Exynos 1080 Doubles GPU Throughput

December 24, 2020

Author: Aakash Jani

The Exynos 1080 is an annual refresh of Samsung’s mid-premium smartphone SoC, boosting performance across the board. It delivers these upgrades in a power envelope similar to that of the older Exynos 980 by shifting to the company’s 5nm LP technology. The changes continue to blur the lines between premium and mid-premium smartphones. The 1080 will appear in the Vivo X60, which is scheduled to launch by year-end. We estimate the phone, which employs a Samsung super-AMOLED 120Hz display, will sell for $535.

Last year’s 980 provides two 2.2GHz Cortex-A77s and six 1.8GHz Cortex-A55s, forgoing the prime-core arrangement. Samsung moved to a more premium configuration for the 1080 by integrating four Cortex-A78s, three running at 2.6GHz and one at 2.8GHz, and four 2.0GHz Cortex-A55s. Arm claims the A78 delivers 20% more performance than the A77 in the same power envelope.

The shift to 5nm lifted frequencies across the board to help drive performance gains. The “little” A55 cores operate 11% faster, the “big” A78 cores operate 18% faster, and the prime A78 core operates 27% faster. Accounting for the frequency and IPC upgrades, we estimate the 1080 outpaces its predecessor by 53% in single core-performance and 78% in multicore performance.
