Head-to-Head Benchmarks

The benchmark data records 17 head-to-head comparisons between the Intel Core i5-14450HX and the Intel Core i7-14701E. The Core i7-14701E wins 15 of those tests, while the Core i5-14450HX wins only 2. The average benchmark score for the Core i7-14701E is 33206, which places it in the 83rd percentile of all CPUs. The Core i5-14450HX records an average score of 32040, placing it in the 82nd percentile.

The most decisive wins for the Core i7-14701E come in the PassMark physics test and the prime number finding test. In physics, the Core i7-14701E scores 2399 against 1475 for the Core i5-14450HX, a delta of -38.5% from the perspective of the i5. In prime number finding, the score is 176 versus 98, a delta of -44.3%. These are the two largest gaps in the entire comparison, indicating a substantial advantage in workloads that stress integer calculation and physics simulation.

The Cinebench suite shows a consistent pattern. Across all six Cinebench tests (R15, R20, and R23, each in multicore and singlecore variants), the Core i7-14701E leads by roughly 9.4% to 9.5%. For example, in Cinebench R23 multicore, the i7-14701E scores 22195 against 20108 for the i5-14450HX. In Cinebench R23 singlecore, the scores are 3133 and 2838 respectively. The consistency of these deltas suggests a uniform clock-speed or microarchitectural advantage rather than a workload-specific one.

The Core i5-14450HX does secure two wins. In PassMark data encryption, it scores 15574 against 14862 for the i7-14701E, a delta of 4.8%. In PassMark random string sorting, it scores 29565 against 29158, a delta of 1.4%. Both wins are narrow, and neither approaches the magnitude of the i7-14701E's advantages.

In the remaining PassMark tests, the i7-14701E leads with varying margins. Floating point math shows a 6.2% lead (61873 versus 58037). Extended instructions shows a 7.1% lead (18528 versus 17207). Integer math shows a 3.7% lead (81325 versus 78330). Multithread shows a 9.3% lead (26112 versus 23680). Single-thread shows the second-largest gap at 15.4% (4305 versus 3643). Data compression is nearly tied, with the i7-14701E leading by only 1.6% (282939 versus 278538).

Where Each One Wins

The Core i7-14701E dominates across nearly every measured category. Its wins in Cinebench multicore tests indicate strong sustained performance for rendering and CPU-bound productivity workloads. The 9.4% lead in Cinebench R23 multicore is particularly relevant for video encoding and 3D rendering tasks. The single-core wins in both Cinebench and PassMark single-thread tests show that the i7-14701E also handles lightly threaded applications, such as older games or spreadsheet calculations, with more headroom.

The 38.5% lead in PassMark physics and the 44.3% lead in prime number finding point to a specific strength in integer-heavy, branch-predictor-sensitive workloads. These are often found in scientific simulation, cryptography, and certain financial modeling tasks. The 15.4% lead in PassMark single-thread reinforces that the i7-14701E has a clear clock-speed advantage, which benefits any workload that cannot use multiple cores effectively.

The Core i5-14450HX wins only in data encryption and random string sorting. The encryption win is modest at 4.8%, suggesting that the i5-14450HX has a slight edge in AES-related operations or similar cryptographic routines. The random string sorting win is even smaller at 1.4%, and it may be within run-to-run variance. Outside of these two narrow cases, the i5-14450HX does not record a single benchmark win.

For users prioritizing multi-threaded throughput, the i7-14701E delivers a uniform advantage. For users who specifically work with encrypted data or string-heavy sorting algorithms, the i5-14450HX offers a small but measurable benefit. The overall record, however, is heavily skewed toward the i7-14701E.

Architecture Differences

Both processors belong to the Core 14th Gen series and share the Raptor Lake architecture. The foundry is Intel for both, and both use a 10 nm process node. The die size is identical at 257 mm² for each. Both support DDR4 and DDR5 memory with a dual-channel bus, and both support ECC memory. Both use PCIe Gen 5 with 16 lanes from the CPU.

The core configurations differ. The Core i5-14450HX has 10 cores and 16 threads, while the Core i7-14701E has 8 cores and 16 threads. The thread count is identical, but the i5-14450HX relies on more physical cores to reach that thread count, likely through a mix of performance and efficiency cores. The i7-14701E achieves the same thread count with fewer cores, which indicates a higher performance-core count.

The L1 cache is 80 KB per core for both, and the L2 cache is 2 MB per core for both. The L3 cache differs significantly: the i5-14450HX has 20 MB shared, while the i7-14701E has 33 MB shared. That 13 MB difference in L3 capacity is a major architectural differentiator and likely contributes to the i7-14701E's lead in cache-sensitive workloads.

Clock speeds also favor the i7-14701E. The base clock is 2.60 GHz versus 2.40 GHz, and the boost clock is 5.40 GHz versus 4.80 GHz. The i7-14701E has a 0.60 GHz boost advantage, which explains its consistent single-thread lead. The i5-14450HX has a higher TDP ceiling at 55 W versus 65 W for the i7-14701E, but the i7-14701E still posts higher scores in nearly every test.

The integrated graphics differ. The i5-14450HX uses UHD Graphics 710, while the i7-14701E uses UHD Graphics 770. The i7-14701E also has a locked multiplier, whereas the i5-14450HX has an unlocked multiplier. The socket types are different: the i5-14450HX uses Intel BGA 1964 (mobile), while the i7-14701E uses Intel Socket 1700 (desktop). The market segments confirm this: the i5-14450HX is a mobile processor, and the i7-14701E is a desktop processor.

The release dates differ by roughly six months. The i5-14450HX was released on 2024-01-07, and the i7-14701E on 2024-06-30. Both are listed as Active in production status.

The Verdict

The data points to a clear overall winner. The Intel Core i7-14701E wins 15 of 17 head-to-head benchmarks, including every Cinebench test and every PassMark test except data encryption and random string sorting. Its average benchmark score of 33206 sits above the 33201 average of the AMD Ryzen 9 PRO 6950H, its closest rival, and it ranks in the 83rd percentile. The Core i5-14450HX, with an average score of 32040, sits just below the Intel Core i7-13705H at 32076 and ranks in the 82nd percentile.

For users running multi-threaded productivity workloads such as rendering, video encoding, or scientific computing, the i7-14701E delivers a consistent 9.4% advantage across the Cinebench suite. For single-threaded tasks, the 15.4% lead in PassMark single-thread makes it the better choice for older games, legacy applications, and any software that scales poorly across cores. The 13 MB larger L3 cache and 0.60 GHz higher boost clock are the architectural foundations of this lead.

The Core i5-14450HX is only preferable in two narrow scenarios: data encryption workloads, where it leads by 4.8%, and random string sorting, where it leads by 1.4%. Users whose primary applications fall into those categories may see a small benefit from the i5-14450HX. For every other measured workload, the i7-14701E is the faster processor.

The desktop versus mobile distinction also matters for system design. The i7-14701E uses a desktop socket (Intel Socket 1700) and has a locked multiplier, while the i5-14450HX uses a mobile socket (Intel BGA 1964) and has an unlocked multiplier. The i5-14450HX is intended for laptops and mobile workstations, while the i7-14701E is for desktop builds. Given the benchmark results, the i7-14701E offers superior performance in the vast majority of tests, making it the stronger choice for desktop users who prioritize raw throughput and single-thread speed.
