Intel Arc B370 vs Intel Arc Graphics 64EU Mobile Comparison

Head-to-Head Benchmarks

The direct benchmark comparison between the Intel Arc B370 and the Intel Arc Graphics 64EU Mobile is limited by data availability. The database records a single benchmark result for the Arc B370: a 3DMark Steel Nomad DX12 score of 1184 points. The Arc Graphics 64EU Mobile has no recorded benchmark scores in the database, with an average benchmark score of zero and no entries in its nearest rivals list. Consequently, the head-to-head comparison relies entirely on the Arc B370's measured performance profile and its positioning against other GPUs in the database.

The Arc B370's 1184-point score places it at the 5th percentile among all GPUs tracked by the database. This indicates that 95% of recorded GPUs outperform it in the Steel Nomad DX12 test. Its nearest rivals in the database all score within a narrow band. The ATI Mobility Radeon HD 5570 averages 1186 points, a 0.2% difference from the Arc B370. The ATI Radeon HD 5770 averages 1190 points, 0.5% ahead. The AMD Radeon HD 7650M averages 1192 points, 0.7% ahead. The AMD FirePro M2000 averages 1168 points, which is 1.4% behind the Arc B370. These delta values show that the Arc B370 sits in a tight performance cluster where the spread between the fastest and slowest rival is only 24 points, roughly 2%. The Arc B370 effectively trades places with the AMD FirePro M2000, delivering slightly higher performance, while trailing the other three rivals by less than one percent.

Because the Arc Graphics 64EU Mobile has no benchmark entries, the database cannot compute any wins for either product in a head-to-head test. The wins counter for both items is zero. The performance relationship between these two Intel graphics solutions must be inferred from their architectural specifications rather than from direct measurements.

Architecture Differences

The two GPUs come from different Intel generations and process nodes. The Arc B370 uses the Panther Lake chip built on Intel's 3 nm process, with the Xe3-LPG architecture. The Arc Graphics 64EU Mobile uses the Meteor Lake chip built on Intel's 10 nm process, with the Xe-LPG architecture. This process difference is substantial: the Arc B370's 3 nm node represents a newer manufacturing technology compared to the 10 nm node of the Meteor Lake part. Both chips are fabricated by Intel.

The core configurations differ significantly. The Arc B370 contains 1280 shading units, 40 texture mapping units, and 20 raster operations units. It also includes 10 ray tracing cores. The Arc Graphics 64EU Mobile contains 512 shading units, 32 TMUs, and 16 ROPs, with no ray tracing cores listed. The Arc B370 therefore has 2.5 times the shading units, 1.25 times the TMUs, and 1.25 times the ROPs of the Arc Graphics 64EU Mobile. The presence of dedicated ray tracing hardware in the Arc B370 is a functional advantage that the Meteor Lake part lacks entirely.

Clock speeds also diverge. Both GPUs share a 300 MHz base clock, but the boost clock differs: the Arc B370 boosts to 2400 MHz, while the Arc Graphics 64EU Mobile boosts to 1750 MHz. The Arc B370's boost clock is 650 MHz higher, a 37% increase over the older part. The combination of more shading units and a higher boost clock produces a large gap in raw compute throughput. The Arc B370 delivers 6.144 TFLOPS of FP32 performance, while the Arc Graphics 64EU Mobile delivers 1.792 TFLOPS. The Arc B370 is 3.4 times faster in FP32. In FP16, the Arc B370 achieves 12.29 TFLOPS, compared to 3.584 TFLOPS for the Arc Graphics 64EU Mobile, again a 3.4 times advantage. Both figures are expressed with a 2:1 ratio for FP16 relative to FP32.

Pixel and texture rates follow the same pattern. The Arc B370 has a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The Arc Graphics 64EU Mobile has a pixel rate of 28.00 GPixel/s and a texture rate of 56.00 GTexel/s. The Arc B370's pixel rate is 1.7 times higher, and its texture rate is 1.7 times higher. These rates derive from the combination of core counts and clock speeds.

Memory architecture is identical in type: both use system shared memory with a system dependent bandwidth and a system shared bus width. Neither has dedicated video memory. The TDP values differ notably: the Arc B370 is rated at 25 W, while the Arc Graphics 64EU Mobile is rated at 65 W. This means the newer part delivers substantially higher performance while consuming less than half the power budget. The bus interface also differs. The Arc B370 uses an IGP interface, while the Arc Graphics 64EU Mobile uses a Ring Bus interface. Both are integrated graphics solutions with an IGP slot width and no external power connectors. Display outputs for both are listed as portable device dependent.

API support shows a small difference. The Arc B370 supports DirectX 12 Ultimate (12_2), while the Arc Graphics 64EU Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The newer part has the more advanced DirectX feature level.

Where Each One Wins

The Arc B370 wins in every measured compute and throughput category. Its FP32 throughput of 6.144 TFLOPS is 3.4 times that of the Arc Graphics 64EU Mobile's 1.792 TFLOPS. Its FP16 throughput of 12.29 TFLOPS is similarly 3.4 times the older part's 3.584 TFLOPS. The Arc B370's pixel rate of 48.00 GPixel/s exceeds the 28.00 GPixel/s of the Arc Graphics 64EU Mobile by a factor of 1.7. Its texture rate of 96.00 GTexel/s exceeds 56.00 GTexel/s by the same factor. The Arc B370 also has 2.5 times the shading units, 1.25 times the TMUs, and 1.25 times the ROPs. It adds 10 ray tracing cores where the Arc Graphics 64EU Mobile has none.

The Arc B370's advantage extends to power efficiency. At 25 W TDP, it delivers 6.144 TFLOPS, which is 0.246 TFLOPS per watt. The Arc Graphics 64EU Mobile at 65 W TDP delivers 1.792 TFLOPS, which is 0.028 TFLOPS per watt. The newer part is approximately 8.9 times more efficient on a per-watt basis, derived from the recorded TDP and FP32 figures.

The Arc Graphics 64EU Mobile does hold a few structural advantages. Its 65 W TDP suggests it is designed for a different thermal envelope, possibly for systems that can accommodate higher power draw. Its predecessor is listed as HD Graphics-M, indicating it has a prior generation to build upon. Its release date of 2023-12-13 means it has been on the market longer than the Arc B370, which was released on 2026-01-26. The Arc Graphics 64EU Mobile also sits at the 50th percentile among all GPUs in the database, compared to the Arc B370's 5th percentile. However, this percentile figure is based on the Arc Graphics 64EU Mobile having no recorded benchmark scores, so it reflects the database's distribution of scores rather than a measured performance result. The Arc B370 has an actual measured score, whereas the Arc Graphics 64EU Mobile does not.

The Arc B370 also supports DirectX 12 Ultimate (12_2), which enables features that the DirectX 12 (12_1) support of the Arc Graphics 64EU Mobile cannot access. For workloads that rely on advanced DirectX 12 Ultimate features, the Arc B370 is the only option of the two.

The Verdict

The data presents a clear separation between these two Intel integrated graphics solutions. The Intel Arc B370 is the stronger performer by every measurable specification in the database. It has more shading units, more TMUs, more ROPs, dedicated ray tracing cores, a higher boost clock, and a newer 3 nm process node. Its FP32 throughput of 6.144 TFLOPS is 3.4 times the 1.792 TFLOPS of the Arc Graphics 64EU Mobile. Its pixel rate and texture rate are both 1.7 times higher. These are substantial, not marginal, differences.

The Arc B370 also achieves this superiority while consuming 25 W, which is less than half of the 65 W TDP of the Arc Graphics 64EU Mobile. For systems constrained by power budgets, the newer part is clearly preferable. Its DirectX 12 Ultimate support adds another capability that the older part cannot offer.

The Arc Graphics 64EU Mobile has no recorded benchmark scores, so the database cannot confirm any performance advantage for it. Its 50th percentile ranking is a statistical artifact of having no score entries, whereas the Arc B370's 5th percentile is based on an actual measured 1184-point result in 3DMark Steel Nomad DX12. The Arc B370's nearest rivals all score within 1.4% of it, showing that it lands in a competitive cluster with older ATI and AMD parts, but those rivals are from a much older era.

The release dates reinforce the generational gap. The Arc Graphics 64EU Mobile launched on 2023-12-13, and the Arc B370 launched on 2026-01-26. The newer part replaces the older one in Intel's integrated graphics lineup for different process nodes. The predecessor field for the Arc Graphics 64EU Mobile is HD Graphics-M, confirming it had a lineage, while the Arc B370 has no predecessor listed, suggesting it represents a new designation.

For systems that need maximum integrated graphics performance, the Arc B370 is the choice based on the recorded data. Its higher core counts, faster clocks, lower power draw, and additional ray tracing hardware make it superior in every computed metric. The Arc Graphics 64EU Mobile remains a functional part for systems that were designed around the Meteor Lake platform, but it delivers roughly one-third of the FP32 performance of the newer part while consuming more power. The database records no scenario where the Arc Graphics 64EU Mobile outperforms the Arc B370.
