Z490 vs z390

After Intel releases its 10th-generation processors, we will inevitably also see updated motherboard chipsets. One is designed for use with the 10th generation CPU. Once this happens, the reign of the Z390 chipset will definitely end.

As expected, Intel released an updated motherboard chipset, Z490, which flourishes with the 10th generation CPU and is one of the most advanced chipsets on the market.

As with all new versions, we found that many of you are curious about the difference between Z490 and Z390. Today we will answer this question for you.

In this article, we will discuss the main differences between the two chipsets and find out which one is the best choice for your next PC build.

There are five main differences between Z490 and Z390 that we are going to discuss today: LAN speed, plug type, wireless network, interface, and memory frequency support.

After reading this article, you will know which is better, Z490 or Z390?

* We recommend that you consider the CPU before starting this article, because your choice will affect the motherboard chipset for your build. The new Z490 chipset CPU socket is only compatible with 10th generation Intel CPUs.

Therefore, before choosing a motherboard, you need to know which CPU to use in your build. need help? Check out our series of articles on the subject here.

Note: If you spend some time researching chipsets on the Intel website, you will notice that their chipsets are actually called the Platform Controller Hub (PCH). Other brands such as

AMD choose to stick to the chipset. They are all the same in nature and provide the same functionality in your motherboard.

Both chipsets are bridge chipsets (meaning they contain the past South Bridge and North Bridge chipsets in one place). The key statistics of

Intel 3790 and 3490 chipsets are as follows:

very interesting start so v amos us Talking about PCI.

Some current and future Z490 motherboards will be able to run PCI 4.0. Unfortunately, this is something Z390 can't even dream of. If you want to upgrade your build in the future, it is a good idea to buy a Z490 motherboard now. Think of all the increased processing speed!

PCI Express has been proven to significantly improve the performance of graphics cards and hard drives. The current Intel

processor series (10th generation) does not currently support PCI express 4. Therefore, you have to wait until they release the 11th generation; The good news is that the Z490 motherboard will be compatible with Intel's 11th generation CPU.

Let's keep doing something less glamorous, sockets. We mentioned

briefly above, but it needs to be repeated again: the LGA 1200 socket that comes with the Z490 will not be compatible with traditional CPU models.

Z490 is equipped with LGA 1200, which is compatible with the 10th generation CPU and also compatible with the 11th generation CPU. On the other hand, Z390 is equipped with an LGA 1151 socket. They are compatible with 8th and 9th generation Intel CPUs.

This is important for the following three reasons:

is the same as these hardware brands, not to mention that AMD CPUs are not compatible with Intel motherboards and vice versa. For this part of the build, you have to be committed to a brand.

This is an area where we generally see improvements passed down from generation to generation. The jump from Z390 to Z490 is no exception.

The maximum memory frequency that the two chipsets can support is slightly different. Z490 provides an additional 263 MHz memory frequency. Compared with Z390's DDR4 2666, it achieves an impressive DDR4 2933.

Unfortunately, the Intel system is not sensitive enough, so this extra memory can have a significant impact on your game. However, overclocking is considered in the design of these two chipsets. You will notice that Z490 is more suitable for this method.

Z490 achieved another major victory in this category. The maximum LAN speed of the Z390 is 1.7 Gbps. Z490 can now provide 2.5 Gbps. This is an impressive leap between generations.

However, LAN speed can only be truly relevant in an alternative universe where we all have strong Internet connections. The average Internet connection in the United States does not support LAN speeds greater than 0.9 Gbps.

If you are one of the lucky ones who can enjoy 2.5Gbps speed, then Z490 is really worth considering.

Intel CNVi wireless technology is a new feature built into Z490. This is where the chipset gains the ability to run PCI express 4.0 (when the CPU finally catches up). This also means that the Z490 is equipped with WiFi 6.

Wifi 6 has power saving functions and is very suitable for gaming laptops. They have also been tuned to produce better performance and transmission speed in busy areas. They run

They are all the same, and their prices are definitely different. Best choice for


Z490 Best choice:

Z390 motherboards range in price from under US$200 to over US$400. We have seen Z490 motherboards from as low as $300 to over $600. This range includes a large number of brands. The consistent difference between all these companies is that the cost of Z490 is approximately $100 higher than its predecessor.

Is the extra money worth it? Let us consider the factors we mentioned today.

If you want to install an Intel 10th generation (or when the 11th generation comes out), then you really have no choice but to install a Z490. They are designed to run those more advanced CPUs. So many, that you can't actually insert anything else into it.

If you want to use PCI express 4.0, then you should choose Z490. Although it is currently not possible to run PCI express 4.0 on Intel CPUs when the 11th generation appears, the situation will change. Z390 will not be compatible with the 11th generation. Aside from the

CPU, Z490 just steals a victory in terms of overclocking and maximum memory frequency. As we mentioned before, the way the Intel system works, this additional 273MHz memory will not have a significant impact on the user or gaming experience.

If LAN is an important part of your gaming life, then you may want to consider switching to Z490, because it offers 2.5 Gbps compared to Z390’s 1.7 Gbps.

When your network bandwidth can support this LAN speed (or if you are lucky enough to have a good connection), this higher LAN speed will have a significant impact on your gaming experience.

Regarding network bandwidth, while waiting for the network to catch up with the PC, let's talk about Wifi 6. Not available on Z390, Wifi 6 can provide speeds up to 2.4 Mbps, which is 30% higher than the previous generation. Wifi 6 is also the reason why Z490 can run PCI express 4.0.

When our network bandwidth can run at these speeds, Z490 will truly become a force that cannot be ignored.

In short, Intel makes Z390 not compatible with Gen 10 CPU, which greatly reduces the value of Z390. Is this technological advancement necessary or wise marketing? Only time will give the answer.

We like to write about this section about products that are provided by or contain Intel components, because they are never a problem with their release.

When the Z490 was launched, many motherboards were available for purchase, including this chipset. Now, there is more. There is no problem with wearing gloves on one of them.

For more information on how to obtain the Z490 motherboard, please refer to this article.

Your choice of CPU will greatly affect your choice of motherboard. If you selected the previous generation CPU (8th or 9th generation), you should choose Z390. Not that, this is a bad thing. This is still an advanced motherboard that performs well in all major categories.

However, if you want a top-tier 10th Gen Intel CPU, you have no other choice, Z490 is what you need.

You will see that the Z390 cannot run the 10th gen CPU, it did not exist when it was released so theoretically they will have issues with power levels. But on a more practical level, you can't connect them to a newer CPU.

Since most of the responsibility for overclocking lies in the chipset, it is very important to have a sufficiently powerful chipset. If you don't do it right, you will see the real impact on your gaming experience.

The good news is that if you get the Z490, you will be able to run any 10th generation CPU, and you will most likely be able to cope with them after the 11th generation model is released (see this article for more information). Chapter

Who wins NS?

Well, they all won their games. The two cannot compete directly because they cannot run the same CPU. They both have big numbers in every key area. Z490 is better than Z390 in all respects. However, its value for your build will depend entirely on the CPU you intend to use.
