Is there any high end 5/7nm SBC? Phone chips don't seem to escape the phone market.

Orange Pi 5, "plus" version also has 2gen 1-lane pci-e (M.2 wifi), and 3gen 4-lane pci-e (M.2 SSD) and 2x2.5Gbit ethernet. 8nm, pretty power efficient. I've measured it to run at 0.7A@5V idle and 1.2A@5V with all 8 cores loaded with md5sum /dev/zero; iirc it had 1 ethernet connected, no other periphery. Running on Armbian.

I have the non-plus and have been pretty happy with it.

A lot more computing power than the Pi 4 and older home server it replaced. The M.2 slot was an absolute game changer. Real onboard storage is a must.

It runs a few low resource VMs in the garage and I almost completely forget it exists.

For me the advantage of Raspberry pi was passive cooling without worrying about any moving objects and running 24/7. Being affordable was another clear advantage. These two does not apply here anymore.

I might be wrong but buying a used mini pc like Nuc or SFF PCs seems to be more reasonable than buying a 80$ SBC + Case and adapter costs.

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’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.

There is also a general improvement in code support by sticking with x86. I bought a similar 10 year old i5 based workstation dell and so many little things just work _better_. I didn't realize just how much of my battles were based on hardware architecture issues.

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.

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.

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 out any CLI magic to get things to work, they can just grab a pre-made SD card image and go to town. And if they do have a problem, it’ll probably be the same problem that a few thousand other people have had, so solutions will be well documented.

I question whether it's wise to launch a new product before the supply chain issues which have plagued Raspberry Pi for years have been fully resolved. Granted, the situation has improved slightly over the past few months. But you will still find Pi 4s out of stock more often than not. The CEO said last year not to expect a Pi 5 in 2023, because they wanted to take the time to recover. Why the u-turn? https://www.the…

The point here is likely to pull the rug out from under scalpers' feet. With the Raspberry Pi 5 out in two weeks, all the held-back inventory of older models will be dumped, prices will plummet, availability will become a non-issue. In that sense it's a wise move.

Finding older models were also almost impossible in the past two years. It's unlikely that Raspberry Pi 5 will solve the issue. But even so, it's not a wise move because what is the point of bringing a new model when they can't make it available to normal people?

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…

This would limit you to just connect SSDs. Their solution opens up more versatile access to other PCIe devices.

It would not limit you to just SSDs, the m.2 connector on the rk3588 devices generally exposes 4 pcie lanes and an adapter to make this a full pcie slot is already available. So really an m.2 nvme connector is the best of both, you can turn it into any other pcie connector you want via an adapter, but you can just put an nvme ssd directly on the board without a hat.

I got a 2018 Intel NUC for 100 EUR and love it. It's so damn fast and small, I immediately bought another one in a fit of impulse.
