1
00:00:00,080 --> 00:00:07,839
so i'm at the local computer store and i don't know what to do do i choose the

2
00:00:04,480 --> 00:00:11,040
ryzen x or the ryzen xt

3
00:00:07,839 --> 00:00:13,679
which one's more extreme i gotta say my

4
00:00:11,040 --> 00:00:17,039
patience for AMD's crazy naming schemes is starting to wear a little thin you

5
00:00:15,440 --> 00:00:23,119
know first they so funny copied Intel's chipset naming

6
00:00:19,600 --> 00:00:25,600
scheme for am4 then there's the 3000

7
00:00:23,119 --> 00:00:31,679
series ryzen mobile cpus that aren't third gen and now they're bringing xt

8
00:00:28,720 --> 00:00:37,680
their higher performance suffix for graphics cards to three new entries in

9
00:00:34,640 --> 00:00:40,559
their CPU lineup i just can't wait to

10
00:00:37,680 --> 00:00:44,399
have my search results for 5th gen ryzen processors full of navi Radeon graphics

11
00:00:43,600 --> 00:00:50,719
cards but rant over these new chips are in

12
00:00:47,840 --> 00:00:54,960
fact higher performance so let's see what they're all about shall we

13
00:00:53,760 --> 00:00:58,480
just like we're gonna see what our sponsor is all about glasswire is the

14
00:00:56,960 --> 00:01:02,320
tool that shows you which apps are slowing down your connection in real

15
00:01:00,559 --> 00:01:05,680
time it's used by security pros to monitor for malware block bandwidth

16
00:01:03,840 --> 00:01:10,439
wasters and detect suspicious activity get 25 off at the link below

17
00:01:17,119 --> 00:01:24,799
okay that bit about being in the store and being confused that's real the new

18
00:01:21,200 --> 00:01:27,200
xt chips are not a replacement for the x

19
00:01:24,799 --> 00:01:32,159
series processors AMD made that very clear to us in our briefing and in fact

20
00:01:29,439 --> 00:01:38,640
the x series is going to continue to sit on store shelves right alongside the xts

21
00:01:35,759 --> 00:01:42,400
for the same price now you could be forgiven for thinking that this is

22
00:01:40,400 --> 00:01:47,040
offset somewhat by the cost of the cooler that they don't have to include

23
00:01:44,720 --> 00:01:52,479
in the box for the xt's except that the ryzen 5 3600 xt does in

24
00:01:50,799 --> 00:01:56,880
fact come with a cooler in the box meaning that unless you're getting a

25
00:01:54,320 --> 00:02:00,799
really good deal there's even less reason than ever before to bother with

26
00:01:59,040 --> 00:02:06,000
the 3600x in fact AMD's reasoning for not

27
00:02:03,119 --> 00:02:11,280
including a cooler in the 3800 xt and 3900 xt that most consumers who buy

28
00:02:09,200 --> 00:02:16,319
ryzen 7 and ryzen 9 will probably buy an aftermarket cooler anyway

29
00:02:13,040 --> 00:02:18,879
makes sense and more or less obsoletes

30
00:02:16,319 --> 00:02:23,200
their x series equivalents as well so what are they doing

31
00:02:20,879 --> 00:02:28,080
when pressed about this AMD responded that they are giving consumers more

32
00:02:25,520 --> 00:02:32,239
choice by doing it this way and that while the suggested retail price is the

33
00:02:30,319 --> 00:02:36,560
same they're gonna leave the exact pricing up to the vendors

34
00:02:34,640 --> 00:02:41,360
that's a strange way of handling it but they hammered home this choice angle by

35
00:02:38,959 --> 00:02:45,360
proclaiming that the ryzen xt series doesn't even require a BIOS update which

36
00:02:43,280 --> 00:02:49,040
means that even oem motherboards like the kind you might get in a pre-built

37
00:02:47,120 --> 00:02:54,319
gaming system and that probably won't get regular BIOS updates can make use of

38
00:02:51,519 --> 00:02:58,959
these new cpus as well i mean fair enough i guess but this is still

39
00:02:56,480 --> 00:03:04,400
going to cause a ton of confusion on forum threads all over the internet so

40
00:03:02,560 --> 00:03:09,120
what are these then AMD says that the xt chips are the

41
00:03:07,200 --> 00:03:13,519
result of the maturation of the seven nanometer manufacturing process and the

42
00:03:11,680 --> 00:03:18,640
experience that they gained in producing third gen threadripper which is allowing

43
00:03:15,680 --> 00:03:25,280
them to not only improve boost clocks by 100 to 200 megahertz but also to improve

44
00:03:22,319 --> 00:03:29,840
residency at those boost clocks in a nutshell that means you'll see them

45
00:03:26,879 --> 00:03:34,560
boost higher and for longer given that AMD's precision boost 2 algorithm relies

46
00:03:32,000 --> 00:03:38,720
almost exclusively on thermal and power budget for boost in the first place

47
00:03:36,080 --> 00:03:42,720
though what exactly that means is something we're going to have to

48
00:03:39,920 --> 00:03:46,480
discover for ourselves in the real world to do that we filled our water bottle

49
00:03:44,799 --> 00:03:51,360
from lttstore.com and gathered no fewer than eight cpus

50
00:03:49,040 --> 00:03:55,680
with the lion's share of them being AMD to see how they tick

51
00:03:53,120 --> 00:04:00,959
without a BIOS update it definitely does boot up so let's see how AMD's claims

52
00:03:58,080 --> 00:04:07,439
hold up performance wise well we have a look at this graphics

53
00:04:03,200 --> 00:04:07,439
there's a new BIOS it's optimized again

54
00:04:11,200 --> 00:04:18,880
this doesn't make any sense yeah i know the ryzen 9 3900 xt is going slower than

55
00:04:16,479 --> 00:04:22,240
the 3900x that shouldn't be possible no it doesn't

56
00:04:20,880 --> 00:04:26,639
make any sense so we might have to call it the review

57
00:04:24,320 --> 00:04:29,600
well no wait hold on a second no no i think we're okay i mean AMD said we

58
00:04:28,160 --> 00:04:34,320
don't need a BIOS update in the first place and our older BIOS performs better with

59
00:04:32,800 --> 00:04:38,240
the xt even if the optimized one is worse no i

60
00:04:36,880 --> 00:04:43,680
think we're good we're going to go ahead with AMD's guidance we're going to use our original BIOS

61
00:04:41,440 --> 00:04:48,080
yeah so maybe down the line you'll see some performance gains with tuned BIOS's

62
00:04:46,160 --> 00:04:53,520
for these xt chips but for now we're going to evaluate as is especially

63
00:04:50,880 --> 00:04:57,919
because things are looking pretty good AMD has managed a measurable performance

64
00:04:55,919 --> 00:05:02,639
improvement in gaming far more than you might expect from a mere two percent

65
00:04:59,919 --> 00:05:10,320
clock improvement on the 3900 xt and 3600 xt and in fact the ryzen 9 3900 xt

66
00:05:07,199 --> 00:05:12,960
is now just shy of Intel's core i5 while

67
00:05:10,320 --> 00:05:18,080
having more course than either of team blue's ships which is darn impressive

68
00:05:15,280 --> 00:05:21,039
given that CPU is sometimes faster than its core i9 cousin when it comes to

69
00:05:20,080 --> 00:05:26,400
gaming overall depending on the game these new

70
00:05:23,440 --> 00:05:30,639
cpus manage anywhere from negligible to 10-ish percent improvements over their

71
00:05:28,720 --> 00:05:34,639
x-series counterparts the new hardware accelerated GPU

72
00:05:32,320 --> 00:05:38,320
scheduling feature in Windows 10 might help things even further in the near

73
00:05:36,960 --> 00:05:43,199
future and we're going to be diving into that soon so make sure you get subscribed so you don't miss it

74
00:05:41,600 --> 00:05:47,360
unsurprisingly these performance improvements also spill over into

75
00:05:44,960 --> 00:05:52,639
productivity where scores are measurably higher and consequently AMD ends up

76
00:05:50,240 --> 00:05:57,360
pulling farther ahead of Intel than before we're looking at just shy of a

77
00:05:55,199 --> 00:06:02,400
minute shaved off of the firefox compile test for both ryzen 9 and ryzen 5 and

78
00:06:00,880 --> 00:06:07,680
where the performance makes a real impact is in creative cloud where we see

79
00:06:04,800 --> 00:06:13,600
significant gains by reaching for the xt versus an x our ryzen 9 3900 xt pulled

80
00:06:11,360 --> 00:06:19,520
off a staggering 18 percent higher score in photoshop with its mere 100 megahertz

81
00:06:17,039 --> 00:06:24,400
boost clock improvement but then while the ryzen 5 pulled off better times in

82
00:06:21,840 --> 00:06:27,600
blender the ryzen 9 seems to be no better off than before so what's up with

83
00:06:26,720 --> 00:06:31,280
that maybe our thermal performance charts can

84
00:06:29,840 --> 00:06:37,199
shed some light in blender we found that the 3900 xt

85
00:06:34,560 --> 00:06:40,880
displays some of that stay boosted higher and more often promise in the

86
00:06:39,440 --> 00:06:47,759
early stages but it hovers between 4.1 gigahertz and

87
00:06:44,400 --> 00:06:50,560
the 3900x is 4 gigahertz and eventually

88
00:06:47,759 --> 00:06:54,639
tapers off to mostly four gigahertz by the latter half of the run then when we

89
00:06:52,720 --> 00:07:00,319
look at the power draw it's pretty baffling it's drawing far more power for

90
00:06:57,440 --> 00:07:08,639
the same or a slightly higher clock speed about 145 watts that's well above

91
00:07:04,560 --> 00:07:11,360
both its rated 105 watt TDP and the x's

92
00:07:08,639 --> 00:07:15,759
maximum of around 140 watts when it drops to 4 gigahertz that translates

93
00:07:13,440 --> 00:07:22,720
into significantly more heat output and with an h115i our 3900xt landed about 10

94
00:07:19,840 --> 00:07:27,120
degrees celsius hotter than the 3900x on the hottest eye the same thing doesn't

95
00:07:25,120 --> 00:07:30,479
happen though with the lower end xt chips which maintain their higher

96
00:07:28,639 --> 00:07:34,240
performance level over their x counterparts throughout the run and i

97
00:07:32,400 --> 00:07:36,720
gotta level with you guys here i don't really know how to interpret

98
00:07:35,840 --> 00:07:42,000
that it could be that power delivery is wonky

99
00:07:39,440 --> 00:07:46,000
on this older firmware for the high core count chip and it could be that it's

100
00:07:44,000 --> 00:07:50,479
something that's fixable in the future or it could be that higher thermal

101
00:07:48,080 --> 00:07:54,960
output means that precision boost 2 is simply dropping the turbo down sooner

102
00:07:52,720 --> 00:07:58,160
than those lower core count chips if it's power related i don't expect that

103
00:07:56,800 --> 00:08:04,560
this will be a problem with future firmware revisions as the 3950x with 16

104
00:08:01,680 --> 00:08:08,240
cores runs fine in this particular board but your mileage may vary a little in

105
00:08:06,720 --> 00:08:13,440
terms of thermals and sustained performance on launch day on the subject

106
00:08:10,800 --> 00:08:18,400
of launch day after AMD retired their original store mi solution based on an

107
00:08:16,160 --> 00:08:22,479
modis fuse drive which allowed you to accelerate a hard drive with a solid

108
00:08:20,240 --> 00:08:27,919
state cache they teased that a new solution would become available this

109
00:08:24,000 --> 00:08:30,240
year and it's launching now storm i 2.0

110
00:08:27,919 --> 00:08:34,959
AMD's internally developed read-only caching solution is apparently a whole

111
00:08:32,800 --> 00:08:39,680
lot easier to configure with support for any size of SSD and hard drive

112
00:08:37,760 --> 00:08:42,640
it's purely done in software which should mean it's compatible with

113
00:08:41,519 --> 00:08:49,600
anything but right now it only supports third gen

114
00:08:45,920 --> 00:08:52,240
ryzen chips on the x570 chipset as for

115
00:08:49,600 --> 00:08:56,080
why AMD says they're going to gradually roll out support for other chipsets and

116
00:08:54,240 --> 00:09:00,080
cpus so either they're artificially limiting the

117
00:08:58,000 --> 00:09:04,959
software feature to try to add value to x570 in the wake of the b550 launch

118
00:09:03,200 --> 00:09:09,040
or they want their most enthusiastic customers to participate in a beta

119
00:09:06,800 --> 00:09:13,279
program the good news is that given that it's a read-only caching solution any

120
00:09:11,279 --> 00:09:16,800
data that you store on it shouldn't be at risk so

121
00:09:14,959 --> 00:09:21,200
i don't know give it a try and let us know how it goes over on

122
00:09:18,360 --> 00:09:27,120
linustechtips.com in the forum overall this launch feels like a strange sort of

123
00:09:24,640 --> 00:09:32,160
weird message from AMD they're not replacing the x-series processors or

124
00:09:29,920 --> 00:09:37,519
formally discounting them so the bad news is that it's kind of confusing but

125
00:09:34,959 --> 00:09:42,000
the good news is that the only difficult part of our original choice

126
00:09:39,839 --> 00:09:46,240
is whether we want to take advantage of the marketing kickback programs or

127
00:09:43,839 --> 00:09:50,560
bundle deals that AMD seems to be hinting at

128
00:09:47,440 --> 00:09:53,440
or pony up msrp for a little bit more

129
00:09:50,560 --> 00:09:57,120
performance with an xt you know the cynic in me actually

130
00:09:54,959 --> 00:10:00,480
totally going off script here might say that they're keeping the old skus just

131
00:09:58,720 --> 00:10:04,959
so that they can have like more shelf space taken up by AMD

132
00:10:02,399 --> 00:10:10,160
products i've seen moves like that there was a really dark time in the GPU space

133
00:10:07,600 --> 00:10:14,560
when graphics card boxes started to get like this literally this big i remember

134
00:10:13,279 --> 00:10:18,640
uh chaintech chaintech used to have these

135
00:10:16,560 --> 00:10:22,959
gigantic graphics card boxes remember this is before the cards were even dual

136
00:10:20,880 --> 00:10:27,360
slot even like there was no reason for it whatsoever other than to make it take

137
00:10:24,880 --> 00:10:30,720
up as much space as possible so yeah it could be that as well speaking of things

138
00:10:29,279 --> 00:10:35,519
it could be it could be time for our sponsor if you're in charge of your company's

139
00:10:33,440 --> 00:10:43,200
server storage check out our sponsor keoxia their cm6 enterprise NVMe ssds

140
00:10:39,360 --> 00:10:44,959
are pci express 4.0 and NVMe 1.4

141
00:10:43,200 --> 00:10:49,839
compliant they come in two and a half inch form factors with up to 12.8

142
00:10:47,279 --> 00:10:56,560
terabytes of capacity and can sustain 1.4 million iops and over 6.9 gigabytes

143
00:10:53,760 --> 00:11:02,720
per second they're made with 96 layer 3d tlc memory and can sustain and recover

144
00:10:59,600 --> 00:11:04,640
from a simultaneous to die failure

145
00:11:02,720 --> 00:11:08,640
that sounds pretty good so check them out at the link in the video description

146
00:11:07,040 --> 00:11:12,480
so thanks for watching guys if you enjoyed this video go check out our

recent video on what it takes to cool Intel's core i9 10 900k

148
00:11:15,519 --> 00:11:21,040
you might have noticed we didn't criticize AMD too hard for the extra

149
00:11:19,040 --> 00:11:24,800
power draw or the extra 10 degrees because they were already in pretty good

150
00:11:22,240 --> 00:11:29,640
shape as for Intel that thing can draw over

151
00:11:25,560 --> 00:11:29,640
250 watts

152
00:11:30,240 --> 00:11:33,240
