A Look at AMD's Threadripper CPU Hardware Modes

Test Setup

 

 

The CPU was run in out-of-the-box configuration, meaning I didn't increase memory speeds or alter CPU speeds or settings past what the UEFI sets at default. The CPU was tested in five different modes. The first mode is 1950X Legacy Mode SMT ON/NUMA, which results in 8C/16T, uses local memory access (quad channel), and leaves SMT on (Gamer Mode in Ryzen Master).

 

 

The second mode is 1950X SMT OFF/UMA, which is 16C/16T with distributed memory access. The third mode is 1950X SMT OFF/NUMA, which is 16C/16T with local memory access.

 

The fourth mode is 1950X SMT ON/NUMA, which is 16C/32T with local memory access. The fifth mode is 1950X SMT ON/UMA, which is 16C/32T with distributed memory access, and it's also the default mode the CPU operates in (Creator Mode in Ryzen Master).
