The Verdict

The benchmark database shows a decisive performance gap between these two processors. The Intel Core Ultra 7 366H wins all 17 recorded head-to-head comparisons, with no benchmark victories for the Intel Core 3 100HL. The Core Ultra 7 366H sits in the 87th percentile of all CPUs, while the Core 3 100HL sits in the 76th percentile. The average benchmark score for the Core Ultra 7 366H is 41263, versus 23545 for the Core 3 100HL.

The Core 3 100HL fits a specific niche. It is a desktop processor on Intel Socket 1700 with 8 cores and 12 threads, using Raptor Lake architecture. Its nearest rivals include the AMD Ryzen 5 PRO 8540U (0.7% behind), the Intel Core i5-11500 (0.7% behind), the Intel Core Ultra 7 266V (1.1% ahead), and the AMD Ryzen 7 5800H (1.2% ahead). This places the Core 3 100HL in the same performance class as those parts, making it suitable for mainstream desktop builds where raw multi-threaded throughput is not the primary demand.

The Core Ultra 7 366H is a mobile processor on Intel BGA 2540 with 16 cores and 16 threads, using Panther Lake architecture. Its nearest rivals are the Intel Core Ultra 7 356H (0.1% ahead), the AMD Ryzen AI 5 PRO 440 (0.1% ahead), the AMD Ryzen 9 5900X (0.3% behind), and the Intel Core Ultra X7 358H (0.7% ahead). The data indicates this chip performs at the level of a high-end desktop processor from a previous generation, despite being a 25W mobile part.

Users who need a desktop upgrade on the LGA 1700 platform with modest multi-core demands should consider the Core 3 100HL. Users who prioritize portable performance, especially in rendering or encryption workloads, should choose the Core Ultra 7 366H. The data does not support any scenario where the Core 3 100HL outperforms the Core Ultra 7 366H in the recorded tests.

Architecture Differences

The two processors differ fundamentally in design generation and target platform. The Core 3 100HL uses Raptor Lake architecture with the Raptor Lake-PS codename, built on a 10 nm process node. The Core Ultra 7 366H uses Panther Lake architecture with the Panther Lake-H codename, built on a 3 nm process node. Both are manufactured by Intel, but the process node difference represents a substantial generational shift in transistor density and power efficiency.

Core configuration differs significantly. The Core 3 100HL has 8 cores and 12 threads, indicating a hybrid layout with performance and efficiency cores. The Core Ultra 7 366H has 16 cores and 16 threads, meaning every core has a dedicated thread without hyper-threading. This is a notable architectural choice: the newer chip doubles the core count but keeps thread count equal to core count, while the older chip uses fewer physical cores with additional threads.

Cache hierarchies diverge as well. The Core 3 100HL has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 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 18 MB of shared L3 cache. The newer part provides larger per-core caches at every level, which benefits workloads with high data reuse.

Memory support differs. The Core 3 100HL supports DDR4 and DDR5 in a dual-channel configuration. The Core Ultra 7 366H supports DDR5 and LPDDR5X, also dual-channel, with a recorded memory bandwidth of 115.2 GB/s. The Core 3 100HL has no recorded memory bandwidth figure. PCIe connectivity also differs: the Core 3 100HL provides Gen 4 with 8 lanes (CPU only), while the Core Ultra 7 366H provides Gen 5 with 12 lanes (CPU only).

Integrated graphics differ. The Core 3 100HL uses Iris Xe Graphics with 48 execution units. The Core Ultra 7 366H uses Intel Xe3 Graphics. The newer graphics architecture is expected to deliver better iGPU performance, though no iGPU benchmarks are recorded in this database.

Base and boost clocks differ slightly. The Core 3 100HL runs at 2.10 GHz base and 4.60 GHz boost. The Core Ultra 7 366H runs at 2.00 GHz base and 4.80 GHz boost. Despite a lower base clock, the newer chip achieves a higher boost frequency. The TDP figures differ substantially: the Core 3 100HL is rated at 45W, while the Core Ultra 7 366H is rated at 25W. This means the Core Ultra 7 366H delivers far higher performance while consuming less power, per the recorded specifications.

The Core 3 100HL targets the desktop market segment and was released in April 2024. The Core Ultra 7 366H targets the mobile segment and was released in January 2026. Both parts are listed as Active in production status. Neither has a recorded launch MSRP. Neither has an unlocked multiplier.

Where Each One Wins

The Core Ultra 7 366H wins all 17 recorded benchmark comparisons, so the use-case split is clear from the data. The Core 3 100HL has no recorded wins. However, the magnitude of the differences varies by workload, which suggests where each chip is relatively stronger.

The Core Ultra 7 366H shows its largest advantages in prime number calculation (85.3% delta), physics simulation (67.8% delta), and floating-point math (59.4% delta). These workloads benefit most from the 16-core configuration and the newer Panther Lake architecture. For users running physics simulations, mathematical modeling, or other floating-point-heavy tasks, the Core Ultra 7 366H is the clear choice.

The Core Ultra 7 366H shows its smallest advantage in single-threaded integer work. PassMark single-thread shows only a 7.6% delta. This means the Core 3 100HL is relatively closer in everyday single-threaded responsiveness, despite the newer chip still winning. The Core 3 100HL also shows a relatively smaller gap in integer math (32.7%) and data compression (38.2%), which are less dependent on raw core count.

The Core 3 100HL remains viable for desktop builds where the user already owns an LGA 1700 motherboard and does not require extreme multi-threaded performance. Its 45W TDP and DDR4 support allow for simpler, lower-cost system configurations. The Core Ultra 7 366H requires a BGA 2540 mobile platform and DDR5 or LPDDR5X memory, which is typical for laptops and compact mobile systems.

For mobile users, the Core Ultra 7 366H provides desktop-class rendering performance in a 25W package. The data confirms that the newer chip is not just faster but also more efficient per watt, given that it more than doubles multi-threaded scores while consuming nearly half the TDP. For users who need portable computing with heavy processing demands, the Core Ultra 7 366H is the only choice between these two parts.
