The Verdict

The data presents a stark contrast between these two integrated graphics solutions. The Arc B370 is designed for users who need actual 3D rendering capability within a Panther Lake platform, while the Arc Graphics 1 Xe Mobile serves as a basic display solution for Wildcat Lake systems.

Benchmark results indicate the Arc B370 achieves a 3DMark Steel Nomad score of 1184, which places it at the 5th percentile of all GPUs. Its nearest rivals show a tight cluster: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% ahead), the ATI Radeon HD 5770 scores 1190 (0.5% ahead), and the AMD Radeon HD 7650M scores 1192 (0.7% ahead). The AMD FirePro M2000 trails at 1168, putting the B370 1.4% ahead. This suggests the B370 sits in a narrow performance band among older discrete mobile GPUs.

The Arc Graphics 1 Xe Mobile has no recorded benchmark scores, making direct performance comparison impossible. Its specifications, however, show a 90% reduction in shading units (128 versus 1280) and a 95% reduction in ROPs (4 versus 20). The FP32 compute drops from 6.144 TFLOPS to 588.8 GFLOPS, a 10-fold difference.

For system integrators, the choice depends entirely on the target workload. The Arc B370 can handle light gaming and accelerated graphics tasks at its measured performance level. The Arc Graphics 1 Xe Mobile, with its single Xe core configuration, is suited for basic desktop composition, video playback, and power-efficient operation where 3D performance is not a requirement.

Head-to-Head Benchmarks

The head-to-head benchmark table contains no entries, meaning no direct comparative tests have been recorded in the database. The only available benchmark belongs to the Arc B370: a 3DMark Steel Nomad DX12 score of 1184.

This single data point allows for relative positioning against the B370's nearest rivals. The ATI Mobility Radeon HD 5570 scores 1186, a delta of -0.2% from the B370, indicating the two perform nearly identically. The ATI Radeon HD 5770 scores 1190, 0.5% higher. The AMD Radeon HD 7650M scores 1192, 0.7% higher. The AMD FirePro M2000 scores 1168, which is 1.4% lower than the B370.

These tight margins, all within 2.1% of each other, suggest the B370's performance class is well established. The B370 is neither a standout nor a laggard within this group. It sits in the middle of a cluster of older discrete GPUs, which is notable for an integrated part.

The Arc Graphics 1 Xe Mobile's absence from the benchmark database means no wins can be attributed to it. Its 50th percentile ranking appears to be a placeholder based on its specification sheet rather than measured performance. The B370's 5th percentile ranking reflects its actual Steel Nomad score, which is low relative to the entire GPU landscape.

Specification Differences

The two GPUs differ across nearly every computational metric. The Arc B370 features 1280 shading units, 40 TMUs, and 20 ROPs. The Arc Graphics 1 Xe Mobile features 128 shading units, 8 TMUs, and 4 ROPs. These represent 10x, 5x, and 5x differences respectively.

Ray tracing cores also differ significantly: the B370 has 10, the Arc Graphics 1 Xe Mobile has 1. This is a 10x difference in ray tracing capability.

Pixel rate on the B370 is 48.00 GPixel/s versus 9.200 GPixel/s on the mobile part, a factor of approximately 5.2. Texture rate is 96.00 GTexel/s versus 18.40 GTexel/s, also a factor of approximately 5.2.

FP32 compute on the B370 is 6.144 TFLOPS. The Arc Graphics 1 Xe Mobile delivers 588.8 GFLOPS, which is 10.4 times lower. FP16 performance follows a similar pattern: 12.29 TFLOPS (2:1) on the B370 versus 1,177.6 GFLOPS (2:1) on the mobile GPU.

Boost clocks differ by 100 MHz: 2400 MHz for the B370, 2300 MHz for the Arc Graphics 1 Xe Mobile. Base clocks are identical at 300 MHz.

Both have 25 W TDP, IGP slot width, no power connectors, and system shared memory. Both use the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are portable device dependent for both.

Architecture Differences

Both GPUs share the Xe3-LPG architecture and 3 nm process node, with Intel as the foundry. The chip designs, however, differ substantially. The Arc B370 uses the Panther Lake chip, while the Arc Graphics 1 Xe Mobile uses the Wildcat Lake chip. These belong to different generations within the Arc Graphics-M family.

The shading unit count difference of 1280 versus 128 indicates the B370 uses a substantially larger GPU die configuration within the Panther Lake package. The Wildcat Lake chip's smaller graphics block appears designed for minimal power draw and die area, while still maintaining the Xe3-LPG architecture's feature set.

Both parts maintain full API support including DirectX 12 Ultimate, which requires hardware support for mesh shaders, variable rate shading, and ray tracing. The B370's 10 ray tracing cores versus the mobile part's single core suggests the B370 can handle ray tracing workloads at much higher throughput, though neither is a high-end solution in absolute terms.

The memory architecture is identical in type: system shared with system dependent bandwidth. Neither part has dedicated video memory, so performance will scale with system memory configuration and CPU memory controller capabilities.

Transistor counts and die sizes are not recorded in the database for either GPU. The production status for both is listed as Active, with the B370 releasing on 2026-01-26 and the Arc Graphics 1 Xe Mobile on 2026-04-15. The mobile part lists its predecessor as HD Graphics-M, while the B370 has no predecessor recorded.

Where Each One Wins

The Arc B370 wins in every measurable computational category. Its 3DMark Steel Nomad score of 1184 provides a concrete performance data point. The nearest rival comparison shows it within 1.4% of the AMD FirePro M2000 (which it beats) and within 0.7% of the AMD Radeon HD 7650M (which beats it). This places the B370 among older discrete mobile GPUs, a meaningful achievement for an integrated part.

The B370's 6.144 TFLOPS FP32 performance and 96.00 GTexel/s texture rate make it suitable for light gaming, GPU-accelerated encoding, and compute workloads that benefit from parallel processing. Its 10 ray tracing cores enable hardware ray tracing, albeit at modest performance levels given its 5th percentile overall ranking.

The Arc Graphics 1 Xe Mobile wins in the absence of competition: it has no recorded benchmarks, so no measured losses. Its specification position at the 50th percentile suggests the database ranks it as an average GPU overall, though this appears based on its feature set rather than performance. Its 588.8 GFLOPS FP32 output indicates basic 2D acceleration, video decode, and display output duties.

For power-sensitive designs, both parts share a 25 W TDP. The mobile part's smaller GPU block (128 shading units versus 1280) likely consumes less power within that envelope, though the database does not record actual power measurements.

The Wildcat Lake chip with its single Xe core appears suited for entry-level laptops where battery life and thermal management take priority over graphics performance. The Panther Lake chip with the B370's 10-core GPU configuration is better positioned for thin-and-light systems that need occasional 3D acceleration beyond basic desktop rendering.

The release date gap of 2026-01-26 versus 2026-04-15 gives the B370 an earlier availability. The mobile part's predecessor designation of HD Graphics-M indicates a lineage from Intel's older integrated graphics lineup, while the B370 has no recorded predecessor, suggesting it represents a new performance tier within the Panther Lake family.
