Architecture Differences

The two processors stem from entirely different Intel architectures. The Core i3-14100 is built on Raptor Lake, specifically the Raptor Lake-R refresh, using a 10 nm process node. It features 4 cores and 8 threads, with a base clock of 3.50 GHz and a boost clock of 4.70 GHz. Its cache layout includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The chip is a desktop part, socketed into Intel Socket 1700, with a TDP of 60.

The Core Ultra 9 386H represents the Panther Lake architecture, built on a 3 nm process. It has 16 cores and 16 threads, with a lower base clock of 2.10 GHz but a higher boost clock of 4.90 GHz. Its cache configuration is more generous: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. This is a mobile processor, using Intel BGA 2540, with a TDP of 25. It supports DDR5 and LPDDR5X memory, listing a memory bandwidth of 115.2 GB/s, whereas the i3-14100 supports DDR4 and DDR5 with no recorded bandwidth figure.

The integrated graphics also differ. The i3-14100 uses UHD Graphics 730, while the Ultra 9 386H uses Intel Xe3 Graphics. PCIe lanes differ as well: the desktop chip offers Gen 5 with 16 lanes (CPU only), and the mobile chip offers Gen 5 with 12 lanes (CPU only). The Ultra 9 also has a larger L1 and L2 per-core allocation, reflecting its newer design. Notably, the i3-14100 supports ECC memory, a feature absent on the Ultra 9.

The Verdict

The recorded data points to a clear hierarchy. The Core Ultra 9 386H outscores the Core i3-14100 in every single benchmark in the database, from Cinebench R15 multicore to PassMark integer math. It wins 17 of 17 head-to-head comparisons, with deltas ranging from 10.9% (PassMark single-thread) to 83.9% (PassMark find prime numbers). Its average benchmark score of 43210 is more than double the i3-14100’s 18318, and it sits in the 88th percentile versus the 72nd percentile.

For users prioritizing raw performance, especially in multi-threaded workloads, the Core Ultra 9 386H is the only choice from this pair. Its 16 cores and higher boost clock produce massive leads in Cinebench R20 multicore (12820 versus 5384) and PassMark multithread (35399 versus 15095). The i3-14100, however, is a desktop part with a socketed form factor, a 60 TDP, and ECC memory support. The data does not show any benchmark where the i3-14100 wins, so its appeal rests on its desktop platform, lower power envelope at 25 TDP for the Ultra 9 versus 60 for the i3, and its $134 launch MSRP.

The Core Ultra 9 386H is the stronger processor in every measured metric. The i3-14100 remains relevant only for desktop builds that require its specific socket, ECC support, or DDR4 compatibility. The Ultra 9’s nearest rivals in the database include the AMD Ryzen AI Max PRO 385 (0.3% higher average score) and the Intel Core i9-12900 (0.7% lower), placing it in high-end territory. The i3-14100’s nearest rivals are all within 0.3% of its score, including the Core i3-13100.

Head-to-Head Benchmarks

The Core Ultra 9 386H dominates every recorded comparison, but the margins vary by workload. The smallest gap appears in single-thread tests. In Cinebench R23 single-core, the Ultra 9 scores 2071.5 against 1809 for the i3-14100, a 12.7% lead. PassMark single-thread shows a similar pattern: 4218 versus 3759, a 10.9% delta. These results indicate the Ultra 9’s higher 4.90 GHz boost clock provides a meaningful single-core edge, but the gap is far smaller than in multi-threaded tests.

Multi-threaded performance is where the Ultra 9 pulls away decisively. In Cinebench R15 multicore, it scores 3223 versus 1292, a 59.9% difference. Cinebench R20 multicore shows 12820 versus 5384, a 58% gap. Cinebench R23 multicore narrows that somewhat: 20547 versus 12820, a 37.6% difference. The PassMark multithread test records 35399 for the Ultra 9 against 15095 for the i3-14100, a 57.4% margin.

The largest single delta appears in PassMark find prime numbers, where the Ultra 9 scores 341 versus 55, an 83.9% advantage. This test heavily favors the extra cores and threads. Similarly, PassMark floating point math shows 108527 versus 35266, a 67.5% gap, and PassMark physics records 3028 versus 958, a 68.4% difference. Integer math is less lopsided but still substantial: 87284 versus 45329, a 48.1% lead.

Specialized workloads follow the same trend. PassMark data encryption shows 27150 versus 8838, a 67.4% delta. Extended instructions score 29138 versus 11865, a 59.3% margin. Random string sorting records 42135 versus 17397, a 58.7% gap. Data compression is also one-sided: 352365 versus 174115, a 50.6% difference.

The Core Ultra 9 386H wins all 17 head-to-head benchmarks in the database, with no recorded wins for the Core i3-14100. The average benchmark scores confirm the hierarchy: 43210 for the Ultra 9, 18318 for the i3-14100, placing them in the 88th and 72nd percentiles of all CPUs respectively. The data shows the Ultra 9 as the unequivocally faster processor, with its smallest advantages in single-thread tests and its largest in multi-threaded and math-heavy workloads.
