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.

With no graphics card specific compilation to the ffmpeg, which among intel or AMD is better for executing

ffmpeg -i input -c:v libx265 -crf 26 -preset fast -c:a aac -b:a 128k output.mp4

Would tight integration between amd cpu + gpu help in this case?

Fyi. Currently i am using intel with cpu only mode for this and its pretty slow.

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
