you guys would probably be very surprised to hear how many people ask me if there's an advantage to running AMD Radeon cards on an AMD platform versus 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 started the GPU performance multiplier you know factoring 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 this is 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 Radeon HD 7970 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 the CPU this is an FX 80 140 which is some like weird CPU that doesn't seem to be existing anywhere and I don't know if it's ever even gonna be released but what I've done is I've it at 4 gigahertz so that should be fairly equivalent to something like an 80 150 in terms of performance in most games 4 gigahertz is an easy overclock so just bear that in mind we're gonna be comparing this AMD 8 core at 4 gigahertz to my stock speed 3930k platform and then we're also gonna be comparing this CPU performance with the 7970 to the CPUs performance with the gtx 680 so just bear that in mind and 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 am using all ultra maximum settings other maxing out the anti-aliasing which I've got pegged f4x which for me is a pretty comfortable setting at 1080p I find that reduces most of the jakey's for me personally so since I'm the one doing the video I guess I get to pick things like that 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 be prepared crazy stuffs gonna happen all right guys well results are done so I guess you can kind of hang with me while I while I rearrange the spreadsheet a little bit so I'm just gonna hide some of the less relevant rows and we're just gonna 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 around 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 across there 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 gonna make to things like idle power consumption so grain of salt guys grain of salt 3d mark 11 squares are pretty much not affected this is yeah very very close but we do see a slight perform decrease on the AMD platform over here I see I didn't take temp readings this time around because 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 slower doesn't mean that it will perform any differently in that game as long as you have the the graphical horsepower another thing to bear in mind is that battlefield series frostbite engine is heavily multi-threading aware so the fact that this is 8 cores versus 6 maybe making a difference for it hard to say at this point in time Crysis 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 in the 79 70 The Witcher 2 sees very similar performance I would consider this to be sort of pretty close to margin of error here guys dirt3 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 especially on the 680 and takes a bit of a hit on the 7970 finally Skyrim just falls off a cliff with the bulldozer CPU versus using the 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 we are using more power than the 3930k intel 6 cora 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 scheme II thing with like your red motherboard and you're ready in the performance edition RAM and Radeon 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 here there is no issue pairing up a geforce with an AMD chip or Radeon with an Intel chip thank you for checking out this episode of - tech tips don't forget to subscribe for more unboxings
