Why do people tend to dismiss the openness of the RasperryPi with completely unrelated things? This is the classic case of Whataboutism[0]. Just because you can't replicate the entire product in your garage, it doesn't mean that it is…

I don't agree with the parent but it isn't an example of whataboutism. He's taking issue with the stated aim of openess, with examples he feels aren't open.

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…

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.

RPI would be awesome for NAS if you could connect SATA somehow

The USB 3.0 ports should give 100MB/s (Benchmarks show up to +300MB/s), and you can mirror two disks for RAID-1. With 4GB of RAM, you'd even be able to use ZFS.

not these USB 3.0 ports. Connected with shared 4 Gbps, they only run at 4/5th, 1/2 or less of the full 5 Gbps speed.

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself. USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?! What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited! I'm setting up a VPN to hook this (when I get it) to my VPS and then do…

> I've been using the RPI2 as my HTPC/NAS at my folks

Could you provide some details? The USB-adapted ethernet & lack of wifi sounds limiting for a NAS.

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…

Con for me is still SD storage :-( At least now an SSD over USB3 should be reasonably fast

You don't have to boot off of the SD.

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…

> the Odroid HC2 could also - still - be considered

Even don't think about it - shitty support from vendor. They don't care about updates in general.

Maybe RPi developers deal with with some investors that way? (in order to attract more money)

The Raspberry Pi Foundation is a nonprofit.

How are you a non-profit if you pay a salary to you employees and allow your suppliers to make a profit?. They act as a 'low profit' company, but they do make profits.

Has anyone had success using an ARM based system for local development in Linux?

Yes, I use my R.Pi3 as a development server.

I run Nginx -> Postgrest -> PostgreSQL on the R.Pi, and it has served me faithfully for more than a year. It is blazing fast ( _for my needs_ ) and I can quickly replicate and setup another R.Pi if needed in a jiffy. I can't wait to port my setup to the new ARM64 R.Pi4!
