AMD says
Game Mode is a new feature in AMD Ryzen™ Master that reconfigures the platform in two key ways:
• It temporarily disables half of the CPU cores, which turns the AMD Ryzen Threadripper 1950X into an 8C16T device (like the AMD Ryzen™ 1800X) and the 1920X into a 6C12T device (like the AMD Ryzen™ 1600X). For the truly technical, this is a 4+4 CCX configuration on one die. This ensures the game encounters the number of cores it was truly designed to handle. Please note that Game Mode does not disable SMT.
• We tell the OS to use a Local Mode (NUMA) memory, which keeps a game and its memory footprint inside one CPU die and the locally-connected DRAM. This minimizes several key latency points in the system, which most games love.
