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.
That’s the problem. They’re always out of stock.

You’d even be hard pressed to find one at a Micro Center or some other physical store.
I just managed to get one like a month ago. After watching all the retailers I could find for like 2 years. Eventually I found a site that aggregated them to make it easier but it was Still like 3 months before I caught someone with stock in time to buy it. Figures the next one would come out right after all that…
