what's up guys welcome back so as your YouTube subscription feed will undoubtedly indicate AMD's high-end line of eight cores sixteen thread Rison seven chips have just hit the market comprised of three SKUs based on the Zen architecture from lowest to highest they include the r7 1,700 1,700 X and the 1800 X at their press event last month in San Francisco AMD revealed an aggressive pricing scheme and touted some impressive data against the competition bear in mind of course to always take manufacturer benchmarks with a tiny grain of salt while I won't be able to give an analysis of the r7 lineup in its entirety today AMD did send me home with their flagship r7 1800 X a response to Intel's Core i7 6900 pay for about half the MSRP at just 500 us the price points will be easily confirmed by trusted online retailers so that leaves the proof of performance on the shoulders of the reviewers to see if the 1800 X is the disruptive animal AMD claims it to be that said there's still much to discuss about team Reds newcomer before it steps into the Octagon with its heavyweight rival to reiterate some of the vital specs to 1800 x packs a lower 95 watt TDP than the 60 900k with a base clock of 3.6 gigahertz and an auto boosting technology that functions similarly to intel's turbo boost in multi-threaded workloads the risin chip will boost all cores to 3.7 gigahertz a boost to 4 gigahertz is possible but this only applies to a single core during a single-threaded task during my single core runs in Cinebench r15 hardware monitors showed one and sometimes two of the cores boosting to 4.1 gigahertz while the others remained at their idle state frequencies this extra 100 mega Hertz is courtesy of AMD's extended frequency range or XF our technology which bumps the core to 4.1 gigahertz if cooling conditions allow as far as I know AMD hasn't confirmed exactly how this is defined but clearly my Noctua air cooler and ambient temperature of 24 C helps XFR reach its threshold since all but one of today's tests utilize multiple cores however exif are and the single core boost feature won't have much of a positive impact on performance so I decided to overclock all cores on both CPUs for two benchmarks at AMD's press events the rep hosting their overclocking demo recommended enthusiasts not push past the 1800 X's stock V core of 1.3 5 volts so staying at the base voltage I was able to achieve just 3.9 gigahertz before reaching any instability suffice to say if you were hoping for overclocks well beyond the 4 gigahertz mark you'll be sorely disappointed unless you keep a tank of ln2 handy the rep did mention the facility lottery will pay out the occasional 4 or 4.1 gigahertz part with 4.2 gigahertz capable chips being more of a Powerball jackpot now given rising slow TDP compared to its Intel counterparts I was excited to test thermals today but for starters the chip is still too fresh to be fully recognized in the usual suite of monitoring apps and even if they were I've been informed by the ever so perspicacious Steve of gamers Nexus that writing temps may not be represented properly via the software due to AMD using similarly faulty temperature diodes as their older FX chips - no one surprised gamers Nexus has the proper equipment to sidestep this issue so in the description I've linked their rise in video for those interested to learn more you probe that chip you hear me Steve you probe it good now we're just about ready to go gloves off with these two but first a quick look at the separate test beds we'll be using you'll notice our 6900 K has been overclocked to 4.3 gigahertz and we're using the same memory capacity and frequency albeit a quad core channel kit 4 X 99 the knock to a cooler on our 1800 X was a special AMD Edition that only included an am 4 bracket so for the i7 I employed the most similarly Specht air cooler I had on hand this cooler master hyper 212 Evo both systems are running the GTX 1080 founders Edition with the latest 378 dot 66 Nvidia driver and all games were tested at 1920 by 1080 2560 by 1440 and 3840 by 2160 aka 4k without dragging this out any longer folks it's finally time to see how these two CPUs stack up and who will go home with all the glory assuming they don't tie then I guess they would split the glory it doesn't matter ladies and gentlemen here are the benchmark you all right so as the data shows the 1800 X is by far and away the fastest processor from AMD that we have seen in years with the current pricing at the time of publication of this video it's an easy pick over the 69 hundred K for video editors on a quote-unquote budget as it delivers some quick encoding times that would likely be unmatched by a quad-core i7 until 6 core 6800 K may still be in the running however in game our two contenders saw a handful of snail mates but if you look closely this was a repeatable trend at the higher resolutions of 1440p and 4k indicating a GPU bottleneck at 1080p when the test becomes CPU bound the 1800 X falls behind every time suffering the most in doom apart from having favorable 0.1% loathes and Metro last light with concerning 0.1% lows and 8.5% slower averaged frame rates now it's been established that the 7700 K is higher IPC often makes it the better gaming chip over the 6900 K so this positions the 1,800 X as a less compelling option for diehard gamers especially at a 43% price hike over flagship KB link one area where eight core Rison appears suited for gaming is when live encoding is thrown into the mix playing doom on ultra quad HD while streaming out 1080 60 scaled all 16 of our logical cores and kept up with the 69 hundred K by delivering fluid gameplay and zero dropped frames in this regard the 1800 X makes a case for hardcore streamers who might value the encoding capabilities over raw fps particularly if they'll also be cutting up highlight reels with video being software additionally users interested in purely gaming should continue looking to the i5 and i7 KT like options for now from a gamers perspective AMD may have lost this first battle but the war is far from over as we inch ously wait to see if upcoming rise in parts will offer higher instructions per clock to better compete with kb lake that's all I got for now guys so let me know in the comments what you think of rising so far and how its measured up to your expectations before you guys go don't forget to toss me a like on this video if you enjoyed it you can also check out my store and get 5 bucks off if you buy one of each of my two new shirt designs evolution and crystal RGB because together we can light up some crystal as always I am Kyla bit with thank you guys so much for watching subscribe to the channel if you haven't already and I will see y'all in the next
