AMD Ryzen Frequency Scale - Temperature is Important for Ryzen 3000 CPUs

This video looks at AMD frequency and cold scale with full stock settings, using only Precision Boost 2 (NOT the same as PBO) and controlled temperatures.
Support GN via the store!
In this video, we manually manage temperatures between +84 degrees Celsius and roughly -80 degrees Celsius, showing incremental steps along the way to demonstrate cold scale. The end result is that we can learn how frequency behaves versus temperature on AMD Ryzen 3000 series CPUs, focusing most on the new R9 3900X (but also relevant to the R5 3600 and R7 3700X, etc.). The end result is that better coolers and better airflow cases will improve bottom-line performance, and so should be factored into component selection.

    • So basically it's auto 'overclocking' as long as your thermals are good (like you would make sure if you were manually overclocking) and if not it's doing the best it can with the thermal situation it finds itself in. So instead of just maxing it until it gets too hot and needs to dial it back or do an abrupt shutdown, it scales it's capability with the live real world conditions it's facing. I actually like this, it does the best it can with what it's got to work with ramping up and down as needed, instead of enforcing a certain high or max setting which is not taking into account the thermal situation it's in until it's in a bad spot and needs to react to it. It will live and breathe in it's environment getting a feel for it and dealing with it accordingly. It is an improvement I think and makes the chips smarter and reactive to the real world rather than expecting to run optimally always which in the real world isn't always the case so in this way it adapts to it's environment. :D

    • Motherboards are 30-40% more expensive than Z390 motherboards. And this video says exactly straight that - to get boost working as expected you need better cooling.

      cothcoth4 หลายเดือนก่อน
    • So , you tell us how much of a consideration cooling should be on Ryzen 3000 while at the exact same time hardware unboxed puts a video out telling us how little cooling matters on Ryzen 3000 . Nice going guys , now iam as confused as a confused thing in the dark .

      MrColinbradburyMrColinbradbury4 หลายเดือนก่อน
    • @coth The motherboards are no more expensive than their Intel counterparts. Also, AMD needs LESS cooling than Intel parts. Try again, cuckboiii.

  • Is it normal for one core on my 3800x to like 20c warmer then the rest, when i do all core stress testing that core is like 75c the rest are all 55c.. seems weird to me

  • Too bad my room is always hot, with 240 gallons of fish tanks, and being in the 3rd floor of my house my ambient is always really high lol.. My cpu is usually at 4180-4200 all core on my 3800x, but in games its usually only running 2 cores and they tend to jump around 4200-4400mhz. I have never really seen 4500mhz on single core benchmarks, i might see 4516 for a blip of a second but usually its like 4486. Im using a duel 360mm radiator setup, and a EK water block with 2 reservoirs, but i also have my 1080ti on the the loop, but the 1080ti is after the cpu. With 6 fans on my radiators. With room being like 76-80f usually id say this isnt bad. If i open the window and it is winter time the room temp will drop around 72-71f, and i might get 30-40mhz more over the 4180-4200 but thats it. And to be honest 50mhz, even 100 mhz doesnt really do much for fps, the gpu like he said is the biggest upgrade one can do, or memory tweaking, increasing the fclock on the cpu to 1866 gave me over a 10fps improvement in some games. to where 100mhz on the cpu did almost nothing, Ive probably spent a good $600 on my cooling setup but it really wasnt to get the BEST temps i could, it was mainly for looking and more consistant temps then air cooling. Plus watercooling my 1080ti lowered temps from the 70-80c range to more 40-50c. Now that 1080tis are about 400$ used, i suppose i could probably get a 2nd one, and another water block for it and do SLI, but i dunno if SLI is even viable today anymore

  • Good vid. I've been able to get my 3700x to 35c idle @4.4ghz all core by disabling pbo and changing volts to 1.3. I'm using a deep cool maelstorm rgb 240mm aio for cooling and it seems to be doing a good job.

  • running a 3600 on baseclock with default cooler on and it seems to struggle in idle boosting up to 4,2ghz and reaching temps of 66 degrees on desktop. Anyone any advices on this?

  • "3000 CPUs" but you show only 3900X. Not everyone will use air conditioning due to power cost and I have higher ambient temperature of 35C+. If its getting too hot I will have 9700K instead 3700X.

  • I’ve studied physics at the university. Why haven’t Pc companies utilize black body radiation theories to keep the Pc cool? You can have a cavity absorb all the radiation, and emit it elsewhere. Like a mini black hole

    • It will be hot anyways, I have the 3600x and it runs on auto from 4.2-4.4ghz. I think these cpus are meant to run really hot, but I recently got a AIO Liquid Cooler from Corsair which dropped my gaming temp from 66-70C to under 60C

    • My 3800x is around 58-65c depending and im using an EK water block, plumbed into my 1080ti, into two reservoirs "for show mainly" and two 360mm radiators. My water cooling setup is just mainly for looks though althought it did drop my 1080ti from the 70s to the 40-50s. But yea and my room temperatue is usually 80f thanks to being a tiny room with 240 gallons of fish tanks and on the 3rd level of the house.. So yea its easy to get below 80c all cores..

    Target -DroneTarget -Drone4 หลายเดือนก่อน
    • A 212 would do fine. But if you're not looking to break the bank, and want to maximize the chips potential, grab an AIO water cooler. These chips really do their best on any form of water. I'm on custom water I've had since 2006, it's not quite as good as more modern water blocks, but it's comparable to the best AIO's, and it does show up in benchmarks. Either that, or go with a 212 and invest in the best RAM you can afford, because you'll likely get more performance from fast RAM than you will water cooling.

  • As an engineering student it's really hard for me to watch some of these charts on otherwise one of the most scientifically accurate review channels. 10:14 being a perfect example. 1. 90% of the area is completely unused and the real plot trend is effectively non-existend on this chart. 2. The effect of gradually plotting the chart in time is cool but discrete data measurements are rarely being connected with a linear (or spline) interpolation as it implies that you have perfect knowledge of all the infinite continuous values between measured data points. It is usually more accurate to use a point chart with a trend line approximating these values. Something like this would be more scientifically accurate though still not ideal: The equations and trend lines here would also be debatable since it's not representing a mathematical prediction from physical theory and I guess you don't have a specific trend (ex. from a data sheet) that you are looking for either. The reverse X-axis is also hard to swallow but I get the reasons.

I've done lots of testing over the past week or so. I have a 360 aio and I'm getting clock speeds of 4625 on a few cores 4650 on a few and on 3 of my cores they have maxed out at 4675. I haven't seen any other stock cpus hitting that. Anyone else having their cpu hit that high on stock?
