AMD Radeon PRO W7900D vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the AMD Radeon PRO W7900D and NVIDIA B200 SXM6. Both entries show zero benchmark entries, zero average scores, and zero win counts in their respective columns. Consequently, there is no measured performance delta between these two accelerators in the current dataset. The absence of benchmark data means that any comparative performance assessment must rely entirely on the architectural and specification differences listed in the database rather than empirical test results.

The AMD Radeon PRO W7900D posts a peak FP32 throughput of 52.99 TFLOPS, while the NVIDIA B200 SXM6 records 69.34 TFLOPS in the same precision. That figure places the NVIDIA part roughly 31% higher in raw single-precision compute, a difference derived from the specification sheet rather than a tested workload. In FP16 compute, both cards show identical 1:1 ratios, with the AMD part again at 52.99 TFLOPS and the NVIDIA part at 69.34 TFLOPS, preserving the same proportional gap.

Memory bandwidth presents an even starker contrast. The NVIDIA B200 SXM6 delivers 8.19 TB/s across an 8192-bit bus using HBM3e, while the AMD Radeon PRO W7900D provides 864.0 GB/s over a 384-bit GDDR6 interface. The NVIDIA module’s bandwidth is approximately 9.5 times higher, a factor that heavily favors data-intensive workloads such as large model inference or training. The AMD card’s pixel rate, however, is substantially higher at 414.0 GPixel/s versus 43.92 GPixel/s for the NVIDIA part, reflecting its rasterization-oriented design and 192 ROPs compared to just 24 ROPs on the B200.

Texture rate favors the NVIDIA accelerator, with 1,083.4 GTexel/s against 827.9 GTexel/s on the AMD card, a 31% advantage that aligns with its higher TMU count of 592 versus 384. The AMD part counters with a much higher boost clock of 2156 MHz versus 1830 MHz on the NVIDIA module, though the NVIDIA base clock is drastically lower at 120 MHz compared to 1327 MHz on the AMD card.

Where Each One Wins

The AMD Radeon PRO W7900D wins in rasterization-derived metrics. Its 192 ROPs and 414.0 GPixel/s fill rate indicate a design suited for traditional graphics rendering, display output, and pixel-heavy workloads. It also carries three DisplayPort 2.1 outputs plus a mini-DisplayPort 2.1, making it a functional graphics card for workstation visualization. Its 48 GB GDDR6 memory, while smaller than the NVIDIA part, is paired with a 384-bit bus and operates at 18 Gbps effective, which is adequate for large frame buffers in professional rendering tasks.

The NVIDIA B200 SXM6 wins in raw compute density and memory capacity. Its 180 GB HBM3e pool with 8.19 TB/s bandwidth dwarfs the AMD option, and its 592 tensor cores provide dedicated matrix math acceleration that the AMD card completely lacks, as the database lists no tensor core count for the Radeon part. The NVIDIA module’s 69.34 TFLOPS in both FP32 and FP16, combined with 18944 shading units, makes it the stronger candidate for simulation, AI training, and high-performance computing. The B200 also leads in texture throughput at 1,083.4 GTexel/s, which benefits volume rendering and texture-heavy compute shaders.

The AMD card operates at a 295 W TDP with a suggested 600 W power supply, while the NVIDIA module draws 1000 W and requires a suggested 1400 W PSU. The AMD part is a triple-slot PCIe card with a 280 mm length, whereas the NVIDIA part is an SXM module with no display outputs and no listed dimensions, indicating a server blade or proprietary chassis orientation rather than a standalone graphics card.

Architecture Differences

The AMD Radeon PRO W7900D uses the Navi 31 chip built on the RDNA 3.0 architecture, codenamed Plum Bonito, manufactured on a 5 nm process at TSMC. It contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The NVIDIA B200 SXM6 uses the GB100 chip on the Blackwell architecture, also fabricated on a 5 nm TSMC process, but packs 208,000 million transistors across a 1628 mm² die, for a density of 127.8 million per mm². The NVIDIA die is more than three times larger in area and holds roughly 3.6 times more transistors.

Memory technology diverges sharply. The AMD card uses GDDR6 with a 384-bit bus and 864.0 GB/s bandwidth. The NVIDIA module uses HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The NVIDIA part’s bus width is over 21 times wider, and its memory capacity of 180 GB is 3.75 times the AMD card’s 48 GB. Clock behavior also differs: the AMD part has a 1327 MHz base and 2156 MHz boost, while the NVIDIA module lists a 120 MHz base and 1830 MHz boost. The NVIDIA base clock is unusually low, indicating a power-management design that downclocks aggressively at idle or under partial load.

Compute resources differ in kind as well as quantity. The AMD card has 6144 shading units, 384 TMUs, 192 ROPs, and 96 ray tracing cores, but no tensor cores. The NVIDIA module has 18944 shading units, 592 TMUs, only 24 ROPs, no listed ray tracing cores, and 592 tensor cores. The NVIDIA part supports PCIe 6.0 x16, while the AMD card uses PCIe 4.0 x16. API support is another differentiator: the AMD card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the NVIDIA module lists N/A for all three, confirming its compute-only orientation.

The AMD card has a release date of 2025-09-24 and lists its predecessor as Radeon Pro Vega with no successor. The NVIDIA module was released on 2024-10-31, lists Server Hopper as its predecessor and Server Rubin as its successor, and carries a launch MSRP of 34,999 USD.

The Verdict

The data indicates two fundamentally different products. The AMD Radeon PRO W7900D is a graphics-oriented workstation card with display outputs, rasterization hardware, and a conventional PCIe form factor. Its 414.0 GPixel/s pixel rate, 192 ROPs, and DirectX 12 Ultimate support position it for rendering, visualization, and interactive graphics tasks where pixel throughput and display connectivity matter. Its 48 GB memory and 864.0 GB/s bandwidth are substantial for a workstation card, but they are not in the same class as the NVIDIA module’s memory subsystem.

The NVIDIA B200 SXM6 is a compute accelerator with no display outputs, no graphics API support, and a server-only SXM form factor. Its 180 GB HBM3e memory, 8.19 TB/s bandwidth, 592 tensor cores, and 69.34 TFLOPS FP32 throughput make it the clear choice for AI training, large-scale simulation, and high-performance computing workloads that can utilize its memory capacity and matrix acceleration. The 1000 W TDP and 1400 W suggested PSU reflect its data-center orientation.

Users requiring a graphics card for professional visualization should select the AMD part, as it is the only one with display outputs and graphics API support. Users deploying compute accelerators in server environments should select the NVIDIA module, given its memory bandwidth, tensor core count, and higher raw FP32 performance. The launch MSRP of the NVIDIA B200 SXM6 is 34,999 USD, while the AMD card has no listed launch MSRP.
