    Scythe! Now there's a blast from the past. Used lots of their fans and coolers 10-15 years ago but then they sort of vanished it seemed. They made great stuff then, glad to see they're still at it.
    As for minimum frame rates, that's all I care about. Nothing annoys me more than random stuttering due to frame drops and such. Max or even average fps isn't particularly interesting if the .1% lows ever go below 60 or so.
    Great video, keep up the good work guys.

    Got a scythe Mugen 5 PCGH for 48 euro, it cools my 2700x way better then the wraith with way less noise. Those Scythe coolers are the best bang for the buck for people that want a silent system.

    Really? I thought this was Level 1 techs, but I must be mistaken. The point of not using all core OC is less power draw and cooler running. You also get multi cores running faster than all core OC when pushed (4.3-4.5) PBO2 is not just a switch to flip on or off. The comparison is similar to the manual vs new auto transmissions. Try a setting of Performance Enhancer Level 3 and a BCLK 102-104 and an offset of -50to75mv. here is a guy who is not a Level 1 tech for sure and he gets closer than this. OzTalksHW

    I really enjoy PBO. It's an ordinary acronym though. We saw 4.2ghz down to 4.15ghz with PBO on the 2700x in Cinebench on the Prism, and some games even hit 4.25-4.3ghz. To say I was stunned with the performance they got out of a 2nm node shrink on that little "box cooler" is an understatement.

      I run a Scythe Mugen Max in my system and I find it does its job.
      Before that I had a Scythe Mugen 4 which was the first aftermarket cooler I bought - it ended up in my second pc when I bought the Mugen Max.
      Always been happy with Scythe coolers and the only time I hear them at all is when rendering videos or running stresstests.

    the hyper 612 is also an underrated cooler. never saw a youtuber ever mention it. its like 2 hyper 212's put together in one single tower (its not dual tower). they are usually about 35 bux and are a great deal. dont know why they dont get talked about more

  • bobhumplick
    bobhumplick 5 months ago

    for gaming i would go 2600x over the 2700 or 2700x. the extra tdp from losing the 2 extra cores can go to more boost. the framerates are about the same. maybe 2-3 frames for the 2700x sometimes. sometimes the 2600x does better. games dont really use enough power on a cpu to matter. thats why rendering needs a better cooler. even with all cores at 100% in a game you might see tops 80 watts of power on an 8 core. when rendering it goes much much higher (maybe 135w or so).
    in games that can maz out or nearly max out 6 core or even 8 its mostly just waiting for comms from another core or something and when its not its just doing logic operations or simple arithmetic. not much avx or sse instructions (although there is some). when a core is waiting for communications from another core it still shows that time as usage. so a core waiting 100% of the time for something still show 100% usage even though its not doing anything. thats why power draw is so much lower on a game than rendering. maybe 30% of that time is just waiting for comms from other cores so they can sync up. also why core to core and ccx to ccx latency is so improtantn

    Direct Touch Heatpipe is just Marketing-PR Nonsense. It does make the Heatsink cheaper to manufacture but cost YOU performance.
    I've talked with people a couple of years back and they told me that a normal COPPER Base that's a couple of Millimeter thick helps enormously...
    Another Thing that's important is if the Heatfins are soldered to the Heatpipes and Heatpipes to the Base....
    How bad the Curveture of a Heatpipe is is also imporant as curveture cost performance...

  • Junker Zn

    But ... is 5% worth an extra 50W at the wall? That number is just a guestimate, you didn't say what the wattage differences were for the three cases (without PBO, with PBO, with PBO+FUMA). I guess it's worth it if its the only machine a person has. Maybe not so much if its sitting in a rack though. I use PBO myself but I actually use it in the reverse... I use it to cap power consumption to lower limits because I have four machines in the rack, including a threadripper (the only machine in 4U), and I don't want to trip the breaker if I just happen to be loading all four of them down at 100% simultaneously.
    I definitely agree with the quiet part. I love those tower coolers when I have these machines sitting in my office. But when I throw the machines into a rack, 4U is kind of a waste of space for anything less than a threadripper. For the 2600[X] and 2700[X]'s, I far prefer 2U cases and more conventional (and noisier) downdraft cooling. The rack isn't sitting in my office, of course.
    There is one down-side to these tower coolers, though, and that is the VRMs and dram don't get much airflow.... the fans are just too high on the cooler. And (I think I mentioned this before), the VRMs and dram (if any) on the exhaust side of the cooler will be significantly hotter than the VRMs and dram on the intake side.

    This is a really interesting topic that doesn't seem to have any attention. RU-clip search for "Ryzen PBO Benchmark" comes up with nothing. I guess everyone just assumes that higher clocks (regardless of how long they are maintained) is better? If I'm not gaining much except a few frames in 1% then maybe I should turn it off and see how far I can underclock?

    Ryzen taught me a lot of things.
    -Memory Timings and Sub timing optimization.
    -A different way to OC(base clock OC with PBO)
    -Different types of RAM. They exposed me to hynix, samsung and micron. before that i thought they were produced by the company that put the heat spreader on it.
    -single rank vs dual rank
    -playing with load line calibration.
    RYZEN thought me how to use the Bios properly.
    I have been an intel User but i could never say that i was educated in computers prior to now.
    Intel just watered down everything and i dont like that. its less fun to OC intel cpu's you change the multiplier and you are done.

    • Blackburn Whiteknight
      Blackburn Whiteknight 5 months ago +1

      Here is the thing. Intel is already fast. Dabbling in and fixing the small quirks like memory timings increases the last 5-10%.
      I had a C16 3000 ram. First ran AIDA64. 52.3ns. Then I did my magic in the bios. At the same CL16 3000 I reduced it further to 47.4ns.
      I didn't get much of a multi-core benefit but I did get some single core benefit ... which is why I got intel to begin with.

    • TheSinisterEyes1
      TheSinisterEyes1 5 months ago +2

      +Conenion it also helps that now i work in the technology field and work with a lot of data sets and programming. Also that is a narrow point of view. Computers aren't just programs and apps. They have hardware which contains more interesting parts of computer knowledge. Like how a micro architecture works.
      In a sense you are correct i became more educated in Bios functions. Not just ram. But that is a whole lot more information than just changing a clock multiplier and voltage.

      No. You're educated in the intricate memory timings of DDR SDRAM.
      You get educated about /computers/ when you study how operating systems, compiler or data bases work (to give prominent examples).

    I wish that AMD wouldn't provide any stock cooler at all. They do a much better job than Intel but I would rather pay $15 less and buy a high end aftermarket cooler and it is a pain in the ass to sell that stock cooler (find a buyer, go to some package delivery company, have it packaged, ship it with signature which makes it more expensive...) even though it has got RGB.

    The 1% and 0.1% lows are more important than most people realize. They tend to look at the max FPS, which is all well and good, but only if it does it consistently. It is the CPU that delivers the frames to be rendered by the GPU.

    • Paul-Sebastian Manole
      Paul-Sebastian Manole 5 months ago

      The 0.1% lows are just too much. A "glitch in the Matrix" kind of spike can make the whole thing seem bad. Even the 1% lows can do that. I believe the AVG is better when taken into account with the 1% low and when compared with others they should be compared like that, with both.

    I would highly recommend the Scythe Fuma-1100 Rev. B cooler for AMD builds. I was definitely impressed with the performance of this cooler for the money. I have been using this air cooler on a lot of builds recently (especially for builds that are using the 2600/2600X) simply because it only costs $46.99 on Amazon and delivers excellent thermal results at that price point. If you're looking for an after market air cooler but don't want to spend $80 on one, this is a great choice. I have had zero problems with all of the copies I have received. I was even able to fit 3 fans on this sucker (get a PWM fan cable splitter of course) when using RAM modules that are not very tall in the vertical dimension.

    I overclocked my 2700X and wasn't getting the results I wanted, then decided to just use PBO on it's own without a set overclock. I regularly hit 4.2+Ghz on all cores while gaming or doing medium tasks althought while under load it tends to clock down to 4.1GHz and stay there (which still isn't bad). PBO is definitely the future and I can't imagine how great it'll be on Zen2.

      +Chris Wright I run the 2600x on 104.4 BCLK. i'd get better single thread with the 2700x in that config though just because of that higher default boost. I am hoping to get something similar for Ryzen 3000

    • Chris Wright
      Chris Wright 5 months ago

      +Grant Dawson I seen alot of videos I know ASRock x470 boards are good it was a mixture of pbo plus blck 103/104 and forgot the memory speeds an timing but I do believe there different levels of pbo cause it will use 1.5v but hits like 4.56

    • Grant Dawson
      Grant Dawson 5 months ago

      its the rev B they haven't sold the Rev A for some time (over a year) being the older model 1000 rather then the rev B with 1100 model number also it says model B on the box but if you want to get a more forceful mount you can shim the springs to get higher mount pressure

All cores are running @ 4.329GHz at load.Edit: max temps with my AIO after 2h of load is 61C avg and 68C max.Edit2: also the cloock speeds that you get on your CPU is dpendant on the load (like Aida64) in my case the manual OC is way better than XFR, also manually OCing my 1600x made bit run on 4.1GHz without stability problems.

    Edit: I like more testing with air coolers : my cooler need to be cheap and don't break.
