Hello everyone, let's learn about the Intel 400 series chipset architecture

2

00:00:05,466 --> 00:00:11,233

This is an Intel 400 series chipset architecture diagram of a notebook motherboard

3

00:00:11,900 --> 00:00:17,900

This PCH (chip) model is HM470, which belongs to the Intel 400 series

4

00:00:17,900 --> 00:00:20,133

In reality it's like this

5

00:00:21,200 --> 00:00:23,900

It's paired with a 10th generation processor

6

00:00:24,133 --> 00:00:26,766

The 10th generation processor is like this

7

00:00:26,800 --> 00:00:31,233

CPU still manages the discrete graphics card through the PCIE bus

8

00:00:31,666 --> 00:00:35,066

CPU internal integrates graphics card function

9

00:00:35,266 --> 00:00:39,300

DP signal output by CPU to MINI DP interface

10

00:00:39,466 --> 00:00:45,800

At the same time, it will also output eDP signal to the screen interface for LCD display

11

00:00:46,366 --> 00:00:51,000

CPU also manages the discrete graphics card through the PCIE bus

12

00:00:51,366 --> 00:00:56,033

The signal of the HDMI interface is output by the discrete graphics card

13

00:00:56,300 --> 00:01:00,300

CPU communicates with DDR4 (4th generation memory) memory through memory bus

14

00:01:00,900 --> 00:01:05,900

The communication bus between CPU and PCH is still DMI bus

15

00:01:06,466 --> 00:01:11,800

PCH can manage external devices of USB interface through USB bus

16

00:01:13,700 --> 00:01:19,200

PCH manages Type-C interface via USB 3.1 bus

17

00:01:19,566 --> 00:01:23,100

PCH manages TPM (Security Chip) via SPI bus

18

00:01:26,400 --> 00:01:30,266

PCH communicates with EC via LPC bus

19

00:01:31,733 --> 00:01:34,466

EC manages the touchpad and keyboard

20

00:01:35,566 --> 00:01:39,766

At the same time,EC also manages the temperature control circuit

21

00:01:40,066 --> 00:01:44,433

It also manages fans, as well as adapter and battery information

22

00:01:45,033 --> 00:01:47,666

PCH reads BIOS via SPI bus

23

00:01:48,833 --> 00:01:52,033

PCH manages hard disk (HDD) via SATA bus

24

00:01:52,300 --> 00:01:58,100

It manages cameras, digital microphones via USB 2.0 bus

25

00:01:58,466 --> 00:02:06,466

At the same time, the USB 2.0 bus and the USB 3.0 bus go to the USB 3.0 interface at the same time

26

00:02:07,400 --> 00:02:10,666

PCIE bus goes to NGFF interface

27

00:02:10,800 --> 00:02:15,066

NGFF interface can also be called M.2 interface

28

00:02:15,233 --> 00:02:17,300

This is for WiFi communication

29

00:02:17,566 --> 00:02:21,233

Bluetooth communicates via USB 2.0 bus

30

00:02:21,800 --> 00:02:25,133

CNVI bus is also used for WiFi module

31

00:02:25,800 --> 00:02:29,200

PCIE bus also manages the wired network card

32

00:02:29,600 --> 00:02:31,966

This card has a card reader function

33

00:02:32,200 --> 00:02:36,900

Manages a six-in-one card reader and a network cable interface

34

00:02:37,166 --> 00:02:41,366

PCH manages the sound card chip through the sound card bus

35

00:02:41,600 --> 00:02:46,633

The sound card manages the speakers and headphone and microphone interfaces

36

00:02:46,933 --> 00:02:50,833

Well, this is the Intel 400 series chipset architecture
