NVIDIA GeForce RTX 4070 vs NVIDIA N1X 40SM Comparison

The Verdict

The recorded data presents a clear separation between these two NVIDIA parts. The GeForce RTX 4070 is a finished, measured product with a substantial benchmark history, while the N1X 40SM is an active, integrated GPU with no recorded benchmark scores and a 50th percentile standing among all GPUs. For any user requiring verified performance data, the RTX 4070 is the only option with concrete evidence. Its average benchmark score of 37,648 places it in the 81st percentile of all GPUs, with nearest rivals including the NVIDIA Tesla P4 (0.1% ahead) and the AMD Radeon RX Vega 56 (0.4% ahead). The N1X 40SM, by contrast, shows an average score of zero and no rival comparisons, meaning it cannot be positioned against any product in the database. The data indicates the RTX 4070 delivers verified, competitive performance across DirectX 12, OpenCL, and Vulkan workloads, whereas the N1X 40SM remains an unmeasured entity. The choice is straightforward: the RTX 4070 for any task requiring validated benchmark results, and the N1X 40SM only for systems where its integrated form factor and specific memory configuration are mandatory, with no performance guarantees from the database.

Architecture Differences

The two GPUs stem from different architectural generations. The RTX 4070 uses the AD104 chip built on Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The N1X 40SM uses the GB20B chip on Blackwell 2.0 architecture, also fabricated by TSMC on a 5 nm process, but with a larger 382 mm² die and an unknown transistor count. The RTX 4070 is a discrete add-in board with a dual-slot cooler and a 16-pin power connector, while the N1X 40SM is an integrated graphics processor (IGP) with no power connectors and no specified slot width beyond "IGP". The memory subsystems differ fundamentally: the RTX 4070 has 12 GB of GDDR6X on a 192-bit bus, while the N1X 40SM has 128 GB of LPDDR5X on a 256-bit bus. The RTX 4070 uses a PCIe 4.0 x16 interface, while the N1X 40SM uses PCIe 5.0 x16. The N1X 40SM lacks any API support in the database (DirectX, OpenGL, and Vulkan all marked N/A), whereas the RTX 4070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM's display output is a single HDMI, while the RTX 4070 offers one HDMI 2.1 and three DisplayPort 1.4a outputs. The N1X 40SM is marked as Active in production status, while the RTX 4070 is End-of-life, with a successor in the GeForce 50 series.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the RTX 4070 and the N1X 40SM. The head-to-head benchmark list is empty, and the win counts are zero for both products. This absence of comparative data means the performance relationship must be inferred from each product's individual recorded scores and architectural specifications.

The RTX 4070's 10 recorded benchmark scores provide a complete performance profile. In 3DMark Steel Nomad DX12, it scores 3,854. Geekbench OpenCL yields 154,858, and Geekbench Vulkan yields 174,152. Passmark scores include DirectX 10 at 139, DirectX 11 at 244, DirectX 12 at 103, DirectX 9 at 320, G2D at 1,164, G3D at 26,927, and GPU Compute at 14,720. These scores place the RTX 4070 at the 81st percentile of all GPUs, with an average score of 37,648. The nearest rivals show the RTX 4070 is effectively tied with the Tesla P4 (0.1% difference) and within 1.3% of the RTX 4080 Mobile, indicating consistent mid-to-high range performance.

The N1X 40SM has no recorded benchmarks, no average score, and no rival comparisons. Its percentile standing of 50th is the only positioning data available, and it comes without any supporting measurements. The architecture suggests certain capabilities: the N1X 40SM has a higher texture rate (750.7 GTexel/s vs 455.4 GTexel/s) and more texture mapping units (320 vs 184), indicating potential strength in texture-heavy workloads. However, the RTX 4070 leads in pixel rate (158.4 GPixel/s vs 93.84 GPixel/s), FP32 compute (29.15 TFLOPS vs 24.02 TFLOPS), and ray tracing cores (46 vs 40). The RTX 4070's higher boost clock (2475 MHz vs 2346 MHz) and much higher memory bandwidth (504.2 GB/s vs 273.2 GB/s) suggest better sustained performance in bandwidth-sensitive tasks, despite the N1X 40SM's larger memory pool. The N1X 40SM's memory bandwidth is 54% of the RTX 4070's, a significant gap for any workload relying on data movement. The RTX 4070's FP32 performance is 21% higher than the N1X 40SM's, based on the recorded 29.15 TFLOPS versus 24.02 TFLOPS. Since the N1X 40SM has no measured scores, the RTX 4070 remains the only GPU with verifiable performance in this comparison.
