The i5-14450HX does not win a single recorded benchmark, making the choice straightforward for any user prioritizing raw compute performance.

Architecture Differences

The two processors share Intel's 10 nm process node and both are built by Intel, but their underlying designs diverge significantly. The Core 7 253PE uses the Bartlett Lake codename and is listed under the "Core 7 (Bartlett Lake)" generation, while the i5-14450HX belongs to the Raptor Lake-HX Refresh family with the Raptor Lake architecture. The Core 7 operates on Intel Socket 1700 as a desktop part, whereas the i5-14450HX uses Intel BGA 1964 and targets the mobile segment.

Core and thread counts reveal a key difference: both have 10 physical cores, but the Core 7 253PE supports 20 threads through hyperthreading, while the i5-14450HX manages only 16 threads. The cache hierarchy also differs in the shared L3 portion: the Core 7 253PE has 33 MB of shared L3 cache, while the i5-14450HX has 20 MB. Per-core L1 and L2 caches are identical at 80 KB and 2 MB per core, respectively.

Clock speeds favor the Core 7 253PE, with a base clock of 2.50 GHz and boost clock of 5.50 GHz, compared to the i5's 2.40 GHz base and 4.80 GHz boost. The thermal design point also differs: 65 W for the Core 7 versus 55 W for the i5. The Core 7 253PE is a locked multiplier (multiplierUnlocked: false), while the i5-14450HX has an unlocked multiplier, allowing overclocking on the mobile part.

Integrated graphics differ as well: the Core 7 253PE carries UHD Graphics 730, while the i5-14450HX uses UHD Graphics 710. Memory support is identical at DDR4 and DDR5 with dual-channel bus, but the Core 7 253PE records a memory bandwidth of 89.6 GB/s, while the i5-14450HX has no recorded bandwidth figure. Both support ECC memory and PCIe Gen 5 with 16 lanes from the CPU.

Head-to-Head Benchmarks

The Core 7 253PE dominates across every recorded workload. In Cinebench R23, the multi-core score reaches 24880 against 20108 for the i5-14450HX, a 23.7% advantage. Single-core in R23 shows 3512 versus 2838, also 23.7% ahead. The pattern holds for R20: multi-core 10449 versus 8445 (23.7% delta) and single-core 1475 versus 1191 (23.8% delta). In R15, the multi-core result is 2507 against 2026 (23.7%), and single-core 354 versus 285 (24.2%).

PassMark tests reveal even larger margins in some compute-heavy operations. Integer math produces the biggest gap: 114158 for the Core 7 versus 78330 for the i5, a 45.7% advantage. Floating-point math follows with 80870 versus 58037, or 39.3% higher. Prime number finding shows a 40.8% delta (138 versus 98), and extended instructions land at 26.7% (21806 versus 17207). Data compression scores 339133 versus 278538 (21.8%), while data encryption reaches 18385 versus 15574 (18%).

The multi-threaded PassMark score is 29271 versus 23680, a 23.6% delta, and the physics test shows 1845 versus 1475, or 25.1% higher. Random string sorting is the closest passmark result at 10.9% (32777 versus 29565), and the single-thread PassMark score delivers 3955 versus 3643, an 8.6% edge. The smallest relative advantage appears in the single-threaded test, suggesting the Core 7's higher boost clock contributes but the larger L3 cache and extra threads drive the multi-core wins.

Where Each One Wins

The Intel Core 7 253PE wins in every recorded benchmark category. Its most decisive victories are in PassMark integer math (45.7% ahead), floating-point math (39.3% ahead), and prime number finding (40.8% ahead). These results indicate a substantial advantage in arithmetic-heavy compute workloads, likely driven by the higher boost clock of 5.50 GHz and the larger 33 MB L3 cache. The Core 7 also leads in extended instructions by 26.7%, making it suited for workloads that exercise SIMD or specialized instruction sets.

The i5-14450HX, despite losing all head-to-head tests, retains a few distinct attributes. Its unlocked multiplier allows manual overclocking, which could narrow the gap in single-threaded tasks if the user tunes it aggressively. The 55 W TDP is lower than the Core 7's 65 W, potentially making it more suitable for constrained thermal environments in mobile chassis. The i5 also has a recorded die size of 257 mm², though no such figure exists for the Core 7. However, based strictly on the recorded data, the Core 7 253PE delivers superior performance in every measured workload, with the smallest delta still at 8.6% in single-thread PassMark.

For users selecting between these two, the Core 7 253PE is the choice for multi-threaded rendering, data compression, encryption, and math-heavy simulation. The i5-14450HX offers overclocking flexibility and a lower TDP, but the benchmark evidence shows no workload category where it outperforms the Core 7. The 87th percentile ranking for the Core 7 versus 82nd for the i5 reinforces the overall standing in the database.
