00:00:00.120 --> 00:00:07.080
whenever there's a big new graphics card release there's always like a feeding

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

00:00:09.320 --> 00:00:16.199
in crisper detail and at higher resolutions than ever before but while

00:00:14.320 --> 00:00:22.199
the performance of the graphics processor or GPU itself is often the

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

00:00:25.240 --> 00:00:33.440
card can have a big effect on just how high you can crank up your settings

00:00:30.519 --> 00:00:38.559
but while gpus or Graphics processors have been updated and re-updated pretty

00:00:36.160 --> 00:00:44.360
regularly over the last few years not much has happened with vram recently

00:00:41.239 --> 00:00:47.280
we've had the same old gddr5 memory

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

00:00:50.920 --> 00:00:58.640
finally here I'm talking of course about high bandwidth memory or hbm so what

00:00:56.760 --> 00:01:03.079
exactly is it how is it better than older vram technology and most

00:01:00.760 --> 00:01:08.680
importantly is it actually going to make a difference in your games well just

00:01:06.040 --> 00:01:13.439
like any other type of vram hbm performs functions like keeping rendered frames

00:01:10.759 --> 00:01:18.479
in storage in a frame buffer no not that kind holding textures to make everything

00:01:15.799 --> 00:01:23.320
on screen look realistic and storing crucial information for lighting and

00:01:20.680 --> 00:01:27.960
other effects in short it holds the information that your GPU needs to act

00:01:25.600 --> 00:01:32.600
upon to push an image to your monitor but although hbm serves the same base

00:01:29.920 --> 00:01:37.560
basic function as other types of vram the way that it's actually implemented

00:01:34.720 --> 00:01:45.079
on your graphics card is very different for starters gddr5 and its predecessors

00:01:40.759 --> 00:01:48.040
require dram chips attached to the PCB

00:01:45.079 --> 00:01:52.399
spread out around the processor and the more memory you want and the higher

00:01:49.880 --> 00:01:57.680
speeds you want the more chips you need to plunk on there which combined with

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

00:01:59.560 --> 00:02:08.640
the car hard and increased manufacturing complexity and therefore cost hbm solves

00:02:05.920 --> 00:02:14.120
these problems two ways number one the vram is now directly attached to the GPU

00:02:11.560 --> 00:02:20.879
package meaning that hbm requires no more space than what's already normally

00:02:16.200 --> 00:02:23.160
taken up by the GPU two hbm uses 3D RAM

00:02:20.879 --> 00:02:28.720
dieses that are stacked on top of each other and that communicate using tiny

00:02:25.840 --> 00:02:33.120
interconnects called through silicon vas or tsvs which are called that since they

00:02:31.319 --> 00:02:38.319
physically go through all the Stacked layers at once kind of like a toothpick

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

00:02:40.400 --> 00:02:47.480
Christo these changes have the potential to give you some positively delicious

00:02:44.920 --> 00:02:51.800
results while gaming so the chips themselves have a much wider data

00:02:49.120 --> 00:02:57.319
interface that combined with stacking the chips gives you these little well

00:02:54.280 --> 00:02:59.360
Stacks that can move up to 256 gabt of

00:02:57.319 --> 00:03:03.599
data per second which means that a graphics card with just four stacks of

00:03:01.200 --> 00:03:08.959
hbm could have memory throughput of a full terabyte of data per second which

00:03:07.040 --> 00:03:13.280
will become increasingly important in the future as more and more non-gaming

00:03:11.480 --> 00:03:18.000
applications like Adobe Premiere for example start leveraging the graphics

00:03:15.159 --> 00:03:22.080
card for compute and as the resolutions that typical Gamers want to run at

00:03:20.440 --> 00:03:27.599
increase not to mention that there's things like multi 4k monitor setups that

00:03:24.519 --> 00:03:29.760
are becoming cheaper and more popular

00:03:27.599 --> 00:03:36.040
all of which will be easier with more memory bandwidth okay then lonus so how

00:03:32.480 --> 00:03:38.760
do I hop on board this hype train well

00:03:36.040 --> 00:03:43.879
hbn is only currently available on AMD's topend Radeon R9 Fury series but the

00:03:42.120 --> 00:03:48.239
rumor mill figures that NVIDIA's upcoming Pascal graphics cards will

00:03:45.959 --> 00:03:51.480
feature the technology and as we all know the high-end today is the

00:03:49.640 --> 00:03:56.040
mainstream of tomorrow so within a couple years we should all be able to

00:03:53.319 --> 00:04:02.680
have enough memory bandwidth to choke a horse speaking of choking horses or nope

00:04:00.519 --> 00:04:06.920
not related to that at all Dollar Shave Club you can get razors and other

00:04:04.840 --> 00:04:11.480
bathroom supplies shipped directly to your door for only a few bucks a month

00:04:09.000 --> 00:04:16.759
they've got their razor handles and blade combos all the way up to the like

00:04:13.799 --> 00:04:20.759
six blade executive but with that said they don't go overboard and kind of go

00:04:19.040 --> 00:04:25.280
yeah well this one's got like a rear view mirror and a vibrating handle that

00:04:23.280 --> 00:04:28.880
you can use for all kinds of oh right they also have other products like their

00:04:26.880 --> 00:04:33.199
one wipe Charlie's peppermint scented butt wipes from their post shave

00:04:30.880 --> 00:04:37.759
moisturizer and their Dr Carver shave butter which goes on clear so you can

00:04:35.240 --> 00:04:41.639
actually see what you're doing I mean I guess it's pretty

00:04:39.720 --> 00:04:45.919
straightforward isn't it high quality razors and bathroom supplies directly to

00:04:43.600 --> 00:04:49.360
your door once a month for a few bucks a month visit
