00:00:00.400 --> 00:00:07.600
i think on some level Intel must know that their product

00:00:04.720 --> 00:00:11.200
naming scheme could be less confusing where that level is well your guess is

00:00:09.840 --> 00:00:15.280
as good as mine because they have certainly never admitted it to us

00:00:14.160 --> 00:00:20.960
and yet here we are with an Intel sponsored

00:00:17.760 --> 00:00:23.119
deeper dive into the core x series their

00:00:20.960 --> 00:00:29.410
high-end desktop processors where we'll cover the key options available and what

00:00:26.240 --> 00:00:32.510
they might be most useful for

00:00:35.520 --> 00:00:41.920
okay so first a little context Intel's

00:00:38.559 --> 00:00:45.680
x299 platform is divided up into two

00:00:41.920 --> 00:00:46.879
major architectures kb lake x and sky

00:00:45.680 --> 00:00:52.480
lake x kb lake x is essentially their consumer

00:00:49.680 --> 00:00:57.520
7000 series chips with more heavy duty traces slightly higher clock speeds and

00:00:55.600 --> 00:01:03.760
the higher power consumption that goes with it as a result it differs significantly

00:01:01.199 --> 00:01:08.640
from other cpus that fit into the lga 2066 socket

00:01:05.680 --> 00:01:13.680
Intel intends them as entry-level chips for folks who want to get into an hedt

00:01:10.960 --> 00:01:17.520
or high-end desktop motherboard and then upgrade later but so far they've been

00:01:15.760 --> 00:01:21.920
most successful in competitive overclocking especially in light of the

00:01:20.080 --> 00:01:28.240
six core options that are available on the z370 consumer side of things now

00:01:25.360 --> 00:01:34.880
skylake x on the other hand is where the meat's at here we've got two classes of

00:01:31.119 --> 00:01:37.040
processors core i7 and core i9

00:01:34.880 --> 00:01:40.799
all of them have unlocked multipliers for overclocking

00:01:38.560 --> 00:01:47.759
Intel hyper threading technology quad-channel ddr4 memory support for

00:01:43.360 --> 00:01:50.399
avx-2 and avx-512 x86 extensions and

00:01:47.759 --> 00:01:54.560
they share skylakex's new cache setup of one meg of level two cache per core

00:01:52.479 --> 00:01:58.479
matched with a shared level 3 cache that's much smaller than previous

00:01:56.159 --> 00:02:03.040
generations but in practice proves more efficient in most scenarios

00:02:00.479 --> 00:02:07.200
where they differ is in the core count which increments by 2 for each step up

00:02:05.280 --> 00:02:12.560
the product stack the number of pci express lanes which is lower on core i7

00:02:09.920 --> 00:02:19.599
models and the implementation of turbo boost max 3.0 so cpus with 8 cores or

00:02:16.640 --> 00:02:25.280
more get 2 max boost cores while the 7800x gets zero turbo boost max cores

00:02:23.120 --> 00:02:30.160
now we won't be doing a deep dive on every sku

00:02:26.560 --> 00:02:32.560
just the top-tier core i9 7980xe to show

00:02:30.160 --> 00:02:39.280
what the platform is capable of in multi-threaded and virtualized workloads

00:02:35.120 --> 00:02:41.239
the core i9 7900x the jack of all trades

00:02:39.280 --> 00:02:46.640
and the core i7 7820x which we believe

00:02:43.840 --> 00:02:52.319
should be the entry-level CPU for most buyers on this platform let's start with

00:02:49.360 --> 00:02:57.840
that last one it has 28 pci express lanes so that's enough for a full speed

00:02:54.400 --> 00:03:00.160
graphics card a couple of NVMe ssds and

00:02:57.840 --> 00:03:04.640
some high-speed networking so it's about right for an entry-level workstation

00:03:02.400 --> 00:03:09.040
which is great because that's where this chip's performance shines

00:03:06.959 --> 00:03:14.480
it actually has the highest bass frequency in the entire skylake x lineup

00:03:12.000 --> 00:03:20.959
it shares the highest boost frequency with the 7900x and it also shares the

00:03:18.159 --> 00:03:27.280
highest 2 core turbo boost max 3.0 frequency at 4.5 gigahertz making it a

00:03:24.400 --> 00:03:32.720
great fit for a workstation that isn't always used for work

00:03:29.840 --> 00:03:38.879
moving into core i9 territory we leave behind the 28 PCIe lanes and step up to

00:03:36.159 --> 00:03:45.599
44 where we get perhaps the most interesting CPU in the x299 lineup the

00:03:42.239 --> 00:03:47.599
10 core core i9 7900x

00:03:45.599 --> 00:03:51.280
when this guy launched we reviewed it quite favorably thanks to its major

00:03:49.680 --> 00:03:57.760
performance improvements over its predecessor the core i7

00:03:53.720 --> 00:04:00.400
6900k and even the 6950x

00:03:57.760 --> 00:04:06.319
now to be clear not everyone is going to see a performance improvement versus the

00:04:02.599 --> 00:04:09.280
7820x but if you want to have full

00:04:06.319 --> 00:04:14.959
unbottlenecked access to many connected pci express devices be they networking

00:04:12.159 --> 00:04:20.239
storage video capture or expensive accelerator cards this is where you want

00:04:17.600 --> 00:04:24.400
to be and you get another two cores for workloads that can take advantage of

00:04:22.079 --> 00:04:29.360
them as well the rest of the core i9 lineup is what i would describe as

00:04:26.639 --> 00:04:35.680
tweeners that is they are in between the 7900x two cores per step and the highest

00:04:33.120 --> 00:04:42.960
end CPU Intel has ever released on a desktop platform the 2 000

00:04:38.800 --> 00:04:45.280
18 core core i9 7980

00:04:42.960 --> 00:04:50.639
this thing is an absolute beast and it shows in both its performance numbers

00:04:47.840 --> 00:04:54.880
and its power draw it blitzed through our testing suite pulling off similar

00:04:52.720 --> 00:05:02.400
per thread performance numbers to its fewer core brethren and even beating out

00:04:57.440 --> 00:05:03.840
our 22 core xeon e5 2699 v4

00:05:02.400 --> 00:05:10.639
and it managed to pull 500 to 600 watts on

00:05:07.600 --> 00:05:13.440
its own when overclocked it doesn't win

00:05:10.639 --> 00:05:17.280
any bang for the buck gaming awards but for those that need this kind of

00:05:14.880 --> 00:05:21.600
performance be they video editors 3d animators using fluid simulation or

00:05:19.919 --> 00:05:25.680
anyone who's doing high-end computational work that can't be

00:05:23.520 --> 00:05:30.000
offloaded onto a GPU well it could be that for you

00:05:28.080 --> 00:05:35.440
raw performance is all that matters because time is money and a CPU that

00:05:32.560 --> 00:05:40.320
outputs faster can pay for itself pretty quickly skylake x represents a healthy

00:05:38.320 --> 00:05:44.240
improvement upon the previous generation and it's a solid choice when it comes to

00:05:42.240 --> 00:05:49.039
both per thread and multi-threaded performance now we just hope that

00:05:46.240 --> 00:05:53.039
Intel's plan for a more dynamic and risky future brings us even more

00:05:51.199 --> 00:05:57.759
performance next year and the year after that

00:05:54.800 --> 00:06:00.240
because we're insatiable like that so thanks for watching guys if you
