Dimensity 810 Trims Phone Power

October 5, 2021

Author: Aakash Jani

The new Dimensity 920 and Dimensity 810 bring power and performance upgrades to MediaTek’s midrange-smartphone portfolio. The latter chip boosts the single-thread CPU throughput by double digits compared with the Dimensity 800 while reducing power consumption, and the former delivers targeted gaming improvements. Both are in production. Realme announced its 8s phone would use the D810 and sell to the Indian market for 17,999 rupees ($245). Both Oppo and Honor plan to base their upcoming midrange phones on the D920.

The D810 replaces the D800 and sits a step below the Dimensity 820. It has two Cortex-A76 CPUs and six Cortex-A55 CPUs, differing from the D800’s 4+4 configuration. MediaTek increased the A76’s peak frequency to 2.4GHz, raising peak single-thread performance by 20%, but replacing two big cores with two little ones results in a net downgrade in multicore performance of 17%. The single-thread lift will give gamers better frame rates, but the multicore deficit may jam up background applications.

Earlier this year, MediaTek made major changes to its midrange-smartphone lineup by introducing the Dimensity 900, using Cortex-A78 for the “big” cores and moving from a 4+4 configuration to 2+6. Its midyear refresh, the Dimensity 920, offers more-muted changes. That processor maintains the D900’s CPU configuration while upclocking two of the cores to 2.5GHz. The difference adds 4% to single-thread performance but barely raises multicore performance.
