Testing Ryzen 7 3700X OC SMT: On vs Off With RTX 2080 OC In 8 Games Shows Unexpected Results

Simultaneous Multi-Threading or Hyperthreading is meant to utilize all the threads rather than physical cores alone. It actually removes a hardship from cores by allowing threads to work. There were many SMT: On vs Off tests of Ryzen 3000 processors. Mostly high-end Ryzen 9 lineups get testing challenges. This time we have a chance to see test results of Ryzen 7 3700X at 4.3GHz boost clock. When SMT is on 16 threads work simultaneously. While it is off only 8 are on the work. It is highly expected that the frame rate may increase if SMT is off. We shall see that referring to tests of famous Youtuber called Testing Games.

Metro Exodus makes Off version have higher average FPS by removing 8 threads and giving more work to cores.

Rainbow Six: Siege brings 32 extra average FPS to the switched-off SMT CPU.

Only by 5 average FPS higher Off SMT gets a victory over switched on SMT in Assassin’s Creed Odyssey gameplay.

Surprisingly, Battlefield 5 did not give a triumph to switched Off SMT.

GTA 5 barely shows that turned off SMT has 6 points higher average FPS than switched off SMT.

Watch Dogs 2 became very strange game when SMT enabled CPU gets 3 average FPS higher than turned Off SMT

Hitman 2 gave interesting results by giving a victory to switched on SMT.

The Witcher 3 has almost similar results of both. Only 2 points could make turned off SMT win here.

The results from 8 games are different but overall high results go to SMT – Off CPU. Multi-threading is effective in making the processor live longer by delegating the work of physical cores to multiple threads.

I have also experience that most of the games runs better with SMT Off with AMD processors.
