00:00:00.060 --> 00:00:07.140
there's nothing like unboxing a shiny new graphics card but they're just so

00:00:04.680 --> 00:00:11.760
bulky why is it that we can't just buy the GPU by itself and Slot it directly

00:00:09.720 --> 00:00:16.199
onto our motherboard like we do for CPUs it turns out there are a lot of reasons

00:00:13.980 --> 00:00:22.380
that it's just not that simple and a big one is power you see a mid to high end

00:00:19.560 --> 00:00:25.980
discrete GPU draws lots of power to the point where it's typically the single

00:00:24.060 --> 00:00:30.119
most power hungry component in your system and you can see this if you look

00:00:28.380 --> 00:00:34.559
at a graphics card with the cooler removed many of those little components

00:00:32.700 --> 00:00:38.760
that you see all over the board are dedicated to power delivery and voltage

00:00:36.780 --> 00:00:43.140
regulation which is part of the reason that graphics cards tend to be quite

00:00:40.920 --> 00:00:47.160
large putting these components onto the motherboard would not only make it

00:00:44.820 --> 00:00:51.660
larger but also significantly more expensive but that's far from the only

00:00:49.200 --> 00:00:56.280
logistical concern another big one is memory you see although integrated

00:00:54.120 --> 00:01:02.160
Graphics can share your system's standard DDR RAM and some lower end

00:00:59.280 --> 00:01:07.080
discrete gpus actually use dedicated but still run-of-the-mill DDR mid and higher

00:01:05.159 --> 00:01:12.840
range options use special video RAM called GDDR with the G being for

00:01:09.720 --> 00:01:14.580
graphics GDDR is higher bandwidth

00:01:12.840 --> 00:01:19.200
because it's designed to handle large chunks of data such as the visual assets

00:01:17.280 --> 00:01:24.840
and textures that your GPU is continually asking for by contrast

00:01:21.659 --> 00:01:26.700
normal DDR is better at handling smaller

00:01:24.840 --> 00:01:31.680
pieces of data so it doesn't have as much bandwidth but its latency is lower

00:01:29.159 --> 00:01:36.360
this means that if you were to put a relatively powerful GPU directly onto a

00:01:34.200 --> 00:01:41.700
motherboard you would also need to build in dedicated GDDR memory which would you

00:01:40.020 --> 00:01:46.079
guessed it make the motherboard even bigger and even more expensive now

00:01:44.220 --> 00:01:50.460
hypothetically you could design this video memory or vram to be slotted in

00:01:48.659 --> 00:01:54.720
rather than slaughtered directly to the graphics card but this actually has the

00:01:52.920 --> 00:01:58.979
possibility of increasing the rate of data errors which is a big part of the

00:01:57.000 --> 00:02:03.479
reason that all modern graphics cards use soldered on vram even if you could

00:02:01.799 --> 00:02:06.840
solve the memory and power issues though there's another big roadblock that will

00:02:39.300 --> 00:02:45.900
annual little subscription another huge hurdle to having a GPU socket on your

00:02:42.959 --> 00:02:50.940
motherboard is the socket itself you know how AMD and Intel CPUs use

00:02:48.060 --> 00:02:55.680
completely different socket designs and even within AMD or within Intel you end

00:02:54.180 --> 00:02:59.340
up having to upgrade your motherboard ever so often when they decide to change

00:02:57.959 --> 00:03:04.560
the pin layout well you would have the same problem

00:03:01.080 --> 00:03:06.959
with a GPU socket but arguably worse as

00:03:04.560 --> 00:03:11.700
there are now three discrete GPU manufacturers with Intel entering The

00:03:08.580 --> 00:03:14.340
Fray and GPU architectures tend to be

00:03:11.700 --> 00:03:17.640
updated more frequently and more dramatically than on the CPU side

00:03:16.080 --> 00:03:22.980
meaning that motherboards would go out of date much more quickly not to mention

00:03:20.099 --> 00:03:28.140
that you'd be locked into one CPU vendor and one GPU vendor every time you bought

00:03:26.099 --> 00:03:33.239
a new one none of this even mentions that all those different gpus would

00:03:30.540 --> 00:03:38.040
necessitate different amounts of power delivery and vram so you'd either have

00:03:36.060 --> 00:03:41.879
the problem where you'd need a stupidly huge lineup of different motherboards

00:03:39.900 --> 00:03:46.500
from every manufacturer to accommodate all these different variations or you'd

00:03:44.519 --> 00:03:50.940
have to over engineer every motherboard with enough power and memory to support

00:03:48.180 --> 00:03:54.120
the entire GPU product stack which might put you in a position where you'd have

00:03:52.200 --> 00:03:57.959
to consider selling organs for a motherboard finally there's the reality

00:03:56.340 --> 00:04:02.159
that although graphics cards are hot Commodities with Gamers there are many

00:04:00.000 --> 00:04:05.760
more people out there that don't need a powerful GPU meaning that motherboards

00:04:04.260 --> 00:04:09.540
with GPU sockets on them would be relegated to a very niche market due to

00:04:08.099 --> 00:04:13.680
how expensive they'd be giving manufacturers even less of an incentive

00:04:11.700 --> 00:04:17.100
to make them so for the time being if you want a GPU on your motherboard it's

00:04:15.659 --> 00:04:21.660
probably only going to happen in a laptop or other specialized device on

00:04:19.680 --> 00:04:25.139
the desktop it's just so much cheaper and easier for them to continue doing

00:04:23.400 --> 00:04:30.660
what they've been doing slotting them into universally compatible inexpensive

00:04:27.600 --> 00:04:32.520
PCI Express slots and besides do you

00:04:30.660 --> 00:04:36.720
really want to strap another cooler to your motherboard what you really want to
