Hey Gear Seekers I'm Nick I decided that I wanted to go down the rabbit hole and
explore something that I've never really done before because I've been using and
video GPUs for pretty much the longest time ever you can read articles blog
posts and watch countless YouTube videos about
AMD's crossfire but none of it means anything unless you can see it with your
own eyes if you haven't subscribed yet make sure you hit that button right now
turn on the little bell to receive notifications we upload about four times
a week I think it's like five or six this week yeah so yeah make sure you're
subscribed now the only problem I had with this whole crossfire thing was I
didn't have two identical AMD GPUs and I didn't know whether or not I could still
do crossfire without having two of the exact same GPUs so yeah let's find out
what happened spoiler alert it works you're gonna want to watch to see how it
all works also before you lead stupid comments watch the whole video first
this video is brought to you by cooler Martha and the master case 500 M
featuring interchangeable front panels two giant 200 millimeter addressable RGB
fans for the ultimate airflow and all of the front io you could possibly never
want find out more about their master KH 500 M at the link in the description ok
let's talk about how we're testing this now we're using a similar system to the
one that we used when we tested that asrock phantom gaming iris 580 the
motherboard is the asrock x 470 fatality gaming k4 with the risin 520 616 gigs of
team group t force memory at 3000 megahertz now I threw in the odds rock
phantom gaming RX 580 AG OC that we tested a few weeks ago you can check out
that video right now in the top right hand corner as well and along with that
we chuck in a gigabyte or SRX 584 gig and to be honest I didn't know what to
expect and I thought that it probably wasn't going to work but to my surprise
it worked without me even having to enable anything so yeah I'm guessing
most people in the comments will say that I should have known that it would
work but seriously I never even thought about trying this at all until like
Saturday afternoon you know when you're like tinkering your stuff on a Saturday
and you're like oh I wonder if that will work or well that's basically what
happened anyway we tested the crossfire set up with two titles that I know
should technically scale pretty well with crossfire and yeah I just wanted to
see how big of a difference it would actually make if you could run crossfire
so in every single test the GPUs were running at their factory settings just
keep in mind that both of these cards are factory overclocked as well but only
by a little bit so yeah it doesn't actually add to the performance at much
so yeah let's start off with the rise of the Tomb Raider benchmark we did single
card testing in our a drop phantom gaming rx 580 video so we'll use those
results again so we don't have to retest the first set of tests we did everything
set to high in direct x11 with the single card at 1080p we saw an
average frame rate of 75 frames per second and a maximum frame rate of 116
frames per second in crossfire at 10 we saw an average frame rate of 85
frames per second with a maximum frame rate of 217 frames per second that's a
lot of frames already we're seeing a trend and we're only one testing because
we're using multiple GPUs we decided that we wanted to add some 4k tests in
as well in 4k we saw an average frame rate of 48 frames per second with the
maximum frame rate of 141 frames per second so that's not too bad I mean
that's act playable anyway from tests with some other titles in DirectX 12
with cards above 4 gigs I found that dx12 performance is usually better than
its dx11 counterpart but again it's dependent on the game so yeah we tested
rise of the Tomb Raider in DX 12 as well just to make sure with a single card
with DX 12 in 1080p we saw an average of 75 frames per second with a maximum
frame rate of 117 frames per second that's actually pretty close to the dx11
result with the single card with DX 12 in 4k we saw an average frame rate of 26
frames per second with a maximum frame rate of 40 frames per second now here's
what I actually wasn't expecting with crossfire enabled with DX 12 in 1080p we
saw an average frame rate of 114 frames per second with the maximum frame rate
of 225 frames per second with crossfire enabled with DX 12 in 4k we saw an
average frame rate of 59 frames per second with the maximum frame rate of 94
frames per second that's a pretty solid increase that's almost double the frame
rate and I think it's because crossfire generally scales better in DX well I'd
like to visit this again in another video there cuz I'm still not quite
convinced ok let's get into the quake champion test new was coming come on
it's me everything needs to be tested with quake but the reason isn't just
because I love quite champions it's that it actually
it's quite champions as being optimized for AMD GPUs whereas we know that in
truth it really isn't we did a video about that and you can check that out in
the top right hand corner right now so yeah let's let's let's see the numbers
going off the results of our asrock phantom gaming RX 580 benchmark video we
also know how it should perform with a single card so let's go over those
results to quickly refresh our memory with a single card in 1080p we saw an
average frame rate of 114 frames per second with a maximum frame rate of 134
frames per second with a single card in 4k high with 90 percent extra scaling we
saw an average frame rate of 62 frames per second and a maximum frame rate of
just 73 for a second what do you mean just that's that's pretty good okay now
we upped the ante and did the rest of all of the tests in ultra and not high
because well why not like we've got more video memory we've got more GPUs why not
with crossfire enabled in 1080p ultra we saw an average frame rate of a hundred
and sixteen frames per second with a maximum frame rate of 119 frames per
second now to me that's telling me that the frame rates are actually bit more
stable with crossfire enabling 4k Ultra we saw an average frame rate of 56
frames per second with a maximum frame rate of 61 frames per second now given
that that's not a direct comparison between single card performance you can
get an idea of how well crossfire actually scales we up the texture
quality and the texture scaling and technically it performs better than the
lower setting if you do the math in your head and that makes sense anyway overall
crossfire perform better than I expected it to
in fact it worked without me having to switch AFR modes like I have to do with
SLI although you can do that if you want but I didn't need to we got the best
results in all of the testing from using the default settings so yeah just keep
that in mind if you're thinking about doing a crossfire setup if you right now
should you buy two irx 5 ATS and put them in crossfire instead of vine like
one really good powerful GPU probably not but if you have one rx 580
and wanted to take the power up another level with the out forking up for a
whole like top level GPU it's an option but yeah I probably wouldn't do it
because yeah it's still money that you don't have to spend but it's pretty it's
pretty cool like for testing anyway I'd love to explore this a bit further if
you can think of some titles or benchmarks you think we should use that
scale well with crossfire let me know in the comments and yeah we'll we'll play
around with them I'm actually pretty keen to play around with this a bit more
it was one of those like I am bored on a Saturday afternoon type of videos around
just I just needed to test something anyway I hope you enjoyed this odd
benchmarking video didn't make much sense let us know in the comment section
down below if you think we should make more of these kind of videos also shouts
detect 40 Australia for saying we should do more of these videos in the loss
benchmarking video go and subscribe tonight's channel there is a link in the
description and also on the end card get in 200 subscribers guys he actually
deserves it but Mike actually deserves it the guy makes some really good videos
if you liked this video please like and subscribe if you didn't like this video
you know what to do and yeah tell us what you didn't like about it please
tell us what you didn't like about it once again thanks there very much for
watching I'm Nick with gear seekers you Pig we seek and the only problem with
this crossfire setup is listen how loud this thing is
I think we should more to call it
you
