Architecture Differences

The two GPUs share the same Blackwell 2.0 architecture and 5 nm TSMC process node, but their implementations diverge sharply. The N1X 40SM is built on the GB20B chip with a die size of 382 mm², while the RTX PRO 5000 Blackwell uses the GB202 chip with a die size of 750 mm². Transistor counts differ dramatically: the N1X 40SM has an unknown transistor count, whereas the RTX PRO 5000 Blackwell contains 92,200 million transistors with a density of 122.9M per mm².

The N1X 40SM integrates 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The RTX PRO 5000 Blackwell scales to 14080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. This represents a 2.75x increase in shading units and tensor cores, a 2.75x increase in RT cores, and a 4x increase in ROPs.

Memory architecture also differs fundamentally. The N1X 40SM uses 128 GB of LPDDR5X with a 256-bit bus, delivering 273.2 GB/s. The RTX PRO 5000 Blackwell uses 48 GB of GDDR7 with a 384-bit bus, delivering 1.34 TB/s, which is roughly 4.9x the bandwidth of the IGP. Clock behavior differs as well: the N1X 40SM has a base clock of 741 MHz and boost of 2346 MHz, while the RTX PRO 5000 Blackwell starts at 1740 MHz base and boosts to 2377 MHz.

The N1X 40SM reports no API support for DirectX, OpenGL, or Vulkan, while the RTX PRO 5000 Blackwell supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the N1X 40SM has a single HDMI, while the RTX PRO 5000 Blackwell provides 4x DisplayPort 2.1b. The RTX PRO 5000 Blackwell is a dual-slot card measuring 267 mm by 111 mm by 40 mm, while the N1X 40SM is an IGP with no dimensions listed.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the N1X 40SM and the RTX PRO 5000 Blackwell. The N1X 40SM has no benchmark scores listed and no average score, while the RTX PRO 5000 Blackwell has three recorded benchmarks and an average score of 182109.

The RTX PRO 5000 Blackwell's Geekbench Vulkan score of 282631 exceeds its OpenCL score of 254116 by approximately 11.2%, indicating strong compute performance across both APIs. The 3DMark Steel Nomad DX12 score of 9579.5 reflects a dedicated graphics workload, which the N1X 40SM cannot match given its absence of recorded benchmarks and API support.

The RTX PRO 5000 Blackwell's nearest rivals provide context for its positioning. The A100 SXM4 80 GB scores 183725, which is 0.9% higher than the RTX PRO 5000's average, and the RTX 5000 Ada Generation scores 184664, 1.4% higher. The GeForce RTX 4090 D scores 178050, which is 2.3% lower, and the A100 SXM4 40 GB scores 187147, 2.7% higher. These deltas show the RTX PRO 5000 Blackwell sits within a narrow performance band around its closest competitors, roughly 2.3% above the RTX 4090 D and within 2.7% of the A100 SXM4 40 GB.

Given the N1X 40SM has no benchmark scores, the data cannot establish a quantitative head-to-head comparison. The percentile rankings offer a relative signal: the N1X 40SM at the 50th percentile versus the RTX PRO 5000 Blackwell at the 98th percentile. The gap between these positions indicates a substantial performance separation, though the absence of direct scores for the N1X 40SM prevents precise deltas.

Where Each One Wins

The data shows the RTX PRO 5000 Blackwell wins across every measured performance category. Its FP32 compute of 66.94 TFLOPS is 2.79x the N1X 40SM's 24.02 TFLOPS. Its pixel rate of 380.3 GPixel/s is 4.05x the N1X 40SM's 93.84 GPixel/s. Its texture rate of 1,045.9 GTexel/s is 1.39x the N1X 40SM's 750.7 GTexel/s. Memory bandwidth favors the RTX PRO 5000 Blackwell at 1.34 TB/s versus 273.2 GB/s, a 4.9x advantage.

The N1X 40SM wins in memory capacity, offering 128 GB versus 48 GB. The IGP also holds advantages in physical footprint, requiring no slot width, no power connectors, and no suggested PSU. Its unknown TDP and IGP form factor point to a low-power integrated solution, while the RTX PRO 5000 Blackwell demands a 300 W TDP and a 700 W PSU.

The RTX PRO 5000 Blackwell supports full API stacks (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), while the N1X 40SM lists N/A for all three. Display output also favors the discrete card with 4x DisplayPort 2.1b versus a single HDMI.

For compute workloads, the RTX PRO 5000 Blackwell's Geekbench OpenCL score of 254116 and Vulkan score of 282631 demonstrate strong general-purpose performance. The 3DMark Steel Nomad DX12 score of 9579.5 shows dedicated graphics capability. The N1X 40SM has no recorded scores, so its wins are structural: capacity, integration, and minimal power requirements.

The Verdict

The benchmark data clearly indicates the RTX PRO 5000 Blackwell as the superior performer. It holds the 98th percentile versus the N1X 40SM's 50th, has an average score of 182109 versus 0, and outperforms the IGP in every compute metric. The FP32 gap of 66.94 TFLOPS versus 24.02 TFLOPS and the pixel rate gap of 380.3 GPixel/s versus 93.84 GPixel/s confirm a wide performance margin. For users needing maximum compute, graphics, and memory bandwidth, the RTX PRO 5000 Blackwell is the data-supported choice.

The N1X 40SM serves a different role. Its 128 GB capacity exceeds the RTX PRO 5000 Blackwell's 48 GB, and its IGP form factor with no power connectors suits integrated systems where discrete cards cannot fit. The unknown TDP suggests minimal power draw, though the database does not quantify this. For applications prioritizing memory capacity over bandwidth and requiring a compact, integrated solution, the N1X 40SM has a structural advantage.

The RTX PRO 5000 Blackwell's nearest rivals show it competes closely with established workstation and data center parts. It sits within 2.7% of the A100 SXM4 40 GB and within 0.9% of the A100 SXM4 80 GB, while leading the RTX 4090 D by 2.3%. This positioning indicates a workstation GPU that matches top-tier compute accelerators in average score.

The release dates add context: the RTX PRO 5000 Blackwell launched on 2025-03-17 with a launch MSRP of 5,099 USD, while the N1X 40SM's release date is 2026-05-31. The N1X 40SM represents a later integrated design, but the data shows no benchmark evidence to suggest it closes the performance gap. The RTX PRO 5000 Blackwell remains the pick for measured performance, while the N1X 40SM suits integrated environments where its capacity and form factor are the deciding factors.
