NVIDIA B200 vs NVIDIA GeForce RTX 5090 D Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark between these two GPUs is Geekbench OpenCL, and the results are decisive. The NVIDIA B200 scores 345,482, while the NVIDIA GeForce RTX 5090 D scores 310,674. That gives the B200 an 11.2% lead in raw compute throughput as measured by this workload. The B200 wins the only head-to-head contest recorded in the database, with a 1-0 record over the RTX 5090 D.

Context from the nearest rivals puts these numbers in perspective. The B200 sits at the 100th percentile of all GPUs in the database, meaning no other recorded part scores higher on average. Its closest competitor is the NVIDIA B300 SXM6 AC at 369,831, which is 6.6% faster, but the B200 still beats the NVIDIA H200 NVL (334,891) by 3.2%, the AMD Instinct MI300X (317,994) by 8.6%, and the NVIDIA L40S (295,763) by 16.8%. The RTX 5090 D, by contrast, sits at the 92nd percentile, with its average benchmark score of 77,712 heavily influenced by a wide range of tests beyond OpenCL. It is nearly tied with the AMD Radeon RX 6650M XT (76,904, just 1.1% behind) and slightly behind the AMD Radeon RX 6850M XT (78,940, 1.6% faster) and the NVIDIA Tesla P100 PCIe 12 GB (79,396, 2.1% faster).

That comparison is worth noting: the RTX 5090 D's composite average is dragged down by its DirectX and 2D results, while its Geekbench OpenCL score is far more competitive. In OpenCL specifically, the RTX 5090 D trails the B200 by just 11.2%, which is a smaller gap than the B200's margin over the H200 NVL. The B200 is clearly the stronger compute part, but the RTX 5090 D is not far off in this particular test, despite being a consumer-oriented product.

Architecture Differences

The two GPUs share the Blackwell architecture family but diverge in implementation. The B200 uses the GB100 chip and is designated as Server Blackwell (Bxx) generation, while the RTX 5090 D uses the GB202 chip and is part of the GeForce 50 generation, listed as Blackwell 2.0. Both are built on a 5 nm process at TSMC, but the similarities end there.

Transistor counts differ significantly. The B200 packs 104,000 million transistors, while the RTX 5090 D has 92,200 million. The RTX 5090 D has a published die size of 750 mm² and a transistor density of 122.9M per mm²; the B200's die size and density are not recorded. This suggests the B200's larger transistor budget is spread across a different physical layout, likely due to its server-focused design.

Memory architecture is a major differentiator. The B200 uses 90 GB of HBM3e on a 4096-bit bus, delivering 4.10 TB/s of bandwidth. The RTX 5090 D uses 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s. The B200 has more than double the memory bandwidth and nearly three times the capacity, which is typical for a compute accelerator handling large models and datasets. The RTX 5090 D's GDDR7 memory runs at 28 Gbps effective, while the B200's HBM3e runs at 8 Gbps effective, but the B200's much wider bus compensates with far higher aggregate throughput.

Compute resources also differ in structure. The B200 has 18,944 shading units, 592 TMUs, and only 24 ROPs, with 592 tensor cores. The RTX 5090 D has 21,760 shading units, 680 TMUs, 176 ROPs, and 170 RT cores, with 680 tensor cores. The RTX 5090 D has more shading units and more texture units, but the B200's low ROP count (24 versus 176) reflects its focus on compute rather than rasterization. The RTX 5090 D includes dedicated RT cores, which the B200 does not list, indicating a clear separation between AI/data-center workloads and graphics rendering.

Clock speeds reinforce this split. The B200 runs at a 700 MHz base and 1965 MHz boost, while the RTX 5090 D runs at 2017 MHz base and 2407 MHz boost. The RTX 5090 D's higher clocks help it reach 104.8 TFLOPS FP32, versus the B200's 74.45 TFLOPS FP32. In FP16, the gap reverses dramatically: the B200 delivers 1,191.2 TFLOPS (16:1 ratio), while the RTX 5090 D delivers 104.8 TFLOPS (1:1 ratio). That 16:1 FP16 throughput on the B200 is the clearest indicator of its AI-acceleration purpose.

Power and physical design differ as expected. The B200 has a 1000 W TDP and requires a 1400 W suggested PSU, mounted as an SXM Module with no display outputs. The RTX 5090 D has a 575 W TDP, a 950 W suggested PSU, is dual-slot with a 16-pin power connector, and measures 304 mm by 137 mm by 48 mm. The B200 is a data-center module; the RTX 5090 D is a physical graphics card with display outputs (1x HDMI 2.1b and 3x DisplayPort 2.1b) and full API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 lists no API support, reinforcing its non-rendering role.

The Verdict

The data paints a clear picture of two GPUs built for different purposes. The B200 is a server accelerator with a 100th percentile ranking, a 3.2% lead over the H200 NVL, an 8.6% lead over the AMD Instinct MI300X, and a 16.8% lead over the L40S. Its 90 GB HBM3e memory, 4.10 TB/s bandwidth, and 1,191.2 TFLOPS FP16 throughput make it the stronger choice for large-scale compute and AI workloads. Its 1000 W TDP and SXM Module form factor are not suited to desktop use, and it has no display outputs or graphics API support.

The RTX 5090 D, on the other hand, is a GeForce 50-series graphics card with a 92nd percentile ranking, full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, 170 RT cores, and display outputs. It has higher FP32 performance (104.8 TFLOPS versus 74.45 TFLOPS), higher pixel rate (423.6 GPixel/s versus 47.16 GPixel/s), and higher texture rate (1,636.8 GTexel/s versus 1,163.3 GTexel/s). It also has more shading units (21,760 versus 18,944) and more tensor cores (680 versus 592). Its 32 GB GDDR7 memory and 1.79 TB/s bandwidth are far below the B200, but they are paired with a 575 W TDP and a 950 W suggested PSU, making it a practical card for a desktop workstation.

The verdict follows the architecture. Pick the B200 if the workload is pure compute, especially FP16-heavy AI tasks, where it has a 16:1 throughput advantage and over twice the memory bandwidth. Pick the RTX 5090 D if the workload involves graphics rendering, rasterization, or ray tracing, where its RT cores, higher clocks, higher FP32, and API support are decisive. In the single shared benchmark, the B200 wins by 11.2%, but that test does not exercise the RTX 5090 D's rendering capabilities. The recorded data supports both parts as leaders in their respective domains, with the B200 as the absolute top-ranked GPU in the database and the RTX 5090 D as a strong, well-rounded consumer card.
