NVIDIA GeForce RTX 4050 Mobile vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison. The NVIDIA GeForce RTX 4050 Mobile has nine benchmark scores across DirectX, OpenCL, and Vulkan tests, while the NVIDIA N1X 40SM has no recorded benchmark results in the database. The N1X 40SM carries an average benchmark score of zero, meaning no performance measurements exist for this part. The RTX 4050 Mobile, by contrast, has an average benchmark score of 19,049 across all tests.

The RTX 4050 Mobile posts its strongest results in synthetic compute workloads. In Geekbench OpenCL, it scores 74,748, and in Geekbench Vulkan it reaches 75,235. These are the two highest individual scores recorded for either part in the database, as the N1X 40SM has no corresponding measurements. Passmark G3D shows 14,423, which places the RTX 4050 Mobile solidly above the median GPU in the database at the 63rd percentile of all GPUs tracked. The Passmark GPU compute score of 5,947 further confirms the silicon's compute throughput.

The RTX 4050 Mobile also shows strength in legacy DirectX 9 workloads, scoring 184 in Passmark DirectX 9. Its DirectX 11 score of 130 is likewise above its DirectX 10 result of 79 and DirectX 12 score of 61. The Passmark G2D score of 633 indicates the part handles 2D operations well, though this is less relevant for gaming-oriented analysis.

When placed against nearest rivals in the database, the RTX 4050 Mobile sits within a tight cluster. The AMD Radeon RX 6600 averages 19,036, which is 0.1% below the RTX 4050 Mobile's average. The NVIDIA Quadro K6000 averages 19,030, also 0.1% below. The NVIDIA RTX 2000 Ada Generation averages 18,954, which is 0.5% below. The only rival that scores higher is the NVIDIA Tesla K20m at 19,089, which is 0.2% above the RTX 4050 Mobile. This clustering indicates the RTX 4050 Mobile delivers performance consistent with its class, neither leading nor trailing its immediate competitors by a meaningful margin.

Because the N1X 40SM has zero recorded benchmarks, no head-to-head wins can be assigned to either part. The wins counter shows zero for both. The database does not provide any comparative performance delta between these two specific GPUs. The N1X 40SM's 50th percentile ranking is a placeholder value, not derived from actual measurements, as its average benchmark score is zero. The RTX 4050 Mobile's 63rd percentile ranking, however, derives from real recorded scores across nine separate tests.

The Verdict

The data supports a clear differentiation, though it is not a competitive comparison in the traditional sense. The RTX 4050 Mobile is a fully measured product with nine benchmark scores, a 63rd percentile ranking, and an average score of 19,049 that places it within 0.5% of four established rivals. Any user selecting this part can rely on recorded performance data that shows it on par with the AMD Radeon RX 6600, NVIDIA Quadro K6000, NVIDIA RTX 2000 Ada Generation, and slightly behind the NVIDIA Tesla K20m.

The N1X 40SM, by contrast, presents a specification sheet with no validated performance. Its average benchmark score of zero means the database contains no evidence of actual output. The 50th percentile rank is unsubstantiated. For a buyer or system integrator requiring measured performance, the RTX 4050 Mobile is the only one of these two parts with data to support a decision.

The RTX 4050 Mobile also carries a production status of Active with a release date in early 2023, while the N1X 40SM lists a 2026 release date and no predecessor or successor in its lineage. The RTX 4050 Mobile belongs to the established GeForce 40 Mobile generation, whereas the N1X 40SM is from the Blackwell IGP (N1x) generation. The RTX 4050 Mobile supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the N1X 40SM lists N/A for all three APIs, making it unsuitable for standard gaming or graphics application workloads.

For gaming laptops, the RTX 4050 Mobile's API support and measured scores make it the functional choice. For any workload requiring verified compute results, the N1X 40SM cannot be recommended based on the database, as no measurements exist. The RTX 4050 Mobile also aligns with a 96-bit memory bus and 192.0 GB/s bandwidth, which is modest but recorded. The N1X 40SM lists a wider 256-bit bus and 273.2 GB/s bandwidth, but without benchmark confirmation, these numbers remain theoretical.

Specification Differences

The two GPUs differ across nearly every specification field. The RTX 4050 Mobile uses the AD107 chip from the Ada Lovelace architecture, while the N1X 40SM uses the GB20B chip from Blackwell 2.0. The RTX 4050 Mobile has 2,560 shading units, 80 texture mapping units, and 48 ROPs. The N1X 40SM has 5,120 shading units, 320 TMUs, and 40 ROPs. The N1X 40SM doubles the shading units and quadruples the TMUs, but has fewer ROPs.

Memory configurations diverge sharply. The RTX 4050 Mobile has 6 GB of GDDR6 on a 96-bit bus, delivering 192.0 GB/s. The N1X 40SM has 128 GB of LPDDR5X on a 256-bit bus, delivering 273.2 GB/s. The N1X 40SM has over 21 times the memory capacity and 42% more bandwidth.

Clock speeds also differ. The RTX 4050 Mobile runs at a base clock of 1455 MHz and a boost of 1755 MHz, with memory at 2000 MHz or 16 Gbps effective. The N1X 40SM has a base of 741 MHz, a boost of 2346 MHz, and memory at 1067 MHz or 8.5 Gbps effective. The N1X 40SM boosts 591 MHz higher but idles at roughly half the base clock.

The bus interface differs: the RTX 4050 Mobile uses PCIe 4.0 x8, while the N1X 40SM uses PCIe 5.0 x16. Both are integrated into the package (IGP slot width) with no power connectors. The RTX 4050 Mobile has a TDP of 50 W, while the N1X 40SM lists TDP as unknown. Display outputs differ: the RTX 4050 Mobile is portable-device dependent, while the N1X 40SM lists a single HDMI output.

Architecture Differences

The architectural gap is substantial. The RTX 4050 Mobile uses the Ada Lovelace architecture on a 5 nm TSMC process with 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9 million per square millimeter. The N1X 40SM uses Blackwell 2.0 on the same 5 nm TSMC process but has an unknown transistor count on a 382 mm² die, which is 2.4 times larger.

Ray tracing and tensor core counts differ. The RTX 4050 Mobile has 20 RT cores and 80 tensor cores. The N1X 40SM has 40 RT cores and 160 tensor cores, doubling both. FP32 and FP16 performance are 1:1 on both parts, but the N1X 40SM lists 24.02 TFLOPS versus 8.986 TFLOPS for the RTX 4050 Mobile. Pixel rate is 84.24 GPixel/s for the RTX 4050 Mobile and 93.84 GPixel/s for the N1X 40SM. Texture rate is 140.4 GTexel/s versus 750.7 GTexel/s, a 5.3x advantage for the N1X 40SM.

API support is the most consequential difference. The RTX 4050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists N/A for all three APIs, meaning it cannot run standard graphics APIs in the database's assessment. The RTX 4050 Mobile is part of the GeForce 40 Mobile generation with a predecessor in GeForce 30 Mobile and a successor in GeForce 50 Mobile. The N1X 40SM has no predecessor or successor listed, and its generation is designated Blackwell IGP (N1x). The RTX 4050 Mobile released in early 2023; the N1X 40SM lists a mid-2026 release date. Both are produced by NVIDIA at TSMC on 5 nm, but the N1X 40SM's larger die and doubled core counts indicate a fundamentally different design target, likely integrated into a system-on-chip rather than a discrete mobile GPU.
