NVIDIA GeForce RTX 4070 AD103 vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark scores for the NVIDIA GeForce RTX 4070 AD103 versus the NVIDIA N1X 40SM. Both entries show zero benchmark results, zero average scores, and zero wins in either direction. The head-to-head benchmark table is empty, and the wins counters for both parts remain at zero. Without measured performance data, any direct comparison of frame rates, compute throughput, or rendering performance cannot be made from the available information.

The absence of scores means the percentile fields are identical: both sit at the 50th percentile against all GPUs, which is a neutral placement reflecting the lack of recorded results rather than actual performance equivalence. The data cannot confirm which part is faster in any specific workload, whether rasterization, ray tracing, or compute. The only quantifiable differences appear in the specification fields, which can be analyzed for theoretical capability, but no empirical benchmark validation exists in the database.

Architecture Differences

The two processors come from completely different architectural lineages. The GeForce RTX 4070 AD103 uses the Ada Lovelace architecture, manufactured on a 5 nm process at TSMC, with a die size of 379 mm² and 45,900 million transistors. The N1X 40SM is built on the Blackwell 2.0 architecture, also on a 5 nm TSMC process, with a die size of 382 mm². Transistor count for the N1X is listed as unknown, and transistor density for the RTX 4070 AD103 is recorded at 121.1 million transistors per square millimeter, while the N1X has no density figure.

The generation labels diverge sharply: the RTX 4070 AD103 belongs to the GeForce 40 generation, while the N1X 40SM is part of the Blackwell IGP (N1x) generation. This distinction matters because the N1X is classified as an integrated graphics processor (IGP), whereas the RTX 4070 AD103 is a discrete add-in card. The slot width reflects this: the RTX 4070 AD103 is dual-slot with a 1x 16-pin power connector, while the N1X is an IGP with no power connectors and a null slot width entry.

Core configuration differs across every unit type. The RTX 4070 AD103 has 5,888 shading units, 184 texture mapping units, 64 render output units, 46 ray tracing cores, and 184 tensor cores. The N1X 40SM counters with 5,120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The N1X has more texture units by a wide margin (320 versus 184), while the RTX 4070 AD103 leads in shading units, ROPs, RT cores, and tensor cores.

Clock speeds show a significant divergence. The RTX 4070 AD103 has a base clock of 1920 MHz and a boost of 2475 MHz. The N1X 40SM runs at a much lower base of 741 MHz but boosts to 2346 MHz, which is only 129 MHz below the RTX 4070 AD103's boost. Memory clocks also differ: the RTX 4070 AD103 uses 1313 MHz (21 Gbps effective), while the N1X runs at 1067 MHz (8.5 Gbps effective). The effective data rate difference is substantial: 21 Gbps versus 8.5 Gbps.

Memory subsystems are configured completely differently. The RTX 4070 AD103 has 12 GB of GDDR6X on a 192-bit bus, yielding 504.2 GB/s of bandwidth. The N1X 40SM has 128 GB of LPDDR5X on a 256-bit bus, but only achieves 273.2 GB/s of bandwidth. The N1X has over ten times the capacity but less than 55% of the bandwidth. The bus interface also differs: PCIe 4.0 x16 for the RTX 4070 AD103, PCIe 5.0 x16 for the N1X.

Where Each One Wins

Based purely on specification data, the RTX 4070 AD103 holds theoretical advantages in several compute metrics. Its FP32 throughput is 29.15 TFLOPS versus 24.02 TFLOPS for the N1X, a lead of roughly 21%. FP16 is identical at 1:1 ratios, so the same 5.13 TFLOPS gap applies. Pixel rate favors the RTX 4070 AD103 at 158.4 GPixel/s versus 93.84 GPixel/s for the N1X, a 69% advantage. The RTX 4070 AD103 also has more ray tracing cores (46 versus 40) and more tensor cores (184 versus 160).

The N1X 40SM wins on texture throughput. Its texture rate reaches 750.7 GTexel/s, compared to 455.4 GTexel/s for the RTX 4070 AD103, a 65% lead. This comes directly from its 320 TMUs versus 184. The N1X also holds the memory capacity advantage at 128 GB versus 12 GB, which is a 10.7x difference. The bus width is wider on the N1X (256-bit versus 192-bit), and its PCIe 5.0 interface doubles the generation of the RTX 4070 AD103's PCIe 4.0.

The N1X consumes no external power connectors and is an IGP, meaning it requires no dedicated power delivery. The RTX 4070 AD103 carries a 200 W TDP and requires a 550 W suggested PSU. The N1X's TDP is unknown, but as an IGP with no connectors, its power envelope is inherently different. The RTX 4070 AD103's display outputs include 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the N1X lists only 1x HDMI.

The Verdict

The data presents two parts designed for entirely different roles. The RTX 4070 AD103 is a discrete, dual-slot graphics card with a 200 W TDP, full API support (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), and a complete set of display outputs. It has higher shading unit counts, more ROPs, more RT cores, more tensor cores, higher FP32 throughput, higher pixel rate, and substantially higher memory bandwidth at 504.2 GB/s. Its launch MSRP was 599 USD, and it is now end-of-life.

The N1X 40SM is an integrated graphics processor with no power connectors, no dedicated PSU requirement, and no exposed API support in the database (all listed as N/A). It offers 128 GB of memory, which is an extreme capacity advantage, along with more TMUs and a higher texture rate. Its 256-bit bus is wider, and it uses PCIe 5.0. It is active and scheduled for release in 2026.

From the recorded specifications, the RTX 4070 AD103 is the superior choice for tasks that depend on compute throughput, pixel fill, ray tracing, and memory bandwidth. The N1X 40SM is the appropriate part for workloads that require massive memory capacity and high texture throughput, particularly in an integrated form factor. Neither part has benchmark scores in the database, so the verdict rests on architectural and specification analysis alone. The RTX 4070 AD103 suits traditional discrete GPU workloads, while the N1X 40SM serves an IGP role with unmatched memory size.
