The NVIDIA RTX 4080 delivers high-end performance for 1440p and 4K gaming in nearly all recent titles.
Class-leading DLSS and Ray Tracing performance will cause some buyers to choose this GPU, which is understandable. But because it has so much power at its disposal, you need to use it with a powerful processor to guarantee good frame rates and maximize the performance of the $1000 Ampere-powered GPU.
To get the most of this potential capability, we recommend combining the GPU with a processor that is as powerful. Some of the remarkable chips made by AMD and Intel are specifically made for gaming.
In this article, you will learn about the 5 best CPUs for the RTX 4080 in 2023.
5 Best CPUs for the RTX 4080
1. Intel Core i5-13600K
Intel’s Core i5-13600K takes the spotlight as our top pick for the best budget option to pair with the RTX 4080.
While it might seem unconventional to label an i5 as a ‘budget’ choice, the exceptional performance of Intel’s 13th generation lineup allows for this remarkable pairing.
The i5-13600K has impressive core and thread counts, high clock speeds, and overall specifications that make it more than capable of handling 4K gaming with the RTX 4080.

Surprisingly, the Core i5-13600K outperforms the Core i9-12900K in single-threaded benchmarks and positions itself between AMD’s Ryzen 9 5900X and 5950X in multi-threaded performance. This versatility extends its usability as a cost-effective option for low-end workstation tasks, including video editing.
The affordability of this CPU adds to its appeal, allowing for a reasonably priced system build with a choice between 12th and 13th Gen motherboards and support for DDR4 and DDR5 RAM. In summary, the Core i5-13600K stands out as the best budget CPU for the RTX 4080.
Perhaps the only downside of the i5-13600K is the performance of its own bigger brothers, the i7-13700K and i9-13900K. These higher-end chips are compelling, and the extra cost for each step up in the Core processor lineup is certainly appealing for those seeking additional performance with a slightly higher budget.
Pros

Factors to Consider When Choosing a CPU for RTX 4080
Let’s delve into critical factors to consider before selecting a CPU to pair with an RTX 4080. We’ve outlined the most crucial considerations below:
1. Motherboard Compatibility
Choosing a compatible motherboard stands out as one of the most critical considerations. It determines the functionality of your build. Look for a motherboard with additional usability features such as PCI-E armor. This feature minimizes potential damage to your PCI-Express pins, especially in scenarios of GPU sag. While this might not be a common issue with most boards, the substantial weight of these new GPUs warrants a comprehensive approach to safeguarding your components.
2. Motherboard Form Factors
Consider the form factor of your motherboard. Ensure it aligns with your case size and build requirements. Different motherboards follow specific form factors like ATX, micro-ATX, and mini-ITX. Select one that fits seamlessly into your chosen PC case.
3. Platform Longevity
One somewhat complex element to consider is the lifespan of the CPU platform you are employing. Essentially, this comes down to: Can you improve performance by upgrading your CPU on the same platform? Should the response be unfavourable you may want to reevaluate your choices.
The main drawback of the RTX 4080 and 4090 GPUs is that they are essentially too good. Because the graphics card is so fast, the CPU sometimes becomes the bottleneck for the GPU when it comes to frame output. Because of this, a build that prioritises CPU agreeability may seem especially appealing.
