Intel Arc B370 vs Intel Arc Graphics 32EU Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the Intel Arc B370 and the Intel Arc Graphics 32EU in the 3DMark Steel Nomad DX12 test. The Intel Arc B370 scores 1184, while the Intel Arc Graphics 32EU scores 733. This gives the B370 a decisive 61.5% advantage in the benchmark. The win count in the head-to-head comparison stands at 1 for the B370 and 0 for the 32EU.

The B370's score of 1184 places it at the 5th percentile among all GPUs in the database. Its nearest rivals include the ATI Mobility Radeon HD 5570 at 1186, which is 0.2% higher, and the ATI Radeon HD 5770 at 1190, which is 0.5% higher. The AMD FirePro M2000 trails at 1168, which is 1.4% behind the B370. These deltas are narrow, indicating that the B370 sits in a tightly clustered performance band where small margins separate competitors.

The Intel Arc Graphics 32EU scores 733, which places it at the 3rd percentile among all GPUs. Its nearest rivals show a different pattern. The Intel Arc Graphics 24EU and the Intel Arc Graphics 64EU both score exactly 733, resulting in a 0% delta. The AMD Radeon HD 6470M scores 723, which is 1.4% behind, while the NVIDIA GeForce GT 415M scores 751, which is 2.4% ahead. The 32EU therefore sits in a group where the 64EU variant offers no measurable advantage in this test, and the 24EU variant performs identically.

The 61.5% delta between the two compared parts is substantial. The B370 delivers nearly two-thirds more performance in this DirectX 12 workload. That gap is far larger than the differences seen among the nearest rivals for either product, which stay within a few percentage points. The benchmark results indicate that the B370 operates in a different performance class entirely, despite both being integrated graphics solutions from Intel.

Architecture Differences

The Intel Arc B370 is built on the Panther Lake chip using the Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel's foundry. The Intel Arc Graphics 32EU uses the Arrow Lake-S chip with the Xe-LPG architecture, belonging to the Arc Graphics-M (Arrow Lake) generation. It is also on a 3 nm process, but the foundry is TSMC.

The transistor counts and die sizes differ sharply. The B370 has an unknown transistor count and die size, while the 32EU is documented with 17,800 million transistors on a 243 mm² die, yielding a transistor density of 73.3M per mm². The B370's architecture is newer, as the Panther Lake generation follows the Arrow Lake generation in the database.

Core configuration shows a major scaling difference. The B370 has 1280 shading units, 40 texture mapping units, and 20 raster output units. The 32EU has 256 shading units, 16 TMUs, and 8 ROPs. The B370 also includes 10 ray tracing cores, while the 32EU lists no ray tracing cores in the data. Neither part has documented tensor cores.

Clock behavior differs as well. Both have a 300 MHz base clock, but the B370 boosts to 2400 MHz, while the 32EU boosts to 1950 MHz. The B370's higher core count combined with a higher boost clock explains the large benchmark gap. The B370 achieves a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The 32EU delivers 15.60 GPixel/s and 31.20 GTexel/s. Floating point performance follows the same pattern: the B370 reaches 6.144 TFLOPS in FP32 and 12.29 TFLOPS in FP16 (2:1), while the 32EU manages 998.4 GFLOPS in FP32 and 1.997 TFLOPS in FP16 (2:1).

The memory subsystem is identical in both: system shared memory, system shared type, system shared bus width, and system dependent bandwidth. Neither has dedicated video memory.

Power and integration differ notably. The B370 has a 25 W TDP, while the 32EU has a 65 W TDP. Despite the higher TDP, the 32EU delivers less performance, indicating that the B370's newer architecture and higher clock efficiency are significant factors. Both use an IGP slot width, but the bus interface differs: the B370 uses IGP, while the 32EU uses Ring Bus. The B370 lists no power connectors, while the 32EU has no power connector data recorded.

Display outputs also differ. The B370's outputs are portable device dependent, while the 32EU's are motherboard dependent. This reflects their differing target platforms: Panther Lake for mobile devices, Arrow Lake-S for desktop motherboards.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data shows a clear performance hierarchy. The Intel Arc B370 dominates the Intel Arc Graphics 32EU in every measurable compute metric. The B370's 61.5% lead in the Steel Nomad test, combined with higher shading unit counts, higher boost clocks, and the inclusion of ray tracing cores, places it firmly ahead.

The B370 achieves this with a 25 W TDP, which is 40 W lower than the 32EU's 65 W TDP. This efficiency advantage comes from the newer Xe3-LPG architecture and the Intel foundry process, both of which differ from the 32EU's Xe-LPG architecture and TSMC fabrication.

The 32EU is not without its place. Its 733 score ties exactly with the Intel Arc Graphics 24EU and the 64EU in the database, indicating that within that product family, the 32EU offers no measurable advantage over lower or higher EU counts in this specific workload. Its nearest rival, the NVIDIA GeForce GT 415M, is only 2.4% faster, suggesting the 32EU sits near the bottom of the GPU performance spectrum. The B370, by contrast, sits within 0.7% of several ATI/AMD parts from a different era, showing it competes in a higher tier.

For users relying on integrated graphics, the B370 is the stronger choice when performance matters, as it delivers roughly 61.5% more benchmark score while drawing less power. The 32EU makes sense only in systems where the Arrow Lake-S platform and its Ring Bus interface are required, or where the lower absolute performance is acceptable. The release dates reinforce this: the B370 arrived later, on 2026-01-26, while the 32EU launched on 2024-10-23. The newer part brings the architectural improvements that the benchmark data confirms.
