you guys would probably be very surprised to hear how many people ask me
if there's an advantage to running AMD radon cards on an AMD platform versus uh
running a GeForce card on an AMD platform and I can tell you guys now
before I actually finish running the benchmarks no there is not you the CPU
performance times sort of the GPU performance
multiplier you know factor in any bottlenecking that's occurring where one
of them is not feeding the other quickly enough that's pretty much how perform
how much performance you get you know PCI Express this is you know a this is a
an industry standard and CPU performance
is CPU performance and GPU performance is GPU performance however for those of
you out here there who are running AMD based systems I've decided to do some
bulldozer benchmarks with the GTX 680
versus the radon hd7970 so what I want
to achieve in all of this is to give the AMD guys a good idea of how these two
cards will perform now I am see I don't know what to tell you
guys about this CPU this is an fx 8140 which is some like weird CPU that
doesn't seem to be existing anywhere and
I don't know if it's ever even going to be released but what I've done is I've clocked it at 4 GHz so that should be
fairly equivalent to something like an8 50 in terms of performance in most games
4 GHz is an easy overclock so just bear that in mind we're going to be comparing
this AMD 8 core at 4 GHz to my stock
speed 3930k platform and then we're also going
to be comparing this CPU performance with the 7970 to this CPU's performance
with the GTX 680 so just bear that in mind in all of my results and stay tuned
here guys just so you guys know if you didn't
watch my regular performance review with my 3930k platform on LGA 2011 I using
all Ultra maximum settings other than maxing out the anti-aliasing which I've
got pegged at 4X which for me is a pretty comfortable setting at 1080p I
find that reduces most of the jaggies for me personally so since I'm the one
doing the video I guess I get to pick things like that uh so yeah we're at
1080p we're at Ultra or high or whatever
they want to call it settings across the board on all of these games
and here I go so now I'm testing the GTX 680 on this same
platform and uh be prepared crazy stuff's going to
happen all right guys well results are done so I guess you can kind of hang
with me while I uh while I rearranged the spreadsheet a little bit so I'm just
going to hide some of the less relevant rows and we're just going to stay
focused on bulldozer 680 versus
7970 and then we're also going
to pair all of these down to just the
680 and the 7970 on the 3930k platform so these are
using all of the same testing methodologies other than changing the
CPU and changing the RAM so the 3930k
has 16 gigs of RAM and this one has only 8 gigs of RAM although I really can't
imagine that'll make a difference in anything other than power consumption so
the 3930k should be at somewhat of a disadvantage because it does have more
RAM on board
it other than that I think we're pretty darn near identical here this is a
Crosshair 5 formula and never mentioned that before from ASUS and I think that's
that's that's pretty much it so here we go so idle power is pretty darn close I
would say this is within margin of error for both of these systems so they're
yeah they're very close that way and once again I can't say necessarily that
my results are you know I should put like quotes here yeah it's an fx
8150 because this is a 95 watt TDP CPU
so I don't know how much of a difference that's going to make to things like idle power consumption so grain of salt guys
grain of salt 3D Mark 11 scores are pretty much not affected this is yeah
very very close but we do see a slight
performance decrease on the AMD platform over here I see I didn't take temp
readings this time around cuz this is just card temperatures I don't really care about that the second time around
for Battlefield 3 you can see performance is pretty near identical
across the two platforms so in very graphically demanding games you can
often encounter scenarios where just because the CPU is slower doesn't mean
that it will perform any differently in that game as long as you have the uh the
graphical horsepower um another thing to bear in mind is that Battlefield 3's
frostbite engine is heavily multi-threading aware so the fact that
this is eight cores versus six may be making a difference for it hard to say
at this point in time crisis 2 we see a fairly significant drop in performance
going from the 3930k to the FX 8150 we
see about 10% and this is consistent on
both the GTX 680 and the 7970 The
Witcher 2 sees very similar performance I would consider this to be sort of
pretty close to margin of error here guys Dirt 3 uh sees a significant
performance drop on both the 680 and the 7970 moving to the other platform
although the 680 takes a bigger hit than the 7970 for some reason Batman Arkham
City is pretty darn close um especially
on the 680 and takes a bit of a hit on the 7970 finally skyum just falls off a
cliff with the bulldozer CPU versus using the uh 3930k so you can see this
is just a disaster overall power consumption is fairly
you know well higher on the AMD platform
pretty much across the board so you can see that it must be somewhere in the CPU
or the motherboard probably the CPU given that bulldozer is a bit of a power
hog uh we are using more power than the 3930k Intel's 6 core unlocked processor
on the LGA 2011 platform and I think that pretty much
wraps it up so in conclusion no there's
no real advantage to pairing this with with this other than that you get like
this wicked like matching color schemy thing going on with like your red
motherboard and your red AMD performance Edition RAM and Ron graphics card I mean
that's cool that's fine and that is a perfectly legitimate reason if you ask
me to you know buy one component over another I'm totally shallow like that
but in terms of technical practical reasons you're there is no issue pairing
up a GeForce with an AMD chip or a radon
with an Intel chip thank you for checking out this episode of lus tech tips don't forget to subscribe for more
