This time with RAM-OC: Once again, the Ryzen 7 5800X3D faces the Core i7-12700K and i9-12900K in the test, but this time the RAM has been optimized. The “X3D” uses DDR4-3800CL16, the Core i7-12700K relies on DDR4-4000CL16 and the i9-12900K on DDR5-6800CL32. Who will do the race? And at what price?

The author of this article is registered on the ComputerBase forums with the username Esenel and is known for his expertise in the field of RAM-OC. In the community benchmark tests, it usually takes first place – thanks to the faster CPU and GPU, but also because of the RAM settings that have been pushed to the optimum. The processors were made available on loan by the respective companies at the request of the editors.
Again AMD Ryzen X3D vs. Intel Core
AMD Ryzen 7 5800X3D against Intel Core Alder Lake – this duel has already happened several times on ComputerBase. What was still open to date was a comparison at the limit: with overclocked memory and optimized memory timings. This community article catches up.

Why two Intel processors?
At a time when everything is becoming more expensive, it doesn't always have to be the high-priced components. To take this into account, in addition to the Core i9-12900K, an Intel Core i7-12700K paired with 2 × 16 GB G.Skill RipJaws V (DDR4-3200, CL14) will compete against AMD's fastest gaming CPU. A competition that is priced at eye level. The Intel Core i9-12900K with 2 × 16 GB Teamgroup T-Force Delta RGB (DDR5-6400, CL40), which is also represented, serves purely as a reference for the potential of DDR5 and the Alder Lake architecture if you let it run free .
What are the costs?
At the time of writing this article, the AMD Ryzen 7 5800X3D has seen a slight price increase and currently retails for around $489, although you could have it for around $460. An Intel Core i7-12700K is currently around 425 euros, but was also available for less than 400 euros. If you now include the higher mainboard prices of Intel's Z690 in order to be able to overclock the CPU in an emergency, the costs are roughly the same on both sides, depending on the equipment selected.
As the test also shows, one advantage of the AM4 platform is that older mainboards, such as the X470 Crosshair used by Asus, can (usually) be used without any problems. A kit was used for the main memory that can be operated stably at well over 4,000 MHz without much effort in order to rule out a bottleneck at this point and to see how stable the samples used can be operated.

All settings checked for stability
The settings finally used in the test had to face several hours of RAM stability tests before the results were determined. It should be noted here that the processors allowed the working memory to be booted 200 MHz higher, but it was not possible to operate it stably. Both settings also offer the potential to sharpen individual timings, which would have involved a great deal of extra effort and, especially with the Ryzen 7 5800X3D, would have had little or no positive effect on performance, since the large cache largely puts the benefits of fast RAM into perspective .
