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 i9-9900KS is greater, that the PDT of Intel Core i9-9900KS is lower. The Intel Core i9-9900KS 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 i9-9900KS 220
Intel Core i7-5960X 140

In single core, the difference is 57%. In multi-core, the differential gap is 54%.

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 i9-9900KS 3,110
Intel Core i7-5960X 1,980

In single core, the difference is 57%. In multi-core, the differential gap is 61%.

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.

On Windows 64-bit:

Geekbench 4 - Multi-core & single core score - Windows 64-bit
Intel Core i9-9900KS 6,728
Intel Core i7-5960X 4,683

In single core, the difference is 44%. In multi-core, the differential gap is 27%.

On Linux 64-bit:

Geekbench 4 - Multi-core & single core score - Linux 64-bit
Intel Core i9-9900KS 7,208
Intel Core i7-5960X 4,977

In single core, the difference is 45%. In multi-core, the differential gap is 41%.

On Mac OS X 64-bit:

Geekbench 4 - Multi-core & single core score - Mac OS X 64-bit
Intel Core i9-9900KS 6,522
Intel Core i7-5960X 4,645

In single core, the difference is 40%. In multi-core, the differential gap is 30%.

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