It is built on a 10 nm process at Intel's foundry. The Core Ultra 7 366H uses the Panther Lake architecture with the Panther Lake-H codename, belonging to the Ultra 7 generation. It is fabricated on a 3 nm process, also at Intel's foundry.

Core configuration differs significantly. The Core 3 100UL features 6 cores and 8 threads, while the Core Ultra 7 366H features 16 cores and 16 threads. This core count difference directly impacts multi-threaded performance, as the Ultra 7 has more than double the core count.

Cache hierarchies are also distinct. The Core 3 100UL has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 10 MB of shared L3 cache. The Core Ultra 7 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and a larger 18 MB of shared L3 cache. The larger per-core and shared caches on the Ultra 7 provide more on-die storage for frequently accessed data.

The integrated graphics differ as well. The Core 3 100UL includes UHD Graphics with 64 execution units. The Core Ultra 7 366H includes Intel Xe3 Graphics, which represents a newer generation of integrated graphics technology.

Specification Differences

The socket types are incompatible. The Core 3 100UL uses Intel Socket 1700, a desktop platform. The Core Ultra 7 366H uses Intel BGA 2540, a mobile soldered platform. This indicates that the two are not interchangeable in any system.

Clock speeds vary. The Core 3 100UL has a base clock of 1.20 GHz and a boost clock of 4.50 GHz. The Core Ultra 7 366H has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The Ultra 7 starts at a higher base frequency and reaches a higher boost frequency.

Thermal design power differs. The Core 3 100UL has a TDP of 15 watts. The Core Ultra 7 366H has a TDP of 25 watts. This means the Ultra 7 consumes more power and generates more heat, which is typical for a higher-performance part.

The Verdict

The data clearly shows that the Intel Core Ultra 7 366H is the superior processor in terms of raw performance. Its benchmark scores, core count, cache size, and architecture are all significantly more advanced than the Intel Core 3 100UL. The Ultra 7 366H sits in the 87th percentile of all CPUs, while the Core 3 100UL sits in the 50th percentile with no recorded benchmark scores. The Ultra 7's nearest rivals, such as the AMD Ryzen 9 5900X, are within a fraction of a percent in average score, confirming its high-end placement.

The Core 3 100UL, with its 15-watt TDP and desktop socket, is positioned for low-power desktop systems. Its lack of benchmark data in the database means its performance cannot be quantified here, but its specifications suggest a modest, energy-efficient part. The Ultra 7 366H, with a 25-watt TDP and mobile BGA socket, is designed for high-performance laptops and mobile workstations.

A user choosing between these parts would be selecting very different platforms. The Core 3 100UL targets basic desktop computing with low power draw. The Core Ultra 7 366H targets demanding mobile applications where performance is the priority. The recorded data offers no scenario where the Core 3 100UL outperforms the Core Ultra 7 366H.

Where Each One Wins

The Intel Core Ultra 7 366H wins in every measurable category according to the database. For multi-threaded tasks, its Cinebench R23 multicore score of 28477 and PassMark multithread score of 33429 are exceptionally high. For single-threaded tasks, its Cinebench R23 single-core score of 4020 and PassMark single-thread score of 4043 are also leading figures. Its memory bandwidth of 115.2 GB/s supports high-throughput workloads. The Ultra 7 is the clear choice for any application that demands maximum compute power, such as rendering, scientific simulations, or heavy multitasking.

The Intel Core 3 100UL has no recorded wins in the benchmark data. Its advantage lies in its lower power envelope, with a 15-watt TDP compared to the Ultra 7's 25 watts. This makes it suitable for fanless or passively cooled desktop systems where energy efficiency is the primary concern. Its support for DDR4 memory also provides a lower-cost platform for basic systems. However, based on the database, there is no performance scenario where the Core 3 100UL comes out ahead. The Ultra 7 366H is the definitive performance winner across all recorded tests.
