We can better compare what are the technical differences between the two processors. The processor Intel Core i9-11900K has more cores, the maximum frequency of Intel Core i9-11900K is greater, that the thermal dissipation power of Intel Celeron 3867U is less. 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.

CPU-Z - Multi-thread & single thread score
Intel Core i9-11900K#ad 708
Intel Celeron 3867U#ad 194

In single core, the difference is 265%. In multi-core, the differential gap is 1556%.

CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.

Cinebench R15 - Multi-thread & single thread score
Intel Core i9-11900K#ad 245
Intel Celeron 3867U#ad 68

In single core, the difference is 260%. In multi-core, the differential gap is 1585%.

Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.

Cinebench R20 - Multi-thread & single thread score
Intel Core i9-11900K#ad 604
Intel Celeron 3867U#ad 145

In single core, the difference is 317%. In multi-core, the differential gap is 1842%.

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.

PassMark - CPU Mark & single thread
Intel Core i9-11900K#ad 3,754
Intel Celeron 3867U#ad 1,082

In single core, the difference is 247%. In multi-core, the differential gap is 1827%.

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 Windows:

Geekbench 5 - Multi-core & single core score - Windows
Intel Core i9-11900K#ad 1,808
Intel Celeron 3867U#ad 413

In single core, the difference is 338%. In multi-core, the differential gap is 1099%.

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.
