Four years after the Raspberry Pi 4 shipped, today the Raspberry Pi 5 is launching with a much improved SoC leading to significant performance gains.
The Raspberry Pi 5 is designed to deliver a 2~3x performance improvement over the Raspberry Pi 4. The Raspberry Pi 5 features a quad-core Cortex-A76 processor that clocks up to 2.4GHz, compared to the four Cortex-A72 cores found in the Raspberry Pi 4 that only clocked up to 1.8GHz. The graphics are also much-improved with now having an 800MHz VideoCore VII graphics processor over the VideoCore VI graphics with the Raspberry Pi 4. The Raspberry Pi 5 is capable of driving two 4K @ 60Hz displays and features 4K @ 60 HEVC decode hardware capabilities.
Also interesting with the Raspberry Pi 5 is that it features in-house silicon in the form of the RP1 “southbridge” used for much of the board’s I/O capabilities. This southbridge should yield faster USB I/O along with other I/O bandwidth upgrades like a doubling of the peak SD card performance. The Raspberry Pi 5 also features a single-lane PCI Express 2.0 interface for improved connectivity.
The only problem is the shitty support they have. Just bought an orange pi zero 3 and can’t find any documentation for using the gpios
You can’t find a schematic for the pins?
Well, maybe if I was an experience coder capable of writing my own libraries that would help. Even still, this must be a new board, the documentation for it is abysmal. On the opi forums people are asking what gpio libraries work on this board, and the answer seems to be, well you will have to write you’re own for now, ok, but not all of us are at that level. I didn’t realize this was such a new board when I bought it, and support on the off brands is known to be much more sparse. I have just finished my second animatronic halloween decoration for my yard, and bought this because I can’t get any more rpi’s at the moment. With rpi, there is a great libraries to work with, and tons of good documentation on how to use them. It’s great to pump out cheap alternatives, but without software and documentation support, they aren’t really that useful.

If for nothing else, probably to be able to control it or turn it on or off based on other conditions remotely. But you can do that with an esp8266 too.
