    Mere 3% is hardly unlikely. That's what AMD can gain from increasing memory clock from 2933MHz to 3200MHz and enabling bit tighter timings. Even from macroscopic design point of view, AMD did huge design changes. We do not really know where that lands chip in terms of memory access, cache latencies. But I would say that AMD aims to improve.
    What AMD did with cores themselves?
    Zen 2 addresses this shortcoming by doubling each core's SIMD register width to 256 bits. The floating-point side of the Zen 2 core has two 256-bit floating-point add units and two floating-point multiply units that can presumably be yoked together to perform two fused multiply-add operations simultaneously.
    ...
    To feed those 256-bit-wide execution engines, AMD also widened the load-store unit, load data path, and floating-point register file to support 256-bit chunks of data.
    Source.
    I would expect around 10% IPC gain on average (depending on workload). But 15% is not out of question and some workloads may do even better.

    My theory on this is Intel has probably been sandbagging for years, why innovate when there's no competition? they were probably bashing out these ~5% IPC generational improvements just to sell more CPU's and motherboards to those who upgrade every generation.

    Bulldozer to Piledriver had a pretty decent IPC upgrade, I can believe it. AMD is really good on tuning their core technology.

    When the Intel core architecture first came out newer gens provided decent gains but once they pushed it to the max IPC gains were only 2-3% and they have technically been flat for the last 3 gens besides pushing clock speeds. Zen was a conservative release and Zen+ had slight tweaks. Zen 2 i can see doing 13% with some heavy tweaking on the IO controller and reduced latency core communication more tweaking on memory sub timings by default. Zen is quite scalable/tweakable they also have way slower L1/2/3 cache and higher latency than Intel so tweaks can be applied there also along with improve data prediction. There is alot of things they can do to get that 13-15% AMD is taking Intels approach of tick tock.

    I am still sceptical of clock speeds however seeing how Zen has slowly been coming along in that department.

    It would be so great if all the rumors/leaks end up being true. I have no doubt that it will be good though.

    It´s BRILHANT what AMD has been doing last years! This prove that ALL is transient!
    Zen2 will be my next setup after a very long time, and I am very proud to give my money to the best option today in the marketing talking about cost x performance (perhaps now the both terms in the top).
    Skeptical people and Intel fanboys are doubt one more time, but AMD will bring the TOP CPU performance at ALL (games and data) because the Zen tecnology is very MATURE... and the jump of 12nm to 7 will be very powerful. IF... the ZEN2 runs with ALL CORES at 5.0GHZ with DDR4 4000MHZ (with good latency) the Darkness time is already planted there!
    Congratulations AMD and good fortune to the blue side... they will really need!

    BS unless it can do 6Ghz iam not buying it! Joking aside I was expecting something Huge from Amd zen2 but even with these ipc improvements I would still rather have a 9900k. Zen is way cheeper I give em that much less then half price.

    What I'm afraid of is that they are measuring IPC gain in some AVX/AVX2 workload, since Zen/Zen+ is limited there to 128-bit, instead of the full 256-bit that AVX(2) can offer. Zen2 is fixing that, however its rarely used by games, for example, so it wouldn't result in any gains there.
    Getting full AVX1/2 is still a noteworthy gain, but folding that into some generic IPC increase would be .. misleading, since its not a generic gain, but only in applications that use it specifically.

    What I'm really interested in is what all-core clocks it can get for a 24/7 OC under water/AIO. If thats in any way decent, I'm definitely interested in a 12-core variant. But I definitely want 4.7+ all core for that, since I can run my "aging" 14nm Intel 10-core on that today already.

    AMD "leaks" have a serious history of vastly overstating actual performance.

    It is hard to believe this is accurate.

    Engineering sample, and don't know if that is base, or all-core boost. Lets say it is base, what exactly is not "huge" about that? I'm only pointing this out because it sounds like you are reading this as though its not an engineering sample as well as knowing what the all-core boost is to make your opinion

    I’m going to be the coolest kid on the block with a starter 6 core processor. It’ll be since upgrade for my 1600x.

    If the final product can make it up to 4.6 on all cores and the temps better than 9900k the market will switch trust me, and i will be the first one jumping next to AMD from my 6700k right now.

    Yes, everything before Ryzen has quite a bit of marketing jargon to create more of a buzz...true, but the IPC improvements of Ryzen actually were better than they promised.
    __
    I do hope more switch to AMD, we need better competition in PC stuff, as we can see the competition in the phone business is making sure just about all actors are trying to make the best phone possible or at least the performance keeps on going up

    4.5Ghz and the extra IPC sounds nice. If it is 8 cores then no need to switch up for quite some time, because PS5 will unlikely run at 4.5Ghz anyhow.

    My primary computer is Broadwell 5930 at 4.6 GHz. I am not hurting at the moment but my next CPU purchase will probably be AMD. In the 486 days I called up AMD and asked if AMD's 486 was pin compatible. They let me speak to an engineer who explained the AMD 486 was not actually pin compatible with Intel's.

    Sadly I went with Intel that time, but the whole 486 platform was a disaster. I had a Young motherboard that never worked. I'll take a good 286 any day. I never used an 8080 but I did use an 8085. I was into mini computers and mainframes before that.

    Well if the 15% IPC is true then AMD will be basically on par with Intel clock for clock. Now the big question is how far will the final products boost compared to Intel CPUS?

    See difference of productivity with 6C/12T chips... around 3% mostly and sometimes AMD wins. Difference in gaming is bigger. From their numbers 2600X is around 7~12% slower in those few games tested than 8700K. But then look bit more and see that gap between 1600X and 8700K has been reduced by half by that 2600X.
    ...
    1600X is 16,4% slower in FC5 than 8700K. But 2600X is only 7,8% slower than same 8700K. (That's tweak between Zen and Zen+ where many claimed that there are no changes...)
    - - - -
    If those 15% are true and would be across the board (which they are not as that is some kind of average), AMD would claim productivity win regardless of clock, because there both sides end up using all cores and that reduces intel's clock advantage... or results in quite some energy waste.

    And in gaming, it would reduce difference enough to become unimportant.

    Maybe time to long AMD's stock for a quick profit later this year :)

    Clock-Speed isn't everything that makes a CPU better.
    Zen2 is a new architecture based on 7nm, plus it is patched against Spectre and it isn't affected by Meltdown nor Spoiler, while Intel CPUs still are.

    Even with Zen and Zen+ AMD already has the upper hand against intel, as in benchmarks I see them mostly at top in multi-core performance, not intel.
    Might be true that single core performance on intel is better than AMD up to some extent (as of right now). However, there again AMD has a fair price policy instead, thus you can keep your kidney!
    For those who are gaming-oriented who must have the better single-core performance advantage regardless of the price policy:
    Let's not forget that a few months ago a Zen2 prototype model was running head in head with an 9900K, while Zen2 was consuming half the power that the 9900K does, which you can safely assume that Zen 2 was very most likely not running on full potential at all.

    Anyway, having no high hopes or expectations isn't necessarily meant to be something bad. It may as well boost the "surprise" effect when the final product launches.

    He did write 2700K :) And I assume that's what he meant by IPC increase?
