hey guys welcome back to harbor unboxed today's video is the very first CPU related content for 2070 on the channel and damn do we have a good one for you today yeah I'm definitely over selling this finally after more leaks and a rapidly sinking ship we have the official release of Intel seventh generation desktop processors for this video I have the core i7 7700 K and the core i5 7600 K models on hand and as you might have guessed we will be doing a little benchmarking along with these two processors Intel will be releasing a range of locked core i7 core i5 and core i3 models there is also an unlocked core i3 processor which we've already looked at but we expect the price to be far too high for that one making it a rather pointless product the information I have on hand suggests a bulk buy price of 157 us so you can probably expect it to hit shelves around a hundred and seventy 280 us at that price the skylight core i5 6400 seems like a much better investment and the same is probably true for the core i5 7400 which is suggested to cost around 170 u.s. in 1,000 unit orders when compared to their skylight counterparts it looks like the new KB Lake models are clocked at least 100 megahertz higher well some have as much as a 300 megahertz clock speed advantage the core i7 7700 okay for example runs 200 megahertz higher when compared to the 60s 700 K with a 300 megahertz higher maximum single core turbo boost frequency the other noteworthy changes the upgrade from the HD graphics 532 the 630 version though this does only appear to be a minor upgrade both models run their integrated graphics engine add up to eleven hundred and fifty megahertz the other processor that we have on hand is the core i5 7600 K which comes clocked at 3.8 gigahertz though depending on load Canon clock as high as four point two gigahertz of course like the 7700 K the 7600 K is an unlocked processor and when paired with a Zed 170 or Zi 270 motherboard it can be overclocked to operate at greater frequencies when compared to the 6600 K the new 7600 K model runs 300 megahertz faster so this could afford it up to 8% performance again the updated HD graphics 630 is also being used here and the same integrated graphics can also be found on all of the S series models Intel is sticking with the LGA 1151 socket for this generation so that means KB Lake can be used on existing Intel 100 series motherboards providing their BIOS is up to date however an effort to add a little spice and probably keep board partners happy Intel is releasing their new range of 200 series chipsets the desktop range will comprise of the Z - 7 th - 70 be 250 Q 270 and Q 250 chipsets and thews this will be primarily interested in the Z 270 chipset for a few reasons most notably of which being that it's the only chipset to support overclocking of both the CPU and ddr4 memory the other 270 model being the Q 270 this lacks overclocking support but picks up a number of corporate type features such as Intel vPro technology and Intel standard manageability for example the other corporate focused chipset is the Q 250 and as you have no doubt guessed this is a cut-down version of the Q 270 offering fewer PCIe lanes USB 3 ports and lacks Intel vPro technology the h2 70 chipset naturally fills the same role as last generations H 170 basically H 270 boards will appear to those not buying an unlocked K processor as well as those who only want to run a single graphics card which these days is most of us that said those opting for a core i3 processor a b250 motherboard might be the shot when compared to the H 270 you get far fewer pcie 3.0 lanes at just 12 just 6 USB 3.0 ports 1 M 2 port and a single PCIe x 16 slot frankly this configuration is still ample for an entry-level PC right now we do have quite a few Z 270 and H 270 motherboards on hand and I do plan to take a look at them over the coming weeks but for now let's check out how the Core i5 and core i7 cable 8 processors perform before getting to the games and all that good stuff let's check out the memory bandwidth performance the 7700 K and 7600 K were able to produce the bandwidth of 31 gigabytes per second which is pretty well on par with the skylake processors you can clearly see decent step up from platforms using ddr3 memory now that we are testing with ddr4 exceeding 3,000 megahertz okay so now that we've checked out the memory bandwidth the performance time to check out raw CPU performance using Cinebench r15 here the seventy-seven okay was seven percent faster than the 6700 K while the 7600 K was also seven percent faster than its skylake counterpart these 6600 K as we move through the rest of these tests it's important to keep in mind the cable eight processes are clock to seven percent higher than the skylake models the last synthetic benchmark that we'll be looking at is PC mark eights creative test here the 7700 K scored nine thousand one hundred ninety seven points making it just three percent faster than the 6700k meanwhile the seventy six hundred K scored eight thousand four hundred and fifty seven points making it just two percent faster than the sixty six hundred K the seventy seven okay was just 5% fast and the 6700k when measuring performance using 7-zip built in benchmark more surprisingly was the fact that the 7600 K was just one percent faster than the 6600 K the 7700 K completed the Excel workload in just three point one seconds making it six percent faster than the 6700k though again keep in mind it is clocked around seven percent higher meanwhile the 7600 K was five percent faster than the sixty six under okay before moving on to the games let's check out how long these new CPUs take to complete our Premiere Pro CC workload the seventy-seven arcade took just six hundred and thirty seven seconds which was a ten percent improvement from the 67 okay not bad meanwhile the 7600 K was eight percent faster than the 6600 K okay so now on to the gaming results please be aware that due to the fact will be are testing CPU performance here their settings may seem a bit unrealistic the idea is take load off the GPU and place it on the CPU making that the weakest link this can help identify which cpu allow for more consistent performance under heavy load and likely perform better in the future as games neva tably become more demanding so we are testing at 1080p using a Titan XP in games that are known to use a lot of CPU power games such as over what you'll be used for example and overwatch is actually a really good CPU benchmark it isn't that demanding on the GPU but it can take full advantage of an 8 threaded processor for example especially we're running our bot benchmark first that we have battlefield 1 and here the 77 ok is able to max out the Titan XP reaching 166 FPS on average that said the minimum frame rate was still able to climb and here these 77 our K was 7% faster than the 6700 K again I feel the need to remind you that the 77 our K is also clocked 7% higher the 7600 K was less impressive only delivering around 2% more performance over the 6600 K this time when testing with cities skylines we see a 9% boost in performance for the new 77 ok over the 6700 K when comparing the minimum frame rate meanwhile the 7600 K was just 3% faster than the 6600 K Gears of War 4 is another very heavy CPU user here the new core i7 cable 8 process it was 3% faster than the old skylake process so when comparing the minimum frame rate while these 7600 K was just 2% faster than the 6600 K so pretty weak gains for the cable 8 processes in this title f1 2016 isn't that heavy on the CPU but we included it anyway again the 7700 K was just 3% fast in the 6700 K while the 7600 K was just 4% faster than the 6600 K over watch is limited to a 300 fps cap and the new cable a core i7 along with the 59 60 X had no trouble pushing the Titanic speed to that cap looking at the minimum frame rate the 7700 K was 7% fast and the 67 ok meanwhile the 7600 K was just 2% faster than the 6600 K which was a bit disappointing to find total war Warhammer is the only DirectX 12 game that we've used for testing here we once again see some very mild gains from the higher clocked kb lake processes when compared to sky lake it seems that for cause is ideal for maximum performance in this title as the lower clocked 59 60 X really falls behind losing out too many of them more recently released higher clocked Core i5 processors finally we have the insanely CPU demanding title that is watchdogs to the 77 ok average 91 FPS making it just a single frame faster than the 6700 meanwhile the 7600 K was just 2 FPS faster than the 6600 okay so again yet another disappointing result for KB Lake I've seen a heap of kb lake news over the past few months suggesting that the integrated graphics has been vastly improved upon this was surprising to me as on paper very little looks to have changed comparing the unlocked KB Lake and skylight chips in the Tomb Raider reboot 2012 Sleeping Dogs and rocket League suggests that very little has changed using the normal or medium quality settings in Tomb Raider at 1080p allowed for an average of just 31 fps and that was just 1 FPS faster than the skylight chips rocket League actually played a reasonably well considering with an average of 43 fps using the quality preset which is essentially a medium type quality setting again we are testing at 1080p so no bad result despite only being a few FPS improvement over skylake Sleeping Dogs play with an average of 37 FPS though it did dip down to as low as 24 FPS at times this time the cable 8 processors were on average 3 FPS faster for a 9% performance improvement here we have the total system power consumption figures recorded when running the Excel workload as you can see the cable a process has only consumed a few watts less than the skylight models still given they are clocked roughly 7 percent faster the fact that we are seeing power savings here is decent of course the efficiency improvement isn't amazing but it is the most impressive result we've seen so far using a power bug program like prime95 we see that the 7700 K pushes total system consumption to 148 watts while the 7600 K reach just 126 watts again this made them slightly more efficient than the skylight counterparts so far the 7700 K and 7600 K look ok they've provided small performance boosts over the equivalent skylake processors while consuming a little less power that seems like a win-win and it's pretty well in line with the baby steps that we've come to expect from the modern-day Intel however as I noted a few times we often saw gains of around 7% or less with the cable 8 processors and that's an issue because they're clocked around 7% higher so what happens if we level the playing field well let's find out okay so that's disappointing o'clock four o'clock at 4.5 gigahertz the 6700k and 7700 K deliver virtually the same performance in fact it really is the same performance certainly error of margin stuff the same is also true for the 6600 K and 7600 K clock for clock they're essentially the same processes in terms of performance previously the 7700 K and 7600 K were slightly faster in Gears of War for now in match clock for clock they're indistinguishable from the skylight processes for those wondering this was also true for other games tested as well such as overwatch for example these new KB Lake processes were quite good when it came to overclocking using just 1.33 volts I managed a 100% stable overclock at 4.9 gigahertz using one point four volts it was possible to reach five gigahertz but keeping the CPUs cool wasn't an easy task I could even load into Windows at up to five point one gigahertz though at this frequency it wasn't possible to complete all our stress tests in comparison our 6700 K processor maxed out at 4.8 gigahertz using the same 1.3 3 volts and going as high as one point 4 5 volts wouldn't stabilize the chip at 4.9 gigahertz so it seems when it comes to overclocking KB Lake is good for another 100 to 200 megahertz certainly not a mind-blowing result but it will no doubt keep overclockers happy using a fairly basic all-in-one liquid cooler the 7700 K did hit 95 degrees at 4.9 gigahertz the cooler used was the deep cool captain 120 ax those overclocking this chip will want something with at least a 240 millimeter radiator attached if I create an overclocking guide I'll certainly be using a more extreme cooling solution out-of-the-box using the same deep cool liquid cooler the core i7 7700 ki tled at 31 degrees and then under load one as high as 77 degrees the 6700 K was then installed in the same system it all 30 degrees but under loaded 81 degrees I had read reports indicating that 77 RK was a much hotter chip than the 6700 K that certainly isn't the case when comparing my two chips low ok so we've now looked at out-of-the-box performance for both the core i7 7700 okay and core i5 7600 processes we've looked at clock clock performance overclocking performance temperatures power consumption and integrated graphics performance out of the box the KB Lake processes were for the most part five to seven percent faster than the equivalent skylight processes of course as noted they are clocked around seven percent higher and when running a few clock for clock tests we discover that there is no difference at all between Kaiba Lake and sky lake so that's a disappointing no IPC gains to be seen then efficiency has been slightly improved though as some have pointed out Intel has been selling 14 nanometer CPUs for 18 months now so the process has inevitably matured in that time and this will help to improve efficiency overclocking looks to be slightly better with KB Lake and our sample suggests that overclockers can look forward to squeezing out another 100 200 megahertz I have seen reports of terrible temperatures for the core i7 77 ok so I don't want to say conclusively that it runs cooler than the 67 or ok but mine certainly does that's that I have an earlier engineering sample and looking at the data available online my 67 ok certainly seems to run hotter than the typical retail chip ultimately for desktop users the upgrade from skylake to KB Lake obviously isn't viable even for those running a Haswell or Broadwell process of the incentive to upgrade to Intel's latest platform just isn't there meanwhile those who purchased a core i7 4770k two and a half years ago are probably sitting there scratching their head wondering where they go next and I can tell you it certainly isn't the 7700 he'll if we look at the 4.5 gigahertz alts we see that even the Ivor bridge 3770k is hanging in there it's a good bit faster than the 7600 K anyway even the 2600 K max out quite well only trailing the 67 okay and 7700 K by a 23% margin in Gears of War for a very CPU intensive game that was tested with what is currently the most powerful gaming GPU available I guess for now we'll have to wait and see what aim DS rise and has to offer mainstream performance users in the end KB Lake looks like it's not much more than a sky like refresh and frankly this is how I feel Intel should have tried to pass it off but I guess for OMS and reach our six general refresh doesn't quite have the same impact as an entirely new seventh gen product line what's that sir you have an old sixth generation system you'll want to upgrade that to a new seventh generation model they are much faster anyway for us and throughs it looks like a nother disappointingly small baby step perhaps I'm being overly negative let me know what you think in the comments below I'm always keen to hear what you have to say for now though that concludes my cable 8 coverage I'm your host Steve and I'll catch you on the next one you you
