    I thought we would see 5nm cpu in 2022 but after reading up on it people (internet) seem to think it could be 2021. Is that really the case? Are we really moving that fast? If 7nm is bring 64 Eypc cores would 5nm bring 128 Epyc cores?

    Just wondering what we can expect in the next 5 years.

    Don't know, if you figure it out, buy a lotto ticket.

    128 cores @ 6 GHz

    Meanwhile, Intel will announce 14nm++++++++++++, promise 7nm parts soon, and launch 3 unnecessary socket changes.

    5nm is just a naming. For instance TSMC 5nm will be equal and not better than 7nm EUV Intel or Samsung. 7nm TSMC is lower tech than 10nm Intel, which is why Intel is struggling.
    Intel announced he will build 3D chips and that will happen before 7nm. Meant to happen on Intel GPU, not sure won't happen on Intel CPU.

    Yeah well Intel can hold themselves to any higher standard then what we have seen without releasing any details (they are really good at it too, you know lacking yield information).
    If you peel the naming convention of the process then what is the step that will be the improvement that people can expect from the silicon at the "5nm" process compared to what we have now.

    And that is something no one knows exactly the process can be a dud like 20nm was or run into trouble (where Global Foundries needed to pay Samsung for their 14nm process because they were not getting anywhere).

    As long as the process is stable you can expect improvements but the lower you go the harder it gets. You can dig up some of AdoredTV youtubes which explains this a bit better.

    Sadly, the "nm" number is really close to meaningless. It's not an actual consumer metric, so I don't understand why consumers would care.

    As always - compare actual results. Power versus watt. Max power. Etc.
    The "7nm" chips from AMD, regardless of actual chip geometry cited, look to be solid. If Intel releases something which bests it, we'll be interested in that too.

    For users, you really should not give one flying f what number is listed on some process node. That's irrelevant. Can you get the performance you need, within a power envelope you require - that's what matters.

    Well, it sorta matters if another company uses the same node for a similar product (qualcom and samsung for example, if they both made an arm processor on tsmc 7nm...ignore that samsung probably would never do that).

    Only if the end result was meaningful though - right? That's all I'm getting at.

    Yeah, I mean you'd still want to run the numbers to figure out which is actually better, but it can give you an idea of the theoretical potential of a product before it's release, when benchmarks aren't available yet...assuming they use the same (or a very similar) node.

    7nm is going to be a LONG NODE we wont see 5nm for 3 to 5 years as tsmc is building that new fab for it

    I can't believe we are already at 7nm. I remember the excitement around my then office when the number before "nm" went from 3 digits to 2 digits...

    Well, I don't know much about nodes and the technology. Others do. I guess my question is if TMSC 7nm node doubles the cores as we are seeing now would a drop in another node double it again? Then again at 3nm? It seems like things are moving fast now that intel can't milk shit for years and years now.

    Ps. Chesebert your old as fuck dude...Well, i'm 37 can't really talk
