Intel's OSPRay Studio was enjoying faster render times with SMT enabled for AMD EPYC Bergamo while only having a small impact on the CPU power consumption.

👁 toyBrot Fractal Generator benchmark with settings of Implementation: TBB. EPYC 9754 2P: SMT On was the fastest.

👁 toyBrot Fractal Generator benchmark with settings of Implementation: OpenMP. EPYC 9754 2P: SMT On was the fastest.

The toyBrot mandelbrot fractal generator did enjoy significant speed-ups with SMT enabled on Bergamo.
