    AMD is paving on that processor road hard. The recent Ryzen 3000 series processors have seen a pretty bump in nice instructions per clock (IPC) improvement wise that is, and that is about to happen ag...

    I hope this is actual IPC gains and not overall performance gains. If that is the case and we see a 10% IPC gain with say a 5% clock boost then the next Ryzen generation will be amazing!

    As long as these CPUs are compatible with latest X570 motherboards they might be an upgrade option. If it’s new motherboards again then forget about it for me anyway.

    It is already known that Ryzen 4000 series will work in X470 and X570 boards with future BIOS updates.

    Actually, I think AMD said that this gen will be the last on the AM4 socket it is 7nm tech and not 7nm+ and I think it will require a new socket.

    Zen 3 is the final gen for AM4.

    I want 4SMT's per core but i guess thats Zen4.

    I want way lower latency. Under 30ns:D

    Low latency AND high corecount is the future ;)

    That's not it m8.
    The best source we have is a slide with the next Epic (and Zen3), clearly states PCIe gen 4 and DDR4.
    New socket will probably come with DDR5, and that's due for 2021.

    That large unified cache should by itself be enough to raise IPC by a few percent.
    Add a few tweaks left and right and 10% is definitely possible.

    As for the clocks... well, something went wrong with the production of current Zen 2 (it got delayed.... twice), and still barely any higher clocks than Zen1 +
    Apparently this first 7nm round wasn't as good as expected.
    But with almost one year of further developments, it should definitely do much better and make 4.5 Ghz and up commonplace.

    Well Zen3 is not announced yet, could be 2021.
    Support could also just mean driver updates, security fixes, software improvements. Not commitment to keep CPU working on the same motherboards.

    Nice one. Now if they can increase their clocks then Zen3 is going to be a little beast!

    Thought we were on AM4 until at least 2020...?

    I highly doubt it. I'm still betting that the Zen2 APUs will be the last we see for AM4. Watch AMD's release cycles and it doesn't make sense why Zen3 would be for AM4. At the rate they're releasing products, it wouldn't surprise me if the Zen2 Ryzen 3 products are released in 2020 as well.

    That implies nothing about Zen3.

    2020 is 11 weeks away, and Zen2 didn't even finish launching yet. 2020 is approaching fast. A CPU thats rumored to launch Q4 2020, and possibly push into Q1 2021 seems to be even borderline on that definition, and I wouldn't be surprised if they change it to a new platform - which is ultimately a good thing as well, since backwards comaptibility for 4 generations of CPUs might start to hold it back.

    If the rumors are even remotely accurate, there are no significant changes in the structure of the Zen 3 CPU to worth changing the socket:
    - Still DDR4 dual-channel
    - Still 8-core chiplet(s)
    - Still PCI-e 4.0 (just launched, duh!)
    - Same USB 3.2 Gen 2 controller on-die (aka, USB 10gbps); Maybe the new CPU will also support the 20gbps version.

    What they are doing is improving the internals, like unified cache instead of independent CCXes, and probably Zen 3 will support higher IF speeds (also an internal thing).

    If they move away from AM4 for Ryzen 4000 that would simply be a dick move à la Intel.
    Technically even B350/X370 could support what Ryzen 4000 seems to bring (which is simply an improvement to the current Zen 2 design, nothing revolutionary like Zen 2 is), if they chose to.
