Intel Core 7 253PE vs Intel Core i5-14400F Comparison

Head-to-Head Benchmarks

The recorded data shows a comprehensive victory for the Intel Core 7 253PE across all 17 shared benchmark comparisons. The Core i5-14400F does not secure a single win in any measured test. The most decisive margin appears in the PassMark find prime numbers test, where the Core 7 253PE scores 138 against 86 for the Core i5-14400F, a 60.5% advantage. This is the largest percentage gap in the entire head-to-head set.

The integer math workload also shows a substantial difference. The Core 7 253PE delivers 114158 in PassMark integer math, while the Core i5-14400F manages 81524, placing the Core 7 253PE 40% ahead. Floating point math follows a similar pattern: 80870 versus 61319, a 31.9% lead for the Core 7 253PE. These math-heavy results point to a meaningful throughput advantage in compute-dense tasks.

Cinebench results are consistent across all three versions of the render test. In Cinebench R23 multi-core, the Core 7 253PE scores 24880 against 21645 for the Core i5-14400F, a 14.9% edge. Single-core performance in the same test shows the Core 7 253PE at 3512 versus 3055, a 15% gain. The R20 and R15 iterations mirror this pattern: 10449 versus 9090 in R20 multi-core and 2507 versus 2181 in R15 multi-core, both with deltas of roughly 15%. Single-core R20 results show 1475 versus 1283, and R15 single-core shows 354 versus 307, with deltas of 15% and 15.3%, respectively.

PassMark multithread performance also favors the Core 7 253PE by 14.9%, with scores of 29271 and 25470. The physics workload shows a 21.1% difference, with the Core 7 253PE scoring 1845 and the Core i5-14400F scoring 1523.

The narrower wins are worth attention as well. PassMark data compression shows 339133 for the Core 7 253PE against 315521, a 7.5% margin. Data encryption lands at 18385 versus 16949, an 8.5% difference. Extended instructions score 21806 versus 19937, a 9.4% edge. Single-thread performance in PassMark is tighter: 3955 versus 3701, a 6.9% advantage. The closest result of all is random string sorting, where the Core 7 253PE scores 32777 and the Core i5-14400F scores 32680, a mere 0.3% difference.

The average benchmark score reinforces the overall picture. The Core 7 253PE posts an average of 40557 across its benchmark suite, while the Core i5-14400F averages 32279. The percentile ranking also confirms the separation: the Core 7 253PE sits at the 87th percentile of all CPUs, while the Core i5-14400F sits at the 83rd.

Where Each One Wins

The Core 7 253PE wins every measured category, but the size of the advantage varies by workload type. The largest gains come from integer math, floating point math, and prime number finding, suggesting workloads that rely heavily on arithmetic throughput benefit the most. The 40% lead in integer math and the 31.9% lead in floating point math indicate that the Core 7 253PE handles computation-heavy tasks with a clear performance buffer.

The Prime number workload is particularly telling. A 60.5% advantage there implies a strong per-core execution advantage in this specific calculation pattern. The Core i5-14400F trails badly in this test, scoring 86 versus 138.

Render workloads tell a slightly different story. The Cinebench suite shows consistent 15% advantages across all versions, which suggests that multi-threaded render performance is improved but not to the same degree as pure math workloads. The physics test shows a 21.1% edge, slotting between the math results and the Cinebench results.

Memory and I/O adjacent workloads show the smallest gaps. Data compression, data encryption, and extended instructions all land in the 7.5% to 9.4% range. Random string sorting is the closest test at 0.3%, indicating that this particular workload barely distinguishes the two processors.

The single-threaded PassMark result shows a 6.9% advantage for the Core 7 253PE, while Cinebench single-core tests show a much larger 15% gap. This discrepancy suggests that the two suites stress different aspects of single-core performance, with Cinebench being more sensitive to the architectural differences between the two chips.

Architecture Differences

Both processors use a 10 nm process node from Intel and both fit the Intel Socket 1700. The Core 7 253PE belongs to the Bartlett Lake codename family, while the Core i5-14400F uses the Raptor Lake-R codename and the Raptor Lake architecture.

The Verdict

The benchmark data makes the hierarchy clear. The Intel Core 7 253PE outperforms the Intel Core i5-14400F in every single recorded test, with no exceptions. The average benchmark score difference is substantial: 40557 for the Core 7 253PE versus 32279 for the Core i5-14400F. The percentile placement also favors the Core 7 253PE, which sits at the 87th percentile of all CPUs compared to the 83rd for the Core i5-14400F.

The nearest rival data provides context for each chip's standing. The Core 7 253PE sits within 0.3% of the Intel Core 5 223PE, the Intel Core Ultra X7 368H, the Intel Xeon 6357P, and the AMD Ryzen 9 7940H, all clustered around the 40431 to 40630 average score range. The Core i5-14400F likewise sits close to its rivals, including the AMD Ryzen 7 PRO 8840U, Intel Core i9-11900, AMD Ryzen 7 6800HS, and Intel Core i7-12800H, all within 0.5% of its 32279 average.

The choice between these two processors depends on the workload priority. For compute-heavy tasks such as integer math, floating point math, and prime number calculations, the Core 7 253PE offers a decisive advantage, with margins ranging from 31.9% to 60.5%. For render workloads, the advantage is a consistent 15% across Cinebench versions. For memory-oriented tasks like data compression and random string sorting, the gap narrows to between 0.3% and 9.4%.

The Core 7 253PE also brings integrated graphics, which the Core i5-14400F lacks entirely. Systems built around the Core i5-14400F require a discrete GPU for any display output. The Core 7 253PE can function with its UHD Graphics 730 in configurations where a separate graphics card is not needed.

The thread count difference of 20 versus 16 explains part of the multi-threaded performance gap, while the higher boost clock of 5.50 GHz versus 4.70 GHz supports the single-threaded advantages. The larger caches, 33 MB L3 versus 20 MB L3 and 2 MB per core L2 versus 1.25 MB per core L2, also contribute to the recorded performance differences.

Both processors share the same TDP of 65 W, the same socket, the same process node, and the same dual-channel DDR4/DDR5 memory support. The Core 7 253PE is the newer part with a March 2026 release date, while the Core i5-14400F dates to January 2024. The launch MSRP of the Core 7 253PE is $384.

For users prioritizing raw compute throughput, the Core 7 253PE is the stronger choice across every benchmark category. For users with lighter workloads where the Core i5-14400F's smaller margins in memory-oriented tasks are acceptable, the older part remains a functional desktop processor, but the data does not show any category where it exceeds the Core 7 253PE.
