NVIDIA N1X 40SM vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores between the NVIDIA N1X 40SM and the NVIDIA RTX PRO 2000 Blackwell. However, the RTX PRO 2000 Blackwell has recorded benchmark data across multiple tests, while the N1X 40SM has no benchmark entries in the database. This means the comparison below relies on the RTX PRO 2000 Blackwell’s measured results and the architectural specifications of both parts, rather than a shared test suite.

The RTX PRO 2000 Blackwell’s recorded scores include a 3DMark Steel Nomad DX12 result of 2374.5, Geekbench OpenCL of 106087, Geekbench Vulkan of 113865, PassMark G3D of 20049, and PassMark GPU Compute of 8396. Its average benchmark score sits at 25269, placing it in the 70th percentile among all GPUs in the database. The nearest rivals show a tight cluster: the AMD Radeon RX 6700M scores 25633 (1.4% higher), the AMD Radeon Pro W5700 scores 25726 (1.8% higher), and the NVIDIA GeForce RTX 3080 Ti Mobile scores 25740 (1.8% higher). The NVIDIA RTX A5000 Mobile trails at 24763, which is 2% lower than the RTX PRO 2000 Blackwell.

Because the N1X 40SM has no benchmark scores, the database cannot show it winning any test. The wins count is zero for the N1X 40SM and zero for the RTX PRO 2000 Blackwell in direct head-to-head comparisons. What the data does show is that the RTX PRO 2000 Blackwell is a functional, measurable part with scores in the upper-middle range of the database, while the N1X 40SM remains unmeasured, so any performance inference must be drawn from its specifications alone.

The RTX PRO 2000 Blackwell’s PassMark results show a pattern: DirectX 9 scores 241, DirectX 10 scores 122, DirectX 11 scores 174, and DirectX 12 scores 80. The DirectX 9 result is roughly three times the DirectX 12 result, which indicates the card’s strength in legacy API workloads. The PassMark G2D score of 1303 is modest, while the G3D score of 20049 is the primary gaming-oriented metric. The compute score of 8396 is less than half the G3D score, suggesting compute-heavy tasks are not the card’s strongest area relative to graphics. The Geekbench results are more balanced, with OpenCL at 106087 and Vulkan at 113865, a difference of about 7%, favoring Vulkan.

The N1X 40SM’s FP32 throughput is 24.02 TFLOPS, which is 41% higher than the RTX PRO 2000 Blackwell’s 17.03 TFLOPS. That is a substantial raw compute advantage, but it is unverified by any benchmark. The RTX PRO 2000 Blackwell’s nearest rival data shows it is within 2% of three different GPUs, meaning its performance class is well established. The N1X 40SM, by contrast, has no rivals listed and no percentile beyond the default 50th, which reflects the absence of measurement data.

Architecture Differences

Both GPUs are built on the Blackwell 2.0 architecture and use TSMC’s 5 nm process node. The N1X 40SM uses the GB20B chip, while the RTX PRO 2000 Blackwell uses the GB206 chip. The N1X 40SM is classified as a Blackwell IGP (N1x) generation part, meaning it is an integrated graphics processor, whereas the RTX PRO 2000 Blackwell is from the Blackwell PRO W (x000) generation, a discrete workstation card.

The N1X 40SM has a die size of 382 mm², which is more than double the RTX PRO 2000 Blackwell’s 181 mm². The RTX PRO 2000 Blackwell lists its transistor count at 21,900 million and a transistor density of 121.0M per mm². The N1X 40SM’s transistor count is listed as unknown, so no direct comparison of transistor density is possible. The larger die on the N1X 40SM suggests a more complex design, but the transistor count data is missing.

The N1X 40SM carries 5120 shading units, 320 texture mapping units, 40 ROPs, 40 ray tracing cores, and 160 tensor cores. The RTX PRO 2000 Blackwell has 4352 shading units, 136 TMUs, 48 ROPs, 34 RT cores, and 136 tensor cores. The N1X 40SM has 18% more shading units, 135% more TMUs, 18% more RT cores, and 18% more tensor cores, while the RTX PRO 2000 Blackwell has 20% more ROPs. The shading unit and tensor core count differences are modest, but the TMU gap is large, which directly affects texture fill rate.

The N1X 40SM’s texture rate is 750.7 GTexel/s versus the RTX PRO 2000 Blackwell’s 266.2 GTexel/s, a 182% advantage for the N1X 40SM. Pixel rates are nearly identical: 93.84 GPixel/s for the N1X 40SM and 93.94 GPixel/s for the RTX PRO 2000 Blackwell. The N1X 40SM’s FP16 throughput matches its FP32 at 24.02 TFLOPS (1:1), and the RTX PRO 2000 Blackwell does the same at 17.03 TFLOPS (1:1), so neither card has a consumer-style FP16 penalty.

The RTX PRO 2000 Blackwell supports a full API stack: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists N/A for all three APIs, which is consistent with an IGP that may rely on system-level graphics paths rather than a dedicated API implementation. The N1X 40SM has one HDMI output, while the RTX PRO 2000 Blackwell has four mini-DisplayPort 2.1b outputs. The RTX PRO 2000 Blackwell is dual-slot with dimensions of 167 mm length, 69 mm height, and 20 mm width. The N1X 40SM is an IGP with no slot width, no power connectors, and no listed dimensions.

The clock behavior also differs. The N1X 40SM has a base clock of 741 MHz and a boost clock of 2346 MHz. The RTX PRO 2000 Blackwell has a base clock of 982 MHz and a boost clock of 1957 MHz. The N1X 40SM starts lower but boosts 20% higher, while the RTX PRO 2000 Blackwell has a higher base but a lower ceiling. Memory clocks differ as well: the N1X 40SM runs at 1067 MHz with 8.5 Gbps effective, and the RTX PRO 2000 Blackwell runs at 1125 MHz with 18 Gbps effective. The RTX PRO 2000 Blackwell’s memory is GDDR7, while the N1X 40SM uses LPDDR5X.

Release dates differ: the N1X 40SM is dated 2026-05-31, the RTX PRO 2000 Blackwell is dated 2025-08-10. The RTX PRO 2000 Blackwell has a predecessor listed as Workstation Ada; the N1X 40SM has no predecessor or successor. Both are marked as Active production status.

Where Each One Wins

The N1X 40SM wins on raw compute metrics from the specification sheet. Its FP32 throughput of 24.02 TFLOPS is the highest figure in either card’s data. Its texture rate of 750.7 GTexel/s is more than 2.8 times the RTX PRO 2000 Blackwell’s 266.2 GTexel/s. The 5120 shading units and 320 TMUs give it a clear advantage in workloads that scale with shader count and texture fetch rate. The 128 GB of LPDDR5X memory on a 256-bit bus provides far more capacity, though its 273.2 GB/s bandwidth is actually 5% lower than the RTX PRO 2000 Blackwell’s 288.0 GB/s. The N1X 40SM also has 160 tensor cores versus 136, which matters for AI inference if the software can reach those cores. The PCIe 5.0 x16 interface gives it double the lane width of the RTX PRO 2000 Blackwell’s x8 link.

The RTX PRO 2000 Blackwell wins on measured performance, power efficiency, and feature completeness. Its average benchmark score of 25269 places it in the 70th percentile of all GPUs in the database, while the N1X 40SM has no score. The RTX PRO 2000 Blackwell’s 70 W TDP is the only power figure in the data, and it is very low for a discrete card. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which means it can run modern graphics APIs directly. The N1X 40SM lists N/A for all APIs, making its software compatibility unknown. The RTX PRO 2000 Blackwell’s four mini-DisplayPort 2.1b outputs support multi-monitor setups, whereas the N1X 40SM has a single HDMI. The RTX PRO 2000 Blackwell’s memory bandwidth is 288.0 GB/s, which is higher than the N1X 40SM’s 273.2 GB/s despite the narrower 128-bit bus, because GDDR7 runs at a higher effective speed.

For pixel fill, the two are effectively tied: 93.84 GPixel/s versus 93.94 GPixel/s. That means neither card has a meaningful ROP throughput advantage. The RTX PRO 2000 Blackwell’s higher base clock of 982 MHz versus 741 MHz suggests better sustained performance at low power, while the N1X 40SM’s higher boost clock of 2346 MHz versus 1957 MHz gives it a higher peak in short bursts.

The Verdict

The data shows two very different products. The N1X 40SM is an integrated GPU with a massive memory pool (128 GB), a large die (382 mm²), and a compute-heavy specification set. It has no benchmark scores, no API support listed, and no power rating, so its real-world behavior is unverified. The RTX PRO 2000 Blackwell is a discrete workstation card with measured scores, a 70 W TDP, a 250 W suggested PSU, and full API support. Its average benchmark score of 25269 and 70th percentile ranking show it is a mid-to-upper tier performer, sitting within 2% of several established GPUs.

Who should pick the N1X 40SM? A user who needs extremely high FP32 throughput (24.02 TFLOPS), a very high texture rate (750.7 GTexel/s), and 128 GB of memory capacity. The data cannot confirm whether that compute translates into real application performance, but the specification sheet points to a part designed for large-memory compute loads, not for gaming or workstation graphics with API-level features. The PCIe 5.0 x16 interface and 256-bit LPDDR5X memory suggest a server or integrated-system role where memory capacity matters more than bandwidth.

Who should pick the RTX PRO 2000 Blackwell? A user who needs a known quantity: a GPU with a measured 3DMark Steel Nomad score of 2374.5, Geekbench Vulkan score of 113865, and PassMark G3D score of 20049. The 70 W TDP makes it easy to power with a 250 W PSU, and the four mini-DisplayPort outputs support multi-display professional work. Its DirectX 12 Ultimate and Vulkan 1.4 support means modern software will run without translation layers. The nearest rivals show it trades blows with the RX 6700M, W5700, and RTX 3080 Ti Mobile, all within 1.8% of its score, so buyers can expect performance in that class.

The database cannot declare a winner because the N1X 40SM has no measured results. The only fair statement is that the RTX PRO 2000 Blackwell is a verified, benchmarked part with a clear performance position, while the N1X 40SM is a specification-only entry whose actual throughput remains unrecorded. For any workload that requires known API support, measured scores, or low power draw, the RTX PRO 2000 Blackwell is the only one of the two with data to back it. For raw compute numbers on paper, the N1X 40SM leads in FP32, texture rate, shading units, and memory capacity, but none of that is confirmed by a single recorded test.
