Intel Core 7 350 vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive overall victory for the Intel Core i5-14450HX, which wins 13 of the 17 recorded comparisons. The largest margins occur in multi-threaded workloads, where the i5-14450HX delivers a 60.1% advantage in Cinebench R23 multi-core (20108 vs 8030) and a 56.9% lead in PassMark integer math (78330 vs 33734). Data compression shows a 48.6% gap (278538 vs 143123), while random string sorting trails by 41.7% (29565 vs 17238). These results indicate that the i5-14450HX is substantially stronger in tasks that scale with core count and thread count.

The Intel Core 7 350 wins the remaining 4 comparisons. Its clearest single-thread victory comes in PassMark single-thread, scoring 4100 against 3643, a 12.5% lead. In Cinebench R15 single-core, the Core 7 350 edges ahead by 2.5% (292 vs 285). The Core 7 350 also wins PassMark find prime numbers with a 9.2% margin (107 vs 98). These wins show that the Wildcat Lake part holds a genuine single-core advantage, even though the i5-14450HX takes the newer Cinebench R20 and R23 single-core tests by 36.4% and 27.9% respectively.

The Cinebench R20 single-core result deserves attention because it reverses the R15 outcome. The i5-14450HX scores 1191 versus 758, a 36.4% lead, which is a much larger margin than the Core 7 350's 2.5% win in R15. This suggests the i5-14450HX's single-core performance is not uniformly weaker, but rather workload dependent. The PassMark single-thread result favors the Core 7 350 by 12.5%, yet Cinebench R23 single-core favors the i5-14450HX by 27.9%. The data does not support a blanket statement that either chip is universally better for single-threaded work.

In multi-core Cinebench tests, the i5-14450HX consistently widens its lead as the workload becomes more demanding. The R15 multi-core margin is 39.8%, R20 is 36.4%, and R23 reaches 60.1%. The larger R23 gap indicates that sustained multi-threaded rendering favors the i5-14450HX more heavily than shorter tests. The Core 7 350's 6 cores and 6 threads cannot match the 10 cores and 16 threads of the i5-14450HX in these scenarios.

PassMark results reinforce the multi-thread gap. Floating point math favors the i5-14450HX by 26.2% (58037 vs 42809), multithread by 35.9% (23680 vs 15170), and physics by 20.5% (1475 vs 1173). Data encryption shows a 29.8% lead for the i5-14450HX (15574 vs 10933), and extended instructions trail by 30% (17207 vs 12045). The only PassMark test where the Core 7 350 leads is find prime numbers, which is a narrow workload and does not offset the broader pattern.

The average benchmark scores position the i5-14450HX at 32040, while the Core 7 350 sits at 17779. The i5-14450HX ranks in the 82nd percentile of all CPUs, compared to the 71st percentile for the Core 7 350. The nearest rivals for the Core 7 350 include the Intel Core 5 221TE with an average score of 17860 (0.5% higher), the AMD EPYC 9374F at 17693 (0.5% lower), the AMD Ryzen 5 3600XT at 17891 (0.6% higher), and the Intel Core 5 120U at 17898 (0.7% higher). The i5-14450HX sits near the Intel Core i7-13705H at 32076 (0.1% lower), the Intel Core i5-14400 at 32115 (0.2% lower), the Intel Core i7-12800H at 32121 (0.3% lower), and the Intel Core i9-11900 at 32226 (0.6% lower).

Where Each One Wins

The Intel Core 7 350 wins in specific single-threaded and lightweight integer workloads. Its 12.5% PassMark single-thread lead indicates responsiveness in programs that use one core heavily. The 2.5% Cinebench R15 single-core margin and 9.2% find prime numbers advantage point to a strong per-core design. For users running older legacy single-threaded applications or prime-number calculations, the Core 7 350 is the faster part.

The Intel Core i5-14450HX wins nearly everywhere else. Rendering, video encoding, data compression, encryption, physics simulation, and general multi-threaded productivity all favor the i5-14450HX by double-digit margins. The 60.1% Cinebench R23 multi-core lead and 56.9% integer math advantage make it the clear choice for content creation and compiled workloads. The 48.6% compression lead (278538 vs 143123) is particularly relevant for archiving and file transfer tasks. The 41.7% random string sorting lead (29565 vs 17238) suggests better performance in sorting-heavy data processing.

The single-core split is nuanced. The Core 7 350 wins PassMark single-thread and Cinebench R15 single-core, but the i5-14450HX wins Cinebench R20 single-core by 36.4% and Cinebench R23 single-core by 27.9%. The discrepancies between benchmark versions indicate that the i5-14450HX's single-core advantage appears in more recent Cinebench versions, possibly reflecting instruction set or architecture differences that newer tests utilize. The Core 7 350's wins are concentrated in older tests and PassMark's single-thread metric, which may not capture the same workload characteristics.

The i5-14450HX also holds a 20.5% lead in PassMark physics and a 35.9% lead in PassMark multithread. These results confirm that the i5-14450HX is better suited for simulation and parallel processing. The Core 7 350's 15 W TDP suggests it belongs in thinner, lighter systems, while the 55 W TDP of the i5-14450HX aligns with larger laptops designed for sustained performance.

Architecture Differences

The two processors come from different design families. The Intel Core 7 350 uses the Wildcat Lake codename on a 3 nm process node, while the Intel Core i5-14450HX uses the Raptor Lake-HX codename on a 10 nm process node. The Core 7 350 has 6 cores and 6 threads, whereas the i5-14450HX has 10 cores and 16 threads. The thread count difference is larger than the core count difference, indicating that the i5-14450HX uses hyper-threading while the Core 7 350 does not.

The Verdict

The data clearly favors the Intel Core i5-14450HX for most computing tasks. It wins 13 of 17 benchmarks, holds a 60.1% lead in Cinebench R23 multi-core, and ranks in the 82nd percentile of all CPUs. Its 10 cores, 16 threads, 20 MB L3 cache, and dual-channel memory support provide the structural advantages that explain its dominance in multi-threaded workloads. The i5-14450HX is the appropriate choice for rendering, data compression, encryption, physics, and any parallel processing task where the 55 W TDP can be accommodated.

The Intel Core 7 350 has a narrower but real set of strengths. Its 12.5% PassMark single-thread lead, 9.2% find prime numbers win, and 2.5% Cinebench R15 single-core win indicate that it can outperform the i5-14450HX in certain single-threaded and lightweight integer workloads. Its 15 W TDP and 3 nm process node suggest it is designed for power-constrained mobile systems. The Core 7 350 ranks in the 71st percentile overall, which is respectable but below the i5-14450HX.

Users who need maximum multi-core throughput should select the Intel Core i5-14450HX. Users who prioritize single-threaded performance in specific workloads, or who require the lower power envelope of the Core 7 350, have a narrower but valid case for that processor. The benchmark evidence does not support choosing the Core 7 350 for general productivity or content creation, as the i5-14450HX leads by double digits in nearly every such category.
