one big advantage pi had over minipc is a lot of the minipcs are in the 30 watt range while the early pis were single digit watts. that advantage has decayed over time though...

A good number of the mini PC's idle under 12W. My i5-6500t does. Yeah they ramp up under load to 30W, but a before rpi5 to start to ramp up like that would've been way more compute than an RPi could offer.

Also notably there are some low power options too. My first kube cluster was on these nice 2014 Acer Chromebox cxi's; they idled at 6w! Crazy slow 2957u Celeron processor, but I used it a node as my desktop for ~2 years (with 16GB ram). But it had gobs of USB bandwidth, mpcie wifi, sata, gigabit, and if i'd sprung for i3 models it probably would have been downright pleasant to use versus the 1.6GHz no turbo dual core I was getting.

Personally I've avoided the atom cores generally, but there's been a variety of decent low power offerings of big cores for a while. Heck, my Ultrabook tablet is ~6W when running, with screen on, with a i5-7200u. 15W TDP core with some additional TDP up available.

Point is, there's been a range of pretty low power x86 offerings. Just, not always super obvious.

the n100 mini pc i got here runs at around 3.5 watts while running homeassistant with a unifi network server while having around two dozen devices connected. under debian 12 minimal.

How are you measuring that? I've been scouring the web for low-idle-power builds and 3.5 watts is far below the best builds I've found (assuming that 3.5 watts is measured at-the-wall).

The futro S740, popular with selfhosters in Germany, gets similar wattage for people [0]. On a slightly older CPU (J4105).

I can't measure values below 10W myself, but with 2 SSDs and 8GB RAM it never goes above that value, even under full load.

I've measured about 5w from the wall with Pentium J5005 based Dell thin client which has a tiny fan, one SSD, two RAM modules. No idea how N100 compares to J5005.
Re:Intel N100 Radxa X4 First Thoughts by geerlingguy on Sunday July 28, 2024 @04:13PM (#41095640)
N100 runs slightly hotter, I've seen it more like 6-8W

Just a cheap measurement adapter you plug between the wall and cable.

The nice thing about n100 Is its ability to disable the iGPU in the bios, saving you a little bit of power. But you have to reset the bios on the board to regain any output if you might need it later.

Sounds interesting, could you please share brand and model? Also, do you know how many SSDs/HDDs you can put inside? Could be a good replacement to have a low power NAS.
Re:Intel N100 Radxa X4 First Thoughts by jauntywundrkind on Monday July 29, 2024 @05:19PM (#41103912)
Unless I'm running on battery, that's a pretty abstract win to me in the US. My i5-6500t's 10W for all 8760 hours of the year is 87kWh; less would be nice but my power bill is already under $10/year at that rate.

It is great that something on par is so affordable & even lower power though! And what I bought was a value because it was used, where-as now you can buy new. It's felt like the atom lineup was kind of slow rolling things & there hasnt been much availability for cheap AMD systems. These low price low power e-cores systems have really changed the game, have expanded the value proposition a lot versus the used-x86 mini PC or io limited ARM market's long stalemate.

Apple claims that the latest Mac minis draw 7 W at idle:

E.g., Apple M2 Pro chip, 32GB unified memory, 8TB SSD.

Re:Intel N100 Radxa X4 First Thoughts by geerlingguy on Sunday July 28, 2024 @04:12PM (#41095633)
Apple's still the only company that matches other Arm boards/servers on efficiency (perf/W) + idle power draw. AMD has been doing a little better, Intel slightly more so.

I am keeping an eye out for a cheap M1 Mac Mini on my local Craigslist because once you yank it out of its huge metal case, which is like half PSU, the board itself is quite small. Apparently, the PSU only outputs 12W across the entire power connector, so easily powered by a barrel jack. I quite like the idea of playing around with macOS as a SBC OS, but even just designing a smaller case with sufficient cooling would be fun too.

> Apparently, the PSU only outputs 12W across the entire power connector

What is your source? Because, according to the link shared by op, they can consume up to 50W or 100W depending on the model.

Re:Intel N100 Radxa X4 First Thoughts by wpm on Wednesday July 31, 2024 @05:52PM (#41123871)
Whoops, meant 12V not 12W. Meaning it can be powered off of a big enough battery bank or a simple barrel plug power brick.
Re:Intel N100 Radxa X4 First Thoughts by GTP on Monday July 29, 2024 @11:02AM (#41101009)
Interesting, but they can jump up to 50W or 100W depending on the model. Which such a big swing, you really need to consider your specific use case to see what will be the actual power consumption.
Re:Intel N100 Radxa X4 First Thoughts by paulmd on Sunday July 28, 2024 @03:55PM (#41095528)
no, the booksize pcs of the time were pretty comparable to what you see today in terms of power. rpi was a bit cheaper and lower-power... but also vastly slower. Like a factor of 4x if not more.

Remember: single-core, ARMv6Z 32b, 700 mhz in-order, using USB 2.0 as a system bus and booting over that same shared 500mbps-unidirectional system bus, with 256mb memory. Versus dual-core x86 64b 1580 MHz out-of-order with a proper SOC design, and also having dedicated USB 3.0 for peripheral connectivity, with 2GB memory.

For say $80-100 loaded on a rpi vs $100-125 on a Liva/Liva X it was a no-brainer even at the time, and the liva still sipped power (because it was using e-cores). The 1B+ model improved things a little (512mb) but still, not a good showing for a product that competed directly with these x86 nettop machines.

And in the grand scheme of things... 1w idle/5w load vs 3w idle/12W load is not anything you're ever going to notice, especially given the massive increase in performance it afforded.

RPi also released at $35 for Model B, two years earlier.
Re:Intel N100 Radxa X4 First Thoughts by paulmd on Monday July 29, 2024 @12:32PM (#41101669)
Yes, that's always been the marketing gimmick. $35, for something with no case, no storage, no power adapter (and off-the-shelf adapters were not suitable at the time), that had a critical flaw with its system bus/all USB devices for the first 2 years of its existence. That bug didn't get fixed until feb 2014, which is basically the same time the liva launched.

also, booksizes/nettops didn't materialize into existence in 2014 either. and you have to remember that the raspberry pi 2 didn't launch until 2015, so actually they were direct contemporaries for at least a year.

so if you wanted to run the early-adopter softfp distro on a $35[0] SBC in 2012 then sure, I agree, go for it. But there were turnkey solutions in the x86 space that weren't that much more expensive.

[0] $35 + $20 case + $15 adapter + $20 SD card + $20 SD card + $10 SD card + ....

Re:Intel N100 Radxa X4 First Thoughts by p_l on Monday July 29, 2024 @12:52PM (#41101804)
ECS Liva according to reviews from 2014 would cost me about $170~180. Would still require keyboard/mouse and something to display with.

Sure, it would have a case and WiFi in that price.

It would also miss GPIO header, which was major selling point of initial Raspberry Pi efforts (before it became so popular for other uses, when it was still targeting education).

A lot of then-common phone chargers worked. A random SD card wasn't that much of an issue. A kit with charger, NOOBS SDcard, and random assortment of extra bits to play with the electronics regularly could be acquired for ~100 USD if not less.

If I wanted to play with small-size BayTrail x86, Liva was fine choice. If I needed a small general purpose computer, too.

Not a very good choice if I wanted to graduate from Arduino towards somewhat more capable setup without requiring either expensive I/O boards or hacking an IO board out of Arduino or another MCU.

https://i.imgur.com/dnJACSd.png (these had a $25 rebate)

these were $115 barebones iirc (add SSD and memory). https://www.servethehome.com/zotac-zbox-bi320-u-w2-review-so...

$180 loaded for the whole thing (and this is indicative of what I paid for ssd+memory at the time, etc) https://i.imgur.com/9nmBQ0V.png https://i.imgur.com/I98CS6i.png

like idk what to say dude but MSRP reviews aren't always reflective of street prices back then, things used to go back on clearance sales before moore's law died.

yes, you absolutely could get x86 stuff that was price-competitive with the rpi once you loaded it up. the $35 price is, as I have stated, a red herring considering all the stuff that nobody had on-hand in 2012 like proper usb chargers that could run a rpi stable, plus the massive kernel problems involved for the first few years.

It's $100 loaded cost for a raspberry pi 1b or 1b+ that doesn't even work, because of kernel bugs I already linked, or just buy x86 for $75-180 and get something an order of magnitude faster that actually works and runs standard x86 distros and drivers. Stop comparing 1/3 of a pc to a out-of-the-box pc as if the price means anything at that point, this is getting to be bad-faith.

Especially when the product didn’t fucking work.

Like it’s the same damn story as ROCm, right? People want serious financial consideration as if they have delivered a working product, minus the delivering the working product. Come back in 5 years when your product works.

I will sell you a brick with a piece of paper that says “10,000 tflops” taped to it. The perf/$ will be out of this world, but there will be some “usability issues”. PM me for details.
