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 Core 2 Quad Q9550 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

6,443
Intel Core 2 Quad Q9550#ad 238
976


In single core, the difference is 197%. In multi-core, the differential gap is 560%.


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
2,140
Intel Core 2 Quad Q9550#ad 74
320


In single core, the difference is 231%. In multi-core, the differential gap is 569%.


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
28,072
Intel Core 2 Quad Q9550#ad 1,220
2,250


In single core, the difference is 208%. In multi-core, the differential gap is 1148%.


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.
