NVIDIA N1 20SM vs NVIDIA RTX 5880 Ada Generation Comparison

The Verdict

The database comparison between the NVIDIA N1 20SM and the NVIDIA RTX 5880 Ada Generation shows two fundamentally different products with almost no overlap in intended use. The N1 20SM is an integrated graphics processor (IGP) built on the Blackwell 2.0 architecture, while the RTX 5880 Ada Generation is a dual-slot workstation card built on Ada Lovelace. The recorded data shows the RTX 5880 holds the 85th percentile among all GPUs, while the N1 20SM sits at the 50th percentile with no benchmark scores recorded in the database. The RTX 5880 has an average benchmark score of 45,972, while the N1 20SM has no measurable score, making any direct performance comparison impossible from the available data.

The N1 20SM targets systems where a discrete GPU is not an option, given its IGP form factor, no power connectors, and single HDMI output. The RTX 5880 Ada Generation, with its 285 W TDP, 600 W suggested PSU, and dual-slot footprint, targets professional workstations requiring sustained compute throughput. The data indicates the RTX 5880 is the only one of the two with API support, listing DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for all three APIs. For any workload relying on those APIs, the RTX 5880 is the only viable choice.

Architecture Differences

The two GPUs come from different architectural generations. The N1 20SM uses the GB20B chip built on Blackwell 2.0, part of the Blackwell IGP (N1x) generation, fabricated on a 5 nm process at TSMC with a die size of 382 mm². The RTX 5880 Ada Generation uses the AD102 chip built on Ada Lovelace, part of the Workstation Ada (x000A) generation, also fabricated on a 5 nm process at TSMC, but with a substantially larger die at 609 mm² and 76,300 million transistors, yielding a transistor density of 125.3M per mm². The N1 20SM's transistor count is listed as unknown.

Memory architecture differs sharply. The N1 20SM carries 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth with memory clocked at 1067 MHz (8.5 Gbps effective). The RTX 5880 carries 48 GB of GDDR6 on a 384-bit bus, delivering 864.0 GB/s of bandwidth with memory clocked at 2250 MHz (18 Gbps effective). The RTX 5880 has over three times the memory bandwidth despite having less than half the capacity.

Computational resources also diverge significantly. The N1 20SM has 2,560 shading units, 160 texture mapping units, 24 ROPs, 20 RT cores, and 80 tensor cores. The RTX 5880 has 14,080 shading units, 440 TMUs, 176 ROPs, 110 RT cores, and 440 tensor cores. The RTX 5880 leads in every count, with 5.5 times the shading units, 2.75 times the TMUs, 7.3 times the ROPs, 5.5 times the RT cores, and 5.5 times the tensor cores.

Clock behavior also differs. The N1 20SM has a base clock of 741 MHz and a boost clock of 2,346 MHz. The RTX 5880 has a base clock of 975 MHz and a boost clock of 2,460 MHz. The RTX 5880 starts higher and boosts slightly higher, though the N1 20SM's boost clock is close.

The physical and electrical specifications reflect their roles. The N1 20SM is an IGP with no power connectors and no listed TDP, while the RTX 5880 is a dual-slot card with a 285 W TDP, a single 16-pin power connector, and a suggested PSU of 600 W. The RTX 5880 measures 267 mm in length and 112 mm in height. The N1 20SM has no listed dimensions.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two products. The wins counter shows zero for both. The N1 20SM has no benchmarks listed at all, so there is no measured performance data to compare directly. The RTX 5880 Ada Generation has eight recorded benchmark scores: Geekbench OpenCL at 326,898, Passmark DirectX 10 at 167, Passmark DirectX 11 at 228, Passmark DirectX 12 at 70, Passmark DirectX 9 at 335, Passmark G2D at 777, Passmark G3D at 25,096, and Passmark GPU Compute at 14,208.

The RTX 5880's average benchmark score of 45,972 places it near the NVIDIA RTX A2000 (46,043, delta of -0.2%), the AMD Radeon RX 5600M (46,601, delta of -1.4%), the Intel Arc A730M (45,592, delta of 0.8%), and the AMD Radeon Pro 5500 XT (45,384, delta of 1.3%). The nearest rival data shows the RTX 5880 essentially tied with these products in average score, despite having far greater raw compute specifications. The RTX A2000 is 0.2% ahead, the RX 5600M is 1.4% ahead, while the Arc A730M is 0.8% behind and the Pro 5500 XT is 1.3% behind. These deltas indicate the RTX 5880's average score sits in a narrow band around 45,972, with no rival exceeding a 1.4% difference.

The RTX 5880's percentile rank of 85 among all GPUs suggests it outperforms most products in the database, but its nearest rivals cluster tightly, implying that the average score metric does not capture the full performance spread. The Passmark G3D score of 25,096 and GPU Compute score of 14,208 are the more granular data points. The DirectX 9 score of 335 is the highest among the Passmark DirectX tests, followed by DirectX 11 at 228, DirectX 10 at 167, and DirectX 12 at 70. The low DirectX 12 score relative to older API versions suggests that the RTX 5880's driver or architecture may not scale as well in that specific test.

Without any N1 20SM benchmark data, the comparison rests on architectural differences rather than measured outcomes. The N1 20SM's fp32 throughput is 12.01 TFLOPS, and its fp16 throughput is also 12.01 TFLOPS at a 1:1 ratio. The RTX 5880's fp32 throughput is 69.27 TFLOPS, with fp16 also at 69.27 TFLOPS at 1:1. The RTX 5880 delivers 5.77 times the single-precision compute of the N1 20SM based on the recorded specifications.

Pixel and texture rates follow the same pattern. The N1 20SM achieves 56.30 GPixel/s and 375.4 GTexel/s. The RTX 5880 achieves 433.0 GPixel/s and 1,082.4 GTexel/s. The RTX 5880 leads by 7.69 times in pixel rate and 2.88 times in texture rate.

Where Each One Wins

The RTX 5880 Ada Generation wins in every measurable specification category where both have recorded data. It has more shading units, TMUs, ROPs, RT cores, and tensor cores. It has higher base and boost clocks, higher memory bandwidth, higher pixel rate, higher texture rate, and higher fp32 and fp16 throughput. It also has API support across DirectX, OpenGL, and Vulkan, while the N1 20SM has none listed. The RTX 5880's 85th percentile rank and average benchmark score of 45,972 give it a measurable performance profile, while the N1 20SM has no benchmark scores.

The N1 20SM wins in memory capacity, carrying 128 GB compared to the RTX 5880's 48 GB. It also has a smaller die at 382 mm² versus 609 mm², and it uses LPDDR5X memory, which is a different technology from the RTX 5880's GDDR6. The N1 20SM is an IGP, meaning it requires no power connectors and no dedicated power supply guidance, making it suitable for integrated systems. Its PCIe 5.0 x16 bus interface is newer than the RTX 5880's PCIe 4.0 x16 interface. The N1 20SM also has a later release date of 2026-05-31 compared to the RTX 5880's 2024-01-04.

The performance data indicates the RTX 5880 is the clear choice for compute-heavy workloads, given its 69.27 TFLOPS fp32 throughput and 864.0 GB/s bandwidth. The N1 20SM's 12.01 TFLOPS and 273.2 GB/s bandwidth suggest a more modest capability, appropriate for integrated graphics scenarios. The RTX 5880's 110 RT cores versus the N1 20SM's 20 RT cores indicates a substantial advantage in ray tracing workloads, and its 440 tensor cores versus 80 tensor cores points to a large lead in AI inference tasks.

The N1 20SM's 128 GB memory capacity could be advantageous for memory-bound workloads that require large datasets resident in VRAM, but the RTX 5880's much higher bandwidth may compensate for the lower capacity in many scenarios. The bus interface difference, with the N1 20SM on PCIe 5.0 x16 and the RTX 5880 on PCIe 4.0 x16, may affect data transfer rates with the host system, but no benchmark data quantifies this impact.
