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. 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.

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? Esse…

Just like a 1970s IBM mainframe ;)

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.

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 agree with you about dev boards but I think their post was focused on things like used NUCs or other small x86 machines that are only marginally larger than a Pi in an enclosure and include literally everything you'd want (enclosure, pwa fan, SATA SSD, NVMe, wifi, etc.) and the software support is there (linux / windows).

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.

Power consumption is a consideration though depending on your use case and setup. A Pi 4 draws about 3W on light load and these G3 Minis take 10-12W. Of course if you deck out a Pi 4 with a SSD and a fan, it'll come much closer to the G3 Mini in terms of power consumption.

The Dell wyse 5070 idles close to 3-5 watts. A bit more than the pi, but pretty close. It's older now, can be picked up cheaper than a pi off eBay. DDR 4, sata m.2, on board emmc flash. M.2 a-key for WiFi. Max 16GB ram.

When you throw in m.2, lots of ram, all that IO eats power. So the minimum idle power creeps up. Arm boards too.

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, electrical compatibility, software compatibility, DO provide the value the "Raspberry Pi" brand offers if its competitors offered it.

What I'm saying is, if Espressif brought that new ESP-branded 32bit thing in the Pi 3 mounting dimensions and onboard eMMC and 1/5th performance at $35+9%, that kind of thing could outsell Pi 5 at this rate, and I wouldn't mind watching that happening.

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 use a Qotom q750g5 for my router / firewall with OpenWRT. It is absolutely fantastic, and replaced an aging Ubiquiti Edgerouter Lite 3.

It may be that whatever is currently bottlenecking RPi4 production isn't relevant to RPi5.

Through hole components resulted in previous Pi's being slightly slower to manufacture, the Pi5 only uses surface mount components which should increase Sony's build cadence.

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.

Agreed, burns so much time messing around with arm and the limited IO suite.

Given that they made custom silicon for the IO module, I'm disappointed that they didn't include a couple PIO cores in there. It would've been great to be able to use the GPIO pins to drive serial LEDs, as extra uart peripherals, or for any of the numerous other things people have developed for the RP2040 PIO.

The RP1 has one PIO core (4 state machines) https://www.raspberrypi.com/news/introducing-raspberry-pi-5/...
