NVIDIA GeForce RTX 5070 SUPER vs NVIDIA N1 16SM Comparison

The Verdict

The recorded data presents an unusual pairing. The NVIDIA GeForce RTX 5070 SUPER is a discrete graphics card with a single recorded benchmark score of 2690 in 3DMark Steel Nomad DX12, placing it at the 18th percentile of all GPUs in the database. The NVIDIA N1 16SM is an integrated graphics processor (IGP) with no recorded benchmark scores at all. The RTX 5070 SUPER has a measurable performance identity; the N1 16SM does not yet have one in this database. For users who need a known quantity for gaming or rendering workloads, the RTX 5070 SUPER is the only option with data to support a decision. The N1 16SM offers a massive 128 GB memory pool and a newer release date, but its lack of benchmark results means its actual performance level remains unquantified.

Architecture Differences

Both processors share the Blackwell 2.0 architecture and are manufactured by TSMC on a 5 nm process node. The RTX 5070 SUPER uses the GB205 chip with a die size of 263 mm² and 31,100 million transistors, yielding a transistor density of 118.3 million per mm². The N1 16SM uses the GB20B chip with a larger die size of 382 mm², though its transistor count is listed as unknown. The N1 16SM belongs to the "Blackwell IGP (N1x)" generation, while the RTX 5070 SUPER is part of the GeForce 50 series. The N1 16SM is an integrated graphics processor with no power connector and an IGP slot width, whereas the RTX 5070 SUPER is a dual-slot discrete card requiring a single 16-pin power connector.

The shading unit counts differ substantially. The RTX 5070 SUPER has 6400 shading units, 200 texture mapping units, and 80 raster operations units. The N1 16SM has 2048 shading units, 128 TMUs, and 24 ROPs. Ray tracing cores number 50 on the RTX 5070 SUPER versus 16 on the N1 16SM. Tensor cores follow the same pattern: 200 on the RTX 5070 SUPER versus 64 on the N1 16SM. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 16SM lists N/A for all three APIs, suggesting it may not be intended for traditional graphics API workloads.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two processors. The only benchmark score available belongs to the RTX 5070 SUPER: 2690 in 3DMark Steel Nomad DX12. This score places it at the 18th percentile among all GPUs in the database. Its nearest rivals in the database are the NVIDIA Quadro K1100M with an average score of 2664 (1% difference), the NVIDIA GeForce GT 1030 with 2662 (1.1% difference), the Intel Arc Pro B50 with 2660 (1.1% difference), and the NVIDIA GeForce GT 440 with 2645 (1.7% difference). The RTX 5070 SUPER leads these rivals by margins ranging from 1% to 1.7%, indicating a narrow performance gap within its benchmark class.

The N1 16SM has no benchmark scores recorded in the database. Its average benchmark score is 0, and its percentile versus all GPUs is listed at 50, though this figure cannot be validated without actual test results. The N1 16SM also has no nearest rivals listed. Consequently, no direct comparison of benchmark performance can be made between the two processors based on the available data. The RTX 5070 SUPER's wins count is 0 and the N1 16SM's wins count is 0, reflecting the absence of head-to-head tests.

Where Each One Wins

The RTX 5070 SUPER wins decisively in every performance category with recorded data. Its FP32 compute of 32.15 TFLOPS is more than three times the N1 16SM's 9.609 TFLOPS. Pixel rate of 201.0 GPixel/s versus 56.30 GPixel/s gives it a 3.6x advantage in fill-rate bound workloads. Texture rate of 502.4 GTexel/s versus 300.3 GTexel/s shows a 1.7x lead in texturing tasks. The RTX 5070 SUPER also has more than three times the shading units (6400 versus 2048), more than three times the ray tracing cores (50 versus 16), and more than three times the tensor cores (200 versus 64). Its memory bandwidth of 672.0 GB/s is 2.5 times the N1 16SM's 273.2 GB/s, which benefits high-resolution textures and data-intensive scenes. The RTX 5070 SUPER's support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 makes it compatible with modern graphics workloads, whereas the N1 16SM lists no API support.

The N1 16SM wins in memory capacity with 128 GB versus 18 GB, a 7.1x advantage in raw storage. It also has a wider memory bus at 256-bit versus 192-bit, and a larger die at 382 mm² versus 263 mm². Its lower base clock of 741 MHz suggests a power-conscious design, though TDP is unknown. The integrated nature of the N1 16SM with no power connector and IGP form factor means it occupies no expansion slot and requires no external power delivery, which could suit compact system designs. The N1 16SM also has a newer release date in 2026 compared to the RTX 5070 SUPER's 2025 launch. However, the absence of benchmark data means the N1 16SM's practical performance cannot be verified. The RTX 5070 SUPER is the only processor in this comparison with proven, recorded benchmark results, and it holds a clear advantage in every measurable performance metric.
