NVIDIA N1 20SM vs NVIDIA RTX 6000D Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the NVIDIA N1 20SM and the NVIDIA RTX 6000D. The N1 20SM has no benchmark entries, while the RTX 6000D has two recorded scores: 3,522 in 3DMark Steel Nomad DX12 and 388,405 in Geekbench OpenCL. These scores place the RTX 6000D at the 98th percentile among all GPUs in the database, with an average benchmark score of 195,964.

Without overlapping tests, the comparison relies on architectural and specification differences. The RTX 6000D delivers 97.04 TFLOPS of FP32 compute, while the N1 20SM delivers 12.01 TFLOPS. That is an 8.1x difference in raw floating-point throughput. The RTX 6000D also produces 1,516.3 GTexel/s of texture fill rate versus 375.4 GTexel/s on the N1 20SM, a 4x gap. Pixel throughput favors the RTX 6000D at 466.6 GPixel/s compared to 56.30 GPixel/s, an 8.3x difference.

The RTX 6000D's nearest rivals in the database provide context for its performance tier. The Tesla V100S PCIe 32 GB scores 194,415, which is 0.8% lower than the RTX 6000D's average. The A100 SXM4 40 GB scores 187,147, sitting 4.7% behind. The RTX 5000 Ada Generation scores 184,664, a 6.1% deficit. Meanwhile, the A100 PCIe 80 GB scores 207,124, which is 5.4% ahead of the RTX 6000D. These deltas indicate the RTX 6000D sits in a competitive range among high-end compute accelerators, slightly above some A100 variants but below the A100 PCIe 80 GB.

The N1 20SM has no nearest rival data and no average benchmark score, so its performance cannot be positioned relative to other GPUs. Its 50th percentile ranking is a default placeholder, not a measured result.

Where Each One Wins

The RTX 6000D wins decisively in every measurable compute category. Its FP32 throughput of 97.04 TFLOPS suits heavy parallel workloads, scientific simulation, and AI training. The 624 tensor cores and 156 RT cores provide dedicated hardware for neural network operations and ray tracing. The 1.40 TB/s memory bandwidth, delivered over a 448-bit GDDR7 interface, enables rapid data movement for large datasets. The 84 GB memory capacity supports models and scenes that exceed the N1 20SM's allocation.

The N1 20SM wins in power efficiency and physical footprint. The database lists its TDP as unknown, but the slot width is IGP, meaning it integrates into a system without a dedicated power connector. The RTX 6000D requires a 600 W TDP, a single 16-pin connector, and a suggested 1000 W PSU. The N1 20SM draws no external power connector, which makes it suitable for compact or low-power systems. Its 128 GB of LPDDR5X memory exceeds the RTX 6000D's 84 GB, giving the N1 20SM a capacity advantage for memory-bound workloads that fit within its lower bandwidth.

The RTX 6000D also wins in API support. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for all three APIs, indicating no conventional graphics API compatibility in the recorded data. For gaming or general graphics workloads, the RTX 6000D is the only viable option between the two.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture and are fabricated on a 5 nm process at TSMC. The chips differ substantially. The N1 20SM uses the GB20B chip with a die size of 382 mm². The RTX 6000D uses the GB202 chip with a die size of 750 mm², nearly double the area. The RTX 6000D contains 92,200 million transistors with a density of 122.9M per mm². The N1 20SM's transistor count is unknown in the database.

The shading unit counts reflect the scale difference. The N1 20SM has 2,560 shading units, 160 TMUs, and 24 ROPs. The RTX 6000D has 19,968 shading units, 624 TMUs, and 192 ROPs. That is 7.8x more shading units, 3.9x more TMUs, and 8x more ROPs. The RTX 6000D also has 156 RT cores versus 20 on the N1 20SM, and 624 tensor cores versus 80. The tensor core advantage is 7.8x, matching the shading unit ratio.

Clock speeds differ as well. The N1 20SM has a base clock of 741 MHz and a boost of 2,346 MHz. The RTX 6000D has a base of 1,992 MHz and a boost of 2,430 MHz. The RTX 6000D's higher base clock indicates sustained performance under load, while the N1 20SM's lower base suggests it relies on boost behavior for peak output.

Memory architecture diverges completely. The N1 20SM uses LPDDR5X at 1,067 MHz with an effective data rate of 8.5 Gbps, over a 256-bit bus, yielding 273.2 GB/s. The RTX 6000D uses GDDR7 at 1,560 MHz with 25 Gbps effective, over a 448-bit bus, yielding 1.40 TB/s. The bandwidth difference is 5.1x. However, the N1 20SM has 128 GB of memory versus 84 GB, a 52% capacity advantage.

Specification Differences

The two GPUs differ across nearly every specification field. The N1 20SM is an IGP with no power connectors and a single HDMI output. The RTX 6000D is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width, with four DisplayPort 2.1b outputs and one 16-pin power connector. The RTX 6000D has a 600 W TDP and a suggested 1000 W PSU, while the N1 20SM lists unknown TDP and no PSU requirement.

The N1 20SM uses the GB20B chip at 5 nm, while the RTX 6000D uses the GB202 chip at 5 nm. The die sizes are 382 mm² versus 750 mm². The RTX 6000D has a known transistor count of 92,200 million; the N1 20SM's is unknown. The RTX 6000D's transistor density is 122.9M per mm², which is not listed for the N1 20SM.

Memory configurations differ in capacity, type, bus width, and bandwidth. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s. The RTX 6000D has 84 GB of GDDR7 on a 448-bit bus with 1.40 TB/s.

Compute resources differ in every category. The N1 20SM has 2,560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The RTX 6000D has 19,968 shading units, 624 TMUs, 192 ROPs, 156 RT cores, and 624 tensor cores. The FP32 and FP16 throughput are both 12.01 TFLOPS on the N1 20SM and 97.04 TFLOPS on the RTX 6000D.

The RTX 6000D supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for all three. The RTX 6000D's release date is 2025-07-13, while the N1 20SM's is 2026-05-31.

The Verdict

The RTX 6000D is the clear choice for any workload that demands maximum compute throughput. Its 97.04 TFLOPS FP32 performance, 1.40 TB/s bandwidth, and 156 RT cores place it in the top 2% of all GPUs in the database. The recorded benchmark scores, 3,522 in 3DMark Steel Nomad DX12 and 388,405 in Geekbench OpenCL, confirm its position near the A100 and V100S class of accelerators. The 600 W TDP and required 1000 W PSU are significant system demands, but the performance justifies them for professional compute environments.

The N1 20SM serves a different purpose. Its IGP form factor, no external power connector, and 128 GB of LPDDR5X memory make it suitable for systems where physical space, power delivery, and memory capacity take priority over raw speed. The 273.2 GB/s bandwidth is sufficient for memory-resident datasets, but the 12.01 TFLOPS compute ceiling limits it to lighter workloads. The lack of DirectX, OpenGL, and Vulkan support means it cannot function as a general-purpose graphics card.

The data indicates the RTX 6000D is the superior choice for AI training, scientific simulation, and high-end rendering. The N1 20SM is appropriate for integrated, low-power deployments where capacity matters more than throughput. The 8.1x FP32 gap and 5.1x bandwidth gap are decisive in any performance comparison. The N1 20SM's 128 GB capacity is its only clear advantage, and that advantage applies only to workloads that fit within its bandwidth constraints. For most users, the RTX 6000D's benchmark-validated performance makes it the practical pick.
