Power consumption and efficiency in gaming: AMD vs Intel
The difference about GPUs is that you can’t have 4090 performance at 100W. Not for the next few generations at least. But you can have top performance for gaming at 100W, how justify the 250-300W?
99% of the time my GPU is at 200-220W, CPU 70 ish W at most.
But the 360 AIO as requirement to avoid thermalthrottle if left at its own desire is poor. Intel could be 5% slower at same power. Or same performance for 5% more power. But as it is, not worth for gaming at least.

If I offest the v-core any lower it starts to get a bit unstable.

Sorry to resurrect this thread but it is pretty useful.
Looking at an UNRAID setup to use a setup with decent NVME support I will need to go for a non embedded CPU + with a decent integrated iGPU.
It looks like the i3-13100 or i3-14100 fit that bill + have the low idle power consumption. Is there a comprehensive comparison of idle CPU power consumption anywhere about (I have looked).
(I actually have the option of a cheap 5700G which might fit the bit going by the OPs video), it just doesnt play as nice/as powerful for Plex transcoding.

hwcooling.net did an article here on the difference between the two 12400 versions:
The same and yet different. Intel Core i5-12400 duel (H0 vs. C0) - HWCooling.net
Core i5-12400 SRL5Y and SRL4VWe have a shocking revelation! And now, seriously. Different Core i5-12400 processor steppings differ not only in S-Spec code, but also in behavior in practice. Some of the expectations were confirmed, some were not. More importantly, you can choose the more suitable...
www.hwcooling.net
computerbase.de often includes these numbers in their reviews:
Intel Core i5-12400 und Core i5-12500 im Test: Leistungsaufnahme, Temperatur und Overclocking
Core i5-12400 und i5-12500 im Test: Leistungsaufnahme, Temperatur und Overclocking / Overclocking: Über den BCLK auf DDR5-Boards möglich

Historically ASRock has been pretty good, Kontron are probably better, high-end motherboards are usually bad.
Ryzen CPUs have higher idle power consumption with XMP/DOCP enabled and/or memory above 2666. I believe 12th-14th gen also have this issue, but I haven't seen much testing on it.
Threads like this can be helpful, but you have to dig a bit for the info you need. NAS forums are generally good sources.

Comprehensive response thanks! HWcooling testing v useful.
Wow fairly big changes between Intel Core i3-14100F, i3-13100F and i3-12100F, with the 13th gen coming off far better.
Will dig around some more as you say.
EDIT: Pretty great idle comparisons here: https://www.hwcooling.net/en/intel-core-i3-14100f-four-cores-whipped-to-the-max-review/36/

Just a word of warning: most reviewers don't really care about power consumption and they're even more indifferent to idle power, which means they rarely specify important information like motherboard and memory changes (including BIOS updates) and with an -F CPU since it doesn't have integrated graphics: the graphics card and driver version.
To be more explicit: I am very suspicious of idle numbers that show CPUs with the same die (12100, 13100 and 14100 have the same die and the same amount of cache) that show significant differences in idle power, since with Intel CPUs the variance is usually a few watts at most.
Soldato
It does look somewhat suspicious.
I am somewhat surprised there isn't much of a comparison at idle given the rise in NAS/personal servers these days.
Yeah, the best source I've found is when a thread like the one I linked does a spreadsheet comparing the numbers that their users report. I've never found the reviews particularly helpful because they're very hard to compare when they don't keep the same test system. I think there is almost certainly a significant difference between H0 and C0 CPUs, but other than that, it is hard to say anything reliably. I've even seen some claims that CPUs with E-Cores idle lower than CPUs without them, but I've never seen any evidence of that.
Idol CPU power use is largely irrelevant in this market. Its over all system power at the wall that matters and that’s largely down to everything else including software.
Soldato
I saw a spreadsheet on that forum but looked a but outdated unfortunately, but looking through the thread I do see mention of the 12100 and its idle consumption.
Need ChatGPT to trawl the web and create a google sheet pulling it all together (multiple forums).
Soldato
What if its running 24/7 tho. I think its pretty important tbh, however my case might be particular since I am building a fanless server so lower TDP and idle consumption are important.
Caporegime
If CPU A is pulling 300 watts under load with CPU B pulling 150 watts what what does it matter if CPU A pulls 5 Watts less at idle?
I mean.... do you use your computer or do you like to stare at it all day every day?

The CPU is going to change the profile, but other parts are much more important.
I’ve been building min max systems recently (just because I can and out of interest) and my lord are they complicated builds and efficiency (especially the last 10%) is stupidly expensive.
Soldato
Its for an UNRAID server/homelab so will be running docker containers - Plex, OpenVPN, Sonarr, Radarr, Nextcloud etc. This isn't my main rig.
Also I will be using a Streacom fanless case so efficiency key - silence is golden!
I guess I haven't got to the rest yet, as long as I meet the threshold for the PSU then I'm happy. Given the CPU has an iGPU it is going to help a lot.

The motherboard and PSU are usually more important than the CPU to the overall power use @ idle (assuming the same gen/socket of CPU) and if the power consumption is very low, they're much more important.

The PSU is critical and lower the system power draw the more complex the more difficult the calculations become. I’ve been through 9 PSU’s.
I’d also test at the power at least at the wall socket pre PDU surge device.
