  • Yep.

    “In 1978, the Cray 1 supercomputer cost $7 Million, weighed 10,500 pounds and had a 115 kilowatt power supply. It was, by far, the fastest computer in the world. The Raspberry Pi costs around $70 (CPU board, case, power supply, SD card), weighs a few ounces, uses a 5 watt power supply and is more than 4.5 times faster than the Cray 1”

    Raspberry Pi ARM CPUs - The comment above was for the 2012 Pi 1. In 2020, the Pi 400 average Livermore Loops, Linpack and Whetstone MFLOPS reached 78.8, 49.5 and 95.5 times faster than the Cray 1.

    AMD APUs have Video Coding Engine / Unified Video Decoder, while Intel CPUs have QuickSync. FFMPEG’s hardware page says that AMD support is incomplete.

    You may want to ask over in !datahoarder@lemmy.ml . This topic often came up back on Reddit, and the general vibe I got was that most people prefer QuickSync. Intel may not be great in a lot of areas, but they are a beast in video encoding/decoding. That being said, I use a Ryzen APU and it’s perfectly fine. There are way more important things to look at when choosing a CPU.

    If your performance is slow, I would check your CPU is listed on the chart I linked above. Not all CPUs support all codecs.

    Edit: If your CPU doesn’t support the codec, it will still work, it just won’t be accelerated.
