The information embargo on Z890 motherboard tests (and also Intel Core Ultra 200S/Arrow Lake CPUs) is over. We kicked off our tests with an in-depth analysis of the MSI MAG Z890 Tomahawk WiFi motherboard, which also sheds light on the features of the Core Ultra 7 265K CPU. Primarily though, this will now be about the Z890 Tomahawk, which in some places has some major changes from its last generation.
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

Thanks! Fixed. 🙂
