Let's begin with the H670 chipset, which sits one step below Z690. Most of the core functionality remains the same, including DDR4 and DDR5 support. The H670 chipset lacks the ability to overclock the CPU, which is difficult anyway unless you have very good cooling. Thankfully, H670 retains the ability to overclock the memory. The DMI link remains at 8x, meaning it will be possible for manufacturers to make H670 boards with up to four or five M.2 slots.

The USB count is the disappointing part as the H670’s USB 3.0 count is lacking compared to Z690. Of course, thanks to a high number of chipset PCIe lanes, board manufacturers are free to include auxiliary USB controllers. Some H670 boards are likely to be priced at pretty steep levels making them strong entry/mid range Z690 competitors.

B660 is the chipset that most DIY’ers on a budget will look at. Compared to Z690 it loses the ability to overclock the CPU, while retaining memory OC capabilities. It includes only one PCIe 5.0 slot, which at this point in time means very little—it's possible PCIe 5.0 support will be optional or limited to high end models. The DMI link drops to 4x, half that of Z690 and H670, so board makers are unlikely to include more than two or three M.2 slots. The USB count drops only a little from H670.
