Minimum 2x performance over previous gen(s) on every test with only ~1W extra power draw. That's seriously impressive!

  they are better, modern, more efficient and cheaper CPUs in 2019 the fact that they decided to go with a 2015 inefficient one is kinda strange
  - frabert 7y ago
    Non if you consider the need of developing open drivers for them
  - imtringued 7y ago
    Modern SoCs cost more than $35.

      They're possibly thinking about something like the Amlogic S922X. A 12nm SoC with Quad A73 and Dual A53, its definitely more modern and more efficient, though "better" is pretty subjective. As implemented in the Odroid N2 [0], its not cheaper at $79 with 4GB RAM, compared to Raspi 4's $55 (or $63 and $45 for 2GB, respectively). Hard to say if they cut the board down to remove all the things Raspi doesnt support and scaled up to Raspi scale if they could match the price. If not, it'd likely be close.

Missing: SD card performance benchmark. Previous models could only read about 20 MB/s or so, while the modern SD cards can do 10x (maybe even more) that. Is there any improvement in this? It's pretty important as RPi usually boots off it.

  You can boot off a USB drive.
  - lloeki 7y ago
    IIRC bootloader and kernel have to be on SD card so you always boot from there but can easily pivot to the USB drive for the root partition.
    - dchest 7y ago
      Nope, it can boot from USB without SD card.

        Correction: it seems like RPi4 doesn't boot from USB or Ethernet yet; they will release a firmware update to turn it on. "Support for these additional bootmodes will be added in the future via optional bootloader updates. The current schedule is to release PXE boot first, then USB boot." https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md https://www.raspberrypi.org/documentation/hardware/raspberry...

      Not any more! As of the Pi3 you can even netboot! https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/net_tutorial.md https://www.raspberrypi.org/documentation/hardware/raspberry...
