NVIDIA GeForce RTX 5080 SUPER vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the NVIDIA GeForce RTX 5080 SUPER and the NVIDIA N1X 40SM. The head-to-head benchmark array is empty, and neither product registers a win in direct comparison. This absence of comparative test data is itself informative: the two parts occupy entirely different segments of the market, and the database currently holds only a single benchmark entry for the RTX 5080 SUPER, with no recorded benchmark scores for the N1X 40SM.

The RTX 5080 SUPER has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 3075. This places the card at the 19th percentile among all GPUs in the database. The nearest rival data provides context for this score. The NVIDIA Quadro P1000 averages 3163, which is 2.8% higher than the RTX 5080 SUPER's recorded result. The Intel Arc Pro B60 averages 3182, 3.4% higher. Conversely, the NVIDIA GeForce 820A averages 2983, which is 3.1% lower, and the NVIDIA GeForce GTX 860M averages 2967, 3.6% lower. These deltas indicate that the RTX 5080 SUPER's single score sits within a narrow band of roughly plus or minus 3.6% relative to its nearest recorded rivals. The spread between the lowest and highest of these neighboring scores is only about 7.2%, suggesting that the 3DMark Steel Nomad workload in this particular configuration does not strongly differentiate these products.

The N1X 40SM has no benchmark entries in the database. Its average benchmark score is recorded as zero, and it has no nearest rivals listed. The percentile field for the N1X 40SM is 50, which in the absence of actual scores likely reflects a default or positional ranking rather than a performance-derived value. Consequently, any quantitative performance comparison between the two cards cannot be drawn from direct measurements.

The FP32 compute figures offer a separate quantitative view, though these are specification-derived rather than benchmark-derived. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 performance. The N1X 40SM delivers 24.02 TFLOPS. The RTX 5080 SUPER therefore provides 2.34 times the FP32 throughput of the N1X 40SM, a 134% advantage. Pixel rate follows a similar pattern: the RTX 5080 SUPER reaches 293.1 GPixel/s versus 93.84 GPixel/s for the N1X 40SM, a 3.1x difference. Texture rate shows a smaller gap: 879.3 GTexel/s versus 750.7 GTexel/s, a 17.1% advantage for the RTX 5080 SUPER. Memory bandwidth diverges sharply: the RTX 5080 SUPER delivers 1.02 TB/s, while the N1X 40SM manages 273.2 GB/s, a 3.7x difference in favor of the discrete card.

FAQ

Q: Which product has the higher recorded benchmark score?

A: Only the NVIDIA GeForce RTX 5080 SUPER has a recorded benchmark score in the database: 3075 in 3DMark Steel Nomad DX12. The NVIDIA N1X 40SM has no recorded benchmark entries, and its average benchmark score is listed as zero.

Q: How does the RTX 5080 SUPER compare to its nearest rivals in the database?

A: The RTX 5080 SUPER's score of 3075 is 2.8% below the NVIDIA Quadro P1000's average of 3163 and 3.4% below the Intel Arc Pro B60's average of 3182. It is 3.1% above the NVIDIA GeForce 820A's average of 2983 and 3.6% above the NVIDIA GeForce GTX 860M's average of 2967.

Q: What are the memory specifications of each product?

A: The RTX 5080 SUPER uses 24 GB of GDDR7 memory on a 256-bit bus, with 1.02 TB/s of bandwidth and 2000 MHz memory clock (32 Gbps effective). The N1X 40SM uses 128 GB of LPDDR5X memory on a 256-bit bus, with 273.2 GB/s of bandwidth and 1067 MHz memory clock (8.5 Gbps effective).

Q: Do both products support the same graphics APIs?

A: No. The RTX 5080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A, indicating no supported graphics APIs are recorded for that part.

The Verdict

The data points to two distinct usage profiles. The NVIDIA GeForce RTX 5080 SUPER is a discrete, actively produced graphics card with a recorded benchmark score, a full API feature set, and substantially higher compute, pixel, and memory bandwidth figures. Its FP32 throughput of 56.28 TFLOPS is 2.34x the N1X 40SM's 24.02 TFLOPS. Its pixel rate of 293.1 GPixel/s is 3.1x the N1X 40SM's 93.84 GPixel/s. Its memory bandwidth of 1.02 TB/s is 3.7x the N1X 40SM's 273.2 GB/s. These are large, consistent margins across rendering and compute workloads.

The NVIDIA N1X 40SM is an integrated graphics processor (IGP) with no benchmark entries, no recorded API support, and no nearest rival data. Its 128 GB of LPDDR5X memory is 5.3x the RTX 5080 SUPER's 24 GB, which is the only major specification where it leads. Its texture rate of 750.7 GTexel/s is within 17.1% of the RTX 5080 SUPER's 879.3 GTexel/s, a smaller gap than the other compute metrics. The N1X 40SM also has a larger die at 382 mm² versus 378 mm², though its transistor count is listed as unknown.

The percentile data reinforces the separation. The RTX 5080 SUPER sits at the 19th percentile among all GPUs, with a concrete score of 3075 and four nearby rivals. The N1X 40SM sits at the 50th percentile, but with no scores behind that ranking. The 19th percentile figure for the RTX 5080 SUPER indicates that the majority of GPUs in the database score higher on the 3DMark Steel Nomad DX12 test, which is consistent with a single entry that has not been corroborated by additional runs.

For users selecting between these parts, the choice depends on whether the workload requires a discrete graphics solution or an integrated one. The RTX 5080 SUPER offers a launch MSRP of 999 USD and is available as a dual-slot card with a 1x 16-pin power connector, a 415 W TDP, and dimensions of 304 mm length, 137 mm height, and 40 mm width. The N1X 40SM is an IGP with no power connectors, no TDP listed, and no dimensions recorded. The RTX 5080 SUPER is the only one of the two with any demonstrated performance data, and its specification sheet shows higher rates across every rendering and compute category except memory capacity and texture rate, where the N1X 40SM holds a narrow texture rate deficit but a large memory capacity lead.

Architecture Differences

Both products use the Blackwell 2.0 architecture and are manufactured by NVIDIA on a 5 nm process at TSMC. The RTX 5080 SUPER uses the GB203 chip, while the N1X 40SM uses the GB20B chip. The GB203 has 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6M per mm². The GB20B's transistor count is unknown, but its die size is 382 mm², slightly larger than the GB203.

The compute resource allocation differs substantially. The RTX 5080 SUPER contains 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The N1X 40SM contains 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The RTX 5080 SUPER has 2.1x the shading units, 2.1x the RT cores, 2.1x the tensor cores, and 2.8x the ROPs. The TMU count is closer, 336 versus 320, a 5% difference.

Clock behavior also differs. The RTX 5080 SUPER's base clock of 2295 MHz is 3.1x the N1X 40SM's base clock of 741 MHz. The boost clocks are closer: 2617 MHz versus 2346 MHz, an 11.6% gap. The memory clocks diverge more sharply, with the RTX 5080 SUPER running at 2000 MHz (32 Gbps effective) versus 1067 MHz (8.5 Gbps effective) for the N1X 40SM.

Memory architecture shares the same 256-bit bus width, but the memory types and capacities differ. The RTX 5080 SUPER uses 24 GB of GDDR7, while the N1X 40SM uses 128 GB of LPDDR5X. The resulting bandwidth is 1.02 TB/s versus 273.2 GB/s. The N1X 40SM's 128 GB capacity is 5.3x the RTX 5080 SUPER's 24 GB, which is the primary architectural advantage for the IGP part.

API support separates the two products completely. The RTX 5080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists DirectX, OpenGL, and Vulkan all as N/A. The RTX 5080 SUPER also provides a richer set of display outputs: 1x HDMI 2.1b and 3x DisplayPort 2.1b, versus a single HDMI output for the N1X 40SM. Power delivery follows the form factor: the RTX 5080 SUPER uses a 1x 16-pin connector with a 415 W TDP and dual-slot footprint, while the N1X 40SM is an IGP with no power connectors and no TDP listed. Both use a PCIe 5.0 x16 bus interface. The RTX 5080 SUPER's release date is recorded as 2025-12-31, and the N1X 40SM's as 2026-05-31.
