Features and considerations

The Intel Core i9-12900K was the highest CPU of Intel’s last generation. With this CPU, you can have the best performance out of any GPU you want to use. One of the first things you’ll have to consider is whether or not you want access to the new gen. With a CPU like the 12900K, you can easily bundle in a new-gen Nvidia or AMD, but also you can cut prices a bit and connect a past-gen GPU. The great compatibility between them will help out. 

When purchasing a GPU for a high-end CPU like the i9-12900K, consider the following:

Performance

The i9-12900K is a powerhouse CPU, so you need to choose a GPU that can keep up, aiming for high frame rates. (ideally above 144 FPS for smooth gameplay) at your desired resolution. Extensive benchmarks and reviews on our site will help you compare different GPUs and determine which one delivers the best performance for your needs and budget.

VRAM

VRAM (which is short for Video Random Access Memory) stores textures and game data. So, you need to choose a GPU with sufficient VRAM to handle high-resolution textures and demanding future games without bottlenecks. Now, higher resolutions require more VRAM. For 1080p gaming, 8GB might be sufficient, but 1440p and 4K gaming often benefit from 12GB or even 16GB of VRAM.

Cooling

Most powerful and high-end GPUs generate significant heat, so you need to look for a well-ventilated case with ample airflow to keep your system cool. Look for GPUs with robust cooling systems, like large heatsinks or liquid cooling options, to ensure optimal performance and prevent overheating. Further, ensure that the GPU fits into your case comfortably.

How much power do I need for an i9-12900K and a high-end GPU?

A 750w PSU should be enough to support an i9-12900K with a high-end Nvidia or AMD GPU. However, a slightly more powerful PSU in the range of 1000W is recommended.

Is an i9-12900K good for gaming?

If you’re looking to get the highest fps for the best gaming experience, then look no further. However, when compared to other CPUs, such as the 5900x, the price-to-performance comparison showed diminishing returns. So, for those on a budget, other CPUs may be more viable.

Does it come with an integrated graphics card?

The CPU does come with a UHD770 integrated graphics card. However, if you’re looking to run GPU-intensive software and the latest AA games, purchasing a separate GPU is highly recommended.
