    While AMD has already plans for 5nm, Intel is fine-tuning their 14nm+++++++++++ process.

    Looking forward to Zen 2.

    I wonder why they are asking questions which have been already answered. 7nm were sampling some time ago. By now they are likely in process of ramping up production. Q1 2019 is almost certain as they will not take year from finishing design and successful sampling to release. Ryzen 3xxx Q1 may be possible too. Maybe early Q2.

    They should ask questions closer to metal. Like how much more power efficient 7nm is. Or if they achieved clock improvement target.
    Those were not answered, yet and there is good chance that some nice bits of info will come.

    I remember some time ago there was information floating that we may see 5.0 GHz mark reached on 7nm ryzen. Personally, I doubt that, however, 4.5 out of the box seems possible, and 4.6-4.7 with OC.

    If that will be the case, its perfect all-rounder CPU for everything - movies, games, production, day-to-day stuff.

    Well, IIRC that info was from foundry. That their 7nm is capable doing it. But then there is CPU design itself. While Zen/Zen+ was 100% held down on clock by manufacturing process, it does not automatically mean that 7nm capable to reach 5GHz will fit Zen2.

    I wonder if we will have to bench games on 480 p with those so we can declare intel the gaming king again!

    My 4770k lately became unstable on 4.4, so I tuned it down to 4.3 @ 1.225v

    Hell, I can tune it down to 4.2 and it won't bottleneck anything due to the resolution I have - 3440x1440.

    We always have 240p or maybe 144p. Just to see how that 5% IPC difference will be felt in 5 years with a better GPU. Riiight. Like 5% can be felt in any way.
    Also, this high refresh rate thing is another big BS to entice buyers to buy the more expensive product just for a marginal difference. I guess stupid is not the one who asks, but the one who gives.

    See you in the court of law.




    Using 100Hz UWQHD display , with plans to buy the 200Hz one when it finally gets released.

    High refresh rate is not BS. But he is right that using unrealistic scenario to compare CPU is stupid.
    If you compare CPUs on 720p and GTX 1080Ti, you are doing this comparison for one of two reasons:
    - To show difference someone with such setup gets (Likely nobody plays that way on such setup)
    - To show that if there was no GPU bottleneck, this CPU would do better than that

    Neither of those is relevant outside of those tiny scopes. As 240Hz screen gamer I do acknowledge that I mostly play with fps limit set to 120 for isometric RPGs and games with limited motion.
    And higher limit with fps games. There is very lovely difference in user experience with higher refresh rate screen.

    So while I do advocate high refresh rate, I do understand that most of people are fine with 60Hz, have no need for top-end GPU nor CPU.
    Maybe you could try to show bit of respect to others by acknowledging their opinion even if you do not exactly like it.
    In the end, user experience is not exact science where you can say TRUE/FALSE as reply to statement.

    Seems like a wise decision to have Epyc get first treatment, for a few reasons:
    1. Now that Ryzen has proved its worth, the server market is where AMD's real money will come in.
    2. AMD can offer higher core counts than Intel and at significantly lower prices (you can buy an entire fully-equipped 32-core Epyc server for the price of just a 28-core Xeon) while having competitive performance. Zen 2 will be even more compelling. The sooner they get a head-start on this lead, the more profit they'll make. Intel will eventually make a product that is more competitively priced.
    3. Servers don't tend to care about very high clock speeds. As everyone knows, higher clock speeds tend to affect stability. GloFo and TSMC may have figured out how to get 7nm, but it probably isn't refined enough for desktop use with higher clock speeds. If Epyc still doesn't buy AMD enough time, they could also focus on mobile chips, which also don't need high clock speeds. Hopefully by the time those are released, these companies will have got 7nm totally figured out. This of course is assuming there are even clock speed issues with 7nm in the first place.

    Zen 2 sounds more and more like my next upgrade.

    Moreover- think about the space saving by using 64C Epyc vs max 28C Intel!.
    More PCIE lanes/Cores - much higher Density!

    dude, you know way more "inside baseball" than a financial reporter. this guy is excited just because of the yield creates lower costs, he could care less about what we care about.

    "AMD Zen 2 nm architecture starts with EPYC CPUs - Talks 5nm also" Think there is a 7 missing in there somewhere...

    schmitbag, my thoughts pretty much. The GloFlo 7nm process was built for very high frequencies of which you really won't need in 99.9% of the server CPU market. As long as TSMC's process gets significantly high enough in frequencies and does it without a ton of heat then this approach could be genius. AMD will also have a lot more production capability splitting up enterprise and and desktop manufacturing. I suspect both the server and desktop products are going to be a huge success and AMD will need the expanded manufacturing capabilities. Lisa Su is on a freaking role.

    That is all true but at least the design was 5Ghz+ vs GloFlo's 14nm lpp which was a low power low frequency designed process that had targets of 3Ghz. I think it's safe to say if AMD's design could hit 4Ghz on on that 14nm lpp node it will likely hit around 5Ghz on the Gloflo 7nm node. Fox, I realize he was reading foundry specs into what Ryzen could do but likely the two won't be to far apart.

    5nm is still years away. 2021 at the earliest

    On every PC, ever, there is always a bottleneck. Always. To think otherwise either you're expressing it in a way to exaggerate for effect, or if you truly believe that, you don't actually understand how bottlenecking works or what it means.

    4.2 is a bit low for that CPU. Unstable "lately" ? That means either one of two things. The CPU is dying, was always unstable but now is becoming more apparent, or you have too much dust in your heatsink etc. Or maybe just the wrong combo of bios settings (LLC etc).

    that "Title" is very irritating...
    at first i thought,m whaaat 2nm??? where, how, what...

    the wording is a little irritating.

    Ha yes BetA it is. I read the same thing as it does say AMD Zen 2 nm.
