Today MediaTek is asserting a refresh of the Dimensity 800 mid-range SoC – a brand new 5G chipset that had solely been introduced earlier this 12 months at CES. The newer Dimensity 820 enormously improves the CPU efficiency of the chip, provides in an additional GPU core, and improves the ISP’s imaging capabilities with newer high-resolution sensors.

The largest improve on the brand new refreshed SoC is the clock frequencies of its 4 Cortex-A76 efficiency cores, which see a uptick from the unique 2.0GHz frequency as much as a a lot larger 2.6GHz goal on the brand new chipset. That’s fairly a considerable 30% clock uptick for an inter-generational replace like this – which begs the query on whether or not it is a higher binned half, a silicon respin, or outright a design replace over the Dimensity 800.
Notably, MediaTek additionally upgraded the GPU specs of the SoC, now disclosing a Mali-G57MP5, another core than the MP4 configuration of the Dimensity 800. Again, we don’t know if because of this the unique SoC had disabled GPU cores, or if that is an up to date design with an even bigger GPU.
The SoC’s ISP has been upgraded in efficiency to now deal with single digicam sensors as much as 80MP decision, an uptick over the 64MP marketed capabilities of the D800.
As with the entire new “Dimensity” SoC line-up, it’s differentiating function that units it aside from earlier “Helio” SoCs is the truth that it helps 5G connectivity. Here the Dimensity 820, just like the D800 earlier than it, helps all communication requirements from 2G to 5G NR sub-6GHz, solely missing mmWave connectivity (Which given MediaTek’s markets and price-point of this SoC, is smart).
We nonetheless haven’t seen all that many units with the Dimensity 800 – however the newer Dimensity 820 appears to be fairly an even bigger efficiency replace, and we’re anticipating extra distributors to announce new telephones with the SoC within the coming months.
