Architecture Differences

Both GPUs share the Blackwell 2.0 architecture and are manufactured by NVIDIA on a 5 nm process at TSMC, yet they diverge sharply in their implementation. The RTX 5080 uses the GB203 chip with a die size of 378 mm² and 45,600 million transistors, resulting in a transistor density of 120.6M per mm². The N1 20SM uses a different chip, the GB20B, with a slightly larger die at 382 mm², though its transistor count is recorded as unknown and no transistor density is available.

The shading resources show the most dramatic difference. The RTX 5080 carries 10,752 shading units, 336 TMUs, and 112 ROPs, while the N1 20SM has 2,560 shading units, 160 TMUs, and only 24 ROPs. Ray tracing cores follow the same pattern: the RTX 5080 has 84 RT cores, the N1 20SM has 20. Tensor cores number 336 on the RTX 5080 versus 80 on the N1 20SM.

Memory architecture diverges in type and capacity. The RTX 5080 uses 16 GB of GDDR7 with a 256-bit bus and 960.0 GB/s bandwidth. The N1 20SM uses 128 GB of LPDDR5X with the same 256-bit bus width but only 273.2 GB/s bandwidth. The N1 20SM's memory clock runs at 1067 MHz with 8.5 Gbps effective, while the RTX 5080's memory clock is 1875 MHz with 30 Gbps effective.

The N1 20SM is classified as an IGP (integrated graphics processor) with a slot width of "IGP" and no power connectors, whereas the RTX 5080 is a dual-slot discrete card requiring a single 16-pin connector and a 750 W suggested PSU. The N1 20SM's TDP is unknown, while the RTX 5080 has a TDP of 360 W. Display outputs also differ: the RTX 5080 offers 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the N1 20SM provides only 1x HDMI.

API support further separates them. The RTX 5080 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM records N/A for DirectX, OpenGL, and Vulkan, indicating it does not expose these standard graphics APIs in the database.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two GPUs. The RTX 5080 has ten individual benchmark scores, while the N1 20SM has none. The RTX 5080's strongest recorded results include a 3DMark Steel Nomad DX12 score of 8,637, a Geekbench OpenCL score of 235,901, and a Geekbench Vulkan score of 255,450. PassMark scores range from 151 in DirectX 12 to 389 in DirectX 9, with a G3D score of 36,565 and a GPU compute score of 21,789.

The absence of N1 20SM benchmark data means no direct comparison can be made on specific tests. However, the compute capability difference is evident from the FP32 throughput figures: the RTX 5080 delivers 56.28 TFLOPS, while the N1 20SM delivers 12.01 TFLOPS. This represents a 4.7x difference in raw floating-point performance. The pixel rate tells a similar story: 293.1 GPixel/s for the RTX 5080 versus 56.30 GPixel/s for the N1 20SM. Texture rate shows 879.3 GTexel/s for the RTX 5080 and 375.4 GTexel/s for the N1 20SM.

The RTX 5080's average benchmark score of 56,083 places it 0.6% ahead of the AMD Radeon 8060S and 0.7% ahead of the AMD Radeon RX 6750 GRE 12 GB. It trails the AMD Radeon RX 9070 GRE by 2.2%. These rival comparisons provide context for the RTX 5080's position in the database, though no such context exists for the N1 20SM given its empty benchmark array.

Clock speeds show substantial gaps. The RTX 5080's base clock is 2295 MHz versus 741 MHz for the N1 20SM. Boost clocks are 2617 MHz and 2346 MHz respectively. Memory clocks are 1875 MHz (30 Gbps effective) for the RTX 5080 and 1067 MHz (8.5 Gbps effective) for the N1 20SM.

Memory capacity and type differ completely: 16 GB GDDR7 for the RTX 5080 against 128 GB LPDDR5X for the N1 20SM. Bandwidth favors the RTX 5080 at 960.0 GB/s versus 273.2 GB/s for the N1 20SM.

Compute resources diverge sharply. Shading units: 10,752 vs 2,560. TMUs: 336 vs 160. ROPs: 112 vs 24. RT cores: 84 vs 20. Tensor cores: 336 vs 80. FP32 and FP16 performance are both 56.28 TFLOPS for the RTX 5080 and 12.01 TFLOPS for the N1 20SM.

Pixel rate is 293.1 GPixel/s for the RTX 5080 and 56.30 GPixel/s for the N1 20SM. Texture rate is 879.3 GTexel/s versus 375.4 GTexel/s.

Physical and power specifications also differ. The RTX 5080 is dual-slot with a 1x 16-pin power connector and a 750 W suggested PSU. The N1 20SM is an IGP with no power connectors and no suggested PSU. TDP is 360 W for the RTX 5080 and unknown for the N1 20SM.

Release dates differ by over a year: 2025-01-29 for the RTX 5080 and 2026-05-31 for the N1 20SM. The RTX 5080 has a launch MSRP of 999 USD; the N1 20SM has no recorded launch MSRP.

The Verdict

The database shows a clear performance hierarchy. The RTX 5080 has an average benchmark score of 56,083 and sits in the 87th percentile of all GPUs. The N1 20SM has an average benchmark score of 0 and sits in the 50th percentile, with no recorded benchmark data to support any performance claims.

The RTX 5080 is a discrete, active-production graphics card with 10,752 shading units, 56.28 TFLOPS FP32 performance, 960.0 GB/s memory bandwidth, and full API support. Its nearest rivals in the database are AMD Radeon models with average scores within 2.3% of its own, indicating it sits in a competitive mid-to-high performance tier.

The N1 20SM is an integrated graphics processor with 2,560 shading units, 12.01 TFLOPS FP32 performance, and 273.2 GB/s memory bandwidth. It has no benchmark scores, no API support recorded, and no nearest rivals. Its 128 GB LPDDR5X memory capacity is notable, but the 256-bit bus and lower bandwidth suggest a design focused on capacity rather than throughput.

For users seeking a GPU with recorded performance data, the RTX 5080 is the only option between these two that offers measurable benchmark results. The data indicates the RTX 5080 delivers 4.7x the FP32 throughput of the N1 20SM and 5.2x the pixel rate. The N1 20SM's sole advantage lies in memory capacity: 128 GB versus 16 GB, a 8x difference.

Where Each One Wins

The RTX 5080 wins on every compute and graphics metric recorded in the database. Its 56.28 TFLOPS FP32 performance exceeds the N1 20SM's 12.01 TFLOPS by a factor of 4.7. The 293.1 GPixel/s pixel rate and 879.3 GTexel/s texture rate outpace the N1 20SM's 56.30 GPixel/s and 375.4 GTexel/s respectively. Memory bandwidth of 960.0 GB/s compares favorably to 273.2 GB/s.

The RTX 5080 also wins on clock speeds, with a base clock of 2295 MHz versus 741 MHz and a boost clock of 2617 MHz versus 2346 MHz. Its 84 RT cores and 336 tensor cores provide hardware acceleration capabilities that the N1 20SM's 20 RT cores and 80 tensor cores cannot match in scale.

The N1 20SM wins on memory capacity with 128 GB of LPDDR5X versus the RTX 5080's 16 GB of GDDR7. This 8x capacity difference could benefit workloads that require large datasets in memory, though the 273.2 GB/s bandwidth limits how quickly that memory can be accessed. The N1 20SM's IGP form factor with no power connectors also means it consumes no dedicated power from a PSU, though its TDP is unknown and cannot be compared directly.

The N1 20SM's release date of 2026-05-31 is later than the RTX 5080's 2025-01-29, but no benchmark data exists to determine whether this newer release translates into performance gains. The RTX 5080 remains the only one of the two with a measurable performance profile, while the N1 20SM's capabilities in the database are limited to its specification sheet alone.
