EVENIFIT’Snot the most powerful CPU in
AMD’s newest, third-generationRyzen series,
the Ryzen 73700X makes the best poster
child forwhat this processorfamily is all
about. TheRyzen 93900X (Shopper381) has
more cores and threads, while theRyzen 5
3600 is cheaper,but it’s theRyzen 73700X
that most fully encapsulates the AMD way:
loads of cores, high performance andalow
price,atl east comparedto Intel equivalents.


SWEET 16
First, let’s look at the cores.Youget
eight of them here,with atotal of 16
usable threads via Simultaneous
Multi-Threading (SMT). The
12-core,24-threadRyzen 9
3900X has it beat, but that’s
more forbridging the gap
between mainstream and enthusiast
CPUs; theRyzen 73700X isafully
mainstream chip,and in this arena
it’s unbeatable.Even its closest
Intel rival, the Core i7-9700K, has
eight cores but only eight threads.
Next, performance.Following on
from theRyzen 72700X (Shopper366),
AMD has taken the unusual stepof clocking
the Ryzen 73700X withalower base clock
speed butahigher boost clock speed,
rather than raising both, as you’d expect.
It consequently runs ataminimumof 3.6GHz,
comparedto 3.7GHz on its predecessor,while
its maximum boost clock has gone 100MHz in
the other direction, upto 4.4GHz.
AMD’s usual dynamic auto-overclocking
features, ExtendedFrequency Range (XFR)
and Precision Boost, are both present, but
as with second-generationRyzens, their
potential gains are included in the stated
maximum boost speed.You’ll therefore
need agood coolerto ensure there’s
sufficient cooling headroomforboth
systemsto kick in.
Lowering the base speed also seems
counterproductive,but based on what we’ve
seen from theRyzen 93900X andRyzen 5
3600X, there are reasonsto be confident.
Like these chips, theRyzen 73700X is built


with an updated 7nm FinFET process, making
it moreefficient than previous 12nm and
14nm Ryzens. Thisefficiency doesn’t just
reduce energy consumption; it also allows, in
theory,for more instructions per clock cycle,
potentially allowing the CPUto blast through
more processes at 3.6GHz than theRyzen 7
2700X could at 3.7GHz.
Lastly,there’s the price.We’ve found the
Ryzen 73700X for£313, which is higher than
what theRyzen 72700X cost at launch but
still easily undercuts the £375 Core i7-9700K
–which, don’tforget, offers fewer threads in


exchange.It’s alsoahefty£233 cheaper than
the Ryzen 93900X, which is aneffective
consolationto missing out onfour extra
cores and eight extra threads.

CORE STRENGTH
There’s no integrated graphics, which is fine
as the Ryzen 73700X is intended specifically
fordesktop systems with dedicated graphics
cards. What you do get is an RGB-litWraith
Spire cooler bundled in the box. It’s notabad
start if you spent the lastof your PC build

budget on the chip itself,althoughforthe
best XFR and Precision Boost performance,
it’s betterto pair this CPU with either a
larger air cooler orawatercooler system.
Forconsistency with previousRyzen testing,
we used the Noctua NH-U12S.
With both components installed in our
test PC, withaGTX 1060 on video output
duties, theRyzen 73700X put in a
commanding performance in our benchmark
tests. Its imagetest scoreof 182, for
example,isn’t justamajor improvement on
the Ryzen 72700X’s scoreof 149 –ite ven

beat theRyzen 93900X, which hit 168.
Amazingly,ite ven edges past the 173 scored
by Core i9-9900K, which is supposedto be
Intel’s best single-core performer–even more
so than the Core i7-9700K.
Moving onto the video-encodingtest, the
Ryzen 93900K’s additional threads helped it
take ahealthy lead, but theRyzen 73700X is
still kingof its price range with 315. That’s
practically enoughforprofessional-grade
media editing, contained withinarelatively
affordable consumer CPU.

ONTHE RISE


The multitaskingtest produced its single
best performance,with ascore of 389.
Again, this isn’t close enoughto bother the
Ryzen 93900X, which smashed the record
with 523, but it’s better than you’d get
from even an overclocked Core i7-9700K.
It’s alsoasingle point behind the Core
i9-9900K’s multitaskingtest result: an
incredible achievement, considering Intel’s
top-end chip hasfarhigher clock speeds and
aprice on apar with the 3900X.
Overall, theRyzen 73700X scored an
excellent 330, improving on theRyzen 7
2700X by 99 points and outperforming the
Core i7-9700K. 330 also happensto be the
exact sameoverall score as thatof the Core
i9-9900K, so not only does theRyzen 9
3900X outshine Intel’s premier CPU on
