We can better compare what are the technical differences between the two processors. The processor Dual AMD EPYC 7H12 has a larger number of cores, the turbo frequency of Dual AMD EPYC 7H12 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 - Windows & Android
Dual AMD EPYC 7H12#ad 653
MediaTek Dimensity 800U 5G#ad 599

In single core, the difference is 9%. In multi-core, the difference in terms of gap is 516%.

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.
