1
00:00:00,160 --> 00:00:06,240
do you remember a time not so long ago when one of the hallmarks of a super

2
00:00:04,080 --> 00:00:10,400
high-end gaming rig was having multiple graphics cards and why not you could get

3
00:00:08,240 --> 00:00:15,599
high settings high resolutions and high frame rates to a point unattainable by

4
00:00:12,800 --> 00:00:19,600
mere mortals but here we are in 2019 and it almost seems like things have taken a

5
00:00:17,359 --> 00:00:25,519
step backwards in that it's becoming less and less common to see sli and

6
00:00:22,240 --> 00:00:27,439
crossfire setups so why is this the case

7
00:00:25,519 --> 00:00:31,519
when gamers are still interested in getting the best experience possible so

8
00:00:29,760 --> 00:00:36,480
as we partially explained in a previous video part of the lack of appeal comes

9
00:00:34,079 --> 00:00:42,239
from technical issues inherent to the platform you see in a dual GPU setup

10
00:00:39,280 --> 00:00:45,680
each GPU renders every other frame in a process called

11
00:00:43,440 --> 00:00:50,000
alternate frame rendering which makes intuitive sense but not only do the

12
00:00:48,000 --> 00:00:54,879
cards have a hard time syncing up with each other producing a visual glitch

13
00:00:51,680 --> 00:00:57,199
called micro stutter afr also doesn't

14
00:00:54,879 --> 00:01:01,920
always play nicely with more modern anti-aliasing methods that rely on data

15
00:00:59,600 --> 00:01:05,760
from the previous frame to guess what the next frame should look like and

16
00:01:04,080 --> 00:01:10,000
newer technologies haven't completely solved the problems that cards in a

17
00:01:07,439 --> 00:01:14,240
multi-GPU setup have communicating with each other on the NVIDIA side although

18
00:01:12,159 --> 00:01:16,880
there's a new bus called nvlink which has greater bandwidth than traditional

19
00:01:15,920 --> 00:01:21,840
sli not all of its features such as resource

20
00:01:19,200 --> 00:01:25,920
pooling work with consumer grades cards it was designed for professional GPU

21
00:01:23,520 --> 00:01:30,799
compute applications in mind not gamers newer apis such as vulkan and directx 12

22
00:01:28,720 --> 00:01:35,119
also haven't made the situation any easier for the average consumer you see

23
00:01:32,880 --> 00:01:40,320
in the past sli and crossfire took a more active role in handling the task of

24
00:01:38,000 --> 00:01:44,960
splitting game workloads across cards however newer apis give more control to

25
00:01:42,880 --> 00:01:49,119
the game developer so that they can code for multi-GPU in a way that they see fit

26
00:01:47,680 --> 00:01:53,520
and although this sounds like it could lead to games using multiple cards more

27
00:01:51,200 --> 00:01:56,799
efficiently it turns out that developers simply

28
00:01:54,399 --> 00:02:00,799
don't want to take on the burdensome extra workload of coding specifically

29
00:01:58,880 --> 00:02:06,640
for a setup that not many people are using so lots of modern games simply are

30
00:02:03,680 --> 00:02:10,800
not well optimized for multi-GPU and as if all these issues weren't enough to

31
00:02:08,319 --> 00:02:15,599
keep gamers away from sli and crossfire the fact that cards are now more

32
00:02:12,879 --> 00:02:21,440
powerful makes multi-GPU even less appealing although many of us marvel at

33
00:02:18,160 --> 00:02:23,599
4k ultra wide and multi-monitor gaming

34
00:02:21,440 --> 00:02:29,520
battle stations the fact is that most gamers are still playing at 1080p and a

35
00:02:26,800 --> 00:02:33,680
solid single current gen card can run most games at high or even maximum

36
00:02:31,680 --> 00:02:37,360
settings at smooth frame rates which wasn't necessarily the case just a few

37
00:02:35,599 --> 00:02:41,519
years ago this means that a problem that multi-GPU has already had buying two

38
00:02:39,840 --> 00:02:45,519
cards and then having a single card from the next generation come along and

39
00:02:43,200 --> 00:02:49,840
provide more similar performance is even more pronounced nowadays and with many

40
00:02:47,519 --> 00:02:53,440
gamers simply not caring about niche setups with diminishing returns or

41
00:02:51,760 --> 00:02:57,040
having the money to even afford them if they do care

42
00:02:55,280 --> 00:03:02,000
there hasn't been a compelling case for more multi-GPU adoption and of course

43
00:03:00,080 --> 00:03:06,000
being surprised that sli and crossfire aren't more popular presupposes that

44
00:03:04,159 --> 00:03:08,959
graphically demanding games are dominating the market

45
00:03:07,519 --> 00:03:13,280
while there still are plenty of beautiful aaa titles that end up

46
00:03:11,040 --> 00:03:17,840
becoming best sellers there's been a resurgent interest in 2d and retro style

47
00:03:15,840 --> 00:03:22,959
games that don't require nearly as much computing muscle to run

48
00:03:19,680 --> 00:03:25,920
you simply do not need a 2 000 multi GPU

49
00:03:22,959 --> 00:03:29,920
rig to run cuphead or sonic mania and even many popular current 3d titles like

50
00:03:28,159 --> 00:03:34,239
fortnite don't require expensive hardware as they're designed for broad

51
00:03:31,920 --> 00:03:37,760
appeal rather than the best looking graphics possible then again if you're

52
00:03:36,080 --> 00:03:40,799
the type of person who drives a lifted truck just so you can have the biggest

53
00:03:39,200 --> 00:03:44,840
vehicle on the block shelling out the extra money for a second graphics card

54
00:03:42,480 --> 00:03:49,360
