Intel Core Ultra 7 356H vs Intel Processor U302L Comparison

Head-to-Head Benchmarks

The benchmark database contains no direct head-to-head test results for the Intel Core Ultra 7 356H and the Intel Processor U302L. The head-to-head benchmark array is empty, and neither processor records a win in shared tests. This absence of comparative data is itself informative, as it reflects the vastly different market positions and testing histories of these two mobile processors.

The Intel Core Ultra 7 356H has a comprehensive benchmark record across Cinebench and PassMark suites, while the Intel Processor U302L has no recorded benchmark scores in the database. The Core Ultra 7 356H achieves an average benchmark score of 41215 across all recorded tests, placing it in the 87th percentile of all CPUs tracked. The U302L sits in the 50th percentile with an average benchmark score of 0, indicating that no performance measurements have been logged for it.

Without direct head-to-head results, the nearest rivals of the Core Ultra 7 356H provide context for its performance tier. The AMD Ryzen AI 5 PRO 440 scores 41208, a 0% delta from the Core Ultra 7 356H. The Intel Core Ultra 7 366H scores 41263, which is 0.1% higher. The AMD Ryzen 9 5900X scores 41376, 0.4% higher. The Intel Core Ultra X7 358H scores 40967, which is 0.6% lower. These four rivals cluster tightly around the Core Ultra 7 356H, indicating that its performance level is well-established within a narrow competitive band.

The absence of U302L benchmark data means no exact numerical comparison can be drawn between the two processors. The Core Ultra 7 356H demonstrates strong single-thread and multi-thread capabilities in its recorded tests. In Cinebench R23, it scores 18395 in multi-core and 2040 in single-core. Cinebench R20 results show 12153 multi-core and 1715 single-core. Cinebench R15 shows 3055 multi-core and 303 single-core. PassMark integer math scores 83111, floating point math scores 103128, and multithread scores 33978. These figures position the Core Ultra 7 356H as a capable performer in its class, consistent with its 87th percentile ranking.

Where Each One Wins

The Intel Core Ultra 7 356H wins in every measurable performance category for which data exists. Its 16 cores and 16 threads provide substantial parallel processing capacity, reflected in the multi-core Cinebench scores. The 18 MB shared L3 cache supports data-intensive workloads, and the PassMark data compression score of 336177 indicates strong throughput in compression tasks. Data encryption scores 26345, extended instructions score 27898, and random string sorting scores 40990. Physics calculations score 2895, and prime number finding scores 327. Single-thread performance is recorded at 4072 in PassMark, confirming that the architecture delivers strong per-core efficiency alongside its multi-thread capability.

The Intel Processor U302L has no recorded wins because it has no recorded benchmark scores. Its 5 cores and 6 threads represent a fundamentally smaller compute configuration. The 10 MB shared L3 cache is smaller than the Core Ultra 7 356H's 18 MB. The U302L's base clock of 1.20 GHz and boost clock of 2.40 GHz are lower than the Core Ultra 7 356H's 1.90 GHz base and 4.70 GHz boost. These specifications suggest the U302L is positioned for lower-power, lighter-duty mobile workloads, but the database contains no performance measurements to confirm or quantify its capabilities.

For users analyzing the data, the Core Ultra 7 356H is the only processor in this comparison with verified performance results. The U302L's lack of recorded scores means any assessment of its real-world performance must remain qualitative, based solely on its architectural specifications.

Architecture Differences

The Intel Core Ultra 7 356H uses the Panther Lake architecture, built on a 3 nm process node at Intel's foundry. It belongs to the Core Ultra Series 3 generation, specifically the Ultra 7 Panther Lake-H family. The processor uses the Intel BGA 2540 socket and operates at a TDP of 25 watts. Its cache hierarchy includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache.

The Intel Processor U302L uses the Raptor Lake architecture, built on a 10 nm process node. It belongs to the Raptor Lake-PS generation and uses the Intel Socket 1700. Its TDP is 15 watts, 10 watts lower than the Core Ultra 7 356H. The cache layout is smaller: 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache.

The core configurations differ substantially. The Core Ultra 7 356H has 16 cores and 16 threads, while the U302L has 5 cores and 6 threads. The Core Ultra 7 356H's clock speeds reach 4.70 GHz boost, compared to the U302L's 2.40 GHz boost.

The Verdict

The recorded data clearly favors the Intel Core Ultra 7 356H across every dimension where information exists. Its 87th percentile ranking, 41215 average benchmark score, and comprehensive test results confirm a high-performance mobile processor. The 16-core, 16-thread configuration with 4.70 GHz boost and 18 MB L3 cache delivers strong multi-threaded and single-threaded performance, as shown in Cinebench R23 scores of 18395 multi-core and 2040 single-core.

The Intel Processor U302L presents a different profile entirely. With 5 cores, 6 threads, a 2.40 GHz boost clock, 10 MB L3 cache, and a 15 watt TDP, it targets lower-power mobile applications. The absence of benchmark scores in the database means its actual performance cannot be verified against the Core Ultra 7 356H or any other processor.

Architecturally, the Core Ultra 7 356H is two generations ahead, using Panther Lake on 3 nm versus Raptor Lake on 10 nm. It supports PCIe Gen 5 with 12 lanes versus Gen 4 with 8 lanes. It offers faster memory with 115.2 GB/s bandwidth. Its integrated graphics use Intel Xe3, a newer architecture than the U302L's UHD Graphics 80EU.

The U302L's launch MSRP is $285, stated once here for reference. The Core Ultra 7 356H has no recorded launch MSRP in the database.

For workloads requiring substantial compute, the Core Ultra 7 356H is the only processor in this comparison with measured performance data, and that data shows strong results in the 87th percentile of all CPUs. The U302L, based on its specifications, appears oriented toward efficiency and basic mobile tasks, but the database cannot confirm its performance level.
