We can better compare what are the technical differences between the two processors.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

The processor Unisoc UIS7862 has more cores, the maximum frequency of Unisoc UIS7862 is greater, that the thermal dissipation power of Unisoc UIS8581A is less. The Unisoc UIS7862 was designed earlier.

Performances :


Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.


AnTuTu - Total score
Unisoc UIS7862 87,765
Unisoc UIS8581A 74,462


The difference is 18%.


AnTuTu is one of the most popular apps in the world to evaluate and compare the power of a mobile device with the competition. It tests above all the power of calculation, the display of Web pages, the modeling of decorations in 3D, the management of the memory, the transfer of data.


Android PassMark - CPU Mark
Unisoc UIS7862 2,074
Unisoc UIS8581A 1,507


The difference in performance is 38%.


PassMark is a benchmarking software that performs several performance tests including prime numbers, integers, floating point, compression, physics, extended instructions, encoding, sorting. The higher the score is, the higher is the device capacity.





On Android 64-bit:

Geekbench 4 - Multi-core & single core score - Android 64-bit
Unisoc UIS7862 1,726
5,053
Unisoc UIS8581A 827
3,316


In single core, the difference is 109%. In multi-core, the differential gap is 52%.


Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, images, AES encryption, SQL encoding, HTML, PDF file rendering, matrix computation, Fast Fourier Transform, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these devices. For each result, we took an average of 250 values on the famous benchmark software.


On Android:
