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.
This is really a myth, they make a lot of pis every month and have done for a very long time. 99% of them go to industry instead of end users.
It was the same for any electronics during covid. If you didn’t have any volume buy, the manufacturers and suppliers didn’t give you the time of the day.
The supply chain is better now and there is some availability.
