AMD Radeon PRO W7700 vs NVIDIA H20 NVL16 Comparison

AMD Radeon PRO W7700 vs NVIDIA H20 NVL16 presents a stark contrast between a workstation visualization card and a server compute accelerator. The data shows two devices designed for entirely different workloads, with the AMD card delivering 108245 in Geekbench OpenCL and 129706 in Geekbench Vulkan, while the NVIDIA H20 NVL16 has no recorded benchmark scores in the database. The Radeon PRO W7700 sits at the 95th percentile among all GPUs, whereas the H20 NVL16 sits at the 50th percentile with an average benchmark score of zero.

Where Each One Wins

The AMD Radeon PRO W7700 wins decisively in any workload that relies on standard graphics APIs. Its Geekbench Vulkan score of 129706 places it ahead of several NVIDIA workstation cards, including the RTX 4000 SFF Ada Generation with an average score of 117088 and the RTX A5500 Mobile at 113944. The OpenCL score of 108245 similarly outperforms the Tesla V100 SXM2 16 GB, which scores 114395 on average, though the delta is smaller at 4 percent. For rendering, video editing, or any GPU-accelerated application that uses OpenCL or Vulkan, the Radeon PRO W7700 provides measurable performance.

The NVIDIA H20 NVL16 wins in memory capacity and compute density. With 96 GB of HBM3 memory compared to the Radeon's 16 GB of GDDR6, the H20 NVL16 can hold far larger datasets in memory without spilling to system RAM. Its 4.03 TB/s memory bandwidth dwarfs the 576.0 GB/s of the Radeon PRO W7700, giving it a massive advantage in memory-bound workloads. The H20 NVL16 also has 312 tensor cores, which are absent from the Radeon PRO W7700 entirely, indicating that AI training and inference tasks fall squarely in the NVIDIA card's domain. The database shows no benchmark results for the H20 NVL16, meaning its measured performance remains unverified, but its hardware specifications point toward large-scale compute rather than graphics output.

Architecture Differences

The two cards come from different architectural lineages. The AMD Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture, codenamed Wheat Nas, part of the Radeon Pro Navi (Navi III Series) generation. The NVIDIA H20 NVL16 uses the GH100 chip built on Hopper architecture, part of the Server Hopper (Hxx) generation. Both are fabricated on a 5 nm process at TSMC, but the similarities end there.

Transistor counts differ dramatically. The Radeon PRO W7700 has 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The NVIDIA H20 NVL16 packs 80,000 million transistors onto an 814 mm² die, resulting in 98.3 million transistors per square millimeter. The H20 NVL16 is a physically larger and more complex chip, which aligns with its server positioning.

The Radeon PRO W7700 features 3072 shading units, 192 texture mapping units, and 96 render output units, along with 48 ray tracing cores. The H20 NVL16 has 9984 shading units, 312 texture mapping units, and only 24 render output units, plus 312 tensor cores. The low ROP count on the H20 NVL16 indicates it is not designed for pixel-heavy graphics work, while the high shading unit count suggests raw compute throughput is the priority. The Radeon PRO W7700 has no tensor cores, meaning matrix math for AI workloads is not a hardware focus.

Memory architecture reinforces the different roles. The Radeon PRO W7700 uses 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The H20 NVL16 uses 96 GB of HBM3 on a 6144-bit bus with 4.03 TB/s bandwidth. The memory clock differs as well: 2250 MHz (18 Gbps effective) for the AMD card versus 1313 MHz (5.3 Gbps effective) for the NVIDIA card, though the HBM3's wider bus compensates for the lower clock speed.

Other architectural differences include the bus interface. The Radeon PRO W7700 uses PCIe 4.0 x16, while the H20 NVL16 uses PCIe 5.0 x16. The AMD card has 4x DisplayPort 2.1 outputs, while the NVIDIA card has no display outputs at all, confirming its headless server nature. The Radeon PRO W7700 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 NVL16 reports N/A for all three graphics APIs.

The Verdict

The data indicates that the AMD Radeon PRO W7700 is the appropriate choice for graphics-intensive workstation tasks. Its Vulkan score of 129706 and OpenCL score of 108245 demonstrate measurable performance in standard GPU compute APIs. The 95th percentile ranking among all GPUs places it in the upper tier of graphics hardware. Its 16 GB of GDDR6 memory, 576.0 GB/s bandwidth, and 249.6 GPixel/s pixel rate support demanding display workloads. The 4x DisplayPort 2.1 outputs provide direct display connectivity, and the 190 W TDP with a 450 W suggested PSU makes it suitable for a dual-slot workstation card.

The NVIDIA H20 NVL16 is the choice for memory-heavy compute and AI workloads, based on its specifications. The 96 GB HBM3 memory with 4.03 TB/s bandwidth provides an order-of-magnitude advantage in memory capacity and bandwidth over the Radeon PRO W7700. The 312 tensor cores are specifically designed for matrix operations common in neural network training and inference. The 9984 shading units deliver 39.54 TFLOPS FP32 performance, exceeding the Radeon's 31.95 TFLOPS. The lack of display outputs and graphics API support means this card is not meant for visualization. The 400 W TDP and 800 W suggested PSU confirm it belongs in a server chassis, not a desktop workstation.

The database contains no benchmark scores for the H20 NVL16, so its real-world performance cannot be verified from recorded data. The Radeon PRO W7700 has concrete scores that can be compared against rivals. Given the absence of measured performance for the H20 NVL16, any performance claims about it must rely solely on its architectural specifications.
