The more efficient Alder Lake processors with TDP/PL1 35–65 W are out. We are, of course, ready, and for a perfect overview we have complete tests of the Core i5-12400, i.e. the successor of the most popular models of the past generations. You can compare this processor in all aspects not only with them, but also with the Ryzen 5 5600X . It looks like this processor will sell like hot cakes.
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








The comparison of the Core i5-12400 against the Ryzen 5 5600X was especially interesting, especially with the focus on gaming performance per euro. It really looks like Intel found a strong value option.
