NVIDIA GeForce RTX 4070 AD103 vs NVIDIA N1 16SM Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark scores for the NVIDIA GeForce RTX 4070 AD103 and the NVIDIA N1 16SM. Both entries in the database show an average benchmark score of 0, with zero benchmark entries listed and zero wins recorded for either part in the head-to-head comparison. The percentile versus all GPUs is 50 for both, indicating that without measured results, neither device can be positioned above the other in the database's ranking framework.

What can be compared directly from the specification data is the raw compute throughput. The GeForce RTX 4070 AD103 delivers 29.15 TFLOPS of FP32 performance, while the N1 16SM delivers 9.609 TFLOPS. That places the RTX 4070 AD103 at approximately three times the FP32 throughput of the N1 16SM. In FP16, the same 29.15 TFLOPS versus 9.609 TFLOPS ratio applies, as both parts list FP16 at a 1:1 ratio with FP32.

Texture and pixel fill rates follow a similar pattern. The RTX 4070 AD103 reaches 455.4 GTexel/s and 158.4 GPixel/s, compared to 300.3 GTexel/s and 56.30 GPixel/s for the N1 16SM. The RTX 4070 AD103 leads by roughly 1.5 times in texture rate and by nearly three times in pixel rate. These figures reflect the substantial difference in shading unit count: 5888 versus 2048, and ROP count: 64 versus 24.

Memory bandwidth is a different story. The RTX 4070 AD103 uses a 192-bit bus with GDDR6X memory rated at 504.2 GB/s, while the N1 16SM uses a 256-bit bus with LPDDR5X memory rated at 273.2 GB/s. The RTX 4070 AD103 still leads, but by a narrower margin of about 1.8 times. The N1 16SM's wider memory bus partially compensates for its slower memory clock, but not enough to close the bandwidth gap.

Clock speeds show an interesting divergence. The RTX 4070 AD103 has a base clock of 1920 MHz and a boost clock of 2475 MHz. The N1 16SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, which is within 5% of the RTX 4070 AD103's boost figure. This suggests the N1 16SM relies heavily on boost behavior to reach its performance ceiling, whereas the RTX 4070 AD103 maintains a higher floor.

Where Each One Wins

The RTX 4070 AD103 wins in every raw compute category recorded in the database. It holds advantages in FP32 throughput, FP16 throughput, texture rate, pixel rate, shading units, TMUs, ROPs, RT cores, tensor cores, and memory bandwidth. The RTX 4070 AD103 also carries 46 RT cores versus 16 on the N1 16SM, and 184 tensor cores versus 64, making it the stronger choice for ray-traced workloads and tensor-based operations such as DLSS or other AI acceleration tasks.

The N1 16SM wins in memory capacity and bus width. Its 128 GB of LPDDR5X memory dwarfs the 12 GB of GDDR6X on the RTX 4070 AD103. The 256-bit bus is wider than the 192-bit bus on the RTX 4070 AD103, which matters for workloads that need to move large datasets into memory without requiring the same peak bandwidth. The N1 16SM also uses PCIe 5.0 x16, while the RTX 4070 AD103 uses PCIe 4.0 x16, giving the N1 16SM a newer host interface.

The N1 16SM is an integrated graphics processor (IGP), meaning it requires no power connector and fits into a system without a separate expansion slot. The RTX 4070 AD103 is a dual-slot discrete card with a 16-pin power connector and a suggested PSU of 550 W. For systems where discrete graphics is impractical or where massive memory capacity is the priority, the N1 16SM presents a viable alternative despite its lower compute throughput.

The RTX 4070 AD103 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1 16SM lists N/A for all three APIs. That makes the RTX 4070 AD103 the only one of the two suitable for modern gaming or graphics applications that rely on those API standards. The N1 16SM's API support is not recorded, so its compatibility with standard graphics software cannot be established from the database.

Architecture Differences

The GeForce RTX 4070 AD103 is built on the AD103 chip using the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The die measures 379 mm² and contains 45,900 million transistors, yielding a transistor density of 121.1M per mm². The N1 16SM uses the GB20B chip with the Blackwell 2.0 architecture, also on a 5 nm process at TSMC. Its die size is 382 mm², slightly larger than the RTX 4070 AD103, but its transistor count is listed as unknown, so density cannot be calculated.

The RTX 4070 AD103 belongs to the GeForce 40 generation and the GeForce 40-series product family, with a predecessor in GeForce 30 and a successor in GeForce 50. The N1 16SM belongs to the Blackwell IGP (N1x) generation and has no predecessor or successor listed in the database. The production status also differs: the RTX 4070 AD103 is end-of-life, while the N1 16SM is active.

Memory technology separates the two clearly. The RTX 4070 AD103 uses GDDR6X with a 192-bit interface, while the N1 16SM uses LPDDR5X with a 256-bit interface. The memory clock on the RTX 4070 AD103 is 1313 MHz (21 Gbps effective), and on the N1 16SM it is 1067 MHz (8.5 Gbps effective). The RTX 4070 AD103's faster memory clock drives its higher bandwidth despite the narrower bus.

The power profile is another major architectural difference. The RTX 4070 AD103 has a TDP of 200 W and requires a 16-pin power connector. The N1 16SM has an unknown TDP, no power connectors, and is classified as an IGP, meaning it draws power through the motherboard rather than a dedicated GPU power input. The suggested PSU for the RTX 4070 AD103 is 550 W; no suggested PSU is recorded for the N1 16SM.

Display outputs differ as well. The RTX 4070 AD103 offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. The N1 16SM lists only 1x HDMI, with no additional outputs recorded. The RTX 4070 AD103 also has physical dimensions of 240 mm length, 110 mm height, and 40 mm width, while the N1 16SM has no recorded dimensions, consistent with its integrated nature.
