AMD Radeon PRO W7900 vs NVIDIA H200 NVL Comparison

# Where Each One Wins

The NVIDIA H200 NVL and AMD Radeon PRO W7900 serve fundamentally different roles, and the benchmark data reflects that split clearly. The H200 NVL is a compute-first accelerator with no display outputs, while the W7900 is a workstation graphics card with full video output support. In the single recorded head-to-head benchmark, OpenCL compute, the H200 NVL wins decisively with a score of 334,891 against the W7900's 84,379, a 296.9% advantage. That gap is the defining feature of this comparison.

The H200 NVL takes the compute crown without qualification. Its OpenCL result places it in the 100th percentile of all GPUs in the database, meaning no recorded GPU scores higher. The nearest rival, the NVIDIA B300 SXM6 AC, sits 9.4% ahead, but among the listed peers, the H200 NVL beats the B200 by 3.1%, the AMD Instinct MI300X by 5.3%, and the NVIDIA L40S by 13.2%. For workloads measured by OpenCL, the H200 NVL is at the absolute top of the recorded distribution.

The W7900 wins in areas the OpenCL test does not capture. It has 96 ray tracing cores, while the H200 NVL lists none. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the H200 NVL reports N/A for all three APIs. It provides three DisplayPort 2.1 outputs and one mini-DisplayPort 2.1, while the H200 NVL has no outputs at all. In any application requiring graphics output, real-time rendering, or ray tracing, the W7900 is the only functional choice between the two.

The H200 NVL also leads in memory capacity and bandwidth. Its 141 GB of HBM3e memory on a 6144-bit bus delivers 4.89 TB/s, compared to the W7900's 48 GB of GDDR6 on a 384-bit bus at 864.0 GB/s. The W7900 counters with higher pixel throughput: 479.0 GPixel/s versus 42.84 GPixel/s, a difference that reflects its rasterization-oriented design. Texture rates are close, with the W7900 at 958.1 GTexel/s and the H200 NVL at 942.5 GTexel/s.

Architecture Differences

The two GPUs come from different design philosophies. The H200 NVL uses the GH100 chip on the Hopper architecture, built for server deployments. The W7900 uses the Navi 31 chip on RDNA 3.0, with the codename Plum Bonito, built for professional workstations. Both are fabricated by TSMC on a 5 nm process, but the transistor counts diverge sharply. The H200 NVL packs 80,000 million transistors on an 814 mm² die, while the W7900 contains 57,700 million transistors on a 529 mm² die. Transistor density favors the W7900 at 109.1M per mm² versus 98.3M per mm² for the H200 NVL.

Compute resources follow the server versus workstation split. The H200 NVL has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores, with no ray tracing cores listed. The W7900 has 6,144 shading units, 384 TMUs, 192 ROPs, and 96 ray tracing cores, with no tensor cores listed. The H200 NVL's tensor core count is the largest single compute resource difference, and it explains the OpenCL dominance.

Memory architecture reinforces the divide. The H200 NVL uses HBM3e, a high-bandwidth stacked memory design, while the W7900 uses GDDR6, a conventional graphics memory. Clock speeds also differ in character. The H200 NVL runs at a 1365 MHz base and 1785 MHz boost, with memory at 1593 MHz or 6.4 Gbps effective. The W7900 runs at 1760 MHz base and 2495 MHz boost, with memory at 2250 MHz or 18 Gbps effective. The W7900's higher clocks suit bursty graphics workloads, while the H200 NVL's massive memory bus suits sustained data movement.

Power and physical design differ as well. The H200 NVL draws 600 W, requires an 8-pin EPS connector, and suggests a 1000 W power supply. It is dual-slot and measures 267 mm by 111 mm. The W7900 draws 295 W, uses two 8-pin connectors, and suggests a 600 W power supply. It is triple-slot and measures 280 mm by 110 mm by 51 mm. The W7900 is longer and thicker but consumes roughly half the power.

Head-to-Head Benchmarks

The database contains one direct comparison: Geekbench OpenCL. The H200 NVL scores 334,891, and the W7900 scores 84,379. The delta is 296.9% in favor of the H200 NVL. This is not a marginal win or a narrow edge; it is a near fourfold difference in raw compute throughput as measured by OpenCL.

Context from the nearest rivals clarifies the magnitude. The H200 NVL's score beats the AMD Instinct MI300X, itself a server accelerator, by 5.3%. It beats the NVIDIA L40S, a workstation-oriented GPU, by 13.2%. The only listed GPUs ahead of it are the NVIDIA B200 at 3.1% higher and the B300 SXM6 AC at 9.4% higher. The W7900's 84,379 OpenCL score sits far below that cluster. Its nearest rivals in the database are workstation and older server parts: the NVIDIA Tesla V100 SXM2 16 GB is 3.2% ahead, the NVIDIA RTX A5500 Mobile is 2.8% ahead, the AMD Radeon Pro W6600X is 3.2% behind, and the AMD Radeon Pro Vega II is 1% behind.

The W7900 also has a Geekbench Vulkan score of 137,070, which the H200 NVL does not have recorded, since it reports Vulkan as N/A. That Vulkan result is higher than the W7900's OpenCL score by 62.5%, suggesting the W7900 performs better in graphics-oriented APIs than in pure compute. The H200 NVL has no comparable graphics API result.

The 100th percentile ranking for the H200 NVL in the database means no recorded GPU achieves a higher average benchmark score. The W7900 sits at the 94th percentile, which is strong for a workstation card but clearly below the top of the distribution. The average benchmark score for the H200 NVL is 334,891, while the W7900's average is 110,725, reflecting the one OpenCL result versus the two results recorded for the W7900.

The Verdict

The data points to a clear conclusion: these are different tools for different jobs. The NVIDIA H200 NVL is the compute leader, with a 296.9% OpenCL advantage over the W7900, a 100th percentile ranking, and nearest rivals that are all server-class accelerators. Its 141 GB of HBM3e memory and 4.89 TB/s bandwidth make it suited for large-scale compute workloads, and its 528 tensor cores provide dedicated hardware for AI-style operations. The absence of display outputs and graphics API support means it is not a workstation card in any conventional sense.

The AMD Radeon PRO W7900 is the graphics-capable option. It has display outputs, full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, and 96 ray tracing cores. Its 479.0 GPixel/s pixel rate is over ten times higher than the H200 NVL's 42.84 GPixel/s. It consumes less power at 295 W versus 600 W, occupies a similar footprint, and uses PCIe 4.0 rather than PCIe 5.0.

For a buyer choosing between these two, the decision rests on the workload. If the task is OpenCL compute, large memory allocations, or tensor-heavy processing, the H200 NVL is the only sensible pick, and its 100th percentile ranking supports that. If the task requires rendering, display output, or graphics API compatibility, the W7900 is the only functional option, since the H200 NVL cannot output video or run graphics APIs at all. The H200 NVL wins the compute comparison outright, and the W7900 wins the graphics comparison by default.
