Watching the video, is like seeing a commercial for a PC many years ago. Only differences is the Raspberry's tiny size, small price and the few thousand times faster processor.

#162I'm happy that they're upgrading the pi, but it's not exactly lightweight computing in terms of power (they recommend a 27W PSU) or performance/watt (see: your cell phone) To me the charm of the raspi ecosystem was always in giving you a very low power, "always on, almost no power draw" linux environment. Oh well, I guess there's always the older versions or the zero for that.
At 27W that is a strong pass vs a NUC. If I go with a low power x86 NUC, I can run all software on it, and probably insert a SSD + additional RAM, for probably ~15W.
That'll be peak power draw though: you have to spec the standard power supply to cope with the CPU running @ 100% & simultaneously feeding the 1G ethernet and all the USB ports at max power.
Jeff Geerling measured 11W peak board power running benchmarks. Idle power was measured at 1.8W.
They claim it will draw less power than the Pi4 for the same workloads.

#163So a Raspberry Pi 27W USB-C Power Supply and they also showing an active cooler. Seems like this thing is running even hotter than the previous version. Btw am I the only one who hates to buy their power supply because the USB-C cable is not removable?
All laptop power supply with USB c have non removable USB c cables. Probably that no one can blame them for burning or low power with third party cables.
not all, for example apple's macbook power supplies have removable USB-C cables

#164What 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.

I think it’s hard to generalize that into a phenomenon. I have always bought 2 new raspberry pies with every release. I’ve used some and forgotten, unplugged some, given away some, broke some, and now they’re all used in some way. I bought them because I knew I’ll use them. I didn’t buy any other random toys or mini computing devices (even though they were alluring) because I knew I wouldn’t use them. There should be…
I dub it "phenomenonization".
I do recognize GP, though. In college, I was obsessed with Linux. Nowadays I have a Macbook, and like you, have an Intel NUC (running Windows). I really don't need a Raspberry. But boy, do I need to resist the urge to get one.

Yeah my intel atom NUCs run at 5W idle and 10W load and they're a ton faster than a pi 4. Probably a pi 5 too. It's not very impressive. And that's with a real SSD.
That’s not suppressing since the Pi is usually several process node generations behind.

#167Earlier quoted context omitted.
> Gigabit Ethernet, with PoE+ support (requires separate PoE+ HAT) isn't this just like the 4?
Just a shame they didn’t add actual POE without extra hardware.
PoE requires a few beefy components that would blow the board size (and BOM) up quite a bit, for a feature probably only 10-20% of users require.
I'm happy with a separate accessory, but wish they could've kept compatibility with the previous versions.

Re: Raspberry Pi 5
#169Interestingly the Pi 5 has moved most I/O like Ethernet, USB, MIPI and GPIO into a custom I/O controller chip called the RP1. It talks to the main CPU over 4-lane PCIe. They also have a custom PMIC (Dialog DA9091) with a built-in RTC and support for external backup battery. Everything else seems pretty standard.
> Interestingly the Pi 5 has moved most I/O like Ethernet, USB, MIPI and GPIO into a custom I/O controller chip called the RP1.
For cost-saving reasons, the I/O is located in the RP1 Southbridge (which has a larger process size) instead of the SoC. I had the opportunity to preview the Pi5 and have provided a detailed breakdown of the RP1's components [1]. In summary, what I/O functionalities does the RP1 manage? Essentially, it handles almost all of them.

#170I'm sad that there is no PR2040 PRU on board.
