We can better compare what are the technical differences between the two processors. The processor Dual Intel Xeon Platinum 8280 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 R15 - Multi-thread & single thread score
Dual Intel Xeon Platinum 8280#ad 90
7,193
Intel Core i9-11900K#ad 245
2,140


In single core, the difference is 172%. In multi-core, the difference in terms of gap is 236%.


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
Dual Intel Xeon Platinum 8280#ad 395
18,404
Intel Core i9-11900K#ad 604
5,748


In single core, the difference is 53%. In multi-core, the difference in terms of gap is 220%.


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
Dual Intel Xeon Platinum 8280#ad 2,210
43,940
Intel Core i9-11900K#ad 3,754
28,072


In single core, the difference is 70%. In multi-core, the difference in terms of gap is 57%.


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.
