How does this board look at the north-south bridge and how to identify it?

Notebook motherboard parts are generally many, and the North Bridge and graphics card are generally arranged near the CPU.

Here is the North Bridge above, the brand logo in the middle, the graphics card chip below, and two memory particle chips next to it.

The south bridge should be on the back.

North-South Bridge is a chip structure, and North-South Bridge structure is a very popular motherboard chipset structure with a long history. There are two large-area chips on the main board of the north-south bridge structure. Northbridge chip near CPU is mainly responsible for controlling the data exchange between AGP graphics card, memory and CPU. Near the PCI slot is the south bridge chip, which is mainly responsible for data exchange of floppy drive, hard disk, keyboard and add-on card. The traditional north-south bridge architecture is connected by PCI bus. The commonly used PCI bus has a working frequency of 33.3MHz and a transmission width of 32bit, so the theoretical maximum data transmission rate is only 133MB/s/s ... Due to the sharing of PCI bus, when the transmission rate of subsystems and other peripheral devices is continuously improved, the low data transmission rate between the north and south bridges of the motherboard gradually becomes a bottleneck affecting the overall performance of the system. Therefore, from Intel i8 10, chipset manufacturers began to seek a solution that can increase the bandwidth of the North-South Bridge connection.

South bridge SB and north bridge NB

North bridge generally has a heat sink, not far from CPU.

Generally, the south bridge has no fins, so it is easy to find.
