NVIDIA GeForce RTX 5070 Mobile vs NVIDIA N1 16SM Comparison

Where Each One Wins

The recorded data splits these two NVIDIA parts into entirely different roles. The GeForce RTX 5070 Mobile is a dedicated graphics processor with a full benchmark suite, while the N1 16SM is an IGP with no recorded benchmark scores. The RTX 5070 Mobile holds every measured win by default, but the N1 16SM wins on memory capacity, texture rate, and boost clock.

The RTX 5070 Mobile delivers 13.13 TFLOPS of FP32 compute against 9.609 TFLOPS for the N1 16SM, a 36.6% advantage in raw shader throughput. That translates into the 5070 Mobile's 122,238 Geekbench OpenCL score and 116,960 Geekbench Vulkan score. The N1 16SM has no entries in the benchmark database, so its real-world performance cannot be quantified from the available data.

The N1 16SM counters with 128 GB of LPDDR5X memory, a massive capacity advantage over the 5070 Mobile's 8 GB of GDDR7. Its 256-bit bus delivers 273.2 GB/s of bandwidth, which trails the 5070 Mobile's 384.0 GB/s but remains substantial for an integrated part. The N1 16SM also posts a higher boost clock at 2346 MHz versus 1425 MHz, and it reaches 300.3 GTexel/s of texture fill rate, outpacing the 5070 Mobile's 205.2 GTexel/s despite having fewer shaders.

For gaming and compute workloads that rely on dedicated graphics, the RTX 5070 Mobile wins outright. For memory-hungry tasks that fit within an IGP's unified memory pool, the N1 16SM offers a capacity advantage that no discrete mobile GPU in this comparison can match.

Architecture Differences

Both chips use the Blackwell 2.0 architecture and are fabricated on TSMC's 5 nm process. The similarities end there.

The RTX 5070 Mobile uses the GB206 chip with a die size of 181 mm² and 21,900 million transistors, yielding a density of 121.0M per mm². The N1 16SM uses the GB20B chip with a 382 mm² die, more than double the area, though its transistor count is listed as unknown.

The RTX 5070 Mobile packs 4608 shading units, 144 TMUs, and 48 ROPs. It includes 36 RT cores and 144 tensor cores. The N1 16SM is smaller in shader count at 2048 units but keeps 128 TMUs and drops to 24 ROPs. Its RT core count is 16 and tensor core count is 64.

Memory architecture differs fundamentally. The 5070 Mobile uses 8 GB of GDDR7 on a 128-bit bus with 384.0 GB/s bandwidth. The N1 16SM uses 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The N1 16SM's memory clock runs at 1067 MHz with 8.5 Gbps effective, while the 5070 Mobile's memory runs at 1500 MHz with 24 Gbps effective.

Clock behavior also separates them. The 5070 Mobile has a base clock of 907 MHz and a boost of 1425 MHz. The N1 16SM starts lower at 741 MHz but boosts much higher to 2346 MHz.

API support diverges sharply. The 5070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not positioned as a gaming or general compute part in the database.

The power profile differs as well. The 5070 Mobile carries a 50 W TDP and uses no power connectors, while the N1 16SM's TDP is unknown. Both are IGP-class slot widths with PCIe 5.0 x16 interfaces. The 5070 Mobile's display outputs are listed as portable device dependent, while the N1 16SM has a single HDMI output.

Release timing also differs. The 5070 Mobile launched on April 14, 2025, and the N1 16SM on May 31, 2026. The 5070 Mobile's predecessor is the GeForce 40 Mobile series, while the N1 16SM has no listed predecessor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two parts. The wins count stands at zero for both, meaning no shared test results exist for direct comparison.

The RTX 5070 Mobile's standalone scores provide the only quantitative performance data. Its Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 establish its compute capability. Passmark results show 20,355 in G3D, 8,279 in GPU compute, 896 in G2D, 214 in DirectX 9, 192 in DirectX 11, 129 in DirectX 10, and 93 in DirectX 12.

The N1 16SM has an average benchmark score of zero and sits at the 50th percentile against all GPUs. The RTX 5070 Mobile sits at the 75th percentile with an average score of 29,928.

Nearest rival data for the 5070 Mobile places it within a tight cluster. It trails the NVIDIA GeForce RTX 3070 Ti by 0.1% (29,945 average score), beats the NVIDIA GeForce RTX 2080 Ti by 0.5% (29,783), trails the AMD Radeon RX 6800 by 0.6% (30,095), and trails the AMD Radeon RX 6700 by 1.7% (30,433). These deltas indicate the 5070 Mobile performs within 2% of four established desktop-class GPUs from previous generations.

Without benchmark entries for the N1 16SM, no head-to-head numeric comparison is possible. The available data allows only architectural and specification comparisons. The N1 16SM's 128 GB memory pool and 300.3 GTexel/s texture rate are its standout measured attributes, but no compute or graphics scores exist to contextualize them.

The Verdict

The data supports a clear split based on workload type. For gaming, 3D rendering, and general GPU compute, the RTX 5070 Mobile is the only viable choice from these two. It has recorded benchmark scores across OpenCL, Vulkan, and multiple DirectX versions, plus a 75th percentile ranking against all GPUs. Its 13.13 TFLOPS FP32 throughput and 384.0 GB/s bandwidth give it a decisive edge in shader-heavy and bandwidth-sensitive tasks.

For workloads that demand massive memory capacity in a single package, the N1 16SM stands alone. Its 128 GB of LPDDR5X memory is 16 times the capacity of the 5070 Mobile's 8 GB GDDR7. The N1 16SM also offers a higher boost clock and higher texture fill rate, suggesting it may handle certain throughput-oriented tasks well, though the lack of benchmark data prevents confirmation.

The 5070 Mobile's nearest rival comparisons show it competes with desktop GPUs from the previous generation. It sits essentially level with the RTX 3070 Ti and RTX 2080 Ti, and within 1.7% of the RX 6800 and RX 6700. This places it as a capable mobile part that matches desktop-class performance from roughly 2020 to 2022.

The N1 16SM's 50th percentile ranking and zero average benchmark score reflect its status as an unproven quantity in the database. Its architecture and specifications suggest a different purpose, likely integrated into a larger system rather than serving as a discrete graphics solution. The single HDMI output and N/A API support reinforce this interpretation.

Users seeking a mobile GPU for games or creative applications should choose the RTX 5070 Mobile based on its measured performance and API compatibility. Users needing a unified memory pool of 128 GB for data-intensive workloads should consider the N1 16SM, understanding that no benchmark data exists to validate its real-world throughput.

The die size difference is substantial, with the N1 16SM's 382 mm² chip more than doubling the 5070 Mobile's 181 mm². The texture rate advantage for the N1 16SM stems from its higher boost clock compensating for fewer TMUs. The 5070 Mobile maintains advantages in pixel rate, FP32 throughput, memory bandwidth, and every API feature. The N1 16SM leads in memory capacity, boost clock, and texture fill rate.
