Raspberry Pi 4
#1
This looks a proper upgrade:

https://www.raspberrypi.org/products/ras...4-model-b/

Some highlights:

Gigabit ethernet
USB 3
Dual micro HDMI output
Up to 4gb RAM

Code:
Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
1GB, 2GB or 4GB LPDDR4-2400 SDRAM (depending on model)
2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
Gigabit Ethernet
2 USB 3.0 ports; 2 USB 2.0 ports.
Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
2 × micro-HDMI ports (up to 4kp60 supported)
2-lane MIPI DSI display port
2-lane MIPI CSI camera port
4-pole stereo audio and composite video port
H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
OpenGL ES 3.0 graphics
Micro-SD card slot for loading operating system and data storage
5V DC via USB-C connector (minimum 3A*)
5V DC via GPIO header (minimum 3A*)
Power over Ethernet (PoE) enabled (requires separate PoE HAT)
Operating temperature: 0 – 50 degrees C ambient
A higher ram option with 265 hardware processing makes it very tempting.

looks promising, but didn't liked the micro hdmi ports, now we need a new cables :\

Can just use a dongle type converter. I have one, think it cost 2 or 3 quid.

No SATA support helas, but hey... not everyone will use it as an office pc replacement.
I hope USB booting will be implemented soon. Smile

As it's an embedded SBC (Single Board Computer) it would make more logical sense to put an eMMC storage module slot/port on it for embedded storage

https://en.wikipedia.org/wiki/MultiMediaCard#eMMC

eMMC storage has many but not all the benefits of SATA-based SSD, however more important for embedded devices; eMMC is small and relatively cheap.

Regardless I too would very much like to see future Raspberry Pis get a storage port for local storage that is a better local storage option than SD-cards.

It is not about speed (where eMMC cannot compete against SATA SSD), but SD-cards have a horrible tendency to get corrupted when eMMC does not.

And whats audio passthrough? For Dolby Atmos, is there are some option for this?

Hopefully this gives us proper 4k playback now that we have both h265 and gig ethernet and the USB 3 helps if we are able to use it for storage. Has the PI's never been able to boot from the USB ports? I don't own one but the Pi 4 or 4 b might be my first now that they got such a MASSIVE spec bump over the older ones.

The Pi 3B and 3A+ and 3B+ can boot from USB (and Network with the Bs) and I think the current Pi 2 B that is based on the same SoC (the original Pi 2 B SoC was EOLed).  Initially you had to boot from a Micro SD card to get to the OS to blow a one-time fuse in the SoC to enable it, but I think with the newest ones it's enabled out of the factory?

According to LibreElec blogpost here https://libreelec.tv/2019/06/libreelec-9...ha1-rpi4b/
Quote:The 4B now uses SPI flash for the bootloader. Current firmware supports SD card boot only – Network and USB booting are still on the Pi Foundation to-do list.

Looks like 1080p support (including HEVC/h.265 hardware decode) with audio the same as the Pi 3B+ is currently supported - with ongoing work to support 4K, HDR and HD Audio passthrough. The speed at which Pi developers work mean that it's likely to arrive relatively quickly I'd guess, particularly once more boards are in the wild.

Good (non-Kodi) review here too.

USB boot is already available on the Raspberry Pi 3B, 3B+, 3A+ and Raspberry Pi 2B v1.2 models so would be very surprising if it was not available in Raspberry Pi 4 as well

https://www.raspberrypi.org/documentatio...des/msd.md

You will need a compatible and prepared USB Mass Storage device and on previous models to Raspberry Pi 3+ you need to set the USB boot bit via booting to SD card once

https://www.raspberrypi.org/blog/pi-3-bo...rage-boot/

If you want a very stable Raspberry Pi setup from a hardware point of view use the original power-supply and boot to a SATA SSD harddrive that is inside a compatible USB enclosure or USB SATA Hard Drive Adapter

Does the Raspberry Pi 3+ and/or Raspberry Pi 4 have the drivers and hardware to decode and output HDR10 Media Profile (10-bit High-Dynamic-Range color) in HEVC encoded video at any resolution at all?

Not asking for 4K HDR10 video, but even just 1080p HDR10 video?

I know, I've been using it for a while now for running Raspbian and LibreELEC off an external SSD. Wink

that's what I would like to know as well. For me personally this has been the biggest flaw of the previous generation and ultimately resulted in being a dealbreaker for Kodi use.

Regardless exciting announcement this morning.
