Analysis: NVIDIA N1X 40SM vs NVIDIA RTX 500 Mobile Ada Generation
The Verdict
The data presents two fundamentally different NVIDIA designs with no direct benchmark overlap recorded. The N1X 40SM is a Blackwell 2.0 IGP with an enormous 128 GB memory pool and 5120 shading units, while the RTX 500 Mobile Ada Generation is a compact AD107 part with 2048 shading units and 4 GB of GDDR6. The recorded specifications indicate the N1X 40SM delivers roughly three times the FP32 throughput (24.02 TFLOPS vs 8.294 TFLOPS), nearly double the texture rate (750.7 GTexel/s vs 129.6 GTexel/s), and more than double the memory bandwidth (273.2 GB/s vs 128.0 GB/s). The RTX 500 counters with a higher base clock (1485 MHz vs 741 MHz), full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and a known 35 W TDP. Buyers needing massive memory capacity and raw compute should select the N1X 40SM. Users requiring documented software compatibility and a mobile-friendly power envelope should select the RTX 500 Mobile Ada Generation.

The N1X 40SM is built on the Blackwell 2.0 architecture using the GB20B chip, fabricated on a 5 nm process at TSMC. Its die size is 382 mm², and it belongs to the Blackwell IGP (N1x) generation. The architecture supports 40 ray tracing cores and 160 tensor cores, which is a substantial increase over the RTX 500's 16 RT cores and 64 tensor cores. The N1X 40SM's memory subsystem uses LPDDR5X at 1067 MHz with an 8.5 Gbps effective rate, paired with a 256-bit bus. The pixel rate is 93.84 GPixel/s, and the texture rate is 750.7 GTexel/s.
The RTX 500 Mobile Ada Generation uses the Ada Lovelace architecture with the AD107 chip, also on a 5 nm TSMC process. Its die size is 159 mm², and it contains 18,900 million transistors with a transistor density of 118.9M per mm². The memory runs at 2000 MHz with a 16 Gbps effective rate over a 64-bit bus. The pixel rate is 64.80 GPixel/s, and the texture rate is 129.6 GTexel/s. The RTX 500 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the N1X 40SM lists no API support in the database. The RTX 500's predecessor is Ampere-MW and its successor is Blackwell-MW, placing it in the Ada-MW (x000A) generation.
Specification Differences
The two GPUs differ across nearly every recorded specification. The N1X 40SM has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The RTX 500 Mobile Ada Generation has 2048 shading units, 64 TMUs, 32 ROPs, 16 RT cores, and 64 tensor cores. The base clock is 741 MHz for the N1X 40SM versus 1485 MHz for the RTX 500, while the boost clock is 2346 MHz versus 2025 MHz. Memory size is 128 GB LPDDR5X versus 4 GB GDDR6, with bus widths of 256 bit versus 64 bit. Bandwidth is 273.2 GB/s versus 128.0 GB/s.
FP32 compute is 24.02 TFLOPS for the N1X 40SM and 8.294 TFLOPS for the RTX 500, with FP16 matching at a 1:1 ratio for both. Pixel rate is 93.84 GPixel/s versus 64.80 GPixel/s, and texture rate is 750.7 GTexel/s versus 129.6 GTexel/s. The TDP is unknown for the N1X 40SM, while the RTX 500 is rated at 35 W. The bus interface is PCIe 5.0 x16 for the N1X 40SM and PCIe 4.0 x8 for the RTX 500. Display outputs are 1x HDMI for the N1X 40SM and Portable Device Dependent for the RTX 500. The die size is 382 mm² versus 159 mm², and the transistor count is unknown for the N1X 40SM versus 18,900 million for the RTX 500. Both use a 5 nm TSMC process, and both are IGP slot width with no power connectors.
Head-to-Head Benchmarks
The database records no head-to-head benchmark results for these two GPUs, and neither has an average benchmark score or a percentile ranking beyond the shared 50th percentile versus all GPUs. The wins are zero for both sides in the recorded head-to-head category. However, the specification data provides a clear comparative picture for compute-oriented workloads. The N1X 40SM delivers 24.02 TFLOPS of FP32 performance, which is 2.9 times the RTX 500's 8.294 TFLOPS. In texture throughput, the N1X 40SM's 750.7 GTexel/s is 5.8 times the RTX 500's 129.6 GTexel/s. The pixel rate advantage is 93.84 GPixel/s versus 64.80 GPixel/s, a 1.45 times margin.
Memory bandwidth favors the N1X 40SM at 273.2 GB/s versus 128.0 GB/s, a 2.13 times advantage. The RTX 500 Mobile Ada Generation counters with a 2.0 times higher base clock (1485 MHz vs 741 MHz), though its boost clock is 13.7% lower (2025 MHz vs 2346 MHz). The RTX 500 also has a smaller die (159 mm² vs 382 mm²) and a known 35 W TDP, whereas the N1X 40SM's TDP is unknown. The RTX 500's 18,900 million transistors on a smaller die yield a transistor density of 118.9M per mm², a figure not recorded for the N1X 40SM.
Where Each One Wins
The N1X 40SM wins in raw compute throughput, memory capacity, and memory bandwidth. Its 5120 shading units and 160 tensor cores position it for heavy parallel workloads, and its 128 GB memory pool is 32 times larger than the RTX 500's 4 GB. The 256-bit bus provides 273.2 GB/s, which is more than double the RTX 500's 128.0 GB/s. The 40 RT cores versus 16 RT cores and 40 ROPs versus 32 ROPs further extend its lead in geometry processing and pixel output. The PCIe 5.0 x16 interface gives it twice the bus width of the RTX 500's PCIe 4.0 x8.
The RTX 500 Mobile Ada Generation wins in software compatibility and power efficiency. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1X 40SM lists N/A for all three APIs. Its 35 W TDP is explicitly recorded, offering a known power envelope for mobile integration. The higher base clock of 1485 MHz suggests better sustained low-load operation, and the smaller 159 mm² die with 18,900 million transistors implies a denser, more compact implementation. The RTX 500's release date of 2024-02-25 predates the N1X 40SM's 2026-05-31, and its predecessor and successor are documented within the Ada-MW lineage.
For users whose workloads require the largest possible memory footprint and maximum FP32 or texture throughput, the N1X 40SM is the only choice in this comparison. For users who need confirmed API support and a mobile-appropriate power draw, the RTX 500 Mobile Ada Generation holds the advantage. The shared 50th percentile ranking and zero recorded benchmark scores mean neither GPU demonstrates a measured performance win in the database; the decision rests entirely on the specification differences above.
