Price: prices can change over time. For technical reasons, they are not updated in real time. This is only an average of the results on the first page of each product, whether new or used. Shipping costs have not been integrated. To know the final price of the product, please go to the form of the shop. If no price is indicated, it means that we did not find any offers during the last update.

We can better compare what are the technical differences between the two processors. We see that the two processors have an equivalent number of cores, the maximum frequency of Intel Core i5-7640X is greater, that the thermal dissipation power of Intel Core i7-2600K is less. The Intel Core i5-7640X was designed earlier.

Ratios: we first consider the average for the new price if available, the average for the used price otherwise. Performance / global cost ratio: This is the ratio of performance on Geekbench 4, divided by the cost of the product + the cost of electricity over 5 years for a duration of use of 13 hours per day.

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 i5-7640X 184
716
Intel Core i7-2600K 121
609


In single core, the difference is 52%. In multi-core, the differential gap is 18%.

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 i5-7640X 2,460
9,550
Intel Core i7-2600K 1,940
8,420


In single core, the difference is 27%. In multi-core, the differential gap is 13%.

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.
