the g4 560 might be something of an i3 killer but we still wanted to know just how far the CPU can be pushed before it starts choking GPU performance we're looking for the point of diminishing returns in today's test it's unlikely that someone who buys a $70 CPU would also buy a $500 GPU but that doesn't mean we shouldn't try to better understand how the CPU scales with cards price from 115 to $600 before that this video is brought to you by course there's a new vengeance RGB LED Ram which ships with custom screens ICS for better overclocking performance and stability given that memory is highly relevant for performance with new rise in CPUs now is a good time to do research on high performance kits start with the Vengeance RGB LED kit at the link in the description below the G 4560 is a CPU that we reviewed highly and said that it competes with Intel's own I three lineup for a much cheaper price it tends to be about $70 on retailers and it's clear that an ultra budget targeted CPU like this one which is clearly capable of gaming based on our review would be most likely paired with something like a GTX 950 or an rx 560 or maybe something below those but those are pretty obvious choices given the price and given that everyone knows about where their performance falls what we didn't know is how high end of a GPU can you get to before you are really wasting money not just a little bit starting to hit diminishing returns in waste money but lighting it on fire and completely wasting it so we're testing today from a 1050 Ti and up that includes 1050 Ti 1060 SSC 1070 and 1080 from Nvidia and we've also thrown an Rx 570 from AMD and an rx 580 gaming X the 570 will be interesting to pay attention to because it's a step beyond a 1050 Ti and we've generally recommended the 417 out of 5 seventies over something like a 1050 Ti if the extra money is affordable for you but with the new price reduction 1050 TI's being around 115 with rebates pretty commonly and with the 570 coming out and changing things up a bit it's worth looking at how both of them perform in relation to one another and in relation to the cpu specifically we did not include the 1080 Ti because once you start hitting the 1080 you're really starting to hit the cap and also the five 65 50 and 10 50 are all well within the CPS performance abilities that means that if you run one of those GPUs with the CPU in every game we've looked at the CPU has more in it that it can push if you were to get a better GPS so those are not going to be bottlenecks which means they are not included for testing methodology as always check the links in the description below where we've got the full review testing methods and all the charts in plain text format if you want to check that out with a couple of extra notes but for now let's dive straight into the benchmark starting with GTA 5 starting with GTA 5 we immediately see our point of bottlenecking at the GTX 1080 and gtx 1070 where the to perform effectively identically there well within tested test variants here and the 1080 FTW 1070 SCR both walked around 102 101 FPS average these cards are again equal in performance the GTX 960 SSC runs 96 FPS average so we have some performance degradation making me 1070 and 1080 about 4.9 percent faster that's definitely diminishing returns for buying anything more than a 1060 since the price hike is so big in the performance again it's so small but to further illustrate this we can see that the GTX 1050 Ti scales almost completely to the 1060 or the 1060 run 52 percent faster than a 1050 Ti and RS 580 is also nearing the cutoff points of 100 FPS but it doesn't push quite as hard where it gets there what we learned from this is that anything from a 1060 n down and that would include the 570s 1050 Ti or even its equivalent rx 580 none of those would be sufficiently bottlenecked by the G 4560 in this game the cutoff point is 100 FPS for these settings with this CPU at which point we experienced diminishing returns but that's just one game it's not enough to make a conclusion let's look at total war or Amer next total war we're hammer has a similar cutoff point where we'll start seeing some scaling with the higher end cards but it's to the tune of one to two FPS average 170 gtx 1060 level then beyond scaling from a 1060 to the 1080 is an improvement of just four percent total which is nothing close to what we see in our normal GPU benchmarks on the cpu limitation is removed the GTX 1060 is also significantly keeper so clearly there's no reason you would ever spend that much money to gain 4% FPS but looking at the 1070 1080 and 1060 we see that they are all functionally equal in this game when paired with the g4 560 the RX 580 is not too distant from this group with its 97 FPS average as previously you could purchase anything from a gtx 1060 or rx 580 and downward and end up just fine or more or less at the limit of what the CPU can do the 1060 seems to be about the cutoff point for this game Sniper Elite is the odd man out for the games DirectX 12 native integration and asynchronous compute functions permit the CPU draw a call workload to largely shift to the GPU and this instance we see some really interesting results the scale ena goes all the way up to the GTX 1080 surprisingly where we've got a 170 FPS average at 1080p with high settings and that puts the 1080 about 27% ahead of the gtx 1070 which really isn't all that bad 10:7 is at 134 FPS average and is therefore about 38.5% of the GTX 960 SSC the RX 580 gaming X runs a 109 FPS average but none of these cards are at the limit of what the CPU can handle because as we can see with the 1080 we're really doing just fine with all of them would strongly recommend not basing purchases on this one game though as this is an extremely rare case in the gaming world now especially when we look at things like its SLI or crossfire scale in which are nearly 100% not many people would consider coupling a 45 60 with a 1080 to begin with but it's worth noting that you shouldn't adjust because of this one game let's look at another DirectX 12 title to see what happens there now we're looking at Ash's escalation the GPU benchmarks specifically which may as well be a synthetic test at this point escalation has the gtx 1080 1072 m 60 RX 580 and rx 570 all performing mostly the same with no difference visible until the gtx 750ti which isn't that much behind but it's really the only one that starts to show a difference the cutoff point seems to me about the RX 570 here and we look at the ashes of the singularity CPU benchmark just to kind of prove a point we can see that the CPU performance is the same and all these tasks regardless of which GPU is used because it is properly a CPU benchmark more akin to what a synthetic benchmark would do than what most games would do battlefield one is next with DirectX 11 and 1080p ultra settings battlefield one post some scaling for the 1080 from the 1070 though it's limited to 11% we'd only see more than this when not CPU limited ie when testing with the 7700 K and although the 1080 post improvement is well into the point of diminishing returns the GTX 1070 holds an improvement of 18% over the GTX 960 SSC or 12.5 percent over the rx 580 scaling seems to choke past a GTX 970 let's game although you get better value with the 580 or a 1060 based on performance and the other games Ghost Recon wildlands is another title where brute force gets us some extra framerate but we start encountering limited gains once again at the top-end the GTX 1080 runs about nine point seven percent faster than the 1070 in this game which in turn runs 15% faster than the 10 SEC the SSC we experienced a weird reproducible issue with Ghost Recon wildlands where the rx 580 is producing results that very pretty heavily after the first pass even this isn't something we saw when testing with the i7 7700 K and this GPU and only encountered with the 45 60 here's a look at some of the numbers in order of test execution top to bottom we did two complete runs each with four test passes or more and each after system reboot the first pass spikes second pass drags and then things begin to level out after that though with higher M CPUs we were seeing that very steady reliable performance we're not sure what's causing this on the 45 60 or if it's some kind of driver difference or Windows difference between the two test systems but we also observed interesting performance and watchdogs - with the same card and we're awaiting further thoughts from our industry contacts including those at AMD and NVIDIA to hopefully better understand what's going on with both watchdogs - and Ghost Recon wildlands either way it's looking like the cutoff point is about the same as in some of the other games we've tested as far as when the GPU becomes bottlenecks by the CPU so depend on which game you're looking at there's no scaling us on them and there's massive scaling and Sniper Elite for which it makes sense Sniper Elite 4 is one of the only really well-built DX 12 or low-level API titles at all with its name maybe doom and it uses async compute it's generally not that intensive of a game to begin with and so it's performing well but that is what you would call an outlier that's about to minimize its performance but you should not base a GPU purchase with a $70 CPU on that one game unless perhaps it is the only game you will ever play as far as other games GTA 5 total war Warhammer and the ashes of the singularity show basically no scaling whatsoever between a 1080 and a 1070 and the cutoff point really if you want to get the best value seems to be about a 1060 FF very high-end though it's be fair if you're spending $70 on the CPU you'll probably be just fine with something that's a more realistic purchase for you which might be something in the range of a 1050 Ti of course there are plenty of neighboring options as well and if you've got more or less money the 570s fine the 1050 or the 560 are fine as well 1050 G is plainly in the middle but either way once you had a GTX 1060 it's hard to justify going beyond that even if you wanted to upgrade the CPU later now that said the GPUs and the CP is do well enough together in these titles all of them that if you wanted to buy a 45 60 now for some reason and upgrade to something like a 7700 K later you could do it and still get a lot of your performance out of those cards just expect that it will start choking at some point once you're 10 60 and beyond but overall hopefully this will help someone out there with a PC build determine how high on they should go with the GPUs scaling is fairly clean from even the 1050 Ti to the 572 the 518 1060 just it
