I'm tired of information being vague, under-specified, or only available under NDA (if you're lucky). I'm not stupid enough to hop on this ride again. Are there any fully open (in terms of schematics, firmware) RISCV rpi-"compatibles" out there? I'd be happy to pay triple the price of this thing for a power-efficient linux-capable sbc that is open.

Any board based on StarFive's JH7110 is currently best in this regard, I think. Datasheet & reference manual for this SoC is available.

Especially their VisionFive 2 board. I've even downloaded a schematic for it (although older revision than actual board I have). And they're pretty good about upstreaming drivers.

That said: what you probably care about is documentation for integrated peripherals (esp. GPU), and existence of open source, mature drivers for those.

RPi is very good in this regard. Afaik the only binary blobs there is some GPU/SoC firmware, and (maybe) some boot code.

RPi's in general are very well supported & documented, and its software ecosystem is very mature compared to anything RISC-V based.

Could you pinpoint what you think is lacking there?

Other ARM based boards may offer more bang/$. Likely at the cost of documentation or driver support (Beagleboard being an exception).

You can check some Beelinks or some other Chinese brands over Amazon. Note that I haven't used any of them tho I'm considering getting one.

Main home server/NAS is a Ryzen 7 Beelink with 64GB. Works a treat. Fan is audible when you're hammering the CPU (doing a large backup, unpacking downloaded media, running a Minecraft server with multiple users) but other than that it's not audible from ~5ft away.

This, I've been pretty happy with it as well, it's so much easier to set up as a kubernetes node than a RPi.

At this point, Alder Lakes like N100 processors and multiple sff computers have dominated the market while RPI struggled with the supply chain. now there are multiple clones as well. I’m not sure if The Pi5 will ever reach former glory days.

That's true as long as you don't mind using modified vendor supplied operating systems. Most of these advanced boards will lock you into some patched Ubuntu version. So far from the ones I've worked only the Pi and a patched Rockpro64 allows you to boot some generic USB installer from UEFI and have the system your way with mainline kernel support.

I didn't see any mention of UEFI in my first read through about the Pi 5. Did I just miss it? I would like to have a quiet and reasonably performant ARM aarch64 box at this price point, but only if it supports UEFI without needing to resort to silly EFI system partition tricks (which the Pi 4 required, last I knew).

No official UEFI support at this time.

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…

I think it's completely acceptable so long that a legacy compatible "Pi SE" options would be available, in Pi 3 and Pi 4 form factors. Raspberry Pi are used installed as components into third party engineered products, and Raspberry Pi brand holds no value to potential industrial customers if new products did not technologically exchange with existing such products. That is to say the exact mounting details, electric…

Check out the “obsolescence statement” on the Raspberry Pi product pages. The 3B+ will remain in production until at least 2028 https://www.raspberrypi.com/products/raspberry-pi-3-model-b-... and the 4 until at least 2031 https://www.raspberrypi.com/products/raspberry-pi-4-model-b/...

But it says that active cooling is only necessary for heavy workload, if you're fine with that then no fan required.

sure, but why pay money for functionality you're just gonna turn off (components, higher clock speed)

Phoronix tested the Pi 5 with and without the official heatsink, and without it peaked at around 90C (same temp my Intel Mac Mini from 2018 likes to hover around) and never throttled during benchmarks. You don't need to downclock, undervolt, or turn anything off to run fanless.

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?

The Raspberry Pi 5 will only be for sale to individuals until the end of this year (no industrial customers competing for inventory like the older models)

> I guess that is fair, especially with inflation nowadays. The accumulated inflation in the US since June 2019 is c. 17%.[1] This means US$ 55 in June 2019 is "worth" c. US$ 64.35 today. So it seems that you get a 4GB Raspi 5 for c. 7.25% less today. The "US Real Average Hourly Earnings" have increase by ca. 22% in the same period, from US$ 27.75 to US$ 33.82.[2] So an average person needs to work c. 12% less to buy…

Please stop using “average” for wage comparisons. It’s an utterly useless metric for showing if wages are moving or not. If you must use average, then you should remove the top 5% from the average.

> If you must use average, then you should remove the top 5% from the average.

5% is too arbitrary, just use the median.
