The newly announced Z590 chipset includes a slew of additional connection possibilities. The first of these new connectors is native USB 3.2 Gen 22 capability, which allows for a maximum transfer rate of 20 Gbps. Some Z490 board makers did integrate the port into their motherboards by using an ASMedia chip that was directly linked to the motherboard’s PCIe lanes.

The Maple Ridge Thunderbolt 4 controller is the next connection advancement. Although the transfer rate is the same as Thunderbolt 3, features such as support for 8K displays, enhanced security, support for longer connections, and tree chaining make the new standard worth considering, especially with more powerful integrated graphics incorporated into 11th Gen CPUs.

Both models offer comparable characteristics, so if this is important to you, the Z490 or Z590 will suffice.

CPU-Chipset Link

The Z590 chipset now includes eight DMI lanes with the CPU, which is double that of the preceding Z490 chipset. The additional lanes provide adequate bandwidth to the chipset for 8x PCIe 3.0 lanes, which can handle up to two M.2 SSDs at full speed. This capability, however, is only available for 11th Gen CPUs; earlier 10th Gen processors will switch to x4. As a result, the Z590 is better.

PCIe 4.0 Support

The PCIe interface is a significant feature when choosing between chipsets. The standard interface is significant since it dictates which CPU, SSD, and GPUs may be used. PCIe 3.0 was all the rage about a year ago. However, as it ages, PCIe 4.0 is increasingly taking its place. The enhanced performance ushers in a new age of express lanes on motherboards. The Z590 has 20 transfer lanes, while the Z490 has just 16 lanes.

The increased number of lanes gives the Z590 an advantage over the Z490, since it allows for greater motherboard and component connectivity.

Memory Support

Memory support for the Z490 is 2933 MHz DDR-4 memory. This is significantly less than the Z590. Without overclocking, the Z590 runs at 3200 MHz with the same DDR-4 RAM. The Z590 significantly improves memory performance. The Z490 vs Z590 motherboards have been built in such a way that overclocking improves their performance.

Both motherboard chipsets support DDR4 RAM overclocking up to 5333. If you want to use faster RAM, the Z590 is a better option for you.

Wireless Networking

While integrated WiFi is not required for the chipset, it is useful. If the chipset includes built-in Wi-Fi, it will perform better overall. If the motherboard already has Wi-Fi, this is an extra expense you won’t have to consider.

Wi-Fi 6 is available on both the Z590 and the Z490. This is the finest Wi-Fi standard for motherboards right now. It is next-generation and well worth upgrading to. It is far faster than Wi-Fi 6 m and substantially more future-proof.

USB Support

The USB 3.2 connector on the Intel Z590, which can handle rates of up to 20 Gbps, is a key feature. This enables improved communication and power supply. Most Z590 motherboards include USB Type-A and Type-C connectors. Six USB 3.2 Gen 2 connections and six SATA3 connectors are also supported by the Intel Z490.


If you care about overclocking, you should consider the entire power design. This will allow you to see a chipset’s thermal display Power to calculate overall heat dissipation. These chipsets may both be overclocked. Both have a 6W thermal display. Given this, you’ll want to make sure the chipset does not use more power than this.

For individuals who want to push their system to its limits, the Intel Z590 is a good choice. But, in terms of overclocking, the Intel Z590 has seen no notable advances.

The Z490 motherboard is available for $169. Some dealers charge as much as $600 – $650 for Z490 chipsets. High-priced motherboards typically have more external features such as more SATA and USB ports.

The pricing range for the Z590 motherboard is pretty wide. This motherboard has a starting price of roughly $180. The highest price we’ve seen is roughly $850-900. This motherboard costs far too much money. However, when we look at the specifications, it appears to be fair to some extent.

One thing is evident from the data above: the Z590 is significantly more expensive than the Z490. However, when we consider the gap in their specifications, it does not appear to be significant.

Why you should buy a Z490 motherboard?

Cheaper than comparable Z590 choices.

The Z490, an earlier generation chipset, will experience price reductions once the newer Z590 is released. Remember that Intel released the Z490 chipset for a premium range of motherboards, so features such as high-quality components, effective VRMs, and power supply systems will still be accessible without the need to upgrade to a Z590 chipset.

Z590 does not benefit from Intel 10th Generation CPUs.

10th Generation Intel Core CPUs do not support capabilities such as the PCIe 4.0. Also, the slower bandwidth between the older processor and the chipset, and Z590 motherboards will lose even more capability. We would advise against purchasing a Z590 motherboard unless you want to overclock a high-end 10th Gen processor such as the Core i9-10900K with high-frequency RAM.

A better choice for frequent users

If you are a frequent customer, you probably do not need features like PCIe 4.0 compatibility, USB 3.2 Gen 2 x2, or RAM overclocking. In such cases, the Z490 is a superior option, even for the i3 and i5 Rocket Lake processor families, because the cost reductions are considerable and can let you purchase a better component, such as an SSD or GPU.

Why you should buy a Z590 motherboard?

Improved chipset expansion

The increased bandwidth of the Z590 chipset owing to the doubling of lanes in the DMI link between the chipset and the processor allows motherboard makers to add extra storage, network, and other devices. Manufacturers that elect to add two M.2 slots may fully capitalize on this by providing two slots with full PCIe 3.0 x4 speeds.

PCIe 4.0 with 11th Gen CPUs

The 11th Generation CPUs with the PCIe 4.0 requires both a compatible chipset and motherboard. While all Z590 motherboards will offer hardware support, several Z490 choices from vendors such as ASUS will not.

Better connection

The newer Z590 motherboard has the latest peripherals, such as USB 3.2 Gen 22, which supports up to 20 Gbps rates, and Thunderbolt 4. If you feel that these additional ports will greatly improve your job, the Z590 is the only option. Furthermore, depending on the motherboard manufacturer, the extra PCIe 4.0 lanes can be configured for faster networking and communication.

My Final Verdict:

After all of this debate, the Z590 outperforms the Z490 in many ways. However, this does not render the Z490 obsolete. Because, in its current market environment, the Z490 is the lone competition for the Z590.

The Thunderbolt 4 interface speed and the 24 PCIe lanes significantly improve the Z590’s performance. Furthermore, the Wi-Fi 6-E connectivity boosts gaming performance significantly. However, the Z490’s 11th and 10th Gen support is also significant.

The Z490 is highly recommended for customers with a limited budget for creating a PC. Users with a larger budget, on the other hand, can purchase any of them, although I would prefer the Z590 over the others.
