Today MediaTek is announcing a refresh of the Dimensity 800 mid-range SoC – a new 5G chipset that had only been announced earlier this year at CES. The newer Dimensity 820 greatly improves the CPU performance of the chip, adds in an extra GPU core, and improves the ISP’s imaging capabilities with newer high-resolution sensors.

The biggest upgrade on the new refreshed SoC is the clock frequencies of its four Cortex-A76 performance cores, which see a uptick from the original 2.0GHz frequency up to a much higher 2.6GHz target on the new chipset. That’s quite a substantial 30% clock uptick for an inter-generational update like this – which begs the question on whether this is a better binned part, a silicon respin, or outright a design update over the Dimensity 800.
Notably, MediaTek also upgraded the GPU specifications of the SoC, now disclosing a Mali-G57MP5, one more core than the MP4 configuration of the Dimensity 800. Again, we don’t know if this means that the original SoC had disabled GPU cores, or if this is an updated design with a bigger GPU.
The SoC’s ISP has been upgraded in performance to now handle single camera sensors up to 80MP resolution, an uptick over the 64MP advertised capabilities of the D800.
As with the whole new “Dimensity” SoC line-up, it’s differentiating feature that sets it apart from previous “Helio” SoCs is the fact that it supports 5G connectivity. Here the Dimensity 820, like the D800 before it, supports all communication standards from 2G to 5G NR sub-6GHz, only lacking mmWave connectivity (Which given MediaTek’s markets and price-point of this SoC, makes sense).
We still haven’t seen all that many devices with the Dimensity 800 – but the newer Dimensity 820 seems to be quite a bigger performance update, and we’re expecting more vendors to announce new phones with the SoC in the coming months.

This midrange chip will probably show up on USD $300 devices.Yet, it looks like it will outcompete against a USD $1,200 Samsung Galaxy Note 20, with its lacklustre Exynos 990 chipset.
It's refreshing to see these "midrange" SoC's finally surpass the performance of the old flasgship chipsets like the QSD 835 and QSD 845. Though the QSD 855 and QSD 865 are still top-tier for now in the Android Ecosystem.
Though I'm more curious about the major (or minor) improvements coming this year to the Apple A14 and A14Z to power the next iPhone and iBook, as rumoured.

erynos is trying to chase a bit to many rabbits at same time.They try to replace gpu inside with rdna from AMD with ~400% gain, integrate stuff, but keep separate modules as option etc.....
That's why it takes performance hit.

The performance gain will be too high compared to any chip Qualcomm will have, so how exactly will samsung try to sell the next galaxy phone in north America with a much slower GPU while the international model will have the amd gpu?iphonebestgamephone - Wednesday, May 20, 2020 - link
None knows the power usage of that leaked chip's benchmarks. And its not like qualcomm will just sit there forever.iphonebestgamephone - Wednesday, May 20, 2020 - link
The gpu of this thing would be really weak compared to 845, even the 1000l is worse. Though it is a lot more efficient.boozed - Monday, May 18, 2020 - link
How much cheating does this one include?eastcoast_pete - Tuesday, May 19, 2020 - link
Now I know that it's hard (for good reasons!) to trademark numbers, but why would they use one that's associated with a older Snapdragon? Pretty sure some well-paid lawyer at Qualcomm spent some hours looking into this.iphonebestgamephone - Wednesday, May 20, 2020 - link
Kirin did the same with 810.JulianaJP - Tuesday, August 11, 2020 - link
