1
00:00:00,160 --> 00:00:05,200
Intel's been the industry's favorite punching bag for the last few years

2
00:00:03,679 --> 00:00:09,760
we've certainly taken our fair share of cheap shots but that changes today

3
00:00:07,600 --> 00:00:14,240
because chips like this with two different kinds of cores in them or more

4
00:00:12,240 --> 00:00:18,720
are probably the direction the entire industry is going to go that's right

5
00:00:16,400 --> 00:00:24,080
Intel jumped on the bandwagon with ARM and apple for their best generational

6
00:00:21,119 --> 00:00:28,000
upgrade in at least a decade but let's back up a sec

7
00:00:25,760 --> 00:00:32,399
this isn't going to be another furnace like past generations is it and if

8
00:00:30,400 --> 00:00:37,360
they're cheaping out juicing up their spec sheets with these

9
00:00:34,480 --> 00:00:42,800
low performance efficiency cores how could they possibly compare to AMD

10
00:00:40,079 --> 00:00:46,559
who ships only high performance cores our sponsor Corsair doesn't know thanks

11
00:00:45,120 --> 00:00:51,280
Corsair for sponsoring this video Corsair's xenion gaming monitor is an

12
00:00:48,640 --> 00:00:55,840
ultra slim 32 inch qhd gaming monitor with up to 165hz refresh rate one

millisecond response times and more learn more at the link below

14
00:01:06,720 --> 00:01:12,880
12th gen core codename alder lake is a paradigm shift for desktop processors

15
00:01:11,280 --> 00:01:16,560
but it's also one that we've had in mobile for quite some time and the tl dr

16
00:01:15,520 --> 00:01:21,759
is this instead of stuffing as many full power

17
00:01:19,040 --> 00:01:26,240
cores into the CPU as possible then turboing them down when they're all

18
00:01:23,600 --> 00:01:32,400
active the cores are now split up between performance and efficiency cores

19
00:01:29,280 --> 00:01:35,439
called p and e-course respectively the

20
00:01:32,400 --> 00:01:37,280
launch lineup ranges from 10 to 16 total

21
00:01:35,439 --> 00:01:41,200
cores with the main differences between them being of course clock speed and

22
00:01:39,439 --> 00:01:45,280
that the performance cores are capable of running two threads at once via hyper

23
00:01:43,360 --> 00:01:49,280
threading there's more to the platform than that but the first question you

24
00:01:47,119 --> 00:01:54,799
guys have is how does all of this impact performance great question but we need

25
00:01:51,680 --> 00:01:56,720
to talk about Windows 11 first it's kind

26
00:01:54,799 --> 00:02:00,960
of a prerequisite for testing elder lake's radical new design because the

27
00:01:58,320 --> 00:02:05,119
thing is Windows 10 just doesn't have a scheduler that's capable of taking full

28
00:02:02,880 --> 00:02:10,160
advantage of this new architecture this is a huge problem because up until now

29
00:02:07,520 --> 00:02:13,680
Windows 11's new scheduler hasn't been kind to AMD

30
00:02:11,760 --> 00:02:17,760
thankfully the fixes for performance issues on ryzen came out just as we were

31
00:02:15,840 --> 00:02:21,520
starting our benchmarks so our numbers should be fair to both sides in spite of

32
00:02:20,080 --> 00:02:25,360
the fact that we're benchmarking on Windows 11. we do need to address

33
00:02:23,280 --> 00:02:31,360
another big variable here though alder lake supports both ddr4 and ddr5 which

34
00:02:29,200 --> 00:02:35,120
each have their own trade-offs we chose ddr5 for our launch review meaning that

35
00:02:33,280 --> 00:02:39,599
our numbers are going to represent a best-case scenario for performance

36
00:02:37,519 --> 00:02:45,280
but maybe won't represent a best-case scenario for value due to ddr5's higher

37
00:02:42,319 --> 00:02:50,239
cost f1 2021 starts things off with a bang for Intel with the core i9 12900k

38
00:02:47,760 --> 00:02:55,599
coming in at 5 to 10 faster than its ryzen nine competitors and the core i5

39
00:02:53,040 --> 00:03:00,800
just a hair's breadth away can Intel keep it up with forza oh yeah they can

40
00:02:58,720 --> 00:03:04,000
that is anywhere from eight to eleven percent faster depending on the

41
00:03:02,080 --> 00:03:08,800
parameter you're looking at and whatever advantage Intel has here probably clock

42
00:03:06,159 --> 00:03:15,040
speed it's paying off in far cry 6 too with an even bigger lead it is up to 25

43
00:03:12,800 --> 00:03:20,000
faster than the competition and never dipped below 100 frames per second and

44
00:03:18,480 --> 00:03:25,519
if you've been paying close attention to the graphs the core i5 has never been

45
00:03:22,959 --> 00:03:30,959
far behind making life really difficult for our previous value gaming darling

46
00:03:28,319 --> 00:03:34,959
the ryzen 5 5600x moving on to microsoft flight simulator

47
00:03:33,200 --> 00:03:41,200
well this is a bit of a mess isn't it the ryzen 9 5900x beats out the core i9

48
00:03:38,799 --> 00:03:46,640
with the higher turboing not to mention higher core count 5950x

49
00:03:43,760 --> 00:03:50,480
falling behind even the ryzen 5. given how lightly threaded flight simulator

50
00:03:48,400 --> 00:03:53,920
has been so far this might just be an example of the new Windows 11 scheduler

51
00:03:52,560 --> 00:03:58,560
running up against something that it didn't expect in spite of the fixes in

52
00:03:56,319 --> 00:04:03,439
fact we almost threw this test out due to the weirdness but we felt like

53
00:04:00,879 --> 00:04:07,840
whatever's going on this is one scenario where Intel's new silicon isn't as

54
00:04:05,360 --> 00:04:11,840
dominant as they'd like it to be and is possibly also an area of investigation

55
00:04:09,760 --> 00:04:16,239
for AMD and microsoft then you've got situations like cs csgo where Intel

56
00:04:13,920 --> 00:04:20,239
treats us to even more ludicrous frame rates in the dust 2 benchmark and

57
00:04:18,000 --> 00:04:26,160
civilization 6 where our turn times are a good 7 to 10 percent shorter than on

58
00:04:23,040 --> 00:04:28,400
team red which could make that one more

59
00:04:26,160 --> 00:04:32,400
turn before bed go by a little quicker overall our testing has firmly

60
00:04:30,320 --> 00:04:36,960
demonstrated that Intel has reclaimed its crown for gaming performance with

61
00:04:34,080 --> 00:04:41,680
the core i9 enjoying a solid 7 overall lead over ryzen 9 and the core i5

62
00:04:39,520 --> 00:04:46,080
pulling ahead even further compared to the ryzen 5. man

63
00:04:43,840 --> 00:04:51,040
this kind of competition is what i signed up for when ryzen first launched

64
00:04:48,479 --> 00:04:55,280
now Intel famously thinks that cinebench is not really a real world test but

65
00:04:53,759 --> 00:04:59,840
they've got cost to celebrate these numbers for a change cinebench tends to

66
00:04:57,680 --> 00:05:04,800
scale linearly with core count so the fact that a CPU that has only eight

67
00:05:02,320 --> 00:05:10,720
proper performance cores could dethrone the ryzen 9 is an achievement perhaps

68
00:05:07,840 --> 00:05:15,199
fueled in part by its ddr5 memory it also demonstrates that those

69
00:05:12,320 --> 00:05:18,479
efficiency cores ain't your grandma's efficiency course they clearly pack some

70
00:05:17,600 --> 00:05:25,600
punch while the firefox compile did take a little longer on the core i9 versus the

71
00:05:22,240 --> 00:05:28,320
5950x Intel still won out in the bursty

72
00:05:25,600 --> 00:05:31,919
bmw blender render although they lost ground on the higher endurance

73
00:05:29,759 --> 00:05:36,240
gooseberry test showing that for really serious multi-core work AMD is still the

74
00:05:34,639 --> 00:05:43,039
more compelling option and aside though here that core i5 be

75
00:05:38,800 --> 00:05:44,560
looking more like a 5800x than a 5600x

76
00:05:43,039 --> 00:05:48,400
keep that in mind for when we discuss pricing later

77
00:05:46,080 --> 00:05:53,360
now strangely corona benchmark seems to come back in favor of AMD's additional

78
00:05:50,720 --> 00:05:58,160
course which shows that 3d rendering may be becoming more than simply a raw how

79
00:05:55,919 --> 00:06:01,759
many cores do you have game puget bench for its part benefits from

80
00:06:00,000 --> 00:06:06,319
what Intel's got on tap with a healthy lead especially in photoshop over AMD

81
00:06:04,240 --> 00:06:11,840
although Intel falls short in spec workstation where the only consistent

82
00:06:08,319 --> 00:06:14,080
wins are against the 5900x check out the

83
00:06:11,840 --> 00:06:18,160
financial services and energy tests guys where the 5950x still lives in a league

84
00:06:16,800 --> 00:06:23,120
of its own if you look at all the productivity benchmarks together though you'll see that the core i9 averages

85
00:06:21,360 --> 00:06:29,759
about three percent lower than the more expensive 5950x and 10 higher than the

86
00:06:26,880 --> 00:06:33,280
less expensive 5900x which puts it in kind of weird

87
00:06:30,960 --> 00:06:39,360
might be worth it might not be worth it territory depending on what you're doing

88
00:06:35,600 --> 00:06:42,160
the core i5 on the other hand is over 30

89
00:06:39,360 --> 00:06:48,000
faster than AMD's competing ryzen 5 for just 10 dollars more at retail making it

90
00:06:45,360 --> 00:06:51,919
very compelling that is at least if you were already down to spend the extra to

91
00:06:49,919 --> 00:06:56,479
move to ddr5 we're going to have a follow-up comparing ddr4 to ddr5

92
00:06:54,639 --> 00:06:59,759
performance at various clock speeds coming so make sure that you're

93
00:06:57,759 --> 00:07:04,800
subscribed for that how is Intel doing all this though well first is the Intel

94
00:07:02,240 --> 00:07:08,160
7 manufacturing process it's basically just a rebrand of their 10 nanometer

95
00:07:06,720 --> 00:07:13,199
process that we've already seen in laptops but this is its first appearance

96
00:07:10,639 --> 00:07:17,599
without thin and light power constraints and boy did they ever unconstrain it

97
00:07:16,000 --> 00:07:22,639
because another big part of the equation is Intel effectively making support for

98
00:07:20,000 --> 00:07:27,120
multi-core enhancement official what this does is throw the processor

99
00:07:25,120 --> 00:07:32,800
base power rating completely out the window in favor of always running at

100
00:07:29,680 --> 00:07:34,960
maximum turbo power letting the CPU be

101
00:07:32,800 --> 00:07:39,520
unrestrained as long as there's thermal and power budget available it makes such

102
00:07:37,759 --> 00:07:43,440
a dramatic difference to performance that motherboard manufacturers who

103
00:07:41,120 --> 00:07:47,360
enabled this by default in the past were accused of cheating at benchmarks

104
00:07:46,240 --> 00:07:52,319
of course like any overclocking it comes at a cost

105
00:07:50,160 --> 00:07:58,240
the processor base power for the core i9 12900k is 125 watts same as the rest of

106
00:07:55,919 --> 00:08:02,199
the lineup however when loaded down with a long blender render this thing easily

107
00:08:00,720 --> 00:08:08,080
sucked back over 230 watts that is nearly double what our

108
00:08:05,520 --> 00:08:12,800
ryzen 9 chips drew thankfully however this doesn't carry over to gaming where

109
00:08:10,160 --> 00:08:19,440
f1 2021 stayed within the processor base power of 125 watts often remaining lower

110
00:08:16,240 --> 00:08:21,919
than ryzen so as it turns out those

111
00:08:19,440 --> 00:08:26,879
efficiency cores can make a big difference to lighter workloads as for

112
00:08:23,840 --> 00:08:29,599
the core i5 12600k it stayed within the

113
00:08:26,879 --> 00:08:34,560
125 watt processor base power on both the blender workload and our f1 2021

114
00:08:32,399 --> 00:08:39,200
gaming test where it's only a little bit more power hungry than the ryzen 5 5600

115
00:08:36,959 --> 00:08:42,800
x continues to get even more compelling doesn't it something to note though is

116
00:08:40,959 --> 00:08:48,480
that you won't see anything close to this boost forever behavior on a non-k

117
00:08:46,000 --> 00:08:52,399
chip so don't assume that just because you see two cpus with a similar model

118
00:08:50,720 --> 00:08:57,120
number that you will see similar performance especially not at the very

119
00:08:54,880 --> 00:09:02,240
high end to keep thermals under control under these circumstances Intel thinned

120
00:08:59,519 --> 00:09:06,080
out their die even further and even thinned out the soldered thermal

121
00:09:03,839 --> 00:09:10,640
interface material but in spite of their efforts the fact is that anything

122
00:09:08,240 --> 00:09:16,080
drawing that much power that is that small is going to get hot

123
00:09:13,120 --> 00:09:21,600
our nhd15 strained to keep our CPU package below 90 degrees and after about

124
00:09:19,200 --> 00:09:27,600
8 minutes all pretenses that thermals might be manageable were completely gone

125
00:09:24,160 --> 00:09:29,360
for context guys the nhd15 is the top

126
00:09:27,600 --> 00:09:33,760
performing heatsink on the market and it beats out many water coolers at least

127
00:09:32,000 --> 00:09:39,200
the efficiency cores only got to around 70 or 80 degrees so that's a plus i

128
00:09:36,560 --> 00:09:46,560
guess but compared to even the ryzen 9 59 50 x a 16 performance core CPU

129
00:09:44,080 --> 00:09:51,519
this thing packs a ridiculous amount of heat into a tiny area as much or more

130
00:09:49,839 --> 00:09:55,760
than last gen rocket lake with multi-core enhancement enabled again

131
00:09:53,440 --> 00:10:01,279
though it's far more manageable with gaming where f1 2021 pushed our core i9

132
00:09:58,480 --> 00:10:05,519
into only the mid 60s our core i5 for its part never got hotter than around 70

133
00:10:03,440 --> 00:10:10,240
degrees even in our all-out blender render while only hitting 60 in games

134
00:10:08,399 --> 00:10:14,320
it almost feels like Intel sent us the core i5 because

135
00:10:12,000 --> 00:10:18,079
that's the CPU that they really wanted us to review but they knew we'd want to

136
00:10:16,399 --> 00:10:22,640
look at the core i9 so they threw that in the box as well like how much extra

137
00:10:20,320 --> 00:10:27,120
heat is that for what six more FPS from a gaming perspective save your money buy

138
00:10:24,880 --> 00:10:31,120
a water bottle at lttstore.com and it gets even worse for the core i9

139
00:10:29,360 --> 00:10:34,880
these results mean that if you intend to run the CPU at the red line a lot maybe

140
00:10:33,279 --> 00:10:39,519
you're a content creator who does a lot of rendering or you're a developer who

141
00:10:37,120 --> 00:10:44,240
runs a lot of large compile operations you're going to want to invest in a big

142
00:10:41,440 --> 00:10:47,440
cooler both for your CPU and for your computer room during the summer months

143
00:10:45,760 --> 00:10:52,399
and that's a cost that you do have to consider another cost to consider is the

144
00:10:49,680 --> 00:10:57,920
platform we already mentioned that ddr5 won't come cheap but the same is true of

145
00:10:55,120 --> 00:11:01,519
the z690 chipset motherboards that 12th gen cpus require

146
00:10:59,760 --> 00:11:06,880
now there will be long-term benefits to taking the plunge pci express gen 5

147
00:11:04,160 --> 00:11:10,959
which doubles bandwidth over PCIe gen 4 is going to unlock the full capabilities

148
00:11:08,560 --> 00:11:16,880
of the next generation z of graphics cards and the new dmi 4.0 link between

149
00:11:14,160 --> 00:11:20,640
the CPU and the chipset means more high speed networking more high speed

150
00:11:18,480 --> 00:11:23,920
peripherals more storage devices you guys can get the full details on this in

151
00:11:22,480 --> 00:11:27,279
our platform overview which we're going to have linked below what you need to

152
00:11:25,680 --> 00:11:32,320
know now though is should you pull the trigger if an op cooler is in your

153
00:11:29,440 --> 00:11:36,720
budget the core i9 12900k would get the nod from us for both

154
00:11:34,240 --> 00:11:40,399
gamers and for power users that is assuming that gaming was your top

155
00:11:38,240 --> 00:11:48,240
priority but the really interesting chip today is the core i5 12600k

156
00:11:43,519 --> 00:11:51,760
at 320 bucks it might be only a 6 core

157
00:11:48,240 --> 00:11:53,440
