claims to deliver up to 34% higher single-threaded performance than the latest mainstream laptops. Android Authority compares it to the Intel Core i7-1260P, a power-hungry 28W CPU.

Cortex-X3 also improves upon DynamIQ Shared Unit (DSU-1010) platform and can now support up to 12 cores and 16MB of L3 cache. This allows for more scalability, allowing Arm CPUs to be adapted for everything from phones to high-end laptops.

Arm Cortex-A715 Performance Gain

The Cortex-A715 core, on the other hand, also brings a fair set of improvements; the most significant of which is the transition from 32-bit to 64-bit processors. This is Arm’s roadmap for fully transitioning to 64-bit, and we will see 64-bit only Android smartphones starting next year. It has a 20% higher energy efficiency than the last year’s Cortex-A710 cores. The performance increase is 5% and is said to match the performance of the Cortex-X1 CPU from 2020.

Arm has also upgraded the Cortex-A510 core for energy efficiency (5% more efficient than the previous generation). This should result in better battery life. 

Composition

With Arm releasing new CPUs, the 2023 flagship processor cluster will have Cortex-X3, Cortex-A715, and Cortex-A510 cores. Chipmakers (Qualcomm, MediaTek, and Samsung) may use 1+3+4 designs like the current flagship chips, or they can also go with 1+4+4 or 2+2+4 cluster designs.
