NVIDIA GeForce RTX 5080 SUPER vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded database contains a single benchmark result for the NVIDIA GeForce RTX 5080 SUPER: a 3DMark Steel Nomad DX12 score of 3075. The NVIDIA N1X 48SM has no benchmark entries in the database, so no direct head-to-head comparison can be established from measured scores. The RTX 5080 SUPER sits at the 19th percentile among all GPUs tracked, while the N1X 48SM holds a 50th percentile placement despite having no recorded benchmark data, indicating its classification is based on specifications rather than measured performance.

The RTX 5080 SUPER's nearest rivals provide context for interpreting its score. The Intel Arc Pro B60 leads with an average score of 3182, placing the RTX 5080 SUPER 3.4% behind that part. The NVIDIA Quadro P1000 posts an average of 3163, which puts the RTX 5080 SUPER 2.8% behind. On the other side, the NVIDIA GeForce 820A scores 2983 on average, meaning the RTX 5080 SUPER is 3.1% ahead. The NVIDIA GeForce GTX 860M averages 2967, with the RTX 5080 SUPER leading by 3.6%. These deltas are narrow, clustering within a band of roughly 7 percentage points from the lowest rival to the highest.

Because the N1X 48SM has no benchmark scores, the head-to-head section must rely on architectural specifications rather than measured results. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 compute, while the N1X 48SM provides 28.83 TFLOPS. That is a substantial compute advantage for the RTX 5080 SUPER, roughly double the raw shader throughput. The RTX 5080 SUPER also has 10752 shading units versus 6144 on the N1X 48SM, a 75% higher count. The pixel rate tells a similar story: 293.1 GPixel/s for the RTX 5080 SUPER versus 112.6 GPixel/s for the N1X 48SM. Texture rate is nearly identical, with the RTX 5080 SUPER at 879.3 GTexel/s and the N1X 48SM at 900.9 GTexel/s, a narrow 2.5% difference that favors the integrated part.

Memory bandwidth diverges sharply. The RTX 5080 SUPER uses 24 GB of GDDR7 on a 256-bit bus, achieving 1.02 TB/s. The N1X 48SM pairs 128 GB of LPDDR5X with a 256-bit bus for 273.2 GB/s. The RTX 5080 SUPER's bandwidth is 3.7 times higher. The N1X 48SM compensates with four times the capacity, which suits workloads that need large resident datasets rather than rapid streaming.

Where Each One Wins

The RTX 5080 SUPER wins on compute-heavy workloads. Its FP32 throughput of 56.28 TFLOPS doubles the N1X 48SM's 28.83 TFLOPS. The shading unit count of 10752 versus 6144 gives the discrete card a clear advantage in shader-bound scenarios. The pixel rate of 293.1 GPixel/s versus 112.6 GPixel/s indicates stronger fill-rate performance for rasterization-heavy tasks. The RTX 5080 SUPER also has 84 RT cores versus 48 on the N1X 48SM, and 336 tensor cores versus 192, suggesting better ray tracing and AI acceleration throughput.

The N1X 48SM wins on memory capacity and texture throughput. Its 128 GB of LPDDR5X dwarfs the 24 GB of GDDR7 on the RTX 5080 SUPER. For workloads that require holding large models, massive datasets, or extensive in-memory caches, the N1X 48SM provides far more headroom. The texture rate of 900.9 GTexel/s edges out the RTX 5080 SUPER's 879.3 GTexel/s, a minor but real advantage in texture-bound pipelines. The N1X 48SM also has more TMUs: 384 versus 336, a 14% higher count that supports its texture throughput lead.

Clock behavior differs meaningfully. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost of 2617 MHz. The N1X 48SM starts much lower at 741 MHz but boosts to 2346 MHz. The base-to-boost delta on the N1X 48SM is over 3x, while the RTX 5080 SUPER's boost is only 14% above base. The N1X 48SM's boost clock approaches the RTX 5080 SUPER's base clock but never reaches its boost ceiling.

Power and physical requirements split the two clearly. The RTX 5080 SUPER has a 415 W TDP, uses a dual-slot cooler, requires a 1x 16-pin power connector, and measures 304 mm in length. The N1X 48SM is an IGP with no power connector and no listed TDP. The N1X 48SM's slot width is listed as "IGP," meaning it integrates into a host platform rather than occupying a discrete slot. The RTX 5080 SUPER uses PCIe 5.0 x16, and the N1X 48SM also lists PCIe 5.0 x16 as its bus interface.

The Verdict

The data supports a clear split by use case. The RTX 5080 SUPER is the choice for raw compute, gaming, and bandwidth-sensitive workloads. Its 56.28 TFLOPS FP32, 1.02 TB/s bandwidth, and 293.1 GPixel/s pixel rate dominate the N1X 48SM in every throughput metric except texture rate. The 84 RT cores and 336 tensor cores further position it for ray-traced rendering and AI inference. The 19th percentile ranking among all GPUs, while modest, reflects its position relative to the full database, and its nearest rivals all fall within a narrow 3.6% band, indicating consistent performance near that tier.

The N1X 48SM is the choice for capacity-bound workloads. Its 128 GB of LPDDR5X memory is unmatched by the RTX 5080 SUPER's 24 GB. The 50th percentile placement, despite having no benchmark scores, suggests the database weights its specifications favorably. Its 900.9 GTexel/s texture rate and 384 TMUs give it a slight edge in texture-heavy pipelines. The IGP form factor with no power connector makes it suitable for systems where discrete cooling and power delivery are unavailable.

Benchmark results do not exist for the N1X 48SM, so any performance comparison relies on architectural analysis. The RTX 5080 SUPER's recorded 3DMark Steel Nomad score of 3075 is the only measured data point. Users who need a discrete GPU with proven benchmark performance should select the RTX 5080 SUPER. Users who need maximum memory capacity in an integrated form factor should select the N1X 48SM. The two products serve different segments, and the data does not suggest they compete directly in most scenarios.
