Dude, people told you already in several threads, there's very little optimizations to be done when it comes to audio... and whatever optimizations are already in such programs, they work pretty much the same on Intel and AMD processors.
Whatever "improvements" you would do on audio encoders, it would only increase the speed by a few percentages at best, and nobody cares to invest a huge amount of time for so little benefit .
If you encode the audio track of a 2 hour movie in 10x real time speed (so basically finishing compression in 10 minutes), nobody cares to optimize some software to finish the job in 9 minutes and 30 seconds.
Nobody cares about OGG anymore, it's as good as "deprecated". It's replaced by Opus which is free and open source and produces better quality than MP3 or AAC at majority - if not all - of audio bitrates .
AAC is still worth using because it's used in DVDs and has good compatibility it's often used by Youtube and Apple for streaming audio. Whatever improvements you'd get between different codec versions would probably be psycho-achoustics (as in how to modify the sound to throw out some data for better compression, while tricking your ears into thinking it sounds good)
AC3 is old enough to have its patents expired so you don't have to pay licenses for it, MP3 also expired recently if I'm not mistaken, but the quality of AC3 is not better than MP3... not worth wasting time improving encoding speeds when there's something else better.
If you want something fast and best quality for a music collection, just use FLAC for archival and Opus for listening daily. Use a player like foobar2k and you'll be fine. And if you have a music player, try and see if Rockbox supports your player:

If you need speed at compressing FLAC, encode multiple tracks at same time, or use Cuetools.FLAC encoder that can use OpenCL and your video card to compress audio super fast.
Forget about MP3.
