NVIDIA B200 vs NVIDIA GeForce RTX 3090 Ti Comparison

NVIDIA B200 and NVIDIA GeForce RTX 3090 Ti occupy opposite ends of the GPU spectrum. The B200 is a server-grade compute accelerator built for massive parallel workloads, while the RTX 3090 Ti is a consumer flagship designed for rendering and high-end gaming. The recorded data shows a single head-to-head benchmark, Geekbench OpenCL, where the B200 delivers a score of 345,482 against the RTX 3090 Ti's 174,441, a 98.1% advantage. This gap, combined with architectural differences spanning three generations, defines a clear separation in intended use cases and performance capabilities.

Where Each One Wins

The NVIDIA B200 wins decisively in raw compute throughput and memory bandwidth, making it the choice for workloads that scale with massive parallelism. Its Geekbench OpenCL score of 345,482 places it in the 100th percentile of all GPUs in the database, meaning it outperforms every other recorded device. The B200's nearest rivals include the NVIDIA H200 NVL (334,891, 3.2% lower), the NVIDIA B300 SXM6 AC (369,831, 6.6% higher), the AMD Instinct MI300X (317,994, 8.6% lower), and the NVIDIA L40S (295,763, 16.8% lower). This places the B200 at the top of its class, with only the B300 SXM6 AC surpassing it among close competitors.

The RTX 3090 Ti, by contrast, wins in areas the B200 does not address at all. It features 24 GB of GDDR6X memory, display outputs (1x HDMI 2.1, 3x DisplayPort 1.4a), and API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The B200 has no display outputs and no recorded DirectX, OpenGL, or Vulkan support. The RTX 3090 Ti also carries 84 dedicated ray tracing cores, a feature entirely absent from the B200's specifications. For any workload requiring visual output, ray tracing, or consumer graphics APIs, the RTX 3090 Ti is the only functional choice.

The benchmark data reflects this split. The B200's single recorded score is 345,482 in Geekbench OpenCL, a compute-oriented test. The RTX 3090 Ti scores 174,441 in the same test, but also records 5741 in 3DMark Steel Nomad DX12 and 215,633 in Geekbench Vulkan, tests that involve graphics and modern rendering pipelines. The B200 has no scores in those categories, reinforcing that its design targets compute density rather than graphics output.

Architecture Differences

The B200 uses the GB100 chip on a 5 nm process from TSMC, packing 104,000 million transistors. The RTX 3090 Ti uses the GA102 chip on an 8 nm process from Samsung, containing 28,300 million transistors on a 628 mm² die. This process and transistor count difference explains the B200's enormous compute capacity: 18,944 shading units, 592 TMUs, and 592 tensor cores, against the RTX 3090 Ti's 10,752 shading units, 336 TMUs, and 336 tensor cores. The B200 also has 24 ROPs, while the RTX 3090 Ti has 112 ROPs, an inversion that reflects the B200's focus on throughput over pixel output.

Memory architecture diverges sharply. The B200 features 90 GB of HBM3e on a 4096-bit bus, delivering 4.10 TB/s bandwidth. The RTX 3090 Ti uses 24 GB of GDDR6X on a 384-bit bus, providing 1.01 TB/s. The B200 has over four times the memory capacity and bandwidth, which is critical for large model inference and data-intensive workloads. Clock speeds tell a complementary story: the B200 runs at a 700 MHz base and 1965 MHz boost, while the RTX 3090 Ti runs at 1560 MHz base and 1860 MHz boost. Despite lower clocks, the B200's wider architecture yields far higher throughput.

FP32 and FP16 performance highlight the compute divide. The B200 delivers 74.45 TFLOPS FP32 and 1,191.2 TFLOPS FP16 (16:1 ratio). The RTX 3090 Ti delivers 40.00 TFLOPS FP32 and 40.00 TFLOPS FP16 (1:1 ratio). The B200's FP16 advantage is nearly 30-fold, a result of its tensor core design optimized for AI training and inference. The RTX 3090 Ti's 1:1 FP16 ratio suggests a general-purpose design balancing graphics and compute, whereas the B200 sacrifices FP32 proportionality for massive tensor throughput.

Power and physical design reinforce the divergence. The B200 is a 1000 W SXM module requiring a 1400 W power supply, with no display outputs and PCIe 5.0 x16 interface. The RTX 3090 Ti is a triple-slot card at 450 W TDP, requiring an 850 W power supply, with a 16-pin power connector, PCIe 4.0 x16, and dimensions of 336 mm length, 140 mm height, and 61 mm width. The B200 is a data-center module; the RTX 3090 Ti is a consumer expansion card.

Head-to-Head Benchmarks

The only common benchmark recorded is Geekbench OpenCL. The B200 scores 345,482 against the RTX 3090 Ti's 174,441, a 98.1% improvement. This is the largest single-metric gap in the comparison, and it aligns with the B200's 100th percentile ranking versus the RTX 3090 Ti's 95th percentile. In absolute terms, the B200 nearly doubles the RTX 3090 Ti's OpenCL compute score.

Interpreting this score through the nearest rivals adds context. The B200's 345,482 is 3.2% above the H200 NVL (334,891) and 8.6% above the AMD Instinct MI300X (317,994). It sits 16.8% above the L40S (295,763). The RTX 3090 Ti's 174,441 is within 0.7% of the NVIDIA L4 (131,072) and 2.4% below the RTX 4000 Ada Generation (135,218) and A10M (135,230), with the AMD Radeon PRO W6800 (135,396) also 2.6% above. The RTX 3090 Ti's closest rivals are workstation cards with similar average scores, while the B200 competes against top-tier accelerators.

The RTX 3090 Ti's other recorded scores, 5741 in 3DMark Steel Nomad DX12 and 215,633 in Geekbench Vulkan, have no B200 counterpart. These results indicate the RTX 3090 Ti's strength in graphics APIs, but the absence of B200 data prevents direct comparison. The database records only one head-to-head test, and the B200 wins it outright. The RTX 3090 Ti wins no benchmark in this pairing because the only shared test is OpenCL.

The Verdict

The data points to a straightforward selection rule. Choose the NVIDIA B200 if the workload is pure compute, especially AI, machine learning, or large-scale data processing. Its Geekbench OpenCL score of 345,482 is 98.1% above the RTX 3090 Ti's 174,441, and its 100th percentile ranking confirms it as the top performer in the database. The B200's 90 GB HBM3e memory with 4.10 TB/s bandwidth and 1,191.2 TFLOPS FP16 performance make it suitable for tasks that saturate memory and tensor cores. Its 1000 W TDP and SXM form factor indicate a server environment with dedicated power and cooling.

Choose the NVIDIA GeForce RTX 3090 Ti if the workload involves graphics, rendering, or any visual output. It is the only one of the two with display outputs and API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 84 ray tracing cores and 112 ROPs support real-time graphics workloads that the B200 cannot handle. The RTX 3090 Ti's 40.00 TFLOPS FP32 and 40.00 TFLOPS FP16 performance, while far below the B200 in compute, is still substantial for a consumer card, and its 24 GB GDDR6X memory with 1.01 TB/s bandwidth is sufficient for high-resolution rendering. Its 450 W TDP and triple-slot design fit into a standard workstation or desktop system, unlike the B200's 1400 W PSU requirement.

The benchmark results confirm the verdict: the B200 wins the only shared test, but the RTX 3090 Ti remains the sole option for graphics tasks. The two GPUs are not competitors; they are complementary tools for different domains. The B200 is for compute density, the RTX 3090 Ti is for graphics output. The database shows no scenario where they overlap in function.
