AMD's new Verizon 4000 laptop processors
have improved Vega graphics built-in but
how does this actually compare to the
last generation in games let's compare
and see what the differences are in
gaming performance with the old and new
Vega mobile graphics AMD nerded that
rather than using their latest Navi
architecture with Rison 4000 they would
instead use an improved 7 nanometre
version of vague or AMD determined that
Navi graphics would not have the
necessary optimizations ready in time so
they decided to stick with the Vega
architecture and improve it one of the
big differences with seven nanometer
Vega of course outside of the benefits
going from 12 nanometer to seven
nanometer is that they actually cut back
the number of compute units but instead
boosted up the clock speed according to
AMD
these improvements result in 25% higher
peak graphics clocks 2 times wide data
fabric interface for power efficient
data transfer graphics low-power state
the transition optimization and 77%
higher peak memory bandwidth as the Vega
graphics essentially utilized the
laptops ddr4 memory this improved memory
bandwidth would in part be from AMD's
move from ddr4 2400 with Rison 3000 to
ddr4 3200 or lpddr4 x40 266 with Verizon
4000 all things considered the end
result is that per compute unit the new
seven nanometer Vega ends up being 59%
faster when compared against 12
nanometer Bega from the last generation
according to AMD let's put this to the
test by comparing two laptops I'll be
using the msi alpha 15 with the horizon
737 50h a 35 watt part which represents
the best mobile chip MD will offering
from the previous generation and this
has the older 12 nanometer vago I'll be
comparing with the assist g14 with the
risin 940 900 HS again a 35 watt part
and is one of the best Rison processors
from the new generation and makes use of
the newest 7 nanometre vago i thought
this would be an interesting comparison
because both processors have the same 35
watt TDP and I don't have a 4900 H at
the
however as we can see here both the H
and H s have the same number of compute
units and graphics frequency anyway with
all of that in mind let's get into the
gaming benchmarks both laptops were
tested with the discrete GPU disabled
through device manager let's start out
with CS kirk as this is a game you can
actually get away with playing on the
Vega graphics at 1080p I've got the
older 12 nanometer Vega represented by
the red bars and the newest seven
nanometer Vega shown by the purple bars
at all setting levels it's a clear win
for the newer chip however the
performance difference is larger at
lower settings where the 4900 HS was 45%
faster than the 37 50 H at lower
settings there will likely be a greater
difference as these tests are also CPU
bound and the 4900 HS destroys the 37 50
H in CPU bound tasks at max settings
where we're hopefully more GPU bound the
new Vega graphics were 38% faster dota 2
was also performing a fair bit better
with the new 7 nanometre Vega graphics
from the 4900 HS at Ultra settings where
we're likely to be more GPU bound the
new Vega graphics were 18% faster than
the older 3750 H at low settings though
the new chip was a much higher 38%
faster but again this is more likely to
be showing differences between CPU
performance rather than Vega specific
performance Fortnight was tested using
the replay feature with the exact same
replay on each laptop at minimum
settings the newer 4900 HS was a massive
67 % faster even the 1% low performance
was dominating the average from the 3758
but yeah again that's probably more of a
CPU focused test at epic settings
neither were offering a playable
experience however the new graphics was
still 33% faster the new graphics played
quite well at medium settings which was
averaging above 60fps and for context
the old graphics was similar with low
settings
overwatch was tested in the practice
range so the FPS is a little above
actual gameplay but it allows me to
perform the exact same test pass on each
laptop in this test I found low and
medium settings to play well enough with
the 37 50 H meanwhile though the 4900 HS
was outperforming birth even at high
settings at epoch where
Zoomers GPU Bellmer the newer Vega
graphics with 32% faster
I found it particularly interesting that
even the 1% lower performance from seven
nanometer Vega was higher than the
average FPS from 12 nanometer Vega at
Alban medium settings where it was very
close
I've also tested a few other games as I
wanted some more data however I only
tried these at lowest setting presets as
in many cases they were hardly even
playable there Rainbow six siege was
tested with the game's built-in bench
mark using balkan I've only tested low
settings here but the one percent lower
from 7 nanometre Vega was ahead of even
the average from 12 nanometer Vega while
the average FPS was 49% faster but again
lowest settings so a chunk of this would
be down to CPU performance differences
rather than explicitly Vega table G was
tested using the same replay on each
machine with very low settings the 4900
HS laptop was a massive 55 % faster in
terms of average FPS but again a lot of
that is probably not specific to the
Vega difference shadow of the Tomb
Raider was tested with the game's
benchmark at lowest settings where the
4900 HS was 35% faster but I wouldn't
say either are playable with these
results The Witcher 3 also saw a very
similar difference with the 4900 HS 34%
faster in average frame rate when
compared to the 37 50 H these are the
differences overall eight games tested
with the minimum setting preset on
average the riser 940 900 HS was 44%
faster than the horizon 7:30 750 H in
terms of average FPS as mentioned
throughout the video as this is with the
lowest possible presets a fair bit of
the performance difference is likely
down to other differences such as the
improvements with center over the older
Zen plus here's a quick look at the 1%
lower difference on average results were
similar granted it's not directly
comparable as this graph doesn't account
for shadow of the Tomb Raider because I
can't get one percent load data out of
that test these are the performance
differences between the for eSports
titles with the highest setting preset
in use in theory we're more GPU bound
here so we're probably looking more at
the differences between seven nanometer
and 12 nanometer Vega here assuming so
on average seven nanometer Vega is
almost 30% faster when compared to 12
nanometer vague
unfortunately a dirt have more Dada as
most other games are honestly too heavy
to be run at max settings 1080p I could
have tried 720p but I didn't test it out
prior to sending the g14 off to hardware
and boxed I only had a brief look at
power draw from the wall in csgo with
max settings the g14 was using around 83
watts while the alpha 15 was using 78
watts so 6 percent more power seems fair
for the large performance boost in that
game though there could also be other
differences at play as they are
different laptops I really doubt that
we'll see a laptop with a 4900 HS that
doesn't have some form of Radeon or
Nvidia discreet graphics so it's
probably fairly unlikely you'll be using
Vega graphics in the 4900 HS for gaming
so I guess that makes this more of a the
science test to see what the differences
are between best-case lost gen and best
case current gen I think with Vega
graphics less demanding titles are more
likely to be played anyway and I think a
30 percent performance jump in one
generation is fairly impressive assuming
the gains are similar on lower end
laptops where Vega is actually more
useful this could certainly offer a
playable experience for thinner and
lighter laptops in many titles it'll be
interesting to see how the lower powered
Vega parts stuck up hopefully I can get
my hands on all variants and do a big
performance comparison in future let me
know if you'd be interested in something
like that I'm honestly not sure how many
of you guys only game on the integrated
graphics compared to discrete graphics
and of course let me know what you
thought of the performance difference
between the older 12 denim 8 of a go
architecture and the newest 7 nanometre
