hmm it's the perfect CPU for this build ooh this looks pretty good now I just need a graphics card to pair it with right mmm well this looks to Pinner this is probably gonna bottleneck my CPU but then this huh this is probably over the top it might like destroy it just to be in close proximity to it but I mean how do you keep from bottlenecking your CPU with your GPU and then do you have to worry about picking the right CPU for the GPU can it work both ways what is a balanced build even look like these days good thing we've got all the tools to find out when I say bottleneck what comes to your mind is it super laggy unplayable frame rates and games is it waiting five minutes just to load windows is it the neck of a bottle whatever your exact experience with bottle necks is they all have one thing in common like a five-lane highway merging before a single lane tunnel one aspect of your computer system will be holding back another one keeping it from reaching its full performance potential so bottlenecking has become one of the most common fears among new pc builders I mean after all no one likes wasting money so are these concerns legit or has bottlenecking become some sort of boogeyman for system builders to deter new users from configuring their own we were actually inspired to make this video by the incredible bottlenecking that we experienced when we tried to game on this right here a 64 cores Xeon Phi system but that was obviously an unrealistic scenario I mean this CPU is made up of 64 like crappy atom processors so today's investigation will test just how badly we can bottleneck a more normal system built from actual desktop components so in front of me here is a lower end current gen CPU a popular but pretty obsolete CPU from 2013 and a high end current generation processor we're gonna start then with the most basic of our graphics cards a gtx 1030 this will help us establish a baseline now I'm actually expecting similar performance in games going all the way from a mid tier processor from five years ago all the way up to the brand-new one that would indicate a GPU bottleneck where it's holding back our better CPU and success I guess because we're basically even across the board surprisingly csgo actually runs really well on this card averaging over a hundred and twenty FPS for all of our benches but what's less surprising is the way that in a gaming workload an underpowered graphics card will perform its best pretty much regardless of which CPU it gets paired with so you heard it here first folks a processor upgrade will do nothing for your gaming experience if your GPU can't keep up with that said 3d creation software blender reveals a difference between our platforms demonstrating that whether a system is bottlenecked or not is heavily dependent on the type of work you plan to do on it now then let's retest everything with a gtx 1060 and see how the situation changes right away we're greeted with oh good a difference so the core i7 pulls way ahead in Assassin's Creed origins and csgo and 3dmark confirms this data with a much nicer spread between our platforms which means then that our more powerful processors are getting to stretch their legs a little more because they're not being held back to the same degree but wait it appears as though the gtx 1060 is still the bottleneck for deus ex and far cry 5 this is where our second lesson about bottlenecks comes in it can even be dependent on the individual piece of software with some games favoring faster CPUs and others needing more GPU horsepower in order to look their best coming back around then to our non-gaming tests the results confirmed that productivity still likes a fast CPU to keep the GPU fed ok then so that's probably quite enough of these blue-collar GPUs where the devil Titan V James James is running something on the Titan V right now so we're going to use this Titan V box this gtx 1070 and this gold sharpie marker to create a reasonable facsimile of a titan v here we're expecting some pretty different results and yes we have finally broken the GPU bottleneck on deus ex and our Rison 3 is definitely beating out the FX 6350 for the first time in far cry 5 showing us what an optimized title can do unfortunately blender still doesn't run on the Titan V so we're just left with v-ray which doesn't scale bringing us to our last test scenario dropping our monitors resolution down to 1280 x 1024 on that very same Titan v test platform and oh what's this interesting even with a Titan V we're back to CPU bottlenecking ah yes the final lesson is that bottlenecks will also appear and disappear depending on the settings that you're using in your program lower resolution gaming is easier on the graphics card but actually doesn't ease the CPUs job to nearly the same degree and higher resolution gaming is harder on the graphics card but since that drives the framerate slower the CPU doesn't end up having to work as hard so if your gaming system was severely CPU bottlenecked you actually might be able to upgrade your monitor and play at a higher resolution without losing any fps go figure so really the main takeaway here is that there is no way to avoid bottlenecks altogether think about it a theoretical system with no bottlenecks would have unlimited performance in every workload because nothing would be a limiting factor obviously that's ridiculous something is always going to hold you back and you can't get paralyzed by the bottleneck boogieman as you've seen here as long as you apply some common sense to your config and avoid pairing 30-dollar CPUs with $3,000 graphics cards you should be just fine and you can always ask for advice like maybe over on the Linus tech tips for them about where the bottleneck might be in your system and how severe it might be just make sure to provide some information about what you expect to use your PC for and what kind of settings you expect to run at or as you can see it's gonna be pretty hard to help you so thanks for watching guys if this video sucked you know what to do but if it was awesome get subscribed hit that like button or check out the

you can get bottleneck advice
