Stargate Digital Audio Workstation benchmark with settings of Sample Rate: 96000, Buffer Size: 512. 12c DDR5-6000 was the fastest.
Stargate Digital Audio Workstation benchmark with settings of Sample Rate: 96000, Buffer Size: 1024. 12c DDR5-6000 was the fastest.

The Stargate digital audio workstation software performed the same regardless of the additional memory channels.

Timed Godot Game Engine Compilation benchmark with settings of Time To Compile. 12c DDR5-6000 was the fastest.
Timed Linux Kernel Compilation benchmark with settings of Build: defconfig. 12c DDR5-6000 was the fastest.
Timed Linux Kernel Compilation benchmark with settings of Build: allmodconfig. 12c DDR5-6000 was the fastest.
Build2 benchmark with settings of Time To Compile. 12c DDR5-6000 was the fastest.

In the code compilation benchmarks was minimal difference between eight and twelve memory channels when compiling one codebase at a time with a make job for each CPU thread.

Liquid-DSP benchmark with settings of Threads: 64, Buffer Length: 256, Filter Length: 57. 8c DDR5-6000 was the fastest.
Liquid-DSP benchmark with settings of Threads: 128, Buffer Length: 256, Filter Length: 57. 8c DDR5-6000 was the fastest.
Liquid-DSP benchmark with settings of Threads: 192, Buffer Length: 256, Filter Length: 512. 12c DDR5-6000 was the fastest.

With the Liquid-DSP digital signal processing software there wasn't any observed benefit either in this case.
