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 Samsung Exynos 7 Octa 7420 has a larger number of cores, the maximum frequency of Intel Core i5-6600K is greater, that the thermal dissipation power of Samsung Exynos 7 Octa 7420 is less. Both were produced in the same year.

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.

Geekbench 4 - Multi-core & single core score - Linux & Android 64-bit
Intel Core i5-6600K 5,312
Samsung Exynos 7 Octa 7420 1,356

In single core, the difference is 292%. In multi-core, the differential gap is 268%.

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.
