Hello everyone, in this lesson we will talk about the video memory in the discrete graphics card

2

00:00:07,000 --> 00:00:12,100

The function of the video memory is similar to that of the memory.

3

00:00:12,733 --> 00:00:19,633

The video memory is used to temporarily store the data in the GPU operation, before and after the operation.

4

00:00:20,066 --> 00:00:27,833

There are currently four commonly used video memory versions, namely DDR5, DDR5X, DDR6 and DDR6X

5

00:00:30,533 --> 00:00:34,766

The X at the end represents the low voltage version

6

00:00:35,766 --> 00:00:41,400

The low-voltage version is generally used on higher-end graphics cards of the same series

7

00:00:42,166 --> 00:00:46,133

For example, 1060, it uses DDR5 video memory

8

00:00:47,133 --> 00:00:51,966

And 1080TI, it uses DDR5X video memory

9

00:00:52,666 --> 00:00:58,533

At the same time, the graphics card determines the performance of the graphics card to a certain extent.

10

00:00:59,166 --> 00:01:05,333

In the case of the same core, the larger the memory, the better the performance of the graphics card

11

00:01:06,700 --> 00:01:10,533

Video memory is also a very high-tech product

12

00:01:11,366 --> 00:01:19,466

At present, the video memory on the graphics card we buy is produced by Samsung, Hynix, Micron, and Elpida.

13

00:01:21,500 --> 00:01:26,100

Next, let's take a look at these four video memory

14

00:01:26,100 --> 00:01:33,266

They are relatively easy to distinguish in appearance, and they all have their own LOGO on the memory.

15

00:01:33,966 --> 00:01:39,933

Such as Samsung's LOGO, Micron's LOGO, Hynix's LOGO, Elpida's LOGO

16

00:01:41,333 --> 00:01:45,066

And the video memory also has a code

17

00:01:45,600 --> 00:01:48,533

Different codes represent different video memory

18

00:01:49,100 --> 00:01:54,500

For example, Samsung's video memory, the entire second row is its code name

19

00:01:55,200 --> 00:01:58,666

Micron's video memory code is also in the second row

20

00:01:59,700 --> 00:02:05,766

Hynix's video memory code name is the second row plus the first three letters in the third row

21

00:02:07,466 --> 00:02:12,666

The code names of Elpida's video memory are the second row and the third row
