Introducing Dimensity 800, Mediatek’s new mid-range chipset with built-in 5G modem
To check the features and capabilities of Mediatek’s new processing chipset, it is better to compare it next to Dimensity 1000 and its most important competitor, Snapdragon 765G. The table below shows the key specifications of these three processors side by side.
Communication ways: 5G sub-6GHz
Certainly, the most important feature to mention regarding Dimensity 800 belongs to its internal support of 5G networks, which makes this chipset next to examples such as Snapdragon 765/765G and Kirin 990 5G and flagships like Snapdragon 865 and Exynos 990 that need to connect an external 5G modem to do this. Apart from saving the size of the chipset, this option also seems important in terms of energy consumption (at least on paper). Like its direct competitor, Dimensity 800 will be manufactured with 7nm lithography, although it has not yet been determined whether it will be manufactured by TSMC or Samsung. The communication modem of this chipset supports 5G networks below 6 GHz in both NSA and SA modes with dual carrier aggregation (2CC CA), the latter providing up to 30% wider high-speed coverage, according to MediaTek.
Dimensity 800 has no problem with non-5G communications and it accepts communication with lower generations, from 2G and 3G to 4G. Support for Dynamic Spectrum Sharing or DSS, Voice over New Radio or VoNR option and lastly very low energy consumption are other things worth mentioning in the radio communication section of this chipset.
Processing cores: Cortex-A76+A55
While all three main players in the world of mobile processing in the Android category, namely Qualcomm, Huawei and Samsung, have all moved towards three-cluster structures in their processors, and apart from high-level cores (Performance Cores) and low-level cores, They have also included mid-range processors in their new designs, MediaTek still uses the same classic two-cluster structure that it used before in Dimensity 1000. In the processing part of Dimensity 800, four ARM Cortex-A76 cores at a frequency of 2 GHz are used in the stronger cluster and 4 Cortex-A55 cores with the same frequency of up to 2 GHz are used in the lower cluster, which, despite the same type of cores, is a different story altogether. compared to Snadragon 765.
In Snapdragon 765, 1 Cortex-A76 core with a frequency of 2.3 GHz (2.4 GHz in the G version) is used in the first cluster and another core of the same type with a frequency of 2.2 GHz is located in the second cluster. Finally, in the lowest category, we find 6 1.8 GHz Cortex-A55 cores. SD765 has an advantage over its competitor in the higher frequency of A76 cores, but on the other hand, double the number of A76 cores in Dimensity 800 gives Mediatek the upper hand in things such as the time of running games and multi-threaded processing. Not using new cores Cortex-A77 Meanwhile, it reduces a little of the initial appeal of Dimensity 800, but paying attention to the user category of this chipset on the one hand and not being used Of these cores in the main competitor of this processor, the necessity of this upgrade appears less.
Graphics: Quad-core Valhall
In the graphic part of this collection, Mali-G57MP4 is apparently used with an unannounced frequency, which is lower than Mali-G77MP9 present in Dimensity 1000, but it still belongs to the Valhall family and can be compared with Adreno 620 is present in SD765.
AI: Processing 2.4 trillion operations per second
The artificial intelligence unit or APU 3.0 present in Dimensity 800 consists of four cores in three different types, which provides the possibility of processing 2.4 trillion artificial intelligence operations per second. For comparison, it is enough to know that this figure for Snapdragon 765G by Qualcomm is equal to 5.5 trillion operations per second.
ISP: 64MP single camera
According to the manufacturer, the image signal processor or ISP in Dimensity 800 is at the flagship level and supports four cameras simultaneously. This ISP supports a single camera up to 64 megapixel resolution and dual cameras up to 16 + 32 megapixel resolution, and according to Mediatek, improvements related to artificial intelligence including autofocus, automatic exposure, automatic white balance, noise reduction, HDR and face recognition technology are also included. All of them are at the level of flagship chipsets.
Dimensity 800 supports screens with a maximum resolution of Full HD+ with a refresh rate of 90 Hz, which seems to be an acceptable and advanced possibility for mid-range devices and promises a new experience in the next generation of mid-range phones.
MediaTek stated that the first smartphones equipped with Dimensity 800 will be available in the first half of 2020, but more details about the first devices equipped with this processor have not yet been published.
