The RTX 3080 is a great GPU for gamers who want to play games on high settings. In this article, we will discuss the best CPUs that you can use with your RTX 3080.

The rtx 3080 bottleneck calculator is a tool that allows users to find out the best CPUs for their RTX 3080.

Nvidia’s Ampere RTX 3080 succeeds the Turing RTX 2080 from the previous generation, and although we’ve seen that new-gen GPUs are typically 10-20% faster than previous-gen GPUs, the RTX 3080 takes a commanding lead, outperforming the RTX 2080 by a wide margin.


Specs for the RTX 3080 (FE):-

8704 Boost Cuda Cores Memory: 10GB GDDR6X Memory Speed: 19.5Gbps Clock: 1.71GHz 320-bit memory interface TDP (thermal design power): 320W

According to the official test video from Nvidia Geforce, the RTX 3080 outperforms the RTX 2080 Ti in 4K Doom Eternal gaming by approximately 60% at nearly half the price. This makes picking the proper CPU even more crucial, since you can’t simply go with any quad-core processor and assume that most games aren’t CPU-intensive.

There are games that can now easily use 6 cores, and it has been shown in many studies that having more cores and higher core frequencies affects the frame rate. Fortunately, we have a handful of good CPUs that won’t slow down even a powerful GPU like the RTX 3080 or RTX 3090.

Take a look at what we suggest for the best 4K gaming experience.

Intel Core i5 10600K

While the Ryzen 5 3600 offers greater value for money, the i5 10600K outperforms it in single and multi-threaded performance. It supports high-end graphics cards better than the i5 9600K and offers no slowdown in any game.

It features a 4.1GHz core base clock and a 4.8GHz boost clock, which is the fastest of any i5 we’ve seen. With 6 cores and 12 threads, you should be able to play any AAA games without seeing any significant performance drops in high-intensive regions. If you’re going to use the RTX 3080 with this CPU, you should never go lower than this.

Also, since it does not come with a standard heatsink, you need invest in a decent CPU cooler. Take a look at our suggested Z490 motherboards for even greater performance, which will help you improve your framerates in games as well as the speed of other activities.

AMD Ryzen 7 3700X

AMD’s Ryzen 3rd gen series competed effectively with Intel’s 9th gen CPUs, but the 10th gen pushed ahead with more cores and superior technologies. The problem is, Ryzen 3rd gen CPUs are now cheaper than they’ve ever been. The Ryzen 7 3700X, which competes with Intel’s i7 CPUs, is now priced at the same level as, if not cheaper than, the i5 10600K.

However, it has 8 cores and 16 threads, which will optimize the advantages and assist content producers speed up the process. It also has a factory RGB Wraith Prism cooling that isn’t as bad as Intel’s standard heatsink.

The processor has a 3.6GHz core clock and a 4.4GHz boost clock. When compared to the i5 10600K, it loses just 5-7 percent of the time, and in certain games, the difference is as little as 1%, making it a worthy and even better option for the RTX 3080.

Intel Core i7 10700K

The i7 10700K succeeded the 9700K, which had failed before the Ryzen 3700X owing to the lack of hyperthreading. Due to the intense rivalry, Intel was compelled to include hyperthreading in the upcoming 10th generation i7. It now outperforms the Ryzen 3700X in virtually every way, making it the greatest high-end gaming CPU available.

It has a base speed of 3.8GHz and a turbo clock of more than 5.0GHz. With a decent AIO cooler, you can overclock it on a Z490 motherboard and get some more performance.

AMD Ryzen 9 3900X

Let me show you a situation similar to the one we observed with the i5 10600K and the Ryzen 7 3700X. However, there is one significant distinction. Though the i7 10700K outperforms the 3900X by approximately 5-7 percent, the core count has been substantially boosted over the 10700K.

It has 12 cores and 24 threads, making it an ideal choice for any standard desktop PC. I wouldn’t recommend this one for gaming alone, but it performs better than any of the other CPUs mentioned here for less than $450, so why not simply forgo the 10700K and go with this one instead?


If you ask me, the Ryzen 3700X is the greatest CPU for the money when it comes to the RTX 2080 since it not only has enough cores but it also costs less than $300. In terms of value for money, the I7 10700K is the quickest CPU for the RTX 3080, but the Ryzen 3900X specifications make it seem like a child for just $20 more. The Intel Core i9 10900K, which I didn’t include on the list since it costs over $500 and has less cores than the 3900X, will simply not be an effective option.
