From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

none, you aren't using gpu, just whatever cpu is the fastest. if you want gpu acceleration you have to specify it. and keep note gpu acceleration is less efficient then cpu so your files will be bigger. though at preset fast it might actually be pretty close
Yes this is indeed what I said. but well calling gpu encoders "worse" isnt really fair, it's all trade offs, they for sure have worse efficiency as we both said, but their speed is significantly faster usually. I would say that doesn't make the encoder "worse" just different.
So what you are saying is its better to run on cpu alone?
Running on cpu will give you better quality and (maybe) smaller output file size, but will take longer.
Everything's a compromise and it all depends on what matters more to you
Better quality:Compression ratio you can easily get better quality out of a gpu then a cpu depending on your settings, but it will rarely be better quality AND compression unless you have a quite slow CPU and cant run a sensible preset
when possible yes, sometime sits not possible, and it will be better to run on gpu alone
