When they have a recommended OS with their brand name on it (Raspbian/Raspberry Pi OS), it's a platform feature. Either I'd expect the hardware to provide some minimal battery or something for safe shutdown, or I'd expect the software to handle sudden power-loss gracefully. They provide both the hardware and the software, there's no way for blame to leave their ecosystem. Raspberry Pi can't redirect blame for filesys…

I applaud your user-first attitude to responsible branding, but we all know open source software and economics of mass production cheap boards don't work that way.

But that mini PC likely has as much as 10x the power draw... They are not interterchangable for lower power use cases

No they don't. I have a Dell Optiplex 3070 SFF (not even ultra small form factor, it is standard desktop sized) that idles at 8W. It has an i5-9500, 8GB memory, and a 128GB NVMe.

My Rpi Zero idles at 0.2W - it's nor in the same computing class as SFF/NUCs. I don't run a homelab in it; and I find it ideal for ambient, always on compute/networking/monitoring tasks

Am I crazy, or are we jumping from 4 to 5 whilst ignoring the fact that most of us still can't get hold of 4 due to the supply chain issues?

Those RPi4 supply problems seem to be mostly fixed. And RPi5 may come from different production line(s) such that it's available in quantity even if the 4s were not.

To be fair, you also need to account for consumption when you make the machine do something. The TDPs for these machines are in the 25-35W range, and hitting 50W does not seem unreasonable. You of course won't be running that the entire time. The larger SFF machines with 65W TDPs will go way above that. An orange pi 5 uses 7.5W under full load, 3.3W idle in comparison.

Is orange pi 5 as fast as 35W TDP intel CPU ? How many times slower it is than the 65W one ? Average consumption matters, not peak. And you can pin CPU to not go on higher frequencies if you don't want to go into inefficient max frequency/max voltage region. You will also be recycling already produced device.

According to Geekbench, an i5-8500T scores ~1100 single core, ~4000 multicore with it's 35W TDP, while the Orange Pi 5 gets ~840 single core and ~2900 multicore. About 75% of the performance at less than 20% of the power. Not too shabby, despite the orange pi being no efficiency star.

Recycling is good, but only to a point. At some point the cost of operation (and resource pressure from its use) will exceed the cost of a more efficient device - at least until we get abundant green power...

If the SFF is doing work, it might be done in a fraction of the time of the pi. Race to finish. Hard to say without real workloads, but if there are any plans of routinely pegging the CPU, most power efficient strategy is to buy a modern chip.

The orange pi 5 Geekbench score is ~75% of the i5-8500T used as example, so no - the sff won't be done in a fraction of the time. These CPUs are old and crusty after all...

I do agree that modern CPUs are required for high-load situations.

there hasn't been a shortage for a while now, but you probably didn't hear about it because shortages ending isn't considered newsworthy. it's the same with sriracha, you can pretty easily find it for msrp now, but lots of people still think it is hard to find because the last thing they heard on the topic was a news article about bottles selling on the gray market for $40-$80 back in may.

I check every so often, and checked before I posted that too. First hits I got from the Raspberry Pi website were all sold out, so I presumed it was business as usual. Cycling through a few more shops, I see it is available in some places now.

rpilocator.com is a good resource. right now the entire front page is all green, and you don't start seeing retailers with no stock until page 3.

Oh no they are shit. And I used to design embedded systems years ago. I know exactly what I'm talking about. And you basically outlined it: they are bad quality and we have all these power problems and here's the insane list of workarounds . Incidentally I ran mine of an Agilent E3614A which was worth 30x the price of the Pi.

they aren't industrial embedded computers, so comparing them to some $1500 hardened industrial embedded platform is not only unfair, it's not a comparison that's respectful of the other participants in the conversation. you're relying on people not knowing about embedded hardware so that it appears your comparison is fair. The Raspberry Pi is not an embedded platform in the ways that you are using for comparison. The…

> some $1500 hardened industrial embedded platform

It's just a (respectable( power supply. I'm assuming OP just wanted to say that power quality was not the issue.

Thanks! It wasn't on the awsome rust embedded github yet, but when I dig in I found it. The bl602 does support wifi, but only 2.4 and I presume at lower rates. It definitely doesn't run linux though. But I wouldn't put it past someone to figure out a way.

> t definitely doesn't run linux though.

Sorry I was thinking of the 0x64, although it's entirely possible to get some form of Linux running.

I've also compared many 1L PCs from a performance/price/power consumption perspective. I decided on the HP prodesk/ elitedesk 400/800 G5 with the i5-9500T. It idles at ~2-3W and has considerably more computing and storage than these embedded solutions. I only see something like a raspberry pi be handy when relying on GPIO ports.

I don't know what you did to get yours idling that low. My 800 i5-9500t idles at 9w. I took out the flex io module & wifi card, and make sure nvme has "spin down" but still nowhere near that low. I had some Acer chromeboxes that would do 4.5w easy without any tuning or setup, and they used pretty low end dyal-core i3's from just barely before the i5-9500t. Generally I don't think servethehome finds many tiny mini-pcs…

I can attest to coffeeri's consumption, albeit on pure server use-case only. I own a OptiPlex 3080 with an i5-10500T and under default BIOS settings (power states and whatnot), I was very surprised to see a 1.7-2.5w power draw on idle, but under typical desktop use, this becomes 6-8w. If this is your draw under a server deployment as well, unfortunately I don't know of any methods to rectify this personally.

When it has to roar however, the draw is substantial compared to my ODroid, but since it idles the majority of the time, I'll take it.

Sounds like this would be very annoying compared to a SBC. You have typically several SPI, UART, I2C, gpio interfaces on the pin header on usual ARM SBCs. Ready to use from Linux via standard API, using DMA, etc.

I once had a very simple I2C operation performed on an Orange Pi running project nerves. I had to add a try-again loop to the I2C operation, because the underlying OS kept disrupting the I2C timing. I2C is generally run between 100-400 KHz, so you'd think it wouldn't be an issue, but it definitely was. You can get around this by patching the kernel to carve out timing protection for those operations, but speaking as…

100 khz is still very fast, with sub-millisecond I2C tranfers possible.

You'll have the same issue on any SBC running Linux. You'd need to carefully use realtime process scheduling, if you want more predictable timing on a general purpose OS for such stringent timing requirements.
