Intel Core Ultra 7 356H vs Intel Processor U301L Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive performance gap between the Intel Core Ultra 7 356H and the Intel Processor U301L. The Core Ultra 7 356H delivers overwhelming advantages across every measurable workload, while the U301L has no recorded benchmark scores in the database. This makes the comparison one-sided: the Core Ultra 7 356H holds all recorded wins, with the U301L producing zero scores for direct comparison.

Focusing on the Core Ultra 7 356H's recorded results, the data indicates strong multi-core capability. In Cinebench R23, the multicore score reaches 18395, while the single-core score is 2040. The R20 run shows 12153 multicore and 1715 single-core. The R15 run shows 3055 multicore and 303 single-core. These numbers place the Core Ultra 7 356H in the 87th percentile of all CPUs, with an average benchmark score of 41215.

The nearest rival data provides context for these scores. The Core Ultra 7 356H sits within 0.1% of the Intel Core Ultra 7 366H, which posts an average score of 41263. The AMD Ryzen AI 5 PRO 440 scores 41208, effectively tied at 0% delta. The AMD Ryzen 9 5900X scores 41376, putting the Core Ultra 7 356H 0.4% behind. The Intel Core Ultra X7 358H scores 40967, leaving the Core Ultra 7 356H 0.6% ahead. These deltas show the Core Ultra 7 356H performing in a tight cluster with high-end desktop and mobile parts from the previous generation.

PassMark results further detail the Core Ultra 7 356H's strengths. The multithread score is 33978, the single-thread score is 4072, and the integer math score is 83111. Floating point math reaches 103128, extended instructions score 27898, and data compression hits 336177. Data encryption scores 26345, find prime numbers scores 327, random string sorting scores 40990, and physics scores 2895.

Because the U301L has no benchmark entries, the head-to-head comparison cannot produce direct per-test deltas. The database records zero wins for the U301L and zero wins for the Core Ultra 7 356H in the headToHeadBenchmarks field, which reflects the absence of matched tests rather than a tie. The practical interpretation is clear: the Core Ultra 7 356H's recorded scores stand alone, and the U301L offers no measurable data to challenge them.

Where Each One Wins

The Core Ultra 7 356H wins in every category where data exists. Multi-core workloads favor it heavily: Cinebench R23 multicore at 18395, R20 multicore at 12153, and R15 multicore at 3055. The PassMark multithread score of 33978 and integer math score of 83111 reinforce this. The U301L has no recorded scores in any of these tests.

Single-core performance also goes to the Core Ultra 7 356H. Its Cinebench R23 single-core score is 2040, R20 single-core is 1715, and R15 single-core is 303. PassMark single-thread reaches 4072. The U301L offers no counter-data.

Specialized workloads show the same pattern. Data compression scores 336177 for the Core Ultra 7 356H, data encryption scores 26345, and extended instructions score 27898. Floating point math reaches 103128, random string sorting reaches 40990, and physics scores 2895. The find prime numbers score is 327. All of these favor the Core Ultra 7 356H by default, since the U301L has no entries.

The U301L's only advantages are structural rather than performance-based. Its 15 watt TDP is lower than the Core Ultra 7 356H's 25 watts, which may indicate lower power draw in constrained chassis. Its Intel Socket 1700 compatibility and DDR4 support could suit older platforms. Its launch MSRP of $107 provides a price reference, though the database does not record a launch MSRP for the Core Ultra 7 356H. These factors do not translate into benchmark wins, as the recorded data shows no U301L scores.
