Intel Core Ultra 7 366H vs Intel Processor U302L Comparison

Intel Core Ultra 7 366H vs Intel Processor U302L

The Intel Core Ultra 7 366H is a 16-core, 16-thread mobile processor built on Intel's 3 nm Panther Lake architecture, while the Intel Processor U302L is a 5-core, 6-thread part on the older 10 nm Raptor Lake-PS design. The benchmark database shows a decisive performance gap between the two, with the Ultra 7 366H scoring in the 87th percentile of all CPUs tested, while the U302L sits at the 50th percentile. The U302L has no recorded benchmark scores in the database, so all comparative analysis relies on the Ultra 7 366H's measured results and architectural specifications.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two processors, as the Intel Processor U302L has an empty benchmark record. However, the Intel Core Ultra 7 366H has a comprehensive set of 17 recorded benchmark scores that establish its performance ceiling. The U302L's lack of recorded scores means no direct numerical comparison can be drawn from the data, but the architectural disparity is stark.

The Ultra 7 366H delivers strong multi-threaded performance in Cinebench tests. It scores 28,477 in Cinebench R23 multi-core, 11,960 in Cinebench R20 multi-core, and 2,870 in Cinebench R15 multi-core. Single-core results are equally notable: 4,020 in Cinebench R23, 1,688 in Cinebench R20, and 405 in Cinebench R15. These figures place the chip well above the median CPU in the database, reflected in its 87th percentile ranking.

PassMark results further illustrate the Ultra 7 366H's capabilities. The multi-thread test shows 33,429, with integer math at 83,695, floating point math at 103,615, and extended instructions at 26,901. Data compression reaches 327,455, data encryption scores 25,845, and random string sorting hits 39,814. The single-thread PassMark score is 4,043, while the physics test records 2,880 and find prime numbers scores 326. These numbers indicate a processor that handles both integer-heavy and floating-point workloads with considerable headroom.

The average benchmark score for the Ultra 7 366H is 41,263. Its nearest rivals in the database show how tightly grouped this performance tier is. The Intel Core Ultra 7 356H averages 41,215, a delta of 0.1%. The AMD Ryzen AI 5 PRO 440 also averages 41,208, another 0.1% delta. The AMD Ryzen 9 5900X averages 41,376, which is 0.3% ahead of the Ultra 7 366H, while the Intel Core Ultra X7 358H averages 40,967, putting it 0.7% behind. These deltas are small, indicating that the Ultra 7 366H sits in a tightly contested performance band among modern mobile and desktop parts.

Where Each One Wins

The Intel Core Ultra 7 366H wins in every measurable benchmark category present in the database, simply because it has recorded scores while the Intel Processor U302L does not. The data shows the Ultra 7 366H is designed for demanding workloads: its 16 cores and 16 threads, paired with a 4.80 GHz boost clock, make it suitable for multi-threaded rendering, video encoding, and heavy productivity tasks. The Cinebench R23 multi-core score of 28,477 indicates strong sustained performance under load, while the PassMark integer and floating point math scores of 83,695 and 103,615 respectively show balanced compute capability.

The U302L, with 5 cores and 6 threads, a 2.40 GHz boost clock, and a 15 W TDP, is positioned for lower-power, lighter-duty scenarios. Its architecture supports DDR4 and DDR5 memory, giving it flexibility in system design, but its performance ceiling is far lower. The data does not record any benchmark wins for the U302L, so any advantage it holds would be in power efficiency and thermal footprint rather than raw compute. The 15 W TDP compared to the Ultra 7 366H's 25 W TDP suggests the U302L fits into thinner, fanless or lightly cooled chassis where battery life and quiet operation matter more than throughput.

The Ultra 7 366H's 87th percentile ranking versus the U302L's 50th percentile makes the use-case split clear. The Ultra 7 366H targets users running heavy software: 3D modeling, video editing, software compilation, or scientific computation. The U302L targets basic productivity, web browsing, office applications, and light media consumption where its lower core count and clock speeds are sufficient and its lower power draw is an advantage.

Architecture Differences

The two processors come from different Intel design generations and manufacturing nodes. The Intel Core Ultra 7 366H uses the Panther Lake architecture on a 3 nm process node, fabricated by Intel. It belongs to the Core Ultra Series 3 and is part of the Ultra 7 (Panther Lake-H) generation. The Intel Processor U302L uses the Raptor Lake architecture on a 10 nm process node, also fabricated by Intel, under the Intel Processor (Raptor Lake) generation label.

Core and thread counts differ substantially. The Ultra 7 366H has 16 cores and 16 threads, while the U302L has 5 cores and 6 threads. This means the U302L has hyper-threading on some cores, giving it 6 threads from 5 cores, while the Ultra 7 366H has equal core and thread counts. Clock speeds reflect their positioning: the Ultra 7 366H has a 2.00 GHz base clock and 4.80 GHz boost clock, while the U302L has a 1.20 GHz base clock and 2.40 GHz boost clock. The U302L's boost clock is half the Ultra 7 366H's.

Cache hierarchies are also different. The Ultra 7 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The U302L has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. The Ultra 7 366H's larger per-core caches and nearly double the L3 capacity give it a significant advantage in workloads that benefit from data locality.

Memory support diverges as well. The Ultra 7 366H supports DDR5 and LPDDR5X memory in a dual-channel configuration with a recorded memory bandwidth of 115.2 GB/s. The U302L supports DDR4 and DDR5 in dual-channel, but its memory bandwidth is not recorded in the database. The Ultra 7 366H uses PCIe Gen 5 with 12 lanes (CPU only), while the U302L uses PCIe Gen 4 with 8 lanes (CPU only). Integrated graphics differ: the Ultra 7 366H has Intel Xe3 Graphics, while the U302L has UHD Graphics 80EU.

The sockets are incompatible. The Ultra 7 366H uses Intel BGA 2540, while the U302L uses Intel Socket 1700. Neither processor has an unlocked multiplier. The Ultra 7 366H was released in 2026, while the U302L came out in 2024. The U302L has a recorded launch MSRP of $285; the Ultra 7 366H has no recorded launch MSRP.

The Verdict

The data overwhelmingly favors the Intel Core Ultra 7 366H for any performance-oriented use case. Its 16 cores, 4.80 GHz boost clock, 18 MB of L3 cache, and 115.2 GB/s memory bandwidth place it in the 87th percentile of all CPUs in the database. The recorded Cinebench and PassMark scores confirm strong multi-threaded and single-threaded capability. The nearest rivals in the database, including the AMD Ryzen 9 5900X, show deltas of less than 1%, meaning the Ultra 7 366H competes with established high-end desktop parts despite being a mobile chip.

The Intel Processor U302L is a fundamentally different product. With 5 cores, a 2.40 GHz boost clock, 10 MB of L3 cache, and no recorded benchmark scores, it occupies the 50th percentile. Its 15 W TDP and support for DDR4 and DDR5 make it suitable for low-power systems where the 25 W TDP of the Ultra 7 366H might be excessive. The U302L also has a recorded launch MSRP of $285, though pricing considerations are not part of this analysis.

Users who need sustained multi-threaded performance for rendering, compilation, or content creation should choose the Ultra 7 366H. The data shows it delivers scores that rival the AMD Ryzen 9 5900X, a desktop processor from a higher power class. Users who prioritize minimal power draw, low heat output, and basic productivity in a compact chassis should consider the U302L, but they must accept that it has no recorded performance data to validate its capabilities. The benchmark database clearly indicates that the Ultra 7 366H is the superior processor in every measurable way.
