Z790: A Refined Version Of Z690

Z690 Vs Z790

Intel’s Z chipsets have all the bells and whistles. This is an important thing to know about these chipsets. So, any Z chipset will come with many top-of-the-line features for connectivity, speed, and overclocking when it is made.

In the same way, the last-generation Z690 chipset had a lot of features, such as support for next-generation DDR5 memory and many USB ports and PCIe lines, that are still very much in use here.

Since the 13th-generation Raptor Lake design is part of Intel’s “tock” phase, there are also no significant changes. Even when we compared the i9-13900K to the i9-12900K, we saw that the 13th-gen CPU was better, but it only ran about 13.4% faster than the 12th-gen CPU.

The Z790 chipset is meant to be an improved version of the one that came before, not a complete redesign with new technologies. Because everything has stayed the same, older 600-series motherboards can still work with Raptor Lake CPUs. With a BIOS update, you can use the top-of-the-line Core i9-13900K with your Z690 processor.

Z790 Vs. Z690: Key Differences

Let’s talk about what makes them different.

Revised PCIe Lanes And An Extra USB Port

So, if you compare their specs, you will see that a lot has stayed the same. Both boards use the same LGA 1700 chip and have many of the same features. Overall, the Z790 is the “tock,” while the Z690 was the “tick.”

The main changes in the Z790 processors are two small ones. First, you get an extra USB 3.2 Gen 22 20 GB/s port, making the total number of 20 GB/s ports 5, up from 4 on Z690 motherboards.

Second, both motherboards have the same number of PCI express lanes, which is 28. However, how they are set up has been slightly changed to improve connection.

From 16 in Z690 to 8 in Z790, the overall number of PCIe 3.0 lanes has been cut in half. On the other hand, the number of PCIe 4.0 lanes has increased from 12 in the Z690 to 20 in the Z790. This gives you more ways to join.

Since all PCI Express lanes were moved, the number of M.2 slots has also increased. Now, a Z790 motherboard can support up to five M.2 slots, while the Z690 motherboard from the previous generation could only support up to four.

Higher DDR5 Speeds

The Z790 and the Z690 support DDR5 memory, but unlike AMD’s AM5 socket, which only supports DDR5 memory, Intel is set to keep DDR4 support until 2024.

In terms of DDR5 memory speeds, however, there is a slight change between the two motherboards. Even though both the Z790 and the Z690 can use DDR4 memory with transfer speeds of up to 3200 MT/s, the Z690 can only use DDR5 memory with transfer speeds of up to 4800 MT/s.

On the other hand, the latest Z790 allows up to 5600 MT/s DDR5 memory transfer rates. You can learn the difference between DDR4 and DDR5 RAM by reading our guide on DDR4 vs DDR5.

Should You Upgrade To The Z790?

We’ve already seen that the two systems are similar. Z690 and Z790 are the same, except that the PCIe lines have been moved, and the DDR5 memory clock speed is a bit faster.

So, if you don’t care about the few changes that come with the Z790, you can use the Z690 without any problems. A motherboard from the last generation will also be easy on your pocket.
