If you’re looking for the best GPU for the i9-12900K, check out the RTX 4080 Super. You might be wondering why we’re recommending the latest generation of GPUs to pair with a three-year-old Intel chip. The answer is that despite being an older chipset, it packs enough power to handle the newer GPUs easily.

On top of that, our RTX 4080 Super review showed that it performed exceptionally well at 1440p and 4K. So, if that is something you were looking forward to, you’ve found the perfect match.

This GPU packs 10,240 CUDA cores under the hood, a whopping 512 more than the base model. It also has a base clock of 2.29 GHz and a boost clock of 2.55 GHz. While these aren’t that much faster than the base models, it’s important to remember that GPUs focus more on handling and processing large data in parallel rather than speed, and that is where the additional 512 CUDA cores shine. So this means that you should be able to play demanding games easily at the highest settings, but you might experience a bit of a bottleneck at lower resolutions.

On top of that, it has 16 GB of GDDR6X memory with a 256-bit memory interface width. This is the same as the base model, but additional cores make all the difference. A higher-bit memory interface means a large amount of data can travel to and from the GPU without getting stuck in the pipeline. This means better efficiency and performance and a smoother gameplay experience.

Due to its 121 Teraflops of Ray Tracing cores, it should also deliver excellent ray tracing results. This means you should experience serene visuals in competitive and story-based games. That said, enabling RT does hit your FPS, and if you play competitive shooters, turning RT isn’t recommended.

According to Nvidia, you should be able to connect four independent monitors with this card at 4K 120 Hz. However, it might be difficult for the RTX 4080 Super to push a full 120 Hz across all monitors simultaneously. They also claim a maximum supported resolution of 4K 240 Hz and 8K 60 Hz. So, if you have a 4K monitor, you should be able to experience the full potential of this GPU.

Besides that, it has a 2.1a HDMI port and three 1.4a Display ports, which should be more than enough for a multi-monitor setup, whether you want it for productivity or a wide-screen alternative.

The RTX 4080 Super is 310mm in length, 140mm in height, and 61mm in height. These dimensions make it larger than the RTX 4090, which means you’ll need a big tower case to house it comfortably. That said, we’ve got you covered in that domain as well with our best case for RTX 4080 Super guide, which has the top picks available.

This GPU is also rated for an average power draw of 251W during gaming, with a total power draw of 320. These numbers shouldn’t be surprising, seeing the hardware it is packing, but this means that there should be a good amount of heat generated. So, to keep the temperature under control, it’s recommended that you upgrade your casing or PC fans, especially if the ambient temperature around you is high. So, if you’re interested in exploring potential upgrade options, our best 140mm case fans guide has you covered.

It also has 80 MB of AMD Infinity Cache, which stores frequently accessed data. The cache is close to the core, so whenever data is needed, it can be retrieved from the cache instead of requesting the VRAM to fetch it. This reduces access times, which leads to increased performance and efficiency.

This graphics card houses 20 GB of GDDR6 memory with a 320-bit memory interface. This means that there should be more than enough VRAM to turn up the in-game settings without overloading the memory. In addition, the 320-bit interface should ensure smooth data transfer to and from the GPU.

The RX 7900 XT also packs many performance-enhancing features, such as AMD FidelityFX Super Resolution or FSR. According to AMD, you should see a performance boost from 87 FPS to 135 FPS in titles like Immortals of Aveum at 4K with FSR3 NativeAA mode and Frame Generation enabled by turning on FSR. So, even if a title is giving this GPU some trouble, which is unlikely, you always have software options to give it a boost.

Regarding connectivity options, it has two 2.1 Display ports, one 2.1 HDMI port, and one USB Type-C. This should be more than enough to cater to a multi-monitor setup or handle the high refresh rate output of your monitor. Furthermore, it has a maximum supported resolution of 3840×2160. So, if you have a 4K monitor, you should be able to experience the full capabilities of this GPU.

How to pick the best GPU for i9-12900K

Before investing in any GPU, there are a handful of factors that you need to keep in mind. These factors should help you avoid needless upgrades and filter your options until you have the best balance between performance and value. We’ve listed some of these factors below to help you make an informed decision.


The first thing you need to consider is the price point at which different GPUs are coming. For example, a GPU costing over $1,000 could cost more than your entire build. That said, you could get it for “future-proofing” your setup, but with the Intel i9-12900K, the upgrade options end after the 14th generation, as the next generation will have a different socket.

So, it’s better to look for a GPU that complements the computational prowess of the Intel Core i9-12900K while keeping the cost under control and not going for an overkill option. This will also help save money that you can use to upgrade other components such as the RAM, SSD, or even your CPU to a more powerful chip like the Intel Core i9-13900K, which we also have a hands-on review of.

GPU size

An important aspect to consider is the GPU size and your casing. If your casing doesn’t have adequate space to house the card properly, you will have to spend extra money upgrading your case. On the other hand, if you do manage to fit it inside the casing, the airflow might not be great due to everything being cramped up. This will most likely lead to overheating, and you’ll need to invest in bigger and more powerful fans to keep things cool.

So, visit the manufacturer’s or third-party distributor’s website, look at the dimensions, and measure the space inside your casing. If it’s enough, go forward with the purchase.


GPUs and CPUs don’t have many compatibility issues, and even older-generation motherboards can support the latest-generation GPUs because the PCIe is backward compatible. The latest Nvidia 4000 and AMD 7000 GPU series all support PCI 4.0. However, if you have the newer PCI 5.0 motherboard, you should be able to connect your GPU without compatibility issues. However, the performance might be a bit compromised due to the limitation of PCIe 4.0.


There are various brands that offer different styles of the same GPU. Some examples include ASUS, Gigabyte, PNY, and more. Each brand has its own price for the same GPU, which increases depending on how many bells and whistles they include, such as RGB lighting and fancy backplates. However, that’s not all – they also manufacture overclocked versions, which come at an even higher price.

So, depending on your budget, you could get the same GPU at varying prices depending on the brand. Generally, ASUS ROG Strix GPUs fetch high prices, while other brands like PNY are relatively cheaper.

Our Verdict


After reviewing the different GPUs, considering their features, the technologies they have at their disposal, and their raw performance, there was a clear winner: the RTX 4080 Super. This is because it offers better performance than the RTX 4080, has 16 GB of GDDR6X VRAM, excellent 1440p and 4K results, and comparatively costs less than the base RTX 4080. On top of that, it supports various technologies such as Nvidia DLSS and Reflex, which work to boost its in-game performance, giving you a competitive edge and a pleasant experience.
