Arm outs latest CPU, GPU designs

Arm, a British semiconductor company who makes the brains of the majority of the mobile devices, has recently revealed their latest CPU configurations. Which include Cortex-X4, Cortex-A720, and Cortex-A520.

These new cores are designed to strike a balance between performance and efficiency, enabling them to collaborate and optimize performance by allocating tasks effectively among different cores.

The biggest change in Arm’s Total Compute Solution this year is that their cores are now AArch64 only, meaning they have transitioned to 64-bit only, leaving behind the old 32-bit Arm instruction set.

Since 2019, Google has required all updated Android apps to be uploaded as 64-bit binaries, placing pressure on 32-bit applications.

Arm’s Cortex-X4 is the company’s fastest CPU core yet, designed for speed. It boasts a 15% improvement in performance over its predecessor, Cortex-X3, at the same power level. It is ideal for handling heavy single-threaded tasks and is expected to significantly improve performance even further, potentially hitting clock speeds of 3.4GHz.

Meanwhile, the Cortex-A720 core is optimized for efficiency and can handle multi-threaded tasks. It is 20% more efficient than its predecessor, the Cortex-A715, making it ideal for power-conscious devices.

Lastly, the Cortex-A520 is an in-order core that is highly efficient and takes up minimal space on silicon. It enables two cores to share execution units, which makes it suitable for handling background tasks in high-end chipsets.

Arm has also unveiled new GPUs with their “5th Gen” architecture that offer a 15% increase in peak performance and average performance per watt. These GPUs incorporate the Deferred Vertex Shading pipeline which improves performance while reducing memory and power usage.

Arm’s latest CPU and GPU designs are anticipated to be released this year and in early 2024. In essence, these new cores will serve as the foundation for the next generation of mobile processors.
