The Rpi4 comes with a quad core ARM Cortex A72, up to 4 GB of RAM and a gigabit ethernet port, at a very low price of 35 $.
Raspberry provides Raspbian (a Debian derivative), an already ready distro for their products, so I put it on an sd card to boot it quickly.
I was looking at the syslog and I noticed that, uh, both the kernel and the whole userland are compiled as armv7, which means 32 bit ARM.
I know for sure that the RPi4 is 64 bit capable, so I refused to run a 32 bit OS on it. I get another sd card and I installed Debian on it. A lean and mean Debian compiled as aarch64, which means 64 bit ARM.
As soon as the 64 bit OS booted, I was curious to know how much it performs better than the 32 bit one, so I did some tests.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
