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 AMD Ryzen 9 3900X is greater, that the PDT of AMD Ryzen 9 3900X is lower. The AMD Ryzen 9 3900X 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
AMD Ryzen 9 3900X 205
3,160
Intel Core i9-9920X 188
2,784


In single core, the difference is 9%. In multi-core, the differential gap is 14%.

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.


Cinebench R20 - Multi-thread & single thread score
AMD Ryzen 9 3900X 520
9,170
Intel Core i9-9920X 460
6,030


In single core, the difference is 13%. In multi-core, the differential gap is 52%.

Cinebench R20 is a multi-platform test software which allows to evaluate the hardware capacities of a device such as a computer, a tablet, a server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant.
