Intel Core i5-14400F vs Intel Core i7-13705H Comparison

The Intel Core i5-14400F and Intel Core i7-13705H represent two very different interpretations of Intel's Raptor Lake architecture: one is a desktop part with a 65 W TDP, the other a mobile part with a 45 W TDP. The benchmark data shows a clear overall winner in the i5-14400F, which takes 13 of the 17 head-to-head comparisons, but the i7-13705H is far from a pushover, winning several math-heavy workloads. The i5-14400F’s average benchmark score of 32279 places it at the 83rd percentile of all CPUs, while the i7-13705H’s 32076 average sits at the 82nd percentile—a razor-thin difference in overall standing that masks the significant per-test swings.

Head-to-Head Benchmarks

The most dramatic story in the data is the Cinebench sweep. The i5-14400F wins every single Cinebench test, and it does so by a remarkably consistent margin. In Cinebench R23 multi-core, the i5-14400F scores 21645 against the i7-13705H’s 15998, a 35.3% advantage. That same 35.3% delta appears in Cinebench R15 multi-core (2181 vs 1612), R20 multi-core (9090 vs 6719), and even in single-core tests—R23 single-core shows 3055 vs 2258, and R15 single-core shows 307 vs 227. The consistency of this 35.3% gap across both single- and multi-threaded render workloads is unusual. It suggests the i5-14400F’s higher boost clock of 4.70 GHz, combined with its desktop socket design, delivers a fundamental per-thread advantage that the i7-13705H’s 5.00 GHz boost cannot overcome in practice. The i7-13705H’s extra four cores (14 vs 10) and four additional threads (20 vs 16) do not translate into multi-core render wins; the i5-14400F’s 20 MB of L3 cache versus 24 MB on the i7 does not hurt it here.

Outside of Cinebench, the i5-14400F continues to lead in several Passmark workloads, though with smaller margins. In data compression, the i5-14400F scores 315521 versus 273720, a 15.3% win. Extended instructions favor the i5-14400F by 26.1% (19937 vs 15810). Random string sorting shows an 11.6% win for the i5-14400F (32680 vs 29285), and data encryption is close, with the i5-14400F ahead by just 3.8% (16949 vs 16324). Single-thread performance in Passmark also favors the i5-14400F, scoring 3701 against 3483, a 6.3% margin. The multithread Passmark score is closer, with the i5-14400F winning by 4.1% (25470 vs 24460), a much narrower gap than the Cinebench multi-core results would suggest.

The i7-13705H’s four wins are all in Passmark math workloads, and they are not trivial. The biggest is find prime numbers, where the i7-13705H scores 116 versus the i5-14400F’s 86, a 25.9% blowout in favor of the mobile chip. Physics simulation also goes to the i7-13705H by 17.9% (1854 vs 1523). Integer math sees the i7-13705H ahead by 5.1% (85927 vs 81524), and floating point math is nearly even, with the i7-13705H winning by just 2.8% (63064 vs 61319). These results indicate that the i7-13705H’s higher core count and larger L2 cache (2 MB per core vs 1.25 MB per core) give it an edge in certain integer-heavy and physics-simulation tasks, even though it loses the overall multithread Passmark test.

Where Each One Wins

The i5-14400F is the definitive choice for rendering and content creation workloads. Its 35.3% lead across every Cinebench version—R15, R20, and R23, in both single- and multi-core—makes it the obvious pick for anyone running 3D rendering, video encoding, or photo editing suites that rely on those engines. The data also shows it is better for data compression tasks, scoring 15.3% higher, and for extended instruction workloads, where it is 26.1% ahead. For general productivity, the i5-14400F’s 6.3% single-thread advantage in Passmark means snappier application launches and better responsiveness in lightly-threaded software. It also wins the Passmark multithread test by 4.1%, so even in heavily threaded non-render workloads, it holds the edge.

The i7-13705H should be the pick for specific math-heavy and simulation tasks. Its 25.9% victory in find prime numbers and 17.9% win in physics simulation point to strengths in scientific computing, financial modeling, or physics engines. The integer math win of 5.1% and floating point math win of 2.8% suggest it handles raw number-crunching loops better than the i5-14400F. This is likely a function of its 14 cores and larger 24 MB L3 cache, which allow it to feed more data to the execution units in parallel. For users who prioritize these specific workloads over general rendering, the i7-13705H is not a bad choice, but its wins are niche compared to the i5-14400F’s broad dominance.

Specification Differences

The two processors differ in almost every fundamental specification. The i5-14400F is a desktop chip on the Intel Socket 1700 platform, while the i7-13705H is a mobile chip on the Intel BGA 1744 socket. Core counts differ: the i5-14400F has 10 cores and 16 threads, while the i7-13705H has 14 cores and 20 threads. Base clocks are similar, with the i5-14400F at 2.50 GHz and the i7-13705H at 2.40 GHz, but the boost clocks tell a different story—the i7-13705H boosts to 5.00 GHz, higher than the i5-14400F’s 4.70 GHz. The TDP is a major split: the i5-14400F is rated at 65 W, while the i7-13705H is rated at 45 W. Cache configurations also differ, with the i5-14400F offering 1.25 MB of L2 per core and 20 MB of shared L3, versus the i7-13705H’s 2 MB of L2 per core and 24 MB of shared L3. The i5-14400F has 16 PCIe Gen 5 lanes (CPU only), while the i7-13705H has 8. The i5-14400F supports ECC memory, which the i7-13705H does not. Finally, the i7-13705H includes integrated Iris Xe Graphics with 96 execution units, while the i5-14400F has no integrated graphics. The die sizes also differ, with the i5-14400F at 215 mm² and the i7-13705H at 257 mm².

Architecture Differences

Both chips are built on Intel’s Raptor Lake architecture and fabricated on Intel’s 10 nm process, but they belong to different product generations and market segments. The i5-14400F is a Core 14th Gen desktop part, codenamed Raptor Lake-R, released on January 7, 2024. The i7-13705H is a Core 13th Gen mobile part, codenamed Raptor Lake-H, released on January 3, 2023. The 10-core i5-14400F is a more streamlined design with a smaller die, while the 14-core i7-13705H has a larger die, likely to accommodate the additional cores and the integrated graphics unit. The i7-13705H’s larger 2 MB per-core L2 cache is a notable architectural difference, as it doubles the L2 capacity per core compared to the i5-14400F’s 1.25 MB. The i7-13705H also has a larger L3 cache at 24 MB versus 20 MB. The presence of integrated graphics on the i7-13705H is a significant architectural feature, making it a self-contained mobile solution, whereas the i5-14400F is designed to pair with a discrete GPU. The production status for both is listed as Active, and neither has an unlocked multiplier.

The Verdict

The data is unambiguous: the Intel Core i5-14400F is the faster processor in the vast majority of workloads. With 13 wins out of 17 head-to-head tests, including a perfect sweep of all Cinebench tests by 35.3%, it is the superior choice for rendering, video editing, and general productivity. Its 83rd percentile ranking versus the i7-13705H’s 82nd percentile confirms this at a high level, even though the average scores are close. For a desktop user building a new system, the i5-14400F’s 65 W TDP and Socket 1700 compatibility make it a straightforward pick, and its ECC memory support is a bonus for workstation builds that require error correction.

The i7-13705H should only be chosen by users with a specific, math-intensive workload that aligns with its four wins. If your primary tasks involve prime number calculations, physics simulation, or raw integer math, the i7-13705H’s 25.9% lead in find prime numbers and 17.9% lead in physics justify its selection. However, for any mixed-use scenario, the i5-14400F’s dominance in Cinebench, data compression, and single-thread tasks makes it the safer, faster option. The i7-13705H’s integrated graphics and 45 W TDP make it a reasonable choice for a compact mobile workstation, but on raw processing power, the i5-14400F is the clear winner in this comparison.
