00:00:05.680 --> 00:00:11.599
the Corsair carbide air 540 high airflow cube case is great for air cooling or

00:00:10.080 --> 00:00:15.519
liquid cooling check the link in the video description to learn more welcome

00:00:13.759 --> 00:00:20.080
to another unboxing today we've got the Radeon

00:00:17.240 --> 00:00:25.359
r7260x and what this card is if you don't feel like watching the rest of the

00:00:21.520 --> 00:00:28.000
video is basically a Radeon 7790

00:00:25.359 --> 00:00:32.000
but with some more features and with more performance so this is part of

00:00:30.080 --> 00:00:38.239
AMD's new generation of products which they're calling the r7 and r9 series r7

00:00:35.040 --> 00:00:40.800
refers to performance class gpus and r9

00:00:38.239 --> 00:00:44.879
refers to enthusiast class gpus so what is the key difference well one is price

00:00:42.800 --> 00:00:49.120
this sits in that sweet spot between 100 and 200 dollars where you can typically

00:00:46.800 --> 00:00:53.199
get some of the best bang for the buck the other difference is in well

00:00:50.960 --> 00:00:58.239
obviously performance so this card right here is not designed for you know three

00:00:55.760 --> 00:01:04.320
by 1080p ifinity setups or anything like that this is for gaming in modern titles

00:01:00.559 --> 00:01:06.640
at 1080p it has 896 stream processors it

00:01:04.320 --> 00:01:11.600
has two gigs of RAM and it is clocked at 1.1

00:01:08.159 --> 00:01:14.320
gigahertz on the core out of the box

00:01:11.600 --> 00:01:19.759
which is very very cool because it's the fastest stock GPU speed we've ever seen

00:01:17.439 --> 00:01:23.200
out of AMD it's got a typical board power of 115 watts so it's relatively

00:01:21.840 --> 00:01:27.759
low power consumption and that is reflected by the single pci express six

00:01:25.840 --> 00:01:31.360
pin connector on it you can also we'll do a quick tour of the card here where

00:01:29.200 --> 00:01:35.600
you can see that the the stock reference card is going to have a flower style

00:01:34.000 --> 00:01:40.479
heat sink so you can see there's going to be air flow coming from that single

00:01:37.280 --> 00:01:42.640
80 millimeter fan that is going to be

00:01:40.479 --> 00:01:46.720
just pushed down all over the card all over the memory in the vrm the vrm is

00:01:45.280 --> 00:01:50.000
the only part of the board other than the GPU itself that has a heat sink

00:01:48.640 --> 00:01:54.799
directly on it so you can see it's located up here near the front of the

00:01:51.759 --> 00:01:57.040
board it uses pci express 3.0 for

00:01:54.799 --> 00:02:00.159
connectivity although on cards of this caliber it doesn't really make much of a

00:01:58.479 --> 00:02:05.119
difference and on the back we've got the typical AMD layout two dual link dvi

00:02:02.719 --> 00:02:10.479
HDMI and DisplayPort but there's a big difference here AMD has changed the r7

00:02:07.680 --> 00:02:16.160
and r9 series to allow three displays at 1080p 60 hertz running off of dvi dvi

00:02:13.920 --> 00:02:20.800
and HDMI so you no longer need a displayport adapter very cool stuff next

00:02:18.959 --> 00:02:25.440
up we've got the crossfire connector which is present on the 260x and the

00:02:23.840 --> 00:02:28.879
back of the card where we don't see a whole lot there so let's talk about some

00:02:27.440 --> 00:02:32.080
of the technologies that are included before we hand things over to slick to

00:02:30.560 --> 00:02:36.480
tell us about the performance compared to the competition so number one is zero

00:02:34.160 --> 00:02:40.879
core zero core refers to AMD's ability to basically turn the GPU entirely off

00:02:39.280 --> 00:02:44.480
when you're not doing anything allowing you to save power when you're idling or

00:02:43.040 --> 00:02:49.120
not doing much on your computer which let's face it a lot of computers do the

00:02:47.120 --> 00:02:53.440
next feature that at the time of filming this video is completely unique to this

00:02:51.280 --> 00:02:57.280
card is true audio which is a programmable dsp right on the graphics

00:02:56.000 --> 00:03:01.599
card for you guys guessed it audio this allows

00:02:59.680 --> 00:03:05.040
the sound engineers that work on your favorite games to offload that

00:03:03.599 --> 00:03:10.080
processing that would normally be done on the CPU and have it done instead on

00:03:08.239 --> 00:03:14.480
the GPU itself this means that you're going to be able to get much more

00:03:11.519 --> 00:03:19.840
realistic audio effects so in particular convolution reverb is a technique that

00:03:17.280 --> 00:03:24.080
uses what you'd kind of consider to be an image of a room and how sound should

00:03:22.159 --> 00:03:29.040
behave in it so the materials it's made of the shape so that when you walk into

00:03:26.480 --> 00:03:32.720
a dungeon it'll echo and the drips of water will bounce around off the walls

00:03:30.879 --> 00:03:36.239
versus when you walk out it's a much more open feeling experience this has

00:03:34.400 --> 00:03:40.239
been implemented in thief i saw a demo of it and it actually works it's the

00:03:38.480 --> 00:03:46.080
first time we've seen any kind of real advancements in hardware sound for games

00:03:43.040 --> 00:03:48.239
since eax so that's very very exciting

00:03:46.080 --> 00:03:52.000
but right now just this card although guys stay tuned very soon there will be

00:03:49.840 --> 00:03:56.879
at least another card or two with this feature implemented next up is mantle

00:03:54.640 --> 00:04:02.640
this is really to me the big news about the r7 and r9 series of cards because

00:03:59.760 --> 00:04:06.080
they're directx 11.2 cards which is an API so they're also compatible with

00:04:04.239 --> 00:04:12.080
opengl and oh wait but mantle is now a third

00:04:09.200 --> 00:04:16.479
API that AMD wants developers using they want to leverage the experience that

00:04:13.920 --> 00:04:22.000
developers have developing games on the latest generation of consoles the ps4

00:04:18.560 --> 00:04:25.120
and the xbox one to use that same type

00:04:22.000 --> 00:04:28.560
of approach to program for desktop pc

00:04:25.120 --> 00:04:31.600
gpus so what mantle does is it bypasses

00:04:28.560 --> 00:04:33.280
directx and opengl completely forgets

00:04:31.600 --> 00:04:37.520
about those and is actually a completely new way that the game engine can

00:04:34.800 --> 00:04:42.639
interact almost directly with the card at a much lower level this should turn

00:04:40.240 --> 00:04:46.479
into some very tangible performance improvements and i'm extremely excited

00:04:44.479 --> 00:04:50.960
to see where this technology goes but there are some caveats because obviously

00:04:48.800 --> 00:04:55.120
if we have game developers they you know they have to support directx a lot of

00:04:52.800 --> 00:04:58.000
them support opengl and then now mantle and then what if NVIDIA had their own

00:04:56.560 --> 00:05:01.199
and then what if Intel had their own for onboard graphics and all of a sudden

00:04:59.759 --> 00:05:05.840
we've put a lot of extra load on the game devs well let's hope it doesn't go

00:05:02.800 --> 00:05:07.600
down that path but for now AMD's telling

00:05:05.840 --> 00:05:13.440
us that game devs have been asking them for this and in particular because of

00:05:10.240 --> 00:05:14.320
their presence in every next-gen console

00:05:13.440 --> 00:05:20.320
well it might actually succeed so that's extremely exciting there's a new fan

00:05:18.320 --> 00:05:24.160
profile as well as an updated power tune so the fan profile allows much more

00:05:22.080 --> 00:05:29.120
gradual ramp down and ramp up speeds of the fan so you don't hear that

00:05:27.280 --> 00:05:32.880
when the temperatures are sitting on a threshold where it changes quite

00:05:30.479 --> 00:05:38.240
frequently and power tune now accounts not only for GPU clock speed overall

00:05:35.680 --> 00:05:42.479
board power and power consumption but also temperatures so this is much like

00:05:40.320 --> 00:05:46.400
GPU boost 2.0 where you have a lot more granular control of how the card behaves

00:05:44.479 --> 00:05:50.160
with that said overclocking has been simplified somewhat to the point where

00:05:48.080 --> 00:05:54.400
all you really do now is adjust your maximum clock up and then the card will

00:05:52.320 --> 00:05:58.960
run sort of wherever it can you can make some adjustments to the power limits of

00:05:57.120 --> 00:06:04.479
the boards however the temperature limits come in pretty much set to their

00:06:01.680 --> 00:06:07.840
maximums so the only way to really um you know leverage more overclocking

00:06:06.319 --> 00:06:11.919
other than just turning that slider up is going to be to add better cooling to

00:06:09.759 --> 00:06:14.880
your graphics card the raptor app is something that AMD is talking about a

00:06:13.280 --> 00:06:19.520
fair bit which is a way of connecting with other gamers it's platform agnostic

00:06:17.280 --> 00:06:23.759
it allows you to get rewards for playing and most importantly this is another

00:06:21.680 --> 00:06:27.280
competitor for an NVIDIA technology they've had for a little while the

00:06:24.720 --> 00:06:31.759
GeForce experience it allows you to with one button just say look optimize my

00:06:29.440 --> 00:06:36.160
settings for this game i care more about the appearance of it or i care more

00:06:33.440 --> 00:06:40.400
about the performance of it and it'll just figure out what you want and it

00:06:38.319 --> 00:06:43.440
uses cloud-based data sourcing so it collects anonymous data from everyone

00:06:41.759 --> 00:06:47.280
else running the game as well as the performance they're getting and then

00:06:44.880 --> 00:06:51.520
optimizes your configuration based on other people who have similar hardware

00:06:49.120 --> 00:06:56.160
who are running it acceptably finally guys never settle as always

00:06:54.400 --> 00:06:59.280
games come with your card however stay tuned because never settle is changing

00:06:57.759 --> 00:07:02.639
constantly so you're going to want to check out what your card comes with at

00:07:00.880 --> 00:07:07.120
the time without further ado i'm going to hand this off to slit to tell you

00:07:04.400 --> 00:07:09.840
guys about the performance of the r7 260x

00:07:08.639 --> 00:07:15.199
the charts you're going to see here in a moment are going to be quite general they're going to have all the graphics

00:07:12.800 --> 00:07:21.599
cards that i tested today on them but what you should be focusing on is

00:07:17.280 --> 00:07:23.840
the gtx 650 ti boost and the r7 260 x as

00:07:21.599 --> 00:07:28.160
they are the most comparable cards on that chart now one thing to note is that

00:07:26.240 --> 00:07:34.319
the 650 ti boost has been out for quite a while so it's been being optimized for

00:07:29.680 --> 00:07:36.000
a very long time and the 260x is very

00:07:34.319 --> 00:07:40.560
brand new running a beta driver and has not been being optimized for that long

00:07:38.000 --> 00:07:45.360
so we're likely to see the gap closing up a little bit in the future and

00:07:42.639 --> 00:07:50.319
another thing to note is that all r7 260 x's are two Gigabyte now while if you

00:07:47.919 --> 00:07:54.319
have one monitor that's 1080p or below that may not matter too much but if you

00:07:52.319 --> 00:07:57.840
want to personally prepare yourself for what you might do in the future getting

00:07:56.080 --> 00:08:01.599
more RAM on your card is a good idea because the second you add more monitors

00:07:59.520 --> 00:08:04.879
or go to higher resolutions or just general games in the future

00:08:03.440 --> 00:08:08.400
it'll help a lot to have that extra memory on board now as you guys have

00:08:06.720 --> 00:08:11.759
seen in the chart so far it's actually a pretty close fight but there is a little

00:08:09.840 --> 00:08:15.440
bit of differential there so if you liked the video like the video if you

00:08:13.360 --> 00:08:18.400
disliked the video dislike the video and in the comment section what do you think

00:08:16.879 --> 00:08:24.070
of mantle and what do you think it's going to do to the future of gaming be
