now this video is going to be a bit of a look at sli scaling on the gtx 550 ti
0:06
now sli has been a big story for NVIDIA since they first released it with the
0:11
6800 series however not every
0:15
not every card necessarily makes sense to run an sli so
0:19
i've always been of the mind that if there is
0:24
a better card than the one that you have
0:27
that is as good as two of the one that you have
0:31
running in sli you're probably usually better off to go with the single more
0:36
powerful card versus the two slower
0:39
weaker cards running in sli so i wanted
0:42
to take a quick snapshot of some directx 11 titles so the ones that i've gone
0:46
with are hawks 2 lost planet 2 and metro 2033 and
0:51
i compared 4 different scenarios so i compared a single gtx 550 ti cyclone 2
0:58
so that is a slightly overclocked card i compared that running an sli with a
1:04
gtx 550 ti reference card
1:07
i compared a gtx 560 twin frozen two so
1:11
once again this is a slightly overclocked card but since neither of
1:14
these carry a price premium over the reference cards i see no reason to
1:18
necessarily bench with reference cards and the last one that i included was the
1:22
gtx 570. so the reason i've gone this
1:25
route is that the cost of a single 550 ti
1:30
is well significantly lower than anything
1:33
else on the table however the cost of two of them together
1:38
actually lands somewhere in between a 560
1:42
and a 570 so that's why i wanted to test
1:45
the single gpus that are available on either side of the price bracket of
1:50
this dual GPU solution now the upgrading guys will say well yeah but what if i
1:55
wanted to upgrade to one later then my response would be well then what you
1:58
really should have done was saved a couple extra bucks to buy something else
2:02
uh in the first place if you need more performance then buy something with more
2:06
performance so here we go why don't we have a look at the benchmarks that i was able to run
2:11
here and we'll start with hawks too so in hawks 2 you can see that the gtx 550
2:16
ti at about 85 frames per second actually scales incredibly well in this
2:22
particular game so that's like uh 90 percent scaling or so and
2:28
actually performs right exactly where it's supposed to be in between the 560
2:33
ti and the 570. however even this is an
2:37
ideal scenario an ideal scenario has the 550 ti performing about where it should
2:43
in terms of the pricing of this solution
2:46
so you're going to see that the problem with sli is that it doesn't always scale
2:50
in an ideal fashion so right here our 550 performs about where it should with
2:55
respect to a 560 and even a 570 but the
2:58
sli solution while costing more than a 560
3:03
and consuming more power than a single 560 actually doesn't even perform as
3:08
well and remember the 550 ti sli
3:11
solution is about as expensive as in between these two so really it should be
3:16
right in between them it should be around 50 FPS but it's uh it's about 10
3:21
to 12 percent slower than that in lost planet 2. and now let's have a look at
3:25
the last one that i ran here which is a metro 2033 benchmark so here i've got it
3:30
running at normal quality with tessellation on and zero times
3:34
anti-aliasing all of these benchmarks are at 1920x1200 by the way so you can
3:39
see the 550 ti is right here 550 ti sli
3:43
really doesn't scale that well compared to where it should be which is around 90
3:47
FPS so once again we're looking at like a 20 performance delta
3:53
difference between where it should be to justify the price versus where it
3:58
is when it doesn't scale quite as well as
4:01
it could so i basically the conclusion
4:04
of this is that the 550 ti if you do buy
4:08
one and you find yourself needing some more performance yes you can get
4:12
additional performance and you can go from what i would consider basic
4:15
playable to very very playable in a demanding game like metro 2033 at full
4:20
hd resolution however if you know you need the performance
4:24
you're going to be playing demanding games at hd resolution then just get a
4:29
560 ti do yourself a favor and buy the right card in the first place because
4:34
even though once in a while and this is sort of the
4:38
exception not the rule the 550 ti sli
4:42
setup will outperform a 560 ti you're gonna get a more consistent overall
4:46
experience with a single more powerful card versus two
4:51
more entry level cards running in tandem
