Analysis: Intel Arc B390 vs NVIDIA N1 16SM

Head-to-Head Benchmarks

Direct benchmark comparisons between the Intel Arc B390 and the NVIDIA N1 16SM are limited by the available recorded data. The Intel Arc B390 has a single measured benchmark result: a 3DMark Steel Nomad DX12 score of 1482 points. This places it in the 9th percentile of all GPUs in the database, indicating that it outperforms only a small fraction of the entire GPU landscape. The NVIDIA N1 16SM, by contrast, has no recorded benchmark scores in the database, meaning direct head-to-head numerical comparisons cannot be established from existing measurements.

The Intel Arc B390's nearest rivals in the database are all older NVIDIA discrete GPUs. It sits 1.3% ahead of the GeForce GT 520MX, which averages 1463 points. It is 1.5% ahead of the GeForce 800M, which averages 1460 points. The gap widens slightly against the GeForce GT 625 OEM, which averages 1446 points, putting the Arc B390 2.5% ahead. Against the GeForce GT 710, which averages 1443 points, the Arc B390 leads by 2.7%. These deltas are modest in absolute terms, but they show the Arc B390 clustering tightly with low-end GPUs from past generations rather than competing with modern mid-range or high-end parts.

The NVIDIA N1 16SM does not have any nearest rivals listed in the database, and its average benchmark score is recorded as zero. This absence of data means the N1 16SM cannot be positioned against the Arc B390 using measured performance figures. The database records the N1 16SM at the 50th percentile of all GPUs, but this percentile is derived from its placement among other entries, not from an actual benchmark run. With no score to compare, any assertion about which GPU is faster in synthetic workloads remains unsupported by the available measurements.

The head-to-head benchmark list between the two products is empty, and the win counts for both items are zero. This is a case where the data simply does not contain a direct comparison. The only concrete numeric anchor is the Arc B390's 1482 score in 3DMark Steel Nomad DX12, which at least provides a reference point for its absolute performance level. The N1 16SM offers no such anchor.

The Verdict

Based strictly on the recorded data, the Intel Arc B390 is the only one of the two with a measurable performance profile. Its 3DMark Steel Nomad DX12 score of 1482 points, while low in the overall distribution (9th percentile), at least confirms that it can execute a modern DirectX 12 Ultimate workload and produce a result. The NVIDIA N1 16SM has no benchmark scores, no nearest rivals, and no average score, so there is no evidence in the database that it performs at any particular level in gaming or compute tests.

The Arc B390 also carries a defined feature set for graphics work: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. The N1 16SM lists DirectX, OpenGL, and Vulkan as N/A. For any application relying on these APIs, the Arc B390 is the only option that the data confirms will run. The N1 16SM's API support is unlisted, which suggests it may not be intended for traditional graphics workloads, or that the database has not recorded its capabilities.

For users who need a GPU with confirmed API compatibility and a measured 3DMark result, the Arc B390 is the safer choice from the available data. For users who are considering the N1 16SM, the database provides no performance evidence to justify selection over the Arc B390. The N1 16SM does offer substantially more raw hardware resources, including 2048 shading units versus 1536, 128 texture mapping units versus 48, and 16 ray tracing cores versus 12, but without benchmark scores, these specifications do not translate into verified performance.

Where Each One Wins

Intel Arc B390 wins on measured performance evidence. The database contains a real benchmark score for this GPU: 1482 in 3DMark Steel Nomad DX12. It also records a full set of graphics API support, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Any workload that requires these APIs can be assumed to run on the Arc B390 based on the recorded data.

NVIDIA N1 16SM wins on hardware resource counts. It has more shading units (2048 versus 1536), more texture mapping units (128 versus 48), more ray tracing cores (16 versus 12), and a much larger memory configuration (128 GB of LPDDR5X on a 256-bit bus versus system shared memory). It also includes 64 tensor cores, a feature the Arc B390 does not list at all. These are specification advantages, not measured performance advantages. The database does not confirm that they translate into faster results in any test.

Intel Arc B390 wins on API coverage. The Arc B390 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The N1 16SM lists all three as N/A. For software that depends on these interfaces, the Arc B390 is the only viable option per the data.

NVIDIA N1 16SM wins on memory capacity and bandwidth. The N1 16SM has 128 GB of dedicated LPDDR5X memory with 273.2 GB/s of bandwidth. The Arc B390 uses system shared memory with system dependent bandwidth. For workloads that require large resident datasets and consistent memory throughput, the N1 16SM's dedicated memory is a structural advantage.

Intel Arc B390 wins on process node. The Arc B390 is fabricated on a 3 nm process, while the N1 16SM uses a 5 nm process. The Arc B390 also has a much smaller die size potential given its transistor count is unknown, but the N1 16SM has a recorded die size of 382 mm². The Arc B390's die size is not listed.
