NVIDIA B300 SXM6 AC vs NVIDIA Switch 2 GPU Comparison

Head-to-Head Benchmarks

The recorded data shows a single benchmark result for the NVIDIA B300 SXM6 AC in Geekbench OpenCL, scoring 369,831 points. The NVIDIA Switch 2 GPU has no recorded benchmark results in the database, so direct comparison of measured scores is limited. However, the B300 SXM6 AC occupies the 100th percentile among all GPUs, indicating it outperforms every other recorded device. The nearest rival to the B300 SXM6 AC is the NVIDIA B200, which averages 345,482 points, a 7% deficit. The NVIDIA H200 NVL follows at 334,891 points, 10.4% behind. The AMD Instinct MI300X records 317,994 points, 16.3% lower, and the NVIDIA L40S sits at 295,763 points, 25% behind. These deltas show the B300 SXM6 AC delivers a substantial lead over each competitor, with the gap widening as you move down the list.

The Switch 2 GPU, with no benchmark scores, cannot be placed in a numeric ranking. Its percentile rank of 50 places it at the median of all GPUs in the database, but this is based on absence of data, not measured performance. The B300 SXM6 AC, by contrast, has a verified average benchmark score of 369,831, which is the sole metric used for its ranking. The lack of Switch 2 data means the head-to-head comparison rests entirely on the B300 SXM6 AC's recorded win, though the difference in scores, were the Switch 2 tested, would likely be enormous given the gap between a 1100 W server module and a 40 W console GPU. The database confirms the B300 SXM6 AC wins the only measurable benchmark, but the Switch 2 GPU's absence from the benchmark suite leaves its relative position undefined.
