NVIDIA GeForce RTX 5050 Mobile vs NVIDIA N1X 40SM Comparison

The Verdict

The benchmark database records two very different NVIDIA designs under Blackwell 2.0, both on TSMC 5 nm, but they serve entirely separate roles. The GeForce RTX 5050 Mobile is a finished, consumer-facing mobile GPU with active benchmark results. The N1X 40SM is an integrated graphics processor (IGP) with no recorded benchmark scores, no API support data, and a zero average benchmark score. The RTX 5050 Mobile sits at the 83rd percentile among all GPUs in the database, while the N1X 40SM sits at the 50th percentile, which in this case reflects the absence of recorded performance data rather than a measured performance level.

The RTX 5050 Mobile has an average benchmark score of 43,268 across its recorded tests. Its nearest rivals in the database include the Quadro M6000 24 GB at 43,262 (a 0% delta), the Quadro M6000 at 43,301 (0.1% ahead of the RTX 5050), the RTX 4070 SUPER at 43,223 (0.1% behind), and the RTX 4090 Mobile at 43,667 (0.9% ahead). These deltas place the RTX 5050 Mobile in a tight performance cluster. The N1X 40SM has no rivals listed and no average score, so the data cannot place it in any performance hierarchy.

Given the recorded data, the RTX 5050 Mobile is the only one of the two with measurable gaming or compute performance. The N1X 40SM provides no benchmark evidence for any workload. The verdict from the database is straightforward: the RTX 5050 Mobile is the choice for anyone seeking a discrete-class mobile GPU with verified results, while the N1X 40SM lacks the recorded data to support any performance claim. The N1X 40SM does offer a much larger memory pool at 128 GB, but without benchmark scores, the data cannot confirm what that memory delivers in practice.

Architecture Differences

Both GPUs share the Blackwell 2.0 architecture and the TSMC 5 nm process node, but their physical implementations diverge sharply. The RTX 5050 Mobile uses the GB207 chip with a die size of 149 mm² and a transistor count of 16,900 million, yielding a transistor density of 113.4 million transistors per mm². The N1X 40SM uses the GB20B chip with a die size of 382 mm², which is more than twice the area of the GB207. The N1X 40SM transistor count is listed as unknown, so no density comparison can be made from the database.

The shading unit counts differ substantially. The RTX 5050 Mobile has 2,560 shading units, 80 texture mapping units (TMUs), and 32 raster operation units (ROPs). The N1X 40SM has 5,120 shading units, 320 TMUs, and 40 ROPs, meaning it doubles the shader count, quadruples the TMU count, and adds 8 more ROPs. Ray tracing cores scale similarly: the RTX 5050 has 20 RT cores and 80 tensor cores, while the N1X 40SM has 40 RT cores and 160 tensor cores.

Clock behavior also differs. The RTX 5050 Mobile has a base clock of 1020 MHz and a boost clock of 1500 MHz. The N1X 40SM has a lower base clock of 741 MHz but a much higher boost clock of 2346 MHz. The memory subsystems are completely different in type and capacity. The RTX 5050 uses 8 GB of GDDR7 on a 128-bit bus with 1500 MHz memory clock (24 Gbps effective) and a bandwidth of 384.0 GB/s. The N1X 40SM uses 128 GB of LPDDR5X on a 256-bit bus with 1067 MHz memory clock (8.5 Gbps effective) and a bandwidth of 273.2 GB/s.

API support is another major split. The RTX 5050 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 40SM lists all three APIs as N/A in the database. The RTX 5050 has a 50 W TDP, while the N1X 40SM TDP is unknown. Both are classified as IGP slot width with no power connectors, and both use a PCIe 5.0 x16 bus interface. Display outputs differ: the RTX 5050 is portable-device dependent, while the N1X 40SM lists a single HDMI output.

Where Each One Wins

The recorded benchmark data gives the RTX 5050 Mobile two concrete wins: a 3DMark Steel Nomad DX12 score of 2,365 and a Geekbench OpenCL score of 84,171. These are the only performance measurements in the database for either GPU. The N1X 40SM has zero recorded benchmarks, so it cannot win any measured comparison. The data shows the RTX 5050 Mobile as the sole performer in this head-to-head, with both wins belonging to it by default.

The N1X 40SM does win on specifications that are not performance benchmarks. It has a larger memory capacity at 128 GB versus 8 GB, a wider 256-bit memory bus versus 128-bit, and a higher pixel rate at 93.84 GPixel/s versus 48.00 GPixel/s. Its texture rate of 750.7 GTexel/s far exceeds the RTX 5050's 120.0 GTexel/s. Its FP32 compute of 24.02 TFLOPS is more than triple the RTX 5050's 7.680 TFLOPS. These specification advantages are real in the database, but they are not validated by any benchmark score.

The use-case split follows the data. The RTX 5050 Mobile is validated for DirectX 12 workloads (the Steel Nomad test) and OpenCL compute (the Geekbench test). The N1X 40SM has no API support recorded, so the database cannot confirm its suitability for any specific workload. For gaming, the RTX 5050 has the only recorded DX12 result. For general compute, the RTX 5050 has the only OpenCL result. The N1X 40SM's large memory and high raw shader counts suggest potential for data-heavy tasks, but without benchmark data, that potential is unmeasured.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for these two GPUs, and the wins count for each is zero. This means there are no recorded side-by-side test scores to compare. However, the RTX 5050 Mobile does have standalone benchmark results that provide the only performance data available in this comparison.

The 3DMark Steel Nomad DX12 test produced a score of 2,365 for the RTX 5050 Mobile. This is the only DX12 benchmark result between the two GPUs. The N1X 40SM has no DX12 score, and its DirectX support is listed as N/A, so the database cannot confirm it can even run this test. The RTX 5050's Geekbench OpenCL score of 84,171 is the only OpenCL result in this pairing. The N1X 40SM again has no corresponding score.

Relative to the rest of the database, the RTX 5050 Mobile's average score of 43,268 places it within a very tight band of its nearest rivals. The 0.1% delta against the RTX 4070 SUPER (43,223) and the 0.1% delta against the Quadro M6000 (43,301) indicate that the RTX 5050 Mobile performs essentially at parity with those two GPUs. The 0.9% delta against the RTX 4090 Mobile (43,667) is the largest gap in the rival group, but still under a single percentage point. The 0% delta against the Quadro M6000 24 GB (43,262) means the two are statistically indistinguishable in the database.

The N1X 40SM has no rival list and no average score, so it cannot be positioned relative to any other GPU. The data shows no head-to-head wins for either side because no head-to-head tests exist. The practical interpretation is that the RTX 5050 Mobile has measurable performance, while the N1X 40SM does not have any recorded performance to analyze.

Specification Differences

The two GPUs differ across nearly every specification field in the database. The chip names differ: GB207 for the RTX 5050 Mobile versus GB20B for the N1X 40SM.
