In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular, day-to-day use case for many end users, to provide portability and storage of their digital audio content. LAME is an open-source mid to high bit-rate and VBR (variable bit rate)
MP3 audio encoder that is used widely around the world in a multitude of third party applications.
In this test, we created our own 223MB WAV file and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.
The AMD Ryzen 9 3950X doesn't fare too well in the single-threaded audio encoding test, where it barely edged out the previous-gen Ryzen processors and trailed all of Intel's offerings. Its superior multi-threaded scaling, however, significantly speeds up the encoding process and it only misses the mark set by the fastest Intel processors by a couple of seconds.

X265 Benchmark |
Video Encoding Test |
|
The multi-threaded HWBOT x265 Benchmark is based on the open source x265 encoder that leverages modern CPU instructions to speed video encoding. We tested the CPUs represented here with the 64-bit encoder using the default 1080p workload.
The AMD Ryzen 9 3950X rocked the x265 video encoding test. It takes top honors when running in full-power mode and second place when operating in ECO mode, besting Intel's 18-core Core i9-9980XE and dusting the Core i9-9900KS in the process.

Y-Cruncher |
MT Pi Calculator |
|
Y-Cruncher is a multi-core-capable tool that calculates the value of pi to a specified number of digits. In this case, we ran the tool on all threads and had the application calculate the value of pi to 1 billion digits. The values below are the time required to perform the calculation expressed in seconds. As a result, lower values indicate better performance.
The Core i9-9980XE's larger pool of quad-channel memory (and resulting memory bandwidth advantage) give it the edge in this benchmark, but the Ryzen 9 3950X outpaced the rest of combatants, including the previous-gen 16-core Threadripper 2950X.
