NVIDIA B200 SXM6 vs NVIDIA GeForce RTX 5090 D V2 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons between the NVIDIA B200 SXM6 and the NVIDIA GeForce RTX 5090 D V2. The head-to-head benchmark array is empty, and the win counts sit at zero for both parts. This absence of comparative data is itself informative: the two cards occupy different segments, and no shared workload has been logged against both.

The only benchmark score in the entire dataset belongs to the RTX 5090 D V2. It posts 16,504 points in the 3DMark Steel Nomad DX12 test. The B200 SXM6 has no benchmark entries at all, and its average benchmark score is recorded as zero. Its percentile ranking against all GPUs is 50, while the RTX 5090 D V2 sits at the 59th percentile. The percentile gap suggests the consumer card lands higher in the overall distribution, but the B200's zero-score status means that percentile is not derived from measured performance; it is a placeholder for a device that has not been exercised in the benchmark suite.

For the RTX 5090 D V2, the nearest rivals in the database are revealing. The NVIDIA T400 posts an average score of 16,508, which is effectively identical, a delta of 0 percent. The AMD Radeon PRO W7500 scores 16,415, a 0.5 percent deficit. The NVIDIA RTX PRO 6000 Blackwell scores 16,408, a 0.6 percent gap. The AMD Radeon RX 5700 XT scores 16,361, a 0.9 percent shortfall. These deltas are tiny, all within one point of the RTX 5090 D V2's own score. The data shows that in this particular DX12 steel nomad workload, the RTX 5090 D V2 is statistically tied with a low-end professional card and a several-generations-old gaming card. That outcome is curious for a flagship consumer GPU and suggests the workload may not be representative of the card's compute strengths.

The B200 SXM6 has no nearest rivals listed, which further separates it from comparative analysis. Without scores, the database cannot place it relative to any other GPU in a measured sense. The only numerical anchor for the B200 is its hardware configuration, which differs massively from the RTX 5090 D V2. Those differences are covered in the architecture and specification sections below, but the benchmark section must remain honest: no data, no wins, no deltas.

Architecture Differences

The two GPUs share a manufacturer and a 5 nm process node from TSMC, but the similarities end there. The B200 SXM6 uses the GB100 chip, built on the Blackwell architecture and belongs to the Server Blackwell (Bxx) generation. The RTX 5090 D V2 uses the GB202 chip, built on Blackwell 2.0 and belongs to the GeForce 50 series. The architecture naming suggests a refinement for the consumer part, but the underlying node is identical.

Transistor counts and die sizes diverge sharply. The B200 packs 208,000 million transistors onto a 1628 mm² die, yielding a density of 127.8 million transistors per square millimeter. The RTX 5090 D V2 contains 92,200 million transistors on a 750 mm² die, with a density of 122.9 million per square millimeter. The B200 has more than double the transistors and more than double the die area. The density figures are close, which indicates both designs are packed similarly, but the B200's sheer scale is on another level.

Clock behavior differs in an unusual way. The B200 has a base clock of just 120 MHz, which is extraordinarily low, and a boost clock of 1830 MHz. The RTX 5090 D V2 has a base clock of 2017 MHz and a boost of 2407 MHz. The consumer card runs far higher clocks at both points. The B200's low base clock likely reflects a power management strategy for a massive chip, but the boost clock shows it can ramp up substantially under load.

Memory configurations are a major split. The B200 uses 180 GB of HBM3e on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RTX 5090 D V2 uses 24 GB of GDDR7 on a 384-bit bus, delivering 1.34 TB/s. The B200 has 7.5 times the memory capacity and over 6 times the bandwidth. The memory clock numbers are interesting: the B200's memory runs at 2000 MHz with 8 Gbps effective, while the RTX 5090 D V2 runs at 1750 MHz with 28 Gbps effective. The GDDR7 uses a much higher effective data rate per pin, but the HBM3e's enormous bus width overwhelms it in total bandwidth.

Compute resources also differ. The B200 has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The RTX 5090 D V2 has 21,760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The consumer card has more shading units, more TMUs, more ROPs, and more tensor cores. The B200 has no RT cores listed, while the RTX 5090 D V2 has 170. The B200's pixel rate is 43.92 GPixel/s versus 423.6 GPixel/s for the RTX 5090 D V2, a tenfold difference. The texture rates are 1,083.4 GTexel/s versus 1,636.8 GTexel/s. Floating point performance also favors the consumer card: 69.34 TFLOPS FP32 for the B200 versus 104.8 TFLOPS for the RTX 5090 D V2. Both have a 1:1 FP16 ratio.

The API support is another divider. The B200 lists DirectX, OpenGL, and Vulkan all as N/A. The RTX 5090 D V2 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 is a compute-focused server part with no graphics API support, while the consumer card is fully equipped for gaming and graphics workloads.

Where Each One Wins

The data points to distinct domains. The RTX 5090 D V2 wins on raw compute throughput metrics: higher FP32, higher texture rate, higher pixel rate, more shading units, more TMUs, more ROPs, more tensor cores, and the only RT cores. It also has full graphics API support, display outputs, and a much lower TDP of 575 W versus 1000 W. For any workload that runs on standard graphics APIs or requires display output, the RTX 5090 D V2 is the only functional choice between the two.

The B200 SXM6 wins on memory capacity and bandwidth by a wide margin. Its 180 GB of HBM3e and 8.19 TB/s bandwidth dwarf the RTX 5090 D V2's 24 GB and 1.34 TB/s. For large models or datasets that exceed 24 GB, the B200 is the only option that can hold the data on-chip. The B200 also has a newer PCIe interface, PCIe 6.0 x16 versus PCIe 5.0 x16, which matters for host communication in server environments. The B200's transistor count of 208,000 million and die size of 1628 mm² indicate a design aimed at massive parallel throughput, even if its clock speeds are lower.

The benchmark situation favors the RTX 5090 D V2 by default, since it has a measured score of 16,504 in 3DMark Steel Nomad DX12 and a 59th percentile ranking. The B200 has no scores and sits at the 50th percentile placeholder. That said, the Steel Nomad test is a DX12 graphics workload, and the B200 has no DirectX support, so the test would not apply to it in any meaningful way. The absence of a score for the B200 is not evidence of poor performance; it is evidence that the test suite does not cover server compute parts.

The nearest rival data for the RTX 5090 D V2 shows it clustered with the NVIDIA T400, AMD Radeon PRO W7500, NVIDIA RTX PRO 6000 Blackwell, and AMD Radeon RX 5700 XT, all within 0.9 percent. That cluster suggests the RTX 5090 D V2's measured performance in this specific workload is not exceptional relative to lower-tier cards, which is a notable finding for a flagship consumer GPU. The B200 has no comparable data.

The Verdict

The recorded data supports a clear split. The NVIDIA GeForce RTX 5090 D V2 is the choice for graphics-intensive tasks, consumer-facing workloads, and any scenario requiring modern API support. It delivers 104.8 TFLOPS FP32, 423.6 GPixel/s pixel rate, 1,636.8 GTexel/s texture rate, 170 RT cores, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. It has display outputs, a dual-slot form factor, and a TDP of 575 W. Its benchmark score of 16,504 in 3DMark Steel Nomad DX12 places it at the 59th percentile, and its nearest rivals are all within 0.9 percent, indicating solid but not dominant performance in that test.

The NVIDIA B200 SXM6 is the choice for memory-bound server workloads. Its 180 GB of HBM3e and 8.19 TB/s bandwidth are the standout figures. No consumer GPU in this comparison comes close. The B200 also has PCIe 6.0 support, a 1000 W TDP, and a 1400 W suggested PSU, all pointing to a rack-mounted, high-throughput compute role. Its lack of display outputs and N/A API support confirm it is not a graphics card in the traditional sense.

The release timeline also informs the verdict. The B200 launched on 2024-10-31 as a server part in the Blackwell generation, with a successor already named as Server Rubin. The RTX 5090 D V2 launched on 2025-08-14 in the GeForce 50 series, with a successor named as GeForce 60. Both are active production parts.

The launch MSRP difference is stark: 34,999 USD for the B200 versus 2,299 USD for the RTX 5090 D V2. That price gap aligns with their intended markets, but the data does not support any claims about value or cost-effectiveness. The B200 targets data center deployments where capacity and bandwidth justify its cost. The RTX 5090 D V2 targets desktop users who need graphics performance, API compatibility, and display connectivity.

In sum, the data indicates the RTX 5090 D V2 wins on every compute throughput metric and every graphics feature. The B200 SXM6 wins on memory capacity, memory bandwidth, and bus interface generation. A user with graphics workloads should pick the RTX 5090 D V2. A user with massive memory-resident datasets should pick the B200 SXM6. The two do not compete in the same arena, and the benchmark data reflects that separation through the absence of shared tests and the B200's zero-score status.
