Intel Core 7 251E vs Intel Core i5-14600 Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear and decisive winner in aggregate performance: the Intel Core i5-14600. The database records the Core i5-14600 with an average benchmark score of 44,889, placing it at the 89th percentile among all CPUs. The Intel Core 7 251E, by contrast, holds the 50th percentile with an average score of zero recorded in the database, indicating insufficient or unavailable performance measurements for direct comparison.

The Core i5-14600 delivers a substantial multi-core performance advantage. In Cinebench R23 multi-core, the Core i5-14600 scores 30,464 points. In Cinebench R20 multi-core, it scores 12,794 points, and in Cinebench R15 multi-core, it scores 3,070 points. The single-core results are equally notable: 4,300 in Cinebench R23 single-core, 1,806 in Cinebench R20 single-core, and 433 in Cinebench R15 single-core. Geekbench results show 14,680 multi-core and 2,424 single-core scores.

PassMark tests further illustrate the Core i5-14600's strengths. The multi-thread score is 35,848, with single-thread at 4,167. Data compression scores 434,620, data encryption scores 25,082, and extended instructions score 25,674. Floating-point math reaches 85,759, integer math reaches 117,078, physics scores 2,330, and random string sorting scores 48,043.

The Core 7 251E has 24 cores and 32 threads, which is 10 more cores and 12 more threads than the Core i5-14600's 14 cores and 20 threads. However, the database contains no benchmark scores for the Core 7 251E, so the measured performance data cannot confirm whether this core count translates into any practical advantage. The Core i5-14600's higher clock speeds (2.70 GHz base and 5.20 GHz boost) versus the Core 7 251E's 2.10 GHz base and 5.60 GHz boost suggest the i5 starts from a higher baseline, though the 251E has a 0.40 GHz higher boost ceiling.

The nearest rivals for the Core i5-14600 provide context for its performance tier. The Intel Core i9-12900KS scores 45,094, which is 0.5% lower than the Core i5-14600. The AMD EPYC 4344P scores 45,122, also 0.5% lower. The AMD Ryzen 5 7500X3D scores 44,573, which is 0.7% higher than the Core i5-14600, and the Intel Core Ultra X9 388H scores 44,466, 1% higher. These small deltas indicate the Core i5-14600 sits in a tightly contested performance band where rival chips are within one percentage point of its average score.

The Verdict

The data points firmly toward the Intel Core i5-14600 as the superior performer for any workload that relies on measured compute throughput. Its benchmark scores span every major test category, and its 89th percentile ranking versus the Core 7 251E's 50th percentile shows a wide gap in recorded performance. The Core 7 251E lacks any benchmark entries in the database, meaning there is no quantitative evidence to support its selection for performance-sensitive tasks.

The Core i5-14600's nearest rival comparisons reinforce its standing. It effectively trades blows with the Core i9-12900KS, the AMD EPYC 4344P, the AMD Ryzen 5 7500X3D, and the Core Ultra X9 388H, all within a 1% margin. This places the Core i5-14600 in elite company, delivering performance comparable to flagship-class processors from both Intel and AMD.

Users who require a processor with confirmed high multi-threaded throughput should select the Core i5-14600. The data shows it excels in Cinebench multi-core workloads, PassMark multi-thread tests, and Geekbench multi-core tests. The Core 7 251E, with its larger core count, remains an unquantified option; without benchmark data, it cannot be recommended for any specific workload based on measured results.

Architecture Differences

The Intel Core 7 251E uses the Bartlett Lake codename, while the Intel Core i5-14600 uses Raptor Lake-R from the Raptor Lake architecture. Both processors are built on a 10 nm process node at Intel's foundry, and both have a die size of 257 mm². The Core 7 251E belongs to the Core 7 (Bartlett Lake) generation, whereas the Core i5-14600 belongs to the Core i5 (Raptor Lake Refresh) generation.

Where Each One Wins

The Intel Core i5-14600 wins in every measured category because it is the only one of the two with recorded benchmark data. Its Cinebench R23 multi-core score of 30,464 and single-core score of 4,300 establish strong performance in rendering and single-threaded tasks. The Geekbench multi-core score of 14,680 and single-core score of 2,424 indicate solid general-purpose compute. PassMark results show particular strengths in integer math (117,078), floating-point math (85,759), and data compression (434,620), which point to productivity and scientific workloads.

The Core 7 251E wins on paper specifications: more cores (24 versus 14), more threads (32 versus 20), higher boost clock (5.60 GHz versus 5.20 GHz), larger L3 cache (36 MB versus 24 MB), and a higher recorded memory bandwidth (89.6 GB/s). These specifications suggest potential advantages in heavily parallel workloads, but the database contains no benchmark results to verify this. The 251E also has a newer release date (2025 versus 2024) and a higher launch MSRP ($384 versus $255).

For any workload where performance is determined by measured benchmarks, the Core i5-14600 is the clear choice. The data shows it delivers top-tier results across all available tests, matching or beating rivals like the Core i9-12900KS and AMD EPYC 4344P within a 1% margin. The Core 7 251E remains an unverified option; its higher core count and larger cache could theoretically benefit multithreaded applications, but without benchmark evidence, those advantages remain speculative. Users who need confirmed performance should rely on the Core i5-14600's recorded scores.
