We can better compare what are the technical differences between the two processors. The processor Intel Core i9-9820X has a larger number of cores, the turbo frequency of Intel Core i9-9820X is bigger, that the PDT of MediaTek Dimensity 800U 5G is lower. The MediaTek Dimensity 800U 5G 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 - Linux & Android
Intel Core i9-9820X#ad 1,113
MediaTek Dimensity 800U 5G#ad 599

In single core, the difference is 86%. In multi-core, the difference in terms of gap is 421%.

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.
