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, they have a similar turbo frequency, that the thermal dissipation power of Intel Core i9-9900K is less. The Intel Core i7-10700K 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.

On Windows 64-bit:

Geekbench 4 - Multi-core & single core score - Windows 64-bit
Intel Core i9-9900K 6,336
Intel Core i7-10700K 5,994

In single core, the difference is 6%. In multi-core, the difference in terms of gap is 9%.

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.

On Windows:

Geekbench 5 - Multi-core & single core score - Windows
Intel Core i9-9900K 1,324
Intel Core i7-10700K 1,317

In single core, the difference is 1%. In multi-core, the difference in terms of gap is 2%.

Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems. Geekbench 5 includes new workloads that represent work tasks and applications that we can find in reality.
