NVIDIA B200 SXM6 vs NVIDIA RTX 4000 Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the NVIDIA B200 SXM6 and the NVIDIA RTX 4000 Ada Generation. The B200 SXM6 has no recorded benchmark scores, while the RTX 4000 Ada Generation has two recorded entries. This asymmetry means a direct score-for-score comparison is not possible from the recorded data.

The RTX 4000 Ada Generation delivers a Geekbench OpenCL score of 146,593 and a Geekbench Vulkan score of 123,842. Its average benchmark score across all recorded tests is 135,218. This places the card at the 95th percentile among all GPUs in the database.

The B200 SXM6 sits at the 50th percentile with an average benchmark score of zero, reflecting the absence of any recorded benchmark results. The data does not indicate any wins for either product in head-to-head testing, as the head-to-head benchmark array is empty.

The RTX 4000 Ada Generation's nearest rivals in the database provide useful context. The NVIDIA A10M scores 135,230, which is effectively identical with a delta of 0 percent. The AMD Radeon PRO W6800 scores 135,396, placing it 0.1 percent ahead of the RTX 4000 Ada. The AMD Radeon Pro W6800X Duo scores 135,774, or 0.4 percent ahead, and the AMD Radeon PRO V620 scores 136,472, or 0.9 percent ahead. These narrow margins indicate that the RTX 4000 Ada Generation sits in a tightly contested performance cluster among workstation-class accelerators.

The raw specification data reveals stark contrasts between the two products, even without benchmark scores. The B200 SXM6 is built around the GB100 chip with 208,000 million transistors on a 1628 mm² die, while the RTX 4000 Ada Generation uses the AD104 chip with 35,800 million transistors on a 294 mm² die. The B200 SXM6 has 18,944 shading units, 592 TMUs, and 24 ROPs, compared to 6,144 shading units, 192 TMUs, and 64 ROPs on the RTX 4000 Ada. The B200 SXM6 also carries 592 tensor cores, while the RTX 4000 Ada has 192.

Memory configurations differ dramatically. The B200 SXM6 integrates 180 GB of HBM3e on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 4000 Ada Generation uses 20 GB of GDDR6 on a 160-bit bus, delivering 360.0 GB/s. This represents a 22.8 times difference in raw memory bandwidth in favor of the B200 SXM6.

Compute throughput figures reinforce the separation. The B200 SXM6 reaches 69.34 TFLOPS in both FP32 and FP16, while the RTX 4000 Ada Generation reaches 26.73 TFLOPS in both. The B200 SXM6 also leads in texture rate with 1,083.4 GTexel/s versus 417.6 GTexel/s, though the RTX 4000 Ada leads in pixel rate with 139.2 GPixel/s versus 43.92 GPixel/s.

Clock behavior reflects their different design targets. The B200 SXM6 has a 120 MHz base clock and an 1830 MHz boost clock, while the RTX 4000 Ada Generation starts at 1500 MHz base and boosts to 2175 MHz. The B200 SXM6's memory runs at 2000 MHz with 8 Gbps effective throughput, whereas the RTX 4000 Ada's memory runs at 2250 MHz with 18 Gbps effective throughput.

The Verdict

The recorded data supports a clear separation of roles. The RTX 4000 Ada Generation is a workstation graphics card with active benchmark results, a 95th percentile ranking, and confirmed API support. The B200 SXM6 is a server accelerator with no recorded benchmarks, no display outputs, and a 50th percentile ranking.

Users requiring a single-slot, 130 W card with 20 GB of GDDR6 memory and four DisplayPort 1.4a outputs should consider the RTX 4000 Ada Generation. Its 95th percentile standing indicates strong performance relative to all GPUs in the database, and its nearest rivals all fall within 0.9 percent of its average score, confirming a competitive position in its class.

Users requiring maximum memory capacity and bandwidth for large-scale compute workloads should consider the B200 SXM6. The 180 GB HBM3e configuration with 8.19 TB/s bandwidth is an order of magnitude beyond the RTX 4000 Ada's capabilities. The 69.34 TFLOPS FP32 throughput is 2.6 times the RTX 4000 Ada's 26.73 TFLOPS.

The B200 SXM6 uses a PCIe 6.0 x16 interface, while the RTX 4000 Ada Generation uses PCIe 4.0 x16. The B200 SXM6 requires a 1400 W suggested power supply and consumes 1000 W, while the RTX 4000 Ada Generation consumes 130 W with a 300 W suggested power supply. The B200 SXM6 also has no display outputs, making it unsuitable for direct display connectivity.

The RTX 4000 Ada Generation supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists no API support in the recorded data. This makes the RTX 4000 Ada the only one of the two with confirmed graphics API compatibility.
