A Look at AMD's Threadripper CPU Hardware Modes

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

Resident Evil, Tomb Raider, GTA:V, Ashes of Singularity

 

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).

Resident Evil really likes the Legacy Mode within the Gamer Profile in Ryzen Master. NUMA mode also helps with Resident Evil 6. We see that GTA:V also likes the Game Profile as well. Rise of the Tomb Raider shows that the Gamer Profile (with Legacy mode) does well at lower resolutions, however, at 4K, both average and minimum frame rates were slightly higher with SMT OFF and NUMA mode.

 

Finally, we have Ashes of the Singularity: Escalation, and to be clear we used v2.4, which is newer than v2.3 used for the launch review. In fact, I couldn't even get Ashes to work with Gaming Profile (Legacy mode) with the previous version, but now it does work fine. However, while Ashes loves cores, it seems to dislike NUMA mode, and I even saw reverse scaling with SMT OFF and NUMA mode.

 

All of this means that your game might or might not like hardware mode changes, but the good news is that Gamer Mode is almost always either better or worse than default mode, so it's easier to pinpoint which is better.
