NVIDIA N1 16SM vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the NVIDIA N1 16SM or the NVIDIA RTX 3000 Mobile Ada Generation. Both entries show an average benchmark score of 0, and the head-to-head benchmark array is empty. This means no direct performance comparison can be drawn from measured results. The wins count is 0 for both parts, indicating the lack of test data rather than a competitive tie.

The absence of scores does not mean the two GPUs are equal in capability. The raw specifications reveal a substantial difference in compute resources. The RTX 3000 Mobile Ada Generation carries 4608 shading units, 144 texture mapping units, 48 raster operation units, 36 ray tracing cores, and 144 tensor cores. The N1 16SM, by contrast, provides 2048 shading units, 128 TMUs, 24 ROPs, 16 ray tracing cores, and 64 tensor cores. In raw shading throughput, the RTX 3000 Mobile delivers 15.62 TFLOPS FP32, while the N1 16SM reaches 9.609 TFLOPS FP32. That is a 62.5% advantage for the RTX 3000 Mobile in pure FP32 compute, derived directly from the recorded figures.

Texture rate tells a different story. The N1 16SM achieves 300.3 GTexel/s, while the RTX 3000 Mobile Ada reaches 244.1 GTexel/s. The N1 16SM leads by 23.0% in texture fill rate despite having fewer TMUs (128 versus 144). This occurs because the N1 16SM operates at a much higher boost clock of 2346 MHz, compared to 1695 MHz on the RTX 3000 Mobile. The N1 16SM's base clock is lower at 741 MHz versus 1395 MHz, but its boost behavior more than compensates in texture-bound workloads.

Pixel rate favors the RTX 3000 Mobile Ada. It records 81.36 GPixel/s against 56.30 GPixel/s for the N1 16SM, a 44.5% lead. This aligns with the ROP count difference: 48 ROPs on the RTX 3000 Mobile versus 24 on the N1 16SM. Memory bandwidth is close, with the N1 16SM at 273.2 GB/s and the RTX 3000 Mobile at 256.0 GB/s, a modest 6.7% edge for the N1 16SM.

The N1 16SM's memory subsystem is unusual. It pairs 128 GB of LPDDR5X on a 256-bit bus, whereas the RTX 3000 Mobile uses 8 GB of GDDR6 on a 128-bit bus. The N1 16SM's effective memory clock is 8.5 Gbps, while the RTX 3000 Mobile runs at 16 Gbps effective. The wider bus on the N1 16SM offsets the slower per-pin rate, resulting in slightly higher aggregate bandwidth.

Clock behavior is another key separator. The N1 16SM boosts from 741 MHz to 2346 MHz, a 3.17x multiplier from base to boost. The RTX 3000 Mobile goes from 1395 MHz to 1695 MHz, only a 1.22x multiplier. The N1 16SM's aggressive boost curve suggests it is designed for bursty, latency-sensitive workloads that can take advantage of short-duration high-frequency operation. The RTX 3000 Mobile's flatter clock profile points toward sustained, thermally constrained mobile workloads.

The RTX 3000 Mobile Ada supports a full API stack: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists N/A for DirectX, OpenGL, and Vulkan. This is a fundamental difference. The N1 16SM is not exposed as a conventional graphics API device in the recorded data, which strongly suggests its role is compute-accelerator or IGP-specific rather than a general-purpose gaming or workstation GPU.

Where Each One Wins

The N1 16SM wins in texture-bound operations and memory capacity. Its 300.3 GTexel/s texture rate exceeds the RTX 3000 Mobile's 244.1 GTexel/s by 23.0%, making it the stronger part for workloads that repeatedly sample textures or perform similar bilinear/trilinear filter operations. The 128 GB memory pool dwarfs the RTX 3000 Mobile's 8 GB, providing a 16x capacity advantage. Any workload that requires large in-memory datasets, such as certain inference or data-processing tasks, will benefit from the N1 16SM's memory footprint. Its bandwidth of 273.2 GB/s is also 6.7% higher, so large sequential transfers proceed faster.

The RTX 3000 Mobile Ada wins in raw compute throughput, pixel processing, and API compatibility. Its 15.62 TFLOPS FP32 is 62.5% higher than the N1 16SM's 9.609 TFLOPS, which translates directly to faster general-purpose shader work, simulation, and rendering where FP32 math dominates. The 81.36 GPixel/s pixel rate is 44.5% above the N1 16SM's 56.30 GPixel/s, making the RTX 3000 Mobile better suited for rasterization-heavy scenes with many overdraws or high-resolution framebuffer fills. The RTX 3000 Mobile also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so it can run the full breadth of modern graphics applications, while the N1 16SM lists no graphics API support.

The RTX 3000 Mobile's ray tracing and tensor resources are also more numerous: 36 RT cores versus 16, and 144 tensor cores versus 64. The recorded data does not include RT or tensor benchmark scores, so the performance advantage cannot be quantified, but the resource count alone indicates a 2.25x and 2.25x difference, respectively. For workloads that rely on dedicated ray intersection hardware or tensor-core-accelerated matrix math, the RTX 3000 Mobile has more parallel units available.

Thermal design power differs as well. The RTX 3000 Mobile is rated at 115 W, while the N1 16SM has an unknown TDP. The N1 16SM's unknown power draw makes direct efficiency comparisons impossible from the database, but the RTX 3000 Mobile's 115 W figure places it in the mid-range mobile discrete GPU class. The N1 16SM, being an IGP with no power connectors and a PCIe 5.0 x16 bus interface, likely fits a different power envelope, but no recorded number confirms this.

The N1 16SM uses a PCIe 5.0 x16 interface, while the RTX 3000 Mobile uses PCIe 4.0 x16. This gives the N1 16SM a generational advantage in host interface bandwidth, which can matter for data transfers between the CPU and GPU in compute workloads. The RTX 3000 Mobile's display outputs are listed as "Portable Device Dependent," while the N1 16SM provides a single HDMI output. The N1 16SM's fixed HDMI output suggests a specific display configuration, whereas the RTX 3000 Mobile's output flexibility depends on the laptop design.

Specification Differences

The two GPUs differ across nearly every recorded specification category. The N1 16SM uses the GB20B chip under the Blackwell 2.0 architecture, while the RTX 3000 Mobile Ada uses the AD106 chip under Ada Lovelace. The N1 16SM belongs to the Blackwell IGP (N1x) generation, and the RTX 3000 Mobile belongs to the Ada-MW generation. Both are manufactured on a 5 nm process at TSMC, so process node is identical. The RTX 3000 Mobile has a known transistor count of 22,900 million and a die size of 188 mm², resulting in a transistor density of 121.8M per mm². The N1 16SM has an unknown transistor count, a die size of 382 mm², and an unknown transistor density.

Clock speeds differ substantially. The N1 16SM runs at a 741 MHz base and 2346 MHz boost, with memory at 1067 MHz (8.5 Gbps effective). The RTX 3000 Mobile runs at a 1395 MHz base and 1695 MHz boost, with memory at 2000 MHz (16 Gbps effective). The N1 16SM has a much higher boost clock, while the RTX 3000 Mobile has a much higher base clock and faster per-pin memory speed.

Memory configuration diverges completely. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The RTX 3000 Mobile uses 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth. The N1 16SM has 2048 shading units, 128 TMUs, 24 ROPs, 16 RT cores, and 64 tensor cores. The RTX 3000 Mobile has 4608 shading units, 144 TMUs, 48 ROPs, 36 RT cores, and 144 tensor cores. Every compute unit count is higher on the RTX 3000 Mobile except for texture rate, where the N1 16SM's higher clock compensates.

Pixel rate and texture rate differ as noted: 56.30 GPixel/s and 300.3 GTexel/s for the N1 16SM, versus 81.36 GPixel/s and 244.1 GTexel/s for the RTX 3000 Mobile. FP32 and FP16 throughput are both 9.609 TFLOPS for the N1 16SM and 15.62 TFLOPS for the RTX 3000 Mobile, with both parts running FP16 at a 1:1 ratio with FP32. TDP is unknown for the N1 16SM and 115 W for the RTX 3000 Mobile. Both use an IGP slot width and have no power connectors. The N1 16SM uses PCIe 5.0 x16, while the RTX 3000 Mobile uses PCIe 4.0 x16. Display outputs are a single HDMI for the N1 16SM and Portable Device Dependent for the RTX 3000 Mobile.

The RTX 3000 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists N/A for all three APIs. The release dates differ: the N1 16SM entered production status on 2026-05-31, while the RTX 3000 Mobile was released on 2023-03-20. The RTX 3000 Mobile has a predecessor (Ampere-MW) and a successor (Blackwell-MW), while the N1 16SM lists no predecessor or successor.

Architecture Differences

The N1 16SM is built on the Blackwell 2.0 architecture, the second-generation Blackwell design for integrated graphics. The RTX 3000 Mobile Ada Generation is built on Ada Lovelace, a distinctly different architecture family. The N1 16SM's chip is GB20B, a large 382 mm² die with an unknown transistor count. The RTX 3000 Mobile uses AD106, a 188 mm² die with 22,900 million transistors and a density of 121.8M per mm². The N1 16SM's die is roughly twice the physical size, but its transistor count is not recorded, so density comparisons are not possible.

The N1 16SM's memory architecture uses LPDDR5X in a 128 GB configuration on a 256-bit bus. This is a unified memory arrangement typical of integrated GPUs, where the GPU shares the same memory pool as the host system. The RTX 3000 Mobile uses dedicated GDDR6 on a 128-bit bus with 8 GB capacity, a conventional discrete mobile GPU memory setup. The N1 16SM's 256-bit bus width is double that of the RTX 3000 Mobile, which is why its bandwidth remains competitive despite a lower effective memory clock.

The API support gap is the most significant architectural difference. The N1 16SM has no DirectX, OpenGL, or Vulkan support listed. This indicates the Blackwell IGP is not designed as a general-purpose graphics renderer in the traditional sense. The RTX 3000 Mobile, by contrast, supports the full modern graphics stack, including DirectX 12 Ultimate with feature level 12_2, OpenGL 4.6, and Vulkan 1.4. The N1 16SM's role appears to be compute-oriented, possibly for AI inference or specialized rendering tasks that do not rely on conventional graphics APIs.

Ray tracing and tensor core counts differ by the same factor. The RTX 3000 Mobile has 36 RT cores and 144 tensor cores, while the N1 16SM has 16 RT cores and 64 tensor cores. Both architectures include dedicated ray tracing and tensor hardware, but the RTX 3000 Mobile provides more of each. The N1 16SM's lower RT and tensor core counts, combined with its unknown TDP and IGP form factor, suggest a design optimized for a different workload profile than the RTX 3000 Mobile's discrete mobile GPU.

The N1 16SM's PCIe 5.0 x16 interface is a generation ahead of the RTX 3000 Mobile's PCIe 4.0 x16. This matters for host-device data movement. The N1 16SM's display output is a single HDMI, while the RTX 3000 Mobile's display outputs depend on the portable device it is installed in. The N1 16SM's fixed HDMI output aligns with its IGP classification, while the RTX 3000 Mobile's flexible output configuration reflects its mobile discrete GPU design.

The release timeline places the N1 16SM in 2026, three years after the RTX 3000 Mobile's 2023 launch. The N1 16SM's Blackwell 2.0 architecture is the newer design, but the recorded data shows no benchmark scores to indicate whether the architectural generation advantage translates into measured performance gains. The RTX 3000 Mobile's Ada Lovelace architecture has a known predecessor (Ampere-MW) and successor (Blackwell-MW), situating it in a clear product lineage. The N1 16SM stands alone in the database with no predecessor or successor listed.
