the ryzen 7 7800x3d is the best gaming
CPU on the planet Bar None it isn't even close
I should be celebrating then yeah so why do I look so mad because as far as I can
tell AMD intentionally manipulated the community in the lead-up to this launch
first they pushed their most rabid fans
to more expensive and arguably worse
ryzen 9 x 3D CPUs at launch although
that's nothing new and all the major players have done this at one time or another but the second one is much more
nefarious and reminds me of the way that Intel timed the release of their 10th
gen hddt processors in a way that avoided direct comparisons to AMD's far
superior threadripper 3000 it's yucky and I'm gonna spell out why it's such a
problem shortly first I need to spell out why AMD now makes the only gaming
CPUs that matter and I need to spell out this s-e-g-u-e to our sponsor gizmogo

below it's been almost a year since AMD launched their first processor featuring
3D vcash technology the ryzen 7 5800 X
3D and to say that it's been a game changer would be both an understatement
and a delightfully delicious dad joke the details are complex but the result
is simple 3D vcache allows AMD to stack
up the caches in their processors vertically increasing their capacity
without increasing the die area of the finished chip a larger cache means that
any data the processor needs is more likely to be right at hand rather than
stored in much slower system memory or heaven forbid persistent storage like an
SSD there are trade-offs reading between the lines 3D V cache has some downsides
it appears to be much more sensitive to high voltages which makes overclocking a
less fruitful not to mention riskier Endeavor and has forced AMD to reduce
their out-of-the-box clock speeds it also reduces the rate at which heat can
be dissipated from the course meaning that 3D V cache chips have their thermal
targets reigned in but it seems to be worth it because while AMD's slide deck
has the 7800x 3D competing with the core i7 13700k in terms of pricing if we
consider quite literally anything else it is not even a contest especially in
gaming where it makes such a difference to Performance that well I'll just let
the graphs do the talking here look at
these margins of Victory dang
I mean if you like spending a hundred dollars more for Less performance from
Team blue then that's kind of your prerogative but if you're the sort of
gamer looking to drive the latest 1080p High refresh rate monitors the only
sensible choices we're looking at here are the 5800x 3D on a cheap and cheerful
am4 board with 16 gigs of memory for another 50 bucks or if you've got the
extra cash to put into a newer platform AMD's 7800x 3D absolutely obliterates
everything in its weight class I mean even its own x3d equipped Bigger
Brothers fall considerably behind which raises some big questions like what the
and why Paulo kohilo said that the core of
beauty is Simplicity and I think that applies well here the 7800x 3D comes
equipped with a mere 8 course on a single core complex die or CCD that
means virtually all applications will benefit from its whopping 104 megabytes
of on-die cache and since there's only one CCD there's no latency penalty from
pulling cached data off of another die by contrast the 7900x3d and the 7950x3d
have 12 cores and 16 cores respectively
across two heterogeneous ccds AMD's
rationale for the design Choice does make sense half of the cores get 3D V
cash for killer gaming performance while the other half issue it in favor of
higher yields and higher boost clocks for productivity but in practice getting
applications to run on the most optimal core is a big challenge especially when
you don't bother to build an on-chip Hardware sketch or load balancer and it
results in lower real world performance that puts the ryzen 9x3d chips in this
super weird in-between Zone where they fall behind their lean mean ryzen 7
relative in gaming and then fall behind their own non-x3d counterparts in other
applications of course as we pointed out
in our review of those chips most people aren't buying 500 CPUs or even 350 ones
for that matter to game at 1080P and if the 7800x 3D can't keep its lead going
into 1440p I think oh it does looking at
average frame rates the 7800x3d tops the charts almost without exception only
losing in games where Intel CPUs tend to provide improvements in one percent lows
even games that are clearly GPU Bound in our testing like Modern Warfare 2 and
Red Dead Redemption 2 see the 7800x3d
generally eke out a small W there are
exceptions occasionally even gay won't benefit from 3D V cash and would just
much rather have a CPU that boosts higher but the overall picture is clear
to the point where I'm not sure I remember ever seeing anything quite like
this I mean the thing is for you the viewer watching this 10 FPS here five
percent difference there it might not seem like that big of a deal I don't
even play those games you might say but that isn't the point our test Suite
is designed to guide you toward the product that will provide the best
long-term value not just in games today but in games in the future and that five
percent today can easily turn into eight percent tomorrow or 15 a few years from
now when faster gpus arrive and need more powerful CPUs to perform their best
here's an edge case that illustrates my point very well factorio's unit
simulation update rate is capped in game to 60 per second that means that any one
of our CPUs is going to deliver a peak optimal experience in this game
but by forcing the game's engine to push Beyond these artificial limits we can at
least attempt to draw conclusions about the benefits we might enjoy in future
Sim heavy games if we choose the right Hardware today and the right choice
isn't always obvious from the manufacturer's marketing you might
quickly skim a headline or two and go oh okay 3D V cache is great I'll just get
the best one with that but as you can see when we force factorio to run on the
3D V cache cores by disabling the other ones it performs right neck and neck
with the 7800x 3D but when we leave it at default with all the cores enabled it
falls way back in line with the rest of the pack pretty questionable behavior
for a gaming CPU don't you think and
pretty questionable behavior from AMD when they split up the launch of the
7000 X 3D product line I believed that
they simply wanted to capitalize on early adopters who were willing to pay
for more cores than they needed in order to get the latest shiny 3 3db cash chips
I mean why play an ace if a tool do it's
not an unusual strategy and is absolutely the reason that NVIDIA slow
rolls their product lineups top to bottom over time but the thing NVIDIA
doesn't do is launch a 4090 at Halo tier
pricing only for buyers to end up ticked off when the 4070 arrives a few months
later and is not only cheaper but actually performs better in games and it
wouldn't have bothered me so much if AMD had seated review samples of the chips
at the same time then simply staggered availability like we did with our
screwdriver that is now live shipping on ltdstore.com but by splitting up the launches they
created an environment where users who are seeking a review today of the ryzen
9 x 3D chips are going to find countless articles comparing against Intel 13th
gen but very few comparing against the
cheaper Superior gaming product in AMD's
own lineup now I doubt this strategy will make any kind of material
difference to their sales in spite of Intel jumping a day ahead of AMD's
release 10th gen core I9 was a sales disaster but I just don't like being
played and I feel a little played right now though of course there is the
argument that none of this matters Anyway by the time you get into Ultra HD
gaming which is likely where many of those ryzen 9s are headed we didn't test
as many games at this resolution since there's only so many times you can try
to split the same hair but the bottom line is that the worst we're looking at
across the entire range of chips we tested is about six to seven percent
however that is due to the Mass massive
20 range in F1 2022
if you're the kind of gamer then who prefers High Fidelity experiences over a
Competitive Edge then GPU bound games like cyberpunk and Shadow of the Tomb
Raider you're just not gonna notice a difference and the same is true in our
Ray Trace 4K games where the difference is even smaller I'm still a bit
irritated it is kind of my job because I
could make that exact same well it doesn't really matter anyway argument
about the ryzen 9 x 3D chips as I move
into our productivity results if a few percent FPS here and there
doesn't matter to you in games well then you still should be paying the premium
for these x3d chips because you would still be more than happy gaming on the
regular X variants for cheaper and those
non-3d chips will perform anywhere from about the same as their x3d equivalents
to even better outside of games sorry this has gotten a bit derailed the
video is supposed to be about the 7800x 3D and as you see on all of these charts
it isn't a top performer here but we never expected it to be though it did
Crush another metric that we did expect in our review of the ryzen 9 x 3D chips
we took issue with AMD's marketing they called them gaming CPUs but we felt that
their strength was actually in their efficiency and we are seeing the exact
same thing here except that it is also a
standout gaming value I know that the average gamer doesn't salivate over
better performance per watt but this chip is so exceptional that I gotta slow
you down and talk through this if you game two hours a day in California your
7800 X 3D is going to cost you about 750
a year to run for context AMD's closest
non-x3d the 7700x is gonna cost you more
like 950 and an Intel 13600k about nine
dollars now watch this let's add an hour
a day of video encoding or 3D rendering some other heavy load then let's assume
a five-year lifespan for this system and holy crap the total cost of ownership
goes from a boring metric for data center Architects to a serious
consideration for enthusiasts and Gamers especially if they live in a region
where energy costs are spiraling out of control like in the UK of course though
value over time isn't the only consideration when specing out a new pc
how much is this thing costing me today Linus
less than you'd think at launch amb's am5 platform took a lot of flack for
being poorly positioned compared to Intel's relatively inexpensive LGA 1700
socket they did have the benefit of a supposedly longer support roadmap but
AMD's record on that is imperfect these days at best and the chips the RAM and
the motherboards were very expensive nowadays though the story is quite
different a solid b650 board is going to run you around 200 US dollars 16 gigs of
high-speed ddr5 will set you back under a hundred and the fastest gaming chip on
the Block the 7800x 3D is going to cost you 450 bucks throw in a GPU and some
other bits and Bobs and you're looking at an absolutely killer machine for less
than fifteen hundred dollars still not cheap but if you want to save
a buck the 5800 X 3D is still out there for a hundred dollars less and the
market is flooded with dirt cheap am4 motherboards and ddr4 memory
I wouldn't say then that Intel is down for the count but they do need to
counter hard or it's going to be hard to come up with a reason to build blue that
is at least for now almost as hard as a
