NVIDIA GeForce RTX 4050 Mobile vs NVIDIA N1 20SM Comparison

NVIDIA GeForce RTX 4050 Mobile is a discrete mobile graphics solution built on the Ada Lovelace architecture, while NVIDIA N1 20SM is an integrated graphics processor based on the newer Blackwell 2.0 architecture. The database records show that the RTX 4050 Mobile has an average benchmark score of 19049, placing it in the 63rd percentile among all GPUs, while the N1 20SM has no recorded benchmarks and sits at the 50th percentile with an average score of 0. This comparison examines the measurable differences between these two NVIDIA offerings.

Head-to-Head Benchmarks

The RTX 4050 Mobile has nine recorded benchmark results in the database, while the N1 20SM has none. This absence of recorded data for the N1 20SM means that direct score comparisons are not possible from the current measurements. However, the RTX 4050 Mobile’s performance can be contextualized through its nearest rivals.

The RTX 4050 Mobile’s average benchmark score of 19049 places it nearly equal to the AMD Radeon RX 6600, which has an average score of 19036, a delta of 0.1% in favor of the RTX 4050 Mobile. The NVIDIA Quadro K6000 scores 19030, again a 0.1% difference favoring the RTX 4050 Mobile. The NVIDIA Tesla K20m records an average of 19089, which is 0.2% ahead of the RTX 4050 Mobile. The NVIDIA RTX 2000 Ada Generation scores 18954, putting it 0.5% behind the RTX 4050 Mobile. These narrow margins indicate that the RTX 4050 Mobile sits in a tightly contested performance band.

In individual benchmark tests, the RTX 4050 Mobile shows its strongest results in Geekbench Vulkan with a score of 75235 and Geekbench OpenCL with 74748. The Passmark G3D score reaches 14423, while Passmark GPU Compute records 5947. Legacy DirectX tests show lower scores: Passmark DirectX 9 at 184, DirectX 11 at 130, DirectX 10 at 79, and DirectX 12 at 61. The 2D graphics score is 633.

Since the N1 20SM has no benchmark entries, the recorded data cannot establish any head-to-head wins for either product. The winsA and winsB fields in the database both show zero. The RTX 4050 Mobile’s performance profile is therefore defined entirely by its own scores and its position relative to its nearest rivals, not by any direct comparison with the N1 20SM.

Architecture Differences

The RTX 4050 Mobile uses the AD107 chip built on the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It contains 18,900 million transistors on a die size of 159 mm², yielding a transistor density of 118.9 million per mm². The N1 20SM uses the GB20B chip with the Blackwell 2.0 architecture, also fabricated on a 5 nm process at TSMC. Its die size is 382 mm², which is substantially larger than the RTX 4050 Mobile’s, but its transistor count is recorded as unknown, and no transistor density figure is available.

Clock speeds differ significantly. The RTX 4050 Mobile has a base clock of 1455 MHz and a boost clock of 1755 MHz. The N1 20SM has a much lower base clock of 741 MHz but a considerably higher boost clock of 2346 MHz. This represents a wider boost range for the N1 20SM.

Both GPUs have 2560 shading units and 20 RT cores, along with 80 tensor cores. The TMU counts differ: the RTX 4050 Mobile has 80 texture mapping units, while the N1 20SM has 160, exactly double. The ROP counts also differ, with the RTX 4050 Mobile featuring 48 render output units versus 24 on the N1 20SM.

Memory configurations are markedly different. The RTX 4050 Mobile uses 6 GB of GDDR6 memory on a 96-bit bus, delivering 192.0 GB/s of bandwidth with an effective speed of 16 Gbps. The N1 20SM uses 128 GB of LPDDR5X memory on a 256-bit bus, delivering 273.2 GB/s of bandwidth with an effective speed of 8.5 Gbps. The N1 20SM’s memory capacity is over 21 times larger, and its bandwidth is approximately 42% higher.

The bus interfaces also differ. The RTX 4050 Mobile connects via PCIe 4.0 x8, while the N1 20SM uses PCIe 5.0 x16, doubling the lane count and using a newer generation of the interconnect standard.

API support shows a major divergence. The RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM records DirectX as N/A, OpenGL as N/A, and Vulkan as N/A, indicating no API support is listed in the database.

Power characteristics are only partially recorded. The RTX 4050 Mobile has a TDP of 50 W, while the N1 20SM’s TDP is listed as unknown. Both have a slot width of IGP and no power connectors, but the N1 20SM’s power draw cannot be quantified from the available data.

The display outputs also differ. The RTX 4050 Mobile lists “Portable Device Dependent” as its display output, while the N1 20SM has a single HDMI output.

The FP32 throughput favors the N1 20SM at 12.01 TFLOPS versus 8.986 TFLOPS for the RTX 4050 Mobile, a difference of approximately 34%. The texture rate follows a similar pattern: the N1 20SM achieves 375.4 GTexel/s versus 140.4 GTexel/s for the RTX 4050 Mobile, roughly 2.7 times higher. However, the pixel rate favors the RTX 4050 Mobile at 84.24 GPixel/s versus 56.30 GPixel/s for the N1 20SM.

The release dates show a generation gap. The RTX 4050 Mobile was released on 2023-01-02, while the N1 20SM’s release date is 2026-05-31. The RTX 4050 Mobile’s predecessor is listed as GeForce 30 Mobile and its successor as GeForce 50 Mobile. The N1 20SM has no predecessor or successor recorded.

The Verdict

The recorded data indicates that the RTX 4050 Mobile is a fully benchmarked product with clear performance metrics, while the N1 20SM lacks any benchmark scores in the database. For users requiring verified performance data, the RTX 4050 Mobile provides measurable results, including an average score of 19049 and a 63rd percentile ranking among all GPUs. Its nearest rivals, the AMD Radeon RX 6600 and NVIDIA Quadro K6000, are within 0.1% of its average score, demonstrating that it sits in a competitive performance tier.

The N1 20SM’s architectural specifications suggest different strengths. Its boost clock of 2346 MHz is substantially higher, its FP32 output of 12.01 TFLOPS exceeds the RTX 4050 Mobile’s 8.986 TFLOPS, and its texture rate of 375.4 GTexel/s is more than double. Its 128 GB memory capacity and 273.2 GB/s bandwidth also represent a higher memory capability. However, without benchmark entries, the database cannot confirm how these specifications translate into real-world performance.

The RTX 4050 Mobile supports a full modern API suite, including DirectX 12 Ultimate and Vulkan 1.4, which is essential for contemporary gaming and compute workloads. The N1 20SM has no API support recorded, which limits its applicability in those contexts according to the available data. The RTX 4050 Mobile also has a lower pixel rate of 84.24 GPixel/s versus 56.30 GPixel/s for the N1 20SM, indicating a different rendering balance.

The N1 20SM uses a larger die at 382 mm² compared to 159 mm², and its PCIe 5.0 x16 interface is two generations ahead of the RTX 4050 Mobile’s PCIe 4.0 x8. Its release date of 2026-05-31 places it later in the product timeline. The RTX 4050 Mobile’s TDP is recorded at 50 W, while the N1 20SM’s power consumption is unknown.

The choice between these two depends on the priority of the user. For those needing validated benchmark results, DirectX 12 Ultimate support, and a compact 6 GB memory footprint, the RTX 4050 Mobile is the only option with recorded performance data. For those prioritizing raw specification advantages such as higher FP32 throughput, larger memory capacity, and a faster interconnect, the N1 20SM presents those advantages on paper, though its actual performance remains unmeasured in the database. The data cannot confirm whether the N1 20SM’s architectural advantages would translate into superior real-world results, as no benchmark scores exist for it.
