Intel Core 7 251E vs Intel Core i5-14400F Comparison

Intel Core 7 251E vs Intel Core i5-14400F

Head-to-Head Benchmarks

The database contains a complete benchmark record for the Intel Core i5-14400F, but no recorded measurements for the Intel Core 7 251E. As a result, the head-to-head comparison is one-sided, with the Core i5-14400F holding all available benchmark scores. The Core 7 251E has an average benchmark score of zero, while the Core i5-14400F posts an average of 32,279 points.

The Core i5-14400F delivers strong multi-threaded results. In Cinebench R23, it scores 21,645 points in the multi-core test and 3,055 points in the single-core test. Its Cinebench R20 results show 9,090 for multi-core and 1,283 for single-core, while the older Cinebench R15 test returns 2,181 multi-core and 307 single-core. Geekbench records 11,268 for multi-core and 2,058 for single-core.

The Passmark suite provides additional detail. The Core i5-14400F scores 25,470 in the multithread test and 3,701 in the single-thread test. Integer math reaches 81,524, floating-point math hits 61,319, and extended instructions score 19,937. Data encryption completes at 16,949, while data compression finishes at 315,521. Random string sorting records 32,680, physics processing scores 1,523, and finding prime numbers returns 86.

These numbers place the Core i5-14400F at the 83rd percentile among all CPUs in the database. Its nearest rivals provide context for this ranking. The AMD Ryzen 7 PRO 8840U scores 32,233, which is 0.1% behind. The Intel Core i9-11900 scores 32,226, also 0.2% behind. The AMD Ryzen 7 6800HS scores 32,354, placing it 0.2% ahead. The Intel Core i7-12800H scores 32,121, putting it 0.5% behind. The Core i5-14400F sits effectively in the middle of this group, with only the Ryzen 7 6800HS edge ahead.

With no benchmark scores recorded for the Core 7 251E, the data cannot confirm any performance advantage for that processor. The Core i5-14400F stands as the only measured option in this pairing, and its results indicate a capable desktop processor that competes directly with upper-mid-range mobile and older desktop chips.

The Verdict

The recorded data points clearly toward the Intel Core i5-14400F for anyone requiring measured performance. Its 83rd percentile ranking and average benchmark score of 32,279 confirm that it delivers solid results across both single-threaded and multi-threaded workloads. The Core 7 251E, by contrast, has no benchmark entries in the database, so its performance cannot be quantified or compared.

The Core i5-14400F belongs to the Core 14th Gen series, uses the Raptor Lake architecture, and carries the Raptor Lake-R codename. It was released earlier, and its production status remains active. The Core 7 251E uses the Bartlett Lake codename and falls under the Core 7 generation. Both processors target the desktop market segment, both use Intel Socket 1700, and both have a 65 W TDP. Neither has an unlocked multiplier.

For a builder who needs a processor with verified results, the Core i5-14400F is the only choice supported by data. Its benchmark scores show a processor that handles multi-threaded rendering, encryption, and math workloads without difficulty. The Core 7 251E may offer more cores and threads, but without measurements, that specification advantage cannot be translated into actual performance.

Where Each One Wins

The Core i5-14400F wins in every measurable category because it is the only processor in this comparison with recorded benchmark data. Its multi-core Cinebench R23 score of 21,645 indicates strong performance in rendering and content creation workloads. The single-core score of 3,055 shows fast response in lightly threaded tasks. The Passmark multithread score of 25,470 confirms that the 10 cores and 16 threads work effectively under parallel load.

The data encryption score of 16,949 and data compression score of 315,521 suggest the Core i5-14400F handles file archiving and security-related tasks efficiently. The floating-point math score of 61,319 and integer math score of 81,524 point to solid number-crunching ability for scientific or engineering applications. The physics score of 1,523 indicates reasonable performance in simulation workloads.

The Core 7 251E cannot claim any benchmark win because the database contains no scores for it. Its specification sheet lists 24 cores and 32 threads, which suggests potential in heavily threaded scenarios, but the absence of measurements means no performance conclusion can be drawn. Similarly, its 5.60 GHz boost clock is higher than the Core i5-14400F's 4.70 GHz, but without test results, that clock advantage remains theoretical.
