We can better compare what are the technical differences between the two processors. The processor Intel Core i7-5960X has a larger number of cores, that the maximum frequency of the Intel Core i7-8700K is superior, that the TDP of the Intel Core i7-8700K is lower. The Intel Core i7-8700K has been launched after.

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 i7-8700K  5 639
 24 711

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 20%. In multi-core, the difference in terms of gap is 18%.

PassMark:

Processeur PassMark – CPU Mark & single thread
Intel Core i7-8700K  2,700
 15,965
Intel Core i7-5960X  1,995
 15,950

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 35% in single-core. On the multi-core side, the gap is 0%.

Cinebench R15:

Processeur Cinebench R15 – Score
Intel Core i7-8700K  194
 1,402
Intel Core i7-5960X  140
 1,393

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 39% in single-core. On the multi-core side, the gap reaches 1%.
