Best CPUs for RTX 3080

Best CPUs (processors) for RTX 3080

Have you bought RTX 3080 or gonna buy and looking for the best CPU for it? If you are, you landed in the correct place because in this post I am gonna discuss the best processors (CPUs) for Nvidia GeForce RTX 3080 graphics card.

Before starting, I am shortlisting them based on my personal taste and experience, if I can get good performance from them, you can get too.

Processors (CPUs)Specifications/My opinion
Intel Core i9 10900KExpensive, still best gaming performance
AMD Ryzen 9 3950XHigh-end CPU, more cores and threads, 2nd best for gaming
AMD Ryzen 7 3700XHigh-end gaming in budget price (around $300)
AMD Ryzen 5 3600XBest budget CPU for gaming, minimum for 3080

#1. Intel Core i9 10900K:

If you want the best gaming performance possible at this point, intel core i9 10900K is the best CPU. However, it is the most expensive CPU too and definitely overpriced ($777) (according to my view) but if you need the best CPU possible, money isn’t a factor, you should go with this.

Also, I always recommend high-end CPUs with these new Nvidia 30 series cards. Especially, as RTX 3080 can run games consistently 4K 60fps (or higher in most of the games), so you have to use that level CPU. Obviously, i9 isn’t compulsory, you can see the below options too at less price.

Intel Core i9 10900K comes with 10 cores and 20 threads. You get 4.9 GHz clock speed with this CPU that can be overclocked up to 5.3GHz, isn’t it amazing? The TDP (Thermal design power) of this 10th gen. i9 CPU is 105W. 

Also, make sure to buy Z490 chipset motherboards only. Because with LGA 1200 socket Intels, 10th gen CPUs only support only 400 series (Z490) chipset motherboards. 

Now, I have tested some games with RTX 3080 and with this CPU, let’s see they perform:

Benchmark in games:

System configuration used for the benchmark:

GamesResolutionPerformance (fps)
Doom Eternal4K163 fps
Horizon Zero Dawn4K67 fps
COD modern warfare4K77 fps
Assassin creed odyssey4K78 fps
Shadow of the Tomb Raider4K58 fps
Red Dead Redemption 24K73 fps

So, after seeing this amazing performance in 4K gaming, with CPUs like this, you can definitely utilize the full potential of RTX 3080 GPU.

My opinion:

I only recommend this CPU for dedicated gamers or those who need the best PC. But, for budget builders, don’t worry, this high expensive CPU isn’t the only choice available for you.


  • Comes with 10 cores and 20 threads.
  • Pre overclocked 4.9 GHz and up to 5.3GHz.
  • Has 125W TDP.
  • New 400 chipset motherboard required.

#2. AMD Ryzen 9 3950X:

If you want higher cores, threads at the cheaper price than i9, with GPUs like 3080, you can go with Ryzen 9 3950X too. It cost around $709, which is a bit less than the Intel 10th gen. i9 CPU.

This CPU is heaven for video editors, animation, tasks when you need rendering, higher cores. Also, for gaming, it got the 2nd position.

It comes with 16 cores and 32 threads. The max boost capacity of this CPU is 4.7 GHz. And has 105W TDP. Also, it is an AM4 socket CPU.

I like about AMD CPUs because they support old motherboards too. For example, both the 2nd and 3rd gen. AMD Ryzen CPUs support AM4 motherboards. Basically, you don’t have to change the motherboard while upgrading your CPU.

But, this AMD CPU needs a good cooling system, more than average. I think this is a demerit of it. Because it heats up more. Otherwise, it is also one of the top-end CPUs available in the market. 

Benchmark in games:

GamesResolutionPerformance (fps)
Doom Eternal4K158 fps
Horizon Zero Dawn4K73 fps
COD modern warfare4K75 fps
Assassin creed odyssey4K76 fps
Shadow of the Tomb Raider4K55 fps
Red Dead Redemption 24K75 fps


  • It comes with a 3.5GHz base frequency that can be overclocked up to 4.7GHz.
  • Contains a 64 MB L3 cache.
  • Has 16 Cores and 32 threads.
  • Has 105 TDP.

My opinion:

I recommend this CPU with 3080 only for tasks where you need higher cores. However, its boosted clock speed is less, but in actual gaming performance it almost negligible. But for dedicated gaming, the previous one i.e. i9 is the best.

#3. AMD Ryzen 7 3700X:

If you don’t want to spend $700-$800 in the CPU, but also want a good one around $300, this could be the best option for you, especially with high-end GPUs.

Since 3080 can run games consistently at 4K, you must have to get a CPU that can handle the performance, doesn’t create a bottleneck. In that case, I would go with Ryzen 7 3700X.

It is basically 8 cores 16 threads processor. The base clock speed of it is around 3.6 GHz that can be overclocked up to 4.4GHz. It comes with 65W TDP.

See, if you have $400 budget, then you can definitely go with Intel’s i7 10700K. I am not recommending that because you get almost the same (excluding gaming) performance in Ryzen 7 3700X, and surprisingly around $100 less.

The gaming performance is comparatively less in this CPU than Intel’s 10th gen. i7 but not very huge too. As I have personally used it, I saw only 3-7 fps difference with this CPU in 4k gaming.

Also, when you started playing higher resolution and refresh rate, games become GPU demanding. Meaning games use more GPU than CPU and high-end gaming. So, Ryzen 7 is a perfect fit for 3080.

Benchmark in games:

GamesResolutionPerformance (fps)
Battlefield V4K110 fps
Horizon Zero Dawn4K70 fps
COD modern warfare4K73 fps
Assassin creed odyssey4K73 fps
Shadow of the Tomb Raider4K59 fps
Red Dead Redemption 24K74 fps


  • It comes with 8 cores and 16 threads.
  • Its 3.6GHz base clock speed can be overclocked up to 4.4GHz.
  • 36MB game cache is available here.
  • Has 65W TDP.
  • Based on the AM4 socket.

My opinion:

It is a good budget CPU for 3080. For gaming, Intel Core i7 is a bit ahead than it, but in this price range, I think this CPU completely worth buying. As 3080 runs 4K, you are gonna need a CPU that can handle the power.

Also, I have said that at high-end gaming games become GPU demanding, so you can see a negligible amount of performance drop.

So, for gaming too I recommend this CPU, if you want high-level performance. But make sure to have a very good cooling system with this CPU.

#4. AMD Ryzen 5 3600X:

If you want the cheapest CPU that can handle RTX 3080, AMD Ryzen 5 3600X is for you. Under $200, it is a pretty solid option and doesn’t create bottleneck with high-end GPUs.

But, I only recommend this CPU if you have a very limited budget, otherwise, you should always go with a premium/high-end processor like Ryzen 7, 9, i9, etc. When GPU is boosted, I noticed that performance get from Ryzen 5 is less than a high-end CPU.

Not huge difference but you will see small performance difference.

Otherwise, for budget-wise, price to performance ratio, AMD Ryzen 5 3600X is the best processor available, known as the budget king.

It comes with 6 cores and 12 threads. It needs 95W TDP and contains 32MB cache. It supports up to 4.4GHz clock speed, around $200, amazing.

However, since at higher resolution, refresh rate games become GPU demanding, so this processor can also do that work, especially for high-resolution gaming (4K 60fps).

Performance in games:

GamesResolutionPerformance (fps)
Battlefield V4K98 fps
Death Stranding 4K91 fps
COD modern warfare4K69 fps
Assassin creed odyssey4K70 fps
Shadow of the Tomb Raider4K53 fps
Red Dead Redemption 24K71 fps


  • It comes with 6 cores and 12 threads.
  • Can give max frequently of 4.4GHz.
  • Supports AM4 socket.
  • It has 95W TDP.
  • Contains 35MB Cache.

My opinion:

If you have a very tight budget, don’t wanna spend much on CPU, Ryzen 5 is the minimum (I would say) with GPUs like 3080. However you more likely not to get any issues playing without overclocking the GPU.

But after overclocking 3080 at its full potential, I saw 5-10 fps drop that others in 4K with this PC configuration.

Otherwise for getting the best performance possible from 3080, you should use a high-end CPU.


I hope you like these CPUs (my CPU picks). I have mentioned them on my personal taste. And they can easily handle the power of RTX 3080.
