remember how before this thing got wrecked we compared it to a custom core
i9 pc determining that the consumer hardware was a better value
well those skylake w chips are not exclusive
to the imac pro so what if you were to put one of them in a
pc what is a xeon w and how does Intel
justify the hefty premium that you would pay over a desktop core i9
we're not sure what we do know though is origin pc
sponsored today's video origin offers beautiful custom desktops laptops and
lifetime 24 7 technical support they use only high quality products like
samsung's 960 pro m.2 ssds and you can visit origin pc through the link below
for a limited time offer
so i've got two benches here for us today both of them are running very
similar ASUS workstation boards like
i wouldn't call these guys brother and sister but
if they were cousins they probably wouldn't want to get married so there's
the x 299 sage that's running the x 299
chipset that you're probably already familiar with and the other one is
running a chipset that Intel calls c422 and you will need
a c422 board if you want to run a xeon w
so with this chipset the main thing that you gain is support
for vpro whose claim to fame among other things is remote management with the
convenience and vulnerability that comes along with
that what you lose is support for Intel's
optane storage acceleration otherwise they are pretty similar in
their capabilities another feature of z w is official support for up to
512 gigabytes of system memory though
it should be noted that some x299 motherboards are compatible with
registered dimms meaning that they can
also run 512 gigs of RAM with a regular
core i9 so then if it wasn't for Intel making ecc a xeon
exclusive feature um there wouldn't really appear to be any
difference between them whatsoever
now ecc memory which we've actually covered in more depth before here
is not faster than regular RAM
what makes it special and what makes it more expensive is the fact that on the
fly it can actually check for and correct errors improving overall system
reliability this is a desirable feature for any system that's running mission
critical applications as for the cpus themselves well with a
couple of exceptions they line up almost one to one with the core x series lineup
which is to say they've got the same cache the same core counts and they even
fit in the same socket where they differ
is in the xeons gaining an extra four pci express lanes while losing support
for turbo boost max though it should be noted that many of
them have a higher turbo boost 2.0 speed
to compensate making that last bit sort of a non-issue and also kind of
raising the question as to why we have to have a software
application that only works in Windows for the desktop processors anyway
so with both benches assembled all that's left now is to do a little bit of
tuning to make sure that our tests are fair the main thing is just to make sure that
our memory is running at the same speed which it is
so to recap here are the hardware configurations that we're running today
now let's run some benchmarks starting with our two eight core chips to see if
maybe just maybe there is something that we have
overlooked yeah okay
moving on to our other tests we see the slight difference a 100 megahertz higher
base clock makes for gaming actually giving the xeon w2145
an edge over its core i7 counterpart so
that's good news if you were concerned that your serious business workstation
wouldn't be able to game off hours you can put those fears to rest and then as
for the heavy multi-threaded tests like blender the differences shrink down to a
maximum of 16 seconds and don't really seem to get any worse
over time meaning that the difference basically comes down to how high and for
how long the chips boost during the early phase of the run thanks to their
slightly different turbo implementations so i guess it's time for us to do a
quick chip swap here now we're on to our second pair and just
like the previous ones the differences aren't exactly striking
neither chip really seems to gain a firm
advantage over the other and it's a dead heat in our synthetic gaming tests once
again lightly threaded workloads favor turbo boost max and our numbers tighten
up considerably when we pour on the juice in blender
this time however we've got a maximum delta of about a minute with the 7 900
taking the crown on the gooseberry render
let's try the heavyweights now shall we we've got both systems loaded up with
their 18 core variants
so which monster CPU is more monstrous well
surprisingly our 7980 wrecked the xeon
w2195 in deus ex thanks to its higher
base and turbo boost clocks and while it's not as big a victory as
in our synthetic gaming tests it's still a win for the core i9 and then
it's the same story across the rest of our tests regardless of threading
we also saw our biggest upset in blender
with the core i9 winning by over a minute and a half
on the gooseberry render so
if the performance is as similar
in real life as the spec sheets would
seem to indicate with neither the consumer chips pulling
ahead in consumer workloads like games
nor the workstation chips pulling ahead in workstation workloads
it makes it honestly pretty difficult for me to wrap my head around the reason
that this lineup of cpus
and this chipset exists
now traditionally xeons based on the consumer 11 xx sockets
only had ecc as their main selling point
but those came at a relatively small premium
whereas again traditionally the expensive xeons with many cores well
they had the ability to run on dual socket boards as an easy justification
but this generation lacks that capability meaning that unless you
absolutely need the pro and ecc memory
support the latter being something that AMD's entire lineup from ryzen 3 to
threadripper supports natively and the former being something that Intel's own
consumer products support
it kind of smells like mostly marketing but uh
with a subtle undertone of extra pci express lanes
so at the end of the day i think what it comes down to is that
xeon has a lot more brand recognition
than core does in the workstation and
enterprise space so if Intel can charge
more for it i guess they might as well
but for our viewers i'll say this as long as you don't stand to lose a
hundred bucks worth of work every time your system
blue screens due to a bit flip
we're recommending to stick with the consumer core i9
private internet access supports a variety of vpn protocols and types of
encryption and authentication which allows you to dial in exactly the level
of privacy protection you need here's just a few reasons why you should use
pia vpn it offers ip cloaking so you can
hide your true ip address and geographic location it allows you to browse
anonymously keeping your identity hidden it allows you to avoid data mining and
targeted advertising and block unwanted connections with advanced
firewall and filtering capabilities to keep all network intrusions out so check
