The release of the RTX 3080 Ti is probably the most exciting Ti upgrade in Nvidia’s lineup because it’s almost as powerful as the RTX 3090. However, being considerably ahead of the RTX 3080 in terms of performance means that you’ll need to pair the 3080 Ti with a CPU that performs just as well without creating a bottleneck. Therefore, we have carefully selected this list of the best CPUs for RTX 3080 Ti.
Once you compare the specifications of the RTX 3080 Ti to the 3080 in more detail, you’ll notice that it’s going to be around 13% more powerful. In fact, it’s barely behind Nvidia’s behemoth, the RTX 3090, by around 4%. The RTX 3080 Ti has more GPU cores, tensor cores, RT cores, as well as VRAM than its smaller brother, so naturally, we’ll need an adequate CPU that can match this performance increase.
If you want to get a smoother 1440p or 4K gaming experience and utilize more computationally demanding software, you can match the RTX 3080 Ti with one of the CPUs listed below depending on your needs.
Best CPUs for RTX 3080 Ti

AMD’s 5900X is an enthusiast-grade CPU that is fantastic for a stable 4K gaming experience as well as performing demanding tasks, like content creation, rendering, and so on. In fact, with 12 cores and an achievable boost frequency of 4.8GHz, this processor won’t even reach its maximum capability in games. That said, the 5900X blows most of the competition out of the water. Compared to what Intel has to offer, this CPU comes with a much larger 70MB cache. Its architecture is also superior and it only requires 105W of power. That’s impressive for such a high core count and frequency.
As mentioned, the 5900X is not made for the average gamer. If you plan to game at 1080p or even 1440p only, this model is probably overkill. You can opt for a 5800X or even a 5600X and you won’t feel much of a difference. However, if you work with computationally demanding software, the 5900X is hard to beat, especially for its price. It’s also future-proof, so if you buy it together with an RTX 3080 Ti, your system will be fairly cutting edge for several years.
The 11900K is a single-core powerhouse, but it has 2 cores less than the previous generation and high power requirements. Nevertheless, it is still a powerful CPU and a great pair for the RTX 3080 Ti.

Remember that games still don’t take full advantage of multi-core processing. That is why the 5600X, which is significantly cheaper, is just as good as the 5800X when it comes to gaming. The difference is marginal.
Unfortunately, AMD disappointed fans of mid-range setups by not including their famous Wraith Prism cooler with this Ryzen 7 generation. Only CPUs with a TDP lower than 65W come with it these days. So, if you choose the 5800X instead of the 5600X you’ll have to keep that in mind.
The Ryzen 7 5800X is overall a good CPU for most RTX 3080 Ti. If you’re a 4K gamer, you don’t really need anything above it in terms of performance. However, it performs extremely well in demanding applications thanks to its powerful 8 cores. So, if you’re also a content creator looking for something decent for rendering, the 5800X is a good option. Only go a step higher with the 5900X if you want to save time.
5Intel Core i7-11700K
If you want to stick to Intel processors for gaming, the 11700K is powerful thanks to its single-core performance. However, when you consider the price and multithreaded performance, there are better options.
