guys it's finally time I've got my hands on all three of Intel's new caseview processors the i7 7700 K the i5 7600 K and you're hearing it right the i3 7350 K we finally have a case q i3 processor what is it worth buying I don't know let's find out I always have a hard time at doing CPU benchmarks and the reason being is everyone's use case is a bit different and it's really hard to apply any sort of across-the-board testing methodology that is going to apply to everybody so instead what I've decided to do here is kind of utilize the common thread through most people who watch my channel and that being gaming and a little bit of overclocking yeah their case Q processors if I didn't overclock these even a little bit it would really did get negate the purpose of getting case Q in the beginning so what I've done to try and give us the best apples to apples comparison crop across all three of these CPUs as I'm running them at 4.7 gigahertz that's a 500 megahertz overclock to the turbo clock to both the i7 and the i3 and interestingly enough a 700 megahertz overclock to the boost clock of the i-5 for some reason the i-5 has a turbo clock of 3.8 where the other two have a turbo clock is a 4.2 I don't understand that which is really interesting I don't know I don't know why they did that but anyway I've locked all three of them at 4.7 gigahertz to give us the best direct comparison between these three as we possibly can now the rest of my testing system is a z2 70 asrock gaming k-6 fatality motherboard 16 gigabytes of G skills try it at Z ddr4 at 2666 a HyperX savage 960 SSD making sure we're feeding the data fast enough to the CPU and of course a MSI GTX 1080 gaming X GPU the reason why I chose that was I wanted to see how much drop-off there is on the i-5 in the i3 versus the i7 I mean everyone wishes they can have an i7 and a 1080 but the question is is there bottlenecking happening on the lower end cpus and how does that translate to a gaming experience the games I chose are kind of a mash-up of different dx12 games from dx11 games synthetics things like Cinebench I kind of just tried to randomly pick things that I thought would test these in different types of sin areas again this is it's not easy to do these types of benchmarks and have it applied to everybody so with all that crap out of the way let's go ahead and just dive right into it I know you guys are dying to hear the numbers you don't want to hear anything else I have to say so let's do it Cinnabon should be no surprise this is a CPU benchmark utility too obviously we're going to see a huge fall-off between the three so as you can see you are getting a little bit less than half the performance of an i7 with the i3 if we use benchmark as kind of a direct comparison space line but we all know that that's not going to account for all of the uses out there so what about games well let's go and start here with dirt rally dirt rally is one of those games that can hammer your CPU if it's not up to the test it's kind of like once you go over a certain threshold of CPU performance then you you kind of get all the FPS but if you don't have enough that it falls on the face really hard we learned that when I did that super low-end 375 dollar build with the Athlon but the i7 and dirt rally gave us 173 FPS the i-5 gave us interestingly enough 174 FPS 1 FPS more and the i3 gave us 163 FPS so although we had quite a bit less computing power on the i3 than the i7 we were only dropping about 10 FPS compared to the i7 that's really not bad considering the 10 80s throwing a lot of frames at the CPU to have to handle I expected a bigger drop off to be honest now rise of the Tomb Raider a dx12 title one that had some rocky issues when it launched but it's been patched and has been getting better with its dx12 optimization we got 835 FPS on the i7 134 on the i5 and 134 on the i3 so pretty much identical performance across the board obviously that's due to DX 12 which is huge this is why we need to see more game developers doing good optimization for DX 12 because it really does make up for lower end hardware Metro last light is a dx11 title and has been known to bring gaming systems to its knees it's one of the reasons why I leave Metro in my testing lineup because I have seen it literally bring systems begging for mercy the i7 gave us 169 average FPS the i-5 156 in the i3 131 so 37 fps prints between the i3 and the i7 131 it's amazing but that's quite a bit of drop-off compared to the i7 so it means even with hyper-threading and the system effectively looking at it like a quad-core processor there's even a bit of difference compared to physical cores versus the for logical cores found in the i3 in the i-5 GTA 5 is another title that is dx11 and has a huge sandbox Open roaming world if you will that can really hammer your CPU is it is a CPU intensive as it is GPU intensive so building a system for GTA 5 you have to have the best you can get in both worlds now the i7 gave us 155 SPF no surprise there now that is in game by the way that is not the little benchmarking track this is the first mission you do with Franklin where your repoing the cars and you're racing through town it's fast-paced lots of stuff happening so it's a very good test and it's a consistent test which is why I like doing it that way and not using the built-in bench mark but 155 on the i7 138 on the i5 and 116 on the the i3 at 39 FPS drop-offs across the board that's quite a bit more target I want to say that's about 25 percent my math could be wrong I'll make a little pop up if I'm way off but anyway that's quite a bit of drop-off obviously we can see we can see that the 1080 is being affected by v8 v i3 quite a bit on that one now let's talk about time spot I put time spy in here because it is a dx12 benchmark which is going to be able to show us not only a cpu score a GPU score but at a combined score so we can get a bigger picture of what's happening across the board with all three of these CPUs now if you compare all of these scores across the board something interesting happens that I can't quite explain the GPU score went up as the processor went down I can't explain why we got a faster score on the i3 than all three of them and a faster score on the i-5 than the i7 now the combined was obviously higher across the board as a CPU went up because you know he has a CPU test in there that it does as well which the i3 kind of falls in space all the way down to 10 FPS like I said they're running the exact same speed for 0.7 across the board the exact same systems just swapped in the CPUs and did the exact same test again with all the same settings so really interesting on that one now I know this video wasn't specifically about the 73 50k but I think it's important to mention something here even though it has hyper-threading and it's unlocked and you can overclock it on the test that takes CPU performance into account you can see that the i3 with its four logical cores is not equal to an i5 with 4 physical cores and no hyper-threading so it's really difficult for me to recommend this I 373 50 K even though it's got all of its enthusiast features on there when for approximately the same price you can get an i5 7500 which is a lock CPU it's not a KC PU it still allows some B clock overclocking but it's approximately the same price and you're going to get better performance out of the 7500 than you would a 73 50 K in fact something I need to do in another video here is compare the i3 73 50k to an AMD 8350 because again they're the same price and we want to see if we get direct comparisons now obviously you get some of the latest features on kb lake requires Windows 10 to actually take advantage of most of those features but that's a topic for another video so although performed very very well I still have a hard time recommending it especially if we're talking about budget builders because the Pentium series was something that was amazing it was under a hundred bucks dual cores obviously fell on its face not long after it was launched it just wasn't powerful enough but the new Pentiums also have hyper threading it included on them in this generation with kb lake and they are nowhere near the hundred and eighty dollars that this I 3 is retailing at so it's again I it's one those where I feel like Intel's trying and I think they might feel like AMD's on their heels so you gotta do something but the question is are they giving us too little too much too little difference at too much of a cost that's where you guys come in sound off in the comments watch other kb lake videos and take all of that information you're going to learn and then for my opinion not just mine this is one test and just some games and stuff here on this so there's a lot of use case scenarios for these CPUs so try to do the best you can to formulate your own opinion using a lot of different videos and sources and website and then tell me what you think sound off in the comments or hit me up on Twitter guys thanks for watching also to you if these are available on Amazon I will link them down below save the timing of these is still kind of hard to your hands on it I think micro Center might have some but I digress it's not that important thanks for watching guys there's always I'll see you in the next video
