AMD Radeon RX 7700S vs NVIDIA H20 Comparison

The AMD Radeon RX 7700S and NVIDIA H20 occupy entirely different segments of the GPU market, and benchmark data confirms this split. The RX 7700S is a mobile gaming GPU with a measured average benchmark score of 33,849, placing it in the 78th percentile of all GPUs. The H20, by contrast, is a server accelerator with no recorded benchmark scores in the database and a 50th percentile ranking that reflects its lack of standardized gaming or compute tests. For any user comparing these two, the verdict is immediate: the RX 7700S is the only option with validated performance data, while the H20 is a specialized compute device whose capabilities are not captured by the same metrics.

The Verdict

The RX 7700S is the clear choice for any workload that relies on the recorded benchmarks. Its average score of 33,849 comes from three tests: 3DMark Steel Nomad DX12 at 2,185, Geekbench OpenCL at 62,983, and Geekbench Vulkan at 36,380. These numbers place it just 0.3% behind the AMD Radeon HD 7950 (average 33,951) and 0.4% behind the AMD Radeon RX 480 (average 33,997), while running 0.5% ahead of the NVIDIA GeForce GTX 1060 5 GB (average 33,694) and 0.7% ahead of the NVIDIA RTX A5000 (average 33,622). The data shows a GPU that sits in a tight performance cluster around the 34,000 average score mark, with all four nearest rivals within a 1% band. The 78th percentile ranking confirms that this is a mid-to-upper tier part, but not a flagship.

The H20 delivers no benchmark scores in the database, so there is no measured basis for comparing its gaming or general compute performance against the RX 7700S. Its 50th percentile ranking is a placeholder, not a performance statement. The H20 is designed for server deployments, evidenced by its SXM Module slot width, 500 W TDP, 900 W suggested PSU, and lack of display outputs. The RX 7700S, with its 100 W TDP, IGP slot width, no power connectors, and portable device dependent display outputs, is built for laptops. Users who need a GPU for a mobile workstation or gaming laptop should select the RX 7700S, as it has verified performance data. Users who need a server accelerator for high-bandwidth memory and massive compute throughput should consider the H20, but they must accept that no benchmark scores exist to quantify its performance in the database.

Architecture Differences

The two GPUs are built on different architectures from different generations. The RX 7700S uses the RDNA 3.0 architecture on the Navi 33 chip, with the codename Hotpink Bonefish, and belongs to the Navi Mobile (RX 7000M) generation. It is fabricated on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2M per mm². The H20 uses the Hopper architecture on the GH100 chip, belongs to the Server Hopper (Hxx) generation, and is fabricated on a 5 nm process at TSMC, with 80,000 million transistors on an 814 mm² die, yielding a transistor density of 98.3M per mm². The H20 has over six times the transistor count and a die that is four times larger, but it also draws five times the power.

Memory architecture differs fundamentally. The RX 7700S has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth with a memory clock of 2250 MHz (18 Gbps effective). The H20 has 96 GB of HBM3 memory on a 6144-bit bus, delivering 4.03 TB/s of bandwidth with a memory clock of 1313 MHz (5.3 Gbps effective). The H20 offers 14 times the memory capacity and 14 times the bandwidth. The RX 7700S uses a PCIe 4.0 x16 interface, while the H20 uses PCIe 5.0 x16. The RX 7700S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the H20 lists N/A for DirectX, OpenGL, and Vulkan, reflecting its compute-focused design.

Compute resources show a similar divergence. The RX 7700S has 2,048 shading units, 128 texture mapping units, 64 raster output units, and 32 ray tracing cores, with no tensor cores. The H20 has 9,984 shading units, 312 texture mapping units, 24 raster output units, no ray tracing cores, and 312 tensor cores. The H20 has nearly five times the shading units and 2.4 times the texture units, but the RX 7700S has a higher pixel rate at 160.0 GPixel/s versus 47.52 GPixel/s. The RX 7700S achieves 320.0 GTexel/s texture rate versus 617.8 GTexel/s for the H20. Floating point performance shows the H20 ahead: 39.54 TFLOPS FP32 versus 20.48 TFLOPS, and 79.07 TFLOPS FP16 (2:1) versus 40.96 TFLOPS (2:1).

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two GPUs, and the H20 has an empty benchmark list. This means no direct comparison scores exist. The RX 7700S has three recorded benchmark scores, and its performance can be evaluated against its nearest rivals. The H20 offers no such data. The wins breakdown shows zero wins for each GPU in head-to-head tests, because no such tests were run.

The RX 7700S scores 2,185 in 3DMark Steel Nomad DX12, which is a modern DirectX 12 test. Its Geekbench OpenCL score of 62,983 shows strong compute throughput for a 100 W mobile part. Its Geekbench Vulkan score of 36,380 indicates solid Vulkan API performance. These three scores produce an average of 33,849, which positions the RX 7700S in the 78th percentile of all GPUs. The nearest rival comparison shows the RX 7700S is 0.3% behind the AMD Radeon HD 7950, 0.4% behind the AMD Radeon RX 480, 0.5% ahead of the NVIDIA GeForce GTX 1060 5 GB, and 0.7% ahead of the NVIDIA RTX A5000. The tight clustering of these rivals, all within a 1% spread, shows that the RX 7700S delivers performance comparable to a range of older desktop GPUs.

The H20 has no benchmark scores, no average score, and no nearest rivals. Its percentile rank of 50 is a default value, not a measured result. The absence of data means the H20 cannot be placed on the same performance scale as the RX 7700S. The only quantitative comparisons available are architectural, such as the H20's 39.54 TFLOPS FP32 versus the RX 7700S's 20.48 TFLOPS, and the H20's 4.03 TB/s memory bandwidth versus 288.0 GB/s. These numbers indicate theoretical compute and bandwidth advantages for the H20, but no benchmark scores confirm real-world results.

Where Each One Wins

The RX 7700S wins in every area where benchmark data exists. Its average score of 33,849, 78th percentile ranking, and three recorded benchmarks make it the only GPU of the two with measurable performance. It wins on pixel rate with 160.0 GPixel/s versus 47.52 GPixel/s, meaning it can fill frames faster, which is relevant for rasterization workloads. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for gaming and graphics applications. Its 100 W TDP and IGP slot width indicate it is designed for portable devices, and the absence of power connectors confirms a mobile form factor. The RX 7700S also wins on efficiency per watt in the measured data, since its 20.48 TFLOPS FP32 at 100 W compares favorably to the H20's 39.54 TFLOPS at 500 W, though the H20 still has higher absolute throughput.

The H20 wins on raw specifications that matter for server compute. It has 96 GB of HBM3 memory versus 8 GB of GDDR6, which is a 12x capacity advantage. Its 4.03 TB/s bandwidth versus 288.0 GB/s is a 14x advantage, critical for large data sets. It has 9,984 shading units versus 2,048, 312 tensor cores versus none, and 312 TMUs versus 128. Its FP32 of 39.54 TFLOPS and FP16 of 79.07 TFLOPS are roughly double the RX 7700S's 20.48 and 40.96 TFLOPS. The H20 uses a 6144-bit memory bus versus 128-bit, and PCIe 5.0 x16 versus PCIe 4.0 x16. It has a 500 W TDP and requires a 900 W suggested PSU, indicating a server environment with adequate power delivery. The H20 has no display outputs, confirming it is not intended for graphics display.

The release timeline also distinguishes them: the RX 7700S launched on January 3, 2023, and the H20 on January 31, 2024. The RX 7700S predecessor is Polaris Mobile, while the H20 predecessor is Server Ada and successor is Server Blackwell. For any workload that requires the recorded benchmarks, the RX 7700S is the only GPU with data to support a decision. For workloads that demand massive memory capacity, tensor core acceleration, and high bandwidth, the H20 offers the specifications, but no benchmark scores validate its performance in the database. The data shows two different tools for two different jobs, with only the RX 7700S having measured results to stand on.
