    No, I just separated Cores and SMT threads to better understand how each application scales. For example, it doesn't look like Destiny 2 uses SMT at all, only cores:

    Tested UE4 lightmap building with a simulated 1600 (3+3 from the BIOS with 2 cores deactivated) and the 1700. Pretty good bump, every setting was the same except core count:

    I've also enabled this from the experimental settings:

    So in other words, add enough cores, and your level is finished rendering before you even design it? :p

    Just got done building a new Ryzen system, 1700. Have the CPU running at 3.9, and memory at 3600.
    I can get the CPU to 4.0, but then for some reason the memory downclocks.

    EDIT: set the memory to 3466 MHz, CPU at 4.0, temps do not exceed 63 C in prime95, or Handbrake.

    That sounds like Assassin's Creed which was supposed to be a Prince of Persia but was secretly turned into the game we know now. ^^
    Management should trust some of their people more.

    Actually no, it doesn't. We don't know how many possible "skunkworks" ideas there has been on the GPU front, not before one becomes huge success, they won't tell about them without that part

    Eyefinity comes to mind on GPU side.

    Article is paywalled, are they saying there had been no plan for 16 core version of Epyc? Or just that some engineers took that & messed with desktopising it.

    Maybe there had been no plan for dummy cores.

    Doesn't 16core EPYC still have 4 Zeppelin dies?

    The latter. There was a free version of the (same, entire) article I read it somewhere, but now cant find it anymore.

    Yes. All Epycs have 8 memory channels and 128 PCIe lines (some reserved for chipset tho.)

    I was pretty sure that was the case. That's why I didn't understand the connection between Epyc and 2-die Threadripper.

    The biggest different is the marketing department, recently AMD radeon twitter account said there were 570 on stock and on "great price" of 280 dollars....Even I had to comment asking what was wrong with them.

    The architectural features that allow Ryzen to connect four dies allowed them to link two dies with comparatively little effort. While they were at it, they reused elements like the general socket format from EPYC, which likely explains why Threadripper inherited the mechanical requirements of having two placeholder dies.

    It would have been harder to get preliminary work as far as it did if the overall architecture needed changes and real investment, made the business case harder once presented, and it would have taken longer to roll out. In corporate terms, it was more spontaneously put together than EPYC and Ryzen because Threadripper naturally falls out of the system's capabilities.

    Yes also the timeframe given to show the project that were originally planned for 2018 and was moved a year to make the 2017 launch with in my opinion was the real game changer. Now that TR exists and its selling as good as it can be we can be sure of more refine design in the next generation, probably moving to a unique platform to make it easier and even cheaper to work and manufacture.

    Its really rare to me that AMD didn't plan TR from the beginning since they were working on Epyc, TR just look like a natural path to me. Im exited to see how the next gen will look.
