Get a Job. - Radeon
VII Review #Helpful Post
you
know what Andy fans I actually feel
bad
for you for ten years you've had to
give
your hard-earned money to either
Intel
or Nvidia or both if you wanted to
build
a top-of-the-line gaming r8 AMD
just
hasn't been able to get both their
CPU
and GPU business units firing at the
same
time but perhaps that all changes
today
AMD
stunned the industry as a whole when
they
unveiled their GeForce RTX
competitor
the Radeon seven one month
ago
and then they stunned me in
particular
when it arrived in our office
on
time for their target launch date of
February
7th it isn't it beautiful it is
and
it's got RGB but is it good enough
to
pressure Nvidia to lower their higher
than
ever prices for enthusiast gaming
GPUs
well we'll find out soon thanks to
war

online
game for sponsoring this video

let's
begin with the bad news for those
of
you who like living on the bleeding
edge
AMD 7 nanometer Vega offering has
no
support for ray tracing nor does it
have
any kind of equivalent to invidious
deep
learning optimized tensor course
now
AMD has said that they're looking
into
implementing something similar to D
LSS
super sampling in the long term
using
Microsoft's new direct ml API but
only
time will tell if they get that
done
and what kind of performance hit
we'd
be looking at what we've got here
is
actually if you look closely it's
right
in the name basically a die shrunk
and
optimized Vegas sequel but that's
not
necessarily a bad thing let's take a
closer
look right out of the gate it's
clear
that AMD considers cooling to be
of
the utmost importance while the
previous
gen Vegas 64 used a blower
design
the Radeon 7 3 cooling fans on a
large
not to mention heavy vapor chamber
cooler
just like it to our TX
competitors
speaking of which not only
as
the Radeon 7/8 taller card than the
RT
X 2080 that AMD has positioned it
against
it's also got twin 8 pin PCI
Express
power connectors to allow it to
suck
up more juice come to think of it
that's
kind of weird normally die
shrinks
come with a power savings ah
right
so as far as we can tell they
basically
put their entire power budget
savings
towards cranking the clock
speeds
up on this thing interesting so
ok
then an overclocked and evolved Vega
I
can dig it did they do anything else
to
differentiate it from last gen oh
right
yeah they did how does double the
HBM
2 memory at double the bandwidth
sound
to put that into perspective the
Radeon
7 has faster memory than any of
the
GTX Titans or r-tx Titans for that
matter
but will that massive memory
bandwidth
and significant core clock
increase
make up for the loss of a
handful
of stream processors and will
its
resulting overall performance make
up
for the lack of rate
singer/dancer
course at this price to
find
out we've brought out both our
Intel
and AMD gaming test benches to pit
it
head-to-head against not only the
r-tx
twenty eighty and twenty atti but
also
the Vegas 64 to see just what
impact
those compromises had on the
cards
performance so as is tradition by
now
AMD seems to do worse and DirectX 11
titles
than Nvidia but maintains an edge
or
trades blows with team green whenever
DirectX
12 is in play which extends to
Far
Cry 5 and especially csgo where our
RTX
2080 gets beaten by a pretty
significant
margin when we throw
synthetics
into the mix we see a
reversal
of the DirectX 11 and 12
performance
from earlier which come to
think
of it is why we stopped using
synthetic
benchmarks years ago I mean
this
isn't even this isn't even
representative
of real-world performance
Anthony
was the one who brought them
back
I think I'm gonna have a word with
them
when we're done this video about
just
killing them again once and for all
anyway
moving on to productivity we've
got
more tradition with AMD's Radeon
seven-pole
ahead of even the 2080 ti in
longer
blender renders while falling far
behind
in v-ray in Lux mark the seventh
straight
up embarrasses Nvidia across
the
board but then inspect view perf
which
gives us a broader look at its
workstation
chops we've got a game of
leapfrog
going on
so
workloads that are particularly
memory
hungry like katiya energy medical
and
siemens NX show pretty strong wins
for
AMD but in some cases again eclipse
even
the 2080 ti while nvidia takes the
crown
in workloads that require raw
compute
strength sometimes again by
broad
margins when we look at thermals
things
get a little interesting now
traditionally
GPU temperatures are
measured
by a sensor at the edge of the
die
and this is the temperature we're
showing
you guys right now but AMD has
actually
doubled the number of sensors
on
the radio in seven and both the fan
speed
and boost controls are mated to
what
they're calling the junction
temperature
with a target of 110 degrees
Celsius
so the TLDR then is that the
junction
is
highest
reading out of all 64 sensors
and
they claim that by doing things this
way
they can squeeze more efficiency out
of
the GPU unfortunately that also means
that
the fans begin to ramp up much
sooner
than you might be used to at a
junction
temperature of 95 degrees and
he
does say though that you can increase
this
to 105 in their wot man software
without
any risk of damaging the card
speaking
of wot men we found that we
couldn't
really push the core clocks up
at
all without running into issues with
either
early thermal throttling or
general
instability so this supports our
pre
overclocked hypothesis but we will
have
to wait for more mature drivers and
for
partner boards with more robust
power
delivery before we can say
anything
conclusively so verdict time
then
given our results and the Radeon
seven
700 dollar price tag we're kind of
inclined
to agree with Nvidia CEO and
curiously
dr. Lisa Seussical Jenson
Huang
it's a bit underwhelming yes for
the
same price as a reference RT X 2080
you
get similar performance in
traditional
games but and videos overall
feature
set is simply more robust maybe
you
don't care about real time rate
racing
or maybe you don't care about
GeForce
experience or maybe you don't
care
about Nvidia superior Hardware
h.264
encoder but take it all together
odds
are you'll care about at least one
of
invidious features so in our minds
then
the Radeon 7
to
beat the RT X xx 80s price not match
it
and the frustrating thing is that if
it
weren't for the massive HBM 2 frame
buffer
they probably could have the word
on
the street is that just shy of half
of
the cost of this card is in that 16
gigs
of memory that depending on the
game
might never be utilized more than
75%
now if we had to guess we'd say what
probably
happened here was that rather
than
re-engineering a gaming tuned card
with
eight or twelve gigs of memory and
I
don't know more stream processors or
something
am
recycled
their enterprise compute card
the
radio and instinct mi 50 which would
also
explain the excellent productivity
numbers
whatever
the reason though that
compromise
means that while the Radeon
seven
is an excellent maybe even ideal
card
for content creators by day gamers
by
night or really anyone who uses
OpenCL
a fair bit the value proposition
against
team green is merely okay for
peer
gamers don't get me wrong this
gives
us a choice in the market for sure
and
I'm I'm super glad that AMD released
it
today it's just not quite the price
or
performance disrupter that we were
all
hoping for in the wake of invidious
stiff
r-tx tax and as it stands it looks
like
we're just gonna have to live with
digging
