The MediaTek Dimensity 1050 and MediaTek Dimensity 800U 5G are mid-range 5G smartphone processors from different generations of the Dimensity series. The Dimensity 800U 5G, introduced in 2020, combines a 7 nm process with Arm Cortex-A76 CPU cores to deliver balanced performance for everyday use. Introduced in 2022, the Dimensity 1050 moves to a 6 nm process and upgrades to Cortex-A78 CPU cores, a newer Mali-G610 GPU, mmWave 5G support, and updated memory and multimedia features.
General
Both processors integrate 5G connectivity and are manufactured by TSMC, but they target different generations of smartphones. The Dimensity 1050 adopts a newer 6 nm process and adds support for both sub-6GHz and mmWave 5G, while the Dimensity 800U 5G uses a 7 nm process with sub-6GHz 5G support.
