Hello everyone, today we will learn about the Intel 8 series chipset motherboard architecture diagram

2

00:00:07,566 --> 00:00:12,000

This is an Intel 8 series chipset motherboard architecture diagram

3

00:00:12,400 --> 00:00:14,633

In this architecture diagram

4

00:00:14,900 --> 00:00:16,500

This is PCH

5

00:00:16,933 --> 00:00:21,100

In reality, PCH is a chip like this

6

00:00:21,833 --> 00:00:25,266

This PCH model is HM87

7

00:00:25,733 --> 00:00:28,266

Belongs to Intel 8 series chipset

8

00:00:28,733 --> 00:00:32,266

It is paired with the 4th and 5th generation CPUs

9

00:00:32,766 --> 00:00:37,633

It manages discrete graphics via PCIE x16 bus

10

00:00:38,166 --> 00:00:40,466

It's also known as GPU

11

00:00:41,300 --> 00:00:44,166

Discrete graphics card requires video memory

12

00:00:44,533 --> 00:00:47,366

This VRAM refers to the video memory

13

00:00:48,066 --> 00:00:51,966

CPU can directly output eDP (Embedded DisplayPort) display signal

14

00:00:52,566 --> 00:00:54,600

It's to the screen interface

15

00:00:55,466 --> 00:00:58,466

DDI (Digital Display Interface) bus is a digital display port

16

00:00:59,000 --> 00:01:03,666

The output display signal is given to the HDMI interface

17

00:01:04,233 --> 00:01:07,733

The CPU also manages DDR3L memory

18

00:01:08,300 --> 00:01:15,466

The communication bus between CPU and PCH still retains FDI bus and DMI bus

19

00:01:16,233 --> 00:01:20,000

FDI bus is used to transmit display signals

20

00:01:20,400 --> 00:01:25,533

It is a one-way transmission, sent by the CPU to the PCH

21

00:01:26,200 --> 00:01:30,066

Display signal is mainly used for CRT interface

22

00:01:30,433 --> 00:01:40,966

All data between the CPU and PCH except the display signal is transmitted through the DMI bus, which is bidirectionally transmitted

23

00:01:41,566 --> 00:01:45,533

PCH manages the sound card chip through the HDA bus (sound card bus)

24

00:01:46,300 --> 00:01:52,233

The sound card chip is connected to the microphone interface and the headphone interface, etc.

25

00:01:52,766 --> 00:02:00,200

PCH manages two USB interfaces via USB 3.0 bus, USB 2.0 bus

26

00:02:00,600 --> 00:02:01,500

and camera

27

00:02:02,333 --> 00:02:05,333

PCH reads BIOS via SPI bus

28

00:02:05,633 --> 00:02:09,366

PCH communicates with EC via LPC bus

29

00:02:09,566 --> 00:02:12,333

EC manages the keyboard and touchpad

30

00:02:13,800 --> 00:02:18,566

As well as temperature control circuit, charging circuit and battery

31

00:02:19,200 --> 00:02:24,900

PCh is connected to the solid state drive (SSD) of the mSATA interface through the SATA bus

32

00:02:25,833 --> 00:02:28,033

It manages (HDD) hard drives

33

00:02:28,666 --> 00:02:32,133

PCH also manages WIFI (wireless network card) through PCIE bus

34

00:02:34,433 --> 00:02:37,700

Bluetooth uses USB 2.0 bus

35

00:02:38,033 --> 00:02:42,300

The PCH also manages the network card through the PCIE bus

36

00:02:42,800 --> 00:02:46,366

This "RJ45" refers to the network cable interface

37

00:02:46,700 --> 00:02:51,600

PCH manages the card reader over the USB 3.0 bus

38

00:02:51,733 --> 00:02:55,100

Well, this is the Intel 8 series chipset architecture
