Best CPU For RTX 3080

Best CPU For RTX 3080

Gaming was not a cheap hobby, and for enthusiasts, half of the salary goes for computer components while the rest for living. A year before 4K gaming was quite costly because of the components' high prices, but with the release of these current-generation graphics cards, this has been totally changed. Now the Ampere architecture graphics cards offer double performance for half of the prices and consider them over the previous generation.

The performance and price of these graphics cards at one side, but you need other components that must utilize the full potential. Today we have got the RTX 3080, which is the Ampere architecture’s flagship card, and are listing up the best CPU for RTX 3080 in 2021.

If you are willing to put your hands on these graphics cards, you may also need to upgrade the motherboard, power supply, or casing. When it comes to the processors, our foremost choice is the Ryzen new architecture (Zen3) processors as they offer great gaming and multi-threaded performance. While on the other hand, we’ve got the Intel Comet Lake processors, which offer the same value as the AMD CPUs but have their own advantages.

Intel had the best CPUs for gaming throne for years, but with the AMD Ryzen 5000 series' launch, they got the best gaming processors medal. These processors are good as far as you want to game on your build and now willing to run some high-end productivity applications. The gaming performance of these processors is comparable to some of the top-notch options in the market.

There are better options than this processor in the market, but it makes no sense to consider building a PC for casual gaming and small productivity work (Word, Excel, or PowerPoint). Those users who consider some high-end processor will only get 3-10 percent performance gaming in modern games while at the same time the prices go about 50% more, which makes it the best value processor for gaming at this price. There are a couple of other graphics cards that you can also consider with this processor, and in fact, they are the best GPU for Ryzen 5 5600X.

Those users who are playing titles at 1080p and 1440p resolution with this processor will get the same performance as we see with an i9 10900K, which is 47 percent expensive. You don’t have to worry much about the six cores with that performance, which seems to be less for next-generation games. The core layout and the access to the cache memory are better than before.

Another great thing you will see in this processor is the PCIe Gen4 slots, which you know offers double bandwidth compared to Gen3 and currently is not available in Intel CPUs. It would be best to have a good B550 or X570 motherboard in your build, while there is some best motherboard for Ryzen 5 5600X.


  • Outstanding single core performance.
  • Performs well in multi threaded applciation.
  • Excellent price to performacne value.
  • PCIe Gen4 gives it advantage over the Intel alternatives.
  • Power consumption is relativly low so you can better OC it.


  • Nothing to mention.

Intel Core i9 9900K

Model Intel Core i9 9900K
Cores 8
Threads 16
Base Clock 3.60 GHz
Boost Clock 5.0 GHz

The performance and the value which the Intel Core i9 9900K offers is rarely available in any other processor in the market. This processor might not be the winner in 2021, but it was the fastest gaming processor of 2020 and still have a gold medal in the neck.

This processor comes with eight cores and sixteen cores which makes it futureproof for two or three years and it can run most of the demanding titles at 4K resolution with great in-game settings when paired with RTX 3080. The base clock of this processor is 3.6 GHz, but more impressively it has 5 GHz of boost clock you can easily achieve with a good CPU cooler, or it will be an electric heater in your house. Kidding!

This processor’s compatibility with motherboards is excellent as it can be paired up with all of the three chipsets. Still, with the entry-level chipset, its performance will become garbage. I would suggest you get the Z390 chipset motherboards because they can overclock this processor (others don’t) and you can get the maximum output from it. Overclock also needs good aftermarket cooler because it lacks the bundled one though you can even get some air cooler like NH-D15 to overclock this gaming beast.

While playing modern titles with this processor, you can also stream the game because it has enough resources to handle streaming with a high bitrate. When you pair this beast with RTX 3080, you can easily do 4K AAA gaming without even thinking about in-game settings and frame rates while for those who think its performance is not enough for them can overclock it up to ten percent.

Long story short if you are looking for an overall best processor that can do well in games and multi-threaded applications without spending a lot on other components to run Intel i9 9900K might be the only option.


  • Impressive single core and multicore performance.
  • Can be overclock with some mid range Motherboard.
  • Boost clock up to 5 GHz.
  • Best gaming processor of 2020.


  • Goes hot when running at boost clock so get a potent cooler.
  • Lacls bundled cooler while AMD CPUs comes with sutiable cooler.

AMD Ryzen 9 3900X

Model AMD Ryzen 9 3900X
Cores 12
Threads 24
Base Clock 3.8 GHz
Boost Clock 4.6 GHz
TDP 105

The Intel Core i9 9900K was a great gaming processor of 2020, but the multi-core performance of this processor was not that great and if you have to do work that demands more multi-core performance you can get the Ryzen 9 3900X. This processor is good to consider when you have to do productivity tasks on your build more than gaming, and it makes sense because of the additional cores and threads.

This processor’s specifications are excellent as it comes with twelve cores and twenty-four threads where the successor comes with the same specification but for a high price. These cores and threads are enough to handle any game and application in upcoming years, and you can easily max out most of the titles released. Even games like Red Dead Redemption 2 or Cyberpunk can be easily played with this processor, and it can run them without any sweat and moreover how can we forget the 4K gaming performance of the beast we are going to pair with it.

I wouldn’t say that this motherboard can be overclocked with some cheap motherboard but as compared to Intel alternatives the AMD chipset motherboards are slightly less expensive like the B550 while they also have PCIe Gen4 slots which Intel lacks. You can get any motherboard from X470, X570 or B550 if willing to run this processor at decent clock rates and want to enjoy the faster PCIe slots.

I’ve noticed that most users don’t like in this processor is its single-core performance even with the twelve cores. Intel leads the game to the performance for raw gaming but for those who want single and multi-core performance AMD is the foremost option to consider.

All you need to do is get an X570 or B550 motherboard and a good aftermarket cooler and pair them with this processor and RTX 3080, and you can enjoy the best gaming experience without thinking about frame rates or resolutions.


  • Better than competitor at the same price.
  • Incredable multi-core perfomance
  • PCie Gen4 slots which Intel lacks.
  • Compatiable with entry level B550 motherboards.


  • Lacks integrated graphics.
  • Twelve cores but still no single core perofmance.
  • Requires expensive motherboard for overclocking.

Base Clock 3.8 GHz
Boost Clock 4.7 GHz
TDP 105W

The Ryzen 7 5800X comes at a very confusing price. If you can invest a little more money, you can get Ryzen 5 5900X, while saving a bit can get you Ryzen 5 5600X, but due to better performance than its younger brother (5600X), you can consider it for your build.

If you need more performance, like to stream the game, or want to do some heavy rendering or video editing, this performance is an excellent choice without spending a lot of prices. It offers eight cores and sixteen threads, which are enough for today’s casual gaming, while supports overclocking if you want additional performance. The base clock of this processor is 3.8 GHz, while you can easily take it up to 4.7 GHz with some potent aftermarket cooler, and as it lacks the bundled one so, you must have to go with the aftermarket coolers.

4K AAA gaming is not a deal for this processor as it can easily handle any title running without any sweat. With RTX 3080, you will enjoy an excellent gaming experience. AMD claims that the Zen3 cores are the fastest in the world as they’ve redesigned the core design, and instruction per clock has also been improved.

The price difference between this processor and Ryzen 9 5900X is about 22 percent, but the other processor also offers 40 percent more cores. If you have to play games, I suggest you get the Ryzen 5 5600X, but those who have to put some extra burden on their PC can put their hands on this one.

There are some motherboards for Ryzen 7 5800X, which will allow you to get the maximum performance out of this processor, and you can overclock it like a boss.

There comes the beast which is one of the most powerful gaming processor though for pure gaming this processor is not recommended because Ryzen 5 5600X is enough for that you can get enough performacne from that processor. The uncontested gaming performance

The aforementioned processor was well enough, and you don’t need to invest more on CPU if you want to do casual gaming on your build. Though for uncontested gaming performance and sigh high workload, the better option is AMD Ryzen 9 5900X. This processor stands toe to toe among the top competitors from Intel and offers the best gaming performance.

Maybe you might know that this processor is not the best powerful offering from AMD because there is something more powerful than users can get. Yes, I’m talking about the Ryzen 9 5950X, which is good for heavy workloads, but it doesn’t make any sense to consider gaming. Instead, you can consider Ryzen 9 5900X, which is 50% expensive than the Ryzen 5 5600X but slightly cheaper than the Ryzen 5 5950X. To get most of the performance out of this processor, you may also need some good motherboard and cooler as it needs expensive components for overclocking.

The twelve cores and twenty-four threads of this processor make it futureproof, and you don’t have to worry about games and applications to run on it. Pairing it with RTX 3080 can give you great frame rates at 4K settings, and you can enjoy the real experience of the Nvidia Ray Tracing technology while both the CPU and the graphics card can run titles without any sweat.

This processor’s price is slightly higher than its predecessor and is not recommended for mid-range builds. Integrated graphics were missing from the start of the Ryzen series CPUs, but with the Zen3 release, AMD also cut coolers with their processors, which might be disappointing for a few users. Those coolers are capable of running the processor on stock clocks and offer RGB effects, which gives them an advantage over the competitor.

While buying the graphics card, most gamers think that it’s only the thing in their gaming build that will increase the frame rates. A couple of things affect the games' overall performance from which the CPU is one. With the latest graphics cards launched its will be good enough to pair the Comet Lake CPU, and there we have got the i7 10700K to pair with RTX 3080. You can call this processor a refreshed model of the i7 9700K with hyperthreading enabled and better performance and clocks, and these things make it considerable over it. This processor is futureproofed as you can use it for the next two or three years, but the more important thing is the next generation CPUs are most likely to use the same socket and chipset as this one.

There are even more powerful processors than this one, like the Intel i9 10900K, but for hardcore gaming, this one’s performance is enough, and we don’t need to spend the additional money on that CPUs. When paired with RTX 3080, you can get great frame rates, especially with games like Red Dead Redemption 2 and Far Cry 5, performance-hungry. Intel processors are known for single-core performance, while this one has enough cores and threads, which allows to stream with gaming. Previously Intel cut off hyperthreading from their Coffee Lake mainstream processors, and that was a good thing, but with these Comet Lake CPUs, they again enabled hyperthreading, and this processor comes with 8/16 cores & thread.

Both i7 and i9 processors are good to consider for these graphics cards, but i9 is relatively fast in performance, but not always faster is better. Sometimes we don’t need the extra cores and threads or the performance, and for that, we can save a bunch of money for some other components, and if you are the one who doesn’t need i9 performance, can consider this one. A few Coffee Lake processors don’t come with the bundled cooler, but this one comes with one good as far as you stick with the stock clocks. The motherboard you need for this processor is of Z490 chipset, which is powerful enough to overclock this processor and supports the high-end models too if you have any plan of upgrading in the future.
