MediaTek Dimensity 800U
MediaTek's Dimensity 800U is a 7nm 5G chip with two 2.4 GHz Cortex-A76 cores, six 2.0 GHz Cortex-A55 cores and a three-core Mali-G57 GPU. Announced in August 2020, it debuted in China's Realme X7 and also powers phones such as the Realme 7 5G, with dual-SIM 5G and support for 120Hz Full HD+ displays.
Pros
- Two Cortex-A76 cores clocked at 2.4 GHz; MediaTek cites up to 11% faster CPU and 28% faster GPU performance than the Dimensity 700 series
- Dual 5G SIM with dual VoNR and 2CC carrier aggregation, with a peak download of 2.3 Gbps
- Supports 120Hz Full HD+ displays and HDR10+ playback
- Supports LPDDR4X-2133 memory, UFS 2.2 storage and cameras up to 64MP
Cons
- Only two Cortex-A76 cores, so multi-core performance sits below the four-A76 Dimensity 800 and 820
- Three-core Mali-G57 GPU has fewer cores than the Dimensity 800 (four) and 820 (five)
- 5G is sub-6GHz only, Wi-Fi is Wi-Fi 5 and 4K video capture is capped at 30fps
