Intel Core i3-14100 vs Intel Core i5-13420H Comparison

The Intel Core i5-13420H and Intel Core i3-14100 represent two distinct interpretations of the Raptor Lake architecture, one optimized for mobile efficiency and the other for desktop responsiveness. The benchmark data reveals a clear split: the i5-13420H dominates in multi-threaded and data-heavy workloads, while the i3-14100 counters with superior single-core performance in select tests. Both processors land at the 72nd percentile against all CPUs, yet they achieve this parity through fundamentally different core configurations and power envelopes.

Head-to-Head Benchmarks

The most decisive victory for the Intel Core i5-13420H comes in Cinebench R15 multicore, where it scores 1738 against the i3-14100's 1292, a 34.5% advantage. This gap narrows considerably in Cinebench R20 multicore, with the i5-13420H leading 6013 to 5384 (11.7%), but the pattern reverses in Cinebench R23 multicore. Here, the i3-14100 takes a surprising 13.5% lead, scoring 12820 versus 11084. This inversion across Cinebench versions suggests the i3-14100's higher boost clock of 4.70 GHz sustains performance better in longer, more demanding rendering workloads, while the i5-13420H's 8 cores and 12 threads dominate shorter multi-threaded bursts.

Single-core results are similarly split. The i5-13420H wins Cinebench R15 singlecore by 30.8% (238 vs 182) and Cinebench R20 singlecore by 11.7% (848 vs 759), yet the i3-14100 takes Cinebench R23 singlecore by 6.6% (1809 vs 1689) and PassMark single-thread by 9.7% (3759 vs 3396). The i3-14100's 4.70 GHz boost clock clearly gives it an edge in PassMark's single-threaded integer testing, while the i5-13420H's architecture seems better suited to the older Cinebench single-core tests.

In PassMark's comprehensive suite, the i5-13420H wins 12 of 17 head-to-head comparisons. The largest margins come in data encryption (11559 vs 8838, a 30.8% lead), integer math (58156 vs 45329, 28.3%), and random string sorting (22045 vs 17397, 26.7%). Data compression also favors the i5-13420H significantly, with a 20.3% edge (209450 vs 174115). Floating-point math shows a 21.4% advantage for the i5-13420H (42806 vs 35266), while extended instructions are closer at 8.7% (12897 vs 11865). The i5-13420H also leads in PassMark multithread by 15.8% (17475 vs 15095) and physics by 5.6% (1012 vs 958).

The i3-14100's wins beyond single-thread tests are narrow. It edges out the i5-13420H in PassMark find prime numbers by 5.5% (55 vs 52), a result that aligns with its higher boost clock. Overall, the data shows the i5-13420H as the clear multi-threaded workhorse, while the i3-14100 excels in specific single-threaded and sustained-load scenarios.

Architecture Differences

The two processors share the Raptor Lake architecture and Intel's 10 nm process node, but diverge sharply in core configuration and physical design. The i5-13420H packs 8 cores and 12 threads, a hybrid arrangement typical of mobile H-series parts, while the i3-14100 is a simpler 4-core, 8-thread desktop chip. This core count differential directly explains the i5-13420H's dominance in multi-threaded PassMark tests, as it can process more parallel workloads simultaneously.

Clock speeds tell the opposite story. The i3-14100 runs at a 3.50 GHz base clock and 4.70 GHz boost, substantially higher than the i5-13420H's 2.10 GHz base and 4.60 GHz boost. The i3-14100's higher boost clock underpins its PassMark single-thread victory, though the 0.10 GHz difference is modest. The i5-13420H compensates with a 45 W TDP versus the i3-14100's 60 W, indicating the mobile part is designed for tighter thermal constraints despite its higher core count.

Cache hierarchies reveal another key split. Both share 80 KB L1 per core and 12 MB shared L3, but the L2 cache differs: the i5-13420H offers 2 MB per core, while the i3-14100 provides 1.25 MB per core. This gives the i5-13420H a larger total L2 footprint, which likely contributes to its strong data compression and encryption scores. The i3-14100 has a physically larger die at 163 mm², while the i5-13420H's die size is not specified.

Platform features separate the two further. The i5-13420H uses the Intel BGA 1744 socket and targets the mobile segment, while the i3-14100 uses Intel Socket 1700 for desktop builds. The i5-13420H supports PCIe Gen 5 with 8 lanes (CPU only), whereas the i3-14100 offers 16 lanes, providing more bandwidth for discrete GPUs. The i5-13420H features Iris Xe Graphics 80EU, a more capable integrated GPU, while the i3-14100 uses UHD Graphics 730. The i3-14100 supports ECC memory, a feature absent on the i5-13420H, and its launch MSRP is $134. Both support DDR4 and DDR5 memory over a dual-channel bus.

The Verdict

The data presents a clear choice based on workload priorities. The Intel Core i5-13420H wins 12 of 17 head-to-head benchmarks, with its largest advantages in encryption (30.8%), integer math (28.3%), and random string sorting (26.7%). It is the superior processor for multi-threaded productivity tasks, data-heavy workloads, and scenarios where its 8 cores can be fully utilized. The 12 MB shared L3 cache and larger per-core L2 cache further bolster its case for complex computational workloads.

The Intel Core i3-14100 wins 5 benchmarks, primarily in single-threaded tests and sustained rendering. Its Cinebench R23 multicore victory by 13.5% is notable, suggesting it handles prolonged, resource-intensive rendering better than the mobile chip. Its PassMark single-thread score of 3759 versus 3396 (9.7% higher) makes it the better choice for lightly-threaded applications that rely on raw clock speed. The i3-14100's 16 PCIe Gen 5 lanes also make it more suitable for desktop systems with high-bandwidth expansion needs, and its ECC memory support targets reliability-focused builds.

For users prioritizing parallel processing, data encryption, or integer-heavy computations, the i5-13420H is the data-backed winner. For those needing peak single-thread performance, sustained rendering capability, or desktop platform flexibility, the i3-14100 holds the advantage. Both processors sit at the same 72nd percentile, but they serve different market segments: the i5-13420H as a mobile workhorse, the i3-14100 as a desktop value performer.
