NVIDIA GeForce RTX 4080 SUPER vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data contains benchmark scores for the NVIDIA GeForce RTX 4080 SUPER, while the NVIDIA N1X 40SM has no benchmark entries in the database. This absence of recorded measurements for the N1X 40SM means the head-to-head comparison relies entirely on the RTX 4080 SUPER’s absolute performance and the relative positioning provided by its nearest rivals.

The RTX 4080 SUPER delivers an average benchmark score of 54,209 across all tests. Its percentile ranking sits at 86, indicating it outperforms the vast majority of GPUs in the database. In 3DMark Steel Nomad (DX12), the card records a score of 6,600. Geekbench OpenCL returns 219,065 points, while Geekbench Vulkan reaches 260,075 points. Passmark results show a G3D score of 34,245, a GPU compute score of 19,822, and DirectX 11 performance at 301 points. DirectX 12 yields 134 points, DirectX 10 produces 193 points, and DirectX 9 reaches 381 points. Passmark G2D scores 1,270.

The nearest rivals in the database provide context for the RTX 4080 SUPER’s standing. The NVIDIA GeForce RTX 4080 posts an average score of 54,247, which puts it 0.1% ahead of the RTX 4080 SUPER. The AMD Radeon Pro W5700X averages 54,828, a 1.1% advantage over the RTX 4080 SUPER. The AMD Radeon RX 6750 GRE 12 GB averages 55,698, exceeding the RTX 4080 SUPER by 2.7%. The AMD Radeon 8060S averages 55,757, leading by 2.8%. These deltas are narrow, indicating the RTX 4080 SUPER sits in a tightly contested performance band where no rival holds a commanding margin.

The N1X 40SM, by contrast, has an average benchmark score of 0 and no nearest rival entries. Its percentile rank is 50, which places it at the median of all GPUs in the database, but this figure derives from a lack of measured data rather than demonstrated performance. Without any benchmark scores, the database cannot confirm how the N1X 40SM would fare against the RTX 4080 SUPER in any specific workload.

Where Each One Wins

The RTX 4080 SUPER’s recorded wins are comprehensive across every benchmark category in the database. Its strongest absolute results appear in Geekbench Vulkan (260,075) and Geekbench OpenCL (219,065), indicating robust general-purpose compute performance. In Passmark G3D, the 34,245 score reflects solid rasterization throughput. The GPU compute score of 19,822 further supports compute-heavy workloads. DirectX 11 at 301 points and DirectX 9 at 381 points show strong legacy API support, while DirectX 12 at 134 points and DirectX 10 at 193 points are lower but still functional.

The N1X 40SM has no wins in any benchmark category because no scores are recorded. The database shows zero entries for its benchmarks, so there is no evidence of advantage in any test. Its percentile rank of 50 is a placeholder derived from absence of data, not a measured outcome. The RTX 4080 SUPER therefore wins every benchmark category by default, simply because it has measurable results and the N1X 40SM does not.

The use-case split from the data is straightforward. The RTX 4080 SUPER delivers verified performance in DX12, Vulkan, OpenCL, and compute workloads. The N1X 40SM cannot be assigned any workload advantage based on recorded measurements. For any application requiring a discrete GPU with proven throughput, the RTX 4080 SUPER is the only option with database-backed evidence.

Architecture Differences

The RTX 4080 SUPER uses the AD103 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It contains 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1 million per mm². The N1X 40SM uses the GB20B chip on the Blackwell 2.0 architecture, also fabricated by TSMC on a 5 nm process. Its die measures 382 mm², slightly larger than the RTX 4080 SUPER, but its transistor count is listed as unknown, so density cannot be computed.

The RTX 4080 SUPER has 10,240 shading units, 320 texture mapping units, 112 ROPs, 80 RT cores, and 320 tensor cores. The N1X 40SM has 5,120 shading units, exactly half the RTX 4080 SUPER’s count. Its TMUs match at 320, but ROPs drop to 40, RT cores drop to 40, and tensor cores drop to 160. The RTX 4080 SUPER therefore holds a 2:1 advantage in shading units, RT cores, and tensor cores, while the N1X 40SM matches TMU count and has fewer ROPs.

Pixel rate for the RTX 4080 SUPER is 285.6 GPixel/s, while the N1X 40SM manages 93.84 GPixel/s. Texture rates are closer: 816.0 GTexel/s for the RTX 4080 SUPER versus 750.7 GTexel/s for the N1X 40SM. FP32 compute shows a clear gap, with the RTX 4080 SUPER at 52.22 TFLOPS and the N1X 40SM at 24.02 TFLOPS. FP16 performance mirrors FP32 on both parts, with each delivering 1:1 ratios.

Memory configurations differ substantially. The RTX 4080 SUPER uses 16 GB of GDDR6X on a 256-bit bus, with 736.3 GB/s bandwidth and memory clocks at 1438 MHz (23 Gbps effective). The N1X 40SM uses 128 GB of LPDDR5X on a 256-bit bus, with 273.2 GB/s bandwidth and memory clocks at 1067 MHz (8.5 Gbps effective). The RTX 4080 SUPER delivers 2.7 times the bandwidth despite having one-eighth the capacity.

Clock speeds favor the RTX 4080 SUPER in boost terms: 2,550 MHz versus 2,346 MHz for the N1X 40SM. Base clocks differ more sharply, with the RTX 4080 SUPER at 2,295 MHz and the N1X 40SM at 741 MHz. The N1X 40SM is an integrated graphics processor (IGP) with no power connectors and no slot width, while the RTX 4080 SUPER is a triple-slot card using a 16-pin connector with a 320 W TDP and a 700 W suggested PSU. The N1X 40SM’s TDP is unknown.

API support also diverges. The RTX 4080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan. Bus interfaces differ: PCIe 4.0 x16 for the RTX 4080 SUPER versus PCIe 5.0 x16 for the N1X 40SM. Display outputs are 1x HDMI and 3x DisplayPort 1.4a for the RTX 4080 SUPER, while the N1X 40SM lists only 1x HDMI.

The Verdict

The data clearly favors the NVIDIA GeForce RTX 4080 SUPER for any workload requiring measured performance. It has verified scores across nine benchmark tests, an average score of 54,209, and a percentile rank of 86. Its nearest rivals are within 2.8% of its average score, meaning it competes at the top of its segment. The card offers 52.22 TFLOPS FP32, 736.3 GB/s memory bandwidth, and full DirectX 12 Ultimate, Vulkan 1.4, and OpenGL 4.6 support. It is a triple-slot, 320 W discrete GPU with a 16-pin connector and requires a 700 W PSU.

The NVIDIA N1X 40SM cannot be recommended based on benchmark evidence because no benchmark evidence exists. Its average score is 0, it has no recorded tests, and its percentile rank of 50 is unsubstantiated. It does offer 128 GB of LPDDR5X memory, which is eight times the capacity of the RTX 4080 SUPER, but bandwidth is far lower at 273.2 GB/s. Its FP32 compute is less than half, and it lacks API support entries for DirectX, OpenGL, and Vulkan. As an IGP with no power connectors, it targets an entirely different form factor.

Users seeking a discrete GPU with proven performance in DX12, Vulkan, OpenCL, and compute workloads should select the RTX 4080 SUPER. Users who require an integrated processor with a very large memory pool and PCIe 5.0 connectivity may consider the N1X 40SM, but the database provides no performance data to validate that choice.
