COMPARISON: Unisoc SC9863A Vs all current SoCs

Today we present our usual comparison for the SoC Unisoc SC9863A against the rest of SoCs on the current market used in tablets. This SoC is an Octa Core model with 8 ARM Cortex-A55 processors in two clusters and a PowerVR IMG8322 GPU, at the VPU level we have native support for H.264 and H.265 video up to 1080p. A chip intended for low-end tablets that within its sector that faces against the options of Mediatek, Qualcomm and Huawei.


Testing hardware

The Teclast P80X includes a chip as a motor Unisoc SC9863A an Octa Core, with 2GB RAM and 16GB of storage memory that we can expand thanks to the included microSD card reader. It has a screen of 8 inch IPS with a resolution of 1280×800 pixels that includes in its upper part a 0.3MP camera with microphone that complements the rear 2MP with flash. We also have WiFi b / g / n, Bluetooth 4.1, GPS, FM Radio, battery 4200 mAh and a 4G-LTE Multiband modem with Dual SIM tray. Finally in the connectivity section we have a 3.5mm audio jack and a microUSB OTG port for data and battery recharging.

General specifications

The SoC Unisoc SC9863A is the entry-level chip used in several western mobiles and that is now trying to gain a foothold in the tablet sector, this SoC has a configuration Octa Core made in 28nm with 4 processors ARM Cortex-A55 in two clusters. In the graphic section we have a GPU PowerVR IMG8322 with display stand FullHD + 2160 × 1080, dual 16MP + 5MP cameras with Full HD video, eMMC 5.1 compatibility and LPDDR3 or LPDDR4 / 4X RAM.


The new SoC Unisoc SC9863A Octa Core has ARM cores Cortex-A55 divided into two clusters, one that stays at 1.2GHz and the other that reaches up to 1.6GHz. An SoC made in 28nm HPC+ which leaves it in the mid-range in terms of consumption / thermals.

  • As we can see, the system supports only ABI armeabi-v8a which allows us to install 64bit apps


For the graphic section we have a GPU PowerVR IMG8322 that has hardware support for OpenGL ES 3.2 and also Vulkan 1.1 but this is not activated in the firmware. We also have OpenCL 1.2 and Android NN HAL support for artificial intelligence. With this GPU we can play basic titles and PUBG in low settings with few frames.


The Unisoc SC9863A we do not know that VPU It mounts exactly but from the data provided by the processor in general we can know that it is very basic, something that we will verify in the tests. Theoretically, it only supports video up to 1080p in the codecs h.265 y h264 and it can also support VP8 but not VP9 natively.

Android system

The system that we find in this first tablet is based on Android 9 Pie (API 28) with support for 64bit apps, the core that controls the system is the kernel 4.4.147 and with compilation date 2019-07-10, a fairly modern version that adopts the advantages of this type of kernel.


We perform several performance tests with the SoCs Unisoc SC9863A, we VS them against powerful SoCs like Kirin 960, Snapdragon 450, Snapdragon 660 and Mediatek SoC in various ranges.


Possibly the best known test, we use the version 6 for historical compatibility. With this test we get an idea of ​​the general performance of the device and we can buy it with others. This test is highly influenced by the internal storage and other general performance values, as we can see in the results of this new SoC outperforms Mediatek MT8163 and Snapdragon 435 that only mount Cortex-A53 cores.


A test that gives us very interesting values ​​of the raw CPU power in mono core and in multi core in addition to the GPU computing. As we see in the results, they indicate a substantial improvement over Cortex-A53 cores and greater efficiency in multicore.


The test of graphics performance par excellence with a fairly solid continuity in terms of results and that helps us when it comes to comparing the performance of GPUs historically. How we see the GPU PowerVR IMG8322 it has a fairly basic performance and only outperforms the lower ranges of other manufacturers.


This test gives us an idea of ​​the desktop application level power of this hardware performing tasks such as video editing, handling text or audio files, something that is increasingly used on Android. The result is a sum of all these aspects and is influenced by the general hardware components. The results are pretty good and vastly outperforms other SoCs in the same industry thanks to multicore performance.

VPU and Sound

We passed a series of performance tests at the video playback level in the Unisoc SC9863A to test all the formats that your VPU, as we can see the results are quite limited and we recommend staying in content 1080p, we can only see 4K in format h.264 with limitations. With the lack of support VP9 we only carry 720p and youtube.

  • Picture quality: Correct colors and acceptable processing.
  • HDR compatibility: No.
  • HDMI-CEC y Auto framerate: Not available when targeting tablets or smartphones.
  • Sound: By default with the firmware it supports stereo only / No certificates.

The SoC Unisoc SC9863A Octa core As we can see in the results of the tests it struggles in the low range offering something interesting for the price. Somewhat higher raw performance thanks to cores Cortex-A55, some cores with a significant mono core improvement compared to the Cortex-A53 and quite superior in multicore. At the level of graphics power the GPU PowerVR IMG8322 it has a fairly fair performance although it allows us to play PUBG in low settings; where it lacks is in its VPU decoding support quite limited in modern codecs.

With the Unisoc SC9863A we are facing an interesting SoC for the low range where we have the latest system Android 9 Pie which gives us some long-term shelf life. In terms of battery life using this processors, we recommend seeing the next review of the Teclast P80X tablet, the data may surprise.
