PassMark G3D scores 14,195, placing it well above the median GPU in the database. The B570 also posts a PassMark GPU Compute score of 7,281, confirming its ability to handle compute-heavy applications beyond pure graphics rendering.
The B570's advantage extends to legacy API support as well. PassMark DirectX 9 scores 164, DirectX 10 scores 65, DirectX 11 scores 118, and DirectX 12 scores 72. These results show the card handles older titles with ease while maintaining modern API throughput. The PassMark G2D score of 661 indicates strong 2D and desktop compositing performance, useful for productivity and content creation workloads.
The Intel Arc Graphics 2 Xe Mobile wins in the categories of power efficiency and physical footprint, though the database records no benchmark scores to quantify the performance trade-off. Its TDP is 25 W, compared to 150 W for the B570. The mobile part is an IGP with no power connectors, while the B570 requires a single 8-pin connector and a suggested 450 W power supply. The mobile part is built on a 3 nm process from Intel, while the B570 uses a 5 nm process from TSMC. The smaller process node suggests the mobile part achieves its low power draw through architectural efficiency, though the database does not provide measured efficiency figures.
The mobile part's base clock is 300 MHz with a boost of 2500 MHz, matching the B570's boost clock of 2500 MHz. However, the B570 runs at a constant 2500 MHz base and boost, meaning it sustains its peak frequency continuously. The mobile part's 300 MHz base clock indicates it idles much lower, which contributes to its 25 W power envelope. The B570's dual-slot form factor and 272 mm length stand in contrast to the mobile part's IGP design, which occupies no expansion slot and requires no cooling solution beyond what the laptop chassis provides.
The Verdict
The data indicates the Intel Arc B570 is the only viable choice for any workload that requires measurable graphics performance. Its 65th percentile ranking among all GPUs in the database, combined with an average benchmark score of 20,556, places it in the same performance class as the NVIDIA GeForce RTX 3070 Mobile, within 0.1 percent. The B570's nearest rivals all fall within a 0.5 percent band, meaning the B570 is competitive with established mid-range discrete GPUs.
The Intel Arc Graphics 2 Xe Mobile has no recorded benchmark scores, making direct performance comparison impossible from the database. Its 50th percentile ranking is based on specifications alone, and its 256 shading units, 16 TMUs, and 8 ROPs represent a fraction of the B570's resources. The mobile part's 1,280.0 GFLOPS FP32 throughput is roughly one-ninth of the B570's 11.52 TFLOPS. For gaming, rendering, or compute workloads, the B570 is the clear choice.
The mobile part's advantage lies in its integration. At 25 W TDP with no power connectors and no expansion slot requirement, it suits thin-and-light laptops where dedicated graphics is not feasible. The B570 requires a 450 W power supply, a dual-slot chassis, and a PCIe 4.0 x8 slot. For users building a desktop system, the B570 delivers measurable performance. For users purchasing a portable device, the mobile part is the only option in this comparison, but the database does not quantify its real-world performance.
The release timeline also matters. The B570 launched on January 15, 2025, with a launch MSRP of 219 USD, while the mobile part has a release date of April 15, 2026. The mobile part belongs to the Arc Graphics-M generation based on the Wildcat Lake chip, succeeding HD Graphics-M.
