ryen 5 many of you have been waiting patiently or impatiently for its big
0:06
debut something which we stop what stop
0:10
you're going to get wrecked look at these
0:13
comments what is this who are you H I'm
0:17
I'm you from the future if you release
0:21
this simulation of AMD rise and performance everybody's going to hate
0:25
you simulation what simulation I've Got ryzen 5 right here no oh you don't
0:31
understand I just wait this is the
0:35
review Great Scott I've got to go I set
0:39
the dial
0:48
wrong welcome then to our ryzen 5 review
1:03
we're opening up a new merch store you can check out some of our new gear today
1:07
at the link in the video description as we've mentioned before
1:12
AMD is aggressively targeting Intel in
1:15
terms of core count and pricing packing
1:19
Enthusiast features into their CPUs in order to undercut Intel's Core i5 and
1:25
core i7 with their appropriately named ryzen 5 and ryzen 7 CPUs whether they
1:33
succeeded or not we'll address a little bit later because first we need some
1:38
boring technical details both ryzen 7 and ryzen 5 which
1:44
launches today come with two of what AMD
1:48
calls CPU complex or
1:52
CCX which is four processing cores
1:55
attached to 8 Megs of high-speed cache
1:58
these CC X units communicate with each
2:02
other over an allnew bus that AMD calls
2:06
Infinity fabric the difference between
2:10
them is that ryzen 5 comes with two or
2:14
four individual cores disabled through a
2:19
process called binning whereby faulty or
2:22
underperforming cores are shut off then
2:26
the chip is sold at a lower price so if
2:29
we line up our ryzen 5 and ryzen 7 CPUs
2:33
we can see that our 1600x is basically a
2:38
cut down 1800x while our 1500x is
2:42
probably a cut down 1700 with tweaked
2:46
clock speeds what's unusual about AMD's
2:50
approach here though is that they've disabled the cores symmetrically to make
2:55
hex core and quad core models the
2:58
disadvantage is that the quad core model
3:02
may suffer some performance penalty for
3:05
not having all of its cores on the same
3:08
CCX but the advantage is that every
3:12
ryzen 5 gets a massive 16 megabytes of
3:18
cash and all the other features are
3:21
there too Precision boost xfr
3:25
simultaneous multi-threading neuronet
3:28
inspired Branch prediction so when you start to think about it then
3:32
how many cores do you really need and if
3:35
the answer is any fewer than eight then
3:38
ryzen 5 starts to sound like a really
3:41
good way to save a few bucks let's talk
3:45
about the test AMD included an MSI b350
3:49
Tomahawk motherboard in our testing kit but we used our Crosshair 6 hero instead
3:55
for the sake of consistency and on that subject we actually re tested all of our
4:02
AMD chips with the latest BIOS revision
4:05
and a new kit of g-skill flarex RAM
4:09
which means that we are finally able to give you guys results at ddr4 3200
4:15
speeds woo this along with the rest of our test
4:20
stable should give us a great picture of
4:23
how ryzen 5 Stacks up for extra credit
4:26
we also tested our ryzen 5ivs with a 4
4:29
GHz overclock the best that we could achieve on both of the chips with air
4:35
cooling oh and uh by the way our simulated 1600x we threw that in there
4:40
too let's kick things off with gaming
4:44
thanks to their native overclocking support both of our ryzen 5 chips
4:49
managed to pull off some impressive numbers next to their team blue
4:53
competitors although it is worth noting that the
4:57
7600k can overclock two games like rise
5:02
of the Tomb Raider and doom in open mode
5:05
tend to devour instructions per clock giving our Intel benches a lead unless
5:10
we overclock on ryzen which sometimes
5:13
actually accounts for some major gains in performance here now that's weird
5:19
what gives with Team blue your cash is
5:23
generally going to remain at the same speed unless you overclock it separately
5:29
but as it turns out ryzen's cash just
5:34
loves getting as much CPU time as it can
5:38
which favors their Infinity fabric connected CCX architecture along with
5:43
their High Core counts so with many
5:46
cores and higher clock speeds AMD's cash
5:50
actually becomes more efficient how do we know because when we compared cash
5:56
benchmarks between our stock and overclocked chips we found major
6:00
improvements thanks to our overclocks that look in line with the differences
6:05
between the two chips core counts I mean
6:09
overclocking our 7700k we saw performance fluctuate a bit
6:14
but nowhere near this much so this seems
6:18
to explain some of what we're seeing here in these gaming
6:22
tests good news for AMD fans looking to overclock then because overclocking adds
6:27
to multiple perform performance metrics
6:31
speaking of which in our synthetic tests we can see that ryzen continues to
6:36
dominate Intel's mainstream platforms when it comes to multi-threaded
6:40
Performance what's even more interesting about these results however is that the
6:45
ryzen7 1700 frequently ends up matched
6:49
by our overclocked 1600x which becomes all the more
6:54
impressive when you consider the performance per dollar that this
6:58
translates to thanks to the $80 price
7:01
difference between the two chips speaking of performance per dollar team
7:06
red and team blue are neck and neck in
7:10
this all important metric a small as
7:14
side here by the way if you've been paying attention our simulated ryzen
7:18
5600 x has also kept up very well with
7:21
our real 1600x finally let's talk about thermals
7:27
something we weren't able to simulate now that we're equipped with AMD's
7:30
wraith Max and wraith Spire coolers we
7:33
can test our ryzen 5 chips with both stock and aftermarket cooling so for
7:39
Giggles we threw our spire on our overclocked 1600x and managed to
7:45
maintain our performance at reasonable
7:48
if unexceptional temperatures so aftermarket cooling is still recommended
7:52
for overclocking even on ryzen's four
7:56
and six core variants which leads us to
7:59
our conclusion then since its launch
8:02
AMD's new platform has been changing
8:05
almost daily we're constantly learning
8:09
new things about how it does perform how
8:12
it's supposed to perform and why and
8:16
with ryzen 5 AMD's future becomes much
8:19
clearer thanks to software and firmware
8:22
updates that continue to improve ryzen's
8:25
performance and stability with these numbers and pricing Intel may be
8:31
starting to sweat a little bit remember too that we used an x370 board but you
8:37
could save a fair bit on the platform overall by stepping down to b350 if you
8:42
don't need SLI or even lower if you don't plan to
8:46
overclock now to be clear ryzen doesn't
8:50
overclock like crazy the platform bugs
8:53
aren't quite fully ironed out and it still isn't the clear of Far and Away
9:00
performance King that a lot of people wanted it to be but what they have done
9:06
when you factor in the entire Suite of tests is deliver just as much bang for
9:12
the buck as team blue right now and that
9:15
is a very good
9:18
thing do you have two computers do you
9:22
have two keyboards and two mice all over your desk so that you can actually use a
9:26
four menion two computers well that dumb
9:29
because Synergy exists and it allows you to share one Mouse and one keyboard
9:35
seamlessly between two or more computers
9:39
so you'll no longer confuse which one is
9:42
for which and which one goes with what one it's awesome they've got a basic and
9:48
pro version with a one-time payment for Lifetime access and the features include
9:52
clipboard sharing between the computers dragging and dropping files between the
9:56
computers the ability to set up hot keys and more it even works on Windows Mac
10:02
and Linux and you can use our Link in the video description to save 25% on
10:07
Synergy today so thanks for watching guys if you dislike this video you can
