I wish they'd integrate PoE (without the hat). That chip they're using appears to support it. http://www.trxcom.com/Product/product/id/353.html

I guess they needed to drop that and a lot more to hit $35 price target.

Also, they probably ran out of space on the board

I would love to hear the kind of stuff everybody is using Raspberry Pi for. Is anybody using them in museums or for digital signage?

For those wondering about using it for development, it can run Anvil's web IDE: https://anvil.works/blog/raspberry-pi-4-web-ide

Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: https://www.hardkernel.com/shop/odroid-hc2-home-cloud-two/ - Half the RAM but double the cores. I'm waiting for some benchmarks to see if the RPi4 is faster and by how much. - Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB/s for the whole transfer. - Not…

I have been using Odroid XU4 for home server (home assistant), personal CCTV, controls IR blaster and other sensors for years, still running perfect without rebooting for months. I also have Pi 3 for Pi Hole, but honestly my Odroid XU4 is more stable than Pi 3.

That's pretty clever. You should marry her.

Marry his wife ? Again ?

I often see comments about this product piggybacking on other things' visibility here on HN. It is closed source too. Can you please put your ads somewhere else?

Does anyone know it’s graphics card specs ? How big of a neural net can I run? Does it Raspi4 have a tensor flow backend ?

At the power usage if Raspi4, how big of a solar panel and battery do I need to have a always sentient computer out in the wild that can recognize and count things ?

That's great, but if you need crypto (because you have LUKS storage and send AES encrypted data over the network, like in a usual NAS case), A53 with aes instructions may be faster than this A72 without one. And so far it seems these cores don't have aes instructions.

Seriously? They left out Cryptography Extensions from the RPi4 SoC? Any source / references? http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.... Edit: Ouch if this turns out to be true... https://www.raspberrypi.org/forums/viewtopic.php?t=243410 Edit 2: Ah, also RPi3B and 3B+ didn't have those extensions. Oh well. Edit 3: Just tested my bog standard RPi3B+ running Raspbian. It could do "openssl speed -ela…

Nice investigation!

The VideoCore 4 (fuck the roman numerals, for exactly this reason) can not output 4k and it is also not a ES 3.0 capable GPU. So this must be a 5 or 6.

I'm crossing my fingers here. This is really something they should have put in the specs if it's supported. With 10bit decoding and Rec. 2100 [1] support, this would make a fantastic platform to build a media center on. I'd certainly upgrade from the Pi 3 even though I don't currently have a 4K television. [1] https://en.wikipedia.org/wiki/Rec._2100

What are the odds that this will support 1080p streaming with Plex? I've tried Plex on a Pi 3 using a Roku as a player with 1080p and it's a complete failure. Plex tries to encode everything even if native playback to the Roku is possible using the Roku media player.

The spec table says VideoCore VI. I really hope that is not a typo. I suspect it really is a VC6 because 2x4k is a big bump in pixel count and without a corresponding bump in fill-rate, perceived performance will drop. [edit] looking at the benchmarks it's a modest boost. Now about twice the FPS of a PI-2 for Quake3 at equal resolution. Be interesting to see if something with more complex shaders changes the relative…

VI == 6 IV == 4

6 IV is 24
