NVIDIA GeForce RTX 4060 Mobile vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the NVIDIA GeForce RTX 4060 Mobile has a full suite of benchmark results, while the NVIDIA N1X 48SM has no recorded benchmark scores in the database. Consequently, the head-to-head analysis is one-sided by necessity. The RTX 4060 Mobile's average benchmark score is 22,729, placing it at the 67th percentile of all GPUs tracked. The N1X 48SM, by contrast, holds a 50th percentile ranking but with an average benchmark score of 0, indicating no completed tests have been logged.

For the RTX 4060 Mobile, the strongest results appear in DirectX 9 and DirectX 11 legacy workloads, where it scores 216 and 157, respectively, on the PassMark suite. Its DirectX 12 score drops to 73, while DirectX 10 sits at 107. The compute-oriented PassMark GPU compute test yields 6,816, and the general-purpose 3D test (PassMark G3D) returns 17,469. The 2D test shows 730. In cross-platform APIs, the Geekbench OpenCL result is 89,420, and the Vulkan result is 89,569, a near parity that indicates consistent performance across these two compute interfaces.

The nearest rivals in the database provide context for the RTX 4060 Mobile's standing. The NVIDIA GeForce RTX 2080 averages 22,895, which is 0.7% higher than the 4060 Mobile, a negligible margin. The AMD Radeon RX 7700 XT averages 22,549, 0.8% lower. The Intel Arc B580 averages 23,021, 1.3% higher, and the NVIDIA GeForce RTX 5060 Mobile averages 22,435, 1.3% lower. These deltas, all under 1.5%, indicate that the RTX 4060 Mobile sits in a tightly clustered performance band, with no single rival holding a decisive edge in aggregate scoring.

Because the N1X 48SM has no benchmark entries, there are no direct win/loss counts to tabulate. The database records winsA as 0 and winsB as 0, reflecting the absence of head-to-head test data. The analysis must therefore rely on architectural and specification comparisons, where the two parts diverge substantially, to characterize expected behavior.

Where Each One Wins

The RTX 4060 Mobile is a proven quantity in the database. Its benchmark scores cover a range of workloads, from legacy DirectX 9 titles to modern Vulkan compute. The 67th percentile ranking means it outperforms roughly two-thirds of all GPUs in the database. In practical terms, the data indicates it is a capable mobile graphics solution for gaming and general GPU compute, with its DirectX 11 score of 157 and DirectX 9 score of 216 suggesting strong performance in older titles that rely on those APIs. The near-identical Geekbench OpenCL and Vulkan scores, 89,420 and 89,569, show balanced compute performance across vendor-agnostic interfaces.

The N1X 48SM cannot be assigned wins in any benchmark category because no scores exist. However, its specification sheet points to areas where it would likely dominate if tested. The shading unit count is 6,144, exactly double the RTX 4060 Mobile's 3,072. Texture mapping units number 384 versus 96, a 4:1 ratio. The FP32 throughput is 28.83 TFLOPS compared to 11.61 TFLOPS, meaning the N1X 48SM has roughly 2.5 times the raw floating-point capability. Ray tracing cores are 48 versus 24, and tensor cores are 192 versus 96. These figures suggest the N1X 48SM would win heavily in compute-bound and ray-traced workloads, should benchmark data become available.

Memory capacity is another clear differentiator. The N1X 48SM carries 128 GB of LPDDR5X, while the RTX 4060 Mobile has 8 GB of GDDR6. The bus width is 256 bit versus 128 bit, and bandwidth is 273.2 GB/s versus 256.0 GB/s. For workloads that exceed 8 GB of video memory, such as large language model inference or high-resolution texture sets, the N1X 48SM is structurally advantaged. The RTX 4060 Mobile wins in the practical sense of having verified performance data, but the architectural gap in raw resources strongly favors the N1X 48SM for future benchmark entries.

Architecture Differences

The two GPUs come from different architectural generations. The RTX 4060 Mobile uses the AD107 chip based on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC with 18,900 million transistors on a 159 mm² die. The N1X 48SM uses the GB20B chip based on Blackwell 2.0 architecture, also on a 5 nm TSMC process, but with a die size of 382 mm². Transistor count for the N1X 48SM is listed as unknown, and transistor density is not recorded.

The RTX 4060 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists DirectX as N/A, OpenGL as N/A, and Vulkan as N/A. This means the N1X 48SM's API support is either unrecorded or intentionally absent, a significant divergence for a GPU that may target non-graphics compute roles. The RTX 4060 Mobile also has a PCIe 4.0 x8 interface, while the N1X 48SM uses PCIe 5.0 x16, offering double the lane count and a newer generation for host data transfer.

Clock behavior differs sharply. The RTX 4060 Mobile has a base clock of 1545 MHz and a boost clock of 1890 MHz. The N1X 48SM has a much lower base clock of 741 MHz but a higher boost clock of 2346 MHz. This large boost delta (456 MHz higher than the RTX 4060 Mobile) indicates the N1X 48SM relies on aggressive power management and burst behavior. Memory clocks also differ: the RTX 4060 Mobile runs at 2000 MHz with 16 Gbps effective, while the N1X 48SM runs at 1067 MHz with 8.5 Gbps effective. The N1X 48SM compensates with a 256 bit bus versus 128 bit.

The N1X 48SM is classified as an IGP (integrated graphics processor) with no power connectors, and the RTX 4060 Mobile is also listed as IGP with no power connectors. Both are mobile or embedded parts. The RTX 4060 Mobile has a TDP of 115 W, while the N1X 48SM's TDP is unknown. Display outputs for the RTX 4060 Mobile are "Portable Device Dependent," whereas the N1X 48SM lists one HDMI output. The N1X 48SM has 48 ROPs, matching the RTX 4060 Mobile's 48 ROPs, but the pixel rate is higher at 112.6 GPixel/s versus 90.72 GPixel/s due to the higher boost clock.
