NVIDIA N1 16SM vs NVIDIA RTX 1000 Mobile Ada Generation Comparison

Where Each One Wins

The recorded data shows a split that depends entirely on the use case, as neither part in this comparison dominates the other across all measured dimensions. The NVIDIA RTX 1000 Mobile Ada Generation holds advantages in raw shader throughput, ray tracing hardware count, pixel processing, and API compatibility. The NVIDIA N1 16SM counters with a substantially larger memory pool, higher memory bandwidth, a wider bus, more texture units, and a newer PCIe interface.

For compute-heavy workloads that rely on FP32 or FP16 math, the RTX 1000 Mobile Ada Generation leads with 10.37 TFLOPS in both formats, compared to 9.609 TFLOPS for the N1 16SM. The difference is modest, roughly 0.76 TFLOPS, which translates to about 7.9% more floating-point throughput. The N1 16SM does not close this gap, but it does offer a 1:1 FP16 to FP32 ratio in both cases, so mixed-precision workloads will scale similarly on either part.

For memory-intensive tasks, the N1 16SM is the clear winner. It carries 128 GB of LPDDR5X memory on a 256 bit bus, yielding 273.2 GB/s of bandwidth. The RTX 1000 Mobile Ada Generation has 6 GB of GDDR6 on a 96 bit bus, yielding 192.0 GB/s. The N1 16SM offers over 21 times the capacity and 42.3% more bandwidth. Large dataset processing, model loading, or multi-scene rendering that exceeds 6 GB will only function on the N1 16SM.

For texture-heavy graphics work, the N1 16SM has 128 TMUs against 80 TMUs on the RTX 1000 Mobile Ada Generation. Its texture rate is 300.3 GTexel/s compared to 162.0 GTexel/s, meaning the N1 16SM processes textures at 85.4% higher throughput. However, the RTX 1000 Mobile Ada Generation has 48 ROPs versus 24 ROPs, giving it a pixel rate of 97.20 GPixel/s versus 56.30 GPixel/s, a 72.6% advantage in pixel output.

Software ecosystem compatibility also separates the two. The RTX 1000 Mobile Ada Generation supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists all three APIs as N/A, which means applications relying on those graphics APIs cannot use it in the same manner. The RTX 1000 Mobile Ada Generation also has 20 RT cores and 80 tensor cores, while the N1 16SM has 16 RT cores and 64 tensor cores. The N1 16SM does connect via PCIe 5.0 x16, while the RTX 1000 Mobile Ada Generation uses PCIe 4.0 x8, so the N1 16SM has a wider and newer interface for data movement.

The Verdict

The data indicates that the NVIDIA RTX 1000 Mobile Ada Generation is the stronger choice for standard graphics workloads. It has higher FP32 and FP16 compute at 10.37 TFLOPS, more RT cores at 20, more tensor cores at 80, and more shading units at 2560. It also has 48 ROPs, giving it a pixel rate of 97.20 GPixel/s, which is 72.6% higher than the N1 16SM. Its support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 means it can run modern graphics APIs, while the N1 16SM lists these as N/A. The TDP of 35 W is recorded, and the release date of 2024-02-25 places it earlier in the product cycle.

The NVIDIA N1 16SM is the better option for memory-bound or texture-bound tasks. It has 128 GB of memory, which is 21.3 times the capacity of the RTX 1000 Mobile Ada Generation. Its bandwidth of 273.2 GB/s is 42.3% higher. Its texture rate of 300.3 GTexel/s is 85.4% higher, driven by 128 TMUs. It also uses PCIe 5.0 x16, which is a newer and wider interface than PCIe 4.0 x8. The release date of 2026-05-31 indicates a newer product.

The RTX 1000 Mobile Ada Generation wins on per-core compute density and graphics feature support. The N1 16SM wins on memory capacity, memory bandwidth, texture throughput, and interface generation. Both have a percentileVsAllGpus of 50, and both have an avgBenchmarkScore of 0, so the database does not rank one above the other in overall performance. The choice depends on whether the workload is limited by memory capacity, texture processing, or by pixel output and API compatibility. The RTX 1000 Mobile Ada Generation is the only one of the two that can run standard graphics APIs, and the N1 16SM is the only one that can handle datasets larger than 6 GB.
