AMD Radeon RX 7600S vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon RX 7600S and the NVIDIA H20. The RX 7600S has a full set of recorded benchmark scores, while the H20 has no benchmark entries in the database. This makes a direct comparison of measured performance impossible from the recorded data alone.

The RX 7600S delivers an average benchmark score of 16696 across its recorded tests. It places at the 60th percentile among all GPUs in the database. Its closest rivals by average score include the NVIDIA T400 4 GB at 16792, which is 0.6% faster, and the NVIDIA Tesla M4 at 16932, which is 1.4% faster. The RX 7600S also sits 1.1% ahead of the NVIDIA T400 and 1.2% ahead of the NVIDIA GeForce RTX 5090 D V2, both of which average around 16500 to 16508.

Looking at individual benchmark results for the RX 7600S, the strongest showing is in Geekbench Vulkan with a score of 73868. The Geekbench OpenCL score reaches 68012. In PassMark tests, the 3D G3D score is 15408, the G2D score is 776, and the GPU compute score is 6520. DirectX 9 produces a score of 211, DirectX 11 a score of 140, DirectX 10 a score of 74, and DirectX 12 a score of 65. The 3DMark Steel Nomad DX12 test yields 1888 points.

The H20 has no recorded benchmark scores, an average benchmark score of zero, and no nearest rivals listed. Its percentile placement is 50th among all GPUs in the database, but this is based on no measured data. The absence of results for the H20 means the database cannot confirm any performance relationship between these two parts.

The Verdict

From the recorded data, the RX 7600S is the only one of the two with actual benchmark measurements. The H20 has no benchmark entries, so any performance claim about it would be unsupported by the database.

The RX 7600S is positioned around the 60th percentile of all GPUs, with an average benchmark score of 16696. Its nearest rivals cluster within a narrow band: the NVIDIA T400 4 GB is 0.6% ahead, the Tesla M4 is 1.4% ahead, and the T400 and GeForce RTX 5090 D V2 are 1.1% and 1.2% behind, respectively. This places the RX 7600S in a competitive midrange position among the recorded scores.

The H20, in contrast, has no benchmark data. Its 50th percentile rating is not supported by any measurements. The database provides no evidence of how the H20 compares to the RX 7600S in any workload. A user selecting between these two parts based on the database would find only the RX 7600S has verified performance results. The H20 cannot be ranked against it from the available information.

Where Each One Wins

The AMD Radeon RX 7600S wins in the areas where recorded measurements exist. Its benchmark scores cover multiple API tests, and it has a 60th percentile ranking among all GPUs. The RX 7600S also wins on pixel rate at 140.8 GPixel/s, which is higher than the H20's 47.52 GPixel/s. It has more ROPs at 64 versus 24, includes 28 ray tracing cores, and supports consumer graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The RX 7600S has a lower TDP at 75 W and uses a PCIe 4.0 x16 interface.

The NVIDIA H20 wins on raw compute throughput. Its FP32 performance of 39.54 TFLOPS is more than double the RX 7600S. FP16 performance reaches 79.07 TFLOPS, also more than double. The H20 texture rate of 617.8 GTexel/s is over twice that of the RX 7600S. It has 312 tensor cores, a feature the RX 7600S does not list. Memory capacity at 96 GB and bandwidth at 4.03 TB/s are far higher than the RX 7600S. The H20 uses a newer 5 nm process node, has a larger die at 814 mm², and a higher transistor density at 98.3 million per mm². It also has a higher boost clock at 1980 MHz.

The H20 has no benchmark results and no nearest rivals in the database. This means its wins are architectural rather than measured. The RX 7600S is the only part with verified performance data, and it has a clear record across DirectX, OpenCL, Vulkan, and PassMark tests. For tasks involving ray tracing or consumer graphics APIs, the RX 7600S has the advantage. For tasks relying on FP32 or FP16 throughput, tensor cores, or large memory capacity, the H20 shows the stronger specifications, but the database contains no measured scores to confirm that advantage in practice.
