    Wow. Looks promising. But comeon internet....
    I need more rumors regarding core clock speeds . I am craving for grain of salt.

    Maybe it's time to put those salt shakers(or those table spoons if a salt-fre@k) aside boys... Because this is looking better and better. :D


    Never seen that clip of Keem. Pretty funny! lol.

    Let's keep them until benchmarks are out, mkay?

    I hope some review sites plan on testing memory support and performance scaling with Zen2 early on, so we can decide which memory to get. With the new IO chiplet and all, it would be interesting to see if it still loves memory bandwidth so much.

    3200 with a good latency used to be the sweet spot, but if the RAM support has improved a lot, maybe getting a higher module is actually a significant benefit now. Would love to see some tests when its time!

    Do we know if Zen2 (ryzen 3000) has a custom made IMC from AMD or it is a purchased design from 3rd party as with Zen and Zen+ ?

    Considering how heavily integrated it is with InfinityFabric and their iGPUs, I would assume it's an in-house design.

    The reason for this is if they ever release 12 and 16 core part, it is going to chock with dual memory channel. That's why I claim that Intel 9900k will still beat both CPUs in gaming regardless what AMD does with memory.

    Wrong. AMD's IMC was already at par with intel's in initial Zen.
    Memory intensive workload for up to 8C/16T will behave exactly same and it will be IPC that will decide performance.
    For workloads using more cores/threads, IMC will matter, but it will still do better than just 8C/16T unless IMC is saturated even prior using those 16 separate threads. But then 9900k would choke in same manner as their bandwidth is quite comparable.

    Most of the workloads are really not that memory intensive. CPU is not GPU.

    Personally I don;t care if Intel will still be king ! But I would really like to spend my money wisely .

    Except that it OCs like crap, of course.

    True but it was because they didn't give a seperate clock modifiers. With Zen2 you will have MEMCLK, FCLK, and UCLK to tweak. With zen/zen+ these shared the same clock domain and it put to much stress on the IMC and Infinity fabric.

    MEMCLK External memory clock
    FCLK Infinity fabric
    UCLK Clock speed of memory controller (can be set to MEMCLK or 1/2 MEMCLK)

    And on that I also assume that we don't actually need fast memory to have a fast Infinity Fabric?

    Correct. Right now in the current BIOS'es the IF clock can be set from from 333MHz to 2100MHz independently of the memory clock.

    This is a great confirmation that the crown of "gamer" CPU of blue side is falling down! With sure the ZEN2 will run 4000MHZ with nice latency and with the @ 5.0GHZ on all ZEN2 CORE will SMASH Intel! And the better.... MORE CHEAP!
    It´s probably that, disable the 16 threads, the 8-CORE with nice AIO cooler and thermal paste will hit 5.2GHZ.
    Prepare yourself... the green times are coming!

    3.2GHz with 4 sticks and 3.6GHz with 2 sticks is far from crap.

    And with DDR4 prices almost back at June 2016 levels... 80 bucks for 16GB instead of 190 :D

    Yep, way more sensibly priced now.

    I'm not so sure. Zen 2 has twice the amount of L3 cache as Zen, and that will make a huge difference as more data can be kept closer to the CPU. Also, most desktop applications are not bandwidth intensive enough to really be crippled by dual channel; especially if its high speed memory.
