Architecture Differences

Both processors belong to Intel's Core 14th Gen series and share the Raptor Lake architecture, specifically the Raptor Lake-R codename. The manufacturing process is identical at 10 nm, built by Intel's own foundry. Despite these commonalities, the two chips diverge significantly in internal configuration.

The core layout is the first major difference. The Core i5-14400F contains 10 cores and 16 threads, while the Core i9-14901KE contains 8 cores and 16 threads. This means the i5 has two additional physical cores but relies on its thread scheduling to reach the same thread count as the i9. The i9 compensates with much higher clock speeds: a base clock of 3.80 GHz versus 2.50 GHz, and a boost clock of 5.80 GHz versus 4.70 GHz. The i9's boost advantage of over 1 GHz is substantial for workloads that scale with frequency.

Cache allocation also differs. Both chips use 80 KB of L1 cache per core, but the L2 cache per core is 1.25 MB on the i5-14400F and 2 MB on the i9-14901KE. The shared L3 cache is 20 MB on the i5 and 36 MB on the i9. The i9 therefore carries a considerably larger total cache footprint, which benefits workloads with large working sets that can stay resident on-chip.

The die size reflects the different configurations. The i5-14400F has a die size of 215 mm², while the i9-14901KE has a die size of 257 mm². The larger die on the i9 accommodates the bigger L3 cache and higher-core-count design. Both processors are produced on the same 10 nm node by Intel, so the die size difference comes from the internal layout rather than process changes.

The integrated graphics situation separates the two as well. The i9-14901KE includes Intel UHD Graphics 770, while the i5-14400F has no integrated graphics at all, listed as N/A. This affects system configuration: the i5 requires a discrete graphics card for display output, whereas the i9 can drive a display without a separate GPU.

The multiplier lock status differs. The i5-14400F has a locked multiplier, while the i9-14901KE has an unlocked multiplier. This makes the i9 more flexible for overclocking scenarios, assuming the rest of the platform supports it. The i5's locked multiplier limits frequency adjustment to base clock manipulation or platform limits.

The release dates differ by several months. The i5-14400F was released on January 7, 2024, while the i9-14901KE was released on June 30, 2024. Both are marked as active in production status and target the desktop market segment.

The part numbers confirm the distinct SKUs: SRN3RSRN47 for the i5-14400F and Q49DSRNJC for the i9-14901KE. The i5 has a launch MSRP of $196, while the i9 has no recorded launch MSRP in the database.

The Verdict

The benchmark data in the database contains complete measurements for the Intel Core i5-14400F but no recorded benchmark scores for the Intel Core i9-14901KE. The i5-14400F has an average benchmark score of 32,279 and sits in the 83rd percentile among all CPUs. The i9-14901KE has an average benchmark score of 0 and a 50th percentile ranking, which reflects the absence of recorded data rather than actual performance.

The i5-14400F demonstrates strong measured performance across multiple test suites. Its nearest rivals in the database include the AMD Ryzen 7 PRO 8840U with an average score of 32,233, the Intel Core i9-11900 with 32,226, the AMD Ryzen 7 6800HS with 32,354, and the Intel Core i7-12800H with 32,121. The i5-14400F sits within roughly half a percent of these processors, indicating comparable performance to that group.

For the i9-14901KE, the hardware specifications suggest a processor designed for high-frequency workloads. Its 5.80 GHz boost clock, 36 MB of L3 cache, and 2 MB L2 per core are the highest figures in its class among the two chips compared here. The 8-core, 16-thread layout with unlocked multiplier targets single-thread performance and overclocking flexibility.

The choice between these processors depends on what the data can support. The i5-14400F has verified benchmark results and a known launch MSRP. The i9-14901KE offers higher clocks, more cache, integrated graphics, and an unlocked multiplier, but the database contains no performance measurements for it. Without recorded benchmark scores, the i9's actual performance relative to the i5 cannot be quantified from the available data.

Users who require a processor with verified performance numbers and a lower power envelope may favor the i5-14400F. Users who prioritize maximum boost frequency, larger cache, integrated graphics, and overclocking capability may consider the i9-14901KE, but they should note the absence of benchmark validation in the database. The i5's 83rd percentile ranking places it above a substantial majority of all CPUs in the database, while the i9's 50th percentile is a placeholder value pending measurement data.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Intel Core i5-14400F and the Intel Core i9-14901KE. The head-to-head benchmark array is empty, and the win counts for both processors are zero.

The i5-14400F does have a full set of individual benchmark scores recorded. In Cinebench R15 multicore, it scores 2,181 points, with a single-core score of 307. In Cinebench R20, the multicore score is 9,090 and the single-core score is 1,283. In Cinebench R23, the multicore result is 21,645 and the single-core result is 3,055. These Cinebench figures show a multicore-to-single-core ratio that scales with the 10-core, 16-thread configuration.

Geekbench results for the i5-14400F show a multicore score of 11,268 and a single-core score of 2,058. PassMark tests provide additional detail. The data compression score is 315,521, data encryption scores 16,949, and extended instructions score 19,937. Prime number finding scores 86, floating point math scores 61,319, and integer math scores 81,524. The multithread score is 25,470, physics scores 1,523, random string sorting scores 32,680, and single-thread performance scores 3,701.

The i9-14901KE has no benchmark scores recorded in any test. Its average benchmark score is listed as 0, and its percentile versus all CPUs is 50, which is the median default in the absence of data. The nearest rivals array is empty for the i9, so there are no comparison points from the database.

Given the absence of measured data for the i9-14901KE, a quantitative head-to-head comparison cannot be constructed from the database. The i5-14400F's scores can be compared against its own nearest rivals instead. The AMD Ryzen 7 PRO 8840U scores 32,233 on average, which is a 0.1 percent difference from the i5-14400F. The Intel Core i9-11900 scores 32,226, a 0.2 percent difference. The AMD Ryzen 7 6800HS scores 32,354, which is 0.2 percent higher than the i5. The Intel Core i7-12800H scores 32,121, a 0.5 percent lower result. These margins place the i5-14400F in a tight performance band around its direct competitors.

The i9-14901KE's hardware specifications imply a different performance profile, but the database cannot confirm it. The higher boost clock and larger cache would typically favor single-thread and cache-sensitive workloads, while the lower core count might reduce multicore throughput relative to the i5. These are qualitative inferences from the specification fields, not measured results.

The i5-14400F's 83rd percentile ranking among all CPUs in the database indicates that its measured average score of 32,279 exceeds the majority of recorded processors. The i9-14901KE's 50th percentile is a placeholder consistent with zero recorded measurements. Until benchmark data is added for the i9, the database supports no direct performance comparison between the two processors.
