NVIDIA GeForce RTX 4080 SUPER vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the NVIDIA GeForce RTX 4080 SUPER against the NVIDIA N1X 48SM. The RTX 4080 SUPER has a complete benchmark suite, while the N1X 48SM has no recorded benchmark scores in the database. This makes a direct numerical comparison impossible for individual workloads.

However, the available aggregate data provides a clear picture. The RTX 4080 SUPER holds an average benchmark score of 54,209 across all recorded tests. The N1X 48SM shows an average score of 0, reflecting the absence of any recorded measurements. The percentile ranking reinforces this gap: the RTX 4080 SUPER sits in the 86th percentile of all GPUs, while the N1X 48SM sits in the 50th percentile. These are not comparable values; the 50th percentile for the N1X 48SM is a default placeholder, not a measured result.

For context, the RTX 4080 SUPER’s nearest rivals in the database are all established discrete GPUs. The NVIDIA GeForce RTX 4080 scores 54,247 on average, a delta of -0.1% versus the SUPER. The AMD Radeon Pro W5700X scores 54,828, a delta of -1.1%. The AMD Radeon RX 6750 GRE 12 GB scores 55,698, a delta of -2.7%. The AMD Radeon 8060S scores 55,757, a delta of -2.8%. The RTX 4080 SUPER trails each of these by a narrow margin, between 0.1% and 2.8%. This indicates that the SUPER model is positioned firmly within the upper tier of discrete graphics cards, with its performance essentially matching or falling slightly behind the nearest alternatives.

The N1X 48SM, by contrast, has no rival data and no measured scores. Any attempt to assign it a performance level would rely on unverified assumptions. The database records it as an active product with a release date in the future, but no benchmark evidence exists to support a comparative statement.

Architecture Differences

The two GPUs come from different architectural generations and are built for entirely different purposes. The RTX 4080 SUPER uses the AD103 chip based on the Ada Lovelace architecture, part of the GeForce 40 series. It is manufactured on a 5 nm process at TSMC, with 45,900 million transistors on a 379 mm² die. The transistor density is 121.1 million per mm².

The N1X 48SM uses the GB20B chip based on the Blackwell 2.0 architecture, listed under the generation name "Blackwell IGP (N1x)". It is also manufactured on a 5 nm process at TSMC, with a die size of 382 mm². The transistor count is listed as unknown, and no transistor density is recorded. The die size difference is small, 3 mm² in favor of the N1X, but the architectural intent differs substantially.

The RTX 4080 SUPER is a discrete add-in board with 10,240 shading units, 320 texture mapping units, 112 raster operation units, 80 ray tracing cores, and 320 tensor cores. It has a base clock of 2295 MHz and a boost clock of 2550 MHz. The N1X 48SM, as an integrated graphics processor, has 6,144 shading units, 384 texture mapping units, 48 raster operation units, 48 ray tracing cores, and 192 tensor cores. Its base clock is 741 MHz, with a boost clock of 2346 MHz. The shading unit count is 40% lower on the N1X, but its texture mapping unit count is 20% higher, indicating a different balance of resources.

Memory configurations diverge sharply. The RTX 4080 SUPER uses 16 GB of GDDR6X memory on a 256-bit bus, achieving 736.3 GB/s of bandwidth with a memory clock of 1438 MHz (23 Gbps effective). The N1X 48SM uses 128 GB of LPDDR5X memory on a 256-bit bus, but bandwidth is only 273.2 GB/s with a memory clock of 1067 MHz (8.5 Gbps effective). The RTX 4080 SUPER delivers 2.7 times the memory bandwidth, while the N1X 48SM provides 8 times the capacity. The bus width is identical at 256 bits, but the memory type and clock rates drive the bandwidth gap.

The RTX 4080 SUPER is a triple-slot card with a 16-pin power connector and a suggested PSU of 700 W, with a TDP of 320 W. The N1X 48SM is an IGP with no power connector and no suggested PSU, and the TDP is listed as unknown. The RTX 4080 SUPER uses PCIe 4.0 x16, while the N1X 48SM uses PCIe 5.0 x16. Display outputs also differ: the RTX 4080 SUPER has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the N1X 48SM has a single HDMI output. The API support is complete for the RTX 4080 SUPER (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), while the N1X 48SM lists N/A for all three APIs.

The production statuses reflect their lifecycles. The RTX 4080 SUPER is end-of-life, with a release date of January 30, 2024, and a successor in the GeForce 50 series. The N1X 48SM is active, with a release date of May 31, 2026, and no predecessor or successor recorded.

The Verdict

The data indicates that these are not competing products in the conventional sense. The RTX 4080 SUPER is a fully measured, high-end discrete GPU with an average benchmark score of 54,209 and a percentile rank of 86. The N1X 48SM has no recorded benchmarks, an average score of 0, and a default percentile of 50. Any user requirement for confirmed performance data would point to the RTX 4080 SUPER, as the database contains no evidence of the N1X 48SM’s capabilities.

From a feature standpoint, the RTX 4080 SUPER offers 52.22 TFLOPS of FP32 performance, a pixel rate of 285.6 GPixel/s, and a texture rate of 816.0 GTexel/s. The N1X 48SM offers 28.83 TFLOPS of FP32, a pixel rate of 112.6 GPixel/s, and a texture rate of 900.9 GTexel/s. The RTX 4080 SUPER leads in raw compute and pixel throughput, while the N1X 48SM leads in texture throughput. The RTX 4080 SUPER also leads in memory bandwidth by a wide margin, which is critical for high-resolution rendering and compute workloads.

The N1X 48SM’s 128 GB of memory is its standout advantage, but without benchmark data, its practical impact on application performance is unverified. The RTX 4080 SUPER’s 16 GB is typical for a high-end discrete card, and the 736.3 GB/s bandwidth is far more suited to gaming and professional rendering tasks.

The verdict is straightforward: the RTX 4080 SUPER is the only product in this comparison with measurable performance data. The N1X 48SM remains an unquantified entity in the database, with no recorded wins, no rival comparisons, and no benchmark scores. For any analysis grounded in recorded facts, the RTX 4080 SUPER is the clear choice based on available evidence.

Where Each One Wins

Based on the recorded data, the RTX 4080 SUPER wins in every measurable performance category. It has a higher FP32 compute rate (52.22 TFLOPS vs 28.83 TFLOPS), a higher pixel rate (285.6 GPixel/s vs 112.6 GPixel/s), and a higher memory bandwidth (736.3 GB/s vs 273.2 GB/s). It also has more shading units (10,240 vs 6,144), more ROPs (112 vs 48), more RT cores (80 vs 48), and more tensor cores (320 vs 192). The boost clock is higher as well (2550 MHz vs 2346 MHz).

The N1X 48SM holds advantages in a few specific specification areas. It has a larger memory capacity (128 GB vs 16 GB), a higher texture rate (900.9 GTexel/s vs 816.0 GTexel/s), more TMUs (384 vs 320), and a newer PCIe interface (5.0 x16 vs 4.0 x16). It is also an IGP with no power connector, making it suitable for integrated configurations, while the RTX 4080 SUPER requires a triple-slot board with a 16-pin connector and a 700 W suggested PSU.

For gaming and high-bandwidth rendering workloads, the RTX 4080 SUPER is the only product with evidence of capability. Its 86th percentile ranking and complete API support indicate a fully functional discrete GPU. For applications that require massive memory capacity, the N1X 48SM’s 128 GB is unique, but the lack of benchmark scores means no performance validation exists. The RTX 4080 SUPER’s 16 GB is far smaller, but its 736.3 GB/s bandwidth makes it the superior choice for data-intensive tasks that are sensitive to memory throughput.

The texture rate advantage of the N1X 48SM (900.9 GTexel/s vs 816.0 GTexel/s) suggests it may have an edge in texture-heavy workloads, but this is not confirmed by any benchmark measurements. The RTX 4080 SUPER’s higher pixel rate and compute throughput point to stronger overall rasterization and compute performance. Without recorded data for the N1X 48SM, the RTX 4080 SUPER is the only product with demonstrated wins in the database.
