WEBVTT

00:00:00.160 --> 00:00:09.519
what is this last gen crap AMD

00:00:04.319 --> 00:00:12.080
where is my next gen zen 3 Threadripper

00:00:09.519 --> 00:00:17.880
well as it turns out AMD themselves might not know yet because their new

00:00:14.480 --> 00:00:20.640
milan zen 3 epic processors look so

00:00:17.880 --> 00:00:25.359
ridiculously overpowered that it's kind of hard to see where threadripper or

00:00:22.720 --> 00:00:30.640
Intel for that matter fits in anymore so i'm actually starting to understand why

00:00:27.760 --> 00:00:35.920
they took a serious business data center product and gave it this misspelled

00:00:33.200 --> 00:00:35.920
gamery name

00:00:37.200 --> 00:00:43.680
cause they knew it would be so let's dig through this absolutely huge

00:00:41.760 --> 00:00:48.960
announcement and then see if we can make some educated guesses about where AMD

00:00:46.399 --> 00:00:51.920
goes next just like you guessed i'd be making this segue to our sponsor

00:00:50.719 --> 00:00:56.559
seasonic never skimp on getting a quality power

00:00:53.840 --> 00:01:00.079
supply for your rig check out csonic to find award-winning power supplies and

00:00:58.399 --> 00:01:03.920
try out their wattage calculator to see which one will suit your needs down

00:01:01.920 --> 00:01:06.920
below yeah it'll suit you down below needs

00:01:13.920 --> 00:01:21.439
AMD's ryzen 5000 cpus propelled them to the forefront of desktop performance and

00:01:19.360 --> 00:01:27.040
now they're looking to bring that same special sauce to the enterprise with

00:01:23.600 --> 00:01:29.280
milan their third generation epic lineup

00:01:27.040 --> 00:01:34.159
now to say that AMD has completely leapfrogged Intel here would be an

00:01:31.280 --> 00:01:39.840
injustice one cannot leapfrog that which one has already

00:01:36.640 --> 00:01:41.680
frog loped okay and based on the numbers

00:01:39.840 --> 00:01:46.079
that AMD is showing here they are going to have as much as double the

00:01:43.520 --> 00:01:50.720
performance or more depending on the workloads compared to their competition

00:01:48.640 --> 00:01:55.520
this is largely thanks to the zen 3 architecture which provides a healthy

00:01:52.479 --> 00:01:58.240
uplift in performance per clock or ipc

00:01:55.520 --> 00:02:03.040
over zen 2. now we did a brief explainer on how they managed this in our ryzen

00:02:00.079 --> 00:02:06.799
5000 series review but as a refresher nearly 50 percent of the improvement

00:02:04.880 --> 00:02:10.160
comes from load store and front-end improvements with adjustments to the

00:02:08.560 --> 00:02:15.200
cash and branch prediction picking up most of the rest as AMD points out not

00:02:12.959 --> 00:02:19.680
only do they now have a full 32 megabytes of level 3 cache shared across

00:02:17.360 --> 00:02:25.440
up to 8 cores and a retooled layout that no longer splits groups of cores up in

00:02:21.840 --> 00:02:27.840
compute complexes or ccx's but instead

00:02:25.440 --> 00:02:33.200
of doing one load and one store per cycle the new pipeline is now also

00:02:30.319 --> 00:02:39.840
capable of doing up to three loads and two stores per cycle which as you can

00:02:35.840 --> 00:02:41.840
imagine well doubling anything is

00:02:39.840 --> 00:02:46.800
a big freaking deal especially for crunching a lot of data

00:02:44.319 --> 00:02:50.720
what's more they have four more table walkers for a total of six now which

00:02:48.720 --> 00:02:55.280
means that heavy database workloads that rely on lookup tables will be

00:02:52.560 --> 00:02:59.680
significantly sped up again big freaking deal for the enterprise

00:02:57.440 --> 00:03:05.680
because when you're say twitter or reddit you have got a lot of data to

00:03:03.120 --> 00:03:09.599
sift through most of it garbage but it's a lot of data

00:03:07.599 --> 00:03:14.000
and that's not all AMD is also increasing the number of skus available

00:03:11.360 --> 00:03:19.760
to a total of 19 with anywhere from one to eight cores per die and all but four

00:03:17.200 --> 00:03:26.000
of them are dual socket capable that is really scary for Intel who already needs

00:03:22.640 --> 00:03:28.000
two sockets to compete with AMD's one

00:03:26.000 --> 00:03:32.000
now of the skus that are dual socket capable there are four that are

00:03:29.760 --> 00:03:36.319
specifically optimized for per thread performance which not only gives them

00:03:34.319 --> 00:03:41.760
higher clocks than the rest of the stack but they also get as much level 3 cache

00:03:38.720 --> 00:03:44.239
as possible per core and the performance

00:03:41.760 --> 00:03:48.959
implications here can't be overstated these cpus are probably what will end up

00:03:46.799 --> 00:03:53.599
forming the basis of zen 3 based threadripper cpus for enthusiasts and

00:03:51.280 --> 00:03:57.680
workstation users regardless of core count and socket compatibility all of

00:03:55.599 --> 00:04:01.439
these new epics share the same features including drop in compatibility with

00:03:59.439 --> 00:04:06.159
previous generation epic boards a little more than a BIOS update and oh this is

00:04:03.760 --> 00:04:10.959
pretty cool epic can now take advantage of 4 channel 6 channel and 8 channel

00:04:09.200 --> 00:04:15.599
memory which substantially improves flexibility in deployment flexible like

00:04:13.200 --> 00:04:20.239
our underwear at ltdstore.com there it is now of course epic has

00:04:17.919 --> 00:04:24.320
always been AMD's server and data center play and they seem really proud of the

00:04:22.800 --> 00:04:28.560
sheer compute power that they can bring to bear which can reduce total cost of

00:04:26.400 --> 00:04:32.960
ownership through just increasing the density and lowering the requirements

00:04:30.720 --> 00:04:37.040
for software licenses in a deployment but they're also laser focused on the

00:04:35.040 --> 00:04:41.520
ecosystem itself which they referred to as the third leg of the stool i mean

00:04:39.680 --> 00:04:44.960
some people have a you know four-legged stool and if they didn't have one it'd

00:04:42.880 --> 00:04:48.400
be fine but i guess they don't one of the biggest aspects of this has been

00:04:46.800 --> 00:04:52.320
improving security through hardware features they've created a fully

00:04:50.240 --> 00:04:57.759
authenticated boot process starting from before the CPU ever even hits x86 BIOS

00:04:55.600 --> 00:05:02.240
or operating system code they've also implemented secure nested paging meaning

00:05:00.160 --> 00:05:06.880
that an operating system in a virtual machine is now protected against an

00:05:04.479 --> 00:05:12.000
insecure hypervisor so that's the operating system that hosts the virtual

00:05:09.199 --> 00:05:16.880
ones so for example if a server in a rack gets compromised somehow the guest

00:05:14.800 --> 00:05:21.680
virtual machine running on it will not be directly vulnerable which would be a

00:05:19.039 --> 00:05:25.919
huge deal for a vps host speaking of which we're going to try making our own

00:05:23.280 --> 00:05:29.120
google stadia using google cloud so uh get subscribed so you don't miss that

00:05:27.919 --> 00:05:34.479
gong show chances are though unless you're doing something crazy like making your own

00:05:32.400 --> 00:05:39.600
stadia you're not running a vps host at home so why don't we change gears and do

00:05:37.280 --> 00:05:44.160
a little bit of theory crafting here most people who need more than a ryzen

00:05:41.440 --> 00:05:48.240
desktop CPU will be running threadripper and because threadripper development

00:05:45.840 --> 00:05:52.000
tends to follow epic we can make a few predictions for how the next

00:05:49.520 --> 00:05:55.520
threadripper cpus might look it seems pretty safe to assume that the

00:05:53.759 --> 00:06:01.280
mainstream threadripper lineup will consist of skus based on the per thread

00:05:57.840 --> 00:06:04.160
optimized 24 core and 32 core epic skus

00:06:01.280 --> 00:06:10.240
with higher end 48 core and 64 core skus coming later unless maybe that doesn't

00:06:07.440 --> 00:06:14.880
happen because in the past we've seen thread vapors reach higher clock speeds

00:06:12.319 --> 00:06:19.199
than their epic counterparts but these new epic cpus could be a different story

00:06:17.360 --> 00:06:23.600
because their thermal and power consumption ratings are significantly

00:06:21.280 --> 00:06:28.639
higher than the second generation roam chips that they replace in fact they're

00:06:26.400 --> 00:06:33.919
kind of already in line with the threadripper 3000 series tdps which

00:06:31.919 --> 00:06:38.800
poses a bit of a problem without increasing the power consumption and

00:06:35.759 --> 00:06:39.680
heat output all the way like past 300

00:06:38.800 --> 00:06:47.440
watts how could AMD hope to increase clock speeds for their workstation products in

00:06:44.960 --> 00:06:52.800
order to get the threadripper 3970x to its rated clock AMD had to bump the TDP

00:06:49.919 --> 00:06:57.759
by 55 watts over the otherwise very similar epic 7742

00:06:55.440 --> 00:07:01.520
i mean surely there's not that much power taken up by the expanded memory

00:06:59.759 --> 00:07:07.919
controller and secure processor integrated into the i o die right so

00:07:04.960 --> 00:07:12.639
at these kinds of TDP increases we might not even be able to get a 64 core thread

00:07:10.639 --> 00:07:16.400
ripper assuming it needed higher clock speeds maybe AMD's already telegraphing

00:07:14.800 --> 00:07:19.599
their next play with the recent release of their threadripper pro platform i

00:07:18.240 --> 00:07:23.199
mean on the surface it didn't make a ton of sense right shiny new chipset and

00:07:22.000 --> 00:07:28.960
motherboards dusty old zentu architecture cpus

00:07:26.319 --> 00:07:34.800
so that could be it ryzen for consumers with lower core counts epic for servers

00:07:31.520 --> 00:07:36.880
and then these epic derived pro cpus and

00:07:34.800 --> 00:07:39.680
threadripper for consumers quietly goes away

00:07:38.000 --> 00:07:44.160
only time will tell for now we can only speculate and look

00:07:41.520 --> 00:07:47.840
forward to much faster top-end cpus than have previously been possible and tell

00:07:46.160 --> 00:07:51.039
you guys to make sure you're subscribed because we are hoping to have more

00:07:49.680 --> 00:07:54.720
coverage of these epic chips in the weeks to come once we can get hands-on

00:07:53.599 --> 00:07:58.560
with them and time will also tell whether Intel

00:07:56.720 --> 00:08:02.240
can catch up to what AMD's been able to accomplish here with their new

00:08:00.000 --> 00:08:07.440
leadership and old professionals coming back into the fold i'm actually really

00:08:04.800 --> 00:08:12.400
excited for competition to return for now though AMD enjoy your time at the

00:08:09.919 --> 00:08:16.479
top but don't get too comfortable don't become what you've tried so hard

00:08:13.840 --> 00:08:21.680
to destroy i mean just look at me i was supposed to destroy the segways
