It’s time to update this list! It’s been a year since we last updated our best CPUs for RTX 3070, 3080, and 3090.

Recently, I published an article comparing the Benchmark ratings of the RTX 3070, 3080, and 3090. It turned out to be fairly popular, so I thought I would update it with a new list that reflects the performance of the new RTX 3070.

If you’re looking for the best CPU for your budget, then there is no need to go with the most expensive CPU in this list. Of the 7 CPUs in the lineup, the CPU that costs the most is the one that is the best CPU in terms of performance. Here are the results of our benchmark test to give you an idea of how each CPU performs.. Read more about best cpu for rtx 3070 2021 and let us know what you think.

On Nvidia’s recent reveal event, they unveiled a new lineage that includes a slew of new gaming tools and capabilities, as well as potentially anything connected to the idea of “8K.” It’s fantastic to see that these monster-of-a-performance cards can perform at 8K. To be clear, having an RTX 3000 series dream does not imply price reductions or subsidies. These cards are colossal, and they’ll bankrupt you by the time you’re 30. These cards claim to provide the greatest levels of performance, seamless gaming, and brilliant dazzling visuals, among other things. The GA102 graphics processor, which has approximately 10496 shaders, is to blame (shading units). The amount of shaders accessible in your GPU is the foundation of rendering. That takes us to the best CPUs for RTX 3070, 3080, and 3090, which will be proportionately higher in category/tier due to the power constraints of these new GPUs. 

Nvidia also promised that the cards will have 328 texture mapping units and approximately 112 ROPs, indicating that this is the company’s largest bet. No one thought it would ever happen. According to a newly released YouTube video, the RTX 3080 performs approximately 45 percent better than the RTX 2080 Ti. I’m at a loss for words! If you’re searching for the best CPUs for RTX 3080 or RTX 3090, I’d recommend going with AMD’s Threadripper or Intel’s 9th/10th generation processors. Furthermore, I would advise you to investigate Nvidia’s Founder editions, which are magnificent and spellbinding.

How did we gather information for these three cards and connect it to the best CPUs for the RTX 3070, 3080, and 3090?

Because we didn’t have anything, determining which CPU would best fit the concept of “RTX 3000” was complicated and time-consuming. Consider collecting information on an entity that does not yet exist. Isn’t it terrifying? There were several performance leaks and IGN’s newest films regarding core temperatures and their performance versus prior card models, which caught us off guard. We drew a mind map to link all the dots, which helped us figure out the proportion of bottlenecks that had been eliminated. Do not anticipate the RTX 3070, 3080, or 3090 to operate without bottlenecks on your i5 or i7 3rd generation CPU at this time. One of your components will eventually slow down.

We selected extreme gaming CPUs to solve this issue since the RTX 3090 would work well on processors like the 10900K and 3700X. To me, that seems like a really rich arrangement. It’s worth noting that, since the number of CUDA cores has been increased by a little amount, it will undoubtedly consume and depend more on CPU cores and threads. It’s common knowledge that your CPU and GPU work in tandem to provide a smooth gaming experience. The 3970X, a monster of a CPU with approximately 32 cores and 64 threads, will be the most powerful AMD contender on the list. A series of PCIe lanes and additional RAM support are also included. The 10th generation i9, on the other hand, will perform well if you are prepared to pay for it.

It’s time to recommend some of the finest and most suitable CPUs for the RTX 3070, 3080, and 3090. Let’s get started on the tutorial without further ado!

The AMD Threadripper 3990X is the best overall CPU.



Cores: 64
128 threads
2.9 GHz is the base clock.
4.3 GHz turbo clock
TDP: 280W

AMD Ryzen Threadripper 3990X is a great fit for GPUs like the 3080 and 3090. I contemplated not gliding over any goods and profiting from my skewed viewpoint. Given the current backlash against Intel’s high-priced CPUs, AMD has taken a considerable lead in price-to-performance. The Threadripper 3990X is one of the most powerful processors available. The processor’s specs show that it has a staggering 64 cores modular, which is much more than Intel’s existing 32-core CPUs. The threadripper also has 128 threads for doing complex mathematical and graphical computations. This is unexpected since the workload on the RTX 3080 and 3090 GPUs will be at an all-time high, producing more requests particularly. It’s a complete win-win scenario as long as your CPU and GPU get along, regardless of how costly the goods are.

Surprisingly, the CPU has a 288MB combined cache and an AMD TRX40 module for improved performance. It’s worth noting that the CPU will handle quad-channel DDR4 memory modules and a total of 88 PCIe 4.0 lanes, which is a first. Because the socket is sTRX4, you’ll need to get the most recent version motherboards for your CPU. You will be the one in utter pleasure and excitement at the end of the day, notwithstanding the motherboard’s conundrums. Last but not least, the processor’s base frequency remains at 2.9 GHz, which is a bit low when compared to other processors’ base speeds, but to compensate for this, the 3990X’s highest boosted frequency rises to 4.3 GHz. Furthermore, the processor’s average TDP is 280W, which is very high, implying that you’ll need a good power supply to operate both your GPU and CPU.

Best Enthusiast CPU: Intel Core i9-10900K



Cores: 10
20 threads
3.70 GHz base clock
5.3 GHz turbo clock
TDP: 125W

The price to performance ratio is why I chose Core i9-10900K for the second number. People seemed more calm and delighted on AMD CPUs than on Intel processors, according to recent evaluations, but let’s not go off track. Because both chipsets feature an alignment algorithm, the CPU is better suited for the RTX 3080. Not to add, you may utilize the same CPU for the RTX 3070 and 3090, but you may notice 5% to 10% bottlenecks due to the chip’s dustiness. In any case, the CPU has 10 cores and 20 threads, which is a reasonable measure of performance. The AMD 3990X’s massive 64 cores make Intel’s CPU seem a little drab and harsh. These ten cores and twenty threads should enough to operate your RTX 3070, 3080, and 3090 GPUs.

Aside from that, you get a base frequency of 3.70 GHz, which is incredible in and of itself. Surprisingly, the Intel’s limit may be pushed up to 5.3 GHz, which is very impressive. The total system performance will improve by 15% at this frequency. Not to add, your CPU supports up to 128GB of RAM, which is more than enough to handle all of the newest AAA games. Furthermore, the chip includes an integrated GPU module that turns on your CPU without the need for an external GPU, but since you’re all purchasing RTX cards, it’s not much of a benefit. Yes, you may utilize the integrated GPU module for diagnostics. Aside from that, the same Intel CPU supports a staggering 4k resolution, meaning you can play 4k games without any known problems.

Best Gaming CPU: AMD Ryzen 9 3950X



Cores: 16
32 threads
3.50 GHz base clock
4.7 GHz turbo clock
TDP: 105W

It’s time to offer AMD Ryzen 9 3950X, another outstanding entity in 2021, a warm greeting. The thread ripper has 16 cores and 32 threads, which is more than Intel’s 10900K processor. Furthermore, the CPU is inexpensive when compared to costly Intel processors. I’m not sure why I feel the need to emphasize this, but AMD CPUs provide the same performance ratio as Intel processors at a lower price. The CPU is based on the Zen 2 architecture and is manufactured on a 7nm device. This, in my view, is really commendable, since such a tiny chip with such a high transistor density is either the work of an artist or the work of a GOD. Because the CPU utilizes the AMD AM4 platform chipset, it can be installed on either the X570 or B550 motherboards without needing to update.

Aside from that, the processor’s base clock remains at 3.5 GHz, with a turbo frequency of up to 4.7 GHz, which is really commendable given the price/performance ratio. Because the Threadripper is such a power-hungry CPU, the amount of heat produced will be unprecedented. To deal with this issue, you should utilize a liquid cooler to lower the high temperatures. Aside from that, you can only use DDR4 memory with two dual memory channels, which is a disappointment. Last but not least, this GPU’s overall gaming performance was outstanding. With the RTX 2080 Ti, games like Final Fantasy XV played at 4K without stuttering.

Best Overclockable CPU: Intel Core i9-9900KF



Cores: 8
16 threads
3.60 GHz base clock
5.00 GHz turbo clock
TDP: 95W

I have something special in store for overclocking aficionados and freaks, and it’s the Intel Core i9-9900KF. Although the processor is optimized for the RTX 3070, it is also compatible with the RTX 3080 and 3090. The explanation is straightforward. It’s a 9th generation CPU, which is a bit out of date for high-end gaming cards like the RTX 3090. It’s simply that the AMD 3990X or a 10th generation CPU with RTX 3090 are my personal favorites. In any case, the card is thrilling and has sophisticated characteristics such as a high transistor density. This implies that your CPU will be working closely with your new GPU around the clock.

Furthermore, the chipset only has 8 cores and 16 threads, which is a letdown. I’m not totally opposed to the CPU since it has a fantastic top boost frequency of 5.00 GHz, making it ideal for overclockers. The reason for sneaking in a biased view is that the CPU hasn’t been operating at its best even on the RTX 2080 Ti. Nonetheless, sophisticated characteristics such as a maximum slotted capacity of 128 GB of RAM and a maximum theoretical memory bandwidth of 41.6 GB/s make it an outstanding creature.

Aside from that, you’ll receive instruction sets for a smooth and consistent performance. Intel SSE4.1, Intel SSE4.2, and Intel AVX2 are among them. All I can say is that it’s a magnificent product that incorporates all of the possible features for 4K running games.



Cores: 18
36 threads
3.00 GHz base clock
4.60 GHz turbo clock
TDP: 165W

It’s one of those CPUs I’d give everything for. I’m not a big admirer of Intel, but the Core i9-10980XE exudes a sense of superiority and a desire to achieve better. The X series is a recently discovered module that comes after the “K” variants. The X series, after all, is renowned for delivering extremely valued performance and overclocking characteristics. For example, this CPU has a base frequency of 3.00 GHz and can be overclocked to 4.60 GHz. I realize it’s below the 5.0 GHz margin 9900KF, but did you look at the amount of cores and threads for a second? Obviously, you did not. The CPU has a total of 18 cores and 36 threads, which, in my view, is very respectable and applaudable. To be honest, this CPU will function well with the RTX 3080 and 3090 with no percentage bottleneck since the amount of cores and threads will guarantee that all data from the GPU is processed inside the bottleneck time limit.

Aside from that, the CPU features a clever 24.75 MB Intel cache for improved performance. There’s something unexpected in store for you! The CPU supports up to 256 GB DDR4 RAM, which is unique to the “X” series and only available in the “X” series. In the end, such a figure will boost your gaming system’s overall performance. Furthermore, the total temperature of the chipset is lowered from 105 to 86 degrees, implying that the chipsets in the “X” variants are more robust. To be honest, this processor holds a special place in my heart!

Best Value AMD Ryzen 9 3900X CPU



Cores: 12
24 threads
3.80 GHz base clock
4.60 GHz turbo clock
TDP: 105W

Thank you to AMD for creating the Ryzen 9 3900X, which is yet another excellent product on the list. The CPU has 12 cores and 24 threads, which is more than enough to handle any AAA games released to date. These cores and threads also make the CPU compatible with the RTX 3070, 3080, and 3090. Furthermore, the CPU has a 3.8 GHz base clock and a 4.6 GHz turbo frequency. This implies that the bulk of the programs, particularly blender and Maya, will work well. It’s worth noting that AMD processors are renowned for their superior rendering capabilities. Since modeling and re-creation fall within the rendering area, the RTX 3090 is a card with 24 GB VRAM, making it extremely compatible with all 3rd generation threadrippers.

Aside from that, the CPU comes with a specialized cooling system called Wraith prism. Because the CPU is from the Threadripper family, it’s safe to assume that temperatures will rise. In any case, dual-channel DDR4 memory with speeds up to 3200 MHz may be installed. Not to add that the highest temperature threshold for overheating is 95 degrees, which is sufficient to operate the CPU in dynamic conditions. Finally, the CPU needs 105W of electricity from your power supply.

The AMD Ryzen 7 3700X is the most affordable CPU.



Cores: 8
16 threads
3.60 GHz base clock
4.40 GHz turbo clock
TDP: 65W

It’s the final item on our list, but that doesn’t imply you should avoid it just because it’s last. Anyway, the Ryzen 7 3700X is a subsidized or watered-down version of the Ryzen 9 threadripper family, but it is still a threadripper. Aside from that, the CPU has 8 cores and 16 threads, which is more than enough to operate the RTX 3070 without a bottleneck. These cores also guarantee that the majority of GPU requests are handled within the specified time frame. It’s worth noting that the CPU has a base frequency of 3.6 GHz and a boosted frequency of 4.4 GHz, which I think is a great feature.

In addition, a specialized Wraith prism RGB cooler is included to help with the increasing heat. Threadrippers are notorious for overheating, and to cool them down, you may use either the standard cooler or a liquid cooler. Make your decision based on this.

Furthermore, the processor’s maximum rated temperature is 95 degrees, making it suitable for use in dynamic climatic zones. Furthermore, the CPUs’ necessary TDP is just 65W, which is very low. Overall, it’s a good and ideal CPU for the RTX 3070.

Putting the last pieces of the puzzle together

You may be thinking that the information provided is skewed or that it belongs to the more costly CPU lineage, but trust me when I say that we put in a lot of work to find these pairings after testing these CPUs against each RTX model. You won’t believe me when I say that the findings were overwhelmingly positive, particularly with the RTX 3090. If you want my opinion and suggestion, I would recommend buying AMD Ryzen 9 3990X since it is the only beast CPU on the list.
