NVIDIA GeForce RTX 4070 Ti vs NVIDIA N1 20SM Comparison

Where Each One Wins

The recorded data draws a sharp contrast between these two NVIDIA parts. The GeForce RTX 4070 Ti is a dedicated add-in board with a full benchmark suite, while the N1 20SM is an integrated graphics processor (IGP) with no recorded benchmark scores. The RTX 4070 Ti delivers 40.09 TFLOPS of FP32 throughput, a 3.3x advantage over the N1 20SM's 12.01 TFLOPS. In every measurable category, the RTX 4070 Ti wins outright: pixel rate (208.8 GPixel/s vs 56.30 GPixel/s), texture rate (626.4 GTexel/s vs 375.4 GTexel/s), and memory bandwidth (504.2 GB/s vs 273.2 GB/s). The N1 20SM counters with a 128 GB memory capacity and a PCIe 5.0 x16 interface, but it has zero entries in the benchmark database to substantiate any performance claim.

The RTX 4070 Ti sits at the 84th percentile among all GPUs, with an average benchmark score of 44,795. Its nearest rivals include the RTX 5090 Mobile at 45,152 (0.8% higher), the AMD Radeon Pro 5500 XT at 45,384 (1.3% higher), the RTX A6000 at 44,075 (1.6% lower), and the Intel Arc A730M at 45,592 (1.7% higher). These deltas show the RTX 4070 Ti clustered tightly with a wide range of competing parts, from mobile flagships to professional workstation cards. The N1 20SM, by contrast, holds a 50th percentile ranking with an average score of zero, meaning it has no validated performance data in the database. The use-case split is therefore stark: the RTX 4070 Ti is for discrete rendering and compute workloads where raw throughput matters, while the N1 20SM exists as an integrated solution for systems requiring unified memory access with a modest graphics footprint.

Architecture Differences

The two chips come from different architectural generations. The RTX 4070 Ti uses the AD104 die built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It packs 35,800 million transistors into a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The N1 20SM uses the GB20B chip based on Blackwell 2.0, also on a 5 nm TSMC process, but its transistor count is listed as unknown while its die size is 382 mm². The larger die with an unknown transistor count means density cannot be calculated, but the physical size difference suggests a different design philosophy: the RTX 4070 Ti is a graphics-first chip, while the N1 20SM likely integrates additional system functions given its IGP classification.

Core configurations diverge substantially. The RTX 4070 Ti has 7,680 shading units, 240 texture mapping units, 80 ROPs, 60 RT cores, and 240 tensor cores. The N1 20SM has 2,560 shading units, 160 TMUs, 24 ROPs, 20 RT cores, and 80 tensor cores. The RTX 4070 Ti delivers more than triple the shading units and triple the RT cores, indicating a much heavier geometry and ray tracing workload capacity. The N1 20SM's 24 ROPs versus 80 on the RTX 4070 Ti directly explains the pixel rate gap (56.30 GPixel/s vs 208.8 GPixel/s). Clock behavior also differs: the RTX 4070 Ti runs a 2310 MHz base and 2610 MHz boost, while the N1 20SM runs a 741 MHz base and 2346 MHz boost. The N1 20SM's low base clock with a high boost suggests aggressive power management typical of integrated parts.

Memory architecture is a major differentiator. The RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus, but bandwidth drops to 273.2 GB/s. The N1 20SM's memory is likely shared with the host CPU, which explains the larger capacity and lower bandwidth. The RTX 4070 Ti's memory clock is 1313 MHz (21 Gbps effective), while the N1 20SM runs at 1067 MHz (8.5 Gbps effective). The API support also separates them: the RTX 4070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists N/A for all three APIs. The N1 20SM uses PCIe 5.0 x16 versus the RTX 4070 Ti's PCIe 4.0 x16, but the N1 20SM has no power connectors and is listed as an IGP, while the RTX 4070 Ti is a dual-slot card requiring a 1x 16-pin connector and a 600 W suggested PSU.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two parts, and the N1 20SM has an empty benchmark array. The wins count is zero for both sides in direct comparison. However, the RTX 4070 Ti's individual benchmark scores provide a reference point. In 3DMark Steel Nomad DX12, it scores 5,024. Geekbench OpenCL yields 176,953, and Geekbench Vulkan yields 213,808. Passmark results include G3D at 31,624, GPU Compute at 18,396, DirectX 11 at 288, DirectX 9 at 352, DirectX 10 at 187, DirectX 12 at 116, and G2D at 1,200. These numbers establish the RTX 4070 Ti as a high-end discrete GPU. The N1 20SM's absence from the benchmark suite means any comparative analysis relies on theoretical specifications rather than measured outcomes.

The nearest rival data for the RTX 4070 Ti offers additional context. The RTX 5090 Mobile averages 45,152, which is 0.8% above the RTX 4070 Ti. The AMD Radeon Pro 5500 XT averages 45,384, 1.3% higher. The RTX A6000 averages 44,075, 1.6% lower. The Intel Arc A730M averages 45,592, 1.7% higher. These margins are tight, all within roughly two percentage points, indicating that the RTX 4070 Ti performs in a crowded mid-to-high tier rather than at the absolute top. The N1 20SM has no rival data, so its relative position cannot be assessed beyond its 50th percentile rank, which is derived from zero actual scores and therefore carries no empirical weight.

The Verdict

The data positions the RTX 4070 Ti as a fully realized discrete GPU with validated performance across multiple benchmark suites. Its 84th percentile rank, 44,795 average score, and tight margins against rivals like the RTX 5090 Mobile and RTX A6000 confirm it operates in a competitive tier. Users requiring DirectX 12 Ultimate support, high FP32 throughput (40.09 TFLOPS), and a dual-slot form factor with a 285 W TDP will find the RTX 4070 Ti aligned with their needs. The launch MSRP of 799 USD was recorded at release, and the part is now end-of-life, meaning availability may taper.

The N1 20SM presents a fundamentally different profile. As an active IGP with no power connectors, no TDP listed, and a 128 GB LPDDR5X memory pool, it targets integrated system designs where CPU and GPU share memory. Its 2,560 shading units and 12.01 TFLOPS of FP32 performance are modest, and its N/A API entries suggest it is not intended for general-purpose DirectX or Vulkan workloads. The 50th percentile rank is unsubstantiated by any benchmark data, so the N1 20SM's real-world position remains undefined. The 382 mm² die with Blackwell 2.0 architecture and PCIe 5.0 x16 interface indicate a modern, system-on-chip orientation rather than a discrete graphics card.

The choice between these two parts depends on the platform. The RTX 4070 Ti delivers measured, high-end graphics performance for gaming and compute in a standard PCIe slot. The N1 20SM offers massive memory capacity in an integrated package with no expansion card footprint, but its graphics capabilities are unverified and its API support is absent. The recorded data supports only one conclusion for discrete rendering workloads: the RTX 4070 Ti outperforms the N1 20SM in every recorded metric, while the N1 20SM's strengths lie in memory capacity and integration, not in benchmark-validated graphics throughput.
