Fig. 4: Comparison of GPU and estimated SPU performance.

a Time to solution to obtain Gaussian samples for dimensions ranging from 100 to 10,000 for an A6000 GPU (black squares) and estimated for the SPU (red dots), for both a single sample (dashed lines) and 10,000 samples (solid lines). b Corresponding energy to solution, directly measured for the GPU and estimated for the SPU.
