Top 6 Best CPU For RX 580 – Expensive & Budget Choices

A CPU is a very important component for your computer, and if you are looking to buy a new one, it can be difficult to know which one will best suit your needs. If you have an RX 580 graphics card that you want to use or plan on getting in the future, then this article is perfect for you! We’ve done the research so that all you need to do is read on and decide what type of budget you’re working with.

Our list will include expensive options and budget options, it’s up to you to decide which will suit you the most based on your budget.

What to look for when picking a processor:

  • Type
  • Core Count
  • Clock Speed (GHz)
  • Cache Size (Liters)
  • Can overclock

The best CPU for RX 580 will have a high core count, clock speed, and cache size. The higher these numbers are the better it will be when running games or applications that use your GPU heavily. Even if you’re not into gaming yourself, having at least one of those three things in a computer is necessary to run any type of application.

We also suggest that you pick a CPU that can overclock, especially if you pick a budget CPU. If you picked one of the best processors on the list then you don’t need to overclock at all.

Top 6 Best CPU For RX 580 

CPUOur OpinionCheck Price
I7 11700KMost powerful CPU in this list, there are better ones but you'll already be able to use your RTX 3070 at 100% performance with this one.
I5 11600KA bit worse than the I7 11700K but still easily the 2nd best option.
Ryzen 7 5800XA bit worse than the other 2 options due to being released prior to them, however it's still a very solid choice.
Ryzen 5 5600XAnother solid choice, perfect for a mix of being cheap + decent performance
I5 10600KSame as the Ryzen 5 5600x except the intel counterpart
Ryzen 7 3800XWeakest CPU we would suggest you to get, any weaker than this and the bottleneck will be huge.

  • PCIe Gen 4.0 Support
  • No thermal solution included

Unrivaled performance and thrilling gaming: the Intel Core i5-11600K is the newest member of the Intel Core i5 family of processors. You’re ready to showcase your gamer credentials with competition level overclocking memory speeds and PCIe Gen 4.0 support, allowing you to achieve your full potential in titles like Destiny 2. It does not contain a thermal solution, so if you want a cooling device that meets your demands, you’ll need to buy one on the side, and we recommend a decent one because you’ll want to overclock this processor later on.

Will the RX 580 bottleneck any of these CPUs?

It will bottleneck the I7 11700K and the I5 11600K since they’re from the latest intel gen and have insane performance, however, this can be offset by overclocking your GPU, this way there won’t be much of a bottleneck and the performance quality you’ll have will last you for 3-4+ years.

What is a bottleneck?

A bottleneck is a limitation in terms of processing power and can happen when the processor or GPU doesn’t have enough power to handle all tasks that are thrown at it.

When this happens, you’ll notice performance dips or lags during gameplay which will be bad for your experience. When choosing a CPU there’s more than just price and brand to consider; make sure it has enough power to run well with other components such as GPUs so that you don’t end up with any bottlenecks!

How do I avoid buying a bottleneck?

Avoiding buying bottlenecks boils down mainly to understanding what type of games/software you’re going to use on your PC before making an expensive purchase. Make sure not only the CPU but the GPU as well are both compatible and provide roughly the same performance.

Should I overclock my CPU and RX 580?

We recommend that you overclock your processor if it is not one of the best CPUs on this list. With an overclocked RX 580, you’ll be able to get more performance out of both parts, especially if the CPU is more powerful than the RX 580 is.

The benefit here is that overclocking will increase the performance of both components which means you may not need to buy the very best processor as long as you’re willing to do a decent overclock which can end up saving you some money.
