Since the Z590 motherboard only supports two generations of Intel processors, it shouldn’t be surprising that we went with the flagship 11th gen CPU, the Intel Core i9-11900K. 

For starters, this CPU has eight cores, 16 threads, a base clock of 3.5GHz, a boost clock of 5.3GHz, and a 16MB Intel Smart Cache. What this means is that it has enough hardware to handle a variety of gaming and professional tasks without compromising on performance. 

However, since it has a 14nm process and an older architecture, its performance isn’t comparable to the latest generation CPUs. However, it should still be able to hold its own against resource-intensive tasks. 

The Intel Smart Cache should also help boost the CPU’s performance, enabling all the cores to access the lower cache level. This means that the access and data retrieval time should be reduced, increasing the CPU’s efficiency and processing rate.

The 11900K has a high TDP of 125W, the same as the 13900K, which is leagues above it in terms of performance. That said, it does have a configurable TDP setting, which lowers it to a manageable 95W but also drops the clock speed to 3.0GHz.

However, the TDP could fluctuate depending on the workload, increasing the thermal output. External factors like the ambient temperature could also increase the CPU’s temperature. In either case, we recommend using a robust CPU cooler with a good thermal paste.

This processor is powered by six cores and 12 threads. On top of that, it has a base frequency of 3.9GHz, a turbo frequency of 4.9GHz, and a 12MB L3 cache. What these specifications mean is that it has enough firepower to handle casual and demanding gaming and professional tasks. 

However, since it only has six cores, it isn’t the best option for server or workstation-level tasks. That said, the power of “K” should come in handy as you can overclock it to make its processing even faster. Keep in mind that running your CPU in a highly overclocked state for extended periods can lead to damage. 

But, if you’re an enthusiast and want to get the most out of your purchase, we recommend striking a balance between performance and power consumption to better manage the thermal output. Also, consider using the best CPU cooler to keep it performing optimally, as it has a base TDP of 125W, the same as our top pick. This is a drawback to the older Intel CPUs as they aren’t power efficient, and the 11600K consumes the same amount of energy as the flagship CPU of the 11th and 13th gen. 

The 11600K comes with Intel UHD 750 Integrated graphics. This means you can run your system without a dedicated GPU, and the iGPU should be enough to power basic tasks, but gaming on it would be less than ideal. On top of that, it has a maximum memory bandwidth of 50 GB/s, meaning the data transfer to and from the CPU should be enough to handle some level of demanding tasks without running into bottleneck issues.

Overall, for the price, the 11600K has decent specifications, which should result in smooth everyday tasks and gaming. However, it consumes the same amount of power as the higher models, which brings its position down a notch. 

What users say

At the time of writing, the Intel Core i5-11600K has a 4.8 out of 5.0 rating and a handful of positive Amazon reviews. One reviewer stated: “The i5 11600K is the strongest performing and most flexible of the gen 11 i5 variants.” Other than that, its overclocking potential and overall performance were the highlights, and one user even said: “For under $250 this is bargain super chip for gamers and should be good for streamers as well.”

  • It has a PCIe 3.0 interface
  • It requires a high-end cooling solution
  • Its power hungry and has a high thermal output

11th-generation Intel CPUs aren’t the only ones compatible with the Z590 motherboard. The 10th-generation processors are also an option and are still viable. That said, for the best 10th gen CPU, we went with the i9-10900K. 

This pick might not be surprising for obvious reasons. It has impressive hardware that delivers excellent performance. This processor packs ten cores, 20 threads, a maximum turbo frequency of 5.3GHz, and a 20MB L3 cache. These specifications mean it should be more than capable enough to take on anything you throw. 

That said, we see similar trends when it comes to power consumption. It also has a TDP of 125W, which can be lowered to 95W using the configurable TDP settings. On top of that, it can be overclocked, which means it can perform better but will also consume more power and generate more heat. We recommend using the best water cooling kit to keep it tame and performing optimally. 

Another difference between the two generations can be seen in the maximum memory bandwidth. This CPU has a bandwidth of 45.8 GB/S, while the 11400F has 50 GB/s. That said, it should perform better than the 11400F due to its higher core and thread count and overclocking potential. 

The Intel Core i9-10900K also uses PCIe 3.0, but it should work with previous and next-generation components, albeit at lowered performance. While they are forward and backward-compatible, the design can’t change, and 3.0 Gen components will work only at the limit of that version. 

So, while the 10900K is almost four years old, it still holds its own against the competition and should serve you well in gaming and real-world tasks. That said, it has a high price tag of $450, and in that amount, you could get the 13900K, which is leagues above it in performance but isn’t compatible with the Z590 motherboard. So, consider your usage and spend your money wisely. 

What users say

According to Amazon reviews, it has excellent performance, and one user said: “If you are looking for the best gaming CPU, this is the one!” Many users were complementing its versatility to deliver top-notch performance in gaming, video editing, and other tasks.

How to choose the best CPU for Z590 motherboard

There are a handful of factors that you need to consider before choosing a CPU. This is particularly important when looking for a CPU to pair with a motherboard. Different motherboards have varying features and functionalities, and getting a high-end CPU for a low-tier motherboard could hinder its performance. So, to help you make an informed decision, we’ve listed some of the factors you need to keep in mind while making a decision. 


The first thing you need to consider is your budget and what it allows for. For example, spending $300 when your budget for a CPU is $150 will most likely put things out of balance, and you’ll have to compromise on another component or go above your budget, which is less than ideal. 

So, filter your options based on what is available in your budget and pick the CPU that offers the best performance and value ratio.  


The compatibility between the CPU you’re opting for and the Z590 motherboard is crucial. The Z590 motherboard has the LGA 1200 socket, and only Intel’s 10th- and 11th-generation CPUs are compatible. This means that your options are limited to two generations, which is good as it would make choosing a CPU easy, but to move to the newer generations, you’ll have to purchase a new motherboard. 

Cores and threads

The more cores and threads a processor has, the better it performs. Gaming doesn’t generally require a lot of cores or threads. However, a high core and thread count is important for heavy multitasking, as it is needed to handle various processes in parallel. So, keep this in mind while opting for a CPU, as it’ll impact the performance of your system.
