It’s 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. It’s 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).

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.
Dimensity 800 has 2 cortex A76 cores, not 4.
Dimensity 800 has 4xa76 cores while this new 800u only has 2xa76 cores. In terms of cpu and gpu powers its a downgrade soc but with new features.
Looks much better than Dimensity 800 but I think the price of these Mediatek processors could be same.
