NVIDIA GeForce RTX 4070 SUPER vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The recorded data for the NVIDIA GeForce RTX 4070 SUPER contains ten benchmark entries, while the NVIDIA N1 20SM has no benchmark scores listed in the database. This makes a direct head-to-head comparison impossible on a test-by-test basis. The RTX 4070 SUPER delivers a Passmark G3D score of 29995, a Geekbench OpenCL score of 172795, and a Geekbench Vulkan score of 205624. Its 3DMark Steel Nomad DX12 score is 4627. The N1 20SM does not have equivalent entries.

The average benchmark score for the RTX 4070 SUPER is 43223, placing it in the 83rd percentile among all GPUs. The N1 20SM is listed with an average benchmark score of 0 and sits in the 50th percentile. The gap in measured performance is stark, but the N1 20SM is an integrated graphics processor, not a discrete add-in board, so the absence of comparable test data aligns with its different role.

The RTX 4070 SUPER's nearest rivals in the database are all close in average score: the NVIDIA Quadro M6000 24 GB (43262, delta -0.1%), the NVIDIA GeForce RTX 5050 Mobile (43268, delta -0.1%), the NVIDIA Quadro M6000 (43301, delta -0.2%), and the NVIDIA GeForce RTX 4090 Mobile (43667, delta -1%). The RTX 4070 SUPER trails the RTX 4090 Mobile by 1%, which is a narrow margin given the mobile part's higher power envelope in its own category. The Quadro M6000 24 GB is effectively tied with the RTX 4070 SUPER, differing by only 0.1%.

Without any head-to-head benchmark entries between the two items, the only quantitative comparison available is the average score and percentile data. The RTX 4070 SUPER's average of 43223 versus the N1 20SM's 0 indicates that the database contains no measured workloads for the latter. The N1 20SM's 50th percentile is a default placement, not a result from testing.

The Verdict

The data supports a clear split. The RTX 4070 SUPER is a discrete graphics card with a full set of benchmark results, an average score of 43223, and an 83rd percentile ranking. The N1 20SM is an integrated graphics processor with no benchmark scores, an average of 0, and a 50th percentile default. Any user selecting between these two for gaming or compute workloads would choose the RTX 4070 SUPER based on the recorded measurements alone.

However, the N1 20SM has attributes that the RTX 4070 SUPER does not. It carries 128 GB of LPDDR5X memory on a 256-bit bus, uses a PCIe 5.0 x16 interface, and is based on the Blackwell 2.0 architecture with a 382 mm² die. The RTX 4070 SUPER uses 12 GB of GDDR6X on a 192-bit bus, a PCIe 4.0 x16 interface, and the Ada Lovelace architecture with a 294 mm² die. The N1 20SM is actively in production, while the RTX 4070 SUPER is end-of-life.

The verdict from the data is that the RTX 4070 SUPER is the only one of the two with any measured performance record. The N1 20SM's role appears to be an integrated processor for systems where a discrete GPU is not needed, but its lack of benchmarks means no performance claims can be made from the database.

Architecture Differences

The two processors come from different NVIDIA architectures. The RTX 4070 SUPER uses Ada Lovelace with the AD104 chip, manufactured on a 5 nm process at TSMC. The N1 20SM uses Blackwell 2.0 with the GB20B chip, also on a 5 nm process at TSMC. Both share the same process node and foundry, but the architectural generation differs.

The RTX 4070 SUPER has 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8 million per mm². The N1 20SM has a larger die at 382 mm², but its transistor count is listed as unknown, and its density is not recorded. The larger die suggests a different integration strategy, consistent with an IGP that includes memory controllers and possibly other system functions.

Shader resources differ significantly. The RTX 4070 SUPER has 7168 shading units, 224 texture mapping units, and 80 raster output units. The N1 20SM has 2560 shading units, 160 TMUs, and 24 ROPs. The RTX 4070 SUPER also has 56 ray tracing cores and 224 tensor cores, while the N1 20SM has 20 RT cores and 80 tensor cores. The RTX 4070 SUPER's higher counts align with its discrete, high-performance positioning.

The N1 20SM's Blackwell 2.0 architecture is newer in naming, but the database does not provide architectural feature details beyond the core counts and process node. The RTX 4070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists DirectX, OpenGL, and Vulkan as N/A, indicating no recorded API support in the database.

Specification Differences

The two items differ across nearly every recorded specification field. The RTX 4070 SUPER has a base clock of 1980 MHz and a boost of 2475 MHz. The N1 20SM has a base clock of 741 MHz and a boost of 2346 MHz. The memory clock also differs: the RTX 4070 SUPER runs at 1313 MHz with 21 Gbps effective, while the N1 20SM runs at 1067 MHz with 8.5 Gbps effective.

Memory capacity and type are major differentiators. The RTX 4070 SUPER has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s bandwidth. The N1 20SM has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The N1 20SM has more than ten times the memory capacity, but the RTX 4070 SUPER has nearly double the bandwidth.

Compute rates follow the core counts. The RTX 4070 SUPER delivers 35.48 TFLOPS FP32 and the same for FP16 (1:1). The N1 20SM delivers 12.01 TFLOPS FP32 and 12.01 TFLOPS FP16 (1:1). Pixel rate is 198.0 GPixel/s for the RTX 4070 SUPER versus 56.30 GPixel/s for the N1 20SM. Texture rate is 554.4 GTexel/s versus 375.4 GTexel/s.

Power and physical specifications also diverge. The RTX 4070 SUPER has a TDP of 220 W, is dual-slot, uses a 1x 16-pin power connector, and has a suggested PSU of 550 W. The N1 20SM has an unknown TDP, is an IGP, has no power connectors, and has no suggested PSU. The RTX 4070 SUPER measures 267 mm in length, 112 mm in height, and 42 mm in width. The N1 20SM has no recorded dimensions.

The RTX 4070 SUPER uses a PCIe 4.0 x16 interface, while the N1 20SM uses PCIe 5.0 x16. Display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a for the RTX 4070 SUPER, versus a single HDMI for the N1 20SM. The RTX 4070 SUPER was released on 2024-01-16 and is end-of-life, with a launch MSRP of 599 USD. The N1 20SM was released on 2026-05-31 and is active, with no launch MSRP.

Where Each One Wins

The RTX 4070 SUPER wins on every measured performance metric recorded in the database. Its average benchmark score of 43223 versus 0 for the N1 20SM is the primary differentiator. It also leads in FP32 compute (35.48 versus 12.01 TFLOPS), pixel rate (198.0 versus 56.30 GPixel/s), texture rate (554.4 versus 375.4 GTexel/s), and memory bandwidth (504.2 versus 273.2 GB/s). It has more shading units, TMUs, ROPs, RT cores, and tensor cores. For any workload that relies on these recorded specifications, the RTX 4070 SUPER is the stronger choice.

The N1 20SM wins in memory capacity, with 128 GB versus 12 GB, and in bus interface generation, using PCIe 5.0 x16 versus PCIe 4.0 x16. It also has a larger die at 382 mm² and a newer release date of 2026-05-31. Its production status is active, while the RTX 4070 SUPER is end-of-life. The N1 20SM's integrated nature means it requires no power connectors and has no slot width, which suits compact system designs.

The data indicates a functional split. The RTX 4070 SUPER is for discrete graphics workloads where raw compute, rendering, and bandwidth matter. The N1 20SM is for integrated scenarios where memory capacity and a modern PCIe link are priorities, but its performance is unmeasured in the database. The RTX 4070 SUPER's 83rd percentile placement among all GPUs reinforces its standing, while the N1 20SM's 50th percentile is a placeholder without test data.
