- 🔄 For those looking to game and also require 16 cores, the 7950X3D is an option, but the gains from the 3D V-Cache are not as significant as with the 5800X3D, making the latter a better value for some users.
Q & A
What is the significance of the 3D V-cache technology in the Ryzen 7000 series?
-The 3D V-cache technology, introduced with the 5800X3D, is significant because it adds an additional 64MB of L3 cache to the CPU, improving gaming performance by reducing latency and enhancing frame rates. AMD has now integrated this technology into the Ryzen 7000 series, including the 7950X3D, 7900X3D, and 7800X3D.
How does the 7950X3D compare to the 5800X3D in terms of gaming performance?
-The 7950X3D offers slight improvements in gaming performance compared to the 5800X3D, but the gains are minimal. In some cases, such as Modern Warfare 2, the 5800X3D is actually slightly faster. Overall, the 7950X3D is faster, but the difference is often marginal.
Why might the 7800X3D be a better option for gamers compared to the 7950X3D or 7900X3D?
-The 7800X3D might be a better option for gamers because it offers the most 3D V-cache enhancement for the money. Since AMD's latest chipset driver only uses the fastest 8 cores for gaming, the additional cores in the 7950X3D and 7900X3D are often underutilized during gaming, making the 7800X3D a more cost-effective choice.
What impact does the new chipset driver have on gaming performance in the 7950X3D?
-The new chipset driver disables the non-3D V-cache CCD when gaming, ensuring that only the cores with the extra L3 cache are used. This optimizes gaming performance by focusing on the fastest 8 cores, which improves efficiency during gaming loads.
How does the 7950X3D handle power consumption and temperature management?
-The 7950X3D has lower power consumption, pulling just 76 watts while pushing out 1000 FPS in games like Valorant. However, its temperature management is somewhat unusual, with the chip quickly reaching 89 degrees Celsius under load, even with a 360mm cooler. The CCD with the 3D V-cache heats up significantly more than the non-3D CCD, indicating uneven heat distribution.
In what scenarios does the Intel 13900K outperform the 7950X3D?
-The Intel 13900K outperforms the 7950X3D in certain games, such as Red Dead Redemption 2 and Doom Eternal. In these cases, the extra L3 cache of the 7950X3D does not provide a significant advantage, allowing the 13900K to edge out slightly in performance.
What are the main trade-offs when choosing between the 7950X3D and the standard 7950X?
-The main trade-offs between the 7950X3D and the standard 7950X involve gaming versus productivity performance. The 7950X3D is better for gaming due to its 3D V-cache, while the standard 7950X is better for multi-threaded workloads like rendering and encoding, where it can sustain higher clock speeds and performance.

how much faster can gaming CPUs really
get because lately it seems like the
progress has been really really slow
while the rendering and encoding side of
things is becoming absolutely unhinged
the gains when it comes to frame rate
and gaming are far less inspiring well
let's see if the 7950x3d can change that
AMD have taken the secret Source from
the 5800x3d which is that 3dv cache
stacking and added that here to ryzen
7000 finally five months after ryzen
7000 has launched so this time around
you'll actually have three 3D V cash
chips to choose from and eight core a 12
core and a 16 core model that's the one
that we're reviewing today but very very
important that 12 core and 16 core model
don't actually get additional 3D cache
over the 7800 X 3D it's not like the
more cores you buy the more stacked V
cash you get although that would be
pretty cool instead all three of these
models here only have one of the two
ccds with that extra 64 megabytes of L3
cache so I think we've all agree it's
the 7800x3d which is looking like the
better option out of the three it's the
cheapest for starters and you're kind of
getting the most 3D enhancement for the
money and also because with amd's latest
chipset driver you're only going to be
gaming with the fastest 8 cores anyway
so even if you buy the 12 or 16 core
model those extra four to eight cores
will literally be asleep when you're
running a game in fact I found the
current public driver to already be
doing this with the non 3D 7950x so look
we are kicking things off with the 16
core 7950x3d today but just keep that in
mind the new chipset driver disables the
non-3dv cache CCD whenever it's under
gaming loads as for the test bench I've
tested all CPUs alongside an RTX 4090
more specifically the liquid-cooled
Supreme Ax from MSI for ddr4 CPUs I've
used 3600 cr16 and for ddr5 parts
including Intel 12th and 13th gen I've
used 6000 megahertz cr36 so let's kick
things off with some competitive Games
first these are usually the games where
you'll see the most CPU scaling and for
these ones I've also included the
average latency on the left there as
well so PC latency you can think of that
as the processing latency of the CPU GPU
and the game combined but this doesn't
include the latency of your mouse or
your monitor it's purely how fast your
system can prepare and finish rendering
a frame effectively you can think of the
right side of this graph showing the
smoothness of the game and the left side
showing the responsiveness so here in
OverWatch 2 yeah we do see the new ryzen
7950x3d right at the top of the chart
however it is by a very slim margin a
good chunk of these CPUs are running
into that 600 FPS cap despite running
these benchmarks at 1440p versus the
5800x3d inputs are one millisecond
faster on average and one percent lose
aramir 7 FPS ahead so barely again here
at all if though you're upgrading from a
ryzen 2000 or 3000 CPU then you will
definitely see a difference five
millisecond faster input and roughly a
double in frame rate however that's also
what you'd see if you were to upgrade to
the 5800x3d in Modern Warfare 2 using
the built-in Benchmark I actually found
the 5800x3d to be slightly faster on
average compared to the new
7950x3d this is also something that I
went back and retested but I kept
getting the same result very interesting
to see for sure and one more reason to
hang on to that 5800x3d if you currently
have one as for f122 despite running
1440p High settings here the GPU usage
for our RTX 4090 was only 83 when paired
with the new 7950x 3D so there is still
some CPU bottlenecking at play having
said that everything from the 5800x3d
and upwards basically shows the same
experience between the old and the new
stuff there's about a 3.5 Improvement on
average and PC latency is basically
identical maybe if we ran this at 1080p
medium to low settings we'd see some
more aggressive scaling here but not
even the best Sim races in the world
play with those
in valorant the 7950x3d finally cracks
that 1000 fps mark on our spike plant
simulation with one percent lose over
600 FPS again though experience wise
there's basically no difference here
versus the 5800 X 3D especially when the
difference in latency is just half a
millisecond but for what it's worth the
7950x3d is the faster chip now keep in
mind if you're playing an actual 5v5
match you'll see frame rates far below
this but the scaling for each CPU should
be about the same we also see
surprisingly good scaling in cyberpunk
2077. here the new 3D chip was five
percent faster on average versus the
non-3d part and 13 faster when it came
to the one percent lows at this point as
well the new 7950x3d almost relieves all
CPU bottlenecking with these settings
GPU usage for r4090 was 95 on average
versus around 92 percent for the 5800 X
3D now there are some instances where
Intel's 13900k ends up on top of
everything in Red Dead Redemption 2 for
example I found the 5800 3D and 17950x3d
to be virtually identical but then the
3900k ends up at 5 faster than both on
average similar story in Doom Eternal 3
900k out on top with the new and old 3D
V cash chips basically pushing the same
performance so there are some instances
just as we saw with the 5800x3d with
that extra L3 cache doesn't really help
a lot then in Rainbow Six even less
convincing gains here the margin between
the top five are incredibly slim but
maybe the biggest difference here out of
all of these CPUs is power consumption
and surprisingly the 7950x3d doesn't
pull that much power at all in valorent
just 76 watts and that's also while
pushing out 1000 fps now apart from the
additional L3 cache there are a few
other differences here over the standard
7950x the default temperature target has
been lowered from 95 to 89 degrees C and
I will mention it hits that really
really easily despite using a 360mm
cooler at 2000 RPM on an open bench the
7950x3d hit 89 degrees within just a
couple of seconds of running cinebench
and it did that while not even pulling
160 Watts so the heat management for
this processor looks a little bit funky
if I'm honest those kind of numbers with
a 360 mil cooler just don't really add
up in particular the CCD with the 3D V
cash stacked on top was warming up
extremely easy and at least in this
scenario around about 20 degrees hotter
than the CCD that doesn't have that
extra cash so something is quite odd
here especially compared to the regular
7950x which has pretty even temperatures
across both ccds so more even heat
distribution within the chip a higher
temperature Target as a result the 7950x
can sustain higher clock speeds and
performance while under these all-core
workloads so if you're looking for the
most multi-threaded performance possible
and you're really serious about
productivity and faster processing times
the standard 7950x is the slightly
faster chip in cinebench it was around
nine percent faster than the new 3D chip
which might hint of why AMD price to
both products the same single threaded
performance on the other hand is about
equal since that heat and power
management doesn't really come into play
here 3d motion tracking is a great
example of that this task only runs on a
single thread oddly here though I still
found the regular chip to be a tiny bit
faster and then in Adobe Media encoder
generating proxy files here for video
editing the 7950x 3D sits right
alongside the 3900k and 7950x as you
would expect so for the most part we are
getting that unreal 16 core ryzen 7000
performance it's only the full ball
rendering and encoding stuff that seems
to take about a five to ten percent
penalty versus the non-3d chip that chip
can boost a little bit higher and get a
little bit warmer so do expect more
performance alright so the 7800 x3d is
probably the one that you want to be
waiting for here to be honest the 17950x
3D it's a bit of a weird CPU like I
guess if you want the gaming benefits
that the 3D V cache provides but you
also want 16 cores I guess that's what
this is trying to serve but at the same
time you know the gains that we're
seeing honestly from the 3D V cache this
time around don't seem that impressive
as what we saw with the 5800x 3D and in
most cases the 5800x3d is still there to
play like if you're currently are on the
am4 platform and you're looking for an
upgrade that chip is just an easy easy
pick it's currently around 330 dollars
you know just update your bios and drop
it in your system and there's no need to
additionally purchase a new am5
motherboard along with ddr5 so I am
looking forward to seeing what that 8
core variant can deliver especially
because these 3D chips are unlocked this
time around so potentially you could
tweak them to the same clock speeds as
what we have here or maybe even faster
now one CPU that I didn't have in the
chance for this one is the 13600k for
what it's worth the gaming performance
there is extremely similar to the 13900k
and if you are looking to build
something from the ground up that's
focused around gaming that and the
5800x3d are currently the two that I'd
still be sticking with but yeah that's
pretty much it as always a huge thanks
for watching and I'll see you all in the
next one
