Rasbperry Pis are losing their competitive edge for non-embedded applications to sub $150 mini PCs, which support Linux/Windows and will come with enclosure, NVMe slot, power button etc. The mini PCs are also generally much faster.

Where can I find these mini PCs? I am trying to find hardware for an upcoming project and I’m considering the Pi but would love to see some alternatives.

I just stalk eBay's Buy It Now. Got an i7-7700T w/32GB RAM and a 256GB NVMe for $163 shipped+tax. Previously got an i7-6700T with 1 stick of 16GB RAM so it was cheaper to match that for 32GB total.

If you can get friendly with local electronics recyclers or auction buyers you might do way better.

Hmm. I'm disappointed honestly, I was looking forward to USB-C with display port and "normal" USB-C power. Is there any reasonable option with software support that comes even close to what RPI offers? I don't want an SBC where I have to use some strange back ported, super old, kernel with little to no chance of getting updates. Maybe I should just go for an X86 board? Lattepanda Delta, or Khadas Mind whenever that's…

You could also get a framework laptop mainboard with a case: https://frame.work/products/cooler-master-mainboard-case

Isn't the link you posted, only for the case?

A NVMe compatible M.2 M Key connector (like the Rock 5 Model B [0] has) would have been really nice. I'm starting to accumulate old but good, yet small in storage space terms NVMe's which I'm no longer needing, but which would be perfect for a Raspi. Even if the PCIe bus were an older generation and not as performant as the NVMe. The microSD card slot is really great to have, to get up-and-running, but once it's clea…

The blog post says they're releasing a M.2 hat in "early 2024"

I don't love that you'll have to choose between PoE, M.2, or active cooling / a case.

imho pi's market segment is clearly nerding, tinkering and low-power gpio-adapter. using them as media-pc, router or even desktop is an exercise.

I don’t think that’s the only reason to use one. They also have value as a well known and well supported hardware target even in cases where the GPIOs aren’t needed. For example, the hobby 3D printer community uses them extensively for things like Octoprint where the GPIOs aren’t needed - but the Pi continues to be much more popular than other options because it’s very well supported. A user doesn’t need to figure ou…

true, there are cases, but "well known" and "well supported" is the point i tried to make in favor of enterprise thin-clients and the like as they are pc's and run most commodity operating systems and applications.

> hobby 3D printer community uses them extensively

i'm sure they are (literally)

Yeah my intel atom NUCs run at 5W idle and 10W load and they're a ton faster than a pi 4. Probably a pi 5 too. It's not very impressive. And that's with a real SSD.

Yeah, the intel n100 is absolutely fantastic. but even at bargain basement price its at least 2-4x the price: https://www.amazon.co.uk/TRIGKEY-Mini-PC-Desktop-Computer/dp... I have the above, it's max powerdraw is From what I've seen the pi5 is 1/3rd faster than the intel j5005. (in pybench at least.) but comparing to a real intel NUC, of course its going to be faster, the NUC costs an entire order of magnitude more.

I bought an N100 for 160 USD including an SSD off of AliExpress. Thats 2x the cost of an rpi4. I benchmarked it and cpu perf is roughly 2x the rpi however i/o was easily 10x without any sdcard or USB shenanigans. Bonus because it's an Intel chip I can use the regular x86-64 os builds instead of some goofy fork. That's very compelling if you don't need a gpio or any of the raspberry pi accessories for your use case.

The NUC's GPIO header: crickets

There was at least one NUC with a full GPIO header set. The DE3815TYKHE. I've done motor control, I2C and sensor IO with it and it was rock solid on that little NUC. There was also the UP Board which was an Atom SOC with PI compatible GPIO. I believe that's still in production?!

Oh wow that's the first I'm seeing that, looks like it's still available though a bit pricey for over 1 GB of memory.

Then again that is severely dated, the Atom was a very capable processor... when it launched, almost a decade ago.

Fwiw I bought a sleeve for my M.2 SSD and it plugs into usb3 with very little slowdown. It gets 500MiB read and 1.2GiB write. Haven’t measured vs native M.2 to compare, but it’s fast enough that I’d be surprised if the pi were blocked waiting for I/O vs native M.2. And native M.2 comes with increased manufacturing complexity.

Are you sure it's 1.2GiB? The RPi comes with 5Gb/s USB ports, which is 596MiB/s Now that I think about it, Linux may be caching writes, but even then double the write speed compared to the read speed seems weird.

Oh, I didn’t test on a pi, just a mac. And yeah the double write speed was super weird. Thanks for answering my internal question about why ~500MiB seemed to be the max.

I’ve purchased a few HP Elitedesk 800 G3 Minis (refurbished) for about $125 on Amazon. They even come with Windows 10 if you’re looking for that. They’re a deal considering the Pi’s extra expenses like power, case, storage, etc.

I did something similar too, just beware of refurbishers putting cheap/trash SSD disks in those machine, they can stop working all of a sudden sooner than later (I experienced that on my skin)
