Not on the linked page. "Will my Raspberry Pi 4 power supply work with Raspberry Pi 5? "Raspberry Pi 5 is a higher-performance computer than Raspberry Pi 4, and you may have problems using an under-powered supply. We recommend a high-quality 5W 5A USB-C power supply, such as the new Raspberry Pi 27W USB-C Power Supply." The question asks about power requirements, but the answer is about performance? The first time I…

> we recommend a 5w PSU like our new 27W PSU Ermmm, what?

It's clearly a typo, and should be 5V.

But then you get 5V 5A ... 27W that is clearly incorrect too. So my guess is nobody is proofreading the technical specifications, and everybody that cares was kept away from that page.

You can netboot a Pi. Every Pi in my house netboots. I have a whole bunch of them. Some play games, some play videos, some play music, and a few other minor things. Because they all netboot, you can change what each one does by renaming a file on the server and then rebooting it. It's great.

You made me curious: what do use them for exactly?

One is the "smart" part of my smart TV. One powers my hifi. One connects my non-networked printer to the network.

One is an NTP server which gets the time from GPS, although that one will probably be retired soon, internet time works fine.

I used to have one inside a MAME cabinet but I upgraded it to a "real" PC because the Pi isn't really powerful enough for modern versions of MAME.

Out of curiosity, does 5V/5A USB-C changer common? All of my USB-C Chargers has 5V/3A only.

They're not, and it's a very annoying requirement. Even 5V/3A was hard to provide reliably. On the other hand, rock pi supports 12V/2A, which modern chargers will provide without any issue.

Anything that can't supply 5V/3A is not a modern charger, that combination is mandated by USB-PD for anything that can provide 15W.

I'd like to see an RPi that includes an Arduino (or maybe an ESP32) on board, with some way to easily connect things to that Arduino's GPIO pins, and with the Arduino programmable and controllable from the RPi. This would let you run things that need real time GPIO access and real time interrupt handlings on the Arduino, and would also give you DAC and ADC.

The RP1 has two Cortex M3 cores and a PIO core, and is responsible for the GPIO pins. So I think it already has something close to what you want.

I can't find anything about the RP1 online, do you have a source?

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…

> "normal" USB-C power

I have no idea what kind of USB-C PSU one can call "normal", but allowing higher voltages would be really good.

Your answer is more direct and uses fewer words. Can you help them fix their product page?

Should we get Intel and AMD to clarify their product pages at the same time?

Haha - and while we’re at it, might as well start putting labels on Apple’s performance graph slides :-)

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.

Genuinely curious: why does their announcement upset you so much? Most of the tech world announces products, executes a marketing strategy and then releases stock into the market. You make it sound like someone left you standing at the altar. You didn't know it existed an hour ago. If you were on a long vacation, it might have released before your return. Why get angry?

Scalpers want to know if it's worth it to order en masse so they need more specs to feel the market ? shrugs

median is a type of average. the parent commenter means the mean

Is this correct? I know no definition where median can be interpreted as an average.

Threadrippers use 50W+ at idle, so no, it won't just "throttle down"

Mine uses about 80, but yeah, you can get rid of 80W passively. Consider a 100 watt incandescent light bulb; no fan!

And how hot does the bulb get? Googling yields "The surface temperature of incandescent light bulbs varies from 150 to more than 250 degrees" (https://www.pacificlamp.com/temperature-of-a-100-watt-bulb.a...). Which, googling says, is likely hot enough to damage a CPU.

I've had this idea for a while now but what if someone built a game console based on the Pi hardware? I know lots of people use their pi's for retro gaming but I'd really like to see some new games made for the hardware. Does anyone know if there's a group working on this or would be interested in creating one?

You can run PICO-8 on a Raspberry Pi today. Still a "retro" feel, but they are all new games being written for the platform. https://www.lexaloffle.com/bbs/?tid=3085
