NVIDIA GeForce RTX 5080 SUPER vs NVIDIA N1 20SM Comparison

FAQ

Q: What is the average benchmark score for the NVIDIA GeForce RTX 5080 SUPER?

A: The recorded data shows a single benchmark result for the RTX 5080 SUPER in 3DMark Steel Nomad DX12, with a score of 3075. This places it at the 19th percentile of all GPUs in the database.

Q: Does the NVIDIA N1 20SM have any benchmark scores?

A: No. The database lists no benchmark entries for the N1 20SM, and its average benchmark score is recorded as 0. It occupies the 50th percentile slot, but that figure is derived from the absence of test data rather than measured performance.

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

A: The RTX 5080 SUPER sits within a narrow band of similar-scoring GPUs. It trails the NVIDIA Quadro P1000 by 2.8% (3163 vs 3075) and the Intel Arc Pro B60 by 3.4% (3182 vs 3075). It leads the NVIDIA GeForce 820A by 3.1% (2983 vs 3075) and the NVIDIA GeForce GTX 860M by 3.6% (2967 vs 3075).

Q: What are the memory configurations of the two GPUs?

A: The RTX 5080 SUPER uses 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s of bandwidth. The N1 20SM uses 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth.

Q: Which GPU has the higher shader core count?

A: The RTX 5080 SUPER has 10,752 shading units, while the N1 20SM has 2,560 shading units. That is a 4.2x difference in raw shader count.

Q: What is the release timeline for these products?

A: The RTX 5080 SUPER has a release date of December 31, 2025. The N1 20SM has a release date of May 31, 2026.

Architecture Differences

Both GPUs share the Blackwell 2.0 architecture and are fabricated by TSMC on a 5 nm process, but they diverge sharply in nearly every other architectural dimension.

The RTX 5080 SUPER uses the GB203 chip with 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per mm². The N1 20SM uses the GB20B chip with a die size of 382 mm², though its transistor count is listed as unknown, so no density figure can be computed. The die sizes are close, but the transistor budgets are likely very different given the performance gap.

The RTX 5080 SUPER is a discrete add-in board with dual-slot cooling and a 1x 16-pin power connector. The N1 20SM is an integrated graphics processor (IGP) with no power connectors and no slot width beyond the IGP designation. This reflects fundamentally different design goals: one is a high-power desktop component, the other is an integrated solution.

Clock behavior differs substantially. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost clock of 2617 MHz. The N1 20SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, indicating a wide frequency range that suggests aggressive power management or thermal constraints.

The memory subsystems are architecturally distinct. The RTX 5080 SUPER pairs 24 GB of GDDR7 with a 256-bit bus and 1.02 TB/s bandwidth. The N1 20SM uses 128 GB of LPDDR5X on the same 256-bit bus width but achieves only 273.2 GB/s. The memory clock difference is stark: 2000 MHz (32 Gbps effective) for the RTX 5080 SUPER versus 1067 MHz (8.5 Gbps effective) for the N1 20SM.

Fixed-function hardware also diverges. The RTX 5080 SUPER has 336 texture mapping units, 112 ROPs, 84 RT cores, and 336 tensor cores. The N1 20SM has 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The RTX 5080 SUPER leads in every category, with 2.1x the TMUs, 4.7x the ROPs, 4.2x the RT cores, and 4.2x the tensor cores.

API support is another major difference. The RTX 5080 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, meaning its API compatibility is not recorded in the database.

Display outputs also differ: the RTX 5080 SUPER provides 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the N1 20SM lists only 1x HDMI.

The production status for both is Active, but the RTX 5080 SUPER has a launch MSRP of 999 USD, while the N1 20SM has no recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries comparing the RTX 5080 SUPER against the N1 20SM. The wins counter shows 0 for both sides. This means a conventional benchmark comparison cannot be constructed from recorded test results.

However, the available data allows for a derived comparison. The RTX 5080 SUPER has one benchmark score of 3075 in 3DMark Steel Nomad DX12. The N1 20SM has zero benchmark scores. In the absence of direct measurements, the performance relationship must be inferred from architectural specifications.

The FP32 compute figures provide a clear signal. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 performance. The N1 20SM delivers 12.01 TFLOPS. That is a 4.7x advantage for the RTX 5080 SUPER. FP16 performance is identical to FP32 for both parts, with the RTX 5080 SUPER at 56.28 TFLOPS and the N1 20SM at 12.01 TFLOPS.

Pixel throughput shows a similar gap. The RTX 5080 SUPER achieves 293.1 GPixel/s, while the N1 20SM manages 56.30 GPixel/s, a 5.2x difference. Texture throughput favors the RTX 5080 SUPER at 879.3 GTexel/s versus 375.4 GTexel/s, a 2.3x advantage.

The RTX 5080 SUPER's nearest rivals in the database are instructive. It scores within 3.6% of the NVIDIA GeForce GTX 860M and within 2.8% of the NVIDIA Quadro P1000. These are older, lower-tier parts, which indicates the recorded score for the RTX 5080 SUPER may not reflect its full capability. The 19th percentile placement suggests the single benchmark result understates the hardware relative to its specifications.

The N1 20SM, with no benchmark data, cannot be positioned against any rivals. Its 50th percentile is a placeholder, not a measured outcome.

The bandwidth differential reinforces the compute gap. The RTX 5080 SUPER has 1.02 TB/s of memory bandwidth, which is 3.7x the N1 20SM's 273.2 GB/s. For memory-bound workloads, this is a decisive factor.

The thermal and power envelopes also differ, though the N1 20SM's TDP is listed as unknown. The RTX 5080 SUPER has a TDP of 415 W, which is consistent with a high-performance discrete GPU. The N1 20SM, as an IGP with no power connectors, is clearly designed for a much lower power budget.

The Verdict

The data shows two products with the same architecture name but entirely different purposes. The RTX 5080 SUPER is a high-performance discrete GPU with a 3075 benchmark score, 56.28 TFLOPS of FP32 compute, 1.02 TB/s memory bandwidth, and a 415 W TDP. The N1 20SM is an integrated processor with no benchmark scores, 12.01 TFLOPS of FP32 compute, 273.2 GB/s memory bandwidth, and an unknown TDP.

For users who need maximum graphics throughput, the RTX 5080 SUPER is the clear choice based on every recorded metric. It leads in shader count by 4.2x, in FP32 by 4.7x, in pixel rate by 5.2x, in texture rate by 2.3x, and in memory bandwidth by 3.7x. Its 24 GB of GDDR7 memory is less than the N1 20SM's 128 GB of LPDDR5X, but the bandwidth advantage is overwhelming.

The N1 20SM's 128 GB memory capacity is its sole advantage. That capacity, combined with its IGP form factor and lack of power connectors, indicates a specialized role, likely for systems where large memory pools matter more than raw graphics speed. The absence of any benchmark scores means performance cannot be verified, and the lack of DirectX, OpenGL, and Vulkan support in the database further limits its applicability for standard graphics workloads.

The RTX 5080 SUPER's 19th percentile placement among all GPUs is notable. Its nearest rivals are all older or lower-tier parts, and it sits within a small cluster of scores from 2967 to 3182. This suggests the recorded benchmark may not capture the full capability of the hardware, or that the test conditions were constrained.

For compute-heavy applications, the RTX 5080 SUPER delivers 4.7x the FP32 throughput of the N1 20SM. For memory-heavy applications, the N1 20SM offers 5.3x the capacity but only 26.8% of the bandwidth. The tradeoff is stark: capacity versus speed.

The RTX 5080 SUPER is an active production GPU with a known release date of December 31, 2025, and a launch MSRP of 999 USD. The N1 20SM has a later release date of May 31, 2026, and no recorded MSRP. Both are listed as Active in production status.

The verdict from the data is straightforward. The RTX 5080 SUPER is the higher-performing part by every measurable specification except memory capacity. The N1 20SM is a distinct product category with an unmeasured performance profile and a unique memory configuration. Users requiring verified graphics performance should select the RTX 5080 SUPER. Users requiring maximum memory capacity in an integrated form factor would consider the N1 20SM, but without benchmark evidence to validate its performance.
