How does the Exynos 1480 chipset in the A55 improve its performance compared to the Exynos 1380 in the A35

Manufacturing Process and Architecture

- Process Technology: The Exynos 1480 is built on a 4nm EUV process, while the Exynos 1380 uses a 5nm process. This smaller process allows for better power efficiency and performance improvements[1][3].

- CPU Configuration: The Exynos 1480 features a more advanced CPU architecture with 4 Cortex-A78 cores clocked at 2.75 GHz and 4 Cortex-A55 cores at 2.0 GHz. In contrast, the Exynos 1380 has 4 Cortex-A78 cores at 2.4 GHz and 4 Cortex-A55 cores at 2.0 GHz. This results in a higher clock speed for the performance cores in the A55, enhancing its computational power[1][3][4].

Graphics Performance

- GPU Upgrade: The A55's Exynos 1480 includes the Xclipse 530 GPU, co-developed with AMD and based on the RDNA 2 architecture. This is a significant upgrade from the Mali-G68 MP5 GPU in the A35. The Xclipse 530 provides up to 53% faster GPU performance, particularly beneficial for gaming and graphics-intensive applications[1][3][4].

Benchmark Performance

- CPU and GPU Benchmarks: In benchmark tests, the Exynos 1480 shows about a 14% improvement in CPU performance and a 20% increase in overall performance compared to the Exynos 1380. In GPU-heavy tasks, the A55 outperforms the A35 by nearly 40%, as evidenced by scores in tests like 3DMark Wild Life[1][2][5].

Thermal Management

- Thermal Efficiency: The Exynos 1480 demonstrates better thermal management, maintaining performance during prolonged workloads without significant throttling. In contrast, the Exynos 1380 experiences some performance dips under heavy load, indicating less effective thermal control[1][5].

Conclusion

Overall, the Exynos 1480 in the Galaxy A55 provides enhanced performance, improved graphics capabilities, and better thermal management compared to the Exynos 1380 in the Galaxy A35. These advancements make the A55 a more capable device for multitasking, gaming, and handling demanding applications.
