The Verdict

The data shows a clear split between the two processors. The Intel Core 5 223PE dominates in measured performance, with a Cinebench R23 multi-core score of 26455 and a single-core score of 3734. Its 87th percentile ranking across all CPUs in the database confirms strong overall capability. The processor also delivers a Passmark multi-thread score of 31124 and a Passmark single-thread score of 4219. These are the only recorded benchmark numbers in this comparison.

The Intel Core Ultra 7 155HL has no benchmark scores in the database, so its performance cannot be measured or compared directly. However, its architecture provides clear advantages in specific areas. The 16-core, 22-thread configuration offers more parallelism than the 8-core, 16-thread Core 5 223PE. The Arc Xe-LPG 128EU integrated graphics is a more capable solution than the UHD Graphics 730. The lower TDP of 45 watts indicates a more power-efficient design than the 65-watt Core 5 223PE.

For users who need maximum processing throughput, the Core 5 223PE is the only choice with verified performance data. For users who prioritize integrated graphics quality, higher thread counts, or lower power consumption, the Core Ultra 7 155HL offers those features on paper. The choice depends on whether verified benchmark performance or specific architectural features matter more.
