over the last five years it seems like pretty much
everyone has uh let's say noticed Intel's consumer
divisions tick tick tick tick eventually talk
approach to generational performance improvements including folks at AMD
but then on the surface AMD seems to have pulled a page
right out of Intel's playbook with their second generation AMD ryzen desktop
processors but is there more to these than meets
the eye well i'm going to let you know after
this painful segue to our sponsor private internet access private internet
access is the vpn service that encrypts all of your internet traffic and uses a
safe protected ip it's got tons of other useful features and you can check it out
at the link below
so what's the deal here is AMD replacing ryzen 3 ryzen 5 and ryzen 7
with ryzen 2. not quite
while these are second generation the ryzen 7 2700x
and the ryzen 5 2600x clocking in at 8
and 6 cores respectively are not technically zen two
that's not going to come until later so what we're getting now are higher boost
clocks with xfr applying to all cores
and this one's pretty exciting up to a 34
improvement to cash latency with AMD claiming a theoretical three percent
performance bump from that second point alone
we're also getting up to dual channel ddr4 2933 support on the brand new
x470 chipset motherboards which from
even our early testing translates into much better compatibility with
high-speed memory kits so
all of this adds up to something that AMD is calling
zen plus based on a tweaked 12 nanometer
process that's been fined tuned to push rated clock speeds higher without
increasing the rated power consumption now of course we're gonna have to test
all these claims so while we wait for this to uh
rise ah
it's a yeast joke let's go over our test setup
we'll be using both Intel's latest and AMD's previous gen consumer processors
which ah it's done already
go ahead and cut oh my god this joke is so i'm sorry that whole thing with the
oven was just a lead into a joke about
delicious rison crust why don't we just get into the benchmarks
starting with our gaming stuff
and yes more terrible puns how surprising
ryzen's second gen is ever so slightly
faster than ryzen first gen deus ex mankind divided barely cared far cry 5
actually got 5 to 7 more FPS and cs go
actually this one was a standout very nice
the differences though are less noticeable in 3d mark and unigine
superposition putting second gen close enough that we technically observed
higher numbers on our first gen chips
and of course when it comes to gaming Intel still steals the show
now let's move on to productivity
here things take a more dramatic swing so our 2700x
absolutely creams the last gen 1800 x
and r testing with significantly higher scores in cinebench and ASUS real bench
and shaving a cool 1 minute 11 seconds
off the classroom render time in blender the 1800x already beat out the core i7
8700k in most of these so the gap then
is that much wider this time around impressive
and it looks like at least some of this is due to the improvements to cache
latency with our testing in ida 64 showing a pretty significant improvement
of around 25 with higher bandwidth and improved
memory latency to boot of course what would a review of a new
CPU be without overclocking results
let's go to level three bam
so our 2600x still didn't want to play ball with our
pre-release firmware but our 2700x with
the auto tweak feature gave us predictably better results although
these gains are mainly limited to highly threaded workloads
lightly threaded or gaming workloads understandably actually suffer slightly
compared to the 100 megahertz faster stock xfr clocks
power consumption is still higher than coffee lake but that's not really a
surprise what is interesting is that under load our new chips are more power
hungry we think because precision boosts 2 is keeping the CPU at higher speeds
more often this also translates into higher
temperatures which means we wouldn't really recommend doing a ton of
overclocking with your stock cooler as cool as the new wraith max RGB coolers
might be so then at 329 for the high-end ryzen 7 2700x
and 229 for the six-core ryzen 5 2600x
both of them 30 dollars more than their non-x counterparts AMD has managed to
claw back a bit of the bang for the buck proposition that they enjoyed with
ryzen's first generation release and perhaps more importantly
even though this is a new CPU and chipset the obvious stability issues
with high speed memory in particular that prevented us from making a clear
recommendation last time around are gone
so let's not kid ourselves this is every bit as incremental as Intel's move from
sky lake to kaby lake and we are disappointed that it's not zen 2 yet
but second generation ryzen is a bit more
worth your money than last time which is a good thing
you know what else is a good thing mass drop the concept is pretty simple
to understand the more people who commit to purchasing a certain product the
lower the price of that product goes and today we're talking about the akg k7xx
configured by mass drop these are open-backed headphones with large cushy
earcups that have been tweaked to deliver a wide locationally specific
sound stage that puts you closer to the source they feature a genuine leather
headband memory foam ear pads with velour covering a two-year warranty
service by akg and they ship out in two to three days so check them out at the
