We can better compare what are the technical differences between the two processors. The processor Dual AMD Opteron 6276 has a larger number of cores, the maximum frequency of Intel Core i9-11900K is greater, that the thermal dissipation power of Dual AMD Opteron 6276 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
Dual AMD Opteron 6276#ad 140

In single core, the difference is 406%. In multi-core, the differential gap is 63%.

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
Dual AMD Opteron 6276#ad 75
Intel Core i9-11900K#ad 245

In single core, the difference is 227%. In multi-core, the difference in terms of gap is 17%.

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.

PassMark - CPU Mark & single thread
Intel Core i9-11900K#ad 3,754
Dual AMD Opteron 6276#ad 840

In single core, the difference is 347%. In multi-core, the differential gap is 178%.

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.
