Extreme Ryzen Gaming Performance: GTX 1080 Ti SLI @ 4K

2017-04-18
welcome back to harbor unbox for another benchmark video this time we're looking at geforce gtx 980ti sli performance on the horizon 7 1800 X Rosen 5 1600 X and core i7 7700 K processors now the reason I'm taking two of the fastest gaming graphics cards available right now and comparing their sli performance on these processes is because I can actually the idea for such a comparison was as it often is conceived by the viewers back when the horizon 7 Series was first introduced and there was all that controversy over testing performance at the 4k resolution a few cheeky viewers suggested that I give in and do the same but with a pair of Pascal Titan X graphics cards I thought that was an interesting idea and I had planned to check it out quite a few weeks ago but of course as is often the case something else popped up that was a bit more time-sensitive even right now I have a heap of different projects on the go but with the recent arrival of Rison 5 I thought why not give the idea ago this test was also a lot less interesting before the GTX 1080 TI was released previously too-tight next big P graphics cards wouldn't set you back 2400 us if you're going to blow that kind of money you might as well just buy a core i7 69 50 X however now we have the wallet-friendly GT X 1080 Ti at just $700 us just $700 us guys get yours today how why not get 2 for a sweet $1400 SLI setup next you're going to want to know do you go Rison or cabe you like good question let's go find out all testing has been conducted in the past few days using the latest Nvidia display driver 380 1.65 and an up-to-date version of windows 10 - the creators update which caused a lot of games that we test with to crash the 1800 X and 1600 X have been overclocked to 4 gigahertz and although we did use the flagship 8.6 core models the same performance can be achieved with the 1700 X 1700 and 1600 for example the 7700 K has been cranked up to four point eight gigahertz which is an easily achievable overclock for this processor in total eight games were tested using a single G AET I along with SLI configuration since we are using nvidia gpus we stuck with DirectX 11 testing to avoid the issue Rison seems to have with nvidia gpus using DirectX 12 right now right then on to the benchmarks first up we have Deus Ex mankind divided and here we see using a single GTX 1080p our graphics card at 4k provides similar performance across all three CPUs tested if we look at the sli results we start to see some variation in performance the 7700 K provided the best performance here though it is clocked 20% higher thanks to Kaiba lakes ability to clock higher the 1% time results provided the greatest variance between the Rison processes the 1800 X here was 13% faster than the 1600 X while the 1800 X and 7700 K were very similar for this metric moving to the average frame rate we see that 7700 K was 5% faster but this isn't a significant margin though it did mean that overall the KB Lake cpu what's faster Far Cry primal is the game that I have previously dumped from our battery r games we use for measuring CPU performance but I brought it back to see if in this test SLI changed anything as you can see here SLI doesn't help rise and with the second geforce gtx 980ti helping out the frame time performance goes unchanged for the rise in cpus while the average is boosted by just 25% meanwhile the 77 Erik ALS for 67% more frames when using SLI though here the 0.1% data is less impressive using a single GTX 1080i at 4k again we see that all three CPUs provided very similar performance in fact this time they delivered identical performance adding a second GTX 10 ADC I increased horizons performance by 30% and the 7700 k's average frame rate by 46% that says looking at the frame time data there is virtually no difference in performance between the three CPUs tested the Mass Effect Andromeda results are interesting using a single gtx 1080i the 77 her okay was just 5% faster but with 210 ATT is in sli the 77 okay is now 19 % faster at least when comparing the average frame rate we know that at 4k using a single GT X 1080 o we our GPU bound and this is likely still the case with 210 attrs from previous tests we know that a 1080p the rising CPUs can push the 1080 tio2 an average of over 120 FPS so I'm not sure why the 1800 X and 1600 X struggles so much here again this is probably down to a display driver issue The Witcher 3 Wild Hunt is the oldest game we test with and here we see mostly consistent scaling by adding a second gtx 1080i we see the 7700 k performance is boosted by 70% while the rising sea views were boosted by 65% that said the 7700 K did a much better job when looking at the frame time data as we've seen for most of the games tested when using a single gtx 980ti the performance was much the same for all three cpus moving the sli results and here we see the 7700 K starts to pull ahead though given its clock speed advantage the fact that it was just 14 percent faster when comparing the average frame rate bodes quite well for Rison I should note that total war Warhammer has been recently updated to improve horizons performance so this explains why the numbers look so good here now the overwatch scaling is very odd indeed as we find adding a second gtx 1080i boost performance by more than 100 percent for all three cpus tested I should note though that this isn't true for the point 1 percent and 1 percent results logically it doesn't seem possible for performance to be boosted by more than 100% when adding a second GPU but this is a strange phenomenon that has been seen by others as well what's more interesting is that the scaling is even more extreme on the rise and cpus whereas the 1800 x was 25% slow on the 77 or ok with a single GTX 10 atti adding a second reduce the margin to just 17 percent it's certainly worth noting that the 1800 X offered better 0.1 percent and 1 percent performance last but certainly not least we have battlefield 1 these are perhaps the most interesting results as the 7700 K went from being the fastest CPU tested with a single GTX to the GI graphics card to the slowest with a pair of them looking at the average frame rate the 7,700 case are a mere 20 percent performance boost when employing sli meanwhile the 1800s received a 34 percent performance boost that's still pretty miserable scaling to be honest but it was surprising the fine rise and pulling ahead in this title so there you have it a mixed batch of results that tell us investing in two GPUs is generally a bad idea with such mixed results it really is difficult to draw any solo conclusions from the data really the only concrete conclusion here is that SLI scaling is all over the place even in games that support the technology if we average the results across the eight games tested this is what we find on average of the 7700 K allowed for an average frames per second boost of 65 percent when using SL live this margin though was reduced to 55 percent when using the 1800 X in either situation no pay 100% more which in this case is $700 us to extract nowhere near 100% more performance in most games it's not exactly a wise investment still if you were to pick a graphics card to use SLI with the GTX 10 atti makes the most sense I'm personally not a fan of SLI at all but have noted in the past that if you are going to use multi GPU technology it should be reserved for the most extreme GPUs it's interesting to note that while the 7700 K was on average 14% fast in the 1800 X when comparing the average FPS it was just 8% faster for the 1% time and 2% faster for the point 1% time in games where SLI scaled well such as overwatch and The Witcher 3 we see that Rison was able to do with a similar scaling performance to that of the 7700 K the same is also likely true for that our updated total war Warhammer it's just that the 7700 K was GPU bound with a single gtx 1080i the fact that Verizon was just 12% slower on warhammer using the 1080 Ti SLI configuration is actually a very impressive result given it is clocked at 17 percent lower of course there's nothing AMD can do about the clock speed deficit for now Rison is inferior to the smaller table 8 processors when it comes to clock speeds and until games require more than four cores this will hurt them in the short term of course we have already seen under more realistic conditions when using something like the gtx 1070 or fury x rising is even more competitive as these mid-range to high-end GPUs usually provide GPU limited scenarios I do ever hate more testing coming up that looks into this and so far the results do look very interesting getting back to this video though I had planned to test around a dozen CPU demanding titles that was until I discovered that most of them don't support SLI games such as f1 2016 Gears of War 4 hitman and mafia 3 were all dropped due to their lack of SLI support there were plenty of others but I'm not going to waste time rattling off dozens of games of course there were other titles that did support SLI which could have been included but they were mostly GPU bound and probably wouldn't have had as much value to the CPU comparison after a few of you guys planted the idea in my head this is a test that I became quite keen to do as a really don't plan SLI or crossfire that much and well now having completed the testing I remember why in the end the results weren't really interesting or they weren't nearly as interesting as I thought they might be but I hope that satisfies the curiosity of those of you who asked for the test I hope no one from Nvidia is watching this video because I want to keep receiving samples from them but I also want to feed you guys a rubbish so yeah SLI isn't very good to put it nicely actually to be fair multi GPU technology in general sucks on a whole it's wildly inefficient due to a lack of proper support and things really only seem to be getting worse still if you can afford one extreme high-end graphics card and wouldn't blink twice at the prospect of picking up a second then honestly SLI exists because of you so you might as well take the bait okay guys that's all for this one I promise there is a much more relevant test coming later in the week so keep your eyes peeled for that as always thanks for watching I'm your host Steve catch again soon
