    Intel counterpart looks like decade old tech looking at scores and TDP.

    They're cheaper and faster but cost a little more to run, looking at the higher TDP.

    I imagine that matters to datacenters.

    Still - overall better from the looks of things

    The IPC looks "roughly the same" between the two.
    52%+ performance for AMD for 60% more cores.

    At this point, Intel is just lacking cores.

    Just lacking cores? I don't think you see the bigger picture here. If it is "just cores" why Intel not mach it or come close? Efficiency also matters for the server market and AMD product is leaps and bounds ahead of Intel's. I wonder what would've been the TDP of Xeons if Intel add 20 more cores. Besides, I've found Intel's TDP inaccurate of what it actually is.

    Not ture at all . Look at performance per watt . For datacenters it is what is most important and at this point difference is huge , just another level . Like i said before , like a decade of performance leap.

    Dude, they get much more work done in the same time, with marginally higher TDP. It's like transporting people with a van, compared to a regular car. Even if the van used 10% more gas, it wouldn't matter since you could move twice as many people.

    What matters is work per watt. And the Cinebench score per watt on AMD's is miles ahead of Intel.

    You need roughly 1.52x more Intel dual sockets to match the AMD score, which would give you a TDP of 410 watts! Far higher with the Intel solution.

    It's more due to:
    - less core
    - less frequency
    - less cache

    counterpart considerating above:
    - The Intel's price make the Epyc even more desirable for a company...

    AMD play well to regain the PRO segment, last week it was aviability of pro GPU, now this...

    Yes and No, it depend on what you do per W and what it cost and gain... If cooling a bit more and it does enough more to compensate this charge it's OK.
    It depend on what the DC is intended to be used to.

    also there's another aspect of having so many cores all in one place: Space savings... can have a much smaller server farm which would potentially save on rent or allow more space for a sea of cubicles or something like that.

    Seems a little weird to me you're not considering performance-per-watt. We're talking a roughly 35% performance increase for a 4% increase in power consumption. This of course is assuming TDP translates to power consumption, which overall it doesn't really, but in either case, the Epyc is very obviously doing more work while using proportionately less power. That's a win for datacenters, where as you said, this sort of thing matters.

    The extra performance also means they need fewer servers, which in turn means a lower electricity bill.

    This^^ AMD´s CPUs are better overall but their biggest advantage over Intel is the core count, if Intel can match AMD on that aspect, then things become pretty even.

    And that´s why i´m amazed that Intel is still to announce something similar to EPyc/Ryzen regarding their multi core approach...

    my experience from comparing a 8c 9900k to 24c 3960x both oc to whatever I could with the same liquide cooling setup (minus the cpu blocks)
    around 1.1x watts for 3x the cores and 2.8x cinebench scores
    intel max temp 89°C amd 67°C (same fans same rads same case !)
    the temps and watt/perf were pretty insane on AMD the only things where it suffered from the comparison were the overall system power usage (all pcie 4.0 and several times the lanes isn't free) and idling power because even if you tune them down there's still 24 of them rather than 8
    with high cpu usage tough the tables reverse and AMD becomes so much better
    can't wait for zen 3 threadripper so i can ditch "I has no lanes" intel

    edit : H83 not only the core count, the biggest problem for Intel is that a single tiny die cannot be cooled properly, amd design helps cooling a lot with my current setup the cpu goes from max temp at 100% cpu usage to idle temp in <1s whatever highest temp was even 100°C so it's not that my loop can't cool it's just that a small surface can't "exhaust" or whatever you call that enough heat

    Good for AMD. Intel deserves kick to the balls for milking customers for years.

    There is one more thing and probably more important that Cinebench score, tech specs or even price:
    Proven reliability.

    Nobody will take a decision to upgrade to a product based on enthusiasm at this level.
    Even if great on paper, will still take some time to prove it reliable for business.

    @nizzen says these CPUs are only good for playing cinebench and they are cheap because they aren't exotic.
