as well as hyperx so here it is guys AMD free sync a year late and a dollar short
although that's not necessarily A Bad Thing it did take a year compared to
NVIDIA's g-sync and it's a lot more than a dollar short the main benefit that AMD
is touting for free sync is that first four letters the whole free thing so as
long as you have an AMD GPU and as long as the monitor has a scaler with a
firmware that supports free sync there is no additional cost compared to any
other high-end monitor that has a decent scaler in it that also has a variable
refresh rate panel so compared to g-sync which actually has an over $100 module
cost that goes along with the monitor freesync doesn't cost extra and it
actually comes with a couple of other benefits that they're talking about as well while freesync variable refresh
rate technology is not supported on on HDMI or DVI or any of those more
traditional inputs the monitor can at least support them without free sync you
will need to run DisplayPort for free sync to function now if this sounds very
sort of you know too good to be true actually it gets even better so unlike
g-sync AMD is launching they're going to have sometime in the next quarter or so
12 monitors already with freesync and I kind of went well how did you get so
many when g-sync is still struggling to get a ton of support and the answer is
well because it doesn't actually cost the monitor vendors anything extra and
gives them an additional value ad and you might go okay well what's the value
ad what exactly is this free sync from AMD g-sync from NVIDIA thing and the
answer is it's variable refresh rate technology so when your GPU is
outputting at exactly 144 frames per
second so this is a 27 in 144 HZ monitor
if your GPU could output at exactly 144 frames per second exactly evenly and
smoothly all the time then you would never experience what's called tearing
if the frame rate goes too high or too low you can experience a phenomenon
called tearing where it's actually showing part of the you know the last
frame that was rendered up here and part of the next frame down here and they can
be kind of separated from each other and particularly when moving fast this can
be very visually distracting especially in certain games so free sync totally
eliminates that by allowing the monitor to refresh every time the GPU outputs a
frame to it now it's not perfect and something that you might even be able to
see right now is that depending on the implementation from the monitor vendors
you will see either freey disable at
somewhere in the range of maybe 40 HZ or somewhere in the range of maybe you know
30 htz where it'll actually if the game frame rate drops below that range freyn
will actually disable and you will see a little bit of tearing but this is not an
inherent limitation of freey this is a limitation of the panel technology once
you start to refresh them extremely slowly you're going to get flickering
rather than tearing and that can can be even less desirable especially if you
dip below that quite frequently it'll be very distracting to your eyes so
freesync actually supports refresh rates as low as 9 Hertz but we're not going to
see anything like that today so you kind of go okay there's 12 monitors or
something like that they're promising up to 20 by the end of the year but what
kind of monitors are we getting are we getting a bunch of 1080 ptn panels no
actually AMD has a cross-section of different monitors right here in their
Booth so this is the BenQ XL 2730 Z I'm
going to try and get all these model names right this is a 27in 2560
x600 TN panel and it runs at 144 Herz so
I was getting the look is he going to miss the refresh rate that's really
important because this is going to this looks like it's going to be a great competitor for something like the ASUS R
OG Swift this one right here is the
Samsung uee 590 I sure hope that's right
yeah it is 28 in 4k 60 HZ and this one
is not a TN panel this is actually a VA type panel they've actually got their
demo running here where you can much like we've already seen with NVIDIA's
pendulum demo you can switch between oh I don't know 45 FPS and 60 FPS and you
can do sweeping FPS it can change all the time and you can actually see very
visually if I turn free sync off whoa
that's ugly and this is not a faked demo you've probably seen this especially
games like Skyrim man that game Tears
like a this one right over here is
the LG this is the
2967 yeah nailed it so that's a 2560 by
1080 IPS monitor we've actually reviewed
it's little nonf freesync enabled brother I'm personally a huge fan of the
whole ultrawide thing but not a big fan of 10 10,080 vertical pixels but don't
worry LG is actually showing off hopefully we're going to be checking that out tomorrow in their Booth the 34
in 3440 x440 version of this monitor
that is also 60 HZ also free sync enabled so it is an extremely exciting
time for at least the folks at AMD who want people buying AMD graphics cards
and having that uh that variable refresh rate feature that is the kind of thing
that's hard to sell to people because unless they've seen it before it's hard
to understand why you would even care about something that you've been putting up with for the last 5 10 or 20 years or
however long you've been a gamer putting up with tearing so I think that pretty
much wraps it up that is the definitely the most exciting thing here at the AMD
Booth guys don't miss any of our CES coverage click that subscribe button so
you don't miss any of it and I do want to take a moment to thank our sponsors
Phantom glass these guys make the best darn screen protectors on the market
they're super clear they feel just like the glass that's on your phone and
there's no great secret to that it's because it's actually made of Gorilla
Glass they've got a nano coating on the bottom that allows it to be applied with
absolutely no bubbles effortlessly and makes it reusable so if you got to RMA
your phone you can actually take it off wrap it up something get your phone back
reapply it and you are ready to rock as well as oh yeah you want to check out
store phantom.in in the video description you want to check that out they've got
covers for lots of different phones as well as hyperx they are also sponsoring
our trip to the show here you're going to want to check out youtube.com/ hyperx
for all the great gaming content that they've got going on that's also linked
in the video description thanks for watching guys and we'll see you at our next CES 2015 video
