Ryzen Master is probably more accurate right now. NZXT is still having some issues tuning the temp readings on Zen 3 (but at least it can be detected now), but is working on it for a future update to CAM. My z63 is measuring a similar 10 degree difference from Ryzen Master too. Answer from Angelic_Jin on reddit.com

r/Amd on Reddit: Core temp and Ryzen master displaying different CPU temps ?
March 30, 2020 -

Which one is more reliable ? Ryzen 9 3900x with stock cooler Core temp is saying mid 50s to 60s at idle Ryzen master is saying low 50s to mid 50s idle .

Thanks!

Ryzen 3700x wrong temperatures shown - ALCPU Forums
August 4, 2019 - I just recently built a Ryzen 3700x system and have been using Core temp since my AMD 8320 build. I've noticed that the temps are reading 10 to 15 degrees hotter showing 40-50c on idle, vs Ryzen Master, which averages around 32-35c. I also noticed that the power consumption is not being read.

[SOLVED] - cpu temperature different in HWmonitor and Ryzen master | Tom's Hardware Forum
February 23, 2021 - Ryzenmaster reports an 'average' temperature that levels off the thermal effect of the spikes. That's the more accurate thermal condition of the CPU. One utility has both so you can compare them: HWInfo64. It's very useful when you create a graph on the desktop to show how they compare across ...

Are Ryzen Master temps accurate? - Quora
Answer: Depends who you trust. Ryzen Master is currently reporting my CPU at idle clocks (most cores are inactive with 2 at 600MHz) and using about 0.6v with temps of 40c. HWMonitor (a highly regarded monitoring app) is currently reporting all core boost to 4.2GHz, voltage is 1.2v pinned and te...

AMD Ryzen 5900 - What is most accurate temp monitor? | [H]ard|Forum
April 9, 2021 - I'm a bit confused as after some googling I get some people that say that Ryzen Master is most accurate hands-down because AMD has some proprietary way of reading the sensors (Just repeating what I've read, I have no idea about that and am not making the claim), others say to stay away from Ryzen Master and use HWInfo64. Some swear by HWMonitor and others say its less accurate. So I'm not sure which utility is the most accurate? ... Ryzen Master or HWinfo using "CPU Die (average)" should give the same readings, and are the most accurate for Ryzen CPU's.

r/Amd on Reddit: Most accurate software to measure temps for 3700x?
August 14, 2019 -

I have been trying to figure out the temps on my 3700x but that seems to be quite the task since every software I try gives different readings. I have tried Ryzen Master, HWInfo and HW Monitor. Before I try Speccy I thought I'd ask what software is the most accurate an reading temps.

The problem is that Ryzen Master report idle temps at 35-37, HWINfor says its 30-33 and HWMonitor says its 39-41. It gets even crazier under load. In Battlefield V RM says max temp at around 70-73, HWInfo ended on 65 and HWMonitor went all the way up to 80.

I'd like to think RM is the most accurate considering it comes from AMD but I dont like the software since I cant seem to get a log saying what max temp is and when alt tabbing the temp do change a few degrees so I have no chance to get the correct max temp. On the two others it says Max temp so I do not need to alt tab all the time trying to find where the cpu ends up. I have kind of ruled out HWMonitor since the case fans doesnt go up to 100% when HWMonitor report 80 degrees.

So anyone have any idea which software really is the most accurate?

And are there any way to get a log out of RM?

October 1, 2019 - CPU (Tctl/Tdie) in HWiNFO should be the immediate hottest temperature in the entire CPU package, while the CCD value covers only the CPU cores of a given Core Complex Die (CCD). Based on our measurements, the CCD value should be closer to AMD Ryzen Master reported temperature.

r/Amd on Reddit: New Ryzen master temperature lower than other monitoring software
August 1, 2019 -

Hi,

I've a 3900X on a MSI B450I motherboard. Yesterday night I had my fans ramping up and down constantly. I use CAM (little dissapointed by this software but that's another subjet) and had ryzen master and hwinfo open. After a couple minutes of observation I can tell that ryzen master show a temperature in a 5-20° range LOWER than CAM or hwinfo.

CAM and hwinfo are within the same 0-5° range that can be explained by the time the sensor got probed however this cannot be an explanation for ryzen master. It sits for long period of time like 10° lower than any other tool.

So what are you guys seeing ? Is this an MSI bios offset issue or did AMD tweaked their temperature sensor in ryzen master so that it shows lower temps ?

CAM 3.7.8

Ryzen master 2.0.1.1233

HWInfo 6.10

Edit : Info in AMD PDF :

For temperatures:

• OLD BEHAVIOR: Report the highest temp (“instantaneous temperature”) of any sensor in the whole CPU, no matter how isolated or brief. This approach overstated the prevalence and significance of fleeting peaks, which artificially inflated temperature reports by up to 30°C above the true silicon conditions.

• NEW BEHAVIOR: Report a short-duration rolling average of all temp sensors in the chip. This model will give you a holistic view of what the processor is doing across cores, cache, bus interfaces, etc. It’s the closest any software monitoring tool can come to portraying the true thermal conditions of the chip, and it’s the same model our own Precision Boost 2 algorithm uses to make temperature-related boost decisions.

ADDITIONALLY: We also intend to release new developer documentation that enables third-party tools to take the same measurements, so you can continue to rely on your favorite third-party apps after they’re updated. We will be contacting utility vendors directly with more details when the documentation is ready.

Edit : to be clear, exposing a problem and being picky about it does not mean I shit on AMD. The CPU is great and a huge upgrade from my previous one. I just feel they need a new team (or add new ressources if it does already exists) that work on integration at all levels (bios, software, behavior etc) so that we don't get a shitstorm at every launch. We often talk about brand image, those launch pretty much hurt it.
