Architecture Differences

The AMD Radeon RX 7700 is built on the RDNA 3.0 architecture using the Navi 32 chip, manufactured on a 5 nm process at TSMC. It belongs to the Radeon RX 7000 series with the codename Wheat Nas, representing the Navi III generation. The NVIDIA H20 uses the Hopper architecture with the GH100 chip, also on a 5 nm process at TSMC, and belongs to the Server Hopper generation.

The transistor density differs meaningfully between the two. The AMD chip contains 28,100 million transistors on a 346 mm² die, yielding a density of 81.2 million transistors per square millimeter. The NVIDIA chip packs 80,000 million transistors onto an 814 mm² die, achieving a higher density of 98.3 million transistors per square millimeter.

Shader resources diverge sharply. The AMD Radeon RX 7700 includes 2560 shading units, 160 texture mapping units, 96 render output units, and 40 ray tracing cores. The NVIDIA H20 has 9984 shading units, 312 texture mapping units, 24 render output units, and 312 tensor cores, with no ray tracing core count recorded.

The NVIDIA H20 lists tensor cores as a core feature, reflecting its server-oriented design, while the AMD card has no tensor core entry. The AMD card lists DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API support. The NVIDIA H20 lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for conventional graphics API workloads.

Clock behavior also differs. The AMD Radeon RX 7700 has a base clock of 1900 MHz, a boost clock of 2459 MHz, and a game clock of 2041 MHz. The NVIDIA H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz, with no game clock listed. The AMD memory runs at 2438 MHz with 19.5 Gbps effective speed, while the NVIDIA memory runs at 1313 MHz with 5.3 Gbps effective speed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon RX 7700 versus the NVIDIA H20. The head-to-head list is empty, and both win counters are zero. Consequently, any comparison must rely on the individual benchmark data recorded for the AMD card and the architectural specifications for the NVIDIA card.

The AMD Radeon RX 7700 has a full set of recorded benchmark results. Its 3DMark Steel Nomad DX12 score is 2865. In Geekbench OpenCL, it scores 106028. The PassMark suite shows a G3D score of 20974, a GPU compute score of 10963, and a G2D score of 1206. Legacy DirectX scores are 92 for DirectX 10, 186 for DirectX 11, 96 for DirectX 12, and 261 for DirectX 9.

The NVIDIA H20 has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and its percentile among all GPUs is 50, which is lower than the AMD card's 58th percentile. However, this percentile value for the NVIDIA H20 appears to be based on its specifications rather than measured performance, since no benchmark data exists.

The AMD Radeon RX 7700's average score of 15852 places it in close competition with several rivals. It sits 0.1% behind the AMD Radeon R9 370X, which has an average score of 15862. It trails the AMD Radeon RX 9060 by 1% (that card scores 16014) and the NVIDIA GeForce RTX 3060 Ti by 1.7% (that card scores 16129). The AMD Radeon Pro W5500 scores 15679, which puts the RX 7700 ahead by 1.1%.

The NVIDIA H20 has no nearest rivals listed in the database, so no comparative delta percentages are available for it.

Specification Differences

The two cards differ across nearly every major specification category.

The AMD Radeon RX 7700 uses 16 GB of GDDR6 memory on a 256-bit bus, providing 624.1 GB/s of bandwidth. The NVIDIA H20 uses 96 GB of HBM3 memory on a 6144-bit bus, providing 4.03 TB/s of bandwidth. The NVIDIA card has six times the memory capacity and roughly 6.5 times the bandwidth of the AMD card.

Compute throughput differs substantially. The AMD Radeon RX 7700 delivers 25.18 TFLOPS for both FP32 and FP16 at a 1:1 ratio. The NVIDIA H20 delivers 39.54 TFLOPS for FP32 and 79.07 TFLOPS for FP16 at a 2:1 ratio. The NVIDIA card is about 57% ahead in FP32 and roughly three times faster in FP16.

Pixel and texture rates also diverge. The AMD card has a pixel rate of 236.1 GPixel/s and a texture rate of 393.4 GTexel/s. The NVIDIA card has a pixel rate of 47.52 GPixel/s but a texture rate of 617.8 GTexel/s. The AMD card processes pixels much faster, while the NVIDIA card processes textures faster.

Power requirements differ by a wide margin. The AMD Radeon RX 7700 has a TDP of 200 W and a suggested PSU of 550 W. The NVIDIA H20 has a TDP of 500 W and a suggested PSU of 900 W. The AMD card uses 2x 8-pin power connectors, while the NVIDIA card has no power connector listing because it is an SXM module.

Physical dimensions are recorded for the AMD card only: 267 mm in length, 135 mm in height, and 50 mm in width, making it a dual-slot card. The NVIDIA H20 is an SXM module with no dimensions listed.

The AMD card has display outputs as listed earlier, while the NVIDIA card has no outputs. The AMD card supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The NVIDIA card lists N/A for all three APIs.

Release dates differ by about 20 months. The NVIDIA H20 was released on 2024-01-31, while the AMD Radeon RX 7700 was released on 2025-09-17. Both cards are currently marked as Active in production status.

The Verdict

The recorded data shows two fundamentally different products with separate intended roles. The AMD Radeon RX 7700 is a client graphics card with full benchmark coverage, a 58th percentile ranking, and an average score of 15852. The NVIDIA H20 is a server accelerator with no benchmark scores, no display outputs, and no conventional graphics API support.

For anyone comparing these on gaming or workstation graphics performance, the AMD Radeon RX 7700 is the only card with measured data to support a decision. Its benchmark results place it in the upper half of all GPUs, with competitive positioning against cards like the NVIDIA GeForce RTX 3060 Ti, from which it trails by 1.7%, and the AMD Radeon RX 9060, from which it trails by 1%.

The NVIDIA H20 cannot be benchmarked for graphics workloads based on the available data. Its API support is listed as N/A, it has no display outputs, and its pixel rate of 47.52 GPixel/s is far below the AMD card's 236.1 GPixel/s. The NVIDIA card's strengths lie elsewhere: 96 GB of HBM3 memory, 4.03 TB/s bandwidth, 79.07 TFLOPS of FP16 compute, and 312 tensor cores.

The data indicates that the AMD Radeon RX 7700 is designed for rendering, gaming, and general graphics tasks, while the NVIDIA H20 is designed for compute-heavy server workloads such as training and inference, where tensor cores and massive memory capacity take priority over rasterization.

Where Each One Wins

The AMD Radeon RX 7700 wins in every measurable graphics benchmark category because the NVIDIA H20 has no recorded scores. The AMD card's average benchmark score of 15852 and 58th percentile ranking provide a concrete performance baseline, whereas the NVIDIA card's 0 average score and 50th percentile offer no comparable metric.

The AMD card wins on pixel throughput with 236.1 GPixel/s versus 47.52 GPixel/s for the NVIDIA H20. This indicates a decisive advantage for the AMD card in rasterization-heavy workloads, including traditional game rendering and any application that depends on fill rate.

The AMD card also wins on API compatibility and display functionality. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and provides HDMI 2.1a, DisplayPort 2.1, and USB Type-C outputs. The NVIDIA H20 supports no graphics APIs and has no display outputs, making it unsuitable for any task that requires a monitor or a conventional graphics pipeline.

The NVIDIA H20 wins on memory capacity and bandwidth. Its 96 GB of HBM3 memory and 4.03 TB/s bandwidth dwarf the AMD card's 16 GB and 624.1 GB/s. This gives the NVIDIA card a clear advantage in large data set handling, such as model training or scientific simulation, where memory capacity directly limits problem size.

The NVIDIA H20 wins on compute throughput, particularly for FP16 workloads. Its 79.07 TFLOPS FP16 performance is roughly three times the AMD card's 25.18 TFLOPS. The NVIDIA card also has 312 tensor cores, which are absent from the AMD card, making it better suited for matrix operations common in AI workloads.

The NVIDIA H20 wins on texture processing with 617.8 GTexel/s versus 393.4 GTexel/s for the AMD card. This advantage matters in compute-heavy texture sampling scenarios, though the AMD card's higher pixel rate and graphics API support make it more practical for interactive rendering.

The NVIDIA H20 also wins on interconnect and capacity-related specifications. It uses PCIe 5.0 x16 versus PCIe 4.0 x16 on the AMD card, and it has a higher transistor count and die size. These factors point toward server deployment where bandwidth, memory, and compute density are prioritized over graphics output.
