NVIDIA GeForce RTX 4080 SUPER vs NVIDIA N1 16SM Comparison

The NVIDIA GeForce RTX 4080 SUPER and the NVIDIA N1 16SM represent two distinctly different products from the same manufacturer, yet they share a surprising number of underlying technologies. The RTX 4080 SUPER is a dedicated add-in board from the GeForce 40-series, built on the Ada Lovelace architecture with the AD103 chip. The N1 16SM is an integrated graphics processor from the Blackwell IGP (N1x) generation, using the GB20B chip and Blackwell 2.0 architecture. Both are fabricated on a 5 nm process at TSMC, which gives them a common manufacturing foundation, but their design goals diverge sharply. The RTX 4080 SUPER targets high-end desktop gaming and professional workloads, while the N1 16SM appears tailored for integrated system scenarios where power delivery and physical footprint are constrained.

Where Each One Wins

The performance split between these two parts is not close. The recorded benchmark data shows that the RTX 4080 SUPER has an average benchmark score of 54,209, while the N1 16SM has no recorded benchmarks and an average score of zero. The RTX 4080 SUPER also holds an 86th percentile position among all GPUs in the database, whereas the N1 16SM sits at the 50th percentile. This gap means the RTX 4080 SUPER wins every measurable benchmark category, from DirectX 12 to OpenCL to compute tasks.

The RTX 4080 SUPER wins in raw shading throughput. Its FP32 compute reaches 52.22 TFLOPS, compared to 9.609 TFLOPS for the N1 16SM. That is a fivefold advantage in floating-point operations. The RTX 4080 SUPER also delivers 816.0 GTexel/s of texture fill rate versus 300.3 GTexel/s for the N1 16SM, and 285.6 GPixel/s of pixel rate versus 56.30 GPixel/s. These numbers indicate that the RTX 4080 SUPER is designed for sustained heavy rendering, while the N1 16SM is a lighter-duty part.

Memory capacity is where the N1 16SM takes a clear lead. The N1 16SM offers 128 GB of LPDDR5X memory on a 256-bit bus, while the RTX 4080 SUPER provides 16 GB of GDDR6X on the same 256-bit bus width. The N1 16SM has eight times the memory capacity. However, bandwidth tells a different story. The RTX 4080 SUPER reaches 736.3 GB/s, while the N1 16SM achieves 273.2 GB/s. The RTX 4080 SUPER has roughly 2.7 times the memory bandwidth despite having far less total memory. This suggests the N1 16SM is intended for workloads that require large memory pools, such as certain AI inference or data processing tasks, rather than high-frequency rendering.

Architecture Differences

The two chips share a 5 nm TSMC process, but their internal structures differ substantially. The RTX 4080 SUPER uses the AD103 die, which measures 379 mm² and packs 45,900 million transistors, resulting in a transistor density of 121.1 million per square millimeter. The N1 16SM uses the GB20B die, which is slightly larger at 382 mm², though its transistor count is listed as unknown and its density is not recorded.

Shading unit counts reveal the performance hierarchy. The RTX 4080 SUPER has 10,240 shading units, 320 texture mapping units, and 112 raster operation pipelines. The N1 16SM has only 2,048 shading units, 128 TMUs, and 24 ROPs. The RTX 4080 SUPER also carries 80 ray tracing cores and 320 tensor cores, while the N1 16SM includes 16 ray tracing cores and 64 tensor cores. The RTX 4080 SUPER has five times the shading units, 2.5 times the TMUs, and over four times the ROPs compared to the N1 16SM.

Clock speeds also differ. The RTX 4080 SUPER has a base clock of 2295 MHz and a boost clock of 2550 MHz. The N1 16SM runs at a base clock of 741 MHz and a boost of 2346 MHz. The RTX 4080 SUPER starts at a much higher base frequency, and its boost clock is slightly higher as well. The memory clocks follow a similar pattern: the RTX 4080 SUPER uses a 1438 MHz memory clock with 23 Gbps effective data rate, while the N1 16SM uses a 1067 MHz clock with 8.5 Gbps effective.

The power delivery and physical design are starkly different. The RTX 4080 SUPER has a TDP of 320 W, uses a triple-slot cooler, requires a 16-pin power connector, and lists a suggested power supply of 700 W. The N1 16SM has an unknown TDP, is classified as an IGP (integrated graphics processor), uses no power connectors, and does not list a suggested PSU. The RTX 4080 SUPER measures 310 mm in length, 140 mm in height, and 61 mm in width. The N1 16SM has no recorded dimensions, consistent with an integrated part that does not occupy expansion slots.

The bus interfaces also differ. The RTX 4080 SUPER uses PCIe 4.0 x16, while the N1 16SM uses PCIe 5.0 x16. The N1 16SM supports the newer bus standard, which may offer higher transfer rates for system memory access, though the recorded data does not provide specific bandwidth figures for this interface. The RTX 4080 SUPER provides three DisplayPort 1.4a outputs and one HDMI 2.1 output. The N1 16SM lists only a single HDMI output.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, meaning there are no directly matched test runs for these two products. However, the individual benchmark scores for the RTX 4080 SUPER can be compared against the N1 16SM’s lack of recorded data. The RTX 4080 SUPER achieves 6,600 in 3DMark Steel Nomad DX12, 219,065 in Geekbench OpenCL, and 260,075 in Geekbench Vulkan. In Passmark tests, it scores 193 in DirectX 10, 301 in DirectX 11, 134 in DirectX 12, 381 in DirectX 9, 1,270 in G2D, 34,245 in G3D, and 19,822 in GPU compute.

The N1 16SM has none of these scores recorded. Its average benchmark score is zero, and it has no nearest rivals listed. This absence of data means that any direct numerical comparison must rely on the architectural specifications and the RTX 4080 SUPER’s own benchmark results. The RTX 4080 SUPER’s nearest rivals, according to the database, are the NVIDIA GeForce RTX 4080 with an average score of 54,247, the AMD Radeon Pro W5700X at 54,828, the AMD Radeon RX 6750 GRE 12 GB at 55,698, and the AMD Radeon 8060S at 55,757. The RTX 4080 SUPER trails each of these by small margins: 0.1 percent behind the RTX 4080, 1.1 percent behind the W5700X, 2.7 percent behind the RX 6750 GRE, and 2.8 percent behind the Radeon 8060S.

These deltas are minor, all within three percent, indicating that the RTX 4080 SUPER is competitive with its immediate peers. The N1 16SM does not appear in any rival comparison because it has no benchmark scores to rank. Its percentile placement at 50 suggests it sits at the median of all GPUs, but that is based on its production status and specifications rather than measured performance.
