We can better compare what are the technical differences between the two processors. The processor Intel Core i9-10990XE has a larger number of cores, the maximum frequency of Intel Core i9-11900K is greater, that the PDT of Intel Core i9-11900K is lower. The Intel Core i9-11900K was designed earlier.

Performances :

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

Cinebench R20 - Multi-thread & single thread score
Intel Core i9-10990XE#ad 592
Intel Core i9-11900K#ad 604

In single core, the difference is 2%. In multi-core, the difference in terms of gap is 144%.

Cinebench R20 is a multi-platform test software which allows to evaluate the hardware capacities of a device such as a computer, a tablet, a server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant.

On Windows:

Geekbench 5 - Multi-core & single core score - Windows
Intel Core i9-10990XE#ad 1,295
Intel Core i9-11900K#ad 1,808

In single core, the difference is 40%. In multi-core, the difference in terms of gap is 60%.

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.
