NVIDIA B200 SXM6 vs NVIDIA GB10 Comparison

The NVIDIA B200 SXM6 and the NVIDIA GB10 serve fundamentally different positions in the server Blackwell lineup. The B200 SXM6 is a massive, high-power accelerator module designed for maximum compute throughput, while the GB10 is a compact, low-power integrated GPU. Benchmark data for the B200 SXM6 is not recorded in the database, whereas the GB10 has two recorded Geekbench scores. This analysis relies on the recorded specifications and available benchmark results to delineate their roles.

Where Each One Wins

The B200 SXM6 wins in raw compute throughput and memory bandwidth. Its FP32 and FP16 performance are both recorded at 69.34 TFLOPS, which is more than double the GB10's 29.71 TFLOPS for both precision formats. The memory subsystem further separates them: the B200 SXM6 offers 180 GB of HBM3e memory with 8.19 TB/s of bandwidth, while the GB10 uses 128 GB of LPDDR5X with 273.2 GB/s. In any workload that saturates memory bandwidth, such as large model training or inference with massive batch sizes, the B200 SXM6 holds a decisive advantage.

The GB10 wins in efficiency, compactness, and practical deployability. Its power draw is recorded at 140 W, compared to the B200 SXM6's 1000 W. The GB10's suggested PSU is 300 W, while the B200 SXM6 requires a 1400 W PSU. The GB10 is an IGP (integrated graphics processor) with dimensions of 150 mm by 51 mm by 150 mm, whereas the B200 SXM6 is an SXM Module with no recorded dimensions. The GB10 also has a display output (1x HDMI), while the B200 SXM6 has no display outputs. For edge deployments, developer kits, or any system where space and power are constrained, the GB10 is the functional choice.

In terms of benchmark presence, the GB10 has verifiable scores: 120,137 in Geekbench OpenCL and 114,648 in Geekbench Vulkan, averaging 117,393. The B200 SXM6 has no recorded benchmark scores. The GB10's percentile rank versus all GPUs is 95, while the B200 SXM6 sits at 50. This indicates that the GB10's measured performance places it in the top 5 percent of all GPUs in the database, while the B200 SXM6 has no data to confirm its standing.

Architecture Differences

Both chips use a 5 nm process node from TSMC. The B200 SXM6 is based on the Blackwell architecture with the GB100 chip, while the GB10 uses Blackwell 2.0 with the GB20B chip. The B200 SXM6 has a die size of 1628 mm² and contains 208,000 million transistors, resulting in a transistor density of 127.8 million per mm². The GB10 has a die size of 382 mm², with its transistor count listed as unknown and no density figure recorded. The B200 SXM6's die is more than four times larger than the GB10's, consistent with its much higher transistor budget.

Core configurations differ substantially. The B200 SXM6 has 18,944 shading units, 592 TMUs, and 24 ROPs, with 592 tensor cores. The GB10 has 6,144 shading units, 384 TMUs, and 48 ROPs, with 48 ray tracing cores and 384 tensor cores. The B200 SXM6 has no recorded RT cores, while the GB10 explicitly includes them. The B200 SXM6 has more shading units, more TMUs, and more tensor cores, but the GB10 has double the ROP count (48 vs 24).

Clock speeds favor the GB10. The B200 SXM6 runs at a base clock of 120 MHz and a boost clock of 1830 MHz. The GB10 runs at a base clock of 1665 MHz and a boost clock of 2418 MHz. The GB10's base clock is nearly 14 times higher than the B200 SXM6's base clock, and its boost clock is about 32 percent higher. This explains how the GB10 achieves a pixel rate of 116.1 GPixel/s, which is higher than the B200 SXM6's 43.92 GPixel/s, despite having fewer shading units. The texture rates tell a different story: the B200 SXM6 records 1,083.4 GTexel/s versus the GB10's 928.5 GTexel/s.

Memory architecture is entirely different. The B200 SXM6 uses HBM3e with a bus width of 8192 bit and memory clock of 2000 MHz (8 Gbps effective). The GB10 uses LPDDR5X with a 256 bit bus and memory clock of 1067 MHz (8.5 Gbps effective). The B200 SXM6's 8192 bit bus is 32 times wider than the GB10's 256 bit bus, which is the primary driver of its 8.19 TB/s bandwidth versus the GB10's 273.2 GB/s.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the B200 SXM6 and GB10. The only recorded benchmark scores belong to the GB10: 120,137 in Geekbench OpenCL and 114,648 in Geekbench Vulkan. These scores produce an average benchmark score of 117,393. The B200 SXM6 has no benchmark data, so no direct performance comparison can be made from measured results.

The GB10's nearest rivals in the database provide context for its performance. The NVIDIA RTX 4000 SFF Ada Generation has an average score of 117,088, which is 0.3 percent lower than the GB10. The AMD Radeon PRO W7700 scores 118,976, which is 1.3 percent higher than the GB10. The NVIDIA Tesla V100 SXM2 16 GB scores 114,395, putting it 2.6 percent behind the GB10. The NVIDIA RTX A5500 Mobile scores 113,944, which is 3 percent behind. This indicates the GB10 performs in the same class as professional workstation and mobile GPUs, slightly outperforming the RTX 4000 SFF Ada Generation, Tesla V100 SXM2, and RTX A5500 Mobile, while trailing the Radeon PRO W7700 by a small margin.

The B200 SXM6's theoretical FP32 output of 69.34 TFLOPS versus the GB10's 29.71 TFLOPS suggests the B200 SXM6 would outperform the GB10 in compute-heavy tasks by a wide margin, but this is not verified by any recorded benchmark score. Similarly, the B200 SXM6's 8.19 TB/s memory bandwidth versus the GB10's 273.2 GB/s indicates a 30-fold advantage in memory throughput, but again, no measured benchmark confirms this in practice.

The Verdict

The recorded data presents a clear division of purpose. The B200 SXM6 is built for maximum compute density: 18,944 shading units, 592 tensor cores, 180 GB of HBM3e, and 8.19 TB/s of memory bandwidth. Its 1000 W TDP and SXM Module form factor indicate a data center accelerator designed for servers with dedicated power and cooling infrastructure. Users who need the highest possible FP32 or FP16 throughput, or who need to fit very large models in GPU memory, should select the B200 SXM6. Its 208,000 million transistors on a 1628 mm² die provide the hardware resources for such workloads.

The GB10 is built for efficiency and integration. Its 140 W TDP, 300 W suggested PSU, and compact IGP form factor make it suitable for systems where power draw and physical space are limiting factors. Its 95th percentile rank among all GPUs, based on its Geekbench scores, shows it delivers competitive performance relative to professional GPUs like the RTX 4000 SFF Ada Generation and Tesla V100 SXM2. Users who need a GPU with display output, lower power consumption, and a smaller footprint should select the GB10.

The B200 SXM6 has no recorded benchmarks, so its real-world performance cannot be verified against the GB10's measured scores. The specification sheet favors the B200 SXM6 in compute throughput, but the GB10 is the only one of the two with confirmed benchmark results. The choice depends on whether the workload prioritizes raw compute and memory capacity (B200 SXM6) or power efficiency, compactness, and verified performance (GB10).
