NVIDIA GeForce RTX 5080 SUPER vs NVIDIA H800 SXM5 Comparison

Head-to-Head Benchmarks

The database contains a single recorded benchmark for the NVIDIA GeForce RTX 5080 SUPER, the 3DMark Steel Nomad DX12 test, where it scores 3075 points. This places the card in the 19th percentile of all GPUs tracked in the database. The H800 SXM5 has no benchmark entries in the database, so no direct head-to-head comparison can be made from measured results.

The RTX 5080 SUPER's nearest rivals in the database provide context for its score. The Intel Arc Pro B60 averages 3182 points, which is 3.4% ahead of the RTX 5080 SUPER. The NVIDIA Quadro P1000 averages 3163 points, 2.8% ahead. The RTX 5080 SUPER sits ahead of two other rivals: the NVIDIA GeForce 820A averages 2983 points, which is 3.1% behind the RTX 5080 SUPER, and the NVIDIA GeForce GTX 860M averages 2967 points, 3.6% behind. These deltas are narrow, indicating that the RTX 5080 SUPER's measured performance clusters tightly with a group of GPUs spanning roughly a 7% total spread from the GTX 860M to the Arc Pro B60.

The H800 SXM5, by contrast, has no recorded benchmark average and no nearest rivals listed. The database shows a 50th percentile placement for the H800 SXM5 despite the zero average score, which reflects its position in the overall GPU distribution based on other recorded characteristics rather than measured benchmark results.

Because the head-to-head benchmark array is empty, the data does not support any claim of a direct performance advantage for either product in a shared workload. The RTX 5080 SUPER has one measurable data point; the H800 SXM5 has none.

Where Each One Wins

The RTX 5080 SUPER wins in measured graphics performance, as it is the only one of the two with a recorded benchmark result. Its 3075-point score in 3DMark Steel Nomad DX12 demonstrates that it can complete a modern DirectX 12 graphics workload, which is consistent with its consumer-oriented feature set. The card's nearest rival deltas show it performs within a few percentage points of several other GPUs in the database, so its victory here is not by a large margin but it is a verified result.

The H800 SXM5 wins in the absence of any recorded graphics benchmark. That absence is not a performance claim; it simply reflects that the database contains no measured result for this product. The H800 SXM5's 50th percentile placement, while not derived from a benchmark score, suggests that its overall characteristics place it in the middle of the database distribution.

In compute-oriented scenarios, the H800 SXM5's recorded specifications point to a different strengths: its FP16 throughput of 237.2 TFLOPS (4:1 ratio) is substantially higher than the RTX 5080 SUPER's FP16 figure of 56.28 TFLOPS (1:1 ratio). The H800 SXM5 also has a significantly wider memory bus at 5120 bit and a larger memory pool at 80 GB. These factors favor the H800 SXM5 in workloads that stress memory capacity or half-precision compute, though no benchmark data confirms this directly.

Specification Differences

The two cards differ across nearly every major specification category. The RTX 5080 SUPER uses the GB203 chip with a 5 nm process, while the H800 SXM5 uses the GH100 chip also on a 5 nm process. The RTX 5080 SUPER has 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². The H800 SXM5 has 80,000 million transistors on a much larger 814 mm² die, with a lower transistor density of 98.3M per mm².

Clock speeds differ substantially. The RTX 5080 SUPER runs at a base clock of 2295 MHz and a boost clock of 2617 MHz. The H800 SXM5 runs at a base clock of 1095 MHz and a boost clock of 1755 MHz, which is roughly half the base clock and two-thirds of the boost clock of the RTX 5080 SUPER.

Memory configurations are entirely different. The RTX 5080 SUPER has 24 GB of GDDR7 on a 256 bit bus with 1.02 TB/s bandwidth. The H800 SXM5 has 80 GB of HBM3 on a 5120 bit bus with 3.36 TB/s bandwidth. The H800 SXM5's memory clock is recorded as 1313 MHz with 5.3 Gbps effective, while the RTX 5080 SUPER's memory clock is 2000 MHz with 32 Gbps effective.

Compute unit counts differ: the RTX 5080 SUPER has 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The H800 SXM5 has 16896 shading units, 528 TMUs, 24 ROPs, no recorded RT cores, and 528 tensor cores. The pixel rate is 293.1 GPixel/s for the RTX 5080 SUPER versus 42.12 GPixel/s for the H800 SXM5. The texture rate is 879.3 GTexel/s for the RTX 5080 SUPER versus 926.6 GTexel/s for the H800 SXM5.

FP32 throughput is 56.28 TFLOPS for the RTX 5080 SUPER and 59.30 TFLOPS for the H800 SXM5, a narrow gap. FP16 throughput differs by a factor of four: 56.28 TFLOPS (1:1) for the RTX 5080 SUPER versus 237.2 TFLOPS (4:1) for the H800 SXM5.

Power and physical specifications also diverge. The RTX 5080 SUPER has a TDP of 415 W, uses a dual-slot design, and requires a single 16-pin power connector. The H800 SXM5 has a TDP of 700 W, comes as an SXM module, uses an 8-pin EPS connector, and lists a suggested PSU of 1100 W.

The RTX 5080 SUPER provides display outputs (1x HDMI 2.1b and 3x DisplayPort 2.1b) and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H800 SXM5 has no display outputs and lists no API support in the database.

Dimensions are recorded for the RTX 5080 SUPER (304 mm length, 137 mm height, 40 mm width) but are not recorded for the H800 SXM5.

Architecture Differences

The RTX 5080 SUPER is built on the Blackwell 2.0 architecture and belongs to the GeForce 50-series generation. The H800 SXM5 is built on the Hopper architecture and belongs to the Server Hopper (Hxx) generation. Both use a 5 nm process from TSMC, but they target different market segments: the RTX 5080 SUPER is a consumer graphics card, while the H800 SXM5 is a server module.

The RTX 5080 SUPER includes 84 RT cores for hardware ray tracing, which the H800 SXM5 does not list. The RTX 5080 SUPER also has a much higher ROP count (112 versus 24), which aligns with its role as a rasterization-focused graphics product. The H800 SXM5's lower ROP count and higher texture rate (926.6 GTexel/s versus 879.3 GTexel/s) suggest a compute-oriented design rather than a graphics-oriented one.

The H800 SXM5's FP16 throughput of 237.2 TFLOPS at a 4:1 ratio indicates that it is designed for mixed-precision compute workloads where half-precision arithmetic is heavily used. The RTX 5080 SUPER's FP16 throughput matches its FP32 throughput at 56.28 TFLOPS, indicating a 1:1 ratio that is typical of consumer graphics architectures.

The RTX 5080 SUPER's memory system uses GDDR7, a consumer-oriented memory type, while the H800 SXM5 uses HBM3, a high-bandwidth memory type aimed at data center and server workloads. The H800 SXM5's 5120 bit bus width is twenty times wider than the RTX 5080 SUPER's 256 bit bus, though the RTX 5080 SUPER compensates with a much higher effective memory clock (32 Gbps versus 5.3 Gbps effective).

The H800 SXM5 has a predecessor listed as "Server Ada" and a successor listed as "Server Blackwell," placing it in a server product line. The RTX 5080 SUPER has no predecessor or successor listed in the database. The RTX 5080 SUPER's release date is recorded as 2025-12-31, while the H800 SXM5's release date is 2023-03-20.

The Verdict

The data presents two products with fundamentally different purposes. The RTX 5080 SUPER is a consumer graphics card with a verified 3DMark Steel Nomad DX12 score of 3075 points, display outputs, and a full graphics API stack. Its nearest rivals in the database are within a narrow band: the highest rival (Intel Arc Pro B60) is 3.4% ahead, and the lowest (NVIDIA GeForce GTX 860M) is 3.6% behind. This places the RTX 5080 SUPER in a competitive mid-range position for graphics workloads.

The H800 SXM5 has no recorded benchmark results, so any performance comparison must rely on its recorded specifications. Its FP32 throughput of 59.30 TFLOPS is slightly higher than the RTX 5080 SUPER's 56.28 TFLOPS, and its FP16 throughput of 237.2 TFLOPS is over four times higher. Its memory bandwidth of 3.36 TB/s is more than three times the RTX 5080 SUPER's 1.02 TB/s, and its 80 GB memory capacity is more than triple the RTX 5080 SUPER's 24 GB.

The choice between these two products depends on workload characteristics. For graphics rendering, rasterization, ray tracing, and display output, the RTX 5080 SUPER is the only one with measured data and the only one with the necessary hardware features: RT cores, display outputs, and graphics API support. For compute-heavy workloads that rely on half-precision arithmetic and very large memory pools, the H800 SXM5's specifications indicate a clear advantage, though the database contains no benchmark result to confirm this.

The RTX 5080 SUPER's 19th percentile placement and the H800 SXM5's 50th percentile placement should not be read as a direct comparison, because the H800 SXM5's percentile is not based on any benchmark score. The RTX 5080 SUPER's percentile is based on its 3075-point score. The data supports a simple conclusion: the RTX 5080 SUPER is a verified graphics performer with modest margins over nearby rivals, while the H800 SXM5 is a high-specification compute module whose performance is unmeasured in this database.
