    im using the standard what comes with the MB OC profile that takes it to between 4.2 - 4.3 so the standard "Turbo", all MBs in that range should run like that by default, yes I know they are both basically the same chip, it will clock to 4.5 but it would be very rare that I would need it so just leave it at bottom default, the results are the top 50 listed at blender benchmark official site, problem with a lot of the benchmark software is they only use SSE3 instruction sets where as most renders now use AVX (and if I'm not mistaken AMD still don't support beyond AVX 254)

    So when you run a render benchmark all the Cores are running at 4,2-4,3 Ghz?

    Do you have any source that cold verify that?
    Why would render benchmarks use a different type of CPU instruction than the retail version of the software?
    That makes no sense.
    AVX 512 is very much a niche thing at the moment. It will become important in the future but right now its not really a thing.
    The Ryzen 2000 Series was seriously hindered in running AVX256 at optimal speed since the CPU needed to run 2x128AVX.
    Ryzen 3000 supports native AVX256 and it doesnt need to clock itself down like Intel CPUs do when running extensive AVX workloads.

    Hello rustythe1? Are you still there?
    It would be very nice of you if you could answer my first question about the frequency when benchmarks are running.

    A first hint of the new 64 core Threadripper clocks, the new 64core Epyc 7H12 will run at 2.6Ghz base and 3.3Ghz turbo at 280W. Current aircoolers top out at 300W, but a new one from Noctua is support to cool up to 400W. AIO watercoolers can reach 500W.

    yes they are, its set to group tuning,
    according to wiki for zen and epyc based chips, intel instruction sets like avx/sse take two cycles to run on amd and only one on intel, could this maybe be the problem with different softwares?
    also, see here the 9920 and 3900 are about equal, the 9920 just beats the 3900 in turbo, (not bad for 5 year old architecture!)

    and now the new 10nm i7 and i9 released just before xmas has a 5ghz boost on all cores!

    I know it is difficult to ascertain precisely but does this put LW cpu rendering viably back on the table ?

    Oh in that case your CPU is massively overclocked.
    4,2Ghz Turbo Boost applies in light workloads where 1-2 Cores are doing something.
    The more cores are active the lower the boost clocks.
    The standard all Core CPU Turbo Frequency of the 7980XE when under full load is 3,4 Ghz.
    Your CPU is running at 4,2-4,3 Ghz all core. That is almost a 1 GHz overclock across all cores!
    No wonder your results are way better. There you have your answer.
    You compared your heavily overclocked CPU with other CPUs running at stock settings.

    That is a chart with the stock Boost clocks of the 7980XE.

    That is no longer the case with the 3000 Series.

    Are you really pulling data from userbenchmark?
    This benchmark is known in the industry as complete and utter trash.
    Dont trust anything that has something to do with userbechmark.
    Its complete garbage.

    What???
    The Core i9 9900KS is anything but 10nm its still 14nm++.
    The 9900KS has a rated TDP of 127 Watts!
    And the Intel TDP is rated at baseclock which is 4Ghz for that CPU.
    So when its running at 5 Ghz it will use WAY more than 127 Watts.
    Its kind of reminiscent of the stunt AMD pulled with its 5Ghz Bulldozer CPU back in the day which consumed vast amounts of energy.

    Yeah, there is no Intel 10nm CPU for desktops and will not be released this year or next. Just a few mobile CPUs that clock lower (4GHz) but are more efficient, so Intel got nothing new that works, while AMD is really happy now...

    Missed the quote (
    I know it is difficult to ascertain precisely but does this put LW cpu rendering viably back on the table ?)

    Assuming that LW2019 and Cinema 4D R20 (Cinebench R20) both are running "good code" (efficient programming, lots of open source code available to study, so why not). Then you should be able to compare the speed-up in Cinebench R20 for your current CPU and an Epyc or Ryzen in interior scenes. For example an intel 4core 7700k scores 2400 while epyc 7742 64core scores 20600, then the Epyc would render your scene 9x faster.

    https://www.tweaktown.com/news/67586...ors/index.html

    /Edit, guessing both 7700k running at stock 100W and 7742 at stock 230W, both can give more when overclocked (7742 has to be a Threadripper3 coming late Q3 to be overclocked though)

    /Edit2, Threadripper3 is delayed to Q4, more info and good summary here: https://www.cgdirector.com/threadrip...-release-date/

    The 7H12 should go for over $7000. The 7442 goes for $6950. Wouldn't it be cheaper, and more powerful, to get several RTX 2080Ti's, including the cost of an external cage?

    Epyc is the pricier server CPU, like the Nvidia Quadro GPUs that are overpriced workstation cards. The upcoming Threadripper3 should have a better price for desktops. There are very few workstation cases/mainboard for Epycs.

    /Edit, why not both Epyc and 2x2080Ti at once?

    All this can be yours for about $8000 US. (MB, EPYC CPU, and 2x 2080ti, - Newegg.com as of this morning). This doesn't include RAM, SSDs, Bluray, Case, PSU, Keyboard, Mouse, OS...

    A bargain compared to the closest Intel server CPU, the Intel platinum 8180 28core is 10k$, just for the CPU...

    Good news and bad news.
    Threadripper3 24core will launch in November.
    Ryzen 3950x 16 core delayed to November.

    neat, hope it runs on the cheaper motherboards.
