Southbridge of this motherboard

[z077]

Hello, I can't find what is the model of the southbridge of this motherboard or maybe there isn't.
I found the northbridge but the southbridge is not specified in the motherboard's user manual.

The motherboard is this, https://www.gigabyte.com/Motherboard/GA-H170-D3HP-rev-10#ov

Regards.

the southbridge of the motherboard was moved to the CPU years ago in both AMD and Intel systems. the memory controller integrated graphics controllers and other components that make up the SB are now part of the CPU.
the CPU is the southbridge

There is no Southbridge. The old Northbridge-Southbridge combination has been abolished and moved to chipsets. Most of the duties of the Southbridge are part of the CPU, the others alongside the Northbridge have been moved to the chipset - in this case H170
