Intel Core i5-14400F vs Intel Core i7-12800H Comparison

The Intel Core i5-14400F and the Intel Core i7-12800H are two processors from different segments, yet their overall benchmark averages sit remarkably close together. The i5-14400F posts an average benchmark score of 32279, landing in the 83rd percentile of all CPUs, while the i7-12800H achieves 32121, placing it in the 82nd percentile. The data shows a nearly identical overall performance envelope, with the i5-14400F holding a slim 0.5% lead over the i7-12800H in average score. This makes the head-to-head comparison particularly instructive, as the two chips achieve parity through very different architectural and market positioning.

Head-to-Head Benchmarks

The benchmark results reveal a clear split in workload types, with the i5-14400F dominating most tests but the i7-12800H securing specific wins. The most dramatic difference appears in multi-core rendering. In Cinebench R23 multi-core, the i5-14400F scores 21645 against the i7-12800H’s 15283, a 41.6% advantage. This gap widens further in single-core performance, where the i5-14400F leads by 67.1% in Cinebench R23 single-core, scoring 3055 versus 1828. The i5-14400F also wins Cinebench R20 multi-core by 7.4% (9090 vs 8463) and single-core by 7.5% (1283 vs 1194). In Cinebench R15, however, the i7-12800H edges ahead in multi-core by 1.8% (2222 vs 2181), though the i5-14400F counters with a 15.8% lead in single-core (307 vs 265).

Beyond Cinebench, the i5-14400F continues its winning streak across Passmark’s synthetic suite. It leads by 15.5% in data compression (315521 vs 273247), 4.4% in data encryption (16949 vs 16234), and 21.5% in extended instructions (19937 vs 16408). Floating point math goes to the i5-14400F by a narrow 0.6% margin (61319 vs 60961), while multithreaded performance sees a 4.6% win (25470 vs 24346). Random string sorting favors the i5-14400F by 7.3% (32680 vs 30453), and single-thread tests show a 7.6% advantage (3701 vs 3440). The i5-14400F wins 13 of the 17 benchmark comparisons.

The i7-12800H secures four victories, each highlighting a different strength. In Passmark’s find prime numbers test, it wins by 15.7% (102 vs 86), a workload that appears to favor its core configuration. Integer math goes to the i7-12800H by 5.7% (86488 vs 81524), and physics performance shows a 9.5% lead (1682 vs 1523). The Cinebench R15 multi-core result is the fourth win, at 1.8%. These wins, while fewer, suggest the i7-12800H has specific advantages in integer-heavy and physics-based tasks that the broader benchmark averages do not capture.

Architecture Differences

The two processors come from different generations and target different markets, which explains the benchmark patterns. The i5-14400F belongs to the Core 14th Gen series, based on Raptor Lake architecture with the Raptor Lake-R codename. It is a desktop part using Intel Socket 1700, built on Intel’s 10 nm process with a die size of 215 mm². The i7-12800H is a Core 12th Gen mobile processor, using Alder Lake architecture with the Alder Lake-H codename, soldered via Intel BGA 1744. Its process node is also 10 nm, with a slightly larger die at 217 mm².

Core counts differ significantly. The i5-14400F has 10 cores and 16 threads, while the i7-12800H has 14 cores and 20 threads. Despite fewer cores, the i5-14400F achieves higher multi-core scores in most tests, suggesting higher per-core efficiency or clock behavior. The i5-14400F has a base clock of 2.50 GHz and a boost clock of 4.70 GHz, compared to the i7-12800H’s 2.40 GHz base and 4.80 GHz boost. The higher base clock of the i5-14400F may contribute to its single-core dominance, while the i7-12800H’s extra cores help in specific parallel workloads like prime number finding.

Cache configurations also differ. Both share the same L1 cache at 80 KB per core and the same L2 at 1.25 MB per core. The L3 cache, however, is larger on the i7-12800H at 24 MB shared, versus 20 MB shared on the i5-14400F. The i7-12800H also includes integrated graphics (Iris Xe 96EU), while the i5-14400F has none. Memory support is identical for both: DDR4 and DDR5, dual-channel. The i5-14400F supports ECC memory, a feature absent on the i7-12800H. PCIe capabilities differ, with the i5-14400F offering Gen 5 with 16 lanes (CPU only), while the i7-12800H uses Gen 4 with 20 lanes (CPU only). Both are locked multipliers, with the i5-14400F having a launch MSRP of $196.

The Verdict

The data clearly favors the Intel Core i5-14400F for most users, given its substantial wins in multi-core and single-core Cinebench tests. The 41.6% lead in Cinebench R23 multi-core and 67.1% lead in single-core are decisive for rendering, productivity, and general responsiveness. The i5-14400F also wins in 13 of 17 head-to-head tests, including data compression, encryption, and extended instructions, making it the stronger all-rounder for desktop workloads. Its 83rd percentile ranking versus the i7-12800H’s 82nd percentile reinforces this, though the overall average scores are close.

The i7-12800H is not without merit, however. Its wins in integer math, physics, and prime number finding suggest that workloads relying on these specific operations may see an advantage. The extra 4 cores and 4 threads (14 cores, 20 threads versus 10 cores, 16 threads) could benefit heavily threaded tasks that scale with core count, though the benchmark data does not consistently show this. The i7-12800H’s integrated graphics also make it a more complete package for systems without a discrete GPU, and its mobile BGA socket targets laptops rather than desktop builds.

For a desktop user, the i5-14400F is the clear choice based on benchmark results, particularly for tasks like video rendering or software compilation where the Cinebench R23 multi-core score is indicative. For a mobile user or someone needing integrated graphics, the i7-12800H offers comparable overall performance with specific wins, though its single-core deficit remains notable.

Where Each One Wins

The i5-14400F wins decisively in rendering and single-thread tasks. Its Cinebench R23 multi-core score of 21645 is far ahead of the i7-12800H’s 15283, and its single-core score of 3055 versus 1828 shows a massive 67.1% advantage. Data compression (315521 vs 273247) and extended instructions (19937 vs 16408) also favor the i5-14400F, making it ideal for file archiving, encryption, and SIMD-heavy applications. Its wins in floating point math, multithreaded Passmark, and random string sorting further cement its position for general desktop workloads. The i5-14400F also has the advantage of a higher base clock (2.50 GHz vs 2.40 GHz) and ECC memory support, which matters for data integrity.

The i7-12800H wins in specific compute patterns. Its Passmark find prime numbers score of 102 versus 86 indicates an advantage in prime-heavy calculations, likely due to its 14 cores. Integer math (86488 vs 81524) and physics (1682 vs 1523) also go to the i7-12800H, suggesting strengths in simulation and integer-heavy logic. The Cinebench R15 multi-core win (2222 vs 2181) is narrow but shows that in some older multi-threaded tests, the i7-12800H can edge ahead. Its integrated graphics and larger L3 cache (24 MB vs 20 MB) provide additional capabilities beyond raw CPU benchmarks, making it a better fit for mobile systems where a discrete GPU is absent.
