MediaTek Dimensity 800U announced with higher CPU speeds, dual 5G SIM support
After bringing its Dimensity 800 and 820 midrange chipsets, MediaTek has unveiled its third entry in the 800-series with the new Dimensity 800U.
Itâs a slightly tweaked and more affordable version of the Dimensity 800 bringing an integrated 5G modem, dual 5G SIM support (SA & NSA modes) and higher CPU speeds. Itâs built on the same TSMC 7nm process and also comes with dual Voice over New Radio (VoNR), and 5G two carrier aggregation (2CC 5G-CA).
| Dimensity 800 | Dimensity 800U | |
| Process | TSMC 7nm | TSMC 7nm |
| CPU, big cores | 2 x Cortex-A76 @ 2.0GHz | 2 x Cortex-A76 @ 2.4GHz |
| CPU, small cores | 6 x Cortex-A55 @ 2.0GHz | 6 x Cortex-A55 @ 2.0GHz |
| GPU | Mali-G57 MC4 | Mali-G57 MC3 |
| RAM | LPDDR4x, up to 16GB | LPDDR4x, up to 12GB |
| Storage | UFS 2.1 | UFS 2.2 |
| Display | 1080p+, 120Hz | 1080p+, 120Hz |
| 5G | Single SIM | Dual SIM |
| Local wireless | Wi-Fi 5, Bluetooth 5.1 | Wi-Fi 5, Bluetooth 5.1 |
The boosted CPU speeds are for the two Cortex-A76 cores which now clock in at 2.4Ghz compared to 2.0GHz on the Dimensity 800. There are also six Cortex-A55 cores working at 2.0GHz.
On the GPU side, we have the Mali-G57 MC3 while storage is now bumped up to UFS 2.2 speeds. Elsewhere, the 800U supports FHD+ display panels with up to 120Hz refresh rates and up to 64MP camera sensors with 4K video recording at 30FPS.
