AMD Ryzen 9 7900X test: A BANG of an intergenerational leap

Audio encoding

More aggressive power limits? Okay, but at a higher efficiency than Intel can do, AMD told itself while working on the Ryzen 7000 processors. And that’s how it really is, despite record-high clock speeds that are truly unusual for a new, unrefined manufacturing node. If this is just the beginning… In any case, not everything is rosy and AMD’s new processors have downsides that will need to be addressed in the future.

Audio encoding

Test environment: Audio encoding is done using command line encoders, we measure the time it takes for the conversion to finish. The same 42-minute long 16-bit WAV file (stereo) with 44.1 kHz is always used (Love Over Gold by Dire Straits album rip in a single audio file).

Encoder settings are selected to achieve maximum or near maximum compression. The bitrate is relatively high, with the exception of lossless FLAC of about 200 kb/s.

Note: These tests measure single-thread performance.

FLAC: reference encoder 1.3.2, 64-bit build. Launch options: flac.exe -s -8 -m -e -p -f

MP3: encoder lame3.100.1, 64-bit build (Intel 19 Compiler) from RareWares. Launch options: lame.exe -S -V 0 -q 0

AAC: uses Apple QuickTime libraries, invoked through the application from the command line, QAAC 2.72, 64-bit build, Intel 19 Compiler (does not require installation of the whole Apple package). Launch options: qaac64.exe -V 100 -s -q 2

Opus: reference encoder 1.3.1, Launch options: opusenc.exe –comp 10 –quiet –vbr –bitrate 192

  1. If I go a silent setup with the Ryzen 7000 series, I’ll get much lower performance, while still paying the full price. Lisa Su should pack some noise-canceling headphones in these boxes.

    1. This can be adjusted now. Youtubers have guides on how you can lower the temp without losing any performance. 61c Avg. the temps sit at now.

      Apparently they are designed to run at that temperature ,but like me i am not comfortable with that.
