We can better compare what are the technical differences between the two processors. The processor Intel Core i7-11700K has more cores, the maximum frequency of Intel Core i7-11700K is greater, that the thermal dissipation power of Unisoc SC9863 is less. The Intel Core i7-11700K was designed earlier.

Performances :

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

Geekbench 5 - Multi-core & single core score - Windows & Android
Intel Core i7-11700K#ad 1,668
Unisoc SC9863#ad 147

In single core, the difference is 1035%. In multi-core, the differential gap is 1150%.

Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems. Geekbench 5 includes new workloads that represent work tasks and applications that we can find in reality.
