welcome back to harbor unbox now it's been 10 years actually almost 11 years now since Intel released its first quad-core desktop CPU the glued together called 2 quad q6600 and what a glorious cpu it was the 65 nanometer quad core operate at 2.4 gigahertz but back then boost clocks weren't a thing and CPUs operated on a frontside bus we've seen eight major architectural updates and four die shrinks spanning a decade yet in all that time Intel only offers up to a quad core for its mainstream product lines most of which is the KB lake based core i7 77 or okay which was released back in January of this year for 340 dollars u.s. however shortly after that AMD did something that we'd all hope they do but certainly weren't convinced they could or at least I wasn't convinced they could and that of course was to release a CPU architecture that was good really good a horizon certainly disrupted Intel's business as usual type attitude and it's been fireworks ever since in a nutshell aimed at Intel the hardest by offering more cause for less money that was kind of the strategy with bulldozer but the key ingredient here being that the cause didn't completely suck IPC performance is slightly down Intel's latest and greatest offerings but there really isn't that much in an Horizons efficiency certainly is very good so they're not really giving up anything they're actually the biggest advantage Intel has right now is their superior clock speeds and this is something a me hopes to address next year before and II can do that though Intel's heading back with their eighth generation Core Series and with that they're addressing one of Verizon's biggest advantages cause lots of cause although horizon 7 will still have a core count advantage Intel is now making six cores the standard for their high-end parts the new Core i5 and core i7 processors now packs six cores and that's going to have a very big impact on hand today we have the flagship model the core i7 8700 K which is based on Intel's latest architecture codenamed coffee Lake I also have the core i5 8400 but I'll be focusing on that CPU in another video shortly unfortunately at this time that I don't actually have the Core i5 86 under okay the unlocked core i5 but I will get my hands on one of those shortly as well as the core i3 models anyway for now their focus is on the big guy the 6 quart 12 thread monster known as the 8700 K designed to operate no slower than 3.7 gigahertz it will boost a single core as high as 4.7 gigahertz and under full load should maintain an operating frequency of 4.3 gigahertz each of the six cores feature a 256 kilobyte level 2 cache while there is a much larger 12 megabyte level 3 cache intel has given the chip a 95 watt TDP rating and once again they are using the LGA 1151 socket though this can be considered as like a version 2 as it will be in no way compatible with the previous KB lake or skylake cpus now the price has been increased from the 7700 K as the 8700 K comes in and a rather steep 360 dollars u.s. and that is a $20 price hike from the KB Lake flagship part it's also $60 more than AMD's risin 7 1700 that's the company's cheapest horizon 7 part and it is of course unlocked these 1700 X is also priced at 260 dollars but smart shoppers will opt for the cheaper 9x model I've personally had just as much luck overclocking both the X and 9x models to 4 gigahertz moving on it's great to see that unlike the high-end desktop sky like experts on the LGA 2066 socket the new coffee-like cpus still use the ring bus and not the mesh interconnect method which is used by the higher core counterparts this is great news because it means the 8700 k will maintain the 77 area k's gaming prowess and should if being in fact able to take things to the next level for gamers so without wasting any more time let's see how this thing handles jump into the benchmarks let's first take a look at memory bandwidth performance please note all CPUs were tested using ddr4 3200 CL 14 memory that in mind it's interesting to note that the core i7 87 ok does take a step forward from the 77 ok is now on par with the horizon 5 CPS with around 36 gigabytes per second and memory bandwidth that said though it's still trailing the rise in 7 models by around 2 gigabytes per second ok so let's check out the Cinebench r15 scores as luck would have it after a 3 run average the 87 okay matched the r7 1700 with a multi-threaded score of fourteen hundred and twenty three points that did mean it was thirteen percent sold in the 1800 ex but still an impressive result all the same actually what's really impressive here is the single core score and this explains how a six core Intel CPU kept pace with an eight core AMD CPU the 8700 K provides the same 195 point single thread scores of 77 okay and by extension the 77 40 X so the 8700 K is looking pretty solid all around it also completely dusts the core i7 7 heretics as well so kind of sucks if you bought one of those recently maybe all we have PC mark 10 and this gives us a look at how these CPUs compare in more general use case scenarios core count isn't that important for the most part here it's really all about the frequency for that reason the core i7 87 or K does extremely well outscoring the semi Tamarack 8 by 5 percent margin Excel is an office type benchmark which can utilize many threads especially when running the extreme Monte Carlo simulation 3700 K finds itself situated between the Rison 7 1700 in the 1800 x with a completion time of 2.5 5 seconds this also makes it around 13 percent faster than the core i7 700 x another 6 core Intel CPU testing with veracrypt we see that this time the 87 here ok trails the horizon 7 1700 though it is still around 10% faster than the core i7 700 X and 14 percent faster than AMD 6 core r5 1600 then moving on we have non-encrypted compression and decompression performance using 7-zip whereas hyper threading sees a similar level of efficiency when compressing and decompressing SMT is significantly more efficient for the decompression work here we sent the 8700 K does very well and it's around 50 percent faster than the 7700 K handbrake is a popular application for encoding and we've used to convert a 4k h.264 video to 1080p using h.265 and then recorded the average frame rate he'll arise in 7 1700 sped out 11 frames per second on average while the 1800 X managed 12 point 6 frames per second not bad but the new core i7 87 ROK went complete beast mode with an average of 13.8 frames a second making it 10% faster in the 1800 X 11% faster than the 7800 X next up we have premier and we know this application lacks cause but it also loves clock speed the new core i7 8700 K completed the encode in 195 seconds which is just a few seconds slower than the rise in seven 1800 X so a very impressive result for the core i7 CPU here moving on to some rendering tests we have blender and first up were running the rising graphic 27 test once again the 87 or K finds itself in a verizon 7 sandwich with a completion time of 25.8 seconds this made it almost 40% faster than the core i7 77 okay and Rison 5 1600 in this test the gooseberry workload paints somewhat of a different picture and this extreme workload the 87 okay is able to pull the head of the Rison 7 1800 excess now 14% faster and 8 percent faster than the 7800 X Corona comes as a standalone benchmark it renders a fix seen six times and we take the time it takes to complete the entire task this time the 8700 K is closer to the r7 1700 than it is the 1800 X but even so render time of just a hundred and forty-two seconds for a six core CPU is mighty impressive povery is another ray tracer it's been around for many years and we're using the official benchmark again the 8700 K is closer to the r7 1700 than it is the 1800 X but even so it's a good bit faster than the now redundant 700 X alright so time for a few quick gaming benchmarks before we look at the power consumption and temperatures here we're testing battlefield one using the DirectX 12 API with the ultra quality preset enabled all the games have been tested using the gtx 980ti in vegas 64 GPUs and first up we have the GeForce results even with the GTX 1080i at 1080p we are GPU limited battlefield 1 using the ultra quality settings for this reason the 87 ok is limited to the same 157 FPS as the 7700 K the horizon cpus meanwhile look quite a bit slower despite delivering over 100 FPS at all times that said it is worth note that can be an issue with the rise in CPU is when using an NVIDIA GPU in DirectX 12 titles so let's check out the Vegas 64 results although we are slightly more GPU bound here with the slower Vegas 64 GPU what's key to note here is that while the 8700 K and 77 ok frame rates are slightly reduced the and CPUC a rather significant boost in framerate there of course still slower than the Intel CPUs but the margin is significantly reduced we'll take a look at this again in a moment while trying to remove the GPU bottleneck next up we have ashes of the singularity and here the core i7 87 okay really shows what it can do as it roughly matches the core i7 7820 action thread Ripper 1920 x in this core heavy game the average frame rate was boosted by 17 percent over the 72 ember ok and 25% over the horizon 7 1700 swapping out the GTX 1082 I for Vegas 64 actually helps put the 87 okay ahead of the thread Ripper CPU though with that exception the rest of the margins are really much the same moving on a civilization 6 we see the core i7 87 ok is roughly on par with the 77 ok as well as aim DS rise in 7 1800 X and this is with the GeForce GTX 292 I so some pretty competitive looking results here please note that in my Intel Core i 979 80 XE and 79 60 X reviewed the horizon 7 frame rates were higher than what's shown here I wasn't able to determine if this was a mistake made on my behalf or if it was down to a game patch or a driver update previously the 1800 X was pushing 112 FPS on average with Vegas 64 and now we're down to a hundred FPS I'm constantly retesting and sometimes we do find a change like this in some games mafia 3 for example was dropped from the testing as the performance often changed quite dramatically with each update anyway it's worth noting that we are still seeing vastly superior performance on the rise and 7 CPUs with Vega 64 it's just not as extreme as I showed previously whereas the 8700 K was 4 percent faster with Vegas 64 compared to the GTX 1082 I the 1800 X is almost 20% faster so civilization still providing some very interesting results when comparing the g-force of Radeon GPUs in the DirectX 12 API the last game we're going to look at is f1 2017 at first up we have the GTX 1082 our results here the 8700 K was actually slower than the 77 okay which is a bit odd it seems this title can get a bit confused when there are more than 4 cores on offer that said though the 77k is clearly faster than the 72nd RK and this is the same case when looking at the rise and 5/16 hundred and fifteen hundred X even with a sixty-four we find much the same between the 77 okay and 8700 K though there is a bit of reshuffling in the midfield and it is the Scarlet hex parts that seem to lose out the most to you overall though the 87 okay was slightly slower than the 70 Center okay in this title okay so before wrapping up the gaming let's just quickly retest battlefield 1 at the ultra low 720p resolution to try and remove the GPU bottleneck while still maintaining the ultra quality settings previously the 8700 K was only able to match the 77 okay it wasn't much faster than the 7600 K however by removing the GPU bottleneck we're running to another issue battlefield ones 200 FPS hard cap the 8700 K was able to keep the GTX 1080i at 200 FPS for the majority of our tests and this means it could be much faster than the 10 percent margin we see here over the 77 okay it's now 27% faster in the 7600 K and 55 percent fast in the horizon 7 1800 X although the Rison 7 1800 looked how should I say almost pathetic with the GTX 1080i it's a bit of a different story with Vega 64 here it's 20% slower than the 87 okay and while that's still a fair old margin it is much better than what we saw previously with the GTX 10 atti this every similar cake is also quite a bit faster than the Radeon graphics card as well but unfortunately the 87 RK is again limited by the game's artificial frame cap anyway one thing's for sure the 87 or K is an incredibly powerful gaming CPU next up we have power consumption it's important to measure using software that stresses all cause I found that Corona works very well for providing accurate results so these load figures are based on the corona benchmark after a single pass and I'm reporting the maximum logged a result this is total system draw and I'm using the Quebec power mate to measure from the wall when it comes to power draw the core i7 87 or ek is certainly on the higher side but it's not as Extreme as what we saw from the sky like X CPUs the 700 X for example was not only slower in every single test but it also pushed whole system draw 17% higher when compared to the risin 7 1800 X 280 700 K did increase system consumption by 18 percent so until isn't quite as efficient as they have had to increase frequency quite aggressively in order to keep pace with AMD's 8 core rise and 7 processors still overall I'm impressed with what Intel's me now to achieve here the only 700 case it looks very solid all around now I'm very keen to see how the thing overclocks if you deleted your 77 or okay you could probably get about five gigahertz out of it maybe 5.1 gigahertz with very little effort we managed to push my 8700 k chip to five point two gigahertz and here it was 100% stable I could even boot into Windows at five point three gigahertz and run a few tests but it will require finer voltage tuning for 100% stability we didn't really have too much time to play around with overclocking just yet so I settled on five point two you hurt I felt like that was probably impressive enough as it was this impressive overclock also means that the AE 700 K is now able to match the multi-core score of the 1800 X in Cinebench r15 well devastating the single thread result that said you can of course overclock the 1800 X and that does allow it to remain ahead for the proactivity workloads speaking of which this is how the overclocks changed the corona results overclocking the 87 or okay meant that it was able to complete this task 15 percent faster than its out of the box configuration that said though the 1800 X did see a 20% improvement once overclocked the horizon 7 1800 overclock increased system power draw by whopping 42% and this was the exact same figure seen when overclocking the 87 or okay as well neither provided anywhere near that kind of performance gain so as usual the efficiency kind of goes out the window once you overclock I haven't had a chance to build my new core i7 87 or okay test system yet but you can bet I will be doing that over the next few days or so and it will become my new GPU testing machine for now though I'm using the deep core captain 240 X RGB it's an all-in-one liquid cooler with a 240 millimeter radiator it's a decent solution though the Noctua NHD 15 air cooler has been reported to deliver slightly better temperatures on an overclocked 77r okay for example that said the d 15 is about as good as air coolers get anyway with a room temperature of 21 degrees the 8700 k idled at just 25 degrees when stressing both the CPU and FPU temperatures did hit 84 degrees meanwhile just stressing the CPU saw temps max out at 60 degrees then once overclocked to 5.2 gigahertz running the CPU stress test we did get within 6 degrees of the t.j.maxx peaking at 97 degrees briefly obviously a dealer would really help tremendously here for those seeking more extreme overclocks and a more extreme cooling solution probably wouldn't hurt either Intel's made some pretty big performance claims when it comes to the eighth generation core series but with 50% more cores on the core i5 and core i7 parts claiming up to 25% more frames in games isn't that bold that said though are these gains just down to the outer cores are are there some architectural improvements made here to increase the IPC some sources have suggested up to a 10% increase in IPC so let's look into that what I've done for this test is locked the 8700 K and 77 or okay at 4.5 gigahertz I've also disabled two of the 87 arcades cause essentially mimicking the configuration of the 77 ok first up we have seen a bench r15 as you can plainly see the four core and eight threads clocked at 4.5 gigahertz just like we have with the 77 okay 3700 cade delivers basically the same scores after a three run average it was slightly slower in the multi-threaded test as expected that almost 50% increase in score comes from a 50% increase in cause testing with Corona we again see the semi 7k is slightly fast in the 87 okay when they are both matched with the same core and thread count at 4.5 gigahertz again adding two more cores makes the 87 RK almost 50% faster and finally power consumption this is an interesting one the 87 okay does pack 50% more level 3 cache to support those extra cores and this isn't something we can disable when turning off those cores so here we see that when comparing the four core 8 thread configurations the 87 or K does push system consumption 10% higher at the same clock speed then with those extra cores enabled the total system drawer is increased by 33% okay before we wrap this review up we should probably check out a few price versus performance scatter plots to work out just how well the 87 our case stacks up in terms of value looking at the Premiere Pro CC results we see at the core i7 8700 K is a good step forward from the recently released 7800 X it's both faster and cheaper compared to the horizon 7 1700 the 8700 K was 8% faster but it also costs 20% more still it is much better value than the r7 1800 X overclocking does muddy the water a bit here so we're not going to focus on that for this review I'll cover the overclocking stuff in a bit more detail in a future video for near the r7 1700 looks too content creators with the best value option but the core i7 87 okay is certainly a viable option and I didn't feel this was the case with the superhero ex for example for the extreme blender workload the 87 okay does very well again it's 20% more costly than the r7 1700 but it's also 20% faster out of the box in terms of value the r5 1600 is still the best option but for it to get anywhere near the stock 8700 have to overclock it to at least 4 gigahertz so Intel puts forth an extremely compelling option here for gamers especially high refresh rate gaming it's pretty obvious that Intel CPUs are the way to go in terms of performance and value as we saw with the 720p results the 8700 K was GPU limited at 1080p I snuck in the 720p testing last minute as I finished up this review so I don't have any price versus performance scatterplot stuff for that but needless to say Intel wins quite comfortably here using Vega 64 we are again GPU limited though it has to be said the rise in CPS perform much better with a radeon GPU when using the DirectX 12 API so if a game is hoping to maximize their dollar the Rison 5 1600 still presents a great value option and is arguably the most cost effective choice for anyone who isn't after extreme high refresh rate type gaming finally when looking at the ashes of the singularity results with Vega 64 we again see an extremely impressive result from the 8700 and it's a good bit fast in the previous gaming King the 7700 ok these figures also really suggests to me that the 87 R K isn't just the new king of gaming right now but it also will be well into the future well they have an intelligent you main stream flagship Core i7 processor and what a beast it is for gamers seeking the ultimate gaming experience that simply is nothing better than the core i7 87 ok right now it really has no weakness out of the box the performance was incredible overclocking is probably even more incredible and power consumption really was impressive for a CPU running at well over 4 gigahertz out of the box and for all those reasons it's certainly going to find its way into my new gaming rig speaking of which I will be using the new MSI a Zed 370 godlike and that board the board here to my left was used for all their testing in this video and it did enable that impressive 5.2 gigahertz overclock I'm also keen to see how much further I can push the 87 ok once I do build my new system so little bit more tinkering to be done there but it should be a bit of fun the only slight down it is of course the price and I'm not talking about the godlike though that is a ridiculously expensive motherboard I believe it's about 700 Australian dollars so yeah it's the cream of the crop MSI say anyway as for the 87 ook at three hundred and sixty dollars us it is a little bit more expensive than a semi semi okay the CPS replacing but make no mistake the 87 okay is a serious step up from the 77 okay but at the same time it's also a bit of a costly affair particularly when compared to something like the horizon 5 1600 for example I feel the majority of gamers will be better served by the r5 1600 though having said that I'm yet to check out the coffee-like core i5 range and I'll be doing that very shortly still the 8700 K really only makes sense for those after extreme frame rates with the latest and greatest gaming hardware all those playing cs:go at 720p using low quality settings on the GTX 1060 anyway as I said all this framerate madness isn't cheap once you dish out three hundred and six dollars for the 87 okay you really want to spend at least another hundred dollars or so on a decent cooler realistically you could spend as little as twenty dollars on a basic air cooler but I feel like that's doing this incredible overclocker a disservice anyway let's say $20 to be conservative now we're at $400 and then once you factor in a decent said 370 board for say around 150 dollars you now have a $550 combo moving on from gaming though what about productivity well the core i7 87 or okay has the horizon 7 1800 beat quite convincingly it almost wasn't a contest that said the 1800 X was already a dead ship and our eyes before the 87 okay even came along compared to the r7 1700 the 8700 K is at best on par in terms of value but with both overclocked to the max the rise in seven CPU should offer a little more even so it will vary from one application to the next and I'd say overall they are very similar again though those on a budget will up for rise and as it is cheaper and it will deliver a similar level of performance without much trouble still the 8700 K really has proven to be much more of an all around us certainly much more so than the 77 or okay was therefore overall I really like Intel's new core i7 87 okay and I can't wait to check out the rest of the coffee-like range 2017 has already proven to be in apps we've spectacular year for PC hardware and it's great to see so many impressive options available to consumers with that I hope you guys enjoyed the review I'm your host Steve see you again soon
