yeah yeah nanometers aren't an accurate measure of anything i know
but this process is old and this has huge performance implications which will
test on the core i9 11900k and core i5
11600k that we have here today to do that we've grabbed the equivalent 10th
gen core processors along with the ryzen 5 5600x and ryzen 9 5900x for comparison
with team red special note we're running both benches at one-to-one memory more
on that later and we're running these tests under completely stock turbo
limits shadow of the tomb raider is the core i9's first l at a roughly eight
percent lower average FPS than ryzen 9 while the core i5 sees significantly
better minimum frame rates than ryzen 5. gta 5 has the core i9 pulling ahead of
the 5900x by 5 or more in minimum frames
while the core i5 again pulls off a 13 or so lead over ryzen 5's minimums f1
2020's absurd frame rates reveal the generational improvements Intel's
managed here for the core i5 the core i9
appears roughly in line with 10th gen thanks to fewer threads and lower base
clocks fort surprise and 4 has Intel trading blows with AMD with better
minimums and worse averages on both new cpus while turn times in civilization 6
are about half a second or so faster on 11th gen flight sim 2020 has both cpus
ahead of last gen but falling short of AMD and all but the minimum frame rates
cs go is another bloodbath where AMD's zen 3 architecture firmly curb stomps
rocket lake perhaps thanks to the gigantic amount of shared cash ryzen
enjoys although it's worth pointing out that every CPU here is already in
overkill territory moving on to productivity Intel's single threaded
cinebench scores are much better than last gen and higher than amds but not by
a huge amount while puget bench for creative cloud shows that even lightly
threaded workloads like photoshop can still favor AMD again likely thanks to
the extra cash it's not a big l though that comes from blender the core i5
falls behind by 10 in gooseberry while the core i9 because of stock turbo is a
staggering 40 percent slower than ryzen
in the same test corona benchmark being much shorter puts the core i5 much
closer to ryzen 5 and the same goes for v-ray a test that only lasts about a
minute pov ray has Intel very close to AMD and single threaded performance
while the core i9 continues to struggle spec's workstation is mostly another
pain point for Intel but some tests again favoring the 10th gen core i9
thanks to its additional cores and threads even the core i5 struggles with
10 to 14 lower aggregate scores than AMD across the life sciences financial
services and energy segments of the test not looking great so far at least not
for the core i9 but now we need to talk about power and thermals and we're going
to talk a lot because if you recall comet lake was better than coffee lake
for thermals but only because Intel busted out all the tricks of the trade
to make it happen and now despite having two fewer cores all early reports had
rocket lake pegged at basically being a flamethrower in addition to the
performance concerns relative to AMD at stock both our core i9 and core i5
manage thermals that are reasonable thanks in large part to strictly
conforming to Intel's rated 125 watt TDP
once turbo expires they do draw much higher power than last gen to hit their
peak all-core turbo speeds but in the core i9s case Intel's new adaptive boost
technology impressively allows the cores to run 300 megahertz higher all core
than it's rated for this new behavior is similar to AMD's precision boost 2
opportunistically increasing all core clocks within thermal and power limits
but Intel's is still constrained by their finite turbo period of 56 seconds
by default upon disabling this turbo limit using our motherboard's multi-core
enhancement feature the core i9 draws a staggering 275 watts peak with 260 watts
sustained from the socket that is nearly double the ryzen 9's power draw and
around 40 percent more than 10th gens we did get about a 19 faster render time
than stock but even with our Noctua nhd15s the i9 instantly hits 80 degrees
and creeps up to the mid-90s throughout the run bizarrely though the core i5
manages better thermals and power draw with multi-core enhancement compared to
its own stock turbo thanks to a lower core voltage provided by the motherboard
these results however were for avx-2 Intel added the avx-512 instruction set
and machine learning extensions to rocket lake and they're leaning heavily
on them in marketing we don't have any benchmarks for that right now but we can
do a quick stress test with prime95 where at stock we've got ok thermals
again for our core i9 but our core i5 hits the 100 degree mark thanks to a
higher turbo speed before settling into the mid 60s and 70s power consumption
roughly matches the non-avx-512 testing and unsurprisingly both cpus dropped
straight to base clock after the turbo window expired it's when we removed the
limits again that no no Intel
are you okay the core i9 can draw over 290 watts at peak the core i5 once again
draws less power thanks to the motherboard svid control but both cpus
still run toasty enough that our dual tower cooler can just barely handle it
we are really at the limits of what Intel's reheated 14 nanometer process
can do here thankfully you won't have to reheat your drink for up to 8 hours with
a water bottle from ltdstore.com but even without avx-512 you have to ask
why is 11th gen so hot with fewer cores
than last gen aside from abx-512 taking
up a huge amount of die space it was originally built for 10 nanometers
that's right Intel had to back port this thing and that's why we got this really
strange looking product stack no fewer than 10 eight core cpus across core i7
and core i9 nine six core cpus in the core i5 line and everything else is just
a comet like refresh no rocket like core i3s or pentiums this time around without
being able to rely on core counts to cleanly distinguish between skus the
differences are so minor in practice that they're going to make most people
think twice about spending an extra 140 dollars for a core i9 when a core i7 is
almost as good or when AMD is a better performer for the money granted core i9s
get thermal velocity boost and adaptive boost technology but you can mimic that
by enabling multi-core enhancement if your motherboard has it or by maxing out
the power limits manually in Intel xtu if it doesn't all 11th gen core desktop
cpus that we know about have the same cache per core and the same improved
graphics core with expanded video decode capabilities on skus that include them
what's more they all have an extra 4 pci express gen 4 lanes on the CPU now for
NVMe storage like AMD does it gets subscribed by the way because even
within the same model not all NVMe ssds are created equal and we're calling out
the worst offender now there is the issue of gear one mode support tldr it's
just like running infinity fabric in one to one mode with memory speed on ryzen
for better performance the cry9 11900k
and kf are supposed to be the only ones that handle ddr4 3200 memory this way
but from our testing the core i5 11600k can too it's just not the default and
it'll go even higher than that it looks like the core i9's main draw will be in
pre-built pcs that don't expose these options if the core i7 11700k is as
gamer's next has put it a waste of sand
the whole core i9 lineup on paper is even worse
especially the k-sku that's just priced 10 less than ryzen 9. thankfully you
don't need to buy a high-end motherboard to use faster memory now so that's one
savings that's no longer exclusive to team red but that doesn't save the core
i9 in games matching ryzen's performance
is a best case scenario where even the ryzen 5 at times comes close granted it
may not make or break your gameplay but the value is just not there for work
unless you can use avx-512 the extra oomph from ryzen 9's 12 cores means
Intel is not going to be your first choice this generation in that domain
either the real star of the show is the core i5 it's only about two to six
percent slower than the ryzen 5 at stock across our testing but it costs thirty
dollars less at retail even better for Intel availability troubles means the
eleven six hundred k is a hundred dollars cheaper than ryzen 5 street
price making it a no-brainer as long as Intel has the chips to sell bonus if you
don't overclock you'll lose very little by getting a cheaper non-case skew and
turning on multi-core enhancement to offset the difference in base clock just
make sure you get a cooler that can handle it if you're worried about
upgradability ddr5's impending arrival means both teams sockets have an
expiration date at this point so you lose nothing either way if you need a
new CPU today or you lose everything depending on how
you think about it you know glass half empty half full it might be rough going for Intel for a
while longer but it looks like things are improving a week ago their ceo pat
gelsinger announced a renewed focus on fabrication and process technology
including a seven nanometer tile process that will hopefully power meteor lake to
generations from now we've heard this kind of promise from Intel before so
time will tell for now just buy a core i5
