00:00:53.039 --> 00:01:00.320
yeah yeah nanometers aren't an accurate measure of anything i know

00:00:57.360 --> 00:01:05.600
but this process is old and this has huge performance implications which will

00:01:02.239 --> 00:01:08.400
test on the core i9 11900k and core i5

00:01:05.600 --> 00:01:12.400
11600k that we have here today to do that we've grabbed the equivalent 10th

00:01:10.159 --> 00:01:18.159
gen core processors along with the ryzen 5 5600x and ryzen 9 5900x for comparison

00:01:15.760 --> 00:01:22.320
with team red special note we're running both benches at one-to-one memory more

00:01:20.400 --> 00:01:25.840
on that later and we're running these tests under completely stock turbo

00:01:24.000 --> 00:01:30.799
limits shadow of the tomb raider is the core i9's first l at a roughly eight

00:01:28.000 --> 00:01:35.040
percent lower average FPS than ryzen 9 while the core i5 sees significantly

00:01:32.640 --> 00:01:40.400
better minimum frame rates than ryzen 5. gta 5 has the core i9 pulling ahead of

00:01:37.200 --> 00:01:42.720
the 5900x by 5 or more in minimum frames

00:01:40.400 --> 00:01:48.159
while the core i5 again pulls off a 13 or so lead over ryzen 5's minimums f1

00:01:45.600 --> 00:01:52.720
2020's absurd frame rates reveal the generational improvements Intel's

00:01:49.680 --> 00:01:54.640
managed here for the core i5 the core i9

00:01:52.720 --> 00:01:59.759
appears roughly in line with 10th gen thanks to fewer threads and lower base

00:01:56.799 --> 00:02:03.439
clocks fort surprise and 4 has Intel trading blows with AMD with better

00:02:01.439 --> 00:02:08.560
minimums and worse averages on both new cpus while turn times in civilization 6

00:02:06.320 --> 00:02:13.760
are about half a second or so faster on 11th gen flight sim 2020 has both cpus

00:02:11.680 --> 00:02:18.720
ahead of last gen but falling short of AMD and all but the minimum frame rates

00:02:16.480 --> 00:02:22.400
cs go is another bloodbath where AMD's zen 3 architecture firmly curb stomps

00:02:20.800 --> 00:02:26.319
rocket lake perhaps thanks to the gigantic amount of shared cash ryzen

00:02:24.480 --> 00:02:30.319
enjoys although it's worth pointing out that every CPU here is already in

00:02:28.319 --> 00:02:33.920
overkill territory moving on to productivity Intel's single threaded

00:02:32.319 --> 00:02:38.879
cinebench scores are much better than last gen and higher than amds but not by

00:02:36.800 --> 00:02:42.480
a huge amount while puget bench for creative cloud shows that even lightly

00:02:40.640 --> 00:02:47.599
threaded workloads like photoshop can still favor AMD again likely thanks to

00:02:45.040 --> 00:02:52.319
the extra cash it's not a big l though that comes from blender the core i5

00:02:49.920 --> 00:02:57.760
falls behind by 10 in gooseberry while the core i9 because of stock turbo is a

00:02:54.640 --> 00:03:00.640
staggering 40 percent slower than ryzen

00:02:57.760 --> 00:03:04.879
in the same test corona benchmark being much shorter puts the core i5 much

00:03:02.720 --> 00:03:09.680
closer to ryzen 5 and the same goes for v-ray a test that only lasts about a

00:03:06.959 --> 00:03:13.360
minute pov ray has Intel very close to AMD and single threaded performance

00:03:11.120 --> 00:03:17.360
while the core i9 continues to struggle spec's workstation is mostly another

00:03:15.360 --> 00:03:20.959
pain point for Intel but some tests again favoring the 10th gen core i9

00:03:19.680 --> 00:03:26.000
thanks to its additional cores and threads even the core i5 struggles with

00:03:23.360 --> 00:03:30.480
10 to 14 lower aggregate scores than AMD across the life sciences financial

00:03:27.920 --> 00:03:34.239
services and energy segments of the test not looking great so far at least not

00:03:32.400 --> 00:03:38.480
for the core i9 but now we need to talk about power and thermals and we're going

00:03:36.400 --> 00:03:41.920
to talk a lot because if you recall comet lake was better than coffee lake

00:03:40.080 --> 00:03:45.760
for thermals but only because Intel busted out all the tricks of the trade

00:03:43.440 --> 00:03:50.400
to make it happen and now despite having two fewer cores all early reports had

00:03:48.159 --> 00:03:54.159
rocket lake pegged at basically being a flamethrower in addition to the

00:03:51.760 --> 00:03:58.640
performance concerns relative to AMD at stock both our core i9 and core i5

00:03:56.720 --> 00:04:03.920
manage thermals that are reasonable thanks in large part to strictly

00:04:00.000 --> 00:04:06.319
conforming to Intel's rated 125 watt TDP

00:04:03.920 --> 00:04:09.840
once turbo expires they do draw much higher power than last gen to hit their

00:04:07.920 --> 00:04:14.000
peak all-core turbo speeds but in the core i9s case Intel's new adaptive boost

00:04:12.159 --> 00:04:18.160
technology impressively allows the cores to run 300 megahertz higher all core

00:04:15.920 --> 00:04:22.079
than it's rated for this new behavior is similar to AMD's precision boost 2

00:04:20.160 --> 00:04:26.000
opportunistically increasing all core clocks within thermal and power limits

00:04:23.919 --> 00:04:30.639
but Intel's is still constrained by their finite turbo period of 56 seconds

00:04:28.160 --> 00:04:35.280
by default upon disabling this turbo limit using our motherboard's multi-core

00:04:32.400 --> 00:04:42.240
enhancement feature the core i9 draws a staggering 275 watts peak with 260 watts

00:04:39.600 --> 00:04:47.280
sustained from the socket that is nearly double the ryzen 9's power draw and

00:04:44.320 --> 00:04:52.160
around 40 percent more than 10th gens we did get about a 19 faster render time

00:04:49.919 --> 00:04:57.520
than stock but even with our Noctua nhd15s the i9 instantly hits 80 degrees

00:04:55.759 --> 00:05:01.919
and creeps up to the mid-90s throughout the run bizarrely though the core i5

00:04:59.759 --> 00:05:05.840
manages better thermals and power draw with multi-core enhancement compared to

00:05:03.280 --> 00:05:10.479
its own stock turbo thanks to a lower core voltage provided by the motherboard

00:05:07.680 --> 00:05:14.240
these results however were for avx-2 Intel added the avx-512 instruction set

00:05:12.880 --> 00:05:18.160
and machine learning extensions to rocket lake and they're leaning heavily

00:05:16.479 --> 00:05:22.000
on them in marketing we don't have any benchmarks for that right now but we can

00:05:20.080 --> 00:05:26.639
do a quick stress test with prime95 where at stock we've got ok thermals

00:05:24.400 --> 00:05:30.240
again for our core i9 but our core i5 hits the 100 degree mark thanks to a

00:05:28.080 --> 00:05:35.520
higher turbo speed before settling into the mid 60s and 70s power consumption

00:05:32.800 --> 00:05:39.199
roughly matches the non-avx-512 testing and unsurprisingly both cpus dropped

00:05:37.600 --> 00:05:44.160
straight to base clock after the turbo window expired it's when we removed the

00:05:41.280 --> 00:05:47.840
limits again that no no Intel

00:05:45.120 --> 00:05:52.400
are you okay the core i9 can draw over 290 watts at peak the core i5 once again

00:05:51.120 --> 00:05:57.199
draws less power thanks to the motherboard svid control but both cpus

00:05:55.280 --> 00:06:01.280
still run toasty enough that our dual tower cooler can just barely handle it

00:05:59.440 --> 00:06:05.759
we are really at the limits of what Intel's reheated 14 nanometer process

00:06:03.360 --> 00:06:09.520
can do here thankfully you won't have to reheat your drink for up to 8 hours with

00:06:07.280 --> 00:06:16.880
a water bottle from ltdstore.com but even without avx-512 you have to ask

00:06:13.039 --> 00:06:19.919
why is 11th gen so hot with fewer cores

00:06:16.880 --> 00:06:22.240
than last gen aside from abx-512 taking

00:06:19.919 --> 00:06:27.039
up a huge amount of die space it was originally built for 10 nanometers

00:06:24.800 --> 00:06:31.440
that's right Intel had to back port this thing and that's why we got this really

00:06:29.120 --> 00:06:36.800
strange looking product stack no fewer than 10 eight core cpus across core i7

00:06:34.000 --> 00:06:42.000
and core i9 nine six core cpus in the core i5 line and everything else is just

00:06:39.440 --> 00:06:46.080
a comet like refresh no rocket like core i3s or pentiums this time around without

00:06:44.319 --> 00:06:50.639
being able to rely on core counts to cleanly distinguish between skus the

00:06:48.319 --> 00:06:54.160
differences are so minor in practice that they're going to make most people

00:06:52.000 --> 00:06:59.440
think twice about spending an extra 140 dollars for a core i9 when a core i7 is

00:06:56.960 --> 00:07:03.759
almost as good or when AMD is a better performer for the money granted core i9s

00:07:01.919 --> 00:07:07.599
get thermal velocity boost and adaptive boost technology but you can mimic that

00:07:05.919 --> 00:07:11.520
by enabling multi-core enhancement if your motherboard has it or by maxing out

00:07:09.520 --> 00:07:16.160
the power limits manually in Intel xtu if it doesn't all 11th gen core desktop

00:07:14.000 --> 00:07:20.080
cpus that we know about have the same cache per core and the same improved

00:07:18.160 --> 00:07:24.960
graphics core with expanded video decode capabilities on skus that include them

00:07:22.160 --> 00:07:29.680
what's more they all have an extra 4 pci express gen 4 lanes on the CPU now for

00:07:27.280 --> 00:07:33.360
NVMe storage like AMD does it gets subscribed by the way because even

00:07:31.039 --> 00:07:37.039
within the same model not all NVMe ssds are created equal and we're calling out

00:07:34.960 --> 00:07:42.240
the worst offender now there is the issue of gear one mode support tldr it's

00:07:40.479 --> 00:07:47.039
just like running infinity fabric in one to one mode with memory speed on ryzen

00:07:44.000 --> 00:07:48.880
for better performance the cry9 11900k

00:07:47.039 --> 00:07:54.400
and kf are supposed to be the only ones that handle ddr4 3200 memory this way

00:07:51.680 --> 00:07:59.120
but from our testing the core i5 11600k can too it's just not the default and

00:07:57.120 --> 00:08:03.360
it'll go even higher than that it looks like the core i9's main draw will be in

00:08:01.440 --> 00:08:10.400
pre-built pcs that don't expose these options if the core i7 11700k is as

00:08:07.280 --> 00:08:12.400
gamer's next has put it a waste of sand

00:08:10.400 --> 00:08:17.199
the whole core i9 lineup on paper is even worse

00:08:14.720 --> 00:08:21.440
especially the k-sku that's just priced 10 less than ryzen 9. thankfully you

00:08:19.919 --> 00:08:25.039
don't need to buy a high-end motherboard to use faster memory now so that's one

00:08:23.440 --> 00:08:30.639
savings that's no longer exclusive to team red but that doesn't save the core

00:08:26.879 --> 00:08:32.719
i9 in games matching ryzen's performance

00:08:30.639 --> 00:08:38.240
is a best case scenario where even the ryzen 5 at times comes close granted it

00:08:35.760 --> 00:08:43.599
may not make or break your gameplay but the value is just not there for work

00:08:40.719 --> 00:08:48.399
unless you can use avx-512 the extra oomph from ryzen 9's 12 cores means

00:08:46.320 --> 00:08:52.560
Intel is not going to be your first choice this generation in that domain

00:08:50.240 --> 00:08:57.200
either the real star of the show is the core i5 it's only about two to six

00:08:55.279 --> 00:09:01.760
percent slower than the ryzen 5 at stock across our testing but it costs thirty

00:08:59.519 --> 00:09:05.600
dollars less at retail even better for Intel availability troubles means the

00:09:03.760 --> 00:09:09.279
eleven six hundred k is a hundred dollars cheaper than ryzen 5 street

00:09:07.200 --> 00:09:13.440
price making it a no-brainer as long as Intel has the chips to sell bonus if you

00:09:11.680 --> 00:09:16.720
don't overclock you'll lose very little by getting a cheaper non-case skew and

00:09:15.360 --> 00:09:19.680
turning on multi-core enhancement to offset the difference in base clock just

00:09:18.560 --> 00:09:24.080
make sure you get a cooler that can handle it if you're worried about

00:09:21.600 --> 00:09:27.600
upgradability ddr5's impending arrival means both teams sockets have an

00:09:25.920 --> 00:09:30.560
expiration date at this point so you lose nothing either way if you need a

00:09:29.040 --> 00:09:33.839
new CPU today or you lose everything depending on how

00:09:32.480 --> 00:09:39.360
you think about it you know glass half empty half full it might be rough going for Intel for a

00:09:37.200 --> 00:09:44.640
while longer but it looks like things are improving a week ago their ceo pat

00:09:41.920 --> 00:09:48.720
gelsinger announced a renewed focus on fabrication and process technology

00:09:46.399 --> 00:09:52.800
including a seven nanometer tile process that will hopefully power meteor lake to

00:09:50.959 --> 00:09:58.560
generations from now we've heard this kind of promise from Intel before so

00:09:56.080 --> 00:10:03.279
time will tell for now just buy a core i5

00:10:00.320 --> 00:10:07.279
