Where Each One Wins

The Intel Core Ultra 5 225H is the clear winner across all recorded benchmark categories. The database contains 19 benchmark scores for the Ultra 5 225H, and it wins 19 out of 19 head-to-head comparisons. The Arc G3 has no recorded benchmark scores in the database, which means there is no measured data showing where it outperforms the Ultra 5 225H.

For compute-heavy workloads, the Ultra 5 225H shows substantial strength. Its Cinebench R23 multicore score of 14629.5 points and Geekbench multicore score of 11526 points indicate a processor well-suited for rendering and multi-threaded tasks. The PassMark multithread score of 28119 reinforces this pattern.

Single-threaded performance is also strong on the Ultra 5 225H. Its PassMark single-thread score of 4258 and Cinebench R23 single-core score of 1969 demonstrate capable everyday responsiveness. The Geekbench single-core score of 2151 adds further evidence.

Specialized workloads favor the Ultra 5 225H as well. The PassMark data compression score of 283451 and data encryption score of 21428 show strong throughput for archiving and security-related tasks. The extended instructions score of 21915 and floating point math score of 86540 indicate solid performance in scientific and mathematical calculations.

The Arc G3, lacking any recorded benchmarks, has no measured wins in the database. Its higher base clock of 1.90 GHz versus 1.70 GHz on the Ultra 5 225H suggests potential, but without benchmark data, no analytical conclusion can be drawn about its real-world performance.

Architecture Differences

The two processors come from different Intel generations and use different foundries for manufacturing. The Intel Arc G3 is part of the Panther Lake generation and carries the generation label "Arc G3 (Panther Lake)". The Intel Core Ultra 5 225H belongs to the Core Ultra Series 2, with the codename Arrow Lake-H and generation label "Ultra 5 (Arrow Lake-H)".

Both chips are fabricated on a 3 nm process node, but the foundry differs. The Arc G3 is manufactured by Intel itself, while the Ultra 5 225H is manufactured by TSMC. This is a significant architectural distinction, as the two chips come from different production facilities despite using the same process size.

Cache hierarchies show both similarities and differences. Both processors share 192 KB of L1 cache per core and 18 MB of shared L3 cache. The L2 cache differs: the Arc G3 has 2.5 MB per core, while the Ultra 5 225H has 3 MB per core. This gives the Ultra 5 225H a 0.5 MB per core advantage in L2 cache.

The memory controllers differ in bandwidth capability. The Arc G3 supports LPDDR5X with a measured memory bandwidth of 136.5 GB/s. The Ultra 5 225H supports both DDR5 and LPDDR5X but has a lower measured memory bandwidth of 102.4 GB/s. The Arc G3 holds a 34.1 GB/s advantage in this metric.

PCIe connectivity also differs. The Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Ultra 5 225H provides Gen 5 with 8 lanes (CPU only). The Ultra 5 225H doubles the available CPU PCIe lanes.

Integrated graphics differ between the two. The Arc G3 uses an Arc B370 iGPU, while the Ultra 5 225H uses an Arc Graphics 130T iGPU. No benchmark data is recorded for either iGPU.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries between these two processors. However, the Intel Core Ultra 5 225H has 19 individual benchmark scores, while the Intel Arc G3 has none. This means the Ultra 5 225H wins every measurable comparison by default.

Starting with multi-threaded performance, the Ultra 5 225H scores 2397.5 in Cinebench R15 multicore, 10041 in Cinebench R20 multicore, and 14629.5 in Cinebench R23 multicore. The Geekbench multicore score is 11526. In PassMark tests, the multithread score is 28119, integer math scores 68520, floating point math scores 86540, and extended instructions score 21915.

Single-threaded results are equally decisive. The Ultra 5 225H scores 288.5 in Cinebench R15 single-core, 1417 in Cinebench R20 single-core, and 1969 in Cinebench R23 single-core. The Geekbench single-core score is 2151, and PassMark single-thread scores are 4258.

Data handling workloads show strong results. PassMark data compression scores 283451, data encryption scores 21428, and random string sorting scores 33654. The find prime numbers test scores 220, while the physics test scores 1877.

The percentile ranking confirms the Ultra 5 225H's position. It sits at the 82nd percentile among all CPUs in the database, with an average benchmark score of 31508.

The Arc G3 holds a 50th percentile ranking with an average benchmark score of 0, reflecting the complete absence of recorded benchmark data. It has no nearest rivals listed in the database.

The Verdict

The Intel Core Ultra 5 225H is the only one of these two processors with measured performance data. Its 82nd percentile ranking places it well above the Arc G3's 50th percentile ranking, and its average benchmark score of 31508 stands against the Arc G3's score of 0.

For multi-threaded workloads such as rendering, video encoding, or scientific computation, the Ultra 5 225H delivers verified results. The Cinebench R23 multicore score of 14629.5 and PassMark multithread score of 28119 indicate a capable mobile processor. The 14 cores and 14 threads provide ample parallelism for most productivity applications.

For single-threaded tasks, the Ultra 5 225H also holds the advantage. Its 4.90 GHz boost clock is 0.30 GHz higher than the Arc G3's 4.60 GHz, and its benchmark scores confirm strong single-core performance. The PassMark single-thread score of 4258 and Geekbench single-core score of 2151 demonstrate this capability.

The Arc G3 does hold advantages in specific specifications. Its base clock is 0.20 GHz higher at 1.90 GHz. Its memory bandwidth is 34.1 GB/s higher at 136.5 GB/s. Its TDP is 3 watts lower at 25 watts. However, without any benchmark scores, these advantages cannot be validated in real-world performance.

The release dates favor the Ultra 5 225H in terms of market maturity. It released on 2025-01-12, over a year before the Arc G3's 2026-05-27 release. The Ultra 5 225H has had more time for software optimization and driver maturation.

The socket difference means these are not interchangeable parts. The Arc G3 uses Intel BGA 2540, while the Ultra 5 225H uses Intel BGA 2049. System designers must choose based on platform compatibility.

For anyone selecting between these two, the database provides a clear answer. The Intel Core Ultra 5 225H has extensive benchmark evidence showing strong performance across every measured category. The Intel Arc G3 has no measured evidence of performance capability. The data supports the Ultra 5 225H for any workload where verified performance matters. The Arc G3 remains an unproven quantity in this comparison.
