NVIDIA GeForce RTX 4070 vs NVIDIA N1 16SM Comparison

The Verdict

The recorded data draws a decisive line between these two NVIDIA parts. The GeForce RTX 4070 is a finished, measured product with a full benchmark profile, while the NVIDIA N1 16SM is an active, unbenchmarked integrated graphics processor with no recorded scores. For any workload that requires proven graphics performance, the RTX 4070 is the only choice supported by data. The N1 16SM has zero recorded benchmark scores, zero wins in head-to-head comparisons, and an average benchmark score of 0. Its 50th percentile ranking versus all GPUs places it in the middle of the database, but that ranking is not supported by any actual test results.

The RTX 4070 sits at the 81st percentile versus all GPUs, with an average benchmark score of 37,648. Its nearest rivals in the database include the NVIDIA Tesla P4 (average score 37,628, within 0.1 percent), the AMD Radeon RX Vega 56 (average score 37,507, within 0.4 percent), the NVIDIA GeForce RTX 4080 Mobile (average score 38,135, trailing by 1.3 percent), and the AMD Radeon PRO W6400 (average score 37,157, leading by 1.3 percent). These deltas show a tightly clustered performance band, with the RTX 4070 essentially matching its closest competitors.

The N1 16SM, by contrast, offers no comparable evidence. It has no benchmarks, no nearest rivals, and no wins. The data cannot support any performance claim for it. The RTX 4070 is the clear pick for desktop users needing verified graphics throughput. The N1 16SM is an IGP with a large memory pool and a modern architecture, but its performance remains unquantified.

Architecture Differences

The RTX 4070 uses the AD104 chip 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 16SM uses the GB20B chip built on the Blackwell 2.0 architecture, also fabricated by TSMC on a 5 nm process, but its die is larger at 382 mm². Transistor count and density for the N1 16SM are listed as unknown in the database.

The RTX 4070 is a discrete dual-slot card with a 240 mm length, 110 mm height, and 40 mm width. It requires a PCIe 4.0 x16 bus interface, a 200 W TDP, a 550 W suggested PSU, and a single 16-pin power connector. The N1 16SM is an integrated graphics processor with an IGP slot width, no power connectors, and no listed dimensions. It uses a PCIe 5.0 x16 bus interface, and its TDP is unknown.

Memory architecture differs substantially. The RTX 4070 carries 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The N1 16SM carries 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The N1 16SM has more than ten times the memory capacity but less than 55 percent of the bandwidth.

Compute resources diverge sharply. The RTX 4070 has 5,888 shading units, 184 texture mapping units, 64 raster output units, 46 RT cores, and 184 tensor cores. The N1 16SM has 2,048 shading units, 128 TMUs, 24 ROPs, 16 RT cores, and 64 tensor cores. Pixel rates are 158.4 GPixel/s for the RTX 4070 versus 56.30 GPixel/s for the N1 16SM. Texture rates are 455.4 GTexel/s versus 300.3 GTexel/s. FP32 and FP16 performance are both 29.15 TFLOPS for the RTX 4070, versus 9.609 TFLOPS for the N1 16SM.

API support also separates the two. The RTX 4070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A. The RTX 4070 has one HDMI 2.1 and three DisplayPort 1.4a outputs. The N1 16SM has a single HDMI output.

Clock behavior differs. The RTX 4070 has a 1920 MHz base and 2475 MHz boost clock, with memory at 1313 MHz and 21 Gbps effective. The N1 16SM has a 741 MHz base and 2346 MHz boost clock, with memory at 1067 MHz and 8.5 Gbps effective. The N1 16SM boosts close to the RTX 4070 but starts from a much lower base.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The RTX 4070 has ten individual benchmark scores, while the N1 16SM has none. This absence of direct comparison data means the only measurable performance evidence comes from the RTX 4070's own profile.

The RTX 4070's 3DMark Steel Nomad DX12 score is 3,854. Its Geekbench OpenCL score is 154,858, and its Geekbench Vulkan score is 174,152. Passmark scores include 139 for DirectX 10, 244 for DirectX 11, 103 for DirectX 12, 320 for DirectX 9, 1,164 for G2D, 26,927 for G3D, and 14,720 for GPU compute. These ten scores sum to an average of 37,648.

By contrast, the N1 16SM has zero recorded scores in any test. The wins counter shows zero for both sides, confirming no direct benchmark comparison exists. The RTX 4070's percentile ranking of 81 places it well above the N1 16SM's 50th percentile, but the N1 16SM's ranking is not backed by any test data.

In relative terms, the RTX 4070's nearest rivals show a tight performance cluster. The Tesla P4 and RX Vega 56 are within 0.4 percent of its average score, while the RTX 4080 Mobile trails by 1.3 percent and the PRO W6400 leads by 1.3 percent. This indicates the RTX 4070 sits in a well-established performance tier.

Where Each One Wins

The RTX 4070 wins decisively in every measurable category. Its FP32 throughput of 29.15 TFLOPS is over three times the N1 16SM's 9.609 TFLOPS. Its pixel rate of 158.4 GPixel/s beats 56.30 GPixel/s by a wide margin. Its texture rate of 455.4 GTexel/s exceeds 300.3 GTexel/s. Its memory bandwidth of 504.2 GB/s compares favorably to 273.2 GB/s. It has more shading units, more TMUs, more ROPs, more RT cores, and more tensor cores.

The N1 16SM wins on memory capacity with 128 GB versus 12 GB, and it has a wider memory bus at 256 bit versus 192 bit. It also has a newer bus interface at PCIe 5.0 x16 versus PCIe 4.0 x16. Its die is larger at 382 mm² versus 294 mm², and it is in active production while the RTX 4070 is end-of-life.

For gaming and compute workloads with DirectX or Vulkan, the RTX 4070 is the only option with API support and verified benchmark results. The N1 16SM's API support is listed as N/A, and it has no recorded performance data. For applications requiring massive memory capacity, such as large dataset handling, the N1 16SM offers 128 GB, but without benchmark evidence of its throughput.

The RTX 4070 suits desktop users who need proven graphics performance, high bandwidth, and broad API compatibility. The N1 16SM suits systems needing integrated graphics with a large memory pool and a modern PCIe 5.0 interface, but its actual performance cannot be quantified from the database. The data favors the RTX 4070 in every measured dimension.
