RPI would be awesome for NAS if you could connect SATA somehow
Only maximum 4 Gbps shared by 1G ethernet, PCIe 2 and 2x USB 3.0? Thats even less speed than 2 harddisks.

#132The full specs and benchmark link: https://www.raspberrypi.org/magpi/raspberry-pi-4-specs-bench...
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.

#133I've always wanted to buy one of these and play with it for a few months, even though I'm null when it comes to electronics. But life just doesn't allow me the time. :(

#134Earlier quoted context omitted.
The cheapest maybe, but don't I need to watch for specs and DRM features and everything?
HDMI to micro-HDMI is just a straight passive adapter - only the physical shape of the port is different, and feature support isn’t really a thing. In this case it’s obviously done because the HDMI connector is annoyingly bulky if you want two of them, though I’m surprised a stacked connector wasn’t a better option.
Stacking is risky, because the end of cables might be unreasonably large, thus two might not fit on top of each other that close. Also HDMI cables tend to be pretty bulky, they might simply strain the board too much?
Or there were no cheap enough stacked port.

#135The book 'kubernetes up and running' had a description on how to set up a kubernetes cluster out of raspberry pies. I guess a setup with the new pies would look a bit more real.

#136Anyone know if you can connect dual 4K displays?
Yes, you can. But dual 4K only at 30 Hz. If using only one display, 4K at 60 Hz.
NOTE: Take this with a grain of salt, though, can't be completely sure if this is correct.

#137Would be an exciting upgrade for my wearable computer! Congrats RPi Foundation!
Re: Raspberry Pi 4
#138>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 chip…
1) They make a low cost computer where they've put significant work into making it more open software wise. Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones? 2) Maybe it's to do with the terms in which they get the camera module? I don't know but I don't see them selling the camera as interoperable. Your comment just seems to exemplify the phrase: "No good de…

I hope you realize that by "they" you mean the hardware vendor and by "freeloaders" you mean the vendor's customers.

#139The 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. Howe…
I imagine the wait must be agonizing! Why not just have a NFS server on your more powerful computer for the Pi to stream the file from? 100 Mbps is easily enough to stream any Bluray.
Can't speak for OP but I don't want my main PC on all the time if I'm streaming away from home.
Re: Raspberry Pi 4
#140> 4K! I'm very excited about these upgrades too (especially GigE), but as far as I can tell nothing on this news page specifies whether the Pi will also support HDR output as part of the 4K upgrade. That's most of the practical benefit of 4K - that 4K releases tend to come with HDR10 or DolbyVision support. Anyone know if we can expect HDR output to work? If I knew it supported that I'd be purchasing one right now to…
The Raspberry Pi 4 B uses ARM VideoCore IV. As far as I can find HDR will only come in the updoming VideoCore V. So no. No HDR yet.
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 performance.
