Gpu: Arm’s new CPU and GPU cores promise increased performance with improved power-efficiency – Times of India

At Tech Day 2023, Arm, the company responsible for designing the foundational architecture for chipsets used in smartphones, tablets, and more, introduced new CPU cores – Cortex-A520, Cortex-A720, and Cortex-X4.
The Cortex-X4 is a high-performance core, while the Cortex-A720 and Cortex-A520 are mid-performance and power-efficient cores.
Arm Cortex-X4: 64-bit architecture, up to 40% efficient, and 15% gains in performance
The new cores from Arm only support 64-bit architecture, and there will be no revision to support 32-bit. All future smartphone chipsets and Arm SoCs in other segments will only support 64-bit architecture.
The ARM Cortex-X4 is a powerful and energy-efficient core that will be utilised in high-end smartphones and tablets. It can reach speeds of up to 3.4GHz and boasts a 2MB L2 cache, which is twice as large as the previous year’s model while offering up to 40% improvement in power efficiency, the Cortex-X3, which is being used in the likes of Snapdragon 8 Gen 2 and Dimensity 9200+ chipsets.
The Cortex-A720 is designed to provide sustained high performance while using less energy. Despite being as small as the Cortex-A78 from a few years ago, these CPU cores offer 10% more performance. This CPU core may be used in more mid-range and low-end chips. ARM expects a 15% increase in performance compared to previous generations.
The Cortex-A520 CPU core is ideal for smaller tasks and uses 22% less power than last year’s Cortex-A510. At the same power consumption level, Cortex-A520 cores can offer 8% more performance than Cortex-A510 cores.
Arm’s Cortex-A720 offers improved power efficiency, allowing for more mid-level cores and less reliance on smaller, power-efficient cores. This means a cluster can have more A720s for primary tasks, with a larger X4 for demanding tasks and a few A520s for lighter work. The standard configuration includes one X4, three A720s, and four A520s, but customers can adjust based on their workload and power needs.
New GPUs for smartphones, tablets, and more
ARM also introduced the Immortalis G720 GPU GPU for high-end smartphones and tablets, boasting a 52-67% increase in performance for ray-tracing tasks and a 5-52% improvement in VRS tasks compared to other GPUs. This GPU promises to provide better performance and power efficiency, allowing for longer gaming sessions.

With the option to have 10 or more cores, the Mali-G720 GPU GPU, based on the same fifth-generation graphics, will be used in mid-range smartphones, while the Mali-G620 GPU is designed for entry-level smartphones, with the option of five or fewer cores.
All of ARM’s new GPUs claim to have approximately 15% better power efficiency, resulting in improved battery life during gaming.
The new CPU and GPU cores are expected to be seen in the coming high-end chipsets from Qualcomm, MediaTek and Samsung.
