    What I don't get is how that CPU can be stable at that voltage. Shouldn't quantum tunneling be a major issue for this?

    I'm not even a water cooling fan, I hate these articles about LN2. Why should we care how much a CPU can OC in LN2, will anyone run a setup like that at home? I never understood the fuzz about it.
    OC with anything using Air or/and Water and I'll respect the results. LN2? Get lost.

    Reducing the temperatures so much fundamentally decreases leakage.

    I would still think the CPU is pretty much fecked after all the benches are complete.
    There would still be some migration, due to the insane voltage and speeds involved, even at low temperatures overall.

    some chips go a while I had two 3770k/3570?k's on ln2 or dry ice every week for about a 1 and a half years both still had max air clocks.i think the board I used saved them by voltage safety crap kicking in lol
    on the other hand the 980x were very weak ln2 was certain death it was just when.1 I had was sooooooooooo hurt after 3 ln2 sessions

    @las and others:
    do you see super sports cars compared by how how long it takes them to go from LA to SF in stop and go traffic, or by timing a lap on the nuerburgring?
    right.
    even if its doesnt translate into any real world use (perf/cooling etc), its a good indicator, and allows to compare to intel running a similar setup,
    as well as showing some ppl (that dont have a lot of processing power themselves (grey matter), that intel isnt the only viable option anymore.

    same for tweaking.
    the days when a few ppl would get crazy oc on cpu/gpus are virtually over (outside compressor/LN2 cooling etc)
    manufacturers want less possible issues and limit stuff (e.g. power on nv cards), and making stuff smaller doesnt help either.

    sure im not that happy that manual tweaking wont be as rewarding as it was years ago, then again it was a bit more lottery to get a good chip (going past the common +10%),
    vs those kind of "guaranteed ~10%" we see today, but at least now i dont need to spend all day running benches and doing multiple reboots to find clocks that are stable.

    with the oc scanner it took less than 30 min to find clocks (+79 MHz) very close to my max stable clocks (+85), while using less voltage (1080)

    So, you're doing this?

    Who says it? You? I see that 2060 is 30$ less than an RX5700 while being 10% slower and having 2GB less VRAM and the 2070 is $50 more expensive while being 10% slower.
    And AMD can lower prices if they need it. The rumored $100 NV price drop might remain a rumour too. And first wait for Navi reviews than the "super" reviews.

    Which is great, except, it's not 16 cores. Get an intel 16-core processor to 5.1Ghz on water, then you have something to talk about in regards to this news.


    Not sure anyone expected 5Ghz on AIO or air for 16 cores.....if anyone did, that's just crazy talk.

    200 MHz extra on all 16 cores equals to a 3200mhz more to use for the system, its like having an extra CPU, no wonder heat goes up so much!
    Can't wait to see how the 8 and 12 core models behave

    So 4 cores Ryzen would hit 5Ghz+?

    Does it happen?

    Why clock speed goes up the more expensive CPU gets, regardless of cores count? Amd marketing trick??

    Is "under water" above the surface?

    Anyway, just chill. It was a joke/pun.

    I don't understand what you are asking.

    To me, you basically just asked why CPU companies create products, as CPUs tend to get more expensive as the default clock speed goes up.....this isn't special to AMD, so i don't understand your question.

    Also, what 4-core Zen 2?

    I am just disappointed that lower price models can't be overclocked more than higher cores count CPUs.
    Why? Cause then higher-end models won't sell well.

    So if 16 cores CPU can't push 5GHz on standard cooling, means lower models probably also not achieving it.

    I don't know if AMD cripples cheaper models like (3600), so it doesn't overclock over 5GHz or there something else to it.

    Code:
    CPU    Cores / Threads    Clock speed/turbo (GHz)    Cache (total)    PCIe lanes
    CPU+x570 chipset)    MSRP
    Ryzen 9 3900X    12/24    3.8 / 4.6    70MB    40    $ 499
    Ryzen 7 3800X    8/16    3.9 / 4.5    36MB    40    $ 399
    Ryzen 7 3700X    8/16    3.6 / 4.4    36MB    40    $ 329
    Ryzen 5 3600X    6/12    3.8 / 4.4    35MB    40    $ 249
    Ryzen 5 3600    6/12    3.6 / 4.2    35MB    40    $ 199

    Don't know where you're getting that information.

    18-core intel CPUs can't OC as high as their 6-core 9900k etc.

    Again, nothing new here.....

    I am not talking about Intel, I am talking about AMD here, Ryzen and Matisse line up to be specific.

    Again, your post makes no sense. Intels higher-core CPUs can not be overclocked to the same ability of their lower-core parts, and i don't care that you're "not talking about intel", what you're stating doesn't make sense and can only be compared. The higher core counts you go, the lower OC headroom you have with "standard cooling", this is factual, so again, where is your information from?

    True, it's applicable for both AMD and Intel, the more cores you have the greater the chance you will have a single core within the CPU that falls short of a specific frequency at which point the CPU will become unstable., so a 8 core CPU has a greater chance in one of them cores failing to keep up with the speed of the higher clock cores which if you run prime95 you can determine which one it is... so long as it doesn't blue screen or hard lock.

    I am pretty sure binning the chips is something that every company that produces chips does not all cpus that come out of the same even waffer are equal! That's why we have silicone lottery, and about oc in amd cpus i do not think they will limit it at all but we will see HH will break those puppies in the review!
