Intel Core i7-14701E vs Intel Core Ultra 5 245HX Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 5 245HX dominates this comparison, winning all 17 recorded benchmark comparisons. The Core i7-14701E does not win a single head-to-head test. The largest margins appear in encryption and prime number workloads, while the smallest gap is in single-thread performance.

In Cinebench tests, the Ultra 5 245HX leads by a consistent margin. The R15 multicore result shows 3261 versus 2237, a 31.4% advantage. The R20 multicore score of 13590 against 9321 represents the same 31.4% gap. The R23 multicore result of 32358 versus 22195 also lands at 31.4%. Single-core results follow the same pattern: R15 single-core at 460 versus 315, R20 single-core at 1918 versus 1315, and R23 single-core at 4568 versus 3133, each a 31.4% difference. This consistency across three Cinebench generations suggests a fundamental performance-per-clock advantage rather than a workload-specific quirk.

PassMark tests show a wider spread of deltas. Data encryption favors the Ultra 5 245HX by 50.5%, with scores of 30022 versus 14862. Prime number finding shows a 51% lead, 359 versus 176. Floating point math delivers 120735 against 61873, a 48.8% gap. Extended instructions measure 31212 versus 18528, a 40.6% difference. Random string sorting comes in at 47616 versus 29158, a 38.8% lead.

The narrowest margins appear in integer-heavy and single-thread workloads. Integer math shows 92150 versus 81325, an 11.7% lead for the Ultra 5. PassMark single-thread scores sit at 4481 versus 4305, only a 3.9% gap. Physics scores are close as well: 2526 versus 2399, a 5% difference. These results indicate that the two processors are much closer when the workload does not scale with core count or advanced instruction throughput.

The average benchmark score tells a similar story. The Core i7-14701E records 33206, while the Ultra 5 245HX records 48287. The percentile rankings place the i7-14701E at 83rd percentile among all CPUs, while the Ultra 5 245HX sits at 90th percentile.

Where Each One Wins

The Core i7-14701E has no benchmark wins in the recorded data. Every test, from Cinebench multicore to PassMark integer math, favors the Ultra 5 245HX. However, the size of the advantage varies meaningfully by workload type.

For memory-bound and multi-threaded workloads, the Ultra 5 245HX is decisively faster. Data compression scores 393071 versus 282939, a 28% lead. Multithread performance measures 38069 versus 26112, matching the 31.4% Cinebench gap. These workloads benefit from the Ultra 5's higher core count and newer memory interface.

For single-thread responsiveness, the gap narrows considerably. PassMark single-thread scores differ by only 3.9%. Cinebench single-core tests show a larger 31.4% gap, but the PassMark result suggests that day-to-day single-thread tasks are closer in practice. Physics simulation also shows a modest 5% difference.

Encryption and extended instruction workloads show the largest gaps, at 50.5% and 40.6% respectively. These tests likely benefit from the Ultra 5's newer microarchitecture and instruction set extensions. The i7-14701E's older Raptor Lake design cannot match this throughput.

The Verdict

The data clearly favors the Intel Core Ultra 5 245HX across every measured benchmark. It holds a 31.4% lead in all Cinebench tests, a 50.5% lead in encryption, and a 51% lead in prime number finding. The only area where the two chips approach parity is PassMark single-thread performance, where the Ultra 5 leads by just 3.9%.

The Core i7-14701E is a desktop processor with 8 cores and 16 threads, based on Raptor Lake architecture. The Ultra 5 245HX is a mobile processor with 14 cores and 14 threads, based on Arrow Lake architecture. Despite the i7-14701E's higher boost clock of 5.40 GHz versus 5.10 GHz, the Ultra 5's newer 3 nm process node and higher base clock of 3.10 GHz versus 2.60 GHz deliver superior results in every test.

For users choosing between these two parts strictly on measured performance, the Ultra 5 245HX is the stronger option in every recorded workload. The i7-14701E does retain advantages in platform compatibility, supporting DDR4 memory and ECC memory, which the Ultra 5 does not. But on raw benchmark scores, there is no contest.
