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 a typo: They mean 5A I think.

Alright so 27W with heavy peripheral draw then? But 12 W still means it'll be drawing 2.4 amps instead of 1.6 when a random process decides to 100% it. I guess we can always underclock it. The real unanswered question is, does it finally have a damn sleep mode so it can save power when idle.

Jeff Geerling measured 1.8W idle power draw. Based on my experience with previous Pis, I bet you’ll be able to drop that even further by turning off unused board components at boot time.

True, I've gotten Pi 4s pretty low (< 1W), disabling the LEDs, Ethernet, HDMI, and USB controller, but it's never gonna equal a proper suspend.

I may be completely off base here, but maybe the rpi wasn't the best tool for the project then? What was it, if I may ask?

I mean, I'd be curious what you'd have suggested! We needed it to be small, low power, low heat, provide hardware level access to a camera module, be ethernet accessible. Oh, and under $100 including a fixed M-mount lens. At the time, it didn't seem like rolling our own hardware would have been faster. I would argue - given we succeeded at sub 1ms syncronization - that the Pi was close to the perfect tool. It just wo…

You already solved your issue, but still I'll mention it:

For my Pi's I buy a separate RTC (uses GPIO pins). There's various available, the DS3231 is the most expensive but also the best. If you buy it in bulk (70+) I suppose you could shave some money off. If you're OK with a cheaper one (less than half the price) which functions less well (but still does the job) then PCF8523. I got mine from a local Adafruit reseller.

rpi4 was kind of slow for light desktop browsing in my experience, without overclocking.

I kind of wonder how the new PI would work in that scenario.

I used it with SSD drive, by USB.

At the moment the product page is just a list of specs, but the blog post goes into much more detail, including describing the new RP1 I/O controller: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/ On pre-ordering: > We’re also giving every print subscriber to The MagPi and HackSpace magazines a single-use code, giving them priority access to Raspberry Pi 5 hardware.

I think it’s notable that the chip powering the RP5 is built on a 16nm process. (The RP4 was on 26nm). This is a nearly 10 year old manufacturing process and it’s silly to compare the performance per watt to any Intel or Arm chip on the market today. On such an old node, it’s not surprising that the power draw is so high. Of course an M2 would smoke a RP5 at a much lower power. But the RP5 is 60 bucks!

Side note, lowering the process means smaller wires and more susceptibility to ESD. I've never vacuumed a Pi 4, but also haven't lost any to it in countless sketchy mounting points. That might change on the 5, GPUs built on 10 nm and lower just die if you touch them wrong.

Hi, I've been testing the RPi5 for a few weeks and have written up my results and benchmarks on Twitter. https://x.com/alexellisuk/status/1707296079849365650?s=20 This is so much quicker for clusters, servers and headless use, that I don't think I'd consider buying any more RPi4s myself.

Are those results available anywhere else?

Did you read the blog post? :) "One of the most exciting additions to the Raspberry Pi 5 feature set is the single-lane PCI Express 2.0 interface. Intended to support fast peripherals, it is exposed on a 16-pin, 0.5mm pitch FPC connector on the left-hand side of the board. From early 2024, we will be offering a pair of mechanical adapter boards which convert between this connector and a subset of the M.2 standard, al…

What is (or would be) the "Tsundoku" equivalent for Raspberry Pi? I started with Pi-Hole a few years back but ended up with a commercial paid DNS resolver. The timeline usually goes like this -- will stumble on another interesting video of Jeff Geerling, then spend the weekend tinkering with the Pi, keeps running, forget about it, found it to be not needed, plugs off and is lying around. [Tsundoku]( https://en.wikipe…

Because every machine you use requires maintenance whereas NextDNS [1] costs 2 EUR/month. The time wasted on maintenance alone is worth more, add to that the electricity bill.

Examples: I also use one with OpenWrt (though I'd prefer OPNsense on it), and I use one as PiKVM. I use one with a portable HackRF (3D printed case), batteries included. I use two with Pimoroni Enviro+, and I have a fun Turing Pi 2 homelab/miniNAS with 3 CM4s (one Jetson Orin Nano). I got two RPi4's one at my mother in law, one at my mother, allowing a VPN connection for tech support and also running Jellyfin with old content for them.

Personally, I still enjoy my Pi's (and no not all of them are on and used 24/7) however I also very much enjoy Proxmox and VMs. But the Proxmox machine is a Xeon... (HP MicroServer 10 Gen 10) the fan is loud af and difficult to replace with say a Noctua due to HP ingeniousness.
