NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA N1 20SM Comparison

FAQ

Q: What is the average benchmark score of the NVIDIA GeForce RTX 5070 Ti Mobile, and how does it rank against all GPUs?

A: The RTX 5070 Ti Mobile has an average benchmark score of 35,435, placing it in the 80th percentile of all GPUs. It sits close to the NVIDIA Quadro GV100 (35,520, 0.2% higher) and the AMD Radeon Pro Duo (35,860, 1.2% higher), while running ahead of the NVIDIA A2 (34,690, 2.1% higher for the 5070 Ti).

Q: Does the NVIDIA N1 20SM have any recorded benchmark scores?

A: No. The database lists no benchmark entries for the N1 20SM, and its average benchmark score is recorded as zero. It holds a 50th percentile rank, but this is based on its specifications rather than any measured test results.

A: The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s bandwidth.

Q: Which GPU has a higher boost clock?

A: The N1 20SM boosts to 2346 MHz, while the RTX 5070 Ti Mobile boosts to 1447 MHz. The N1 20SM also has a lower base clock at 741 MHz compared to 847 MHz on the 5070 Ti.

Q: What are the TDP specifications for these two GPUs?

A: The RTX 5070 Ti Mobile is rated at 60 W. The N1 20SM has an unknown TDP, and the database does not provide a figure for it.

Q: When were these GPUs released according to the database?

A: The RTX 5070 Ti Mobile was released on 2025-02-28. The N1 20SM has a release date of 2026-05-31.

Architecture Differences

Both GPUs share the same Blackwell 2.0 architecture and are manufactured by TSMC on a 5 nm process. The RTX 5070 Ti Mobile uses the GB205 chip, while the N1 20SM uses the GB20B chip. The die sizes differ substantially: the 5070 Ti Mobile measures 263 mm² with 31,100 million transistors, giving a density of 118.3M per mm². The N1 20SM has a larger die at 382 mm², but its transistor count and density are listed as unknown in the database.

The shading unit counts diverge sharply. The RTX 5070 Ti Mobile carries 5,888 shading units, 184 TMUs, and 80 ROPs. The N1 20SM has 2,560 shading units, 160 TMUs, and only 24 ROPs. Ray tracing cores number 46 on the 5070 Ti versus 20 on the N1 20SM, and tensor cores count 184 versus 80. This gives the 5070 Ti a clear advantage in raw shader throughput and ray tracing capability, while the N1 20SM retains a higher texture fill rate due to its 160 TMUs operating at a much higher boost clock.

Memory architecture presents the largest fundamental difference. The 5070 Ti Mobile pairs 12 GB of GDDR7 with a 192-bit bus and achieves 672.0 GB/s. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus but only reaches 273.2 GB/s. The N1 20SM's memory pool is over ten times larger, but its bandwidth is less than half. The 5070 Ti's pixel rate of 115.8 GPixel/s more than doubles the N1 20SM's 56.30 GPixel/s, while the N1 20SM's texture rate of 375.4 GTexel/s exceeds the 5070 Ti's 266.2 GTexel/s.

API support also separates them. The 5070 Ti Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists DirectX, OpenGL, and Vulkan all as N/A. Both use a PCIe 5.0 x16 interface and are classified as IGP slot width with no power connectors. The 5070 Ti's display outputs are portable device dependent, while the N1 20SM has 1x HDMI.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The RTX 5070 Ti Mobile has nine recorded benchmark scores, while the N1 20SM has none. This makes a direct comparison of measured performance impossible. The recorded data for the 5070 Ti shows a Geekbench OpenCL score of 143,870 and a Geekbench Vulkan score of 139,213. Its Passmark scores range from 102 in DirectX 12 to 259 in DirectX 9, with a G3D score of 24,004 and a GPU compute score of 10,101.

For the N1 20SM, the absence of benchmark results means its performance must be inferred from its specification sheet. Its FP32 output is 12.01 TFLOPS, compared to 17.04 TFLOPS on the 5070 Ti Mobile. FP16 follows the same pattern at 12.01 TFLOPS versus 17.04 TFLOPS. The 5070 Ti holds a 41.9% advantage in FP32 throughput based on these figures.

The N1 20SM does win on boost clock, reaching 2346 MHz versus 1447 MHz on the 5070 Ti. This higher clock partially compensates for its lower shader count in texture operations, resulting in a 41.0% higher texture fill rate. However, the 5070 Ti's ROP count of 80 versus 24 gives it a decisive lead in pixel throughput, and its ray tracing core count of 46 versus 20 indicates stronger RT workloads.

The RTX 5070 Ti Mobile's nearest rivals in the database provide context for its standing. It trails the NVIDIA Quadro GV100 by 0.2% and the AMD Radeon Pro Duo by 1.2%, while leading the NVIDIA A2 by 2.1% and the NVIDIA T1000 by 2.4% in average score. These margins are narrow, placing the 5070 Ti in a tightly contested performance band.

The Verdict

The data indicates two GPUs with fundamentally different design targets. The RTX 5070 Ti Mobile is a discrete mobile GPU with measured benchmark results, a 60 W TDP, and a full suite of graphics APIs. Its 17.04 TFLOPS FP32 performance and 672.0 GB/s memory bandwidth position it as a capable rendering part, and its 80th percentile ranking confirms this standing.

The N1 20SM appears to serve a different role as an integrated graphics processor with a massive 128 GB memory pool. Its lack of benchmark data and N/A API support suggest it is not intended for conventional gaming or compute workloads. Its 12.01 TFLOPS FP32 output is lower by 29.5% relative to the 5070 Ti, and its 273.2 GB/s bandwidth is a significant constraint for memory-intensive tasks.

Users who need measured performance, DirectX 12 Ultimate support, and ray tracing capability should select the RTX 5070 Ti Mobile based on the recorded data. Users who require the 128 GB memory capacity and can operate within the N1 20SM's lower bandwidth and unspecified TDP envelope would choose the N1 20SM, but they must accept the absence of any benchmark validation.

Where Each One Wins

The RTX 5070 Ti Mobile wins in every measured performance category available in the database. Its FP32 throughput of 17.04 TFLOPS exceeds the N1 20SM's 12.01 TFLOPS. Its pixel rate of 115.8 GPixel/s is more than double the N1 20SM's 56.30 GPixel/s. Memory bandwidth of 672.0 GB/s is 2.5 times the N1 20SM's 273.2 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1 20SM lists none of these APIs. Its 46 RT cores and 184 tensor cores provide dedicated hardware for ray tracing and AI workloads. The 60 W TDP is specified, whereas the N1 20SM's power draw is unknown.

The N1 20SM wins in memory capacity with 128 GB versus 12 GB, a difference of over tenfold. Its boost clock of 2346 MHz is substantially higher than the 5070 Ti's 1447 MHz. Its texture rate of 375.4 GTexel/s exceeds the 5070 Ti's 266.2 GTexel/s by 41.0%. Its 256-bit memory bus is wider than the 192-bit bus on the 5070 Ti. Its die is larger at 382 mm² versus 263 mm². It has a single HDMI output, whereas the 5070 Ti's outputs are portable device dependent.

For conventional graphics workloads, the RTX 5070 Ti Mobile is the clear choice based on its benchmark scores, API support, and higher compute throughput. For applications that prioritize enormous memory capacity above all else, the N1 20SM offers a unique configuration with 128 GB of LPDDR5X, but its lack of benchmark data means its real-world performance remains unverified. The database records zero wins for either GPU in direct head-to-head tests because no such tests exist.
