00:00:00,080 --> 00:00:06,240
upgrading your main system memory is a piece of cake you buy a ddr module you

2
00:00:04,080 --> 00:00:10,559
slot it in and enjoy but have you ever wondered why you can't

3
00:00:08,160 --> 00:00:15,040
do that with video RAM on your graphics card this is a fair question especially

4
00:00:12,400 --> 00:00:19,840
considering how much vram modern games can require you see vram stores textures

5
00:00:17,680 --> 00:00:24,400
and other visual assets that the GPU processes in order to render all those

6
00:00:21,920 --> 00:00:28,960
lovely frames that appear on your screen and as games have gotten more advanced

7
00:00:26,160 --> 00:00:32,640
these visual assets take up lots of room especially if you're gaming at high

8
00:00:30,240 --> 00:00:37,440
resolutions or high settings and not only that but because of how fast your

9
00:00:34,880 --> 00:00:44,360
GPU has to spit out all those frames it needs access to the information in vram

10
00:00:40,239 --> 00:00:44,360
oh boy very quickly

11
00:00:44,559 --> 00:00:50,960
additionally graphics rendering is a highly parallelized process

12
00:00:49,200 --> 00:00:55,440
which means your GPU's architecture is built to work on several data streams at

13
00:00:53,440 --> 00:01:00,079
once you can learn more about that right up here but the bottom line is that vram

14
00:00:57,680 --> 00:01:06,000
has a lot more bandwidth than your main system RAM for example a one Gigabyte

15
00:01:03,320 --> 00:01:12,400
gddr6x chip has a transfer rate of around 84 gigabytes per second compared

16
00:01:08,560 --> 00:01:14,640
to ddr4 3200 which is only about 26

17
00:01:12,400 --> 00:01:18,880
gigabytes per second all the speed is actually a huge reason why you can't

18
00:01:16,400 --> 00:01:23,680
just add more vram you see the high bandwidth necessitates a large number of

19
00:01:21,200 --> 00:01:28,479
physical connections for example think about how many pins your CPU uses to

20
00:01:26,240 --> 00:01:32,960
both move data and ensure it has a sufficiently stable power supply to do

21
00:01:30,479 --> 00:01:36,960
so but there's only so much room on a typical graphics card so instead of

22
00:01:34,720 --> 00:01:41,600
having a big old socket like motherboards do manufacturers instead

23
00:01:39,280 --> 00:01:46,399
solder vram modules directly to the graphics card pcb to save space and some

24
00:01:44,159 --> 00:01:51,119
types of video memory such as hbm are actually combined on the same package as

25
00:01:48,720 --> 00:01:55,840
the GPU itself not only does this take up less real estate but it also cuts

26
00:01:53,280 --> 00:02:00,159
down on the risk of data errors you see moving all that data around at such high

27
00:01:58,000 --> 00:02:04,159
speeds introduces the possibility of errors kind of like how trying to type

28
00:02:02,399 --> 00:02:08,319
really fast means that you're likely to make more spelling mistakes soldering

29
00:02:06,079 --> 00:02:12,319
vram chips directly on the board and integrating them tightly with a GPU is

30
00:02:10,560 --> 00:02:17,280
not only cheaper than engineering a socket or slot that an end user can add

31
00:02:14,640 --> 00:02:21,920
vram to but it also removes a layer of complexity that could result in more

32
00:02:19,760 --> 00:02:25,599
data errors although there were some older graphics cards from way back in

33
00:02:23,760 --> 00:02:29,680
the day where you could slot in more vram the amount of speed you need these

34
00:02:27,840 --> 00:02:34,239
days means it just isn't practical anymore and even if you just tried to

35
00:02:32,080 --> 00:02:39,040
solder a higher capacity vram chip onto your graphics card there's a chance

36
00:02:36,959 --> 00:02:42,400
a pretty high chance it wouldn't work due to the card's firmware being

37
00:02:40,480 --> 00:02:46,319
specifically tuned for the vram configuration it's shipped with not to

38
00:02:44,720 --> 00:02:51,440
mention you'd probably end up breaking your expensive GPU so just i wouldn't

39
00:02:48,800 --> 00:02:55,440
risk it but even though games are requiring more vram than ever the

40
00:02:53,280 --> 00:03:00,239
culprit of poor performance is much more often an underpowered GPU rather than

41
00:02:58,239 --> 00:03:04,080
insufficient vram so if you're having weird slowdowns or crashes in a game

42
00:03:02,319 --> 00:03:09,200
you're playing do a bit of research and see if you really need a higher tier GPU

43
00:03:06,959 --> 00:03:12,879
rather than just more vram and if you're using an integrated GPU not a discrete

44
00:03:11,280 --> 00:03:18,000
graphics card like this one those solutions actually use part of your main

45
00:03:15,280 --> 00:03:21,599
system memory as vram so if you find yourself running low you can go into

46
00:03:19,760 --> 00:03:25,280
your computer's BIOS and increase the amount that's allocated for video memory

47
00:03:23,680 --> 00:03:29,440
man if only it were possible to just download more vram like you can with

48
00:03:26,800 --> 00:03:33,040
regular RAM it'll be so much easier big thanks to bitdefender for sponsoring
