Hi guys so I've had this requested quite a few times can you please compare this
Xiaomi Mi notebook Air the 13 inch version the
new revised one with the i-5 8250U 8 gigabytes of RAM and the 256 gigabytes
of storage to the larger Pro model which I have right here now if you've seen my
review of this one you would have probably seen me comment finally at the
end of it that I said that this model is just far superior and I'm basically
going to point out why now when we have a look at them side-by-side this spec is
the saying but there is a difference on the RAM so the configuration of both of
these is the 8 gigabytes of RAM however its dual channel on this pro model and
only running in single channel here so that's going to take a bit of a
performance hit on that 13 inch model now the other thing to point out is that
both of these if you're going to get one of these that it will ship if it's
shipping with a sealed box it will come with Windows 10 in Chinese now you can
upgrade to Windows 10 Pro for very cheap get one of those CD keys online and that
will save you the hassle of drivers and also losing the recovery partition when
you do reset the PC it will actually have that language pack on there that
you've installed so that's great to know that now looking at the obvious here the
size between both of these you can see that this has a much smaller footprint
here 13 inch model now this one is about 14.5 a millimeters thin that's not
including the little feet on the rear and then the 13.3 inch model this is
around 13.5 so there's only a one millimeter difference in thickness which
is quite amazing that they've managed to do that here now
the weight of them so we've got one point three two kilos as the 13.3 inch
model and then it is 2 kilos almost so it's about 1.9 8 kilos for the 15.6 inch
model and this is really stating the obvious it's why we get this model the
13 inch one really especially after what i'm going to show you now in this video
that you get it for the size the portability and the weight because
almost 2 kilos is just way too heavy for some people when you consider you
powerpack which is about another 180 grams or so more on top of that just to
cover things that are basically the same with them so the trackpad is obviously
way way lighter on the 15.6 inch model and that makes it a little bit more
comfortable but the accuracy and the use of it is basically exactly the same same
goes for that fingerprint reader so fingerprint unlocking it's blistering
fast I mean it only takes literally a second to unlock second or two and
you're straight into Windows which is really good now the keyboards okay so
the newer model does have the improved keyboard so the plastic they've used is
slightly better and it just makes it easier to look at those backlit keyboard
too with the black instead of the silver on the previous model which is a good
move there by Xiaomi so overall the keyboard okay typing on
the 15.6 inch version does just feels so much better because the keys
have a bit of feedback to them they have a slight curve to them inwards on them
just making them even ever so slightly more comfortable there to type on not
the 13.6 and sorry 13.3 inch keyboard is bad to type on no not at all it's a good
tip what keyboard to type on and it's comfortable as well for the size port
wise if we have a look here they're basically the same you just get the
extra SD card reader on the pro and you also get a USB 3 type C port so both the
type-c ports on these two models they support up to 4k 60 Hertz output and
HDMI ports you can see here well they only support up to 30 Hertz 4k out
because they're hdmi 1.4 spec and not hdmi 2 so sadly both of these models are
missing Thunderbolt 3 which they should definitely have and that's a big mistake
from show me not to include that now to take a look at the internals of them
both of them have these separate spear SSD slots on here so it will take either
pci x 4 or SATA 3 drives on there the 2280 spec now the battery difference is
massive of course because look at how small it is compared to the 15.6 inch
model the 13 inch model you can see with the battery there is only 39 watt hours
so knowing air is big and then having a look now at the
cooling you can see we've got a smaller fan and a slightly larger fan and the
same copper thermal transfer pipe so this is why we've got some limitations
there on the cooling and then if you have a look now at the 15.6 inch model
we have a massive sixty watt hour battery so to speak about the battery
life - you can get up to ten hours of light web use on the 15.6 inch model and
about six six and a half on the 13.3 inch model so there is a huge difference
of course because of the large different capacity there are those batteries
because one is way big almost double the size there now looking at the cooling
tote on the pro you'll see that we've got larger fans and they are separate -
fans there so really good cooling on this it does the job well and you don't
only see the GPU go over 74 degrees and the CPU should never really go over
about 78 80 or so so cooling does do its job really well but on the other hand on
this 13.3 inch model you run into thermal throttling all the time if you
do anything demanding which chum we'll talk about a little bit more now in
detail okay so even though they do have the same chipset the i5 8250 you I've
got these stock values on everything so I haven't and tweaked or changed under
voltage or done any of that nothing to the power limits and you can see it is
quite a bit of a difference here now the reason is because one of them is running
single channel RAM which is of course the smaller model that is why we have
this difference here you can see it's taken quite a hit on the performance
when you check out a synthetic benchmark here this is Geekbench for the same
applies to anything across the board you'll have similar results so you're
going to see a difference anywhere from around 10% to almost up to around 20
percent performance head because of the single channel ram and because of
thermals it runs into thermal throttling which I'll show you in just a second so
those are the cpu scores here now if I move over and show you the GPU that's
more or less exactly the same so no real difference here until you start to game
now when you're game it will not turbo as high the MX 150 in the 13-inch model
because of the thermals it runs into more restriction
there and it's actually clocked a little bit lower too so that is why but if you
want more details on that like I've said in this review here please check out the
full reviews of each of these models here now just to quickly go over to
Intel XTU this is quite interesting here just to point out what happens on both
of these and how different they really are very different in terms of the
cooling performance of course different sizes here the advantage goes to of
course the larger model but if we have a look I ran that Geekbench for test and
you'll see right here that we ran into it's a bit a little bit hard to make out
on camera sorry otis zoom into this for you then we ran into some thermal
throttling here on the 13-inch model and you can see that yellow bar here is
actually the thermal throttling that was happening so that was the whole time
going on and off from thermal throttling and you'll see here that it peaked with
the dick bent for test at 80 degrees Celsius and if I move over now and we'll
have a look at the 15 inch model that one really interesting here it only
peaked at 57 sorry 64 I think was the maximum no CS 64 degrees Celsius and
that did not run into any thermal throttling now I haven't got it selected
there to show you about trust me it didn't run into it at all because
thermal throttling is triggered around about I think it's 73 degrees at least
on the 13-inch model so there is a big difference there and the thermals and
the performance of that as I pointed out in my review of the 13-inch model quite
disappointed with the fact that you know they're the same chip but they are just
really different beasts here when it comes to it now SSD performance they're
both running the Samsung PM 961 as I pointed out at the start and more or
less the same kind of speeds but you will see that it is faster the reads on
the 15.6 inch model it could be down to the drive or it could be down to the
fact that we do have slightly faster CPU performance on that one so just to show
you here the BIOS versions of each so I haven't changed the biased version this
is what they have come with so you can see there that's the bank 0 we've only
got the 8 gigabytes of RAM in single channel on the 13 inch model and then if
I move over now of course to the 15 inch model
you will see that it has bank one will Bank zero sorry and in bank two full so
four gigabytes each running in dual channel and here is the bios version so
to point out this bias version is actually a newer one that's come with
this model it says it's dated from the second of November but what's
interesting to point out is that the core and Intel XT you it will give me
full controls here so I can adjust the voltage and also the power limits now
what happened is later on they locked us out of this and a few of the revisions
of that bias but it seems that xiaomi's change their mind again and decided to
let us play around with it now this is really good because it allows you on the
fifty-ninth model to increase the turbo boost max power you can put that up to
something like 35 and it will perform really well it will hold the 3.4 turbo
on all calls for it as long as it wants really as long as it can and you
shouldn't run into actually any soon was rotting as long as you give it a little
bit of an under vault now the same goes for the smaller version but it's kind of
pointless to do this even though the power limits are unlocked as I will show
you you can see here they are are not so you can tweak that up to 35 watts but
there's no point whatsoever because you will hit thermal throttling in a matter
of seconds so you get zero gains so if you must have the best performance go
for the 15.6 inch model so with the screen side-by-side you can see there's
a clear difference this should be coming out on the video that if you have a look
at the 13-inch model you will notice that the blacks look deeper now the
13-inch model has an sRGB of somewhere around 84% I think it is and then 78% on
the 15.6 inch model I mean they're not wonderful figures if you're
professionals out there you want to use this and you want full coverage then
you're gonna have to tweak the screen a little bit you're still not gonna be
able to get it out of these panels but these panels to me they are very decent
for 1080p panels of course they're covered with fully laminated glass there
and they are quite reflective but the blacks and the sharpness and the color
reproduction on the 13.3 inch model is where this one gets a win and it is
me the only one it will really get apart from of course the obvious the size and
the weight and there's also a little bit of light leakage and bleed on the 15.6
inch model that you get a little bit now this will vary from unit to unit you can
probably make it out here just on the edges
well that black has just a tiny little bit of that bleed or that leakage you
get on the corners and you really only see it when you're looking at a
completely black image that has been displayed so it has never bothered me
because I'm never looking at just a complete black screen ever on to sound
now so you probably guessed it that the 15-inch version does sound a little bit
richer full of the sound they're both AKG Troon speakers
downwards firing I'll give you a sample of both of them but hopefully with my
mic you will be able to pick up the difference now both of them are set to
100% volume
so you should have heard from that quick sample there that the 15.6 inch pro
model is not only louder but it does have quite a bit more bass to it now to
briefly touch on fan noise differently the 15.6 inch model runs cooler of
course so the fans come on a lot less you hardly even hear the now right now
both of these machines are basically idle and for some reason the 13 inch
version the fan is running anywhere between about 60 and 80% and I don't
even think the fan is on the 15.6 inch model it doesn't take anything for the
13-inch model for the fan to come on so even when you sometimes just an internet
explorer which while I can re am at the moment this is enough for that fan to be
triggered and I even posted that in my cons of the review of the 13-inch 2018
model that the fan noise is a little bit annoying and irritating at times and if
fanless bothers you then definitely I would stay clear of it because it can
just get a little bit annoying because sometimes it's like well I'm not even
doing anything demanding why is that fan constantly on
and again it's because of the cooling limitations in the smaller model okay so
really easy to wrap things up here you would go for this model if you want this
slightly a bit of screen slightly sharper bit of contrast a bit of blacks
and it doesn't have as much way in fact this panel has no IPS bleed around the
edges none of that no which is great the size of it of course is so much smaller
and it's so much lighter so that's probably the main reason why someone
would even consider this model over the 15.6 inch model for me the compromise is
worth it okay yeah it's almost 2 kilos which is starting to get a little heavy
especially for the type of a laptop it is but the improved calling the cooling
sorry on it is just so much better thermal throttling on this one no
thermal throttling on this whatsoever the fact that I can tweak up the power
limit and get it to perform pretty much the same as an i7 7700 HQ is pretty
amazing too for that keyboards great touchpad is basically the same but the
largest size just makes it so much more usable we do get an extra port
SD card reader is a nice bonus to have on this for professionals out there that
if you forgot your reader even though it's limited to only USB two speeds it
still of course handy to have so yes performance everything this one
is the clear winner apart from size weight and screen thanks
a lot for watching this review now I didn't go into super amounts of detail
in this particular video if you want detailed reviews of both of these models
then please check out my reviews here so review of the mi notebook air 13 the
2018 Edition is right up here and then my Mi notebook Pro 15.6 inch model this
is the i5 version that reviews right here thanks a lot for watching and I do
have to catch you back in the channel soon bye for now
