NVIDIA GeForce RTX 5070 SUPER vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded benchmark data for these two parts is asymmetrical. The NVIDIA GeForce RTX 5070 SUPER has a single published benchmark result, while the NVIDIA N1X 48SM has no recorded benchmark scores in the database. The RTX 5070 SUPER scores 2690 points in the 3DMark Steel Nomad DX12 test. This places it in the 18th percentile among all GPUs in the database, a modest standing that reflects its position relative to a broad field.

The nearest rivals for the RTX 5070 SUPER provide useful context. The NVIDIA Quadro K1100M averages 2664 points, putting the RTX 5070 SUPER 1% ahead. The NVIDIA GeForce GT 1030 averages 2662 points, with the RTX 5070 SUPER leading by 1.1%. The Intel Arc Pro B50 also averages 2660 points, again a 1.1% advantage for the RTX 5070 SUPER. The NVIDIA GeForce GT 440 averages 2645 points, and the RTX 5070 SUPER holds a 1.7% edge. These deltas are narrow, meaning the RTX 5070 SUPER sits in a tightly contested cluster rather than dominating its immediate competitors.

The N1X 48SM has no benchmark entries, no average score, and no nearest rivals listed. Its percentile standing of 50 is a database artifact tied to the empty benchmark array, not a measured performance level. Direct head-to-head comparisons between the two cards are therefore impossible from the recorded data. The only quantitative comparison available is architectural, which the following sections address.

Architecture Differences

Both parts share the Blackwell 2.0 architecture and are fabricated by TSMC on a 5 nm process. The RTX 5070 SUPER uses the GB205 chip, while the N1X 48SM uses the GB20B chip. The transistor counts diverge sharply. The RTX 5070 SUPER integrates 31,100 million transistors on a 263 mm² die, yielding a transistor density of 118.3M per mm². The N1X 48SM has an unknown transistor count but a larger die at 382 mm², with no density figure recorded.

The RTX 5070 SUPER is a discrete add-in board from the GeForce 50-series. The N1X 48SM belongs to the Blackwell IGP (N1x) generation, meaning it is an integrated graphics processor rather than a standalone card. This distinction drives many other differences. The RTX 5070 SUPER carries 6400 shading units, 200 texture mapping units, and 80 raster operation units. The N1X 48SM has 6144 shading units, 384 TMUs, and 48 ROPs. The N1X 48SM has nearly double the TMU count, which explains its higher texture rate despite fewer shading units.

Ray tracing and tensor core counts also differ. The RTX 5070 SUPER has 50 RT cores and 200 tensor cores. The N1X 48SM has 48 RT cores and 192 tensor cores. These are close totals, reflecting the similar architectural generation. Clock speeds show a larger gap. The RTX 5070 SUPER runs at a 2325 MHz base and 2512 MHz boost. The N1X 48SM has a 741 MHz base and a 2346 MHz boost. The N1X 48SM's base clock is far lower, but its boost clock approaches the RTX 5070 SUPER's level.

Memory configurations differ substantially. The RTX 5070 SUPER uses 18 GB of GDDR7 on a 192-bit bus, achieving 672.0 GB/s bandwidth. Memory runs at 1750 MHz with 28 Gbps effective speed. The N1X 48SM uses 128 GB of LPDDR5X on a 256-bit bus, but bandwidth is only 273.2 GB/s. Its memory clock is 1067 MHz with 8.5 Gbps effective speed. The RTX 5070 SUPER has a narrower bus but much faster memory, resulting in more than double the bandwidth.

Process node and foundry are identical, but physical implementation differs. The RTX 5070 SUPER is a dual-slot card with a 245 mm length, 115 mm height, and 40 mm width. It uses a single 16-pin power connector and has a 275 W TDP. The N1X 48SM is an IGP with no slot width, no power connectors, and an unknown TDP. Its dimensions are not recorded. The RTX 5070 SUPER offers 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs. The N1X 48SM has only 1x HDMI.

API support also diverges. The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists DirectX, OpenGL, and Vulkan as N/A. Both use a PCIe 5.0 x16 bus interface. Production status is Active for both, with the RTX 5070 SUPER released at the end of 2025 and the N1X 48SM in mid-2026.

Where Each One Wins

The RTX 5070 SUPER wins decisively in raw compute throughput. Its FP32 rating is 32.15 TFLOPS, and FP16 matches at 32.15 TFLOPS with a 1:1 ratio. The N1X 48SM delivers 28.83 TFLOPS in both FP32 and FP16, again at 1:1. The RTX 5070 SUPER holds a 3.32 TFLOPS advantage in each precision class, approximately 11.5% higher. Pixel rate favors the RTX 5070 SUPER at 201.0 GPixel/s versus 112.6 GPixel/s for the N1X 48SM. Texture rate reverses the order: the N1X 48SM achieves 900.9 GTexel/s, while the RTX 5070 SUPER manages 502.4 GTexel/s. The N1X 48SM's 384 TMUs drive this win despite its lower clock.

Memory bandwidth belongs to the RTX 5070 SUPER at 672.0 GB/s, more than double the N1X 48SM's 273.2 GB/s. However, the N1X 48SM has vastly more memory capacity at 128 GB versus 18 GB. That capacity advantage matters for large datasets or integrated memory pools, but the bandwidth deficit limits sustained throughput. The RTX 5070 SUPER's GDDR7 memory with 28 Gbps effective speed is a significant speedup over the N1X 48SM's 8.5 Gbps LPDDR5X.

The N1X 48SM wins on texture throughput and memory capacity. Its 900.9 GTexel/s texture rate is 79.3% higher than the RTX 5070 SUPER. The 128 GB memory pool is over seven times larger. These traits suit workloads that are texture-heavy or require holding large working sets locally. The RTX 5070 SUPER wins on compute, pixel fill, memory bandwidth, and software API support. For gaming or general graphics workloads that rely on DirectX or Vulkan, the RTX 5070 SUPER is the functional choice. The N1X 48SM's N/A API status means it lacks the standard graphics interfaces.
