Architecture Differences

The two GPUs come from different architecture families. The RTX 4070 SUPER is based on the AD104 chip using the Ada Lovelace architecture, while the N1 16SM uses the GB20B chip on Blackwell 2.0. Both are manufactured on a 5 nm process by TSMC, but the die sizes differ: the RTX 4070 SUPER measures 294 mm², while the N1 16SM measures 382 mm². The RTX 4070 SUPER packs 35,800 million transistors with a density of 121.8M per mm², whereas the N1 16SM has an unknown transistor count.

The N1 16SM is categorized as an integrated graphics processor, which is reflected in its slot width of IGP, no power connectors, and a single HDMI display output. The RTX 4070 SUPER is a dual-slot discrete card with one 16-pin power connector, a suggested PSU of 550 W, and multiple display outputs including one HDMI 2.1 and three DisplayPort 1.4a ports.

Clock behavior differs significantly. The RTX 4070 SUPER has a base clock of 1980 MHz and a boost clock of 2475 MHz. The N1 16SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, which is close to the RTX 4070 SUPER's boost. Memory clocks also diverge: the RTX 4070 SUPER runs its GDDR6X at 1313 MHz (21 Gbps effective), while the N1 16SM runs LPDDR5X at 1067 MHz (8.5 Gbps effective).

API support sets them apart. The RTX 4070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM has no DirectX, OpenGL, or Vulkan support recorded in the database, marked as N/A. This makes the N1 16SM unsuitable for standard gaming workloads that rely on these graphics APIs.

Pixel and texture rates show the throughput gap. The RTX 4070 SUPER achieves 198.0 GPixel/s and 554.4 GTexel/s, while the N1 16SM achieves 56.30 GPixel/s and 300.3 GTexel/s. The RTX 4070 SUPER is roughly 3.5 times faster in pixel rate and about 1.8 times faster in texture rate.

The Verdict

The data indicates a clear performance hierarchy. The RTX 4070 SUPER holds an 83rd percentile ranking among all GPUs and an average benchmark score of 43223, while the N1 16SM sits at the 50th percentile with an average benchmark score of zero due to no recorded benchmarks. The RTX 4070 SUPER has ten benchmark entries across DirectX, OpenCL, Vulkan, and compute tests. The N1 16SM has zero benchmark entries, making its benchmark performance undocumented in the database.

The RTX 4070 SUPER is a gaming and compute-oriented discrete GPU with mature API support, high memory bandwidth, and high FP32 throughput. The N1 16SM is an active IGP with a large 128 GB memory pool but low bandwidth and limited compute resources. For any workload that requires standard graphics APIs, DirectX 12, Vulkan, or OpenGL, the RTX 4070 SUPER is the only option with recorded support. For applications that need massive memory capacity in a single package, the N1 16SM offers 128 GB, but it lacks the bandwidth and compute throughput to feed that capacity effectively.

The RTX 4070 SUPER is end-of-life, while the N1 16SM is active, but production status does not change the measured capability gap. The nearest rivals to the RTX 4070 SUPER in average score are the NVIDIA Quadro M6000 24 GB at 43262 (0.1% higher), the GeForce RTX 5050 Mobile at 43268 (0.1% higher), the Quadro M6000 at 43301 (0.2% higher), and the RTX 4090 Mobile at 43667 (1% higher). The RTX 4070 SUPER sits within 1% of these four GPUs, indicating its score is tightly clustered with that performance tier.

Where Each One Wins

The RTX 4070 SUPER wins in every measured category where data exists. Its FP32 throughput of 35.48 TFLOPS dominates the N1 16SM's 9.609 TFLOPS. The pixel rate advantage is substantial: 198.0 GPixel/s versus 56.30 GPixel/s. Texture rate is also higher at 554.4 GTexel/s versus 300.3 GTexel/s. Memory bandwidth favors the RTX 4070 SUPER at 504.2 GB/s versus 273.2 GB/s, despite the N1 16SM having a wider 256-bit bus. The RTX 4070 SUPER's 12 GB of GDDR6X provides faster access than the N1 16SM's 128 GB of LPDDR5X.

For gaming and traditional graphics workloads, the RTX 4070 SUPER is the only option with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. It also has more shading units, TMUs, ROPs, RT cores, and tensor cores. The N1 16SM has no API support recorded, which prevents it from running standard graphics applications.

The N1 16SM wins on memory capacity, offering 128 GB compared to 12 GB. It also has a newer PCIe 5.0 x16 interface versus PCIe 4.0 x16, a larger die size at 382 mm², and an active production status. Its boost clock of 2346 MHz is close to the RTX 4070 SUPER's 2475 MHz, but the base clock is far lower at 741 MHz.

The RTX 4070 SUPER is suited for high-throughput rendering, compute, and gaming tasks that rely on mature APIs and high bandwidth. The N1 16SM is positioned for scenarios requiring very large memory capacity in an integrated form factor, but its low bandwidth and compute rates limit its applicability. The recorded data shows no benchmark wins for the N1 16SM, as it has no scores to compare. For any workload that can use the RTX 4070 SUPER's API set, the performance gap is decisive.
