AMD Radeon RX 9050 vs NVIDIA H800 SXM5 Comparison

Head-to-Head Benchmarks

The database does not contain any recorded head-to-head benchmark results for the AMD Radeon RX 9050 versus the NVIDIA H800 SXM5. Neither GPU has a listed average benchmark score, and the wins counter shows zero for both sides. This absence of direct measurement data means that any comparison between these two accelerators must be drawn strictly from their architectural and specification sheets, not from empirical performance runs.

What the recorded data does show is that both parts sit at the 50th percentile among all GPUs in the database. That percentile value is a neutral placement, indicating that neither card has an outlier standing relative to the broader field. Without benchmark scores, however, the percentile alone cannot quantify the gap between them. The only concrete numbers available for comparison are the theoretical throughput figures listed in their specifications, which can serve as a proxy for peak compute capability rather than real-world application performance.

The FP32 throughput figures reveal the largest raw compute divide. The NVIDIA H800 SXM5 delivers 59.30 TFLOPS of single-precision compute, while the AMD Radeon RX 9050 provides 10.65 TFLOPS. That is a 5.57x difference in favor of the H800 in pure FP32 peak throughput. For FP16 workloads, the gap widens dramatically: the H800 reaches 237.2 TFLOPS with a 4:1 ratio, whereas the RX 9050 manages 10.65 TFLOPS with a 1:1 ratio. The NVIDIA part therefore offers 22.3x the FP16 peak of the AMD card.

On the memory side, the H800 SXM5 shows 3.36 TB/s of bandwidth from its HBM3 stack, versus 288.0 GB/s for the RX 9050's GDDR6 memory. That difference is a factor of 11.7x. The texture rate also favors NVIDIA: 926.6 GTexel/s compared to 166.4 GTexel/s, a 5.57x advantage. Pixel rate is the one metric where AMD leads, with 166.4 GPixel/s against 42.12 GPixel/s for the H800, a 3.95x margin in favor of the RX 9050.

These figures indicate that the H800 SXM5 is oriented toward compute-heavy FP16 and FP32 workloads with massive memory bandwidth, while the RX 9050 is a rasterization-oriented part with a higher pixel throughput. Neither has a recorded benchmark victory, so the head-to-head section must rely on these specification-derived comparisons alone.

Architecture Differences

The AMD Radeon RX 9050 uses the Navi 44 chip built on the RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. Its die size is 199 mm² with 29,700 million transistors, producing a transistor density of 149.2M per mm². This is a consumer-facing graphics architecture with 1,024 shading units, 64 TMUs, 64 ROPs, and 16 RT cores. The RX 9050 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and it includes display outputs: 1x HDMI 2.1b and 2x DisplayPort 2.1a.

The NVIDIA H800 SXM5 uses the GH100 chip built on the Hopper architecture, fabricated on a 5 nm process at TSMC. Its die size is 814 mm² with 80,000 million transistors, yielding a transistor density of 98.3M per mm². This is a server-oriented part with 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The H800 has no listed RT cores, no display outputs, and no recorded API support for DirectX, OpenGL, or Vulkan. It is designed as a compute module rather than a graphics card.

The two chips differ fundamentally in their target roles. The RX 9050 is a Radeon RX 9000 series product from the Navi IV generation, with a predecessor in Navi III. The H800 SXM5 belongs to the Server Hopper generation, with a predecessor in Server Ada and a successor in Server Blackwell. The RX 9050 has no listed successor. The architectural lineage points to different markets: AMD's RDNA 4.0 for client graphics, NVIDIA's Hopper for datacenter acceleration.

The tensor core count is a major architectural separator. The H800 SXM5 includes 528 tensor cores, while the RX 9050 lists no tensor cores at all. Conversely, the RX 9050 includes 16 RT cores, while the H800 SXM5 lists no RT core count. This suggests the H800 is optimized for matrix math and AI workloads, while the RX 9050 retains hardware ray tracing for graphics rendering.

Specification Differences

The two GPUs differ across nearly every recorded specification field. Process node: the RX 9050 uses 4 nm, the H800 SXM5 uses 5 nm. Transistor count: 29,700 million versus 80,000 million. Die size: 199 mm² versus 814 mm². Transistor density: 149.2M per mm² versus 98.3M per mm².

Clock speeds differ substantially. The RX 9050 has a base clock of 1330 MHz and a boost of 2600 MHz, plus a game clock of 1920 MHz. The H800 SXM5 has a base of 1095 MHz and a boost of 1755 MHz, with no game clock listed. Memory clocks also differ: the RX 9050 runs at 2250 MHz with 18 Gbps effective, while the H800 runs at 1313 MHz with 5.3 Gbps effective.

Memory configuration is a major split. The RX 9050 has 8 GB of GDDR6 on a 128-bit bus, yielding 288.0 GB/s. The H800 SXM5 has 80 GB of HBM3 on a 5120-bit bus, yielding 3.36 TB/s. The H800 has 10x the memory capacity and 11.7x the bandwidth.

Compute resources differ sharply. Shading units: 1,024 versus 16,896. TMUs: 64 versus 528. ROPs: 64 versus 24. RT cores: 16 versus none listed. Tensor cores: none listed versus 528. The RX 9050 has more ROPs, while the H800 dominates in shading units, TMUs, and tensor cores.

Throughput figures follow the resource counts. The RX 9050 produces 166.4 GPixel/s and 166.4 GTexel/s. The H800 produces 42.12 GPixel/s and 926.6 GTexel/s. FP32 is 10.65 TFLOPS versus 59.30 TFLOPS. FP16 is 10.65 TFLOPS (1:1) versus 237.2 TFLOPS (4:1).

Power and physical specifications diverge as well. The RX 9050 has a TDP of 92 W, uses a dual-slot cooler with a 1x 8-pin power connector, and suggests a 250 W PSU. The H800 SXM5 has a TDP of 700 W, comes as an SXM module with an 8-pin EPS connector, and suggests an 1100 W PSU. Both use PCIe 5.0 x16. The RX 9050 has display outputs; the H800 has none. The RX 9050 was released on 2026-07-27, while the H800 was released on 2023-03-20.

The Verdict

The recorded data points to two entirely different use cases with no overlap in their intended environments. The AMD Radeon RX 9050 is a client graphics card with a 92 W TDP, display outputs, and a pixel rate of 166.4 GPixel/s. It is built for rendering workloads that benefit from high ROP throughput and ray tracing hardware. The NVIDIA H800 SXM5 is a server compute module with a 700 W TDP, no display outputs, and a tensor core count of 528. Its 237.2 TFLOPS of FP16 throughput and 3.36 TB/s of bandwidth place it firmly in the datacenter acceleration category.

For rasterization-oriented tasks, the RX 9050 shows a clear advantage in pixel fill rate, leading by 3.95x. For compute-heavy tasks, the H800 leads in FP32 by 5.57x, in FP16 by 22.3x, in texture rate by 5.57x, and in memory bandwidth by 11.7x. The choice between them depends entirely on whether the workload is graphics output or general computation.

The RX 9050 belongs in a system with a display, a standard power supply, and a need for DirectX 12 Ultimate or Vulkan 1.4 support. The H800 SXM5 belongs in a server chassis with high-power delivery, no display requirement, and a need for tensor-core acceleration. Neither card can substitute for the other in their respective domains.

Where Each One Wins

The AMD Radeon RX 9050 wins in pixel fill rate with 166.4 GPixel/s against 42.12 GPixel/s for the H800 SXM5. This makes it the better fit for workloads that stress ROP throughput, such as high-resolution rasterization with heavy overdraw. It also has 16 RT cores, a feature the H800 does not list, so ray-traced rendering is an area where the RX 9050 has hardware support that the H800 lacks. The RX 9050 supports display outputs and standard graphics APIs, while the H800 has no display outputs and no listed API support. The RX 9050 also runs at a much lower TDP of 92 W versus 700 W, requiring a 250 W PSU rather than 1100 W.

The NVIDIA H800 SXM5 wins in every compute and memory metric that matters for datacenter workloads. Its FP32 throughput of 59.30 TFLOPS is 5.57x the RX 9050's 10.65 TFLOPS. Its FP16 throughput of 237.2 TFLOPS is 22.3x higher. Its texture rate of 926.6 GTexel/s is 5.57x higher. Its memory bandwidth of 3.36 TB/s is 11.7x higher, and its 80 GB capacity is 10x the RX 9050's 8 GB. The 528 tensor cores give it a dedicated path for matrix operations, while the RX 9050 has no tensor core count listed.

The H800 also leads in shading units (16,896 versus 1,024) and TMUs (528 versus 64), which supports its higher texture and compute throughput. The RX 9050 leads in ROPs (64 versus 24), which explains its higher pixel rate. The H800 uses HBM3 memory with a 5120-bit bus, while the RX 9050 uses GDDR6 with a 128-bit bus. The H800 is a server module with an 8-pin EPS connector and no display outputs; the RX 9050 is a dual-slot card with a 1x 8-pin connector and HDMI and DisplayPort outputs.

In terms of production status, both are listed as Active. The H800 has a predecessor and a successor in the server Hopper line, while the RX 9050 has a predecessor but no successor. The release dates place the H800 at 2023-03-20 and the RX 9050 at 2026-07-27. The data shows that the H800 is a mature server product, while the RX 9050 is a newer client part. Each wins in the domain where its specification sheet is strongest, and the benchmark database currently holds no direct comparison to override those specification-based conclusions.
