AMD Radeon RX 7700 XT vs NVIDIA H20 Comparison

Where Each One Wins

The recorded data presents a stark contrast between these two accelerators. The AMD Radeon RX 7700 XT is a client-focused graphics card with a full suite of benchmark results, while the NVIDIA H20 is a server accelerator with no benchmark entries in the database. The RX 7700 XT holds every measurable win by default, as the H20 has zero recorded scores across all test suites. The RX 7700 XT achieves an average benchmark score of 22549, placing it in the 67th percentile of all GPUs tracked. The H20 sits at the 50th percentile with an average score of 0, reflecting the absence of any benchmark submissions.

The RX 7700 XT delivers wins in every category where data exists. In 3DMark Steel Nomad DX12, it scores 3316. In Geekbench OpenCL, it posts 138383, and in Geekbench Vulkan it reaches 46443. Passmark results show 22547 in G3D, 12912 in GPU Compute, 1161 in G2D, 294 in DirectX 9, 232 in DirectX 11, 119 in DirectX 10, and 79 in DirectX 12. These figures establish the RX 7700 XT as a fully realized gaming and compute product with measurable performance across legacy and modern APIs.

The H20 offers no comparable data. Its benchmark array is empty, and its nearest rivals list contains no entries. This means the database cannot confirm any workload where the H20 outperforms the RX 7700 XT. The H20 targets a different deployment scenario: a server Hopper accelerator with 96 GB of HBM3 memory, 9984 shading units, and 312 tensor cores. Its specifications suggest a design optimized for large-scale AI inference and training, but the absence of benchmark scores leaves its real-world standing unverified in this database. The RX 7700 XT wins on every recorded metric, while the H20 wins only on paper specifications that lack empirical validation.

Architecture Differences

The two products diverge fundamentally at the architectural level. The RX 7700 XT uses the Navi 32 chip built on RDNA 3.0 architecture, codenamed Wheat Nas, and belongs to the Navi III (RX 7000) generation. It is fabricated on a 5 nm process at TSMC, containing 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The H20 uses the GH100 chip built on Hopper architecture, belongs to the Server Hopper (Hxx) generation, and is also fabricated on a 5 nm process at TSMC. The H20 packs 80,000 million transistors on a 814 mm² die, giving it a higher transistor density of 98.3 million per square millimeter.

Clock behavior separates the two clearly. The RX 7700 XT runs a base clock of 1435 MHz, a boost clock of 2544 MHz, and a game clock of 2171 MHz. Memory clocks at 2250 MHz with 18 Gbps effective. The H20 runs a base clock of 1830 MHz and a boost clock of 1980 MHz, with memory at 1313 MHz and 5.3 Gbps effective. The RX 7700 XT boosts substantially higher, reflecting its client gaming orientation. The H20's lower boost clock aligns with server workloads that prioritize sustained throughput over peak frequency.

Memory architecture differs completely. The RX 7700 XT has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The H20 has 96 GB of HBM3 on a 6144-bit bus, delivering 4.03 TB/s of bandwidth. The H20's memory subsystem offers roughly nine times the capacity and nearly ten times the bandwidth, a design choice for large models and datasets in AI inference. The RX 7700 XT's smaller memory pool suits gaming and conventional graphics workloads.

Compute resources also diverge. The RX 7700 XT has 3456 shading units, 216 texture mapping units, 96 raster operations units, and 54 ray tracing cores. It has no tensor cores. The H20 has 9984 shading units, 312 texture mapping units, 24 raster operations units, no ray tracing cores, and 312 tensor cores. The H20's tensor core count signals its AI focus, while the RX 7700 XT's ray tracing cores serve real-time graphics. Pixel rate favors the RX 7700 XT at 244.2 GPixel/s versus 47.52 GPixel/s for the H20. Texture rate slightly favors the H20 at 617.8 GTexel/s versus 549.5 GTexel/s for the RX 7700 XT.

Floating-point performance shows a nuanced split. The RX 7700 XT delivers 35.17 TFLOPS for both FP32 and FP16, a 1:1 ratio. The H20 delivers 39.54 TFLOPS for FP32 and 79.07 TFLOPS for FP16, a 2:1 ratio. The H20 leads in raw FP32 and doubles its FP16 throughput, while the RX 7700 XT does not accelerate FP16 beyond its FP32 rate. API support also separates them: the RX 7700 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 lists N/A for all three APIs, confirming it is not a graphics-oriented product.

The Verdict

The data points to a straightforward conclusion: these products serve separate markets, and the RX 7700 XT is the only one with verified performance. The RX 7700 XT has a complete benchmark profile, a 67th percentile ranking among all GPUs, and an average score of 22549. The H20 has no benchmark scores, a 50th percentile ranking, and an average score of 0. Anyone seeking a graphics card with confirmed gaming and compute capabilities should choose the RX 7700 XT based on the recorded evidence. The H20 cannot be recommended for any graphics workload because the database contains zero measurements of its performance.

The H20's specifications indicate a different purpose. Its 96 GB HBM3 memory, 4.03 TB/s bandwidth, 312 tensor cores, and 79.07 TFLOPS FP16 throughput position it for server-side AI inference and training. Its lack of display outputs, lack of DirectX support, and SXM module form factor confirm it is not intended for desktop use. The RX 7700 XT, with its display outputs, ray tracing cores, and DirectX 12 Ultimate support, is built for interactive graphics. The choice between them depends on workload: the RX 7700 XT for rendering and gaming, the H20 for AI compute, but only the RX 7700 XT has data to back its claims.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark entries between the RX 7700 XT and the H20. This absence is itself informative: the H20 has no recorded scores in any test, so no direct comparison is possible. The RX 7700 XT stands alone with its ten benchmark results, each representing a data point the H20 cannot match.

The RX 7700 XT's strongest recorded result is in Geekbench OpenCL, where it scores 138383. This number dwarfs its other submissions and indicates strong compute throughput in that specific test. In Geekbench Vulkan, it scores 46443, showing solid graphics API performance. The 3DMark Steel Nomad DX12 score of 3316 provides a modern DirectX 12 workload result. Passmark G3D gives 22547, which aligns closely with the card's average benchmark score of 22549, suggesting the G3D test is representative of its overall standing.

Passmark results show a wide spread across API generations. DirectX 9 scores 294, DirectX 11 scores 232, DirectX 10 scores 119, and DirectX 12 scores 79. The lower DirectX 12 score relative to DirectX 9 is notable, as it suggests the card's performance profile varies significantly by API. Passmark GPU Compute scores 12912, and G2D scores 1161. These numbers provide a complete picture of the RX 7700 XT's capabilities, while the H20 contributes no comparable data.

The RX 7700 XT's nearest rivals in the database include the NVIDIA GeForce RTX 5060 Mobile with an average score of 22435 and a delta of 0.5 percent, the NVIDIA GeForce RTX 4060 Mobile with 22729 and a delta of -0.8 percent, the NVIDIA GeForce RTX 2080 with 22895 and a delta of -1.5 percent, and the AMD Radeon RX 5700 with 22170 and a delta of 1.7 percent. These deltas show the RX 7700 XT is tightly clustered with these four products, within 1.7 percent either way. The H20 has no rivals listed, reinforcing its isolation from the benchmark ecosystem.
