NVIDIA N1X 48SM vs NVIDIA RTX PRO 6000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the NVIDIA N1X 48SM and the NVIDIA RTX PRO 6000 Blackwell. The recorded data shows zero wins for either part in direct matchup testing, and no individual benchmark scores are listed for the N1X 48SM. The RTX PRO 6000 Blackwell, however, has a single recorded benchmark result: a 3DMark Steel Nomad DX12 score of 16,408. This places it at the 59th percentile among all GPUs in the database.

Comparing the two parts requires examining their raw computational specifications rather than direct test results. The RTX PRO 6000 Blackwell delivers 126.0 TFLOPS of FP32 performance, while the N1X 48SM delivers 28.83 TFLOPS. That is a 4.37x advantage for the RTX PRO 6000 in raw floating-point throughput. The pixel rate difference is even more pronounced: 502.5 GPixel/s versus 112.6 GPixel/s, a 4.46x gap. Texture rate shows a 2.18x difference, with the RTX PRO 6000 producing 1,968.0 GTexel/s against 900.9 GTexel/s for the N1X 48SM.

The RTX PRO 6000 Blackwell also holds a decisive lead in memory bandwidth. Its GDDR7 memory, running at 1750 MHz with a 512-bit bus, achieves 1.79 TB/s. The N1X 48SM uses LPDDR5X at 1067 MHz on a 256-bit bus, yielding 273.2 GB/s. That represents a 6.55x bandwidth advantage for the RTX PRO 6000, which directly impacts texture streaming, large dataset handling, and high-resolution rendering workloads.

The N1X 48SM counters with a larger memory capacity: 128 GB versus 96 GB. This 32 GB difference favors the N1X for workloads that require holding very large models or datasets entirely in VRAM, even if the memory itself operates at lower speed. The N1X also draws no external power, using an IGP slot width with no power connectors, whereas the RTX PRO 6000 requires a 600 W TDP, a single 16-pin connector, and a 1000 W suggested PSU. Those are operational constraints, not performance metrics, but they define where each part can physically be deployed.

In terms of nearest rivals, the RTX PRO 6000 Blackwell sits in a tight cluster. The AMD Radeon PRO W7500 scores 16,415, a 0% delta. The AMD Radeon RX 5700 XT scores 16,361, a 0.3% delta. The AMD Radeon Pro 5600M scores 16,351, a 0.4% delta. The NVIDIA GeForce RTX 5090 D V2 scores 16,504, a -0.6% delta, meaning the RTX PRO 6000 trails that card by about half a percent. The RTX PRO 6000's 16,408 score is effectively tied with these rivals, all within a 0.9% spread. This indicates the benchmark result is not a differentiator at this tier; the margins are within noise.

The Verdict

The data points to two completely different deployment profiles. The RTX PRO 6000 Blackwell is the compute and rendering powerhouse. Its FP32 throughput, pixel rate, texture rate, and memory bandwidth all exceed the N1X 48SM by factors ranging from 2.18x to 6.55x. The N1X 48SM, by contrast, is a low-power integrated graphics processor with a larger memory pool but far lower throughput. Neither part is a substitute for the other.

The RTX PRO 6000 is the only one of the two with recorded benchmark data, and that data places it in the upper half of the database at the 59th percentile. Its nearest rivals are all within 0.6% of its score, so the benchmark performance is competitive but not dominant within its immediate peer group. The N1X 48SM has no benchmark scores and sits at the 50th percentile by default, which reflects the absence of measurement data rather than a measured performance level.

The RTX PRO 6000 also holds the advantage in API support. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for all three APIs. For any application that relies on these graphics APIs, the RTX PRO 6000 is the only viable option. The N1X 48SM's API status is undefined in the database, making it unsuitable for standard graphics workloads that require these interfaces.

The RTX PRO 6000 launched on 2025-03-17 with a launch MSRP of 8,565 USD. The N1X 48SM launched on 2026-05-31 with no launch MSRP recorded. The production status for both is Active. The RTX PRO 6000's predecessor is Workstation Ada; the N1X has no predecessor listed.

Where Each One Wins

The RTX PRO 6000 Blackwell wins in every measured performance category. FP32 compute is 126.0 TFLOPS versus 28.83 TFLOPS. Pixel throughput is 502.5 GPixel/s versus 112.6 GPixel/s. Texture throughput is 1,968.0 GTexel/s versus 900.9 GTexel/s. Memory bandwidth is 1.79 TB/s versus 273.2 GB/s. The RTX PRO 6000 also has more shading units (24,064 versus 6,144), more texture mapping units (752 versus 384), more raster operation units (192 versus 48), more ray tracing cores (188 versus 48), and more tensor cores (752 versus 192). It runs at higher clocks: base 1590 MHz versus 741 MHz, boost 2617 MHz versus 2346 MHz, and memory 1750 MHz versus 1067 MHz.

The N1X 48SM wins in memory capacity with 128 GB versus 96 GB. It also wins on physical integration: it is an IGP with no power connectors and no slot width, whereas the RTX PRO 6000 is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width. The N1X draws no external power and requires no PSU recommendation, while the RTX PRO 6000 lists a 600 W TDP and a 1000 W suggested PSU. The N1X also has a smaller die at 382 mm² versus 750 mm², though the RTX PRO 6000 has a known transistor count of 92,200 million and a transistor density of 122.9M per mm², while the N1X's transistor count is unknown.

The display outputs differ as well. The N1X 48SM has a single HDMI output. The RTX PRO 6000 has four DisplayPort 2.1b outputs. For multi-monitor professional setups, the RTX PRO 6000 is the clear choice. For a single display on an integrated solution, the N1X suffices.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture and are fabricated by TSMC on a 5 nm process. The underlying chips, however, are different. The N1X 48SM uses the GB20B chip, while the RTX PRO 6000 Blackwell uses the GB202 chip. The N1X belongs to the Blackwell IGP (N1x) generation, and the RTX PRO 6000 belongs to the Blackwell PRO W (x000) generation.

The RTX PRO 6000's GB202 die measures 750 mm² and contains 92,200 million transistors, giving it a transistor density of 122.9M per mm². The N1X 48SM's GB20B die measures 382 mm², and its transistor count is unknown. The N1X die is nearly half the size of the RTX PRO 6000 die, which correlates with its lower shading unit count: 6,144 versus 24,064.

Core counts differ substantially. The N1X has 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The RTX PRO 6000 has 752 TMUs, 192 ROPs, 188 ray tracing cores, and 752 tensor cores. The RTX PRO 6000 has 1.96x the TMUs, 4x the ROPs, 3.92x the ray tracing cores, and 3.92x the tensor cores.

Memory architecture is fundamentally different. The N1X uses LPDDR5X on a 256-bit bus with 8.5 Gbps effective speed. The RTX PRO 6000 uses GDDR7 on a 512-bit bus with 28 Gbps effective speed. Both use a PCIe 5.0 x16 bus interface. The N1X has one HDMI output; the RTX PRO 6000 has four DisplayPort 2.1b outputs.

The N1X has no recorded DirectX, OpenGL, or Vulkan support. The RTX PRO 6000 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX PRO 6000 also has a predecessor listed as Workstation Ada, while the N1X has no predecessor. Both parts are currently Active in production.

Specification Differences

Clock speeds differ significantly. The N1X 48SM runs at a base clock of 741 MHz and a boost clock of 2346 MHz. The RTX PRO 6000 Blackwell runs at a base clock of 1590 MHz and a boost clock of 2617 MHz. Memory clocks are 1067 MHz for the N1X and 1750 MHz for the RTX PRO 6000.

Memory capacity and type are the most visible differences. The N1X has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The RTX PRO 6000 has 96 GB of GDDR7 on a 512-bit bus with 1.79 TB/s bandwidth.

Compute rates are as follows: the N1X produces 112.6 GPixel/s and 900.9 GTexel/s, while the RTX PRO 6000 produces 502.5 GPixel/s and 1,968.0 GTexel/s. FP32 and FP16 rates are identical within each card, at 28.83 TFLOPS for the N1X and 126.0 TFLOPS for the RTX PRO 6000.

Power and physical specifications differ entirely. The N1X is an IGP with no slot width, no power connectors, and no TDP recorded. The RTX PRO 6000 is a dual-slot card with a 600 W TDP, a single 16-pin power connector, and a 1000 W suggested PSU. Its dimensions are 304 mm by 137 mm by 40 mm.
