NVIDIA N1X 40SM vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

# Head-to-Head Benchmarks

The recorded data for these two NVIDIA mobile graphics solutions presents an interesting comparison, though direct benchmark scores are not available in the database for either part. The NVIDIA N1X 40SM and the NVIDIA RTX 2000 Mobile Ada Generation occupy different positions in the product stack, and their specifications tell a clear story about relative performance expectations.

The N1X 40SM delivers significantly higher raw compute throughput. Its FP32 performance is recorded at 24.02 TFLOPS, which is 84.9% higher than the RTX 2000 Mobile Ada Generation's 12.99 TFLOPS. This advantage stems from the N1X 40SM's larger shader array: 5120 shading units compared to 3072 on the RTX 2000 Mobile. The N1X 40SM also fields 320 texture mapping units versus 96, and 40 RT cores versus 24. These differences translate directly into the texture rate figures: the N1X 40SM achieves 750.7 GTexel/s, while the RTX 2000 Mobile records 203.0 GTexel/s, a 3.7x gap in texture throughput.

The pixel rate comparison is closer. The N1X 40SM produces 93.84 GPixel/s, while the RTX 2000 Mobile reaches 101.5 GPixel/s. The RTX 2000 Mobile actually holds a 8.2% advantage here, driven by its higher base clock (1635 MHz versus 741 MHz) and its 48 ROPs compared to 40. This means that while the N1X 40SM excels at shader-heavy and texture-heavy workloads, the RTX 2000 Mobile can edge ahead in fill-rate-bound scenarios.

Clock speeds reveal another layer. The N1X 40SM has a base clock of 741 MHz and a boost clock of 2346 MHz. The RTX 2000 Mobile starts at 1635 MHz base and boosts to 2115 MHz. The N1X 40SM's boost clock is 231 MHz higher, but its base clock is 894 MHz lower. This wide clock range on the N1X 40SM suggests substantial dynamic behavior, likely dependent on thermal and power headroom within the integrated graphics context.

Memory configurations differ substantially. The N1X 40SM uses 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The RTX 2000 Mobile uses 8 GB of GDDR6 on a 128-bit bus, providing 256.0 GB/s. The N1X 40SM's bandwidth advantage is 6.7%, despite using system-style LPDDR5X memory rather than dedicated GDDR6. The effective memory speed for the N1X 40SM is 8.5 Gbps, while the RTX 2000 Mobile runs at 16 Gbps effective. The N1X 40SM compensates for the lower per-pin speed with double the bus width.

Tensor core counts also favor the N1X 40SM: 160 tensor cores versus 96. FP16 performance mirrors FP32 at 24.02 TFLOPS for the N1X 40SM and 12.99 TFLOPS for the RTX 2000 Mobile, both at 1:1 ratio. This indicates that AI-accelerated workloads, such as DLSS-style frame generation or neural rendering features, would see a substantial throughput advantage on the N1X 40SM, provided software support exists.

The absence of direct benchmark scores in the database means the head-to-head analysis relies entirely on specification-derived performance indicators. The N1X 40SM wins decisively in FP32 compute, texture rate, tensor throughput, and memory capacity. The RTX 2000 Mobile wins in pixel rate and base clock stability. The API support situation is notable: the N1X 40SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A, while the RTX 2000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This discrepancy is critical for real-world software compatibility.

# The Verdict

The data indicates two very different products aimed at different usage profiles. The NVIDIA N1X 40SM, built on the Blackwell 2.0 architecture with the GB20B chip, is an integrated graphics processor (IGP) with no power connectors and no TDP specified. It presents as a high-end IGP solution with enormous memory capacity (128 GB) and compute resources that exceed the discrete-class RTX 2000 Mobile.

The RTX 2000 Mobile Ada Generation, based on the AD107 chip with Ada Lovelace architecture, is a 50 W mobile discrete GPU. It has a defined power envelope, established API support, and a 2023 release date. The N1X 40SM carries a 2026 release date, making it a much newer design.

For users who need established software compatibility, the RTX 2000 Mobile is the only choice between these two. The N1X 40SM's N/A API listings suggest it may not support conventional graphics APIs in the same manner, possibly indicating a specialized compute-focused or embedded role. The RTX 2000 Mobile supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, enabling mainstream gaming and professional applications.

For raw compute throughput, the N1X 40SM holds a commanding lead. Its 24.02 TFLOPS FP32 performance and 5120 shading units place it in a different performance class. The 128 GB memory capacity is extraordinary for any graphics processor, far exceeding the 8 GB on the RTX 2000 Mobile. This makes the N1X 40SM potentially suited for large-scale data processing, AI inference with massive model footprints, or visualization tasks that demand extensive memory residency.

The RTX 2000 Mobile's 50 W TDP provides a concrete power constraint, while the N1X 40SM has no recorded TDP. The N1X 40SM uses no power connectors, consistent with an IGP that draws power through its host system. The RTX 2000 Mobile also uses no power connectors, relying on the mobile platform's power delivery.

The data suggests that a buyer or system integrator selecting between these two would choose based on workload type. The RTX 2000 Mobile serves traditional graphics applications with full API support and a known power profile. The N1X 40SM serves compute-heavy, memory-hungry applications where API compatibility is less relevant or where the host system provides the necessary drivers and runtime environment.

The RTX 2000 Mobile belongs to the Ada Lovelace architecture, in the Ada-MW generation. Both use a 5 nm TSMC process, but the chip designs are entirely different.

The N1X 40SM's GB20B chip is considerably larger at 382 mm², more than double the RTX 2000 Mobile's 159 mm² AD107 die. This size difference reflects the N1X 40SM's much larger compute resource allocation: 5120 shading units, 320 TMUs, 160 tensor cores, and 40 RT cores. The RTX 2000 Mobile allocates 3072 shading units, 96 TMUs, 96 tensor cores, and 24 RT cores.

Memory architecture differs fundamentally. The N1X 40SM integrates LPDDR5X memory, likely system memory shared with the host processor, given its 128 GB capacity and IGP classification. The RTX 2000 Mobile uses dedicated GDDR6 memory with 8 GB capacity. The N1X 40SM's 256-bit bus is twice as wide as the RTX 2000 Mobile's 128-bit bus, allowing it to achieve higher bandwidth despite lower effective memory speed.

Tensor core counts favor the N1X 40SM at 160 versus 96. RT core counts favor the N1X 40SM at 40 versus 24.
