NVIDIA B200 SXM6 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Where Each One Wins

The benchmark data splits these two NVIDIA Blackwell offerings into entirely different use cases. The NVIDIA B200 SXM6 is a server accelerator with no display outputs, no graphics API support, and no recorded benchmark scores in the database. Its strengths are structural: 180 GB of HBM3e memory, an 8192-bit bus, 8.19 TB/s of memory bandwidth, and 592 tensor cores. This is a compute monster built for massive parallel workloads where memory capacity and bandwidth dictate performance. The RTX PRO 5000 Blackwell, by contrast, posts actual benchmark numbers: 9579.5 in 3DMark Steel Nomad DX12, 254116 in Geekbench OpenCL, and 282631 in Geekbench Vulkan. It sits at the 98th percentile among all GPUs in the database, while the B200 sits at the 50th percentile with an average benchmark score of zero because it has no recorded entries.

The RTX PRO 5000 wins on every measured benchmark because it is the only one with measurements. The B200 wins on raw hardware capability that does not translate to graphics or consumer workloads. The RTX PRO 5000 has 110 RT cores, 160 ROPs, and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The B200 has no RT cores listed, only 24 ROPs, and its API support is marked N/A across the board. For rendering, ray tracing, or any graphics API workload, the RTX PRO 5000 is the only functional choice. For dense compute, memory-bound AI training, or inference at scale, the B200's hardware profile suggests dominance, but the database contains no direct measurements to confirm it.

Architecture Differences

Both chips use TSMC's 5 nm process, but they diverge sharply in scale and design philosophy. The B200 uses the GB100 chip, measures 1628 mm², and packs 208,000 million transistors, yielding a density of 127.8 million transistors per mm². The RTX PRO 5000 uses the GB202 chip, measures 750 mm², and contains 92,200 million transistors, for a density of 122.9 million per mm². The B200 is more than twice the die area and more than twice the transistor count, but the RTX PRO 5000 runs at far higher clocks: 1740 MHz base and 2377 MHz boost versus 120 MHz base and 1830 MHz boost for the B200. That clock gap is enormous, but it reflects different operating environments. The B200 is a 1000 W SXM module designed for server chassis with heavy cooling; the RTX PRO 5000 is a 300 W dual-slot card with a single 16-pin power connector.

Memory architecture separates them completely. The B200 uses HBM3e with 180 GB capacity, an 8192-bit bus, and 8.19 TB/s bandwidth. The RTX PRO 5000 uses GDDR7 with 48 GB capacity, a 384-bit bus, and 1.34 TB/s bandwidth. The B200 has 5.4 times the capacity and 6.1 times the bandwidth. The B200's memory clock is listed at 2000 MHz with 8 Gbps effective, while the RTX PRO 5000 runs at 1750 MHz with 28 Gbps effective. The RTX PRO 5000's faster per-pin memory speed does not compensate for the B200's vastly wider bus.

Shader and texture resources also differ. The B200 has 18,944 shading units, 592 TMUs, and 592 tensor cores. The RTX PRO 5000 has 14,080 shading units, 440 TMUs, and 440 tensor cores. The B200 leads in every count, yet its FP32 throughput of 69.34 TFLOPS barely edges the RTX PRO 5000's 66.94 TFLOPS. The B200's texture rate of 1,083.4 GTexel/s narrowly beats 1,045.9 GTexel/s. Pixel rate tells the opposite story: the RTX PRO 5000 delivers 380.3 GPixel/s versus 43.92 GPixel/s for the B200, an 8.7x advantage driven by the ROP count of 160 versus 24. The B200's compute-oriented design sacrifices rasterization throughput entirely.

Head-to-Head Benchmarks

The database lists no shared benchmark entries for these two cards, so direct score comparisons use the RTX PRO 5000's recorded results and the B200's absent ones. The RTX PRO 5000 scores 9579.5 in 3DMark Steel Nomad DX12, a graphics workload that the B200 cannot run due to its lack of DirectX support. In Geekbench OpenCL, the RTX PRO 5000 scores 254116; its Vulkan score reaches 282631. The B200 has no entries for any of these tests, consistent with its server-only positioning. Its average benchmark score is zero, and its percentile rank among all GPUs is 50, which reflects the absence of data rather than mid-pack performance.

The RTX PRO 5000's nearest rivals provide context. The NVIDIA A100 SXM4 80 GB scores 183725, which is 0.9% above the RTX PRO 5000's average of 182109. The RTX 5000 Ada Generation scores 184664, 1.4% higher. The GeForce RTX 4090 D scores 178050, 2.3% lower. The A100 SXM4 40 GB scores 187147, 2.7% higher. This places the RTX PRO 5000 in a tight cluster with previous-generation server and workstation parts, trading blows within a few percentage points. The B200 has no nearest rivals listed, so no comparable positioning exists.

The FP32 and FP16 figures are nearly identical between the two cards: 69.34 TFLOPS for the B200 versus 66.94 TFLOPS for the RTX PRO 5000 in both precisions, with a 1:1 ratio for FP16. This near parity in raw compute, despite the B200's enormous memory advantage, suggests the B200's value lies in memory capacity and bandwidth rather than raw FLOPs. The RTX PRO 5000 matches the B200 in compute throughput while consuming 300 W instead of 1000 W, a 70% power reduction. The B200's suggested PSU is 1400 W; the RTX PRO 5000's is 700 W.

The Verdict

The data points to a clean split. The RTX PRO 5000 Blackwell is the only one of the two that can render graphics, run DirectX or Vulkan workloads, or drive displays. It has four DisplayPort 2.1b outputs, full API support, and recorded benchmark scores at the 98th percentile. Its 48 GB GDDR7 memory and 1.34 TB/s bandwidth suit workstation tasks where capacity is sufficient and power efficiency matters. The B200 SXM6 is a server compute accelerator with no display outputs and no graphics API support. Its 180 GB HBM3e memory and 8.19 TB/s bandwidth dwarf the RTX PRO 5000, and its 1000 W thermal design power reflects a different operating envelope. The B200's 24 ROPs and 43.92 GPixel/s pixel rate make it useless for rasterization, but its 592 tensor cores and massive memory footprint target AI training and inference.

For a workstation that needs to display results, run CUDA compute, and handle ray tracing, the RTX PRO 5000 is the functional choice. Its 110 RT cores, 160 ROPs, and Vulkan 1.4 support deliver measurable graphics performance. For a server rack where compute density and memory scale outweigh power draw, the B200 offers 3.75 times the memory capacity and 6.1 times the bandwidth. The RTX PRO 5000's launch MSRP is 5,099 USD; the B200's is 34,999 USD. The B200's predecessor is Server Hopper and its successor is Server Rubin, while the RTX PRO 5000's predecessor is Workstation Ada with no successor listed. The B200 released on 2024-10-31, the RTX PRO 5000 on 2025-03-17.
