AMD has implemented BIOS switches and software switches in order to better support and control the NUMAness of Threadripper. By default, Threadripper actually hides its NUMA architecture. AMD instead runs Threadripper in a UMA configuration: a uniform memory access system where memory is sent to any DRAM and the return is variable in latency (e.g. ~100ns averaging between 78ns and 133ns) but focusing for a high peak bandwidth. By presenting the CPU to the OS as a monolithic, single-domain design, memory bandwidth is maximized and all applications (NUMA-aware and not) see all 16 cores as part of the same CPU.
So they still support node interleaving.
