NVIDIA GeForce RTX 4070 Ti vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 4070 Ti and the NVIDIA N1X 48SM. The head-to-head benchmark array is empty, and the win counts for both products stand at zero. This absence of paired test data means that any comparative performance assessment must rely on the standalone benchmark results available for the RTX 4070 Ti and the architectural characteristics of the N1X 48SM.

The RTX 4070 Ti delivers a substantial set of measured scores across multiple benchmark suites. In 3DMark Steel Nomad DX12, the card records 5024 points. Geekbench OpenCL returns 176953, while Geekbench Vulkan reaches 213808. Passmark results include 187 for DirectX 10, 288 for DirectX 11, 116 for DirectX 12, 352 for DirectX 9, 1200 for G2D, 31624 for G3D, and 18396 for GPU compute. The average benchmark score across all recorded tests is 44795, placing the RTX 4070 Ti at the 84th percentile among all GPUs in the database.

The N1X 48SM has no recorded benchmark scores. Its average benchmark score is listed as 0, and its percentile versus all GPUs is 50. The nearest rivals array is empty, indicating no comparative data points exist for this part. This makes direct numerical comparison impossible, and the analysis must instead focus on what the architectural data suggests about relative capability.

Looking at the RTX 4070 Ti’s nearest rivals provides context for its performance tier. The NVIDIA GeForce RTX 5090 Mobile scores 45152 on average, which is 0.8% lower than the RTX 4070 Ti’s 44795, meaning the RTX 4070 Ti is actually 0.8% ahead of that mobile flagship. The AMD Radeon Pro 5500 XT averages 45384, putting it 1.3% ahead of the RTX 4070 Ti. The NVIDIA RTX A6000 scores 44075, which is 1.6% behind the RTX 4070 Ti. The Intel Arc A730M averages 45592, placing it 1.7% ahead. These deltas show the RTX 4070 Ti sits in a tight band around these four products, with performance differences under two percent in either direction.

Architecture Differences

The RTX 4070 Ti is built on the AD104 chip using the Ada Lovelace architecture. The N1X 48SM uses the GB20B chip with Blackwell 2.0 architecture. Both are manufactured by TSMC on a 5 nm process, but the similarities end there.

The AD104 die measures 294 mm² and contains 35,800 million transistors, translating to a transistor density of 121.8 million per square millimeter. The GB20B die is larger at 382 mm², though its transistor count is listed as unknown, and density data is absent. The larger die area for the N1X 48SM suggests a physically bigger chip, but without transistor counts, density comparisons cannot be made.

Clock speeds differ significantly. The RTX 4070 Ti runs a base clock of 2310 MHz and boosts to 2610 MHz. The N1X 48SM has a much lower base clock of 741 MHz but a boost clock of 2346 MHz, which is still below the RTX 4070 Ti’s base frequency. Memory clocks also diverge: the RTX 4070 Ti uses 1313 MHz with 21 Gbps effective speed, while the N1X 48SM runs 1067 MHz with 8.5 Gbps effective.

Shader resources show a notable split. The RTX 4070 Ti has 7680 shading units, 240 TMUs, and 80 ROPs. The N1X 48SM has fewer shading units at 6144 but more TMUs at 384, and only 48 ROPs. Ray tracing cores number 60 on the RTX 4070 Ti versus 48 on the N1X 48SM. Tensor cores are 240 versus 192.

Memory configurations are fundamentally different. The RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The N1X 48SM uses 128 GB of LPDDR5X on a 256-bit bus, with 273.2 GB/s of bandwidth. The N1X 48SM has far more capacity but less than half the bandwidth per second. Pixel rates reflect the ROP count: 208.8 GPixel/s for the RTX 4070 Ti versus 112.6 GPixel/s for the N1X 48SM. Texture rates favor the N1X 48SM at 900.9 GTexel/s against 626.4 GTexel/s for the RTX 4070 Ti, driven by its higher TMU count.

Compute throughput: the RTX 4070 Ti reaches 40.09 TFLOPS in both FP32 and FP16, with a 1:1 ratio. The N1X 48SM delivers 28.83 TFLOPS in both, also 1:1. The RTX 4070 Ti holds a clear lead in raw floating-point work.

API support separates the two. The RTX 4070 Ti supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan, indicating it may not expose standard graphics APIs in the same way.

Physical design differs as well. The RTX 4070 Ti is a dual-slot card measuring 285 mm in length, 112 mm in height, and 42 mm in width, requiring a single 16-pin power connector and a 600 W suggested PSU. The N1X 48SM is an IGP (integrated graphics processor) with no slot width, no power connectors, and no dimensions recorded.

Where Each One Wins

The RTX 4070 Ti wins in scenarios demanding high-bandwidth, high-throughput rasterization and ray tracing. Its 504.2 GB/s memory bandwidth, 60 RT cores, and 40.09 TFLOPS FP32 compute make it suited for conventional gaming workloads and DirectX 12 applications. The recorded Passmark DirectX 11 score of 288 and DirectX 12 score of 116, alongside the 3DMark Steel Nomad result of 5024, confirm its strength in these areas. The 84th percentile ranking among all GPUs places it in the upper tier of discrete graphics cards.

The N1X 48SM wins in contexts requiring massive memory capacity and high texture throughput. Its 128 GB of LPDDR5X memory exceeds the RTX 4070 Ti’s 12 GB by a factor of over ten. The 900.9 GTexel/s texture rate is 43.8% higher than the RTX 4070 Ti’s 626.4 GTexel/s. These characteristics point toward workloads involving large datasets, texture-heavy compute, or integrated-system deployments where dedicated power connectors are unavailable.

The N1X 48SM also holds advantages in bus interface generation, using PCIe 5.0 x16 versus the RTX 4070 Ti’s PCIe 4.0 x16. This newer bus standard offers higher potential transfer rates to the host system, though the actual bandwidth difference depends on platform support.

The RTX 4070 Ti is listed as end-of-life production status, while the N1X 48SM is active. The RTX 4070 Ti has a release date of January 2023, with a predecessor in GeForce 30 and a successor in GeForce 50. The N1X 48SM has a release date of May 2026, with no predecessor or successor listed, and belongs to the Blackwell IGP generation.

Power characteristics are only partially known. The RTX 4070 Ti has a TDP of 285 W. The N1X 48SM lists TDP as unknown, which is consistent with its IGP classification where power consumption may be variable or shared with a host processor.

The data indicates two products designed for fundamentally different roles. The RTX 4070 Ti is a discrete, high-performance graphics card with extensive benchmark validation and a clear gaming-oriented feature set. The N1X 48SM is an integrated graphics solution with enormous memory capacity, higher texture throughput, and a newer bus interface, but it lacks any recorded performance measurements and exposes no standard graphics APIs in the database. Without benchmark data for the N1X 48SM, quantitative comparison is limited to architectural specifications, where the RTX 4070 Ti leads in compute throughput, memory bandwidth, pixel rate, and ray tracing resources, while the N1X 48SM leads in memory capacity, texture rate, TMU count, and bus interface generation.
