1
00:00:00,120 --> 00:00:07,080
whenever there's a big new graphics card release there's always like a feeding

2
00:00:04,319 --> 00:00:11,679
frenzy as Gamers try to get their hands on it so that they can blow away dudes

3
00:00:09,320 --> 00:00:16,199
in crisper detail and at higher resolutions than ever before but while

4
00:00:14,320 --> 00:00:22,199
the performance of the graphics processor or GPU itself is often the

5
00:00:19,480 --> 00:00:28,000
most talked about aspect of a new card the amount of video memory or vram on a

6
00:00:25,240 --> 00:00:33,440
card can have a big effect on just how high you can crank up your settings

7
00:00:30,519 --> 00:00:38,559
but while gpus or Graphics processors have been updated and re-updated pretty

8
00:00:36,160 --> 00:00:44,360
regularly over the last few years not much has happened with vram recently

9
00:00:41,239 --> 00:00:47,280
we've had the same old gddr5 memory

10
00:00:44,360 --> 00:00:53,359
hanging out on our cards for over seven years but the next big thing in vram is

11
00:00:50,920 --> 00:00:58,640
finally here I'm talking of course about high bandwidth memory or hbm so what

12
00:00:56,760 --> 00:01:03,079
exactly is it how is it better than older vram technology and most

13
00:01:00,760 --> 00:01:08,680
importantly is it actually going to make a difference in your games well just

14
00:01:06,040 --> 00:01:13,439
like any other type of vram hbm performs functions like keeping rendered frames

15
00:01:10,759 --> 00:01:18,479
in storage in a frame buffer no not that kind holding textures to make everything

16
00:01:15,799 --> 00:01:23,320
on screen look realistic and storing crucial information for lighting and

17
00:01:20,680 --> 00:01:27,960
other effects in short it holds the information that your GPU needs to act

18
00:01:25,600 --> 00:01:32,600
upon to push an image to your monitor but although hbm serves the same base

19
00:01:29,920 --> 00:01:37,560
basic function as other types of vram the way that it's actually implemented

20
00:01:34,720 --> 00:01:45,079
on your graphics card is very different for starters gddr5 and its predecessors

21
00:01:40,759 --> 00:01:48,040
require dram chips attached to the PCB

22
00:01:45,079 --> 00:01:52,399
spread out around the processor and the more memory you want and the higher

23
00:01:49,880 --> 00:01:57,680
speeds you want the more chips you need to plunk on there which combined with

24
00:01:54,759 --> 00:02:02,280
the traces for data and power to all those chips take up a lot of space on

25
00:01:59,560 --> 00:02:08,640
the car hard and increased manufacturing complexity and therefore cost hbm solves

26
00:02:05,920 --> 00:02:14,120
these problems two ways number one the vram is now directly attached to the GPU

27
00:02:11,560 --> 00:02:20,879
package meaning that hbm requires no more space than what's already normally

28
00:02:16,200 --> 00:02:23,160
taken up by the GPU two hbm uses 3D RAM

29
00:02:20,879 --> 00:02:28,720
dieses that are stacked on top of each other and that communicate using tiny

30
00:02:25,840 --> 00:02:33,120
interconnects called through silicon vas or tsvs which are called that since they

31
00:02:31,319 --> 00:02:38,319
physically go through all the Stacked layers at once kind of like a toothpick

32
00:02:35,760 --> 00:02:42,560
through a giant club sandwich and while you can't eat hbm like you would a Monte

33
00:02:40,400 --> 00:02:47,480
Christo these changes have the potential to give you some positively delicious

34
00:02:44,920 --> 00:02:51,800
results while gaming so the chips themselves have a much wider data

35
00:02:49,120 --> 00:02:57,319
interface that combined with stacking the chips gives you these little well

36
00:02:54,280 --> 00:02:59,360
Stacks that can move up to 256 gabt of

37
00:02:57,319 --> 00:03:03,599
data per second which means that a graphics card with just four stacks of

38
00:03:01,200 --> 00:03:08,959
hbm could have memory throughput of a full terabyte of data per second which

39
00:03:07,040 --> 00:03:13,280
will become increasingly important in the future as more and more non-gaming

40
00:03:11,480 --> 00:03:18,000
applications like Adobe Premiere for example start leveraging the graphics

41
00:03:15,159 --> 00:03:22,080
card for compute and as the resolutions that typical Gamers want to run at

42
00:03:20,440 --> 00:03:27,599
increase not to mention that there's things like multi 4k monitor setups that

43
00:03:24,519 --> 00:03:29,760
are becoming cheaper and more popular

44
00:03:27,599 --> 00:03:36,040
all of which will be easier with more memory bandwidth okay then lonus so how

45
00:03:32,480 --> 00:03:38,760
do I hop on board this hype train well

46
00:03:36,040 --> 00:03:43,879
hbn is only currently available on AMD's topend Radeon R9 Fury series but the

47
00:03:42,120 --> 00:03:48,239
rumor mill figures that NVIDIA's upcoming Pascal graphics cards will

48
00:03:45,959 --> 00:03:51,480
feature the technology and as we all know the high-end today is the

49
00:03:49,640 --> 00:03:56,040
mainstream of tomorrow so within a couple years we should all be able to

50
00:03:53,319 --> 00:04:02,680
have enough memory bandwidth to choke a horse speaking of choking horses or nope

51
00:04:00,519 --> 00:04:06,920
not related to that at all Dollar Shave Club you can get razors and other

52
00:04:04,840 --> 00:04:11,480
bathroom supplies shipped directly to your door for only a few bucks a month

53
00:04:09,000 --> 00:04:16,759
they've got their razor handles and blade combos all the way up to the like

54
00:04:13,799 --> 00:04:20,759
six blade executive but with that said they don't go overboard and kind of go

55
00:04:19,040 --> 00:04:25,280
yeah well this one's got like a rear view mirror and a vibrating handle that

56
00:04:23,280 --> 00:04:28,880
you can use for all kinds of oh right they also have other products like their

57
00:04:26,880 --> 00:04:33,199
one wipe Charlie's peppermint scented butt wipes from their post shave

58
00:04:30,880 --> 00:04:37,759
moisturizer and their Dr Carver shave butter which goes on clear so you can

59
00:04:35,240 --> 00:04:41,639
actually see what you're doing I mean I guess it's pretty

60
00:04:39,720 --> 00:04:45,919
straightforward isn't it high quality razors and bathroom supplies directly to

61
00:04:43,600 --> 00:04:49,360
your door once a month for a few bucks a month visit

62

dollarshaveclub.com Linus to join the club now it's available in the US Canada

63
00:04:51,880 --> 00:04:57,160
and Australia all right so thanks for watching guys if you like the video do
