NVIDIA GeForce RTX 4070 Mobile vs NVIDIA N1 16SM Comparison

The Verdict

The recorded data presents a clear but incomplete picture. The NVIDIA GeForce RTX 4070 Mobile is a fully measured, active mobile graphics processor with a substantial benchmark footprint. Its average benchmark score of 27435 places it at the 73rd percentile among all GPUs in the database. The NVIDIA N1 16SM, by contrast, has an average benchmark score of 0, no recorded benchmark entries, and sits at the 50th percentile, which reflects its status as a newly released integrated graphics part with no validated performance data yet.

For users selecting between these two, the RTX 4070 Mobile is the only option with measurable compute performance. It delivers 15.62 TFLOPS of FP32 throughput and 15.62 TFLOPS of FP16 throughput, with a 1:1 ratio. The N1 16SM provides 9.609 TFLOPS of FP32 and the same 9.609 TFLOPS of FP16, also at a 1:1 ratio. The RTX 4070 Mobile offers 4608 shading units, 144 texture mapping units, and 48 render output units, while the N1 16SM provides 2048 shading units, 128 TMUs, and 24 ROPs. The RTX 4070 Mobile also leads in ray tracing cores with 36 versus 16, and tensor cores with 144 versus 64.

The database shows the RTX 4070 Mobile is competitive with desktop-class parts. Its nearest rival, the AMD Radeon RX 6700 XT, has an average score of 27425, a 0 percent delta. The NVIDIA GeForce RTX 3090 scores 27565, which is 0.5 percent higher. The NVIDIA RTX PRO 4000 Blackwell scores 27135, 1.1 percent lower. The AMD Radeon Pro Vega 20 scores 27839, 1.5 percent higher. These are narrow margins, indicating the RTX 4070 Mobile performs in the same tier as those desktop GPUs.

The N1 16SM cannot be compared in this fashion because no rival data exists in the database. Its architecture and memory configuration suggest a different use case. It has 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth, which exceeds the RTX 4070 Mobile’s 256.0 GB/s. But without benchmarks, the database cannot confirm how that bandwidth translates into application performance.

Architecture Differences

The RTX 4070 Mobile uses the AD106 chip built on NVIDIA’s Ada Lovelace architecture, produced by TSMC on a 5 nm process. The die size is 188 mm² with 22,900 million transistors, yielding a transistor density of 121.8 million per square millimeter. The N1 16SM uses the GB20B chip on the Blackwell 2.0 architecture, also produced by TSMC on a 5 nm process, but with a significantly larger die size of 382 mm². Transistor count and density for the N1 16SM are listed as unknown in the database.

Clock behavior differs substantially. The RTX 4070 Mobile has a base clock of 1395 MHz and a boost clock of 1695 MHz. The N1 16SM has a much lower base clock of 741 MHz but a far higher boost clock of 2346 MHz. Memory clock on the RTX 4070 Mobile is 2000 MHz with 16 Gbps effective data rate, while the N1 16SM runs at 1067 MHz with 8.5 Gbps effective. The memory type also differs: the RTX 4070 Mobile uses 8 GB of GDDR6 on a 128-bit bus, while the N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus. Bandwidth favors the N1 16SM at 273.2 GB/s versus 256.0 GB/s.

The RTX 4070 Mobile supports PCIe 4.0 x8, while the N1 16SM uses PCIe 5.0 x16. The N1 16SM’s display outputs are listed as 1x HDMI, while the RTX 4070 Mobile’s outputs are portable device dependent. Both are integrated graphics packages with no power connectors and an IGP slot width. The RTX 4070 Mobile has a TDP of 115 W; the N1 16SM’s TDP is unknown.

API support diverges sharply. The RTX 4070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A in the database. This means the N1 16SM cannot run conventional graphics APIs according to the recorded data, which limits its role to specific workloads that do not rely on standard graphics stacks.

The RTX 4070 Mobile was released on 2023-01-02 and is part of the GeForce 40 Mobile generation. Its predecessor is GeForce 30 Mobile and its successor is GeForce 50 Mobile. The N1 16SM was released on 2026-05-31, belongs to the Blackwell IGP (N1x) generation, and has no predecessor or successor listed.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RTX 4070 Mobile and the N1 16SM. The wins counter for both parts is 0. This is expected because the N1 16SM has an empty benchmark array. The RTX 4070 Mobile, however, has nine recorded benchmark scores that can be analyzed independently.

In Geekbench OpenCL, the RTX 4070 Mobile scores 109197. In Geekbench Vulkan, it scores 108367. These are the two highest individual scores in its benchmark set. PassMark results are more granular: DirectX 10 scores 116, DirectX 11 scores 179, DirectX 12 scores 85, DirectX 9 scores 223, G2D scores 763, G3D scores 19587, and GPU compute scores 8399.

The G3D score of 19587 is the primary gaming-oriented metric, and it aligns with the average benchmark score of 27435 when combined with the other tests. The GPU compute score of 8399 indicates strong general-purpose compute performance. The DirectX 12 score of 85 is notably lower than the DirectX 11 score of 179, which may suggest driver or workload-specific behavior, but the database records the numbers without additional context.

For the N1 16SM, there are no scores to interpret. The absence of data means any comparison of raw performance is impossible. The database shows the N1 16SM’s average benchmark score as 0, which is not a performance figure but a placeholder for missing measurements.

The RTX 4070 Mobile’s nearest rival comparisons provide context for its standing. Against the AMD Radeon RX 6700 XT, the delta is 0 percent, meaning they are statistically tied. Against the NVIDIA GeForce RTX 3090, the RTX 4070 Mobile is 0.5 percent slower. Against the NVIDIA RTX PRO 4000 Blackwell, it is 1.1 percent faster. Against the AMD Radeon Pro Vega 20, it is 1.5 percent slower. These deltas are all within two percent, placing the RTX 4070 Mobile in a tight performance cluster.

Where Each One Wins

The NVIDIA GeForce RTX 4070 Mobile wins in every measured compute category. It has more shading units (4608 versus 2048), more ROPs (48 versus 24), more ray tracing cores (36 versus 16), and more tensor cores (144 versus 64). Its FP32 and FP16 throughput are both higher at 15.62 TFLOPS versus 9.609 TFLOPS. Its pixel rate is 81.36 GPixel/s versus 56.30 GPixel/s. Its texture rate is 244.1 GTexel/s versus 300.3 GTexel/s, which is the one raw throughput metric where the N1 16SM is ahead.

The N1 16SM wins on memory capacity and bandwidth. It offers 128 GB of memory, which is 16 times the RTX 4070 Mobile’s 8 GB. Its 256-bit memory bus and LPDDR5X memory provide 273.2 GB/s of bandwidth versus 256.0 GB/s. The N1 16SM also has a higher boost clock at 2346 MHz versus 1695 MHz, and a faster PCIe interface at PCIe 5.0 x16 versus PCIe 4.0 x8. Its texture rate of 300.3 GTexel/s exceeds the RTX 4070 Mobile’s 244.1 GTexel/s, despite having fewer TMUs (128 versus 144), which is a result of the higher boost clock.

For gaming and traditional graphics workloads, the RTX 4070 Mobile is the clear choice. Its DirectX 12 Ultimate support, Vulkan 1.4 support, and OpenGL 4.6 support make it compatible with standard graphics applications. The N1 16SM has no API support listed, which excludes it from those workloads entirely.

For large-memory compute tasks, the N1 16SM may be attractive. Its 128 GB memory capacity is far beyond any discrete mobile GPU in the database, and its bandwidth advantage of 273.2 GB/s over 256.0 GB/s suggests it can move large datasets efficiently. The absence of benchmark data, however, means the database cannot verify its actual compute performance.

The RTX 4070 Mobile sits in a competitive position relative to desktop GPUs. It is tied with the AMD Radeon RX 6700 XT, slightly behind the NVIDIA GeForce RTX 3090 and AMD Radeon Pro Vega 20, and slightly ahead of the NVIDIA RTX PRO 4000 Blackwell. The N1 16SM has no comparable data points. The database records the RTX 4070 Mobile as active with a release date in early 2023, while the N1 16SM is also active with a release date in mid-2026, indicating a newer product that has not yet been benchmarked.

In summary, the RTX 4070 Mobile is the measured performer with a full suite of benchmark scores and API support. The N1 16SM is a high-capacity, high-bandwidth integrated GPU with a newer architecture and larger die, but its performance remains unverified in the database.
