Review

If you’re trying to leave no performance on the table, and want to have a future-proof system, then the I9 13900K will make that a reality. The RTX 3070 will suffer minimal bottlenecks even at the lowest of resolutions; you will absolutely get the most out of the RTX 3070 with the I9 13900K.

It is a bit overkill in my opinion, and you could definitely pair the I9 13900K with a better graphics card, but if you already have the RTX 3070 and are looking for a CPU upgrade, I’m only pointing you in the direction of the most powerful CPU. The 13900K will generate higher frame rates compared to the 13700K and any Ryzen competitor due to the high single-core performance.

If you’re not going to be gaming, and you need a CPU for streaming, 3D Modelling, or video editing, then the I9 13900K makes even more sense due to the multi-core nature of the processor. It has 24 cores and a boost clock speed of 5.8 GHz, any multithreaded task you throw at it won’t be an issue.

For gaming, just be aware that the majority of the cores will go unused which could be a huge waste of money since you’re not getting the full performance of your CPU. That’s why I’d recommend something a little more conservative such as the I7 13700K, it has fewer cores, but the single-core performance is quite identical.

If you utilize the I9 13900K with a well-capable motherboard, you can reap the benefits of “instant 6GHz” which is a feature exclusive to GIGABYTE Z790 motherboards. This will push the I9 13900K to run at 6GHz which is really impressive, and you will see the additional performance in many gaming scenarios.

The main competitor to the I9 13900K is the Ryzen 9 7950X, and these are both top of the line processors that are built to handle CPU-heavy tasks such as video editing, 3D modeling, and Software encoding.

My qualms regarding the I9 13900K revolve around its heat management and power consumption. It is apparent that, when the CPU is used at its maximum capacity (in my case, with software compilation and CAD programs), the I9 13900K will easily reach temperatures of 90C, and the power usage may be a cause for apprehension. However, this is the cost of having one of the top processors on the market.

How To Pick The Right CPU For Gaming

When choosing a CPU for gaming, it is essential to consider the essential features that will provide the best gaming experience.

These features include single-core performance, core count and L3 cache. Having an understanding of these three specifications will ensure that you can make an informed decision.

Why Is Single-Core Performance Important For Gaming

When it comes to gaming, single-core performance is essential, as most games are best optimized for a higher performing single-core.

If multi-core performance was more important, we’d expect gamers to invest in CPUs with high core counts such as Ryzen Threadrippers or I9 processors.

However, this is not the case; games can still run smoothly on I5 or even I3 processors, as long as the single-core performance is adequate.

Single-core performance is composed of clock speed and IPC, which usually improves with each CPU generation.

Why Core Count Is Important For Games

The number of cores in a system does not necessarily reflect the Frames Per Second (FPS) output, yet games are programmed to make use of multiple cores for enhanced performance.

Furthermore, many gamers enjoy multitasking by streaming or playing music in the background, and having multiple cores helps to facilitate such activities; in addition to optimizing the operation of the operating system.

Why L3 Cache Is Important For Games

The L3 cache plays an integral role in gaming, as it facilitates rapid data exchange, far surpassing the speed of RAM.

Without sufficient L3 cache, the CPU must retrieve instructions from RAM, slowing down the operation.

The Ryzen 7 5800X3D is a prime example, as its expansive L3 cache allows for superior performance in gaming.
