NVIDIA N1X 48SM vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for the NVIDIA N1X 48SM against the NVIDIA RTX 2000 Mobile Ada Generation. Both entries list empty benchmark arrays and zero wins in the head-to-head comparison. This means the database currently holds no measured performance scores that would allow a direct numerical comparison between the two parts.

The absence of benchmark data does not prevent a structural comparison, however. The two GPUs differ substantially in raw compute resources. The N1X 48SM carries 6144 shading units, 384 texture mapping units, 48 render output units, 48 ray tracing cores, and 192 tensor cores. The RTX 2000 Mobile Ada Generation has 3072 shading units, 96 texture mapping units, 48 render output units, 24 ray tracing cores, and 96 tensor cores. In every compute category except render output units, the N1X 48SM doubles the RTX 2000 Mobile Ada Generation's count. The shading unit count is exactly double, the texture mapping unit count is exactly quadruple, the ray tracing core count is exactly double, and the tensor core count is exactly double.

The FP32 throughput figures reinforce this scaling. The N1X 48SM reaches 28.83 TFLOPS, while the RTX 2000 Mobile Ada Generation reaches 12.99 TFLOPS. The N1X 48SM delivers approximately 2.2 times the FP32 performance of the RTX 2000 Mobile Ada Generation. The FP16 figures match the FP32 figures for both parts, with both listing 28.83 TFLOPS and 12.99 TFLOPS respectively at a 1:1 ratio. Texture fill rate shows an even larger gap: the N1X 48SM produces 900.9 GTexel/s versus 203.0 GTexel/s for the RTX 2000 Mobile Ada Generation, a ratio of roughly 4.4 to 1. Pixel fill rate is closer, with the N1X 48SM at 112.6 GPixel/s and the RTX 2000 Mobile Ada Generation at 101.5 GPixel/s, about 11% higher for the N1X 48SM.

Memory capacity and bandwidth also show clear separation. The N1X 48SM has 128 GB of LPDDR5X on a 256-bit bus, yielding 273.2 GB/s of bandwidth. The RTX 2000 Mobile Ada Generation has 8 GB of GDDR6 on a 128-bit bus, yielding 256.0 GB/s of bandwidth. The N1X 48SM offers 16 times the memory capacity and about 6.7% more bandwidth. The memory clock figures differ, with the N1X 48SM running at 1067 MHz (8.5 Gbps effective) and the RTX 2000 Mobile Ada Generation at 2000 MHz (16 Gbps effective), but the wider bus on the N1X 48SM compensates for the lower per-pin speed.

Clock speeds tell a different story. The RTX 2000 Mobile Ada Generation has a base clock of 1635 MHz and a boost clock of 2115 MHz. The N1X 48SM has a base clock of 741 MHz and a boost clock of 2346 MHz. The RTX 2000 Mobile Ada Generation runs 894 MHz higher at base, but the N1X 48SM runs 231 MHz higher at boost. This unusual profile suggests the N1X 48SM is designed to ramp aggressively under load rather than maintain high idle frequencies.

Where Each One Wins

Without recorded benchmark scores, win categories must be derived from the specification data. The N1X 48SM wins decisively in raw computational throughput. Its FP32 output of 28.83 TFLOPS is more than double the 12.99 TFLOPS of the RTX 2000 Mobile Ada Generation. Applications that scale with shading units, texture units, or tensor cores will favor the N1X 48SM. The 384 TMUs versus 96 TMUs gives it a massive advantage in texture-heavy workloads, and the 900.9 GTexel/s texture rate reflects that.

The N1X 48SM also wins in memory capacity by an enormous margin. The 128 GB LPDDR5X configuration dwarfs the 8 GB GDDR6 of the RTX 2000 Mobile Ada Generation. For workloads that require large resident datasets, such as machine learning inference with large models or in-memory databases, the N1X 48SM holds a clear advantage. The bandwidth difference is smaller, 273.2 GB/s versus 256.0 GB/s, but the capacity difference is overwhelming.

The RTX 2000 Mobile Ada Generation wins in API support and software compatibility. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This is a critical distinction: the RTX 2000 Mobile Ada Generation is a fully featured consumer and professional graphics solution with modern graphics API support, while the N1X 48SM appears to be a compute-focused or IGP-oriented part without standard graphics API exposure. The RTX 2000 Mobile Ada Generation also has a defined power envelope of 50 W, while the N1X 48SM lists its TDP as unknown.

The RTX 2000 Mobile Ada Generation wins in base clock speed, 1635 MHz versus 741 MHz, which may translate to better sustained performance in power-constrained scenarios if the N1X 48SM cannot maintain its boost clock. The RTX 2000 Mobile Ada Generation also benefits from a higher memory clock, 2000 MHz versus 1067 MHz, though the effective bandwidth is lower due to the narrower bus.

In ray tracing, the N1X 48SM has 48 RT cores versus 24 RT cores on the RTX 2000 Mobile Ada Generation. The N1X 48SM doubles the ray tracing hardware, but the RTX 2000 Mobile Ada Generation has actual graphics API support that would allow ray tracing workloads to run in standard DirectX or Vulkan environments. The N1X 48SM lists no graphics API support, so its ray tracing cores may only be usable through proprietary or compute-oriented interfaces.

Architecture Differences

The two GPUs come from different NVIDIA architectures. The N1X 48SM uses the GB20B chip based on Blackwell 2.0 architecture, classified under the Blackwell IGP (N1x) generation. The RTX 2000 Mobile Ada Generation uses the AD107 chip based on Ada Lovelace architecture, classified under the Ada-MW generation. Both are fabricated on a 5 nm process at TSMC, but the chip characteristics diverge significantly.

The N1X 48SM has a die size of 382 mm² with transistor count listed as unknown. The RTX 2000 Mobile Ada Generation has a die size of 159 mm² with 18,900 million transistors. The transistor density of the RTX 2000 Mobile Ada Generation is 118.9 million transistors per mm². The N1X 48SM's die is roughly 2.4 times larger, which is consistent with its higher core counts and larger memory interface. The N1X 48SM's transistor count is not recorded, so a direct density comparison is not possible.

Memory architecture differs in type and capacity. The N1X 48SM uses 128 GB of LPDDR5X with a 256-bit bus. The RTX 2000 Mobile Ada Generation uses 8 GB of GDDR6 with a 128-bit bus. LPDDR5X is a low-power memory standard typically used in mobile and integrated contexts, while GDDR6 is a dedicated graphics memory standard. The N1X 48SM's memory operates at 1067 MHz with 8.5 Gbps effective data rate, while the RTX 2000 Mobile Ada Generation's memory operates at 2000 MHz with 16 Gbps effective data rate. The N1X 48SM compensates for the lower per-pin data rate with a wider bus, achieving 273.2 GB/s versus 256.0 GB/s.

The bus interface also differs. The N1X 48SM uses PCIe 5.0 x16, while the RTX 2000 Mobile Ada Generation uses PCIe 4.0 x16. The N1X 48SM's PCIe 5.0 interface provides double the per-lane bandwidth of PCIe 4.0, which matters for data transfer between the GPU and host system. Both are listed as IGP slot width with no power connectors, but the RTX 2000 Mobile Ada Generation has a defined 50 W TDP while the N1X 48SM's TDP is unknown.

Display outputs differ: the N1X 48SM has 1x HDMI, while the RTX 2000 Mobile Ada Generation has display outputs described as Portable Device Dependent. The N1X 48SM's release date is 2026-05-31, while the RTX 2000 Mobile Ada Generation was released on 2023-03-20. The RTX 2000 Mobile Ada Generation has a predecessor listed as Ampere-MW and a successor listed as Blackwell-MW. The N1X 48SM has no predecessor or successor listed.

The API support gap is the most significant architectural differentiator. The N1X 48SM lists DirectX, OpenGL, and Vulkan all as N/A. The RTX 2000 Mobile Ada Generation lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means the RTX 2000 Mobile Ada Generation is a standard graphics processor that can run conventional graphics workloads, while the N1X 48SM appears to lack standard graphics API support entirely, suggesting a compute-first or specialized role.

The Verdict

The data shows two very different products that happen to share the NVIDIA brand and a 5 nm TSMC process. The NVIDIA N1X 48SM is a massively provisioned compute device with 6144 shading units, 48 ray tracing cores, 192 tensor cores, and 128 GB of LPDDR5X memory. Its FP32 throughput of 28.83 TFLOPS places it well above the RTX 2000 Mobile Ada Generation's 12.99 TFLOPS. Its 273.2 GB/s memory bandwidth exceeds the RTX 2000 Mobile Ada Generation's 256.0 GB/s, and its 128 GB capacity is 16 times larger.

However, the N1X 48SM lists no DirectX, OpenGL, or Vulkan support. That is not a minor omission. It means the N1X 48SM cannot run standard graphics applications, games, or GPU compute frameworks that rely on those APIs. The RTX 2000 Mobile Ada Generation supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it a conventional and broadly compatible GPU.

For any workload that requires standard graphics rendering, the RTX 2000 Mobile Ada Generation is the only viable choice between the two. Its 50 W TDP also indicates a power-bounded design suitable for mobile integration. For workloads that are compute-focused and can operate without standard graphics APIs, the N1X 48SM offers dramatically higher raw throughput and memory capacity. The data does not record any benchmark scores, so no measured performance verdict is possible, but the specification sheet clearly favors the N1X 48SM for raw compute and the RTX 2000 Mobile Ada Generation for software compatibility and defined power characteristics.

Both parts sit at the 50th percentile versus all GPUs in the database, according to the recorded percentile fields, though neither has an average benchmark score listed. The production status for both is Active. The N1X 48SM is a newer design, with a release date of 2026-05-31, while the RTX 2000 Mobile Ada Generation dates to 2023-03-20.
