Intel Arc Pro B390 vs NVIDIA GeForce RTX 5050 Mobile Comparison

Where Each One Wins

The Intel Arc Pro B390 and the NVIDIA GeForce RTX 5050 Mobile occupy different positions in the benchmark database, with the data showing a clear split in their intended workloads. The RTX 5050 Mobile holds a decisive advantage in raw graphics performance, as evidenced by its 3DMark Steel Nomad DX12 score of 2365, a result that reflects its dedicated 8 GB GDDR7 memory and 2560 shading units. The Arc Pro B390, by contrast, has no recorded 3DMark result, and its percentile ranking of 50 places it at the median of all GPUs, whereas the RTX 5050 Mobile sits at the 83rd percentile. This gap in percentile ranking indicates that the Intel part is positioned for integrated graphics duty, not discrete-level gaming or professional 3D rendering.

The RTX 5050 Mobile also wins on compute throughput in the Geekbench OpenCL test, scoring 84171. This result, combined with its average benchmark score of 43268, places it in the company of much larger discrete GPUs, including the NVIDIA GeForce RTX 4070 SUPER (within 0.1%) and the RTX 4090 Mobile (0.9% ahead). The Arc Pro B390, with an average benchmark score of 0 and no entries in the database, cannot be compared on the same scale. The data suggests the Intel part is designed for platforms where system memory is shared, as its memory configuration is listed as "System Shared" with bandwidth described as "System Dependent," meaning its performance scales with the host system's memory subsystem rather than a dedicated VRAM pool.

Where the Arc Pro B390 wins is in architectural efficiency and feature parity. Its Xe3-LPG architecture, built on Intel's 3 nm process, delivers a base clock of 300 MHz and a boost clock of 2500 MHz, while the RTX 5050 Mobile runs at 1020 MHz base and 1500 MHz boost. The Intel part also matches the NVIDIA chip in texture rate, both at 120.0 GTexel/s, and exceeds it in pixel rate, 60.00 GPixel/s versus 48.00 GPixel/s. These figures indicate that the Arc Pro B390 is not a slouch in fixed-function throughput; it simply lacks the dedicated memory bandwidth and shader count to compete in sustained 3D workloads. The Intel part also matches the RTX 5050 Mobile on API support, with both listing DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The RTX 5050 Mobile wins on memory capacity and bandwidth outright: 8 GB of GDDR7 on a 128-bit bus delivering 384.0 GB/s, compared to the Arc Pro B390's system-shared memory with no fixed bandwidth figure. The NVIDIA part also has far more shading units (2560 versus 1536), more texture mapping units (80 versus 48), more raster output units (32 versus 24), and more ray tracing cores (20 versus 12). It also includes 80 tensor cores, a feature the Intel part does not list at all. These hardware differences translate directly into the benchmark gap: the RTX 5050 Mobile is built for performance, the Arc Pro B390 for integration.

The Verdict

The data supports a straightforward selection based on workload. The NVIDIA GeForce RTX 5050 Mobile is the only option with recorded benchmark scores, and its 83rd percentile ranking, alongside an average score of 43268, places it among discrete GPUs that historically command a premium. Its nearest rivals include the NVIDIA Quadro M6000 24 GB (0% delta), the NVIDIA Quadro M6000 (0.1% behind), the RTX 4070 SUPER (0.1% ahead), and the RTX 4090 Mobile (0.9% ahead). These comparisons show that the RTX 5050 Mobile delivers performance within a narrow band of much larger and more expensive desktop and mobile parts, making it a sensible choice for any laptop requiring dedicated graphics capability.

The Intel Arc Pro B390, with no benchmark entries and a 50th percentile ranking, is not a competitor in the same performance class. Its 80 W TDP is 30 W higher than the RTX 5050 Mobile's 50 W, yet it still relies on system-shared memory, which is a fundamental bottleneck for graphics workloads. The Intel part is best understood as an integrated graphics processor (IGP) for mobile platforms where a discrete GPU is unnecessary, such as thin-and-light portables focused on productivity, media playback, or light content creation. Its 7.680 TFLOPS FP32 throughput matches the RTX 5050 Mobile exactly, but that figure is theoretical; without dedicated VRAM, real-world sustained performance will depend entirely on the host system's memory bandwidth.

For any user needing confirmed 3D performance, the RTX 5050 Mobile is the data-backed choice. For a system where graphics are secondary and power efficiency is less critical than the 3 nm process might suggest, the Arc Pro B390 offers a capable integrated solution with modern API support. The database does not record any head-to-head benchmark between the two, so the verdict rests on the RTX 5050 Mobile's measured scores and the Arc Pro B390's absence from all recorded tests.

Head-to-Head Benchmarks

The database lists no direct head-to-head benchmark results between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 5050 Mobile. However, the available data allows for an indirect comparison across several metrics. The most significant gap appears in the 3DMark Steel Nomad DX12 test, where the RTX 5050 Mobile scores 2365. The Arc Pro B390 has no result for this test, indicating it was either not run or not competitive enough to record. Similarly, in Geekbench OpenCL, the RTX 5050 Mobile scores 84171, while the Intel part again has no entry.

The compute specifications show a near tie in theoretical FP32 performance: both GPUs list exactly 7.680 TFLOPS. The texture rate is also identical at 120.0 GTexel/s. These equalities suggest that for certain compute or texturing workloads, the two parts could perform similarly, but the RTX 5050 Mobile's dedicated memory and higher shader count would likely sustain that performance longer. The Arc Pro B390's FP16 throughput of 15.36 TFLOPS (2:1 ratio) is double its FP32 rate, whereas the RTX 5050 Mobile's FP16 is 7.680 TFLOPS (1:1 ratio), meaning the Intel part has a theoretical advantage in half-precision workloads, which are common in AI inference. However, the RTX 5050 Mobile counters with 80 tensor cores, which are specifically designed for such tasks and are absent from the Intel part's specification list.

The pixel rate favors the Intel part, 60.00 GPixel/s versus 48.00 GPixel/s, which could translate to better fill-rate-bound scenarios like 2D rendering or certain post-processing effects. The RTX 5050 Mobile counters with a higher memory bandwidth of 384.0 GB/s versus "System Dependent" for the Intel part, which is critical for texture-heavy scenes and high-resolution framebuffers. In ray tracing, the RTX 5050 Mobile's 20 RT cores outnumber the Arc Pro B390's 12, though neither part's ray tracing performance is recorded in the database.

The nearest rivals to the RTX 5050 Mobile provide context for its measured performance. Its average benchmark score of 43268 is nearly identical to the NVIDIA Quadro M6000 24 GB (43262, 0% delta) and the NVIDIA GeForce RTX 4070 SUPER (43223, 0.1% difference). It trails the RTX 4090 Mobile by only 0.9% (43667). These deltas indicate that the RTX 5050 Mobile, despite its modest 50 W TDP and 8 GB memory, delivers performance on par with GPUs that have far higher power budgets and larger memory pools. The Arc Pro B390 has no such comparison group, reinforcing its status as an integrated solution rather than a discrete competitor.
