[thescarletcars]

I've searched the entire internet for idle power usage stats and found nothing as comprehensive as this. Finally, I can make a decision thanks to you.

[JH_]

So nice to see reviews based on actual work instead of just gaming.

[-opus]

It would have been interesting to see ryzen 5000 cpus included in this, especially considering 12th and 13th gen are included.

[finger]

Everyone is always telling me AMD CPU's are more efficient as I'm sitting here in front of my 2 systems looking at the wattage in real time.
My Intel system while working in Affinity Photo watching this vid and typing this, 11.3W my Ryzen system is idle at 36.8W
Gaming may be another story but real world is... real.

[Real_MisterSir]

This is the exact reason I got the 13900K, it has an amazing balance between low task efficiency, and high task brute force. When I see those 24 cores kicking in my 3D renders I love how much time it saves, but in between renders and between workloads in general, I am so thankful that I can have this beast of a CPU sitting at idle barely sipping power. Over time I reckon it will be even more efficient on a yearly basis than my old 9700K - despite being a latest gen i9 and everyone shouting "Intel power consumption bad!!!!". In reality, my experience is the exact opposite. And tbh nobody outside of enterprise studios sit with render queues 24/7 for 100s of customers waiting in line.

[vx-iidu]

All the time I heard AMD fans saying that AMD is more efficient... turns out that AMD is only efficient if you leave your PC running at full load all the time. (Which is some people, but not most people).

[olibertud]

That's true. Being a creator does not utilize CPU/GPU at 100% always. Thanks for this, I am looking for some irl testing of the software both in idle and stress test. Part of being a creator is thinking and that is an idle time so we should consider that.

[justindressler]

Exactly all that matters is how fast they are because the time saved doing a compile or render is worth way more over a year than a couple of coffee. Probably if you get more done then you will safe money of coffees too while waiting for a task to complete 😀

[rtz]

Glad someone pointed it out! This is why I still prefer Intel than AMD. However, I think the low idle power of intel is because of it being monolithic while AMD is using chiplets/soc, not the best explanation but something like that.

[AirGunWeb]

Very detailed analysis. Thank you. PC World did a similar video showing the same results. I love the analogy of testing MPG at 200mph vs. average use. That was excellent.

Thanks for the data
Cheers

I undervolted my i7-12700K by -120mv and power limit is set to 190 watts. I use FL Studio and it maxed out at 142 watts for a project that used 80-90% of the chip. 60 degrees as the max.

I don't know if my tuned i7 is the highest perf/watt chip on the list.

Efficency goes away when i enable AVX512, system responsiveness isn't the same too without Big-Little.

Motherboard is MSI-Z690 Pro A DDR5, Deepcool Assassin 3, Corsair 5000D Airflow and 32GB Corsair DDR5 4800 (no XMP, just stock).

After i used stock power limits and undervolted the chip, i reduced power consumption by 35% for the same multicore perfomance on Cinebench (almost 23000 points). And iddle power draw is 10 watts with a partial overclock, no core parking, infinite turbo.

[elp]

It would be useful to see the same comparison with the 65W CPUs.

[SaG]

Power draw in all-core, 100% workloads is quite scary on my 14700 KF (over 300W peak), but I totally agree that this is hardly a measure of how the CPU will perform in the real world. Unless all you do all day is run CPU benchmarks like Cinebench or Blender, I suppose.. :)
Power limits on my board are indeed set to "no limits" at the board's factory settings and that's the whole problem. Also doesn't help that MSI have labeled the three PL-presets in the BIOS in a sightly misleading way. Even the lowest preset will set PL1 and PL2 to 253 W and it's labeled "boxed cooler". I'd like to see any Intel stock-cooler keep up with this CPU at those PL-settings, lol. The "no limits" preset is called "water cooler" or something similar, implying that you can run your CPU without power limits on a 240mm (or even a 120?) AIO. Which I could with my much less power-hungry 12600K but definitely NOT with the 14700KF.
All that said: After having read up on the whole power-limit thing, I adjusted PLs, max current and voltage offset manually and the chip will now run right up to the limit of thermal throttling while drawing ~240W max and giving me the CB23 results you'd expect from an i7. All that on a 240 AiO.
In the real world, the CPU never draws more than 40 or 50 W in more demanding games, sometimes peaking as high as 70 to 100W in certain circumstances. At idle and/or in desktop/browsing mode, it's very frugal and hardly ever jumps over 10W. True idle with just a sensor monitoring app open it'll sit at around 3W all the time.

[Lagggerengineering]

This definitely needs to be expanded. Compare DDR5 and DDR4, older ryzen 5000 generations, possibly even 11th gen Intel and CPUs with lower TDPs <65W.

[SarfarazYeaseen]

Have you tried lowering the power consumption of the intel 13th gen processors via bios? Like undervolting, limiting the temperature or manually putting pl2 values? Please make a video on that.

[masterchi]

Great test! I fully agree with the findings. The max power draw is only needed for deciding cooling. For the vast majority of users the CPU is <10% load for >95% of the time, so the low load power draw determines the cost.

[Matty-rngt]

Did you install the latest AMD chipset drivers? They made a big difference on my system for idle power.

[Druac]

Real world testing is where it is at. Benchmarks only show a part of the picture. That being said, I think anyone would be happy with either of the two flagship chips. I'm loving the bump I got from my upgrade this week. Moved from 6th gen i7 with a 1080 to a 13th gen i9 13900k and an Asus Strix 3080ti...OMG! These two parts are working in conjunction with my Z790 Maximus Hero and the upgrade is AWESOME.

[nomars]

I've made a lot of testing with my Ryzen 5600H Laptop to find out its best performance per Wat. Power efficiency depends on max TDP. So it was 15 W for a 50 W processor. Where it has exactly 50% of max computing power but much lower temperatures <50 C, nearly quiet fans, and more than enough power for day to day tasks and even games. Moreover I tested it in multicore cinebench R23 test. But in day to day tasks you rarely use 12 threads. So single core performance dropped only 10%. I used Ryzen Controller app to restrict TDP for normal and boost modes. And I'm happy with results. Dropping TDP lower than 10 W kills performance totally it's just not enough power to function properly for this processor e.g. on 5W it has freezes in all operations and only 9% of max performance. It would be interesting to see efficiency curve for Intel Processors. I believe they shouldn't have such efficiency boost (+50% efficiency) on low TDP.

[uwoluwu]

good job ! I think for CAD work, idle makes up an even bigger percentage. I was allready thinking about buiding with intel because of the DDR4 that I have, but based on this video I think I will be going with 13700K instead of 13900 K. Also needing less cooling means less noise and maybe a smaller case. I swithced to GPU rendering some years ago so more cores does very little for me.
