The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck in one’s home network. I know that the Pi was invented as an educational product, but thanks to the Linux distribution OSMC it is commonly used as a media center for playing films, music, TV, etc.

I have had gigabit internet for a few years now, and every day on average, I torrent a Blu-Ray image onto my main computer. However, subsequently moving the Blu-Ray to my Raspberry Pi 3 media center is always slow on two counts: 1) ethernet from the router to the Pi was limited to 10/100 speeds, and 2) the Pi could push large files to an attached hard drive only over a USB 2.0 port. Consequently, on a Raspberry Pi 1–3 it takes an hour just to move a high-definition file around one’s home network! On a Pi 4, it looks like one can just put the torrent client directly on the media center.

My first reaction to the specs:

Pros:

+ USB 3: Very nice! Finally a pocket-sized, fast USB host.

+ Dual HDMI: Could be useful as a projector computer.

+ 1.5 GHz: Good, it might be fast enough for some real work.

+ Gigabit Ethernet: Excellent for those using it as a NAS.

+ USB-C for power: Not surprising, it's the standard now.

Cons:

- MicroHDMI: Incompatible with the 800x480 HDMI 3.5" screen [1]. Also different again to the MiniHDMI on the Pi Zero (will there be a new Pi Zero soon? Who knows.)

- Power consumption! They recommend a 15W power supply, which means I'm pretty sure this won't run on batteries.

I’m not very familiar with the hardware here but could someone elaborate on why this seems to be such a big deal that there are four versions of the announcement trending on the first page?

Every year we upgrade our autonomous sailboat controller to the latest Raspberry Pi. This year we face a situation to choose from Jetson Nano and RPi 4. Even the decision is hard to made, now is an exciting moment for robot makers.

>Are you still using VideoCore?

>Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less.

This stated intention and rpi.org's actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1]

Secondly, why was rpi.org caught adding DRM chips to their optional camera addon board? [2]

[1] https://www.raspberrypi.org/documentation/hardware/raspberry... Note the nonsensical, incomplete nature of these schematics, and the complete absence of details such as the USB3 ports, and most of the SoC's connections.

They remove all the bottleneck from the previous generations making it more interesting for networking and desktop use.
