NVIDIA GeForce RTX 5080 SUPER vs NVIDIA H20 NVL16 Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark result for the NVIDIA GeForce RTX 5080 SUPER: a 3DMark Steel Nomad DX12 score of 3075 points. This places the card at the 19th percentile among all GPUs in the database. The NVIDIA H20 NVL16, by contrast, has no benchmark entries, an average benchmark score of zero, and sits at the 50th percentile based on its overall classification rather than any measured performance.

Because the H20 NVL16 lacks any recorded benchmark scores, there is no direct head-to-head comparison available. The RTX 5080 SUPER’s score is the only measurable data point. The nearest rivals for the RTX 5080 SUPER in the database are the NVIDIA Quadro P1000, Intel Arc Pro B60, NVIDIA GeForce 820A, and NVIDIA GeForce GTX 860M. The RTX 5080 SUPER trails the Quadro P1000 by 2.8% (3163 vs. 3075), sits 3.1% ahead of the GeForce 820A (2983 vs. 3075), lags the Arc Pro B60 by 3.4% (3182 vs. 3075), and leads the GTX 860M by 3.6% (2967 vs. 3075). These deltas are narrow, indicating that the RTX 5080 SUPER’s measured performance in this specific test is tightly clustered with those legacy and entry-level parts, despite the massive architectural and specification differences.

The H20 NVL16’s lack of benchmark data means it cannot be ranked against the RTX 5080 SUPER or any other GPU in the database based on measured results. The percentile field for the H20 NVL16 (50th percentile) is not derived from a benchmark score, as its average score is zero, so it should not be interpreted as a performance ranking. The RTX 5080 SUPER’s 19th percentile, however, is directly tied to its Steel Nomad score of 3075, which is the sole benchmark result in its record.

The Verdict

The data supports a straightforward split: the RTX 5080 SUPER is the only one of the two with any recorded benchmark performance. Its 3DMark Steel Nomad DX12 score of 3075 is the sole measurable result, and it places the card at the 19th percentile overall. The H20 NVL16 has no benchmark entries whatsoever, so any performance comparison between the two is impossible from the recorded data.

The H20 NVL16 is positioned as a server-grade module with 96 GB of HBM3 memory, a 6144-bit bus, and 4.03 TB/s of bandwidth. Its FP16 throughput is 79.07 TFLOPS, which is double its FP32 rate of 39.54 TFLOPS, indicating a design optimized for mixed-precision workloads. The RTX 5080 SUPER, by contrast, delivers 56.28 TFLOPS in both FP32 and FP16 (1:1 ratio), which is typical for a consumer graphics card. The H20 NVL16 also draws 400 W with a suggested PSU of 800 W, while the RTX 5080 SUPER has a TDP of 415 W and uses a single 16-pin connector.

For buyers focused purely on measured graphics performance, the RTX 5080 SUPER is the only option with any benchmark data. Its 3075 Steel Nomad score, while modest relative to the 50th-percentile baseline, is at least quantifiable. The H20 NVL16 offers no such evidence, and its zero average benchmark score means it cannot be selected based on performance metrics. The H20 NVL16’s role, based on the specification record, is clearly a high-memory server accelerator with no display outputs and no DirectX, OpenGL, or Vulkan API support, making it unsuitable for standard graphics workloads. The RTX 5080 SUPER supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and includes display outputs (1x HDMI 2.1b, 3x DisplayPort 2.1b), confirming its consumer graphics focus.

Architecture Differences

The two GPUs come from different architectures within NVIDIA’s lineup. The RTX 5080 SUPER is based on the GB203 chip using Blackwell 2.0 architecture, part of the GeForce 50-series generation. The H20 NVL16 uses the GH100 chip with Hopper architecture, part of the Server Hopper (Hxx) generation. Both are manufactured by TSMC on a 5 nm process, but the transistor counts and die sizes diverge sharply: the GB203 contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per mm², while the GH100 contains 80,000 million transistors on an 814 mm² die, with a density of 98.3 million per mm².

The memory architectures are fundamentally different. The RTX 5080 SUPER uses GDDR7 with a 256-bit bus, while the H20 NVL16 uses HBM3 with a 6144-bit bus, which accounts for the latter’s 4.03 TB/s bandwidth versus 1.02 TB/s. The FP16 compute ratio also differs: the RTX 5080 SUPER provides FP16 at a 1:1 ratio with FP32 (56.28 TFLOPS each), whereas the H20 NVL16 provides FP16 at a 2:1 ratio (79.07 TFLOPS FP16 versus 39.54 TFLOPS FP32), indicating a stronger emphasis on tensor and reduced-precision workloads in the Hopper part.

The RTX 5080 SUPER includes dedicated RT cores (84 of them) and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, plus display outputs. The H20 NVL16 lists no RT cores and no API support, and has no display outputs, consistent with a server accelerator designed for compute rather than graphics rendering. The H20 NVL16’s form factor is an SXM module, whereas the RTX 5080 SUPER is a dual-slot PCIe card with a 16-pin power connector. The H20 NVL16 also specifies a suggested PSU of 800 W, while the RTX 5080 SUPER’s TDP is 415 W. These architectural differences align with the intended use cases: the RTX 5080 SUPER is a client graphics card with measured benchmark performance, while the H20 NVL16 is a server compute module with high memory capacity and bandwidth but no graphics output or API support.
