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

The Intel Core i5-14400 and Intel Core i7-13705H are both Raptor Lake parts, but they target entirely different segments: one is a desktop chip, the other a mobile processor. The data reveals a clear split: the i5-14400 dominates in most computational workloads, while the i7-13705H claims specific, niche victories. The i5-14400 wins 13 of the 17 head-to-head benchmarks, while the i7-13705H takes only 4. However, the average benchmark scores are nearly identical—32115 for the i5-14400 versus 32076 for the i7-13705H—placing both at the 82nd percentile of all CPUs. This parity in overall standing, despite the lopsided win count, indicates that the i7-13705H’s victories come in areas that heavily weight its unique configuration.

Where Each One Wins

The Intel Core i5-14400 is the clear winner for rendering, content creation, and general productivity. In Cinebench tests, it posts a commanding lead, with multicore scores roughly 33% higher across R15, R20, and R23. This makes it the stronger choice for video editing, 3D modeling, and any workflow that leverages multi-threaded CPU rendering. It also wins in data compression (314995 vs 273720, a 15.1% lead), extended instruction sets (19816 vs 15810, a 25.3% lead), and random string sorting (32346 vs 29285, a 10.5% lead). Its single-thread performance is superior as well, leading by 7.4% in PassMark single-thread scores (3741 vs 3483) and by 33.3% in Cinebench R23 single-core. For the majority of users, the i5-14400 is the more versatile and faster processor.

The Intel Core i7-13705H, despite being a mobile chip, wins in a few specialized areas. Its most significant victory is in PassMark physics, where it scores 1854 against the i5-14400’s 1396—a 24.7% advantage. It also wins in integer math (85927 vs 82017, a 4.6% lead) and floating-point math (63064 vs 61549, a 2.4% lead). The most unusual result is in prime number finding, where the i7-13705H scores 116 versus a mere 80 for the i5-14400, a 31% difference. These wins suggest the i7-13705H has a particular strength in mathematical and scientific workloads that rely on integer or floating-point operations, though the i5-14400’s massive lead in other areas makes it the better all-rounder.

Specification Differences

The two processors diverge significantly in their physical and platform specifications. The i5-14400 is a desktop chip with a TDP of 65 watts, while the i7-13705H is a mobile part with a lower 45-watt TDP. The i5-14400 uses the Intel Socket 1700, whereas the i7-13705H uses the Intel BGA 1744 socket. The core counts differ, with the i7-13705H offering 14 cores and 20 threads versus 10 cores and 16 threads for the i5-14400. Base clocks are close (2.50 GHz for the i5-14400, 2.40 GHz for the i7-13705H), but the boost clock favors the i7-13705H at 5.00 GHz versus 4.70 GHz.

Cache configurations also differ. Both have 80 KB of L1 cache per core, but the L2 cache is larger on the i7-13705H at 2 MB per core versus 1.25 MB per core. The shared L3 cache is also bigger on the i7-13705H, at 24 MB versus 20 MB. The die size is larger for the mobile chip at 257 mm², compared to 215 mm² for the desktop part. PCIe lanes are another differentiator: the i5-14400 offers 16 Gen 5 lanes (CPU only), while the i7-13705H provides 8 Gen 5 lanes. The i5-14400 supports ECC memory, which the i7-13705H does not. Finally, the integrated graphics differ, with the i5-14400 featuring UHD Graphics 730 and the i7-13705H featuring Iris Xe Graphics 96EU.

Architecture Differences

Despite both being built on Intel’s 10nm process and sharing the Raptor Lake architecture, these are distinct dies. The i5-14400 uses the Raptor Lake-R die, which measures 215 mm², while the i7-13705H uses the Raptor Lake-H die, which is larger at 257 mm². The larger die on the mobile chip accommodates the additional cores and cache. The i5-14400 is from the Core 14th Gen series, specifically the Raptor Lake Refresh generation, while the i7-13705H is from the Core 13th Gen series, based on the original Raptor Lake-H design.

The cache hierarchy differs in size, with the i7-13705H having more L2 and L3 cache per core. Both support DDR4 and DDR5 memory in a dual-channel configuration. The i5-14400’s PCIe implementation offers 16 Gen 5 lanes, while the i7-13705H has 8 Gen 5 lanes, reflecting their desktop and mobile design goals. The i5-14400 also uniquely supports ECC memory, a feature absent on the i7-13705H. The integrated graphics are different tiers: UHD Graphics 730 on the desktop part versus the higher-end Iris Xe Graphics 96EU on the mobile part. The release dates are also different, with the i7-13705H launching in January 2023 and the i5-14400 in January 2024. The launch MSRP of the i5-14400 is $221, while the i7-13705H launched at $502.
