NVIDIA N1X 48SM vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the NVIDIA N1X 48SM and the NVIDIA RTX 5000 Mobile Ada Generation. The database contains only a single 3DMark Steel Nomad DX12 score for the RTX 5000 Mobile Ada Generation: 3596 points. That result places the mobile GPU at the 21st percentile among all GPUs in the database. The nearest rivals in the recorded data are the NVIDIA GeForce GT 545 at 3594 points (a 0.1% difference), the NVIDIA GeForce GT 735M at 3616 points (0.6% ahead), the NVIDIA GeForce GTX 1050 at 3629 points (0.9% ahead), and the AMD Radeon HD 6770 at 3649 points (1.5% ahead). These margins are tiny, which suggests the RTX 5000 Mobile Ada Generation sits in a very crowded performance band where small clock or driver variations can flip the ordering.

The N1X 48SM has no benchmark entries in the database. Its average benchmark score is recorded as 0, and its percentile versus all GPUs is 50. Without any measured workload results, the database cannot confirm how the N1X 48SM performs in real applications. The RTX 5000 Mobile Ada Generation has a measurable score, but the N1X 48SM does not. This asymmetry means any comparison of raw performance relies on architectural specifications rather than observed benchmark data.

The FP32 compute figures provide a theoretical comparison. The RTX 5000 Mobile Ada Generation delivers 41.15 TFLOPS, while the N1X 48SM delivers 28.83 TFLOPS. That is a 42.7% advantage for the mobile Ada part in raw single-precision throughput. The FP16 figures are identical to the FP32 figures for both parts (1:1 ratio), so the same proportional gap applies to half-precision work. Pixel rate favors the RTX 5000 Mobile Ada Generation at 236.9 GPixel/s versus 112.6 GPixel/s, a 110.4% advantage. Texture rate tells a different story: the N1X 48SM reaches 900.9 GTexel/s, while the RTX 5000 Mobile Ada Generation reaches 643.0 GTexel/s, giving the N1X 48SM a 40.1% lead. Memory bandwidth also splits the two: the RTX 5000 Mobile Ada Generation has 576.0 GB/s, the N1X 48SM has 273.2 GB/s, a 110.8% advantage for the mobile part.

Architecture Differences

The two GPUs come from different NVIDIA architectures. The N1X 48SM uses the GB20B chip built on Blackwell 2.0 architecture, while the RTX 5000 Mobile Ada Generation uses the AD103 chip built on Ada Lovelace architecture. Both are manufactured on a 5 nm process at TSMC, but the die sizes are close: 382 mm² for the N1X 48SM and 379 mm² for the RTX 5000 Mobile Ada Generation. The transistor density for the Ada part is recorded as 121.1 million transistors per mm², giving a total of 45,900 million transistors. The N1X 48SM transistor count is unknown.

The N1X 48SM belongs to the Blackwell IGP (N1x) generation with a release date of May 31, 2026. The RTX 5000 Mobile Ada Generation belongs to the Ada-MW generation with a release date of March 20, 2023. The mobile Ada part has a predecessor listed as Ampere-MW and a successor listed as Blackwell-MW. The N1X 48SM lists no predecessor or successor.

Core counts differ substantially. The N1X 48SM has 6144 shading units, 384 texture mapping units, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The RTX 5000 Mobile Ada Generation has 9728 shading units, 304 TMUs, 112 ROPs, 76 RT cores, and 304 tensor cores. The Ada part leads in shading units, ROPs, RT cores, and tensor cores. The N1X 48SM leads in TMUs, with 384 versus 304.

The N1X 48SM uses a PCIe 5.0 x16 bus interface, while the RTX 5000 Mobile Ada Generation uses PCIe 4.0 x16. The display output for the N1X 48SM is listed as 1x HDMI, while the mobile Ada part lists "Portable Device Dependent". Neither uses power connectors, and both are classified as IGP slot width. The N1X 48SM operates at base 741 MHz and boost 2346 MHz, with memory at 1067 MHz (8.5 Gbps effective). The RTX 5000 Mobile Ada Generation runs at base 1425 MHz and boost 2115 MHz, with memory at 2250 MHz (18 Gbps effective). The N1X 48SM has a higher boost clock, but the Ada part has a much higher base clock and faster memory.

The Verdict

The database does not contain any benchmark results for the N1X 48SM, so a direct performance verdict cannot be drawn from measured workloads. The RTX 5000 Mobile Ada Generation has a single recorded 3DMark Steel Nomad DX12 score of 3596, placing it at the 21st percentile among all GPUs. That score is nearly identical to the GeForce GT 545, GT 735M, GTX 1050, and Radeon HD 6770, all within 1.5% in either direction. This indicates the mobile Ada part occupies a modest performance tier, not a flagship position.

From a specification standpoint, the RTX 5000 Mobile Ada Generation holds clear advantages in FP32 throughput (41.15 TFLOPS versus 28.83 TFLOPS), pixel rate (236.9 GPixel/s versus 112.6 GPixel/s), memory bandwidth (576.0 GB/s versus 273.2 GB/s), shading units (9728 versus 6144), RT cores (76 versus 48), and tensor cores (304 versus 192). The N1X 48SM counters with a higher texture rate (900.9 GTexel/s versus 643.0 GTexel/s), more TMUs (384 versus 304), a higher boost clock (2346 MHz versus 2115 MHz), and far more memory capacity (128 GB versus 16 GB).

The N1X 48SM also carries a PCIe 5.0 interface versus PCIe 4.0 on the mobile Ada part, and it has a newer release date (May 31, 2026 versus March 20, 2023). However, the N1X 48SM lists no DirectX, OpenGL, or Vulkan support in the database, which would limit its use in conventional gaming or graphics applications. The RTX 5000 Mobile Ada Generation supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it the only one of the two with recorded API compatibility.

For users who need measured benchmark confidence, the RTX 5000 Mobile Ada Generation is the only part with a database score. For users who prioritize raw memory capacity, texture throughput, or a newer PCIe interface, the N1X 48SM offers those features on paper. The 128 GB memory pool of the N1X 48SM is eight times larger than the 16 GB on the mobile Ada part, which could matter for datasets that exceed 16 GB. But the mobile Ada part has more than double the memory bandwidth, which often matters more for sustained throughput.

Where Each One Wins

The RTX 5000 Mobile Ada Generation wins in compute-heavy workloads. Its FP32 throughput of 41.15 TFLOPS exceeds the N1X 48SM by 42.7%, which directly benefits shader-bound rendering, physics simulations, and general GPU compute. The pixel rate advantage (236.9 GPixel/s versus 112.6 GPixel/s) gives it a clear lead in fill-rate-limited scenarios such as high-resolution rasterization with heavy overdraw. Memory bandwidth of 576.0 GB/s versus 273.2 GB/s means the mobile Ada part can feed data to its 9728 shading units faster, reducing stalls in bandwidth-sensitive algorithms. The mobile Ada part also has full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it the only one of the two with recorded compatibility for modern graphics APIs.

The N1X 48SM wins in texture-centric operations. Its texture rate of 900.9 GTexel/s is 40.1% higher than the mobile Ada part, and its 384 TMUs outnumber the 304 TMUs on the RTX 5000 Mobile Ada Generation. This gives the N1X 48SM an edge in workloads that repeatedly sample textures, such as certain procedural generation tasks or texture-heavy rendering pipelines. The 128 GB memory capacity is eight times the 16 GB of the mobile Ada part, which matters for workloads that must hold very large datasets entirely in GPU memory. The N1X 48SM also has a faster boost clock (2346 MHz versus 2115 MHz), which can help in lightly threaded or latency-sensitive operations. The PCIe 5.0 x16 interface provides double the signaling rate of the PCIe 4.0 x16 interface on the mobile Ada part, reducing transfer times for data that moves frequently between CPU and GPU memory.

For ray tracing, the mobile Ada part has 76 RT cores versus 48 on the N1X 48SM, a 58.3% advantage. For tensor operations, the mobile Ada part has 304 tensor cores versus 192, a 58.3% advantage as well. These gaps mirror the shading unit difference, so the RTX 5000 Mobile Ada Generation is the stronger choice for AI inference and ray-traced rendering. The N1X 48SM has no recorded DirectX support, which places its ray tracing and tensor capabilities outside of standard gaming or D3D workloads. The mobile Ada part, by contrast, has a measured 3DMark Steel Nomad DX12 score of 3596, confirming it can complete at least one modern DX12 benchmark. The N1X 48SM has no such confirmation.

The TDP figures also separate the two. The RTX 5000 Mobile Ada Generation draws 120 W, while the N1X 48SM TDP is unknown. Both are IGP-class with no power connectors, but the mobile Ada part has a documented power envelope. The N1X 48SM, with its later release date and PCIe 5.0 support, appears aimed at a different system role, possibly an integrated GPU for large-memory compute rather than a discrete mobile graphics solution.
