NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 4070 Comparison

NVIDIA's B200 SXM6 and GeForce RTX 4070 occupy opposite ends of the hardware spectrum. The B200 SXM6 is a server-grade Blackwell accelerator with a launch MSRP of 34,999 USD, while the RTX 4070 is an end-of-life consumer Ada Lovelace card with a launch MSRP of 599 USD. The database shows no head-to-head benchmark results for these two, as they are not designed for the same workloads. The B200 SXM6 has no recorded benchmark scores and a percentile rank of 50 among all GPUs. The RTX 4070, in contrast, has an average benchmark score of 37,648 and sits in the 81st percentile.

Head-to-Head Benchmarks

The database does not contain any direct benchmark comparisons between the B200 SXM6 and the RTX 4070. The head-to-head results are empty, and neither product records a win in a shared test. This absence reflects their fundamentally different target markets. The B200 SXM6 is a compute accelerator without display outputs, while the RTX 4070 is a graphics card with full display support. The B200 SXM6's benchmark array is empty, meaning no performance scores have been recorded for it in the database. The RTX 4070, however, has ten recorded benchmark results. In Passmark's G3D test, the RTX 4070 scores 26,927. Its Geekbench OpenCL score is 154,858, and its Geekbench Vulkan score is 174,152. The RTX 4070's Passmark GPU Compute score is 14,720. These scores place it 0.1% ahead of the NVIDIA Tesla P4 (average score 37,628) and 0.4% ahead of the AMD Radeon RX Vega 56 (average score 37,507). The RTX 4070 trails the NVIDIA GeForce RTX 4080 Mobile by 1.3% (average score 38,135) and leads the AMD Radeon PRO W6400 by 1.3% (average score 37,157). Without a single overlapping benchmark, the data cannot establish a direct performance hierarchy between the B200 SXM6 and the RTX 4070.
