Intel Core i5-14400 vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear split between these two Intel 14th Gen desktop processors. The Intel Core i7-14701E wins 12 of the 17 recorded comparisons, while the Intel Core i5-14400 takes 5 wins. The i7-14701E delivers consistent multi-core and single-core advantages in rendering and compute workloads, but the i5-14400 counters in several specialized data-processing tests.

The i7-14701E leads across the entire Cinebench suite. In Cinebench R15 multi-core, it scores 2237 against 2148 for the i5-14400, a 4% margin. The R20 multi-core test shows 9321 versus 8952, again 4% ahead. Cinebench R23 multi-core records 22195 for the i7-14701E versus 21315 for the i5-14400, a 4% gap.

The consistent 4% delta across all three Cinebench versions indicates a uniform clock-speed advantage rather than workload-specific behavior.

PassMark multi-thread testing shows the i7-14701E at 26112 versus 25080, a 4% lead. The physics subtest is a major differentiator: the i7-14701E scores 2399, which is 41.8% higher than the i5-14400's 1396. Prime number finding follows with a 176 versus 80 result, a 54.5% advantage for the i7-14701E. Floating-point math is nearly even, with 61873 versus 61549, a 0.5% edge for the i7-14701E. Single-thread performance is strongly in favor of the i7-14701E: 4305 versus 3741, a 13.1% lead.

The i5-14400 takes its wins in data-oriented workloads. Data compression shows 314995 versus 282939, an 11.3% advantage. Data encryption records 16731 versus 14862, a 12.6% lead. Extended instructions score 19816 versus 18528, 7% higher. Random string sorting is 32346 versus 29158, a 10.9% edge. Integer math is the narrowest i5-14400 win: 82017 versus 81325, just 0.9% ahead.

These results indicate the i7-14701E is the stronger general-purpose processor, particularly for physics simulation, prime-number computation, and any workload that scales with clock speed. The i5-14400's wins in compression, encryption, and sorting suggest its memory subsystem or core scheduling favors those specific instruction patterns.

Architecture Differences
