Why does a I5 10600K run cooler than a R5 3600.

[redcan0]

Hey everyone, I have a friend who has the same case and cooler as me but I have a Ryzen 5 3600 and he has a 10600k. Even though the TDP of the 10600K is a lot higher than the R5 3600 he gets a lot lower temps. Also his idle temps are around 25 degrees while mine is around 36. His power consumption is generally lower than me. Is this due to the inefficient architecture of Ryzen? Does anyone know? Thanks.

Are you using the same cooler. Also how cool does it run under load?

My Ryzen 5 3600 is running at 1.1 voltaje 4.2 GHz.

His 10600K runs at 4.5 GHz everything at auto. He gets around 6-7 degrees lower.

 

And yes we both have the same AIO cooler

Idle temps at 25C?  That's ridiculously low.  My guess it something isn't being measured properly.

 

That being said, a LOT of things can affect temperatures.  The case you're using, the fans, the way you installed the cooler, the thermal paste you used, and more.  You also can't just compare TDP on Intel and AMD, since they're calculated differently.  36C at idle is fine though, nothing to be worried about.

He uses a Silverstone PermaFrost 240mm AIO

I use the same AIO but 360mm version.

He didn't change anything in Bios in terms of voltaje and clocks. But I don't know how he gets that kind of temps.

 

I also checked the power consumption while his CPU was idle and it was around 19 Watts.

My CPU takes 40 Watts while idle.

Could this be the reason?

Why does my take up so much power in idle?

See the edits I made to my last post.  On top of what I already said, "idle" is not really defined.  Your CPU is always doing something.  You don't have anything to worry about.

idle temps and power consumption don't really matter. you should only compare load temps and power.

power consumption can only be measured accurately with a power meter inserted in the socket.

getting 25c at idle is not possible, unless the ambient temps in your friend's room are less than 15C.

make sure you both use the same software for monitoring temps (hwinfo64 is the most reliable)

Coincidentally I just built a 10600k system yesterday, and without doing side by side tests I think it runs cooler than my 3700X system, both at stock. I think it is not unexpected. The 10600k is rated at 125W TDP. In the system I just built running stock, the reported power running Prime95 small FFT was stable around 130W with the CPU going at 4.5 GHz. Ryzen 65W TDP CPUS, like the 3600 and 3700X actually limit to 88W PPT at stock. So yes, the Intel CPU uses more power in that scenario, why isn't it hotter? Simply, it is much bigger. Temperatures have been a problem with Zen 2 due to the much smaller process used, leading to more heat density. The total heat might be lower, but until it manages to spread out it is more concentrated into a smaller area.

This was really helpful. Thanks.

Idle temps don't really matter, and the way Ryzen CPUs tend operate with boost frequencies/background tasks, they appear to be hotter than Intel systems. 

 

Additionally, the 10600k has a revamped IHS/DIE that helps thermals tremendously over the prior generations.

 

There's also a lot of factors such as ambient temperature, GPU used (this can greatly affect CPU temps if your GPU is some heater) as well as case flow and cooling capability.

Transistor Density. The 3600 has more gross transistors. I/O is probably a large portion also. 

 

3600 may run peak and idle temps higher, but with much better efficiency.

 

3600 max temp 95c throttle

10600K max temp 100c throttle.

Both shut the board off between 110-115c

+/- 5c depending on the bios.

Thanks. I thought my AIO was broken or something when he saw 7-8 degrees lower than my R5 3600.

 

Btw, I can use my R5 3600 at 4.6 GHz with 1.45V and I face no heat issue. However, 1.45 is a high voltaje.

What would happen if I use my CPU at 4.6/1.45V at daily?

 

And I am planning to swtich to a 5600X

Was this Transistor Density thing improved for better temps?

Honestly, currently I get 37-40 degrees idle at 1.1V and everyone around me gets lower than that. Even though idle temps don't matter that makes me upset

Really you should keep the voltage closer to the FIT regulated which is about (on average) 1.3250v for all core loads.

 

At 4.6the and 1.45v would probably face rapid degradation of the processor, time line of life unknown.

 

Most average processors have a life span of 100,000 hours when run at default settings. Using a high voltage can cause damage and this doesnt matter the temps above ambient.

 

The goal with any overclocking varies, but generally the faster you go and the more voltage you use, the cold the cpu temps should be. At 1.45v, sub ambient loaded core temps would be a keen idea.

 

They didnt improve temps necessarily with Ryzen 5000, but they did improve the IPC greatly near the same wattage used.

 

So a cpu running 85c at load (for example) being at stock settings is a non issue and would last a long time either way.

 

You can get low idle temps by running green and let the cpu acquire its lower P-states. A manual all core OC kinda eliminates low idle temps. The stock XFR also can produce high idle temps. But is perfectly normal. 40c idle is pretty fair IMO.
