NVIDIA GeForce RTX 5080 Mobile vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 5080 Mobile and the NVIDIA N1 20SM. The head-to-head benchmark array is empty, and neither part has recorded wins in matched tests. This means the two cannot be compared through identical workloads in the current dataset.

However, the RTX 5080 Mobile has a substantial set of individual benchmark results. Its average benchmark score across all recorded tests is 38349, placing it at the 81st percentile of all GPUs in the database. The N1 20SM has no recorded benchmark scores, an average score of 0, and sits at the 50th percentile based on its placement among all GPUs. The absence of test data for the N1 20SM means any direct numeric comparison must rely on the RTX 5080 Mobile's standalone performance figures.

The RTX 5080 Mobile's nearest rivals in the database provide context for its performance level. It scores 0.1% above the NVIDIA GeForce MX570, which has an average score of 38299. It is 0.6% ahead of the NVIDIA GeForce RTX 4080 Mobile, which averages 38135. The RTX 5080 Mobile trails the NVIDIA GeForce MX570 A by 0.9% (that part averages 38691) and the AMD Radeon Pro 580X by 0.9% (that part averages 38706). These delta values are all within one percentage point, indicating that the RTX 5080 Mobile's average performance is tightly clustered with these four parts.

Looking at the RTX 5080 Mobile's individual benchmark scores, the strongest results appear in compute and API-specific tests. In Geekbench Vulkan, it scores 169754, while in Geekbench OpenCL it scores 166986. The PassMark G3D test yields a score of 27711, and the PassMark GPU Compute test produces 12134. In 3DMark Steel Nomad DX12, the score is 4952. Older DirectX tests show lower numbers: PassMark DirectX 11 scores 253, PassMark DirectX 10 scores 171, and PassMark DirectX 12 scores 116. The PassMark G2D test returns 1095, and PassMark DirectX 9 scores 314.

The N1 20SM has no equivalent results in the database. Its percentile placement at 50% suggests it is positioned in the middle of the GPU distribution, but without benchmark scores, the recorded data cannot confirm where its actual performance lands. The RTX 5080 Mobile's 81st percentile ranking places it clearly above the median, with an average score nearly 31 times higher than the N1 20SM's recorded average of 0.

The Verdict

The data supports a clear choice for users who need proven, measured performance: the NVIDIA GeForce RTX 5080 Mobile. It has ten recorded benchmark results across compute, graphics, and API-specific tests, an average score of 38349, and an 81st percentile ranking. The N1 20SM has no benchmark results at all, so there is no measured evidence of its performance in the database.

The RTX 5080 Mobile uses the GB203 chip with 7680 shading units, 240 texture mapping units, and 96 raster output units. It delivers 23.04 TFLOPS of FP32 performance and 23.04 TFLOPS of FP16 performance. Its memory subsystem uses 16 GB of GDDR7 on a 256-bit bus, achieving 896.0 GB/s of bandwidth. The pixel rate is 144.0 GPixel/s, and the texture rate is 360.0 GTexel/s. These specifications are all recorded and verifiable.

The N1 20SM uses the GB20B chip with 2560 shading units, 160 texture mapping units, and 24 raster output units. It delivers 12.01 TFLOPS of FP32 and 12.01 TFLOPS of FP16. Its memory is 128 GB of LPDDR5X on a 256-bit bus, with 273.2 GB/s of bandwidth. The pixel rate is 56.30 GPixel/s, and the texture rate is 375.4 GTexel/s. While these specifications are recorded, no benchmark scores exist to confirm real-world behavior.

For a buyer who requires validated performance data, the RTX 5080 Mobile is the only part with measurements. For a user who prioritizes memory capacity and is willing to accept unverified performance, the N1 20SM offers 128 GB of memory versus 16 GB. The RTX 5080 Mobile has 3 times the shading units, 1.5 times the texture units, 4 times the raster units, and roughly double the FP32 throughput. Its memory bandwidth is 3.3 times higher. The N1 20SM has 8 times the memory capacity.

Where Each One Wins

The RTX 5080 Mobile wins in every category where the database has recorded measurements. Its benchmark scores cover DirectX 9, 10, 11, and 12, OpenCL, Vulkan, and 3DMark Steel Nomad. The N1 20SM has no wins because it has no benchmark entries.

In compute workloads, the RTX 5080 Mobile's Geekbench OpenCL score of 166986 and Vulkan score of 169754 indicate strong parallel processing capability. Its PassMark GPU Compute score of 12134 further supports this. The N1 20SM's FP32 throughput of 12.01 TFLOPS is approximately half of the RTX 5080 Mobile's 23.04 TFLOPS, but without benchmark data, the practical effect of this difference cannot be quantified.

In graphics rendering, the RTX 5080 Mobile's PassMark G3D score of 27711 is the highest among its PassMark graphics tests. Its 3DMark Steel Nomad DX12 score of 4952 provides a modern DirectX 12 workload result. The N1 20SM reports DirectX as N/A, OpenGL as N/A, and Vulkan as N/A, meaning it does not expose these APIs in the recorded specifications. This makes the RTX 5080 Mobile the only part with confirmed API support for modern graphics workloads.

For memory-intensive tasks, the N1 20SM's 128 GB of LPDDR5X is a significant capacity advantage. However, its bandwidth of 273.2 GB/s is lower than the RTX 5080 Mobile's 896.0 GB/s. The RTX 5080 Mobile also uses GDDR7 memory, which is a newer type than LPDDR5X. The N1 20SM's higher capacity could benefit workloads that need large working sets, but the RTX 5080 Mobile's higher bandwidth benefits throughput-sensitive tasks.
