Architecture Differences

The Intel Core Ultra 7 366H and Intel Processor U301L belong to different architectural generations entirely. The 366H is part of the Core Ultra Series 3, built on the Panther Lake architecture with a codename of Panther Lake. It represents the Ultra 7 tier within the Panther Lake-H generation. The U301L uses the older Raptor Lake architecture, specifically the Raptor Lake-PS codename, and belongs to the Intel Processor (Raptor Lake) generation.

The manufacturing process separates them clearly. The 366H uses a 3 nm process node, while the U301L uses a 10 nm node. Both are fabricated by Intel, but the node difference indicates a significant generational gap in density and efficiency potential.

Cache hierarchies differ substantially. The 366H provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The U301L provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The 366H has more than double the L3 capacity and double the per-core L2.

The integrated graphics differ as well. The 366H carries Intel Xe3 Graphics, while the U301L uses UHD Graphics 64EU. Memory support differs: the 366H supports DDR5 and LPDDR5X, while the U301L supports DDR4 and DDR5. The 366H has a memory bandwidth rating of 115.2 GB/s, while the U301L has no recorded bandwidth figure in the database. Both use dual-channel memory buses.

PCIe connectivity differs between the two. The 366H supports PCIe Gen 5 with 12 lanes (CPU only). The U301L supports PCIe Gen 4 with 8 lanes (CPU only). The 366H uses an Intel BGA 2540 socket, while the U301L uses Intel Socket 1700. Neither processor has an unlocked multiplier, and neither supports ECC memory.

Head-to-Head Benchmarks

The head-to-head benchmark array for these two processors is empty. The Intel Processor U301L has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and it has no nearest rivals recorded. The Intel Core Ultra 7 366H, by contrast, has a full suite of benchmark results across Cinebench and PassMark tests.

The 366H's recorded data shows strong multi-threaded performance. In Cinebench R23 multicore, it scores 28477. In Cinebench R20 multicore, it scores 11960. In Cinebench R15 multicore, it scores 2870. Single-core results are also robust: Cinebench R23 singlecore scores 4020, Cinebench R20 singlecore scores 1688, and Cinebench R15 singlecore scores 405.

PassMark results for the 366H cover several workloads. Multithread scores 33429, single thread scores 4043 (recorded twice in the database under slightly different test names), data compression scores 327455, data encryption scores 25845, extended instructions scores 26901, find prime numbers scores 326, floating point math scores 103615, integer math scores 83695, physics scores 2880, and random string sorting scores 39814.

The average benchmark score for the 366H is 41263. Its percentile rank among all CPUs is 87. The nearest rivals in the database are the Intel Core Ultra 7 356H with an average score of 41215 (0.1% difference), the AMD Ryzen AI 5 PRO 440 with an average score of 41208 (0.1% difference), the AMD Ryzen 9 5900X with an average score of 41376 (-0.3% difference), and the Intel Core Ultra X7 358H with an average score of 40967 (0.7% difference). These deltas show the 366H sits in a tight performance cluster, within roughly a percentage point of its closest competitors.

Because the U301L has no benchmark entries, the comparison is one-sided. The data confirms the 366H delivers substantial computational output, while the U301L has no recorded measurements against which to compare directly.

Where Each One Wins

The Intel Core Ultra 7 366H wins across all measurable computational categories because it is the only one of the two with recorded benchmark data. Its 16 cores and 16 threads provide a base for multi-threaded workloads that the 5-core, 6-thread U301L cannot match. The 4.80 GHz boost clock versus 2.20 GHz gives the 366H a clear advantage in single-threaded responsiveness as well.

For sustained workloads such as rendering, data compression, encryption, and floating-point math, the 366H's benchmark scores show strong output. The Cinebench R23 multicore score of 28477 and PassMark multithread score of 33429 indicate the processor handles parallel tasks effectively. The PassMark data compression score of 327455 and integer math score of 83695 reinforce this pattern.

The U301L has no benchmark scores, so the database contains no evidence of any workload category where it outperforms the 366H. Its lower TDP of 15 versus 25 suggests a more power-conscious design, but the database does not record any efficiency measurements. Its support for DDR4 memory could be relevant for systems using older memory modules, but no performance data supports a specific advantage.

The 366H also wins on platform capabilities. PCIe Gen 5 with 12 lanes exceeds the U301L's PCIe Gen 4 with 8 lanes. The 3 nm process node versus 10 nm indicates a newer manufacturing technology. The larger L3 cache of 18 MB versus 8 MB provides more on-chip storage for frequently accessed data.

The Verdict

The recorded data shows a decisive performance gap between these two processors. The Intel Core Ultra 7 366H delivers comprehensive benchmark results with an average score of 41263 and a percentile rank of 87. The Intel Processor U301L has no benchmark entries and an average score of 0, placing it at the 50th percentile.

The 366H targets demanding mobile workloads. Its 16 cores, 16 threads, 4.80 GHz boost clock, and 115.2 GB/s memory bandwidth support compute-heavy applications. Its near-rival cluster includes the AMD Ryzen 9 5900X, a desktop-class processor, and the 366H trails it by only 0.3% in average score. This places the 366H in strong company for a mobile chip.

The U301L targets more modest requirements. Its 5 cores, 6 threads, 2.20 GHz boost clock, and 8 MB L3 cache suit lighter tasks. Its support for DDR4 memory and lower TDP of 15 indicate a design focused on simplicity and power economy rather than peak throughput.

The database offers no benchmark evidence that the U301L can compete with the 366H in any measured workload. The 366H leads in core count, clock speed, cache size, process node, memory bandwidth, PCIe generation, and integrated graphics tier. The U301L has a launch MSRP of $107, while the 366H has no recorded launch MSRP.

For users prioritizing computation speed, multitasking, or media creation, the 366H is the clear choice based on the data. For users with minimal processing demands who prioritize lower power consumption and a lower launch price, the U301L presents a simpler option, but the database does not quantify its performance advantages. The measured results, where they exist, belong entirely to the 366H.
