Ports and Compatibility

A key difference between B660 and Z690 motherboards lies in the ports. Z690 is an advanced motherboard with much better support for PCIe lines. The motherboard features 16 PCIe slots which are suitable for a 2×8 configuration. It’s also worth mentioning that the Z690 provides support for both PCIe 4.0 and 3.0 lanes. However, the B660 motherboard features only support for PCIe 4.0 lanes, so if you plan on installing dual GPU, you’ll have more versatility with the Z690 motherboard.

Also, the Z690 motherboard is a lot more efficient. You can get much higher graphical power with more versatile combinations, especially if you plan on executing two graphics cards in combination.

From other ports, it’s worth mentioning that both motherboards support DMI 4.0 version and that Z690 supports eight lanes while B660 supports only four lanes. Both motherboards come with integrated data protection (RAID support), but while Z690 provides RAID support for SATA and PCIe, B660 only provides RAID support for SATA. This means you’ll have much better data protection with the Z690 motherboard.

Z690 also has more USB ports (x14), while B660 has only 12 USB ports. Ports range in versions but it’s safe to say that both motherboards cover a great range of USB port versions so you won’t ever lack higher-speed ports.

Overclocking Support

Z690 motherboard provides overclocking support, and it’s advertised as a motherboard that supports CPU and memory overclocking. Overclocking maximizes the CPU or memory by pushing its limits a bit over the edge. It isn’t harmful as long as all components, including the motherboard, CPU, and memory, support it.

Z690 is ideal for use with overclockable CPUs such as the Unlocked K series. On the other hand, B660 doesn’t officially support overclocking, but it might support overclocking, but it’s unknown how harmful that might be to the motherboard. Therefore, if you plan on overclocking your components, the Z690 motherboard is the motherboard to use, and this is something it’s good to know up-front.

However, keep in mind that most newer powerful components might not require the extra boost by overclocking as they’re already powerful enough, so B660 is still a good choice after all. It all depends on your purpose and how you will use your computer once you choose all the components and build it.

Integrated Graphics Card and Memory

Both B660 and Z690 support integrated graphics. While they provide similar quality, Z690 is slightly better since it’s a bit more advanced. It could provide a bit more power and performance, but you can overlook this if you plan on using a dedicated graphics card.

On the other hand, while both motherboards support DDR4 and DDR5 memory types, Z690 operates better with the DDR5 memory type because it supports a clock speed of up to 4800MHz for the DDR5 type. It’s also worth mentioning that using DDR4 memory type with a Z690 motherboard will only get you a clock speed of up to 3200MHz. And on top of that, you should consider the overclocking capability of the Z690 motherboard, which is another advantage over the B660 motherboard.

The B660 motherboard works equally well with both DDR4 and DDR5 memory types, with slight differences between the clock speed. Z690 is a slightly better choice if you’ll use the DDR5 memory type. On top of that, B660 doesn’t support memory overclocking, which is worth considering if you plan on using the overclocking feature.

Both motherboards have the same number of channels. They also support up to 128GB RAM and have four slots.

Support and Additional Integrations

B660 and Z690 support up to 4 additional displays and come with an integrated WiFi 6E adapter. When it comes down to thermal design power, both B660 and Z690 support 6W. These motherboards support the 12th generation of Intel processors and are pretty much similar in all other aspects. However, a couple of differences can add up and can make one motherboard a better fit for your needs.


Twice as expensive as the B660, the Z690 motherboard comes with a lot more advanced features, and it’s a much better fit for higher-end builds, such as gaming computers. B660 is a lot more affordable, but it can lack certain features you might require if you are doing a high-end build. But if you don’t need those features, you will be able to use a B660 motherboard to build an intermediate computer ideal for a variety of tasks.

Also, keep in mind that Z690 comes in a couple of versions. Depending on the features you need, such as the DDR5 support, you might have to pay a bit more for the version that supports one or more higher-end features.
