Welcome to the Intel Core i9 13900k vs Ryzen 9 7950x vs 7900X processor performance comparison .
As you all know, the Intel Core i9-13900K is already a reality. Intel has made the expected disclaimer and here we have tested the performance with some of its most direct rivals, the AMD Ryzen 9 7000. In addition, we will see if the P-Core and E-Core achieve a good balance between performance and consumption as shown. waiting for them.

Benchmark and performance
To test the Intel Core i9-13900K unit and make a comparison with its rivals with the used benchmark is the following:
| TESTING BENCH | |
| Processor: | Intel Core i9-13900K |
| Motherboard : | Asus ROG Maximus Z790 Hero |
| RAM: | 32GB Kingston Fury Beast RGB DDR5 5600MHz |
| heatsink | Corsair H150i ELITE LCD |
| HDD | ADATA Gammix S70 |
| Graphic card | Nvidia RTX 3080 Ti |
| Power supply | Corsair RM1000 |
*The Asus ROG Maximus Z790 Hero board has been configured with a BIOS version 0502 with stock values, using Windows 11 Pro in its latest version for testing and VBS disabled.
Benchmarks (synthetic tests)
The tests we have used are:
- Aida64 (RAM memory)
- Cinebench R23 (CPU Score)
- 3DMARK Fire Strike (DX11) (Physics Score)
- Time Spy (DX12) (Physics Score)
As in the case of Alder Lake vs Zen 4 , memory performance, specifically read and write speeds, have been superior on the Intel as highlighted in the tests carried out with this configuration. Figures that are maintained in all available cores, being a monolithic chip.
In the maximum performance tests of Cinebench R15, an improvement of 52% in multi-core compared to 12900K and 14% in single-core has been obtained . Despite this, the AMD Ryzen 9 7950X remains evenly matched in multi-core and is outclassed in single-core. On the other hand, in the CB-R20 test these measures with respect to the 12900K are 46% and 11% respectively and it surpasses the 7950X by 6% in single-core, although once again it is almost equal in multi-core performance. Finally in CB-R23 it proves to be the most powerful CPU we have tested so far, beating the previous generation 12900K by 48% multi-core, breaking the 2200 point barrier in a single thread.
As for the graphical tests, we have Fire Strike results in DX11 that beat the AMD 7950X by 21% and the 12900K by 40%. However, in tests with DX12 those figures remain at 47% and 24% respectively. These have been the most representative tests.
game testing
We look at the performance of the Intel Core i9-13900K in games at 1080p resolutions , which makes the CPU performance stand out the most against other higher resolutions where the GPU has more to say. Note that the CPU has a large impact at lower game resolutions, as demonstrated below. We set the following settings for each run:
- Shadow of the Tomb Raider, Alto, TAA, DirectX 12
- Far Cry 5,Alto, TAA, DirectX 12
- DOOM Eternal, Ultra, Vulkan
- Final Fantasy XV, standard, TAA, DirectX 11
- Deus EX Mankind Divided, Alto, DirectX 11
- Metro Exodus, Alto, DirectX 12
Looking at the same tests performed on 1444p , the results are as follows:
In 3 of the 6 games tested at 1080p and 2k, the 13900K outperforms other CPUs, but the AMD processor is also in very good positions . Zen 4 processors, when released, may be able to match or exceed the performance of the current Ryzen 7 5800X3D and other CPUs.
Consumption and temperature
The Prime95 test has been used to analyze temperatures and consumption of the Intel Core i9-13900K in different scenarios, monitoring telemetry through HWiNFO and measuring the consumption of the test bench with a wattmeter . The results obtained in this comparison have been:
In this case, less is better.
Final words and conclusions about Intel Core i9 13900k vs Ryzen 9 7950x vs 7900X
The Intel 13900K wins for raw power in all tests, but the AMD Ryzen 7950X is very close and the 7900X a little further. All three options are fantastic, but we still think that the results it offers us in our reviews (take a look), the AMD Ryzen 7000 optimize their consumption better with more power.
