00:00:00.080 --> 00:00:06.240
upgrading your main system memory is a piece of cake you buy a ddr module you

00:00:04.080 --> 00:00:10.559
slot it in and enjoy but have you ever wondered why you can't

00:00:08.160 --> 00:00:15.040
do that with video RAM on your graphics card this is a fair question especially

00:00:12.400 --> 00:00:19.840
considering how much vram modern games can require you see vram stores textures

00:00:17.680 --> 00:00:24.400
and other visual assets that the GPU processes in order to render all those

00:00:21.920 --> 00:00:28.960
lovely frames that appear on your screen and as games have gotten more advanced

00:00:26.160 --> 00:00:32.640
these visual assets take up lots of room especially if you're gaming at high

00:00:30.240 --> 00:00:37.440
resolutions or high settings and not only that but because of how fast your

00:00:34.880 --> 00:00:44.360
GPU has to spit out all those frames it needs access to the information in vram

00:00:40.239 --> 00:00:44.360
oh boy very quickly

00:00:44.559 --> 00:00:50.960
additionally graphics rendering is a highly parallelized process

00:00:49.200 --> 00:00:55.440
which means your GPU's architecture is built to work on several data streams at

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

00:00:57.680 --> 00:01:06.000
has a lot more bandwidth than your main system RAM for example a one Gigabyte

00:01:03.320 --> 00:01:12.400
gddr6x chip has a transfer rate of around 84 gigabytes per second compared

00:01:08.560 --> 00:01:14.640
to ddr4 3200 which is only about 26

00:01:12.400 --> 00:01:18.880
gigabytes per second all the speed is actually a huge reason why you can't

00:01:16.400 --> 00:01:23.680
just add more vram you see the high bandwidth necessitates a large number of

00:01:21.200 --> 00:01:28.479
physical connections for example think about how many pins your CPU uses to

00:01:26.240 --> 00:01:32.960
both move data and ensure it has a sufficiently stable power supply to do

00:01:30.479 --> 00:01:36.960
so but there's only so much room on a typical graphics card so instead of

00:01:34.720 --> 00:01:41.600
having a big old socket like motherboards do manufacturers instead

00:01:39.280 --> 00:01:46.399
solder vram modules directly to the graphics card pcb to save space and some

00:01:44.159 --> 00:01:51.119
types of video memory such as hbm are actually combined on the same package as

00:01:48.720 --> 00:01:55.840
the GPU itself not only does this take up less real estate but it also cuts

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

00:01:58.000 --> 00:02:04.159
speeds introduces the possibility of errors kind of like how trying to type

00:02:02.399 --> 00:02:08.319
really fast means that you're likely to make more spelling mistakes soldering

00:02:06.079 --> 00:02:12.319
vram chips directly on the board and integrating them tightly with a GPU is

00:02:10.560 --> 00:02:17.280
not only cheaper than engineering a socket or slot that an end user can add

00:02:14.640 --> 00:02:21.920
vram to but it also removes a layer of complexity that could result in more

00:02:19.760 --> 00:02:25.599
data errors although there were some older graphics cards from way back in

00:02:23.760 --> 00:02:29.680
the day where you could slot in more vram the amount of speed you need these

00:02:27.840 --> 00:02:34.239
days means it just isn't practical anymore and even if you just tried to

00:02:32.080 --> 00:02:39.040
solder a higher capacity vram chip onto your graphics card there's a chance

00:02:36.959 --> 00:02:42.400
a pretty high chance it wouldn't work due to the card's firmware being

00:02:40.480 --> 00:02:46.319
specifically tuned for the vram configuration it's shipped with not to

00:02:44.720 --> 00:02:51.440
mention you'd probably end up breaking your expensive GPU so just i wouldn't

00:02:48.800 --> 00:02:55.440
risk it but even though games are requiring more vram than ever the

00:02:53.280 --> 00:03:00.239
culprit of poor performance is much more often an underpowered GPU rather than

00:02:58.239 --> 00:03:04.080
insufficient vram so if you're having weird slowdowns or crashes in a game

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

00:03:06.959 --> 00:03:12.879
rather than just more vram and if you're using an integrated GPU not a discrete

00:03:11.280 --> 00:03:18.000
graphics card like this one those solutions actually use part of your main

00:03:15.280 --> 00:03:21.599
system memory as vram so if you find yourself running low you can go into

00:03:19.760 --> 00:03:25.280
your computer's BIOS and increase the amount that's allocated for video memory

00:03:23.680 --> 00:03:29.440
man if only it were possible to just download more vram like you can with

00:03:26.800 --> 00:03:33.040
regular RAM it'll be so much easier big thanks to bitdefender for sponsoring
