That's because of this: https://en.wikipedia.org/wiki/VideoCore https://en.wikipedia.org/wiki/VideoCore The rpi has hardware video acceleration even just a little bit, and the Celeron 1.4ghz laptop I had did not have any hardware acceleration of any kind. That was the difference really between my Phenom II X4 and the Ryzen 5 1400. Aside from obvious architecture differences, if my Phenom II had the video codecs built in, it'd have been plenty fast. There's more to CPU's than clock speed and basic architecture. Features matter.
