MB : Real difference between Z690 and B660?

[Natsukashii]

I am planning my next build and I have two motherboards in mind :

ROG STRIX Z690-A GAMING WIFI D4

https://rog.asus.com/fr/motherboards/rog-strix/rog-strix-z690-a-gaming-wifi-d4-model/
and

ROG STRIX B660-A GAMING WIFI D4

https://rog.asus.com/motherboards/rog-strix/rog-strix-b660-a-gaming-wifi-d4-model/

 

I have already 2 sata SSD, 2 sata HDD, I plan to add/replace with 2 or 3 nvme SSD
I don't think I would feel having gen 4 nvme SSD since I'm already fine with my sata SSD so I don't mind having nvme gen 3.

Planned cpu I7 12700k paired with 4x8 DDR4

 

I tend to overclock cpu/ram down the line when I feel I need to stretch a bit more live out of the build, my first pc lasted 5 years, current one is starting its 4th year.

What are the real difference between both motherboards aside from the look?

Overclocking.

the z has it, the b doesnt

plus theres more conectivity iirc on the z

oh so the b660 would go with a 12700 and the 2 with the K variant, ok got it thanks!

yes, though both cpus work on both motherboards, but only a z series with a k varient can overclock (though a non k cpu may be able to be blck oced with a z series)

OC'ing and the Z board has more I/O for stuff like USB. So a Z board might have more, of faster USB ports.

The K series boards will be designed with overclocking in mind as well as having better connectivity. If you are going with a 12700K you’d be better off with a Z690 especially if you want to overclock.
