A Look at AMD's Threadripper CPU Hardware Modes

By: Steven Bassiri | Guides | Posted: Sep 20, 2017 10:20 pm

UNIGINE and 3DMark

 

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).

With NUMA mode seemed to increase overall score in FireStrike, and while Legacy Mode did heavily increase GPU score, it wasn't enough to make up for the decrease in Physx score. In Cloud Gate, Legacy mode increased GPU score by so much that it won overall score.

 

The two 3DMark benchmarks act like different types of games and reveal that in some cases, AMD's Legacy mode (Gamer Profile) really can increase performance, but in other cases, it doesn't. UNIGINE once again revealed that removing that die to die latency provides better gaming performance, even with the loss of half the CPU's cores. UNIGINE also seemed to prefer NUMA over UMA.
