Top 6 Best GPU For I9 12900K/KF

Picking the right GPU for your build is just as important as picking the right CPU; without a good balance between them, there will be a “bottleneck” which will cause either the GPU or the CPU to never be able to output 100 percent of its performance because either the CPU or the GPU is too weak; this is why choosing the best GPU For I9 12900K is so important.

If your GPU is weaker than your I9 12900KF, you are practically wasting money because you have purchased one of the best-performing CPUs and it will never be able to run at full capacity; essentially, you could have purchased a cheaper one and the performance would have been the same.

That being stated, we will provide you with various decent choices to choose from based on your budget.

Why should you trust our reviews/opinions?

Here at TechReviewTeam, we test every single GPU before writing a detailed review on them. Unlike other websites, we don’t simply write reviews on products we’ve never tested, while others write reviews based on “theoretical performance” that the product SELLER ADVERTISES, we actually take our time to test the product we talk about & share the knowledge with you.

EVGA GeForce RTX 3090 FTW3 Ultra Gaming

The best GPU for your I9 12900KF hands down. Powerful, fast, and well worth the price tag. It will result in 0% bottleneck issues.

It’s no surprise that our first selection is the NVIDIA RTX 3090. For many years, Nvidia has led the Graphics Card Market, and it appears that this trend will continue.

The 3090 is a very powerful card that will guarantee your system performs at full capacity at all times.

The I9 12900K + RTX 3090 combo should be able to handle even the most demanding FPS games.


  • The genuine boost clock is 1800 MHz, and the memory capacity is 24576 MB GDDR6X.
  • Real-time ray tracing in-game and cutting-edge, hyper-realistic visuals.
  • The combination of three HDB fans and nine iCX3 thermal sensors provides greater cooling efficiency while creating much less acoustic noise.
  • All-metal backplate, configurable ARGB, 3-year warranty, and world-class technical support from EVGA.

EVGA GeForce RTX 3080

Although it is not as powerful as the 3090, it will still perform an excellent job of avoiding bottleneck issues (or at least extreme ones) and providing durability to your system because you will not need to update this GPU anytime soon.

The RTX 3080 is essentially a 3090, except it is significantly weaker and less expensive. Although we say weaker, it is not weak; it is still a monster Graphics Card that will last you years and years without the need to replace or overclock it to stay up with gaming demands.

If the 3090 is out of your price range, we recommend taking a look at the 3080, which will leave you well happy.


  • The true boost clock is 1800 MHz, and the memory is 10240 MB GDDR6X.
  • Real-time ray tracing in-game and cutting-edge, hyper-realistic visuals.
  • Triple HDB fans provide higher cooling efficiency while emitting much less acoustic noise.
  • All-metal backplate, configurable ARGB, 3-year warranty, and world-class technical support from EVGA.

Radeon RX 6900 XT

It’s a touch pricey, but it’s one of the greatest GPUs for such a strong CPU, there’s no bottleneck, and this system will last you 5+ years without needing to be upgraded.

This Graphics Card is an amazing beast, as seen by its price. Obviously, this isn’t for everyone due to the price, but keep in mind that you chose to get an I9 12900KF, so no matter which GPU you choose, it will always be quite pricey unless you want to have a severe bottleneck.

With this GPU, you won’t need to replace your system anytime soon, and we can guarantee you won’t have any bottleneck difficulties and your system will be able to function at full capacity, which is what we call money well spent!


  • Game Clock: Up to 2050 MHz
  • Boost Clock: Up to 2285 MHz
  • External RGB LED Synchronization
  • Video Streaming up to 8K
  • High Performance 4K Gaming

GeForce RTX 3070

The cheapest GPU you should go for, otherwise, the I9 12900K will not be worth your money.

If you’re on a tight budget and can’t afford any of the other alternatives, the RTX 3070 should be the very minimum for you; if you have an I9 12900KF, you should never go for a Graphics Card that’s less than the RTX 3070. Even the 3070 will have some slight bottlenecking with that CPU, therefore any cheaper GPU will be a waste of money after purchasing such a strong CPU.

Having said that, the 3070 is still a good GPU for the money, and while it isn’t as strong as the others, it does the job.


  • NVIDIA Turing architecture, with core clock rates of 1500MHz and upgrade clock speeds of 1725MHz, is designed to meet the needs of demanding games.
  • Memory for creating stunning visual reality is provided by 8GB GDDR6 (256-bit) on-board memory, 2944 CUDA computing cores, and memory bandwidth of up to 448GB/sec.
  • PCI Express 4.0 graphical user interface – Compliant with a wide range of applications. For further connection, DisplayPort and HDMI outputs are offered.
  • Shaders of the type Turing Shaders exist. Concurrent floating-point and integer operation execution, adaptive shading technologies, and a new unified memory architecture enable amazing performance advances in today’s games.

RTX 3060 TI

We would argue this has to be the best cheap GPU, as it is around 20% better than the 3060. Low cost and good performance.


  • NVIDIA Ampere Streaming Multiprocessors
  • 2nd Generation RT Cores
  • 3rd Generation Tensor Cores
  • Powered by GeForce RTX 3060 Ti
  • Integrated with 8GB GDDR6 256-bit memory interface

It allows quicker deep learning inference for analytics engines using Ampere Streaming Multiprocessors and Tensor Cores, allowing enterprises to handle more information in less time.

It has 256-bit GDDR6 8GB graphics memory and will produce teraFLOPS of arithmetic processing power per Watt of electricity later this year.
Benefits include increased performance per watt, faster deep learning inference, and more analytic understanding on a large scale.

RTX 3060

The cheapest GPU we’d suggest; anything less is too old / considerably weaker / not worth the cost.


  • NVIDIA Ampere architecture, 2nd Gen Ray Tracing Cores, 3rd Gen Tensor Cores
  • 12GB 192-bit GDDR6, 15 Gbps, PCIE 4.0; Boost Clock 1807 MHz
  • IceStorm 2.0 Cooling, Active Fan Control, Freeze Fan Stop, Metal Backplate
  • 8K Ready, 4 Display Ready, HDCP 2.3, VR Ready
  • 3 x DisplayPort 1.4a, 1 x HDMI 2.1, DirectX 12 Ultimate, Vulkan RT API, OpenGL 4.6

With the announcement of a new product, the RTX 3060 has officially joined the ray-tracing revolution.

With NVIDIA’s Ampere Graphics Card architecture and 4th Gen Ray Tracing Cores, you can achieve throughput speeds of up to 8 Giga Rays per second. Furthermore, it provides a 3 frame buffer for RT if your PC is unable to keep up when TR is busy.

The RTX 3060 is the most cost-effective way to get into interactive ray tracing yet! With 2nd Gen Ray Tracing Cores, 3rd Gen Tensor Cores, 12GB 192-bit GDDR6 Memory, and improved clock rates (1807 MHz), this card is ideally positioned to bring immersive game engines to even more players at an affordable price!

Should I overclock my GPU?

You will not need to do so if you purchased an RTX 3070, 3080, or 3090. However, if you get a Graphics Card that is weaker than those three, it will be incompatible with your I9 12900K and you will still have a 5-10% block simply because your CPU is so powerful.

In such a scenario, you should absolutely think about overclocking your GPU to get some extra performance out of it and be able to compete with the I9 12900KF without any bottlenecks.

Is the I9 12900K/KF Good for Gaming?

Nothing beats a powerful CPU and GPU combo when it comes to gaming. This CPU is a top-tier processor from America’s foremost semiconductor manufacturer that will have you running all types of high-quality games at 1440p or 4K on maximum graphics settings with no trouble!
As long as your system’s GPU has enough power, this baby will never have FPS troubles when gaming for years to come!
