we're going to be talking about AMD's phenom CPU
0:04
where am i my why is my shirt black
0:07
like hey hey whoa oh wait oh what where
0:12
am i now oh i got my own media group
0:16
cool oh check this out i ride one of these
0:21
sick
0:26
oh this must be my my office
0:32
oh look at this thing is this this a CPU
0:38
wow look at the size of it
0:43
ripper too could the is it could it be
0:48
the future
0:51
no no it's not the future it's today it's the AMD ryzen
0:57
threadripper ii 2990wx and it is right now and our video about
1:02
it is brought to you by nci
1:06
i fix it ifixit's new mahi driver kit
1:09
includes their one quarter inch aluminum screwdriver handle with a magnetic bit
1:14
socket knurled grip and swivel top with 48 driver bits check it out at the link
1:18

1:28
so young lioness there came from a world where the Intel core 2 and AMD phenomx 4
1:34
series of quad-core processors had the
1:38
highest core counts among consumer products but in the 10 years since then
1:43
the situation has changed a lot with AMD
1:47
launching an industry shaking 16 core
1:50
Threadripper processor last year and then following it up today with the
1:55
debut of the 2990 wx a 32 core
2:00
64 thread successor now they've created a ton of excitement
2:06
amongst both consumers and professionals
2:09
and they have sown a lot of discord with
2:12
their competition over at Intel who have reacted to the disruption with their own
2:17
high-end desktop chips based on the same dna as their xeon server lineup and then
2:23
this weird like 28 core demo thing that
2:26
they were doing at computex this year and then shortly afterward tried to hide
2:32
anyway hype train aside though one thing that
2:36
we know about threadripper 2 before we
2:40
even start testing it is that this
2:43
is not a gaming centric CPU i mean even
2:47
ignoring the 1300 and eighteen hundred
2:51
dollar price tags when we dig even a little bit further
2:55
into the specs we find that the wx series so these are the two new high-end
3:01
ones doesn't turbo up as fast as its ex
3:06
brethren the direct zen plus replacements for last year's thread
3:11
ripper one of course with that said we're still going to run
3:15
some gaming benchmarks anyway so normally we actually breeze by our test
3:21
benches but this time there are a couple of important notes so AMD has created a
3:27
really solid upgrade path for their x 399 customers by allowing existing
3:32
boards like this zenith extreme from ASUS to run the new chips with nothing
3:37
but a BIOS update with that said ASUS
3:40
did have some concerns about overclocking and up to 200 250 watt chip
3:47
on boards that weren't necessarily designed for that so they equipped us
3:51
with their rog zenith extreme cooling kit you shouldn't need this kind of
3:55
thing for stock operation or if you have excellent air flow over your socket area
4:00
already but if you're overclocking we would
4:04
strongly recommend it all right the first big surprise in our
4:07
gaming testing was discovering that threadripper 1
4:11
is actually faster in some cases in
4:15
spite of threadripper 2's higher clock speeds
4:18
even after multiple runs these results persisted which might seem like some
4:24
kind of a mistake but as it turns out the less sophisticated first generation
4:30
precision boost so that's AMD's dynamic clock speed optimization engine kept the
4:35
core clocks higher more often with precision boost 2 more aggressively
4:40
utilizing its intermediate clocks instead of being either full out or
4:45
clocked down so we actually ended up losing some raw speed but what we're
4:50
getting back in return is more consistency
4:53
another thing that impacted gaming is uma versus numa memory access modes
5:00
now it's quite a bit more complicated but in layman's terms uma is typically
5:05
better for multi-threaded workloads thanks to its more consistent memory
5:09
bandwidth while pneuma can come out ahead sometimes thanks to a small
5:14
latency advantage in lighter ones it
5:17
should be noted that only the x series allows you to decide which mode you
5:21
prefer wx only runs in numa mode this
5:24
was to retain intergenerational compatibility and i would say that there
5:29
are probably some creator by day gamer by night folks out there who are going
5:34
to be pretty pleased with the upgrade path that AMD has provided here i mean
5:39
the 2990 wx isn't
5:43
far and away the fastest CPU in every
5:46
test that we ran blender which leverages Intel's avx 512
5:50
extensions is a notable exception and single threaded tests are obviously not
5:54
its strong suit but this this is one
5:58
powerful piece of silicon even Intel's marginally more expensive 7980xe
6:04
is no match when threadripper2wx
6:08
gets to stretch its legs now on the subject of stretching them
6:13
let's uh try some overclocking shall we
6:16
now you can still overclock threadripper
6:19
2 manually but in theory anyway AMD's
6:22
precision boost overdrive allows the user to simply
6:27
set a higher power budget and then watch while precision boost 2 and xfr so
6:32
that's extended frequency range too do all the heavy lifting only some of our
6:38
workloads actually improved in performance while others straight up
6:42
regressed we think this has to do with some kind of weird thermal limit as
6:47
indicated by the identical 68 degree t-die reading at both stock and
6:52
overclock speeds in spite of our beefy cooler but that may require further
6:56
investigation let us know if you'd like to see a dedicated threadripper 2
7:00
overclocking video for now i'm just going to grab this grab this baby
7:05
here's what we can say 32 cores in a consumer or prosumer or
7:11
workstation chip whatever you want to classify it as
7:15
sounds amazing it is exactly the
7:18
headline that AMD needs as a company right now to gain valuable what's called
7:23
mind share where normal consumers are more likely to run out and buy normal
7:28
ryzen chips because the world record holders and the influential content
7:33
creators that they admire are using AMD
7:37
in the real world though the potential market for a product like this
7:42
is pretty limited now the 2990 wx
7:45
is the high-end workstation king
7:48
but you need workloads like heavy virtualization or 3d rendering or gas
7:54
exploration that take advantage of it otherwise honestly speaking you'd be
8:00
better off spending half as much on a
8:03
2950x the 16 core drop in replacement
8:07
for the older 16 core but now with zen plus or looking at Intel's lineup if avx
8:13
512 support or single threaded performance are also important to you
8:18
but maybe at the end of the day it doesn't matter who it's for
8:22
maybe this was just about building an amazing piece of technology and then
8:28
patiently waiting for the use cases to show up because
8:31
i mean if there's anything that the history of computing has shown us it's
8:35
that if you breed a faster horse someone somewhere is going to build a
8:41
more challenging course
8:44
speaking of building something massdrop has gone from just being a place for you
8:49
to buy stuff to a place where you buy exclusive amazing collaborative products
8:53
and the massdrop x hifiman he 350
8:57
headphones use new dynamic drivers different from what was used in the at
9:01
300 resulting in a more neutral sound signature they feature a comfortable
9:05
headband the lure ear pads and a detachable cable and they ship within
9:09
two to three days check them out today at the link in the video description
9:14
so thanks for watching guys if this video sucked
9:18
it's hard to be an Intel fanboy today isn't it
9:21
so you guys know what to do but if it was awesome get subscribed hit that like
9:25
button or check out the link to where to buy the stuff we featured in the video description also link down there is
9:30
where merch george has cool shirts like this one and our community forum which
9:33
you should totally join
