MediaTek Dimensity 820:

Over the last few years, MediaTek is leading in the mobiles chip market, but in 2020 the company has gone so far with record-breaking new chipsets. We’ve seen some amazing chipsets like MediaTek Dimensity 1100, MediaTek Dimensity 9000 which tops the AnTuTu 9 benchmarks, and MediaTek Dimensity 1200 which was launched in XIAOMI 11T and many more smartphones. Now we have the full specs and full complete details of the MediaTek Dimensity 820, let’s start off with the benchmarks.

AnTuTu 9:

CPU 122740
GPU 140736
Memory 70356
UX 115848
Total score 452320

MediaTek Dimensity 820 shows the best AnTuTu 9 scores. We can see the big jump in the GPU performance. The total performance of the GPU is 140736, which is slower than the Snapdragon 778G. The CPU also shows one of the best scores. It is 122740 which is a bit slower than the Snapdragon 778G. The memory scores also show a significant boost. MediaTek Dimensity 820 memory is faster than Snapdragon 765G, Snapdragon 768G. The Ux is also showing one of the best performances. It is 115848, which is faster than Snapdragon 765G, and Snapdragon 768G. Qualcomm Snapdragon 778G total scores are above 452320. It will depend on which smartphones manufacturers using this chipset with which type of ram. Dimensity 820 is considerably gaining a performance boost and beating every processor in the Mid-rand category.

Geekbench 5:

Single-Core Score 525
Multi-Core Score 2398

The single-core scores show the best performance in this smartphone mid-range category lineup. The single-core scores are 525. And the multi-core scores are 2398 which is also good at this point.


Architecture 4x 2.6 GHz – Cortex-A76
4x 2 GHz – Cortex-A55
Cores 8
Frequency 2600 MHz
Instruction set ARMv8.3-A
Process 7 nanometers
TDP 10 W

MediaTek Dimensity 820 lunched with the Big 4 cores of Cortex-A76 which are ultra-high performance cores that are clocked on 2.6 GHz. The other 4 cores are based on Cortex-A55 which is a power efficiency core. There is a little disappointment that why they haven’t used the Cortex X1 or X2. But the Cortex-A76 also has the best speeds and good set instruction architecture. There are a total of 8 cores with a boost clock of 2.6 GHz. MediaTek Dimensity 820 has the latest set instruction architecture. It’s not fast but it is strong enough to beat some of the latest and most powerful Chipsets. Dimensity 820 is fabricated on 7Nm. This means MediaTek Dimensity 820 will be power efficient and will consume less battery and will produce less heat. The TDP shows 10wats which uses more power. This means it will consume more battery and will produce heat.


GPU name Mali-G57 MC5
Architecture Valhall
GPU frequency 650 MHz
Execution units 5
Shading units 80
Vulkan version 1.1
OpenCL version 2.0
DirectX version 12

MediaTek Dimensity 820 has a new architecture-based GPU. Valhall is the new architecture that they are using in Dimensity 820. The GPU is also manufactured using the 7Nm technology. Which means it will also be power efficient. The name of the GPU is Mali-G57 MC5. This is the fastest GPU in this lineup. The MediaTek Dimensity 820 is fast enough to handle games like FREE FIRE and PUBG MOBILE. The GPU score is faster than the Dimensity 820 which means there will be a smooth gaming experience on this chipset. The GPU is clocked on 650MHz. The shading units are also 80 which will help in rendering the graphics in gaming. There is also DirectX support of 12 which means this processor will support the latest games without any bugs and delays.


Memory type LPDDR4X
Memory frequency 2133 MHz
Bus 2x 16 Bit
Max bandwidth 17.07 Gbit/s
Max size 16 GB

MediaTek Dimensity 820 uses the new LPDDR4x ram with the memory frequency of 2133MHz and uses the bus of 2×16. The ram may be changed according to the smartphone manufacturers, like XIAOMI, REALME, VIVO, etc. The memory frequency is also going to be changed according to the smartphone manufacturers. The max memory bandwidth is 17.07Gbit/s which is also faster than the Qualcomm Snapdragon 765G which was used in Oneplus Nord. The max ram support on this chipset is 16GB.


Neural processor (NPU) Yes
Storage type UFS 2.2
Max display resolution 2520 x 1080
Max camera resolution 1x 80MP, 2x 32MP
Video capture 4K at 30FPS
Video playback 4K at 30FPS

MediaTek Dimensity 820 uses its own neural engine which is fast with the AI calculations. MediaTek Dimensity 820 uses the UFS 3.1 which is fast. This gives you fast read and writing speeds.

MediaTek Dimensity 820 has the maximum display support of FullHD+ and can support the 120Hz refresh rate with the super Amoled. Dimensity 820 is going to be very aggressive when it comes to a camera support. It supports a camera of up to 80MP. The video capture is kept on 4k at 30FPS and the video playback is also 4k at 30FPS. There is no 8k support on this MediaTek Dimensity 820. It is a bit odd to see no 8k support on a 2021 mid-range Chipset.


5G support Yes
Wi-Fi 5
Bluetooth 5.1

MediaTek Dimensity 820 has 5G support. The MediaTek Dimensity 820 also comes with wi-fi 6 and the Bluetooth version of 5.1. This will give you better signals and better speeds. MediaTek Dimensity 820 uses its own 5G modem. It is not fast as the X65 but it gives you good speeds.


Phones with Dimensity 820 AnTuTu v9
1. Xiaomi Redmi 10X Pro 5G 456378
2. Xiaomi Redmi 10X 5G 452320

MediaTek Dimensity 820 is launched in these 2 smartphones. As you can see these 2 smartphone scores are different. Xiaomi Redmi 10X Pro 5G is at the top. Which is a considerably great phone with this chipset.

Gaming Experience:

PUBG Mobile 46 FPS
Call of Duty: Mobile 41 FPS
Fortnite 28 FPS
Shadowgun Legends 52 FPS
World of Tanks Blitz 55 FPS
Genshin Impact 35 FPS
Mobile Legends: Bang Bang 58 FPS
Device Xiaomi Redmi 10X Pro
1080 x 2400

The gaming experience on this chipset is going to be a little faster than the MediaTek Dimensity 820. This chipset is combined with the 4 Big A76 cores which boost the performance. With 4 big Cortex A-76 cores, there are also going to be a few issues with heating. The frequency of this chipset is 2.6 GHz, which is good for long-term gaming. This chipset also supports the LPDDR4x ram. This means there will be no issues with using this chipset in a long-term gaming session. This chipset also supports a 120Hz refresh rate. This will help in smooth performance with low latency. This chipset is can support PUBG MOBILE at 60FPS, this is because of the scores of the GPU.
