Re: Raspberry Pi 5
#82One thing that keeps these SBCs from being super useful and differentiates them from x86 computers is I/O. More PCIe lanes would've helped here.
But I guess this PCIe connection is at least officially accessible rather than being used up by internal adapters?

#83> 4Kp60 HEVC decoder This is game changer as TV box.
Good point H265 support is badly needed these days
Re: Raspberry Pi 5
#84I'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.
Did you read the blog post? :) "Raspberry Pi 5 consumes significantly less power, and runs significantly cooler, than Raspberry Pi 4 when running an identical workload. However, the much higher performance ceiling means that for the most intensive workloads, and in particular for pathological “power virus” workloads, peak power consumption increases to around 12W, versus 8W for Raspberry Pi 4."

#85Out of curiosity, does 5V/5A USB-C changer common? All of my USB-C Chargers has 5V/3A only.
5V/5A means at least 25W. Plenty of chargers at that level and above on Amazon.
Re: Raspberry Pi 5
#86Only quad core, no 16gb or 32gb ram option and pcie only available through a hat (and possibly slower than the usb3 port)? I was expecting a bit more to be honest.
And only 16nm. Imagine what you could do with even a budget smartphone chip with modern 5nm tech
Re: Raspberry Pi 5
#87anyone could tell me how did you use raspberry pi?

I also wired up my garage remote to it, so I can hit a web page to open up my garage.

#88Power button included - interesting.
Re: Raspberry Pi 5
#89I'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.
What do you mean with vague information? There is an entire blog post describing the product: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/
This is pretty bad:
"Does Raspberry Pi 5 need active cooling?
"Raspberry Pi 5 is faster and more powerful than prior-generation Raspberry Pis, and like most general-purpose computers, it will perform best with active cooling. The Raspberry Pi Case for Raspberry Pi 5, with its integrated fan, is one way to provide this."
They pose a question themselves, and don't even answer it. Of course something will perform best with active cooling. Does it need it?
I don't need this wishy-washy marketing language from Raspberry Pi.

#90> PCIe 2.0 x1 interface for fast peripherals (requires separate M.2 HAT or other adapter)
This could make it appealing for a low-power server, like a home NAS. In previous models, disk I/O had to be over USB, which imposes more CPU load than native SATA, along with various unpleasant quirks typical of USB-to-SATA bridges.
Too bad it's only one lane (assuming that's what they mean by x1), but I think that's almost enough to saturate a SATA bus, so it should nevertheless be useful where NVMe speeds aren't needed. I hope it's implemented well.
