00:00:00.000 --> 00:00:08.160
hello guys CPUs are hot and use too much power

00:00:04.580 --> 00:00:12.240
but who is right in this sephorus G14 we

00:00:08.160 --> 00:00:16.020
have AMD ryzen 9 6900 HS nice and over

00:00:12.240 --> 00:00:18.180
here at Intel I9 12900 HK we already saw

00:00:16.020 --> 00:00:24.180
the Intel's 12th gen was a massive step forward but AMD claims they have a 2.62

00:00:21.480 --> 00:00:29.160
times jump in performance per watt so can ryzen 6000 reclaim the mobile CPU

00:00:27.060 --> 00:00:34.380
Throne we'll give you the numbers after the segue to our sponsor Corsair

00:00:31.019 --> 00:00:36.480
Corsair's new IQ 5000 T case offers a

00:00:34.380 --> 00:00:41.219
unique design 208 individually addressable RGB LEDs and tons of Builder

00:00:39.300 --> 00:00:43.520
friendly features learn more at the link below

00:00:47.059 --> 00:00:50.120
all right

00:00:50.539 --> 00:00:57.180
AMD's ryzen 9 6900 HS is an 8 core 16

00:00:54.600 --> 00:01:01.980
thread CPU that according to AMD has been optimized from the ground up for

00:00:59.579 --> 00:01:07.260
exceptional performance per watt unlike the upcoming desktop CPUs that will be

00:01:04.080 --> 00:01:09.960
using Zen 4 ryzen 6000 mobile uses Zen 3

00:01:07.260 --> 00:01:14.340
plus Rembrandt architecture these chips are manufactured using tsmc's six

00:01:12.060 --> 00:01:19.439
nanometer process and earned them five slides of just how darn efficient they

00:01:16.560 --> 00:01:23.520
are but how do AMD's claims transfer to the real world well the first thing I

00:01:21.720 --> 00:01:30.479
did with these two laptops is run cinebench R23 and the results blew me

00:01:26.880 --> 00:01:33.840
away the AMD ryzen 9 6900 HS came

00:01:30.479 --> 00:01:36.240
shockingly close to the I9 12900 HK and

00:01:33.840 --> 00:01:42.180
I say shocking because AMD's chip has a TDP of 45 Watts

00:01:38.820 --> 00:01:44.040
and it tells us 110. AMD has been making

00:01:42.180 --> 00:01:48.840
a huge deal about the performance per watt of these chips and then this might

00:01:45.780 --> 00:01:50.640
be um no no never mind reviewing the

00:01:48.840 --> 00:01:55.320
hardware info logs show that the Intel chip briefly Drew 110 watts and then

00:01:53.220 --> 00:02:01.439
quickly settled around 80. whereas the AMD chip boosted to 80 watts and then

00:01:58.320 --> 00:02:03.000
settled around 75 meaning Intel might be

00:02:01.439 --> 00:02:07.920
onto something with their mixture of performance and efficiency cores in

00:02:05.219 --> 00:02:12.540
laptops the TD specs you see are largely meaningless the CPU will use however

00:02:10.500 --> 00:02:17.040
much power is available until either the cooler or the vrms can't take it anymore

00:02:14.640 --> 00:02:21.959
and good thing techtubers exist because there's basically no way to know what a

00:02:19.440 --> 00:02:25.379
laptop CPU will do until someone goes out and tests it since in laptops

00:02:23.940 --> 00:02:30.000
whoever can get the best performance while using the smallest amount of power

00:02:27.180 --> 00:02:34.800
wins I devise a little test using the ASUS Armory crate on AMD and throttle

00:02:32.520 --> 00:02:39.780
stop on Intel I was able to equalize the tdps of the CPUs then I ran the blender

00:02:37.379 --> 00:02:44.040
BMW test to see how while they performed this way we can start at 70 watts and

00:02:42.239 --> 00:02:48.840
end at 20 to see which CPU will work best over the largest number of laptops

00:02:46.440 --> 00:02:53.760
oh the gate Intel took the lead as expected with wins at 60 and 70 Watts

00:02:51.360 --> 00:02:58.319
but when we got to 50 Watts things started to change here AMD took their

00:02:56.340 --> 00:03:04.379
first win and after that it was just a bloodbath the craziest bit is that

00:03:00.720 --> 00:03:06.480
between 30 and 25 watts Intel's time

00:03:04.379 --> 00:03:11.280
increased by a whole minute that's longer than it takes to order a water

00:03:08.340 --> 00:03:16.200
bottle at lttstore.com I would have liked to go further but a 20 watts AMD

00:03:13.920 --> 00:03:19.860
started disregarding the Armory crate limits and gave the CPU a little bit

00:03:17.879 --> 00:03:24.180
more juice but like at this point we can pretty safely guess Intel is not making

00:03:21.720 --> 00:03:29.640
a comeback I do want to be careful here because it is very possible that Intel

00:03:26.280 --> 00:03:32.459
hasn't tuned the I9 12900 HK to use

00:03:29.640 --> 00:03:37.500
under about 50 watts of power in the future the lower power chips from them

00:03:34.560 --> 00:03:41.280
might be better in this range but looking at their lineup I'm pretty

00:03:39.540 --> 00:03:47.760
confident in my findings 45 Watts Intel will have their P series

00:03:43.980 --> 00:03:50.760
CPUs with six P cores and eight e-cores

00:03:47.760 --> 00:03:53.040
with a turbo Power of 64 Watts but once

00:03:50.760 --> 00:04:00.920
you get to the U Series where the TDP dips below 45 Watts the number of cores

00:03:56.340 --> 00:04:04.620
drops dramatically I 15 watts Intel's i7

00:04:00.920 --> 00:04:07.140
1265u only gets two performance cores

00:04:04.620 --> 00:04:11.879
and I'm very suspicious that they'll be heavily leaning on the 55 watt Turbo

00:04:09.540 --> 00:04:17.280
Power to extract any performance from these CPUs meanwhile over a team red it

00:04:15.060 --> 00:04:22.079
seems like AMD can just take their 8 core 6900hs and limit the power to

00:04:19.859 --> 00:04:25.919
whatever TDP is needed and the performance just scales linearly what

00:04:24.660 --> 00:04:29.940
all this means is that the choice between AMD and intellicode come down to

00:04:28.259 --> 00:04:34.500
the TDP of the laptop that you're looking for Intel has the lead and

00:04:32.100 --> 00:04:39.720
outright performance so if you need a beast of a gaming laptop with a TDP of

00:04:37.020 --> 00:04:45.120
over 45 Watts I lean towards team blue but if you want decent performance and a

00:04:42.660 --> 00:04:51.000
smaller machine I'd deal with AMD below 45 Watts the bit that uh sucks for Intel

00:04:48.600 --> 00:04:56.280
is that I don't know many people looking for desktop Replacements but I know

00:04:53.460 --> 00:05:01.560
loads of people that are looking for a reasonably well performing laptop that's

00:04:58.139 --> 00:05:03.360
you know light and has long battery oh

00:05:01.560 --> 00:05:11.100
and speaking of which the battery life on the 6900 HS is excellent our last gen

00:05:07.080 --> 00:05:13.560
zephyrus G14 with a 5900 HS got us 5

00:05:11.100 --> 00:05:20.340
hours and 42 minutes away from the wall while the new 6900 HS lasted a massive

00:05:17.460 --> 00:05:25.680
11 hours and 11 minutes both have 76 watt hour batteries and 2K

00:05:23.160 --> 00:05:30.000
screens so my only explanation is that AMD weren't lying with that slide deck

00:05:28.080 --> 00:05:34.800
get subscribed because we'll dig more into this in our full review of the ASUS

00:05:32.100 --> 00:05:38.460
zephyrus G14 next week I've only had what

00:05:35.820 --> 00:05:43.020
26 hours with this thing and that is not enough time to upload a video claiming

00:05:40.199 --> 00:05:47.460
is the best Windows laptop in existence which it very well may be what is crazy

00:05:45.720 --> 00:05:53.340
though is that we haven't even talked about what is potentially the biggest

00:05:49.259 --> 00:05:55.380
upgrade in ryzen 6000 rdna2 Graphics aka

00:05:53.340 --> 00:06:00.840
the same Graphics architecture in the PS5 and Xbox series X don't expect to be

00:05:58.560 --> 00:06:06.720
cranking the details in modern games but a 1080p you can play basically

00:06:03.240 --> 00:06:09.660
everything like we managed 85 FPS in

00:06:06.720 --> 00:06:15.539
Forza Horizon 5 on low details the iris XD graphics and the I9 12900 HK only

00:06:13.259 --> 00:06:19.919
managed 46. damn

00:06:17.100 --> 00:06:23.220
this difference is so massive that for thinning lights I don't even know if I

00:06:21.479 --> 00:06:27.539
can recommend an Intel System since you'll have such a better gaming

00:06:24.960 --> 00:06:30.840
experience than AMD honestly I just can't wait to see what kind of cool

00:06:29.220 --> 00:06:34.860
gaming devices will come out in the next couple of years that take advantage of

00:06:32.460 --> 00:06:40.020
our dna2 they've already blown me away with a steam deck and hopefully that's

00:06:36.720 --> 00:06:41.699
only the tip of the iceberg so yeah AMD

00:06:40.020 --> 00:06:45.780
wasn't able to take back the performance Crown from Intel with Rembrandt but

00:06:44.039 --> 00:06:51.479
they've managed to create a much more well-rounded CPU that holds up across

00:06:48.479 --> 00:06:54.300
the TDP range and features the best igpu

00:06:51.479 --> 00:06:57.539
by a mile I can't wait to see what laptops come out using these and I also

00:06:56.220 --> 00:07:01.259
can't wait to tell you about our sponsor Ting thanks to Ting mobile for
