Intel Arc B370 vs Intel Arc Graphics 2 Xe Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains only one benchmark result for the Intel Arc B370, the 3DMark Steel Nomad DX12 test, with a score of 1184. The Intel Arc Graphics 2 Xe Mobile has no recorded benchmark scores in the database, so direct numerical comparison is limited to the single available data point. The Arc B370 sits at the 5th percentile among all GPUs, while the Arc Graphics 2 Xe Mobile holds the 50th percentile, though the latter figure is not tied to any measured score.

Against its nearest rivals, the Arc B370's 1184 score places it marginally behind the ATI Mobility Radeon HD 5570, which averages 1186, a difference of only 0.2 percent. It trails the ATI Radeon HD 5770 by 0.5 percent (1190 average) and the AMD Radeon HD 7650M by 0.7 percent (1192 average). The Arc B370 leads the AMD FirePro M2000 by 1.4 percent, as that GPU averages 1168. These deltas are small, indicating that the Arc B370 clusters tightly with a group of older discrete and mobile graphics solutions in raw DX12 throughput.

The absence of any head-to-head benchmark entries means the database records no direct comparison between the Arc B370 and the Arc Graphics 2 Xe Mobile on any specific test. The wins counter shows zero for both parts. This is a case where architectural specifications must carry the analytical weight, since measured performance data exists for only one of the two products.

Where Each One Wins

The Intel Arc B370 wins on raw computational throughput based on its specification sheet. It uses 1280 shading units, 40 texture mapping units, and 20 raster output units, delivering 48.00 GPixel/s pixel fill rate and 96.00 GTexel/s texture fill rate. Its FP32 compute reaches 6.144 TFLOPS, and FP16 reaches 12.29 TFLOPS with a 2:1 ratio. The 10 ray tracing cores provide hardware acceleration for ray-traced workloads. These numbers indicate a part designed for significantly heavier graphics loads than its mobile counterpart.

The Intel Arc Graphics 2 Xe Mobile wins on clock speed and efficiency of scale. Its boost clock reaches 2500 MHz, 100 MHz higher than the Arc B370's 2400 MHz boost. It uses 256 shading units, 16 TMUs, and 8 ROPs, with a 20.00 GPixel/s pixel rate and 40.00 GTexel/s texture rate. FP32 compute is 1,280.0 GFLOPS, and FP16 is 2.560 TFLOPS. With only 2 ray tracing cores, it offers a lighter implementation of the same Xe3-LPG architecture. The mobile part is built for lower absolute workloads, not for competing with the B370 on peak throughput.

In use-case terms, the Arc B370 suits applications that demand high pixel throughput, dense texture sampling, and substantial ray tracing capability. The Arc Graphics 2 Xe Mobile fits scenarios where modest graphics acceleration is sufficient and the lower shading unit count aligns with lighter display and compute duties. Both parts share a 25 W TDP, so the B370 achieves roughly 4.8 times the FP32 throughput of the mobile part within the same power envelope. That efficiency gap is the clearest differentiator in the recorded data.

Specification Differences

The two GPUs differ across nearly every compute resource. The Arc B370 uses 1280 shading units versus 256 on the mobile part, 40 TMUs versus 16, and 20 ROPs versus 8. Ray tracing cores number 10 on the B370 and 2 on the mobile part. Pixel rate is 48.00 GPixel/s versus 20.00 GPixel/s, and texture rate is 96.00 GTexel/s versus 40.00 GTexel/s. FP32 throughput is 6.144 TFLOPS versus 1,280.0 GFLOPS. FP16 is 12.29 TFLOPS versus 2.560 TFLOPS, both with a 2:1 ratio.

Boost clocks differ: 2400 MHz on the B370 and 2500 MHz on the mobile part. Base clocks are identical at 300 MHz. Both use system shared memory with system dependent bandwidth, so no memory size, type, or bus width differences exist in the records. Both integrate as IGP with no power connectors and portable device dependent display outputs.

Release dates differ. The Arc B370 launched on 2026-01-26, and the Arc Graphics 2 Xe Mobile launched on 2026-04-15. The mobile part lists its predecessor as HD Graphics-M, while the B370 has no predecessor recorded. Both are marked as Active production status.

Architecture Differences

Both GPUs share the Xe3-LPG architecture and a 3 nm process node at Intel's foundry. The chip designs differ: the B370 uses Panther Lake, and the mobile part uses Wildcat Lake. The B370 belongs to the Arc Graphics-M (Panther Lake) generation, while the mobile part belongs to Arc Graphics-M (Wildcat Lake).

Transistor counts and die sizes are listed as unknown for both, so no comparison is possible there. The B370 carries 10 ray tracing cores versus 2 on the mobile part, indicating a much larger ray tracing pipeline. Tensor core counts are null for both, so no AI acceleration comparison can be made from the data.

API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 for both. The architecture is the same, but the resource allocation differs dramatically. The B370 scales up every execution unit category, while the mobile part scales down for lower power and lighter workloads. Both run at the same 25 W TDP, which suggests the mobile part achieves its lower throughput with fewer active units rather than reduced clock speed, since its boost clock is actually higher.

The Verdict

The data points to a clear division of roles. The Intel Arc B370 is the higher-performance part across every measured specification except boost clock. Its 6.144 TFLOPS FP32 output, 48.00 GPixel/s pixel rate, and 10 ray tracing cores make it suitable for graphics workloads that require substantial rasterization and ray tracing throughput. The 1184 score in 3DMark Steel Nomad places it in the 5th percentile of all GPUs, which indicates that while it is not a high-end part, it delivers measurable DX12 performance with a tight grouping around older discrete GPUs like the ATI Radeon HD 5770 and AMD Radeon HD 7650M.

The Intel Arc Graphics 2 Xe Mobile has no benchmark scores, so its performance position cannot be confirmed from measured data. Its specification sheet shows 256 shading units, 8 ROPs, 2 ray tracing cores, and 1,280.0 GFLOPS FP32. Within the same 25 W TDP and 3 nm process, this is a deliberately reduced configuration. The higher boost clock of 2500 MHz does not compensate for the 5 times fewer shading units and 5 times fewer ray tracing cores relative to the B370.

For users selecting between these two, the B370 is the choice when graphics compute density matters. It offers nearly five times the FP32 throughput and substantially higher pixel and texture rates within the same power budget. The mobile part is the choice when the workload is light and the lower resource count is acceptable, though no benchmark evidence in the database supports a performance claim for it. The 50th percentile ranking listed for the mobile part is not backed by any recorded score, and the B370's 5th percentile is backed by a single 1184 result. The verdict from the data is straightforward: the Arc B370 is the stronger graphics processor, and the Arc Graphics 2 Xe Mobile is a smaller implementation of the same architecture for less demanding tasks.
