NVIDIA GeForce RTX 5080 Mobile vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the NVIDIA GeForce RTX 5080 Mobile and the NVIDIA N1 16SM. The head-to-head benchmark array is empty, and neither part has a wins count assigned against the other. Consequently, any comparison must rely on the individual benchmark results available for the RTX 5080 Mobile, alongside the architectural and specification data for both products.

The RTX 5080 Mobile holds a percentile score of 81 among all GPUs in the database, while the N1 16SM sits at the 50th percentile. That gap places the two parts in different performance tiers, though the N1 16SM has no benchmark scores recorded at all. Its average benchmark score is listed as 0, and its nearest rivals array is empty, meaning there is no measured data to compare directly.

For the RTX 5080 Mobile, the available benchmark scores are spread across several tests. In 3DMark Steel Nomad DX12, it scores 4952. Geekbench results show 166986 in OpenCL and 169754 in Vulkan. Passmark tests show 27711 in G3D, 12134 in GPU compute, 1095 in G2D, 314 in DirectX 9, 253 in DirectX 11, 171 in DirectX 10, and 116 in DirectX 12. The average benchmark score for the RTX 5080 Mobile is 38349.

The nearest rivals for the RTX 5080 Mobile provide context for its standing. The NVIDIA GeForce MX570 has an average score of 38299, which is 0.1% lower than the RTX 5080 Mobile. The NVIDIA GeForce RTX 4080 Mobile averages 38135, 0.6% lower. The NVIDIA GeForce MX570 A averages 38691, which is 0.9% higher. The AMD Radeon Pro 580X averages 38706, also 0.9% higher. These deltas are small, indicating the RTX 5080 Mobile sits in a tight cluster with those four parts. The RTX 5080 Mobile is effectively at parity with the MX570 and the RTX 4080 Mobile, and marginally behind the MX570 A and the Radeon Pro 580X in average score.

Without any N1 16SM benchmark data, no direct wins can be assigned in either direction. The winsA and winsB counters both read 0. The analysis must therefore focus on what the recorded specifications and the RTX 5080 Mobile's measured performance imply, rather than direct head-to-head results.

Where Each One Wins

The RTX 5080 Mobile clearly wins in raw graphics performance based on the recorded data. Its FP32 throughput is 23.04 TFLOPS, compared to 9.609 TFLOPS for the N1 16SM, a difference of roughly 2.4 times. Texture rate also favors the RTX 5080 Mobile at 360.0 GTexel/s versus 300.3 GTexel/s for the N1 16SM. Pixel rate is 144.0 GPixel/s for the RTX 5080 Mobile versus 56.30 GPixel/s for the N1 16SM, again a substantial margin.

Memory bandwidth heavily favors the RTX 5080 Mobile. It delivers 896.0 GB/s via GDDR7 on a 256-bit bus, while the N1 16SM provides 273.2 GB/s through LPDDR5X also on a 256-bit bus. The RTX 5080 Mobile has 16 GB of memory, while the N1 16SM has 128 GB, but the bandwidth advantage is decisive for graphics workloads.

Shader resources also differ greatly. The RTX 5080 Mobile has 7680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores. The N1 16SM has 2048 shading units, 128 TMUs, 24 ROPs, 16 RT cores, and 64 tensor cores. These numbers indicate the RTX 5080 Mobile is built for high-end rendering and compute, while the N1 16SM appears oriented toward integrated graphics duties with a smaller shader array.

The N1 16SM does win in memory capacity, offering 128 GB versus 16 GB. That is a significant advantage for large datasets or memory-resident workloads, though the lower bandwidth limits its utility for graphics-heavy tasks. The N1 16SM also has a higher boost clock at 2346 MHz versus 1500 MHz for the RTX 5080 Mobile, though the RTX 5080 Mobile has a higher base clock at 975 MHz versus 741 MHz.

For API support, the RTX 5080 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists all APIs as N/A, meaning no DirectX, OpenGL, or Vulkan support is recorded. This makes the RTX 5080 Mobile the clear choice for gaming and graphics applications that rely on those APIs.

Architecture Differences

Both parts use the same Blackwell 2.0 architecture, but they are built on different chips. The RTX 5080 Mobile uses the GB203 chip, while the N1 16SM uses the GB20B chip. Both are fabricated on a 5 nm process at TSMC. The die sizes are close, with the RTX 5080 Mobile at 378 mm² and the N1 16SM at 382 mm². The RTX 5080 Mobile has 45,600 million transistors, while the N1 16SM's transistor count is listed as unknown. The transistor density for the RTX 5080 Mobile is 120.6M per mm², while the N1 16SM has no recorded density.

The memory configurations differ fundamentally. The RTX 5080 Mobile uses 16 GB of GDDR7 with a 256-bit bus and 896.0 GB/s bandwidth. The N1 16SM uses 128 GB of LPDDR5X with a 256-bit bus and 273.2 GB/s bandwidth. The memory clock also differs: the RTX 5080 Mobile runs at 1750 MHz with 28 Gbps effective, while the N1 16SM runs at 1067 MHz with 8.5 Gbps effective.

The RTX 5080 Mobile is a discrete mobile GPU with a TDP of 80 W, whereas the N1 16SM has an unknown TDP. Both are listed as IGP slot width and have no power connectors. The display outputs differ: the RTX 5080 Mobile is listed as "Portable Device Dependent," while the N1 16SM has one HDMI output. Both use PCIe 5.0 x16 as the bus interface.

The generation names differ as well. The RTX 5080 Mobile belongs to the GeForce 50 Mobile generation, with the series labeled GeForce 50-series. The N1 16SM belongs to the Blackwell IGP (N1x) generation, with no series listed. The release dates show the RTX 5080 Mobile released on 2025-04-01, while the N1 16SM is dated 2026-05-31, over a year later.

The Verdict

The data indicates that the RTX 5080 Mobile is a high-performance discrete mobile GPU, while the N1 16SM is an integrated graphics part with a different role. The RTX 5080 Mobile leads in every measured performance metric except memory capacity and boost clock. Its FP32 throughput is 2.4 times higher, its texture rate is 20% higher, and its pixel rate is more than 2.5 times higher. Memory bandwidth is over 3 times higher on the RTX 5080 Mobile.

The N1 16SM offers 128 GB of memory, which is eight times the capacity of the RTX 5080 Mobile, and it has a higher boost clock at 2346 MHz versus 1500 MHz. However, the N1 16SM has no recorded benchmarks, no API support listed, and sits at the 50th percentile with an average score of 0. The RTX 5080 Mobile has a full suite of benchmark results and reaches the 81st percentile.

For workloads that rely on graphics APIs, shader throughput, or memory bandwidth, the RTX 5080 Mobile is clearly the correct choice. For scenarios that require very large memory capacity in an integrated form factor, the N1 16SM has the advantage. The RTX 5080 Mobile is also the only one with a defined TDP at 80 W, while the N1 16SM has an unknown TDP.

The RTX 5080 Mobile's nearest rivals place it in a tight performance band, within 0.9% of the MX570, MX570 A, RTX 4080 Mobile, and Radeon Pro 580X. This suggests the RTX 5080 Mobile is competitive with those parts, though no N1 16SM comparison is possible due to missing data.

Given the absence of any N1 16SM benchmark results, the database cannot confirm its real-world performance. The recorded specifications indicate a lower-end integrated GPU, while the RTX 5080 Mobile is positioned for demanding mobile graphics tasks. The choice between the two depends entirely on whether the user needs the RTX 5080 Mobile's high bandwidth and shader throughput, or the N1 16SM's larger memory pool and integrated form factor. From the data, the RTX 5080 Mobile is the stronger graphics processor.
