first up I do want to mention the winner of the candid GT x 1080 giveaway that person is an AFOL right hand sia sorry if i butchered that name it looks like you're from india and if also i'll be giving you a DM in instagram in the coming hours after I edit this video here congratulations on the win again it doesn't matter where you live folks I mean it's either gonna be the card itself that I deliver to you or if that's not possible I'll be sending you the equivalent US dollar amount of whatever the card costs in this case candid delegated 620 US dollars for GT X 1080 so worst case that's what you'll get but I'm gonna try my best to get the card over there because another card is extremely expensive in many places around the world now let's discuss the topic of this video and that is AMD Zen vs. intel kb lake in particular i want to test the viability of AMD Zen claims there are 40% IPC jump and also they're very intriguing head-to-head comparison between their 8 core 16 threads and behemoth and the i7 6900 k which I should mention is a $1000 processor this video is not going to be very long I'm not a huge fan of strictly speculation videos although there are a few things that we can say are substantially different between Zen and old FX architecture namely bulldozer and piledriver architectures we'll also be using excavator as a stepping stone if you will to get to that 40% IPC improvement between excavator and Zen that AMD has been touting for months and on Intel side will be discussing whether or not waiting for KP lake is even a smart idea especially if you're sporting a skylake processor right now and whether or not Zen has anything to worry about when it comes to that new Intel architecture which spoiler alert isn't really all that different first things first let's validate AMD's claim that Zen is in fact a 40 percent IPC improvement over excavator thankfully we have a physical benchmark for this but I will say as a disclaimer this is a test conducted by AMD in an effort to promote an AMD product I'm not sayin that AMD would skew their results in an effort to make their product look superior to their competitors but this is a company we're talking about I would say the exact same thing about Intel Starbucks you get the point if you want my two cents I say wait into our viewers like myself and others get our hands on these processors put the head-to-head clock for clock and we'll really see what these things can do until then I would take everything that you see with a grain of salt so in this test right here an AMD eight core 16 threads n CPU with simultaneous multi-threading it's basically AMD's equivalent to hyper threading barely outperforms an i7 6900 k both of which are running at the exact same frequency this is just one test mind you and i do expect that AMD took that engineering sample and threw it in a batch of tests against the 6900 k found that the blender test resulted in the greatest disparity and decided to showcase so that went to the public just because it does make send look the best i don't blame them i would do it too it is possible that the 6900 k outperformed the Xen counterpart and something like Cinebench r15 they just decided not to show that one because well it's not gonna make their cpu look as good as the thousand-dollar competitor nonetheless we can use this performance test to validate AMD zenzai pc claim now because IPC which stands for instructions per clock is a measurement essentially of single core performance at a given frequency we can correlate multiple architectures this isn't an exact science and you can't correlate these relationships to frame rate increases for example they just give us rough estimates of general architectural improvements and how much faster a CPU can process data let's start off with piledriver as our baseline this is the FX line up the FX 6300 8350 you get the point because it's our baseline we're gonna say that this IPC is 100 it's just easier to correlate that way but we could say it's one a million it's an arbitrary number as long as all of our other scores are in reference to that baseline we'll be good to go the first major jump for AMD was the release of the excavator architecture a notable 15% IPC improvement over piledriver you get these numbers by the way by multiplying the equivalent decimal increase in IPC by the previous baseline so in this case point 1 5 times 100 take that product and add it to the previous baseline that's 115 you're seeing here and now for the jump from excavator to Xen AMD does of course claim the 40% IPC boost so take point 4 multiply it by 115 and then take that product add it to the previous baseline of 115 field roughly 160 or so which you can read this two ways you can say that it's either a 40 percent improvement over excavator or because piledriver is our baseline of 100 roughly 61% IPC improvement over piledriver now let's quickly move on over to Intel Ivy Bridge had an IPC improvement over at piledriver of about 50% or so and these architectures were released around the same time at this point AMD favored higher core counts and Intel favored higher single core performance which is why you see these IPC disparities here one company baked on one thing and the other company banked on another so with Ivy Bridge is our baseline on the Intel side at roughly 150 we can correlate the other IPC improvements from Haswell to Broadwell easy to skylake if you notice here these three jumps are indicative about a 4% IPC improvement over all Intel really hasn't been pushing it lately and that's something that I hope Xen changes if we do the math this Lance has well at 156 Broadwell e at 162 and skylake at 168 now let's merge both our Intel and Xen IPC graphs and check that out Zen and Broadwell e are literally neck-and-neck I would say within the margin of error if our original IPC improvements are correct and that falls exactly in line with what AMD showed us in their blender test now because of what we just saw I would say with relative certainty that what AMD did show us with their 8 core 16 thread CPU is accurate now this goes back to something we mentioned just a bit earlier when we talk about the generation jumps from Haswell to Broadwell e to skylake and even a kb lake the focus for them has been more on single core performance improvements and not necessarily packing more cores into a single die this can have substantial impacts on the frame rates that you've seen in games as well as how programs utilize their various cores at their disposal now frequency also plays a role there essentially cores versus clocks we've discussed that in a few videos but when it comes to AMD it seems like Xen is taking the exact same approach that its predecessor piledriver did several years earlier what this tells me is that AMD is still focused on future proofing their CPUs banking on the fact that multiple programs will be able to utilize more than four cores efficiently in the next few years that by the way is what ultimately led to the downfall of bulldozer and piledriver back in 2011 see this video right here for more details nonetheless based on what we know and can safely speculate I do expect that a fork or eight threads n CPU will compete admirably against a 6700 case skylake counterpart clock for clock that's good news for those are you interested in something that's well more affordable than the Intel equivalent now let's change vantage points from Intel's point of view kb lake not a huge improvement over sky lake there are few architectural changes we're still running on a 14 nanometer process a few changes in the h.265 codec how videos are interpreted TDP power draws slightly different but for the most part it's just a refined 6700 K and you won't see more than any difference with the KB Lake processors over the skylake processors maybe when it comes to motherboard features and things like that but if you're currently sporting a 66 or 67 hundred K or I would argue even a 4647 90k that jump from house well or sky lake 2 kb lake is not justified by a 350 or so US dollar price tag you could make the case that kb lake brought substantial improvements to the mobile side of things actually you know what not you really can't apart from marginal battery life increases I would say same thing buying a 6200 u instead of a 7200 u is actually going to be the smarter thing to do if it means saving 300 bucks it's just the trend until it's been on lately and I expect that a large chunk of that reason is because AMD really hasn't given them anything with which to compete I mean just look at these IPC changes for Intel in this case we want to see a very shallow trendline indicative of substantial improvements from generation to generation but we're not seeing that we're seeing a very sharp trendline so when's n finally works its way into the mix we can expect one of three things to happen with respect to Intel the first is that Intel finally lowers its CPU prices be very skeptical of this one I am for sure because if you look at something like a 44 60 that the processor is still gonna put you back 170 or so US dollars and if you compare that to a 6400 the skylake counterpart that processor is about 180 bucks or thing at a $10 disparity from generation to generation these processors don't depreciate very well and people still buy them the second thing that could happen is until radically changes the architecture of either its mobile or desktop CPU lineup in the future against setting itself apart from AMD creating a sort of barrier to competition and ultimately not lowering its prices at all and then there's the third thing until continues to charge the exact same price as it used to charge for its future CPU generations that's actually the one that I think will happen I don't think Intel cares that AMD is finally competing I think that they think a majority of its consumer base will remain a majority of its consumer base that's bad news for AMD and that's definitely bad news for us if you liked this video give it a thumbs up give it a dislike if you feel
