We can better compare what are the technical differences between the two processors. The processor Intel Core i7-10700KA has more cores, the maximum frequency of Intel Core i7-10700KA is greater, that the thermal dissipation power of Intel Core i7-5775C is less. The Intel Core i7-10700KA 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
Intel Core i7-10700KA#ad 220
2,005
Intel Core i7-5775C#ad 153
770


In single core, the difference is 44%. In multi-core, the differential gap is 160%.


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 i7-10700KA#ad 3,080

Intel Core i7-5775C#ad 2,280
7,750


In single core, the difference is 35%. In multi-core, the differential gap is 155%.


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.
