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. The processor Intel Core i9-9900KS has more cores, the maximum frequency of Intel Core i9-9900KS is greater, that the thermal dissipation power of Intel Core i7-8750H is less. 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 i7-8750H 174

In single core, the difference is 26%. In multi-core, the differential gap is 86%.

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 i7-8750H 2,350

In single core, the difference is 32%. In multi-core, the differential gap is 93%.

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 i7-8750H 4,428

In single core, the difference is 52%. In multi-core, the differential gap is 110%.

On Linux 64-bit:

Geekbench 4 - Multi-core & single core score - Linux 64-bit
Intel Core i9-9900KS 7,208
Intel Core i7-8750H 5,034

In single core, the difference is 43%. In multi-core, the differential gap is 130%.

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 i7-8750H 4,970

In single core, the difference is 31%. In multi-core, the differential gap is 79%.

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.
