Intel Core 7 240H vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core i5-14400 and the Intel Core 7 240H shows a clear split. The desktop part wins 12 of 17 recorded tests, while the mobile chip takes 5. The margins tell the story: the Core i5-14400 dominates in single-threaded and multi-threaded rendering, while the Core 7 240H counters in a few specific workloads.

The largest single victory for the Core i5-14400 comes in Cinebench R23 single-core, where it scores 3009 against 1719, a 75% advantage. This is the widest gap in the entire dataset. The Core i5-14400 also leads Cinebench R23 multi-core by 35.2%, posting 21315 versus 15764. These two results alone establish the desktop chip as the stronger processor for CPU-bound rendering tasks.

Cinebench R15 multi-core is the exception to the pattern. Here the Core 7 240H wins with 2360 against 2148, a 9% edge. That result reverses the R20 and R23 multi-core outcomes, where the Core i5-14400 leads by 4.6% and 35.2% respectively. The older R15 test favors the mobile part, but the newer iterations swing decisively toward the desktop chip.

Single-core results in Cinebench R15 and R20 also favor the Core i5-14400. In R15 single-core, the score is 303 versus 249, a 21.7% margin. In R20 single-core, the gap narrows to 4.6% with 1263 against 1208. The Core 7 240H's higher boost clock of 5.20 GHz does not translate into a single-core win in any Cinebench generation.

The PassMark suite paints a similar picture. The Core i5-14400 wins data compression by 15.9% (314995 versus 271774), data encryption by 10.4% (16731 versus 15155), extended instructions by 17.3% (19816 versus 16897), floating point math by 4.5% (61549 versus 58905), integer math by 2% (82017 versus 80396), multithread by 4.6% (25080 versus 23975), and random string sorting by 12.1% (32346 versus 28866). These are consistent, moderate advantages across arithmetic and memory-bound workloads.

The Core 7 240H claims three PassMark tests. It wins find prime numbers with 102 versus 80, a 21.6% margin. It wins physics with 1723 against 1396, a 19% advantage. It also edges out the single-thread test with 3782 versus 3741, a modest 1.1% lead. The physics result is notable because it suggests the mobile part handles simulated rigid-body dynamics better, despite losing most other compute tests.

The overall win tally is 12 for the Core i5-14400 and 5 for the Core 7 240H. The average benchmark score for the Core i5-14400 sits at 32115, while the Core 7 240H records 31483. Both processors land at the 82nd percentile against all CPUs in the database. The Core i5-14400's nearest rival is the Intel Core i7-12800H with an average score of 32121, a 0% delta. The Core 7 240H's closest competitor is the Intel Core Ultra 3 205 at 31473, also a 0% delta.

Where Each One Wins

The Intel Core i5-14400 is the clear choice for rendering workloads. Its Cinebench R23 multi-core score of 21315 is 35.2% ahead of the Core 7 240H, and its R23 single-core score of 3009 is 75% higher. For content creation tasks that rely on Cinebench-style rendering, the desktop chip delivers substantially more performance. The data also shows consistent wins in data compression, encryption, extended instructions, floating point math, integer math, multithread, and random string sorting. Any workload that stresses arithmetic throughput, memory bandwidth, or encryption will favor the Core i5-14400.

The Core 7 240H wins in a narrower set of scenarios. Its PassMark physics score of 1723 is 19% higher than the Core i5-14400's 1396, indicating better performance in physics simulation workloads. It also wins find prime numbers with a 21.6% edge, which points to strength in prime-number generation tasks. The single-thread PassMark result (3782 versus 3741) is a marginal win, too small to be meaningful for most applications. In Cinebench R15 multi-core, the mobile chip leads by 9%, but that advantage disappears in the R20 and R23 versions of the same test.

For users who prioritize the latest Cinebench versions, the Core i5-14400 is the stronger option. For those running physics simulations or prime-number computations, the Core 7 240H offers a measurable benefit. The overall pattern is that the Core i5-14400 wins the majority of workload categories, while the Core 7 240H excels only in specific niches.

Specification Differences

The two processors share several core specifications. Both have 10 cores and 16 threads. Both have a base clock of 2.50 GHz. Both use 10 nm process technology from Intel. Both support DDR4 and DDR5 memory with a dual-channel memory bus. Both are active production parts with locked multipliers.

Key differences appear in other fields. The Core i5-14400 has a boost clock of 4.70 GHz, while the Core 7 240H boosts to 5.20 GHz. The desktop chip carries a TDP of 65 watts, whereas the mobile chip is rated at 45 watts. The socket differs: Intel Socket 1700 for the Core i5-14400, Intel BGA 1744 for the Core 7 240H. The Core i5-14400 supports ECC memory; the Core 7 240H does not. PCIe lane counts differ: the Core i5-14400 provides Gen 5 with 16 lanes (CPU only), while the Core 7 240H provides Gen 5 with 8 lanes (CPU only). Integrated graphics also differ: UHD Graphics 730 on the Core i5-14400 versus Iris Xe Graphics 64EU on the Core 7 240H. The Core i5-14400 has a die size of 215 mm², while the Core 7 240H has no recorded die size. The Core i5-14400 was released in January 2024, the Core 7 240H in December 2024. The launch MSRP for the Core i5-14400 is $221, and for the Core 7 240H it is $502.

Architecture Differences

Both processors are built on Raptor Lake architecture, but they come from different sub-families. The Core i5-14400 uses the Raptor Lake-R codename, part of the Core i5 (Raptor Lake Refresh) generation. The Core 7 240H uses the Raptor Lake-H codename, part of the Core 7 (Raptor Lake Refresh) generation. Both are manufactured by Intel on a 10 nm process.

Cache configurations differ. The L1 cache is identical at 80 KB per core. The L2 cache differs: the Core i5-14400 has 1.25 MB per core, while the Core 7 240H has 2 MB per core. The L3 cache also differs: the Core i5-14400 has 20 MB shared, while the Core 7 240H has 24 MB shared. The larger L2 and L3 caches on the Core 7 240H give it a structural advantage for cache-sensitive workloads, but the benchmark data shows that advantage does not overcome the Core i5-14400's overall performance lead in most tests.

Memory support is the same (DDR4 and DDR5, dual-channel), but ECC support is present only on the Core i5-14400. PCIe configuration differs, with the desktop part offering double the CPU-attached Gen 5 lanes. Integrated graphics capabilities are different, with the Core 7 240H using Iris Xe Graphics 64EU and the Core i5-14400 using UHD Graphics 730. The Core 7 240H lacks a recorded die size, while the Core i5-14400 measures 215 mm².

The Verdict

The data points to the Intel Core i5-14400 as the stronger processor for most workloads. It wins 12 of 17 head-to-head benchmarks, including all Cinebench single-core tests and the R20 and R23 multi-core tests. Its average benchmark score of 32115 is higher than the Core 7 240H's 31483. The 75% lead in Cinebench R23 single-core and the 35.2% lead in R23 multi-core are decisive margins. Users who run Cinebench-based rendering, data compression, encryption, or heavy arithmetic workloads should choose the Core i5-14400.

The Core 7 240H is not without merit. It wins Cinebench R15 multi-core, PassMark physics, PassMark find prime numbers, and PassMark single-thread. The physics win (19% ahead) and the prime number win (21.6% ahead) are meaningful for those specific tasks. Its 5.20 GHz boost clock is the highest of the two, and its 45 watt TDP makes it a lower-power option. The larger L2 and L3 caches (2 MB per core L2, 24 MB L3) provide a structural edge for cache-heavy operations.

For a desktop system with a socket 1700 board, the Core i5-14400 fits the platform and delivers better overall benchmark results. For a mobile system with a BGA 1744 socket, the Core 7 240H is the intended part, and it offers competitive performance in physics and prime-number workloads. The market segments differ, so the choice depends on the platform. On raw performance data alone, the Core i5-14400 is ahead in the majority of tests, with a higher average benchmark score and a 75% single-core margin that no other result matches. The Core 7 240H holds its own in niche tasks but trails overall.
