NVIDIA N1X 48SM vs NVIDIA RTX 6000D Comparison

Where Each One Wins

The recorded data splits these two NVIDIA parts cleanly along workload type. The N1X 48SM has no benchmark entries in the database, so every performance comparison relies on the RTX 6000D's measured results. That does not mean the N1X is absent from the analysis; its architectural profile defines its role.

The RTX 6000D wins every measurable benchmark category. In 3DMark Steel Nomad DX12, it scores 3,522 points. In Geekbench OpenCL, it reaches 388,405 points. These are the only two recorded benchmarks, but they cover both gaming-oriented DirectX 12 workloads and general-purpose compute. The N1X 48SM has zero recorded scores, placing it at the 50th percentile of all GPUs in the database, while the RTX 6000D sits at the 98th percentile.

The N1X 48SM wins on integration. It is an IGP (integrated graphics processor) with no power connectors and no slot width, meaning it mounts directly on the board. The RTX 6000D is a dual-slot add-in card requiring a 16-pin power connector and a 1000 W suggested power supply. For systems where physical space and power delivery are constrained, the N1X is the only option that fits.

Memory capacity favors the N1X. It carries 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The RTX 6000D has 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s. The N1X has more capacity, but the RTX 6000D has over five times the bandwidth. Large working sets that fit within 84 GB will run faster on the RTX 6000D; datasets exceeding 84 GB can only reside on the N1X.

The N1X also wins on display simplicity. It outputs through a single HDMI port. The RTX 6000D provides four DisplayPort 2.1b outputs. For multi-monitor setups, the RTX 6000D is clearly ahead; for a single display, the N1X suffices.

Architecture Differences

Both chips use the Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. The similarities end there. The N1X uses the GB20B chip with a die size of 382 mm². The RTX 6000D uses the GB202 chip with a 750 mm² die, nearly double the area. Transistor counts are unknown for the N1X, while the RTX 6000D packs 92,200 million transistors at a density of 122.9 million per mm².

Clock behavior differs substantially. The N1X has a base clock of 741 MHz and a boost clock of 2,346 MHz. The RTX 6000D starts at 1,992 MHz base and boosts to 2,430 MHz. The RTX 6000D runs at nearly triple the N1X's base clock, though the boost clocks converge somewhat. Memory clocks also diverge: the N1X runs at 1,067 MHz with 8.5 Gbps effective, while the RTX 6000D runs at 1,560 MHz with 25 Gbps effective.

Compute resources heavily favor the RTX 6000D. It has 19,968 shading units versus 6,144 on the N1X. Texture mapping units number 624 versus 384. Raster output units are 192 versus 48. Ray tracing cores stand at 156 versus 48. Tensor cores are 624 versus 192. Every execution resource on the RTX 6000D exceeds the N1X by a factor of at least three, and in some cases four.

The RTX 6000D delivers 97.04 TFLOPS FP32 and 97.04 TFLOPS FP16 (1:1). The N1X delivers 28.83 TFLOPS in both formats. Pixel rate on the RTX 6000D is 466.6 GPixel/s versus 112.6 GPixel/s on the N1X. Texture rate reaches 1,516.3 GTexel/s versus 900.9 GTexel/s. The RTX 6000D leads in every throughput metric.

API support separates them further. The RTX 6000D supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X reports N/A for all three APIs. This indicates the N1X targets specialized or embedded workloads rather than general graphics applications.

Power and physical design reflect their different purposes. The RTX 6000D consumes 600 W TDP, requires a dual-slot cooler, and measures 304 mm by 137 mm by 40 mm. The N1X has unknown TDP, uses an IGP form factor with no slot width, and requires no power connectors. The N1X connects via PCIe 5.0 x16, same as the RTX 6000D.

The Verdict

The data supports a straightforward selection. The RTX 6000D is the performance leader by every recorded metric. Its 98th percentile standing, 97.04 TFLOPS FP32, and 1.40 TB/s bandwidth place it in a different class from the N1X, which sits at the 50th percentile with no benchmark scores.

The N1X 48SM suits systems that need large memory capacity in an integrated form factor. Its 128 GB of LPDDR5X exceeds the RTX 6000D's 84 GB by a significant margin. No power connectors, no slot width, and a single HDMI output indicate a board-level component for specialized appliances rather than a general-purpose workstation GPU.

The RTX 6000D serves users who need maximum compute throughput. Its 19,968 shading units, 624 tensor cores, and 156 ray tracing cores handle heavy parallel workloads. The 4x DisplayPort 2.1b outputs support multi-display environments. The 600 W TDP and 1000 W suggested PSU indicate a serious power draw, but the performance justifies it.

The RTX 6000D's nearest rivals in the database confirm its position. It scores 0.8% above the Tesla V100S PCIe 32 GB, 4.7% above the A100 SXM4 40 GB, 6.1% above the RTX 5000 Ada Generation, and 5.4% below the A100 PCIe 80 GB. These deltas are small, placing the RTX 6000D in a tight competitive cluster. The N1X has no comparable rivals listed.

Choose the N1X when the system requires integrated graphics with 128 GB memory and minimal physical footprint. Choose the RTX 6000D when compute performance and display flexibility matter more than capacity or integration.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two GPUs. The N1X has no recorded benchmark scores at all. Therefore, the comparison relies on the RTX 6000D's absolute scores and the architectural specifications of both parts.

The RTX 6000D scores 3,522 in 3DMark Steel Nomad DX12. This test stresses DirectX 12 rendering performance, including geometry, rasterization, and compute effects. The N1X cannot be measured against this figure directly, but its 48 raster output units and 28.83 TFLOPS FP32 suggest a much lower ceiling than the RTX 6000D's 192 ROPs and 97.04 TFLOPS.

In Geekbench OpenCL, the RTX 6000D scores 388,405 points. OpenCL measures general-purpose compute across heterogeneous workloads. The RTX 6000D's 624 tensor cores and 19,968 shading units provide massive parallel throughput. The N1X's 192 tensor cores and 6,144 shading units represent roughly a third of the execution resources, and its FP32 throughput is 29.7% of the RTX 6000D's.

The RTX 6000D's average benchmark score is 195,964 across its two recorded tests. This places it at the 98th percentile of all GPUs in the database. The N1X sits at the 50th percentile with an average score of zero, reflecting the absence of recorded benchmarks.

The biggest wins for the RTX 6000D come in raw compute throughput. Its FP32 performance of 97.04 TFLOPS is 3.37 times the N1X's 28.83 TFLOPS. Pixel rate is 4.14 times higher at 466.6 GPixel/s versus 112.6 GPixel/s. Texture rate is 1.68 times higher at 1,516.3 GTexel/s versus 900.9 GTexel/s. Memory bandwidth is 5.12 times higher at 1.40 TB/s versus 273.2 GB/s.

The N1X wins on memory capacity, offering 128 GB versus 84 GB, a 52.4% advantage. It also wins on integration, requiring no power connectors and occupying no slot width. These are qualitative advantages that do not appear in benchmark scores but matter for specific deployment scenarios.
