NVIDIA GeForce RTX 5070 SUPER vs NVIDIA N1 20SM Comparison

Where Each One Wins

The recorded data splits these two NVIDIA parts into entirely different roles. The GeForce RTX 5070 SUPER is a discrete graphics card built for rendering workloads, with a single 3DMark Steel Nomad DX12 score of 2690. The N1 20SM is an integrated graphics processor (IGP) with no benchmark entries in the database, meaning its avgBenchmarkScore is 0. The RTX 5070 SUPER therefore holds every measurable performance win by default; the N1 20SM has zero recorded wins.

The use-case split is stark. The RTX 5070 SUPER sits in the 18th percentile among all GPUs, which places it below the majority of the database's tested cards, yet it still outperforms its nearest listed rivals by a small margin. The N1 20SM sits in the 50th percentile, but that figure is derived from an empty benchmark list, so it reflects no actual workload results. For any task that relies on a 3D graphics benchmark, the RTX 5070 SUPER is the only part with demonstrable capability.

The N1 20SM does win on integration and memory capacity. It packs 128 GB of LPDDR5X memory, which is far beyond the 18 GB GDDR7 on the RTX 5070 SUPER. The N1 20SM is an IGP with no power connector and a slot width of "IGP," indicating it is meant to be embedded into a system rather than installed as an expansion card. The RTX 5070 SUPER uses a dual-slot cooler and a 16-pin power connector, making it a standalone add-in board.

For gaming, rendering, or any DirectX/Vulkan workload, the RTX 5070 SUPER is the clear choice because the N1 20SM lists its DirectX, OpenGL, and Vulkan support as "N/A." The N1 20SM is better suited for scenarios where massive memory capacity and low integration complexity matter more than raw 3D throughput. The data supports only one conclusion: the RTX 5070 SUPER wins every tested benchmark, while the N1 20SM wins on memory size and form factor.

Architecture Differences

Both parts use the same Blackwell 2.0 architecture and are fabricated on a 5 nm process at TSMC. The silicon differs: the RTX 5070 SUPER uses the GB205 chip, while the N1 20SM uses the GB20B chip. The RTX 5070 SUPER carries 31,100 million transistors on a 263 mm² die, giving a transistor density of 118.3M / mm². The N1 20SM has an unknown transistor count but a larger die at 382 mm², which suggests a different design priority: more memory interface and I/O, less raw compute.

The compute resources are heavily skewed toward the discrete card. The RTX 5070 SUPER has 6400 shading units, 200 texture mapping units, 80 ROPs, 50 RT cores, and 200 tensor cores. The N1 20SM has 2560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. That is a 2.5x difference in shading units, a 2.5x difference in RT cores, and a 2.5x difference in tensor cores. The N1 20SM's texture rate of 375.4 GTexel/s is 74.7% of the RTX 5070 SUPER's 502.4 GTexel/s, but its pixel rate of 56.30 GPixel/s is only 28.0% of the 201.0 GPixel/s on the discrete card.

Clock behavior also differs. The RTX 5070 SUPER has a base clock of 2325 MHz and a boost clock of 2512 MHz. The N1 20SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, which is close to the RTX 5070 SUPER's base. The N1 20SM's boost clock is 6.6% lower than the RTX 5070 SUPER's boost clock, but its base clock is 68.1% lower, indicating a wider dynamic range for power management.

Memory architecture is a major divergence. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, yielding 672.0 GB/s of bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus, yielding 273.2 GB/s. The RTX 5070 SUPER has 2.46x the memory bandwidth, but the N1 20SM has 7.11x the memory capacity. The memory clocks also differ: 1750 MHz (28 Gbps effective) for GDDR7 versus 1067 MHz (8.5 Gbps effective) for LPDDR5X.

The feature set diverges on API support. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists all three as "N/A." Both use PCIe 5.0 x16, but the N1 20SM's IGP form factor means it likely does not occupy a physical slot in the same way.

Head-to-Head Benchmarks

The database contains no shared benchmark results between these two parts. The RTX 5070 SUPER has one entry: 3DMark Steel Nomad DX12 with a score of 2690. The N1 20SM has an empty benchmark array, so there is no score to compare directly.

What the data does show is the RTX 5070 SUPER's position against its nearest rivals. It leads the NVIDIA Quadro K1100M by 1.0% (2664 vs 2690), the GeForce GT 1030 by 1.1% (2662 vs 2690), the Intel Arc Pro B50 by 1.1% (2660 vs 2690), and the GeForce GT 440 by 1.7% (2645 vs 2690). These are narrow margins, all under 2%, so the RTX 5070 SUPER is only marginally faster than those older or lower-tier parts in this specific test.

The percentile ranking of 18 for the RTX 5070 SUPER means it falls below 82% of all GPUs in the database. That is a low overall standing, but it still outranks its immediate neighbors. The N1 20SM's 50th percentile is misleading because it has no benchmark data; the percentile is assigned by the database as a default, not by measured performance.

For the N1 20SM, the only quantitative facts are its compute rates: 12.01 TFLOPS FP32 and FP16. The RTX 5070 SUPER delivers 32.15 TFLOPS for both FP32 and FP16. That is a 2.68x advantage for the discrete card in raw floating-point throughput. In texture rate, the RTX 5070 SUPER leads 502.4 GTexel/s to 375.4 GTexel/s, a 33.8% gap. In pixel rate, the lead is 201.0 GPixel/s to 56.30 GPixel/s, a 3.57x gap.

The memory bandwidth comparison is similarly one-sided: 672.0 GB/s versus 273.2 GB/s, a 2.46x advantage for the RTX 5070 SUPER. The N1 20SM's only numerical win is capacity, with 128 GB versus 18 GB. The boost clock gap is small: 2512 MHz versus 2346 MHz, only 7.1% apart. The base clock gap is enormous: 2325 MHz versus 741 MHz, a 3.14x difference.

The Verdict

The data points to two different buyers. The RTX 5070 SUPER is the only part with a recorded benchmark score: 2690 in 3DMark Steel Nomad DX12. That score places it in the 18th percentile of all GPUs, and it narrowly edges its nearest rivals by 1.0% to 1.7%. For anyone running DirectX 12, Vulkan, or OpenGL workloads, the RTX 5070 SUPER is the functional choice because the N1 20SM has no API support listed. Its 32.15 TFLOPS FP32, 672.0 GB/s memory bandwidth, and 50 RT cores give it a clear compute advantage over the N1 20SM's 12.01 TFLOPS, 273.2 GB/s, and 20 RT cores.

The N1 20SM is a different class of product. With 128 GB of LPDDR5X memory, a 256-bit bus, and no power connector, it is designed for system integration where memory capacity and low power footprint matter more than 3D rendering. Its 50th percentile ranking is not backed by any benchmark results, so it cannot be compared to the RTX 5070 SUPER on performance. The N1 20SM also lacks DirectX, OpenGL, and Vulkan support, which makes it unsuitable for standard graphics APIs.

The verdict is straightforward: the RTX 5070 SUPER wins every measurable performance metric and is the only part with valid benchmark data. The N1 20SM wins on memory capacity and integration simplicity, but it has no recorded graphics performance. Choose the RTX 5070 SUPER for any rendering task; choose the N1 20SM only if the requirement is a large unified memory pool in an IGP form factor. The database contains no head-to-head benchmark results, so any direct performance comparison beyond the specifications above is unsupported.
