Intel Core 7 253PQE vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The recorded data presents a remarkably one-sided comparison. Across all 17 shared benchmark tests, the Intel Core 7 253PQE records a win over the Intel Core i5-14400. The margins, however, vary significantly depending on the workload type, which reveals distinct performance characteristics.

The most dramatic separation appears in the PassMark physics test. The Core 7 253PQE scores 2970 against 1396 for the i5-14400, a delta of 112.8%. This nearly doubles the output, indicating a substantial advantage in workloads that stress physical simulation and game engine logic. Similarly, the prime number finding test shows a 157.5% delta, with scores of 206 versus 80. That is the largest relative gap in the entire dataset, suggesting a major edge in integer-heavy, latency-sensitive single-thread tasks.

Integer math performance follows the same pattern. The Core 7 253PQE delivers 137795 in PassMark integer math compared to 82017, a 68% advantage. Floating point math shows a 71% delta, with 105279 versus 61549. The extended instructions test, which often reflects SIMD and multimedia workload efficiency, shows a 63.5% delta favoring the Core 7 253PQE.

Multithreaded throughput also leans heavily toward the newer part. PassMark multithread scores 41656 versus 25080, a 66.1% delta. The Cinebench suite confirms this trend across every version tested. In Cinebench R23 multicore, the Core 7 253PQE scores 31390 against 21315, a 47.3% delta. The R20 multicore test shows 13183 versus 8952, also 47.3%. R15 multicore records 3163 versus 2148, again 47.3%. The consistency of this exact percentage across all three Cinebench versions is striking.

Single-core performance tells a slightly different story. The Cinebench single-core tests all show a 47.3% delta, with R23 scoring 4431 versus 3009, R20 scoring 1861 versus 1263, and R15 scoring 446 versus 303. However, the PassMark single-thread test shows a much narrower gap of 17.3%, with 4389 versus 3741. This discrepancy between Cinebench and PassMark single-thread results is noteworthy. It implies that the Core 7 253PQE gains from certain architectural efficiencies that Cinebench exploits more aggressively than PassMark does.

Data compression and encryption workloads also favor the Core 7 253PQE heavily. Compression scores 487335 versus 314995, a 54.7% delta. Encryption scores 25515 versus 16731, a 52.5% delta. Random string sorting shows a 67.6% delta, with 54222 versus 32346.

The average benchmark score reinforces the overall picture. The Core 7 253PQE sits at 55919, while the i5-14400 sits at 32115. The Core 7 253PQE ranks in the 91st percentile among all CPUs in the database, whereas the i5-14400 ranks in the 82nd percentile. The nearest rival cluster for the Core 7 253PQE includes the Intel Core i9-14900HX at 56004 (-0.2%), the AMD Ryzen AI Max 390 at 56273 (-0.6%), and the AMD Ryzen AI 9 HX PRO 470 at 56306 (-0.7%). The i5-14400, by contrast, sits near the Intel Core i7-12800H, the Intel Core i7-13705H, and the Intel Core i5-14450HX, all within 0.2% of its average score.

Where Each One Wins

The Core 7 253PQE wins every recorded benchmark, so the question becomes not whether it wins, but which workloads benefit most from its margin. The largest deltas cluster in physics simulation (112.8%), prime number computation (157.5%), and floating point math (71%). These are the workloads where the Core 7 253PQE separates itself most dramatically. The data suggests that applications relying on high-frequency integer loops, physics engines, and heavy arithmetic operations will see the greatest relative improvement.

The i5-14400 has no benchmark wins in this dataset. Its closest relative performance appears in the PassMark single-thread test, where the delta shrinks to 17.3%. Even there, it loses, but the smaller margin indicates that the i5-14400 retains competitive single-threaded responsiveness for lighter tasks. The Cinebench single-core tests, however, contradict that impression with a 47.3% delta. The discrepancy likely stems from the different instruction mixes and threading behavior each benchmark exercises.

For everyday desktop responsiveness, the PassMark single-thread result at 4389 versus 3741 suggests the i5-14400 remains usable, but the Core 7 253PQE still holds a clear edge. For heavily threaded rendering, compilation, or scientific workloads, the 47.3% to 66.1% deltas across Cinebench multicore and PassMark multithread make the Core 7 253PQE the obvious choice from a pure performance standpoint.

Architecture Differences

The two processors share the same Intel Socket 1700 and the same 10 nm process node, manufactured by Intel. Both support DDR4 and DDR5 memory over a dual-channel bus, and both provide PCIe Gen 5 with 16 CPU lanes. Both also support ECC memory and have locked multipliers.

The core and thread configuration differs significantly. The Core 7 253PQE has 10 cores and 20 threads, while the i5-14400 has 10 cores and 16 threads. That extra four threads indicates a different hybrid arrangement. The Core 7 253PQE belongs to the Bartlett Lake generation and codename, while the i5-14400 belongs to the Core 14th Gen series with the Raptor Lake-R codename and Raptor Lake architecture. The Core 7 253PQE generation is listed simply as "Core 7 (Bartlett Lake)", the i5-14400 as "Core i5 (Raptor Lake Refresh)".

Clock speeds show a substantial gap. The Core 7 253PQE has a base clock of 3.50 GHz and a boost clock of 5.70 GHz. The i5-14400 has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The 1.0 GHz difference in boost clock directly contributes to the single-thread deltas observed in the benchmarks.

Cache hierarchies differ as well. Both share an L1 cache of 80 KB per core. The L2 cache, however, is 2 MB per core on the Core 7 253PQE versus 1.25 MB per core on the i5-14400. The L3 cache is 33 MB shared on the Core 7 253PQE versus 20 MB shared on the i5-14400. The larger L3 allocation likely helps the Core 7 253PQE in the data compression and encryption tests, where working sets can exceed smaller cache capacities.

The integrated graphics differ. The Core 7 253PQE uses UHD Graphics 770, the i5-14400 uses UHD Graphics 730. The Core 7 253PQE also reports a memory bandwidth figure of 89.6 GB/s, while the i5-14400 has no recorded memory bandwidth value. The die size for the i5-14400 is 215 mm², but the Core 7 253PQE has no recorded die size. The release dates differ by over two years, with the i5-14400 launching on 2024-01-07 and the Core 7 253PQE on 2026-03-08.

The Verdict

The data points in one direction. The Intel Core 7 253PQE outperforms the Intel Core i5-14400 in every recorded benchmark, with deltas ranging from 17.3% in PassMark single-thread to 157.5% in prime number computation. The average benchmark score favors the Core 7 253PQE by a wide margin, 55919 versus 32115, and the percentile ranking confirms its placement in the 91st percentile versus 82nd for the i5-14400.

The i5-14400 retains relevance through its lower TDP of 65 watts versus 125 watts, its earlier release date, and its support for the same socket and memory types. For users prioritizing power efficiency or working within a more constrained platform budget, the i5-14400 remains a functional desktop processor. Its nearest rivals in the database include the Intel Core i7-12800H and the Intel Core i7-13705H, placing it in a mid-range performance tier.

The Core 7 253PQE, by contrast, positions itself near the Intel Core i9-14900HX and AMD Ryzen AI Max 390 in average score, with deltas under 1%. Its higher clock speeds, larger caches, and additional threads explain the benchmark outcomes. The data suggests that for users who prioritize maximum multi-threaded throughput, physics simulation, or heavy arithmetic workloads, the Core 7 253PQE delivers a decisive advantage. For users who prioritize lower power draw or earlier availability, the i5-14400 offers a more modest but still functional profile. The recorded measurements leave little ambiguity about which processor is faster, but the choice between them depends on whether raw performance or power efficiency matters more in the intended use case.
