These perform way better and have similar efficiency, too. Case, power supply, cooling, and storage are all included too. If you don't need GPIO then you don't

These perform way better and have similar efficiency, too. Case, power supply, cooling, and storage are all included too. If you don't need GPIO then you don't need a Raspberry Pi. If you do then consider using a microcontroller (Pi Pico, ESP32, etc.) first.
