SBC / Low Power boards general - Raspberry Pi and what not

  • 🐕 I am attempting to get the site runnning as fast as possible. If you are experiencing slow page load times, please report it.
Yeah while the Pi foundation is sitting on their laurels barely wanting to modernize their SBCs, Khadas is making credit card sized ARM equivalent to NUCs lol.

How much better wifi-range-wise is the 2nd edition of the Pi0? Can't find one for love nor money without buying it bundled with shit i don't need and wondering if i should just give up for a few months.
 
Christ, seeing as Rpi's had supply issues, and is now selling for well over 100, that Khadra Edge looks rediculous for being firmly in its price bracket for the basic version

RISC-V is probably the future for Privacy conscious folks. But it'll take a while to get where ARM is at.

I'm replying to this waaay to late but recently I saw Visionfive 2's being available for preorder on amazon and honestly while they may not be at arm level (Particularly Apple Arm level) the 8GB model has, at the very least reached "old ibm thinkpad" level.
Which is honestly all I need, just a computer without a built-in backdoor, no known vulnerabilities (eg spectre and meltdown, which the thinkpads are vulnerable to), is rather cheap and can do some basic computing on. It's a shame that this came out while broke though.

The situation with SBC availability is ridiculous. I needed some very low powered computers to run headless and I just opted to get some shitty old thin clients. They're good enough to run OpenBSD, manage SDR, and control an antenna, so whatever. They aren't what I wanted, but at 20$ a pop I couldn't get an SBC for double that anywhere I looked.

Gotta love our just-in-time (until lead times are measured in years), late-stage corporatism bullshit supply chain...the resilency of paper mache soaked in gasoline and the backup planning of Dilbert's boss..

Thought not a SBC, the Raspberry Pi Pico microcontrollers are pretty cool pieces of kit. I'd even say it's a bit more useful and practical than a full Pi if you want to deploy it in some set and forget state where hard power offs are the norm. Still figuring out the C libraries for some cheap sensors but so far it's nice.

It should improve soon. I hope. Other parts of the tech sector are saying they have a glut of product to move. You can't really get a good SBC for $20. The Odroid C4 is pretty good but after getting storage and a case, it comes to like $80-100.

I got my rock 5b the other day. I pre-ordered it so I got it without warning.

I don't think its ready for prime time. I've had issues with it. Mainly the software side of things. Android works nice, but I get no sound. Used Armbian to install Gnome but Retroarch has no arm64 cores for linux desktop. No vulkan support in desktop either. Used Radxa's build of Debian and got stuck on boot after I updated it and rebooted it. I put the community build of debian sid on there atm. Wanna try out how it handles cpu x264 encoding.

At least with Odroid, they're images usually work without issue when the hardware is released. I hope the rk3588 has a great future a head of it.

edit: I tested cpu encoding. With an SD file, rk3588 does it with 70fps per second while the s922x does it at 35fps per second.

SNAFU. ARM boards take years to work properly, if they ever do at all. RPi 4's GPU driver effort is like a dumpster dive for more performance, and they're the biggest name in SBCs. Return to monke x86.

It looks like the RK3588 is similar to Intel's 4-core Pentium Silver N6005 (Jasper Lake) in both single and multi-threaded performance. Which is now in the ODROID-H3+. So 4-8 Gracemont cores will put it to shame soon. I think AMD's Mendocino could be similar to that with 2-4 of its bigger Zen 2 cores, but it remains to be seen if it will reach low price points and SBCs. Mendocino is in some cheaper AYA NEO handhelds and the dual-core Athlons could be cheap.

I recently had an adventure I very much detailed in the GPU thread with an older convertible for around 150 bucks. My conclusion - just get something x86 used. It'll be cheaper, it'll be often faster, it'll work better and it'll be more compatible and more easily expandable. And depending on what you get and you're open to experimentation you can run x86 android on it too. If you pick carefully you'll even have something that's in roughly the same power consumption bracket as some of the high end ARMs while actually coming with cooling that's up to it. (instead of having to buy that one extra too) These ARM boards are just a bad choice besides some niche uses where you really need a very low-powered one but a microcontroller isn't quite cutting it, but these are never these "desktop" SBCs. Just bad value for the money.

Helpful hint for everyone planning on spending two weeks building a custom enclosure for your Raspberry Pi: please buy extension cables for routing power and HDMI to the back before you design, assemble, sand, putty, sand, prime, sand, spraypaint and lacquer the thing.

I've gone through three right-angle USB-C PD cables that just don't fit with a Hail Mary 4th on the way.

I was on the odroid forums and someone from the company said they put out the H3 series to compete with these new 3588 chips.

An aside, I did that SD video encode at the slow preset and with the animation tune. I just did another encode to x264 from a 1080p VP9. 2pass. First pass was slow while the second did it in around 20 minutes. No tuning or preset options selected.
 
I bet the pi 5 reveal will just get bombarded with this screeching. How grand. :semperfidelis:
