1
00:00:00,380 --> 00:00:06,080
AMD is back and NVIDIA is about to pay

2
00:00:04,080 --> 00:00:11,880
for their outrageous pricing practices the rdna3 announcement just concluded

3
00:00:09,480 --> 00:00:15,960
and while AMD gave us very little in the way of meaningful

4
00:00:13,679 --> 00:00:21,359
performance data I'm really optimistic anyway and here's why immediately after

5
00:00:19,020 --> 00:00:26,760
the stream ended our Labs team sprang into action building up test benches as

6
00:00:24,300 --> 00:00:32,579
close as possible to the ones that AMD used in their performance preview that

7
00:00:28,980 --> 00:00:35,160
allowed us to expand on AMD's rather

8
00:00:32,579 --> 00:00:41,100
vague slides that didn't include a single NVIDIA GPU and extrapolate some

9
00:00:38,100 --> 00:00:43,980
actually useful comparative performance

10
00:00:41,100 --> 00:00:48,360
data now the bad news is that NVIDIA might still be the performance King but

11
00:00:46,200 --> 00:00:54,660
the good news is that I can confidently say that AMD's new Radeon RX 7900 XTX

12
00:00:52,079 --> 00:01:01,980
should come within spitting distance of NVIDIA's RTX 4090 for 600 dollars less

13
00:01:00,360 --> 00:01:08,100
the only thing with better performance per dollar is this segue to our sponsor

18
00:01:28,280 --> 00:01:33,540
in AMD's together we advance underscore

19
00:01:31,560 --> 00:01:40,860
gaming live event they announced the two Flagship tier gpus that will lead their

20
00:01:35,939 --> 00:01:45,600
rdna 3 family the Radeon RX 7900 XT and

21
00:01:40,860 --> 00:01:48,659
7900 XTX with 20 and 24 gigabytes of

22
00:01:45,600 --> 00:01:51,000
gddr6 respectively which was my first

23
00:01:48,659 --> 00:01:55,520
surprise I mean why would they cheap out on the memory when they need to compete

24
00:01:52,979 --> 00:02:00,600
with NVIDIA cards that are using faster gddr6x two reasons one to save power

25
00:01:59,520 --> 00:02:04,500
which fair enough given the reputation their

26
00:02:02,520 --> 00:02:09,899
competition is built for unreasonable power consumption in thermals and two

27
00:02:07,380 --> 00:02:15,239
they just don't seem to need it the most useful slide that AMD provided was this

28
00:02:12,120 --> 00:02:18,660
one where we see the 7900 XTX performing

29
00:02:15,239 --> 00:02:22,980
between one and a half to 1.7 times the

30
00:02:18,660 --> 00:02:25,800
outgoing Flagship 6950xt at 4K now AMD

31
00:02:22,980 --> 00:02:29,940
was frustratingly vague about the exact settings that they used to achieve these

32
00:02:27,720 --> 00:02:35,640
results even when we probed them after the event but we managed to extract just

33
00:02:33,300 --> 00:02:41,220
enough information to create our own set of performance graphs by extrapolating

34
00:02:37,800 --> 00:02:45,060
from our own reference 6950xt

35
00:02:41,220 --> 00:02:48,360
let's start with cyberpunk 2077 AMD's

36
00:02:45,060 --> 00:02:52,080
previous best managed 46 FPS

37
00:02:48,360 --> 00:02:54,900
not great but multiply that by 1.7 and

38
00:02:52,080 --> 00:03:00,540
we've got a spicy 78 frames per second that's just a single frame per second

39
00:02:57,480 --> 00:03:02,580
behind the RTX 4090 what a generational

40
00:03:00,540 --> 00:03:09,420
Improvement in Call Of Duty Modern Warfare 2 our RX 6950xt managed a

41
00:03:06,480 --> 00:03:15,420
respectable 90 FPS when we multiply that by AMD's 1.5 times assuming of course

42
00:03:12,720 --> 00:03:21,959
they're not just outright lying we can expect the 7900 XTX to lag NVIDIA's

43
00:03:18,239 --> 00:03:25,500
Flagship by only six percent hot dang

44
00:03:21,959 --> 00:03:27,840
finally in Watchdogs Legion the 7900 XTX

45
00:03:25,500 --> 00:03:33,500
takes its largest L compared to the RTX 4090 but that still only has it lagging

46
00:03:31,319 --> 00:03:39,060
behind by about 10 not too shabby AMD

47
00:03:36,480 --> 00:03:44,760
of course performance is meaningless if it'll cost you two fingers and your

48
00:03:41,099 --> 00:03:47,940
right butt cheek NVIDIA and I have more

49
00:03:44,760 --> 00:03:50,519
good news the 7900 XTX is a thousand

50
00:03:47,940 --> 00:03:54,959
dollars while the 7900 XT comes in a hundred less at 900 which

51
00:03:53,159 --> 00:04:00,840
I mean I never thought I'd be happy about even a top-tier GPU being only a

52
00:03:58,620 --> 00:04:05,819
thousand dollars but I guess that really shows just how out to lunch NVIDIA has

53
00:04:03,900 --> 00:04:10,980
been with the pricing of the RTX 4000 series but wait a second didn't NVIDIA's

54
00:04:08,640 --> 00:04:16,440
CEO Jensen go out on stage and basically say the pricing is so high because the

55
00:04:13,620 --> 00:04:21,359
factors outside is control Moore's Law is dead he said

56
00:04:18,299 --> 00:04:24,360
well how did AMD pull it off then well

57
00:04:21,359 --> 00:04:26,540
first of all by not using the latest and

58
00:04:24,360 --> 00:04:33,120
greatest manufacturing process rdna 3 gpus at least the ones we've seen

59
00:04:29,699 --> 00:04:37,139
so far are made using a combination of

60
00:04:33,120 --> 00:04:40,080
tsmc's five nanometer and six nanometer

61
00:04:37,139 --> 00:04:46,800
processes making this both the very first chiplet design GPU and way cheaper

62
00:04:44,400 --> 00:04:51,960
to manufacture than the four nanometer monolithic dies that NVIDIA uses for RTX

63
00:04:49,680 --> 00:04:55,320
4000 but you'd think there'd be a downside to that right like don't hold

64
00:04:53,639 --> 00:04:59,220
their manufacturing nodes have worse power consumption

65
00:04:56,699 --> 00:05:06,900
believe it or not the total board power of the 7900 XT and XTX is just 300 and

66
00:05:03,860 --> 00:05:08,880
355 Watts respectively and it's

67
00:05:06,900 --> 00:05:14,280
delivered by two good old-fashioned eight-pin PCIe power connectors I never

68
00:05:11,639 --> 00:05:19,139
thought I'd be adding not a fire hazard as a selling point for a GPU but here we

69
00:05:17,220 --> 00:05:24,720
are this also means that if you're upgrading from something like a GTX 1080

70
00:05:21,360 --> 00:05:26,340
TI or an RTX 2080 you probably don't

71
00:05:24,720 --> 00:05:32,520
need to upgrade your system power supply and you also probably don't need to

72
00:05:29,220 --> 00:05:35,160
upgrade your case the reference 7900 XTX

73
00:05:32,520 --> 00:05:39,479
is a much more reasonable 287 millimeters wide and two and a half

74
00:05:37,259 --> 00:05:45,000
slots tall compared to the 304 millimeters and three and a half Slots

75
00:05:41,820 --> 00:05:46,919
of the RTX 4090 again I never thought a

76
00:05:45,000 --> 00:05:51,120
GPU physically fitting in your computer would be a major selling point

77
00:05:48,960 --> 00:05:56,400
but here we are how did they do this then well AMD also

78
00:05:54,419 --> 00:06:01,380
packed in some really cool power management Innovations for starters they

79
00:05:59,400 --> 00:06:07,199
decoupled the clock speed of the shaders which now run at up to 2.3 gigahertz and

80
00:06:04,440 --> 00:06:11,400
the front end which runs at 2.5 we've actually seen this before in Mobile

81
00:06:08,580 --> 00:06:15,060
products but never in a desktop GPU and the main benefit of this approach is

82
00:06:13,199 --> 00:06:19,979
that it allows them to prioritize the speed of one over the other depending on

83
00:06:17,699 --> 00:06:23,940
the workload for instance if the gain you're running doesn't hit the shaders

84
00:06:21,539 --> 00:06:29,639
super hard maybe those are fine just sipping power at 1.8 gigahertz while the

85
00:06:27,060 --> 00:06:35,340
front end runs at full speed AMD says this can reduce total power consumption

86
00:06:31,500 --> 00:06:37,259
by 25 percent which might not be

87
00:06:35,340 --> 00:06:41,639
something you care about if you have a beefy power supply and a well-cooled

88
00:06:38,940 --> 00:06:45,479
case already though fear not AMD says there will be aib partner cards with

89
00:06:43,800 --> 00:06:50,880
more Cooling and higher power consumption to enable even higher clock

90
00:06:47,580 --> 00:06:52,979
speeds or AMD says anyway so far we've

91
00:06:50,880 --> 00:06:56,220
only only found this ASUS tough model with three eight pin connectors which

92
00:06:54,840 --> 00:07:01,020
might indicate higher power consumption but nothing to say of the clock speeds

93
00:06:59,039 --> 00:07:06,300
now possibly the dumbest problem with the RTX 4090 aside from the burning up

94
00:07:04,259 --> 00:07:11,340
12 pin power adapters is that it only supports DisplayPort 1.4 which given how

95
00:07:09,660 --> 00:07:15,660
freaking fast it is could actually become a problem in the very near future

96
00:07:13,319 --> 00:07:19,979
as new displays become available AMD on the other hand managed to avoid

97
00:07:18,060 --> 00:07:25,020
this embarrassing situation by including DisplayPort 2.1 which can support

98
00:07:22,680 --> 00:07:34,680
ridiculous resolutions and frame rate combinations like 4K 480 Hertz or 8K 165

99
00:07:31,380 --> 00:07:36,960
Hertz now obviously whether you go team

100
00:07:34,680 --> 00:07:41,699
green or team red your GPU won't be able to keep up with that today but with the

101
00:07:39,840 --> 00:07:47,160
way that upscaling and frame generation technology is progressing DP 2.1 is some

102
00:07:44,940 --> 00:07:51,599
massive future proofing that could make the RTX 4090 unable to take full

103
00:07:49,979 --> 00:07:56,699
advantage of monitors that could be releasing as early as next year

104
00:07:53,940 --> 00:08:03,360
AMD has also included a new media engine that has 8K 60 av1 and code and decode

105
00:08:01,139 --> 00:08:06,900
support this is a huge Boon for streamers who are looking to get the

106
00:08:04,740 --> 00:08:11,699
best image quality going forward and they announced smart access video which

107
00:08:09,360 --> 00:08:18,240
can share the load of encode and decode operations between AMD gpus and CPUs

108
00:08:15,000 --> 00:08:20,639
apparently giving a 30 uplift in 4k

109
00:08:18,240 --> 00:08:25,379
multi-stream transcoding though we'll have to see how well this actually works

110
00:08:22,440 --> 00:08:29,759
when it lands an OBS in December I'm a little skeptical but In fairness to AMD

111
00:08:27,960 --> 00:08:34,200
the recent software upgrades that they made to their media engine for Radeon

112
00:08:31,319 --> 00:08:37,500
6000 did bring about image quality improvements to get them closer to

113
00:08:35,940 --> 00:08:42,479
NVIDIA zenbank than I would have thought possible so with this new media engine

114
00:08:39,779 --> 00:08:46,920
AMD might finally be a sensible choice for people who want to stream or record

115
00:08:44,520 --> 00:08:51,420
their gameplay another sensible choice is signing up for Floatplane.com for

116
00:08:49,380 --> 00:08:55,260
amazing behind the scenes and Extras like the shooting of our starforge

117
00:08:53,279 --> 00:08:59,760
systems review intro to be clear not everything that AMD

118
00:08:57,240 --> 00:09:05,339
announced today was mind-blowing in AMD's own slides they show a 1.5 to 1.6

119
00:09:03,480 --> 00:09:10,320
times increase in Ray tracing performance which

120
00:09:06,720 --> 00:09:14,519
will take you from literal slideshow to

121
00:09:10,320 --> 00:09:17,760
cinematic FPS at best and the RTX 4090

122
00:09:14,519 --> 00:09:19,800
walked all over AMD's best at nearly

123
00:09:17,760 --> 00:09:25,740
double the frame rate based on our cyberpunk test and these projected

124
00:09:22,320 --> 00:09:27,980
numbers also AMD built new AI

125
00:09:25,740 --> 00:09:34,019
accelerators that should allow for up to 2.7 times more AI throughput per compute

126
00:09:31,380 --> 00:09:38,519
unit but the way it's implemented makes this increase only matter for games at

127
00:09:37,019 --> 00:09:43,860
the moment it's not going to help you with general purpose Ai and actually

128
00:09:41,040 --> 00:09:49,680
come to think of it there was almost no mention whatsoever of non-gaming tasks

129
00:09:46,980 --> 00:09:54,360
and this this is a long time thorn in Radeon users sides some applications

130
00:09:52,260 --> 00:09:59,760
like blender or SolidWorks visualize only support NVIDIA Cuda making NVIDIA

131
00:09:57,300 --> 00:10:04,320
cards absolutely embarrass their AMD counterparts and it doesn't look like

132
00:10:02,100 --> 00:10:10,320
this is going to change anytime soon AMD also promised that their new fsr3

133
00:10:07,800 --> 00:10:15,420
upscaling would be up to a two times increase over fsr2 but it looks like at

134
00:10:14,220 --> 00:10:21,180
least one of the ways they're going to achieve this is with technology similar

135
00:10:17,880 --> 00:10:23,160
to NVIDIA's dlss 3 by generating new

136
00:10:21,180 --> 00:10:28,140
frames and well let's just say we're currently

137
00:10:25,860 --> 00:10:32,220
working on a video about dlss3 and its frame generation and

138
00:10:29,640 --> 00:10:37,920
it's a first gen product overall though it looks like the RX 7900 XT and XTX are

139
00:10:35,760 --> 00:10:41,160
going to be hacking fast gpus for the money and this might end up being the

140
00:10:39,779 --> 00:10:46,800
first generation of what feels like forever where AMD is positioned to grab

141
00:10:44,220 --> 00:10:51,660
a good chunk of market share from our green overlords which will hopefully

142
00:10:49,380 --> 00:10:56,940
push NVIDIA to compete harder on pricing and meanwhile give AMD's GPU division

143
00:10:54,600 --> 00:11:01,260
the cash that it needs to ramp up r d spending and come back even stronger

144
00:10:59,040 --> 00:11:05,220
next time I can't wait to give you guys the full review when these cards launch

145
00:11:02,820 --> 00:11:09,899

156
00:11:47,880 --> 00:11:52,880
not that bad even if the price is still obscene
