Article says, "The Raspberry Pi 4 is the ultimate microprocessor." No, not really. There are many alternative SBCs available that either outperform the Raspberry or will meet specific use cases better than the general purpose Pi 4. One example, in terms of raw power, is the Orange Pi 5. Phoronix reports "Across 169 different benchmarks I ran with the Orange Pi 5, this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." No surprise, the Orange Pi's RK3588s 8-core CPU is far more powerful than the Pi's BCM2711 quad core CPU -- even on single threaded apps.

I started out with a Ras Pi 3 years ago and it was excellent as a first time starter board. The online community support and online resources are excellent. But now I use alternative boards like OrangePi or FriendlyElec as I prefer Armbian over the Raspberry Pi operating system.
