WEBVTT 00:00:00.040 --> 00:00:06.040 Linus Tech tips coverage of CES 2015 is brought to you by Phantom glass visit 00:00:04.400 --> 00:00:11.320 store. phantom.in screen protectors out there 00:00:08.400 --> 00:00:16.279 as well as hyperx so here it is guys AMD free sync a year late and a dollar short 00:00:14.559 --> 00:00:20.160 although that's not necessarily A Bad Thing it did take a year compared to 00:00:18.279 --> 00:00:25.560 NVIDIA's g-sync and it's a lot more than a dollar short the main benefit that AMD 00:00:22.840 --> 00:00:30.759 is touting for free sync is that first four letters the whole free thing so as 00:00:28.240 --> 00:00:34.960 long as you have an AMD GPU and as long as the monitor has a scaler with a 00:00:32.759 --> 00:00:40.320 firmware that supports free sync there is no additional cost compared to any 00:00:38.160 --> 00:00:45.719 other high-end monitor that has a decent scaler in it that also has a variable 00:00:42.960 --> 00:00:51.360 refresh rate panel so compared to g-sync which actually has an over $100 module 00:00:49.199 --> 00:00:54.280 cost that goes along with the monitor freesync doesn't cost extra and it 00:00:53.120 --> 00:01:00.399 actually comes with a couple of other benefits that they're talking about as well while freesync variable refresh 00:00:57.920 --> 00:01:05.239 rate technology is not supported on on HDMI or DVI or any of those more 00:01:02.719 --> 00:01:09.600 traditional inputs the monitor can at least support them without free sync you 00:01:07.560 --> 00:01:15.159 will need to run DisplayPort for free sync to function now if this sounds very 00:01:13.040 --> 00:01:19.439 sort of you know too good to be true actually it gets even better so unlike 00:01:17.520 --> 00:01:24.079 g-sync AMD is launching they're going to have sometime in the next quarter or so 00:01:21.720 --> 00:01:27.640 12 monitors already with freesync and I kind of went well how did you get so 00:01:25.360 --> 00:01:31.159 many when g-sync is still struggling to get a ton of support and the answer is 00:01:29.320 --> 00:01:34.680 well because it doesn't actually cost the monitor vendors anything extra and 00:01:32.799 --> 00:01:38.320 gives them an additional value ad and you might go okay well what's the value 00:01:36.240 --> 00:01:42.439 ad what exactly is this free sync from AMD g-sync from NVIDIA thing and the 00:01:40.759 --> 00:01:47.600 answer is it's variable refresh rate technology so when your GPU is 00:01:44.320 --> 00:01:50.920 outputting at exactly 144 frames per 00:01:47.600 --> 00:01:53.560 second so this is a 27 in 144 HZ monitor 00:01:50.920 --> 00:01:57.360 if your GPU could output at exactly 144 frames per second exactly evenly and 00:01:55.560 --> 00:02:02.079 smoothly all the time then you would never experience what's called tearing 00:02:00.039 --> 00:02:05.320 if the frame rate goes too high or too low you can experience a phenomenon 00:02:04.200 --> 00:02:09.479 called tearing where it's actually showing part of the you know the last 00:02:07.520 --> 00:02:12.440 frame that was rendered up here and part of the next frame down here and they can 00:02:10.920 --> 00:02:17.200 be kind of separated from each other and particularly when moving fast this can 00:02:14.640 --> 00:02:22.120 be very visually distracting especially in certain games so free sync totally 00:02:20.239 --> 00:02:27.239 eliminates that by allowing the monitor to refresh every time the GPU outputs a 00:02:24.480 --> 00:02:30.720 frame to it now it's not perfect and something that you might even be able to 00:02:28.560 --> 00:02:36.720 see right now is that depending on the implementation from the monitor vendors 00:02:33.319 --> 00:02:39.200 you will see either freey disable at 00:02:36.720 --> 00:02:43.879 somewhere in the range of maybe 40 HZ or somewhere in the range of maybe you know 00:02:41.480 --> 00:02:48.080 30 htz where it'll actually if the game frame rate drops below that range freyn 00:02:46.879 --> 00:02:52.120 will actually disable and you will see a little bit of tearing but this is not an 00:02:50.000 --> 00:02:55.920 inherent limitation of freey this is a limitation of the panel technology once 00:02:54.560 --> 00:03:00.120 you start to refresh them extremely slowly you're going to get flickering 00:02:58.239 --> 00:03:04.720 rather than tearing and that can can be even less desirable especially if you 00:03:02.560 --> 00:03:08.760 dip below that quite frequently it'll be very distracting to your eyes so 00:03:06.440 --> 00:03:12.799 freesync actually supports refresh rates as low as 9 Hertz but we're not going to 00:03:10.879 --> 00:03:15.920 see anything like that today so you kind of go okay there's 12 monitors or 00:03:14.560 --> 00:03:18.879 something like that they're promising up to 20 by the end of the year but what 00:03:17.720 --> 00:03:23.440 kind of monitors are we getting are we getting a bunch of 1080 ptn panels no 00:03:21.680 --> 00:03:29.000 actually AMD has a cross-section of different monitors right here in their 00:03:25.000 --> 00:03:30.120 Booth so this is the BenQ XL 2730 Z I'm 00:03:29.000 --> 00:03:37.760 going to try and get all these model names right this is a 27in 2560 00:03:33.280 --> 00:03:39.200 x600 TN panel and it runs at 144 Herz so 00:03:37.760 --> 00:03:42.159 I was getting the look is he going to miss the refresh rate that's really 00:03:40.760 --> 00:03:48.239 important because this is going to this looks like it's going to be a great competitor for something like the ASUS R 00:03:45.159 --> 00:03:51.799 OG Swift this one right here is the 00:03:48.239 --> 00:03:56.519 Samsung uee 590 I sure hope that's right 00:03:51.799 --> 00:03:59.000 yeah it is 28 in 4k 60 HZ and this one 00:03:56.519 --> 00:04:02.480 is not a TN panel this is actually a VA type panel they've actually got their 00:04:00.400 --> 00:04:06.840 demo running here where you can much like we've already seen with NVIDIA's 00:04:04.280 --> 00:04:12.599 pendulum demo you can switch between oh I don't know 45 FPS and 60 FPS and you 00:04:10.560 --> 00:04:17.600 can do sweeping FPS it can change all the time and you can actually see very 00:04:14.040 --> 00:04:19.560 visually if I turn free sync off whoa 00:04:17.600 --> 00:04:24.280 that's ugly and this is not a faked demo you've probably seen this especially 00:04:21.199 --> 00:04:27.360 games like Skyrim man that game Tears 00:04:24.280 --> 00:04:29.840 like a this one right over here is 00:04:27.360 --> 00:04:34.880 the LG this is the 00:04:31.600 --> 00:04:37.960 2967 yeah nailed it so that's a 2560 by 00:04:34.880 --> 00:04:40.039 1080 IPS monitor we've actually reviewed 00:04:37.960 --> 00:04:44.320 it's little nonf freesync enabled brother I'm personally a huge fan of the 00:04:42.039 --> 00:04:48.919 whole ultrawide thing but not a big fan of 10 10,080 vertical pixels but don't 00:04:47.360 --> 00:04:56.039 worry LG is actually showing off hopefully we're going to be checking that out tomorrow in their Booth the 34 00:04:52.479 --> 00:04:58.800 in 3440 x440 version of this monitor 00:04:56.039 --> 00:05:04.120 that is also 60 HZ also free sync enabled so it is an extremely exciting 00:05:01.759 --> 00:05:08.639 time for at least the folks at AMD who want people buying AMD graphics cards 00:05:06.320 --> 00:05:11.600 and having that uh that variable refresh rate feature that is the kind of thing 00:05:09.840 --> 00:05:15.440 that's hard to sell to people because unless they've seen it before it's hard 00:05:13.759 --> 00:05:20.479 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 00:05:19.199 --> 00:05:24.360 however long you've been a gamer putting up with tearing so I think that pretty 00:05:22.639 --> 00:05:28.080 much wraps it up that is the definitely the most exciting thing here at the AMD 00:05:26.080 --> 00:05:30.840 Booth guys don't miss any of our CES coverage click that subscribe button so 00:05:29.759 --> 00:05:35.120 you don't miss any of it and I do want to take a moment to thank our sponsors 00:05:33.600 --> 00:05:39.680 Phantom glass these guys make the best darn screen protectors on the market 00:05:37.400 --> 00:05:42.680 they're super clear they feel just like the glass that's on your phone and 00:05:40.840 --> 00:05:45.479 there's no great secret to that it's because it's actually made of Gorilla 00:05:44.120 --> 00:05:49.639 Glass they've got a nano coating on the bottom that allows it to be applied with 00:05:47.360 --> 00:05:53.400 absolutely no bubbles effortlessly and makes it reusable so if you got to RMA 00:05:51.639 --> 00:05:57.520 your phone you can actually take it off wrap it up something get your phone back 00:05:55.280 --> 00:06:00.160 reapply it and you are ready to rock as well as oh yeah you want to check out 00:05:59.160 --> 00:06:05.319 store phantom.in in the video description you want to check that out they've got 00:06:03.520 --> 00:06:08.560 covers for lots of different phones as
