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!
- moffkalast 3y agoSide 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.
- bmicraft 3y agoGPIO is now connected to the RP1 I/O controller which is on a 40nm process, so that should actually be an improvement

- spatular 3y agoOrange Pi 5, "plus" version also has 2gen 1-lane pci-e (M.2 wifi), and 3gen 4-lane pci-e (M.2 SSD) and 2x2.5Gbit ethernet. 8nm, pretty power efficient. I've measured it to run at 0.7A@5V idle and 1.2A@5V with all 8 cores loaded with md5sum /dev/zero; iirc it had 1 ethernet connected, no other periphery. Running on Armbian.
- doubled112 3y agoI have the non-plus and have been pretty happy with it. A lot more computing power than the Pi 4 and older home server it replaced. The M.2 slot was an absolute game changer. Real onboard storage is a must. It runs a few low resource VMs in the garage and I almost completely forget it exists.
- pbronez 3y agoHow is the software support? That’s the main thing keeping me on rPi. I tried Pine64 and it was terrible. Never could get my PineBook Pro to boot reliably.
- doubled112 3y agoThere are always little things. As far as I know, desktop works pretty well and there are people running PS2 emulation on it, which has always been super heavy. arm64 has come a long way for that use case. It's been solid as the VM host so far. I wrote an Armbian SD card and it just worked. Once a VM is booted though, many things become irrelevant outside of arm64 support. I haven't tried again since February, so there's a decent chance my issues are fixed, but ZFS wouldn't build and VLAN support was disabled for the NIC. Not blockers, but it did make me rethink some ideas I had.
- ac29 3y agoAlder Lake N (N95, N100, etc) is built on a 7nm class process. Many of those systems could be considered SBCs (SoC/RAM/Storage is often all on a single board). Those CPUs are low end for x86, but much higher end than a typical ARM based SBC.
- InvaderFizz 3y agoThe N100 is quite good all things considered. It generally beats an i5-6500t in pretty much anything while having very low power draw and all the newest media engine encoders.
- fulafel 3y agoYou'd be surprised how low-end the average chip with ARM core(s) is.
- YetAnotherNick 3y agoYou'd be surprised to know how hot the RPi gets. My Rpi CPU is basically untouchable because of temperature even when only desktop is running idly.
- rldjbpin 3y agoprocess node only matters that much when you are dealing with the latest system architecture. whether you compare with rockpi's offering or with apple, A76 is a design from 2018.
