The 65mm x 30mm board features a quad-core 64-bit Arm Cortex-A53 CPU, clocked at 1GHz.

I remember my first computer, an Amiga 500, had a 7.16 MHz clock.

The 7.16 MHz clock was double the color chroma frequency in NTSC video. What 3.579545 or such

... I remember my first computer, an Amiga 500, had a 7.16 MHz clock

Mine (first) was one of the original IMB PCs. It's clock ran at 4.77 Mhz. (It cost just over $3000) - (This was in 1981, mind you, when I was a Junior in High school.)
I even shelled out the extra dollars for a SECOND 360K Full height 5 1/4 inch floppy disk drive! And as a Christmas gift for my little brother a few years later I bought him a Commodore VIC - 20.

And today I am typing this post on a Kamrui Quad-Core Celeron
with 8GB of RAM and 256GB Solid State Disk that cost me $277.

Time and technology marches on....
