what a roller coaster ride the ryen
0:04
launch has been between the hype and the runup to its launch and AMD's Stern
0:11
refusal to reveal any but the bearest
0:14
details everybody is talking about ryzen
0:19
but could anything live up to this level
0:23
of expectation let's find

0:48
new CPU architecture the ryzen 7 flavor
0:51
of which is launching today it Sports eight cores each with smt so similar to
0:58
Intel's hyperthreading and and boasts a
1:01
whopping 52% Improvement in instructions per
1:05
clock over AMD's previous best and a TDP
1:09
of only 65 to 95 Watts that is a big
1:14
shot across Intel's bow especially considering the ryzen 7 has been
1:19
positioned as performance competitive
1:22
with the Enthusiast class core i7
1:25
6800k and 6900 K 6 and eight core chips
1:30
that Intel rates at 140 Watts so how did
1:35
AMD do it well there's a lot of nitty-gritty that we won't get too deep
1:40
into but here's the tldr AMD's sense Mi
1:44
allows the processor to thoroughly monitor itself accurate to within a
1:49
milliamp molt mwatt and single degre
1:53
celsus 1,000 times per second AMD's
1:57
Precision boost uses that data along on
2:00
with individual testing at the factory
2:03
to determine the ideal clock frequency within 25 mahz steps for Optimal
2:09
Performance even going as far as to boost beyond the rated speed using
2:14
extended frequency range or xfr add that
2:18
to their Infinity fabric scalable high-speed interconnect smarter Branch
2:22
prediction a smarter neuronet inspired prefetch and a more efficient cache
2:27
setup and you've got a very oversimplified nutshell version of
2:33
ryzen of course its performance would be
2:36
meaningless if it weren't priced competitively and uh boy howdy is it
2:43
ever currently the most expensive CPU in
2:47
the range is $499 us which might seem
2:51
like a lot if you compare it to Intel's mainstream Flagship core
2:56
i77700 k at 349 but but AMD reckons
3:01
their top dog is more comparable to the core i7 6900 k a
3:08
,50 chip of course with their history of
3:13
hype training the bananas out of
3:17
mediocore CPU releases we can't just
3:20
take AMD's word for any of this so let's dive straight into the moment you've all
3:25
been waiting for handson with ryzen we'll be pitting ryzen 7 against
3:31
Rivals core i7 6900k
3:35
6800k and 7700k and for fun we've also thrown in
3:40
the core i57600k and dusted off our
3:46
fx8350 with each bench kitted out with a Titan XP and 32 gigs of gskill memory
3:52
shout out at this point to ASUS for providing and helping us learn the ins
3:57
and outs of their Rog CR crir 6 hero
4:01
built with AMD's x370 chipset the First
4:04
new Enthusiast chipset since 2011 for
4:07
AMD and a few special ASUS twists like
4:11
their native USB 3.1 front panel connector comprehensive overclocking and
4:16
tweaking tool set RS syc RGB lighting
4:19
compatibility with am3 and am4 cooler holes and their new s1220 audio solution
4:25
it should be noted that you won't need the more expensive x370 unless Crossfire
4:30
and SLI support is important to you but
4:33
in spite of all of ASUS's help think back to that asterisk about 30 seconds
4:38
ago while I would love to say that the early rumors of am4 having difficulty
4:44
hitting higher memory frequencies were greatly
4:47
exaggerated our 1800 x chip managed a
4:50
mere 2666 MHz with multiple kits
4:54
including the one supplied by AMD any higher no post we hope can be ironed out
5:00
in firmware but with how heavily AMD Zen architecture relies on Fast low latency
5:05
RAM to keep the cores fed our scores for
5:09
synthetic benchmarks in particular might suffer a little bit kicking off our
5:14
testing we have y cruncher at 50 million digits of Delicious Pie the 1800x
5:20
doesn't Faire so well in the single-threaded test but pulls just
5:24
ahead of the 7600k in the multi-threaded one this
5:28
test is RAM intensive though so this lower than expected result isn't
5:32
surprising cinebench being much closer
5:35
to a real world workload paints a more optimal picture with ryzen actually
5:40
beating out the 6900k in the multi-threaded test and coming in just
5:45
under in the single-threaded test CPU
5:48
Mark single-threaded test puts ryzen back at the bottom of our modern CPUs
5:53
while in the overall it slips in neatly between the 6900 and 6800 k moving on to
6:00
szip ryzen killed it coming in well
6:03
above all but the 6900k and PC Mark tells a similar tale
6:08
with AMD's ryzen 7 Flagship outperforming the x99 chips in both
6:14
tests though it should be noted that PC Mark's lightly multi-threaded workload
6:18
definitely favors the 7700 K's blistering clock speeds real bench
6:24
continues the overall trend although we
6:27
see ryzen stumble with heavy multitasking here a potential RAM speed
6:31
limitation while an Adobe Media encoder ryzen 7 and the x99 chips are very
6:38
competitive ad reveals no obvious
6:41
storage bottleneck with similar if slightly lower results to our Intel test
6:45
benches and then moving on to gaming DSX
6:48
mankind divided shows a fairly tight race with ryzen in the middle rise of
6:53
the Tomb Raider sees ryzen rise to the
6:56
occasion to take top spot which it managed to hold in an older title Crisis
7:02
3 moving on to a more Esports oriented
7:05
title we tested csgo specifically with chips that represent the best
7:10
single-threaded performance that Intel has to offer today and that AMD has
7:15
today and before the launch of ryzen
7:19
unsurprisingly if you're running a 240 HZ monitor like this one from ASUS that
7:23
we checked out before and your PC's purpose is pure frame pushing the
7:30
7700k might not look quite as obsolete
7:34
as AMD would like it to for our
7:37
streaming test we gave it a worst case scenario with ashes of the singulari CPU
7:42
focused Benchmark both with and without
7:46
OBS recording in the background we compared the recording performance to
7:51
streaming and it was the same and at
7:54
twitch quality we see that actually none of our CPUs really had a hard time with
7:59
this over just running The Benchmark the
8:02
6900k runs away with this one while the poor fx8350 wishes we'd left it on the
8:08
Shelf compared to Intel quick sync encoding the output from our x264
8:13
testing is quite a bit clearer to my eyes but go ahead and pause the video to
8:18
take a close look at this blown up shot to judge for yourself let us know if
8:22
you'd like us to dig deeper into streaming in the comments below because
8:27
AMD was showing ryzen just butt kicking
8:30
the 7700k so did AMD come out of nowhere
8:34
then Leap Frog Intel on performance and disrupt the market well yes no and yes
8:44
our our testing shows the topend 1800x
8:49
sitting between the 6900 K and
8:53
7700k when it comes to single-threaded Performance and hovering around but not
8:58
quite matching the 6900k in our multi-threaded tests there's no question
9:04
here that heavier users will love AMD
9:08
right now for bringing more affordability to High Core count chips
9:13
without the massive power draw and single-threaded compromises that existed
9:18
before and as for coming out of nowhere with this that definitely happened but
9:24
I'm actually not sure who gets the credit for ryzen 7's disruptive
9:28
positioning is it AMD for coming in and giving the
9:32
consumer nearly twice the performance per dollar value of a
9:37
6900k or is it Intel for stubbornly
9:41
refusing to acknowledge the benefits of more cores for the mainstream consumer
9:46
and creating a confusing product stack where bang for the buck varies so
9:52
dramatically within their own products they handed AMD's marketing department a
9:58
lot of Firepower here by allowing them to bang the twice the value of the 6900k
10:06
drum while conveniently ignoring that Intel also produces chips that deliver
10:12
twice the value of a 6900k or
10:16
more I guess that's neither here nor there though the major takeaway here
10:22
isn't that the 1800x devoured all in its
10:26
path but that as AMD used to be be so
10:29
good at doing they've identified a market segment where no directly
10:35
competing product really exists and engineered a solution enthusiasts
10:41
looking for something bigger than a
10:44
7700k but not wanting to lose single-threaded performance and eat
10:48
nothing but instant noodles for a year by stepping up to a 6900k will be
10:53
delighted with the ryzen 7 lineup
10:57
meanwhile professionals who don't need RAM slots or Thunderbolt will also find
11:02
a CPU that performs better than Intel's
11:06
mainstream while lacking a couple of extras very appealing and all of this
11:11
ignores too the six core and four core
11:15
Zen core solutions that are coming later on this year to disrupt Intel's Core i5
11:21
and core I3 products so AMD fans Rejoice
11:25
then with ryzen AMD is back in a big way
11:29
and and even if you're on team blue you should be happy too because competition
11:33
is always good for the consumer do you feel like your cellular
11:37
provider doesn't give a rat patoot about you who am I kidding of course you do so
11:43
check out Ting we've got a link in the video description these guys are all
11:46
about customer service when you call them you do not speak to a robot there
11:51
is no phone tree you get put through directly to a person and somehow they
11:56
managed to do that with a very affordable able average Ting bill of
12:01
only $23 per month per device for their
12:04
customers they do this by making everything pay for only what you use so
12:11
all you do is head over to their savings calculator that's lin. ting.com we''ve
12:15
got that link below you enter your last few bills you enter how much you're
12:19
paying now and it spits out how much you'll save by switching to Ting and
12:24
they've actually got lower data rates across the board now so don't hesit
12:29
check it out today and if you switch you'll also get $25 in service credit or
12:34
towards a new device using our link so
12:37
thanks for watching guys if this video sucked you can dislike but if you liked
12:41
it hit the like button get subscribed maybe check out the link to where to buy
12:44
the stuff we featured in the video description while you're down there
12:47
we've got a merch store and a community for as well which you should check out
12:51
and now that you're done doing all that stuff you're probably wondering what to watch next so check out that little uh
12:57
video player thumb nail thing go ahead click it there'll be another one of our
13:01
videos there you'll like
13:06
it no that was the computer okay well that
13:12
was exciting this is probably still okay
