Intel Arc Pro B50 vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head comparison results between the Intel Arc Pro B50 and the NVIDIA N1X 48SM. The recorded data for the Arc Pro B50 includes multiple test scores, while the N1X 48SM has an empty benchmark array. This absence of direct measurements means a conventional win/loss tally cannot be generated. The Arc Pro B50's recorded scores include a Passmark G3D score of 12553, a Passmark GPU Compute score of 6037, and a 3DMark Steel Nomad DX12 score of 1604. Its average benchmark score across all recorded tests is 2660, placing it in the 17th percentile of all GPUs in the database. The N1X 48SM has an average benchmark score of 0 and sits in the 50th percentile, but this percentile is derived from no actual benchmark data. The data indicates that the Arc Pro B50 has measurable performance in DirectX 10, 11, 12, and 9 tests, with scores of 58, 100, 64, and 144 respectively, along with a 2D graphics score of 717. Without any benchmark results for the N1X 48SM, comparative performance metrics cannot be established. The nearest rivals for the Arc Pro B50 in the database are the NVIDIA GeForce GT 1030 with an average score of 2662 and a delta of -0.1%, the NVIDIA Quadro K1100M at 2664 with a delta of -0.2%, the NVIDIA GeForce GT 440 at 2645 with a delta of 0.6%, and the NVIDIA GeForce RTX 5070 SUPER at 2690 with a delta of -1.1%. These deltas show the Arc Pro B50 performing within a narrow band of about 1% of these rivals, indicating its average benchmark score is closely clustered with those specific products.

Where Each One Wins

The Arc Pro B50 demonstrates clear wins in the recorded benchmark suite. Its Passmark G3D score of 12553 indicates substantial 3D rendering capability, while its GPU compute score of 6037 shows strong general-purpose processing. The DirectX 9 score of 144 is the highest among its DirectX tests, suggesting particular strength in legacy API workloads. The DirectX 11 score of 100 exceeds its DirectX 12 score of 64 and DirectX 10 score of 58, which indicates that the card performs better under older DirectX versions than under the latest one. The 3DMark Steel Nomad DX12 score of 1604 provides a modern DX12 data point, but it is the only such test recorded. The N1X 48SM has no benchmark wins because no benchmark data exists for it in the database. Its wins cannot be assessed or enumerated. The data shows the Arc Pro B50 as the only unit with measurable performance, while the N1X 48SM remains uncharacterized by any workload. For use-case split, the Arc Pro B50 shows strengths in 3D graphics rendering, compute workloads, and legacy DirectX applications. The N1X 48SM cannot be assigned any use-case strengths based on the absence of data. The recorded data does not indicate any scenario where the N1X 48SM outperforms the Arc Pro B50, simply because no comparison is possible with zero benchmark entries.

The Verdict

The recorded data shows the Intel Arc Pro B50 as a fully characterized discrete GPU with a complete set of benchmark scores, a defined thermal envelope of 70 W, and a launch MSRP of 349 USD. Its performance, as measured by an average benchmark score of 2660, places it in the 17th percentile of all GPUs, with direct rivals within a 1% delta range. The NVIDIA N1X 48SM, by contrast, has no benchmark data, an average score of 0, and no launch MSRP. Its architecture indicates a high specification count with 6144 shading units, 192 tensor cores, and 128 GB of LPDDR5X memory, but none of this is reflected in any measured performance. The N1X 48SM's 50th percentile ranking in the database appears unsupported by actual test results. For any performance-based comparison, the Arc Pro B50 is the only unit with empirical evidence. The N1X 48SM's specifications show it has higher theoretical throughput in FP32 (28.83 TFLOPS vs 10.65 TFLOPS), more memory (128 GB vs 16 GB), and wider memory bandwidth (273.2 GB/s vs 224.0 GB/s), but these figures remain unverified by benchmarks. The Arc Pro B50's dual-slot form factor, PCIe 5.0 x8 interface, and four mini-DisplayPort outputs make it a practical add-in card. The N1X 48SM is an IGP with a single HDMI output, designed for integration rather than discrete installation. The data as recorded supports the Arc Pro B50 for users requiring measurable, benchmarked performance in standard APIs. The N1X 48SM cannot be recommended for any specific workload based on the absence of benchmark evidence. Its architectural numbers are impressive on paper, but the database contains no validation of those numbers in practice. The verdict from the data is straightforward: the Arc Pro B50 is the only GPU with demonstrated performance, while the N1X 48SM remains an unmeasured specification sheet.
