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 3950X is greater, that the PDT of AMD Ryzen 9 3950X is lower. The AMD Ryzen 9 3950X 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 3950X 220
Quad AMD Opteron 6276 75

In single core, the difference is 193%. In multi-core, the differential gap is 39%.

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
AMD Ryzen 9 3950X 2,750
Quad AMD Opteron 6276 840

In single core, the difference is 227%. In multi-core, the differential gap is 156%.

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 Linux 64-bit:

Geekbench 4 - Multi-core & single core score - Linux 64-bit
AMD Ryzen 9 3950X 6,227
Quad AMD Opteron 6276 2,159

In single core, the difference is 188%. 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. © 2020 - Privacy policy
