Raspberry Pi 4 vs Pi 3 B+

So now that the Raspberry Pi 4 model B has just been launched, it may be worth checking out the differences against the previous latest single board computer from the Raspberry Pi foundation, namely Raspberry Pi 3 model B+.

Let’s get straight to the Raspberry Pi 4 vs Pi 3 B+ comparison table.

The Raspberry Pi Foundation has done a pretty amazing job here with adding the extra performance (CPU up to three times faster), and plenty of new features (4K, GbE, USB 3.0..) while keeping the same price tag for the board with 1GB RAM. Some of the features I don’t see advertised and are present on some of the competing boards include HDR (High Dynamic Range) and VP9 video decoding.

Now some of you may ask: “Wait? A comparison without benchmarks? Where are the benchmarks?” To which I reply those are coming as I’m expecting a Raspberry Pi 4 board in a few hours…

Another difference is with SD cards. The new model supports switching to 1.8V and as such SDR104 seems to work (doubling both random IO and sequential transfer rates from 25MB/s to 50MB/s).

so what sd card do you suggest? thanks

SDR104 was BS. It’s DDR50 but still twice as fast as before (without the need to ‘overclock’ the SDIO bus).

On the official techspecs is says SDR50, SDR104 is not mentioned:
“The Pi4B has a dedicated SD card socket which suports 1.8V, DDR50 mode (at a peak bandwidth of 50
Megabytes / sec). In addition, a legacy SDIO interface is available on the GPIO pins”

https://libreelec.tv/2019/06/libreelec-9-2-alpha1-rpi4b/ LibreElec guys suggest that both HDR video and HD Audio bitstreaming are on the road map and have hardware support. I would be surprised if HDR10 PQ ST.2084 output wasn’t possible (if not supported OOB now) – and DTS HD MA/HRA and Dolby Digital Plus/Dolby True HD similarly. https://forum.libreelec.tv/thread/17698-libreelec-leia-9-2-alpha1-with-raspberry-pi-4b-support/?postID=121493#post121493 Forum thread suggests static HDR (HDR10/HLG) will be supported but not licensable dynamic metadata systems like Dolby Vision. Not clear about Atmos (my understanding is that it’s usually inherent in DTS HD MA and Dolby True HD passthrough that DTS:x and Atmos extensions also pass? But I may be wrong)

From LibreElec video seems they need kernel work. Also wonder how security compliant is the hardware for high resolution video playback from official services, not pirate rips.

LibreElec and Kodi exist for Rips.

Atmos will be supported for pass-through.

Any news/ifo about the VideocoreVI? Like the bootcode, VPU and ISP? I’ve read that now the bootloader should turn on the ARM cores and then the GPU side. So the RTOS part should be removed. This should means that the GPU *should* be directly controlled from the ARM side? So probably the ISP and DSI could be configured from the linux side bypassing the videocore fw? This will make the RPI more interesting. I stopped to buy rpis back with V2, when they told the community that they will release the sources and they didn’t (Olny the 3d part) We… Read more »

Missing port for eMMC storage module from my wishlist.

Also read that Rpi4 doesn’t yet support USB boot.

Well, the USB controller is now behind PCIe so they need to put both a PCIe and a new USB driver into the EEPROM. They plan on adding netboot first, then USB later: https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md

Raspberry Pi 3 B+ 1x micro HDMI, typo?

My 3B+ has the full size HDMI.

Another difference is the dimensions seems to be a little bigger 88 mm × 58 mm × 19.5 mm.

I heard eben upton saying same bluetooth chip software upgraded to 5.0 so 3b+ will be upgraded too.

Some sort of disk I/O would have been great – eMMC or eSATA

And this new SoC is 28nm, instead of 40nm which were on 3B+
