The shortage of PC components and the growing mining trend makes gaming a very expensive hobby. One year ago, 4K gaming was considered too expensive because RTX 2080 Ti was the only graphics card capable of running games at 4K resolution and its price was over a thousand dollars. Now with the second generation of RTX graphics cards, the scene is quite different, and we are there with some of the best CPU for RTX 3080.
With a frame rate twice as high, the RTX 3080 may be among the best graphics cards based on the Ampere architecture. When it comes to 4K gaming, you should expect 120 frames per second in the latest titles. The launch price of this card was quite low about 699 USD which is half of the RTX 2080 Ti but now due to global shortage, it's selling on online stores roughly at 1200 USD.
While the performance and value of this graphics card is excellent, the increasing price is a real issue. To get the maximum benefit from this card, you also need a good motherboard, cooler, and power supply. There you can find guides on them that will help you get the best product for your build without breaking the bank, as well as a guide to the best RTX 3080 graphics cards.
So you have purchased your RTX 3080 graphics card, now it is time to check out the best CPU for it in 2021. We've a lot of guides there which will help you in building a complete gaming PC with this graphics card so don't forget to check them out.
The Ryzen 5000 series of processors was a great success to the company as the changes in cores makes them even better than the previous generation. As you might already know, the previous generations were also loved by the users. The support of PCIe Gen4 slots makes them even more appealing to users as Intel CPUs still lacks that, but you need an X570 or B550 motherboard.
The first option that I would recommend you consider with RTX 3080 is Ryzen 5 5600X, which is budget-friendly but performs similar to the Intel Core i9 10900K at 1080p resolution. The price difference between them is about $200, making R5 5600X more appealing to users and getting it the best budget CPU for gaming medal in its neck, which AMD started getting with Ryzen CPUs launch.
There might be better options from Intel for RTX 3080 but for a mid-range build where you only have to do casual gaming and small productivity tasks like Word, Excel and PowerPoint. Spending a little more can get you the AMD Ryzen 9 5900X, which is a beast to consider with this graphics card, and that CPU can handle heavy workloads and is best for gaming at 4K without compromising on in-game settings.
The 6c/12t seem to be low for modern gaming as these days’ modern games and heavy applications demand more cores and threads. The core layout of the Ryzen 5000 series has improved, and now the cache memory has better access to the cores, which makes them better than before. This is the thing that makes it better than i9 9900K at low res gaming at a price difference of 47% or even more.
AMD CPUs have a great overclocking advantage as you don’t need to pay more for a K series (like Intel) variant as all CPUs support it. The bundled cooler comes with it is good for stock clocks (3.7 GHz), while if you have some excellent aftermarket cooler, you can easily hit the boost clock (4.6 GHz). We also have a guide on coolers that you can use to overclock this processor, so don’t forget to check it out.
One thing that disappoints the user about these CPUs is their gen to gen price increase difference. The latest generation is slightly expensive than the previous one but still affordable. Also, these processors lack integrated graphics means you must need a dedicated graphics card on your PC to get the display. Overall it’s the best CPU for RTX 3080, but only if you are slightly low on budget.
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.
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 2021 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.
Lacks bundled cooler while AMD CPUs comes with sutiable cooler.
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.
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.
When you only have to play games and not have any workload to put on your PC, you are good to go with the Ryzen 5 5600X and can save a lot of money. Though there are users who have to do some high-end work and gaming on their machines, they can consider the Ryzen 9 5900X, which offers about double cores and threads as the R5 5600X.
This processor gives uncontested gaming performance, and you might already know that AMD is matching toe to toe with the Intel high-end processors but for a better price and value. It’s not the most powerful processor in the market because there is a better option, namely Ryzen 5 5950X, but that’s a bit more expensive, and for gaming and everyday work, this one is good. When it comes to this processor’s price difference, it’s about fifty percent expensive than the youngest sibling in this architecture and offers the same amount of doubled cores.
No matter how powerful a processor is, you can’t utilize its full performance without pairing it with a good motherboard and a cooler, and I would suggest you get X570 or B550 chipset motherboard for it. There are other options too, but these motherboards are offering PCIe Gen4 slots, which others lack. Also, for cooling, I would recommend you to get premium air coolers or budget AIOs.
You might be thinking that the predecessor (Ryzen 9 3900X) was also offering the same cores and threads, so why should we get this one? AMD redesigned the core layout in the new architecture and claiming that it’s the fastest processors architecture out there, and proved that with their processors.
The price and the missing bundled cooler are a bit disappointing for AMD users as they were available in the previous architecture processors and offer excellent performance at the stock temperature and RGB lights.
Not everyone can afford the Intel i9 10900K, and also some users even don't need it because it's way powerful for mid-range gaming and everyday productivity work. In that case, you can save more than 100 bucks with the Intel Core i7 10700K. This processor is excellent for mid-range gaming, and you can also use it for heavy workloads, while a little more OCing can give you an i9 10900 K-like performance.
This processor is much targeted for gaming while productivity tasks can also be done, but we compared it with AMD alternatives and found them better in multi-threading work. The latest Nvidia Ampere series of graphics cards are an excellent option for this processor. The Intel Core i7 10700K is priced the same as the previous processor but offers better value and performance.
The core count of this processor is the same as the previous generation as both offer eight cores, but this one provides sixteen threads with hyperthreading enabled. Nvidia cut off hyperthreading in the last generation, but in Comet Lake processors, it's back again. These specifications are enough for modern gaming, and even with it, you don't need to change the processor for the next two or three years.
As it's a K series processor, you will have a significant advantage with the clock speeds overclocking the processor and taking its performance somewhere similar to the i9 10900K. Though overclocking can't be done with some cheap motherboard in Intel CPUs, you need premium chipset motherboards like the Z490 to get the maximum performance out of this CPU, while cheap chipsets like B460 can't get it done.
A motherboard alone can't get the clocks of your processor from 3.8 GHz to 5.10 GHz, but you also need a good aftermarket cooler as this processor lacks the bundled one. We've dedicated guides on both the best motherboards for i7 10700K and coolers, too, so don't forgot to check them out. Running the processor on stock clocks doesn't need a high-end cooler, but you can also go with budget options.
The missing bundled cooler and the lack of PCIe Gen4 slots make the users look at the competitors like the Ryzen 5000 series processors. Another thing that disappoints the users of this processor is they need to repurchase a new chipset board, and the performance of this processor is not much better than the i5 10600K. Overall it's a great processor to consider with the RTX 3080 graphics card.
A couple of months before the Intel Core i9 10900K was the fastest gaming processor in the market and still its one of the best option you can get for your build. Though right now AMD has launched the Ryzen 5000 series CPUs where the 5950X seems to be much faster than the i9 10900K in modern games and productivity tasks at stock clocks.
The processor comes with ten cores and twenty threads which you know are enough for any gaming machine for at least two or three years and the good this is it comes with low per core pricing. Another plus of this processor is it is excellent in both gaming and productivity applications and you can use it for streaming, rendering for video editing and it will get its job done without any sweat. Though you are getting all of this performance for a high cost, not money but high TDP and heat which asks you to get some robust cooling solution for this processor.
As you might already know that i7 10700K can easily reach its performance by little overclocking but we are spending the extra 100 USD because this processor can also be overclocked at great extend. Though you need expensive components to overclock this processor and the more disappointing thing is if you are upgrading from the previous generation you have to change the motherboard too. As Intel was releasing a new chipset with every generation of their processors.
