Z690 vs Z790 – Which to Choose?

With the launch of 13th Gen Core processors, Intel also released a new top end chipset – the Z790. But how do these new motherboards compare to the previous Gen Z690 and which should you use for your next gaming pc or workstation build? Read on to learn more on Z690 vs Z790.

What is Z790 (…and what’s a chipset)?

Z690 vs Z790

A chipset is a component on a motherboard that’s designed by Intel or AMD to work exclusively with their specific processors and essentially facilitates communication between the CPU, storage, RAM, GPU, and I/O. Certain chipsets only support certain features such as PCIe Gen 5, DDR5 RAM, USB 3.2 Gen 2, etc. Specific chipsets also only support specific processors, so when choosing a motherboard, make sure that the included chipset supports your processor of choice.

Z790 is the Intel chipset that supports 12th and 13th Gen Intel Core processors (ie. Core i5-12600k, i9-13900k, etc). It uses the same LGA 1700 socket as the preceding gen Z690, but includes a few additional features that chipset does not. But are those additional features worth it?

Z690 vs Z790 – How do Features Compare?

Z690 Z790
Intel Socket LGA 1700 LGA 1700
12th Gen Support Yes Yes
13th Gen Support Yes (with BIOS update) Yes
Support Overclocking Yes Yes
Max RAM speed 6400 6800
Max RAM Capacity 128GB 128GB
Total PCIe Lanes 28 28
PCIe Gen 5 Lanes 20 20
PCIe Configurations 1×16+1×4 or 2×8+1×4 1×16+1×4 or 2×8+1×4
Max USB 3.2 Gen 2×2 Ports 4 5
Max USB 3.2 Gen 2×1 Ports 10 10
Max USB 3.2 Gen 1×1 Ports 10 10
Max USB 2.0 Ports 14 14

As you can see, with a few minor exceptions, the two chipsets are extremely similar in terms of features. One additional notable difference is that because of the additional available I/O throughput of Z790, those boards are more likely to have Thunderbolt 4/USB 4 ports, though both chipsets technically support them.


We’ve tested and retested both 12th Gen and 13th Gen processors on Z690 and Z790 chipset boards. But did we find any notable performance difference?


It’s much more likely you’ll see bigger variations processor to processor than you will between two identical motherboard models with differing chipsets. Don’t make this choice based on performance.

Which to choose?

Given the nearly identical feature set and the actually identical performance, it’s hard to justify paying a premium for Z790 over Z690 in all but the absolute highest end builds. Unless you feel the need for Thunderbolt 4 (and can’t find a Z690 board that supports it) or have some DDR5-6800 RAM that needs a home, Z690 is likely the best choice for your next build.
