We can better compare what are the technical differences between the two processors. The processor Intel Core i7-5960X has more cores, that the turbo frequency of the Intel Core i7-5775C is bigger, that the heat dissipation power of the Intel Core i7-5775C is smaller. The Intel Core i7-5775C was launched more recently.

Note: prices can change over time. They are not updated regularly. Shipping costs have not been integrated.

Performance comparison between the two processors, for this we consider the following benchmarking softwares: Geekbench 4, PassMark and Cinebench R15.

Geekbench 4:

Processeur Geekbench 4 – Score multi-core & single-core – Windows 64-bit
Intel Core i7-5960X  4 683
 29 083
Intel Core i7-5775C  4 884
 16 278

Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, image encryption, AES encryption, SQL encoding, HTML rendering, PDF rendering, Matrix calculation, Fast Fourier Transformation, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these two chips. For each result, we took an average of 250 values on the famous benchmark software.

On the single-core side, the difference is 4%. In multi-core, the differential gap is 79%.


Processeur PassMark – CPU Mark & single thread
Intel Core i7-5960X  1,995
Intel Core i7-5775C  2,225

PassMark is a benchmarking software that performs several tests including prime numbers, integers, floating point, compression, physics, extended instructions, encryption, sorting. Higher is the score, bigger is the power of the computer.

On PassMark, there is a difference of 12% in single-core. On the multi-core side, the gap is 45%.

Cinebench R15:

Processeur Cinebench R15 – Score
Intel Core i7-5960X  140
Intel Core i7-5775C  153

Cinebench R15 allows to evaluate the performance of a CPU by rendering a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, antialiasing, uses sharp and fuzzy reflections, bright areas, procedural shaders, shadows, etc. Faster is the rendering of the scene created, more powerful is the PC, with a high number of points.

On this software, there is a difference of 9% in single-core. On the multi-core side, the gap reaches 81%.
