I have a Raspberry Pi 4 Model B with 8GB of RAM, and I’m looking for a bit more powerful solution that would have similar power consumption. I would like to host a Minecraft server, but chunks take too long to generate. Do you have any recommendations?
To give a different opinion than all the thin-clients, old laptops can be a good choice too. I am a bit preferrential to really nice old thinkpads.
If you buy them used you can get insane prices (~$40) and also you get all the laptop conveniences of a keyboard, screen, battery (for power failure). Also I think the power/performance ratio is pretty much the same to the thin clients.
Using the laptops battery isn’t a good long term solution though as having it plugged in all the time will wear it down fast, not to mention that the battery is build for maximum energy density and not durability/safety. It just simply not working when it is finally needed is almost a pretty light issue when it can just also inflate and pose a huge fire risk next to all of your data. Laptops are great power efficient platforms though for servers
First off, I think you’re completely right in that laptop batteries are definitely a non-ideal solution. And, I’m really not an expert in this, so take my words with a grain of salt.
You could mitigate a bit of the dangers by doing some of the following (I only did the first):
- Reducing the max charge level to 50% of the capacity.
- Monitor your batteries health to alert for any discrepancies.
- Switch out your batteries every couple of years (which is super easy without downtime on the aformentioned old thinkpads).
If you are an under $100 budget, there seems to be an argument that maybe you are willing to risk a little bit for that extra power reliability.
For that the laptop has to support a charge level on a hardware level though, just setting a limit will cause it to constantly switch between using the battery and charging the battery which would be much worse than keeping it at 100%. Most older and budget systems don’t support that
Look for second hand business PCs. They can be had extremely cheap and draw almost no power.
I have a Futro S920 and an HP ProDesk mini G300 (or something like that, never understood the naming). Both draw about 5-7W from the wall, which is roughly the same as my RPi3b.
The HP one has an i5 6500T and 16GB RAM, both upgradeable. There’s also a real 2.5" slot including SATA connector on the board, an M.2 slot and an NGFF slot. Really cool device. The only slightly annoying thing is, that the fan can’t be controlled (or at least Debian can’t detect any PWM devices), and it’s always slightly-on, which can be annoying. But for 100€? I think that’s a good deal.
Yeah, thin clients are the way to go, but tgey will draw more than 5-7 Watt under load.
Sure, but is that really so much more (for a given amount of compute) than an RPi?
My Futro S740 with an J4105 CPU consumes up to 14 Watts according to this article. It is faster than a rpi 4b plus i bought it refurbished for 40€. I think a system with an I5 6500t will need even more power under load.
How would an i5 6500T compare to a mini pc with an N100 or N305 like the beelink?
I’m serious debating if I should get a beelink (or equivalent) with an N100 and 16GB ram or go for an Optiplex with an i5 6500T and 8GB ram. Both are about the same price where I am located.
Im mainly interested in power usage and performance and not so much in upgradability.
I have a zx01 or something like that from AliExpress with an N100 and 16GB. Those little machines are seriously impressive. It’s running Garuda and my son has not complained once about any game he’s tried to play. I don’t play games, I just bought it on a whim cause it’s tiny and $150 or so. I’ve run several systems on it without a hitch. I’m pretty certain it’ll hose a Minecraft server without an issue.
Lenovo ThinkCentre Tiny, or another brand similar.
The pricing since the pandemic has been cheaper than Raspberry Pi4’s in my region.

OrangePi makes a decent solution with a built-in 8GB eMMC module. Makes it much faster. Dunno if you are CPU or IO bound on the RPi4.
