The N1 16SM has no nearest rivals listed in the database and no head-to-head benchmark comparisons against the RTX PRO 5000 Blackwell. The wins counter shows zero for both items, reflecting the lack of direct comparative test data. Any performance assessment of the N1 16SM must rely on its architectural and specification profile rather than measured scores. The RTX PRO 5000 Blackwell, by contrast, has a clear performance footprint across three distinct benchmark types, all indicating strong compute capabilities.

Where Each One Wins

The RTX PRO 5000 Blackwell wins in every measured benchmark category because the N1 16SM has no recorded benchmark results. In compute workloads, the Geekbench OpenCL score of 254,116 and Vulkan score of 282,631 indicate substantial throughput for general-purpose and graphics API workloads. The 3DMark Steel Nomad DX12 result of 9,579.5 points confirms DirectX 12 rendering capability. The N1 16SM, with its IGP form factor and no API support listed for DirectX, OpenGL, or Vulkan, appears oriented toward a different use case entirely.

The N1 16SM wins in memory capacity with 128 GB of LPDDR5X, which is 80 GB more than the RTX PRO 5000 Blackwell's 48 GB of GDDR7. This capacity advantage suggests the N1 16SM targets large in-memory data workloads, potentially for AI inference or data processing where model sizes exceed the VRAM of discrete cards. The N1 16SM also uses a 5 nm process node at TSMC, identical to the RTX PRO 5000 Blackwell, but its die size of 382 mm² is considerably smaller than the 750 mm² GB202 die.

The RTX PRO 5000 Blackwell wins on bandwidth decisively. Its memory bandwidth of 1.34 TB/s is nearly five times the N1 16SM's 273.2 GB/s. The 384 bit memory bus versus 256 bit, combined with GDDR7 at 28 Gbps effective versus LPDDR5X at 8.5 Gbps effective, explains this gap. For memory-bound workloads, the RTX PRO 5000 Blackwell moves data much faster per second, even though the N1 16SM holds more total data.

The RTX PRO 5000 Blackwell wins on raw compute throughput. Its FP32 performance of 66.94 TFLOPS dwarfs the N1 16SM's 9.609 TFLOPS, a difference of approximately 6.97 times. The FP16 performance follows the same 1:1 ratio for both, with the RTX PRO 5000 Blackwell delivering 66.94 TFLOPS against the N1 16SM's 9.609 TFLOPS. Texture rate shows 1,045.9 GTexel/s for the RTX PRO 5000 Blackwell versus 300.3 GTexel/s, and pixel rate of 380.3 GPixel/s versus 56.30 GPixel/s.

Architecture Differences

Both GPUs use the Blackwell 2.0 architecture and are manufactured by NVIDIA at TSMC on a 5 nm process. The N1 16SM uses the GB20B chip and belongs to the Blackwell IGP (N1x) generation. The RTX PRO 5000 Blackwell uses the GB202 chip and belongs to the Blackwell PRO W (x000) generation. The chip difference is substantial: GB202 contains 92,200 million transistors on a 750 mm² die, while the GB20B's transistor count is listed as unknown on a 382 mm² die. The transistor density for GB202 is 122.9 million transistors per square millimeter, while the N1 16SM has no recorded density figure.

The N1 16SM carries 2,048 shading units, 128 texture mapping units, and 24 raster output units. The RTX PRO 5000 Blackwell carries 14,080 shading units, 440 TMUs, and 160 ROPs. This represents a 6.875 times advantage in shading units, a 3.4375 times advantage in TMUs, and a 6.667 times advantage in ROPs. Ray tracing cores number 16 for the N1 16SM versus 110 for the RTX PRO 5000 Blackwell. Tensor cores total 64 versus 440. The RTX PRO 5000 Blackwell's larger compute configuration aligns with its discrete, dual-slot form factor and 300 W TDP, while the N1 16SM is an IGP with no power connectors and no recorded TDP.

The RTX PRO 5000 Blackwell supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists N/A for all three APIs.
