Architecture Differences

The two processors come from different architectural lineages within Intel's desktop lineup. The Intel Core 7 251E is based on the Bartlett Lake codename, part of the Core 7 generation, while the Intel Core i5-14401E uses the Raptor Lake-R codename and belongs to the Core 14th Gen series, specifically the Raptor Lake Refresh generation.

Both chips are fabricated on Intel's 10 nm process node and use the same Intel Socket 1700 platform. The die sizes differ notably: the Core 7 251E measures 257 mm², while the Core i5-14401E is smaller at 215 mm². This size difference reflects the substantially larger core count on the Core 7 251E, which packs 24 cores into its silicon, four times the six cores found on the Core i5-14401E.

The core configuration yields a thread disparity as well. The Core 7 251E supports 32 threads from its 24 cores, while the Core i5-14401E supports 12 threads from its six cores. This suggests a high-core-count design on the Bartlett Lake part, likely with a mix of performance and efficiency cores, although the database does not specify the exact core type breakdown.

Cache hierarchies diverge sharply. Both use 80 KB of L1 cache per core, but the L2 allocation differs: the Core 7 251E provides 2 MB per core, whereas the Core i5-14401E provides 1.25 MB per core. The shared L3 cache on the Core 7 251E is 36 MB, nearly double the 20 MB on the Core i5-14401E. These cache differences compound the core-count advantage, giving the Core 7 251E significantly more on-die storage for working sets.

Both processors support DDR4 and DDR5 memory across a dual-channel bus, and both enable ECC memory, which suits workstation or reliability-focused builds. PCIe connectivity is identical on paper: Gen 5 with 16 lanes from the CPU. Integrated graphics differ, with the Core 7 251E carrying UHD Graphics 770 and the Core i5-14401E using the lower-tier UHD Graphics 730.

The Core 7 251E launched on 2025-01-12 and carries a launch MSRP of $384. The Core i5-14401E released earlier on 2024-06-30, with no launch MSRP recorded in the database. Both parts remain in active production, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains benchmark results for the Intel Core i5-14401E across six Cinebench tests, but no benchmark scores are recorded for the Intel Core 7 251E. The head-to-head comparison table is empty, meaning direct measurement-based wins cannot be attributed to either processor in this dataset.

The Core i5-14401E's recorded scores establish a performance baseline. In Cinebench R15, it scores 1830 in multi-core and 258 in single-core. Cinebench R20 shows 7627 multi-core and 1076 single-core. Cinebench R23 delivers 18161 multi-core and 2564 single-core. These numbers place the chip at the 60th percentile of all CPUs, with an average benchmark score of 5253.

The nearest rivals for the Core i5-14401E provide context for its standing. The Intel Xeon E5-2699A v4 scores 5259, which is 0.1% higher than the Core i5-14401E's average. The Intel Core i7-11700B scores 5241, 0.2% lower. The Intel Core i9-10850K also scores 5240, 0.2% lower. The Intel Core i5-13400T scores 5210, 0.8% lower. This cluster of rivals sits within a narrow 49-point spread, indicating that the Core i5-14401E performs at a level comparable to several established desktop and workstation parts from previous generations.

The Core 7 251E, by contrast, has a percentile rank of 50 and an average benchmark score of 0, reflecting the absence of recorded test data. Without Cinebench scores for the Core 7 251E, the database offers no direct numerical comparison of rendering performance, single-thread speed, or multi-thread throughput between the two chips. The only quantitative signals available are the architectural specifications: the Core 7 251E's higher core count, larger caches, and higher boost clock all suggest potential advantages in multi-threaded workloads, but the recorded data does not confirm this with measured scores.

The wins tally remains zero for both processors in the head-to-head field. This means no benchmark category in the database shows one chip beating the other, simply because the Core 7 251E has no entries to compare against.

Fields that match include the manufacturer (Intel), TDP (65 W for both), socket (Intel Socket 1700), process node (10 nm), foundry (Intel), L1 cache (80 KB per core), memory support (DDR4 and DDR5), memory bus (dual-channel), ECC support (true for both), PCIe configuration (Gen 5, 16 lanes CPU-only), market segment (Desktop), production status (Active), and multiplier unlock status (false for both).

The Verdict

The data presents a split picture. The Intel Core 7 251E offers a dramatically larger core and thread count, with 24 cores and 32 threads against 6 cores and 12 threads on the Intel Core i5-14401E. Its L3 cache is 16 MB larger, its per-core L2 cache is 0.75 MB larger, and its boost clock runs 0.90 GHz higher. These specifications point to a processor built for heavily parallel workloads, such as rendering, compilation, or server-style tasks, where additional cores translate directly into throughput. The 89.6 GB/s memory bandwidth figure on the Core 7 251E further supports a high-throughput profile.

The Intel Core i5-14401E counters with a higher base clock (2.50 GHz versus 2.10 GHz) and a substantial body of measured benchmark data. Its Cinebench R23 multi-core score of 18161 and single-core score of 2564 demonstrate solid performance in a mainstream desktop context. Its average benchmark score of 5253 places it at the 60th percentile, and its nearest rivals, the Xeon E5-2699A v4, Core i7-11700B, Core i9-10850K, and Core i5-13400T, all fall within 0.8% of its average score, confirming that it performs in line with established mid-range and high-end parts from prior generations.

The Core 7 251E has no recorded benchmarks, so its real-world performance cannot be verified from the database. Its 50th percentile rank and average score of 0 reflect missing measurements rather than poor results. Any claim that the Core 7 251E outperforms the Core i5-14401E must rest on its specifications alone, not on tested outcomes.

For users selecting between these two parts, the Core i5-14401E is the only option with verified performance data. Its 60th percentile standing and competitive scores against well-known rivals give it a documented baseline. The Core 7 251E, with its quadruple core count, larger caches, and higher boost clock, appears positioned for workloads that scale with core availability, but the database does not yet contain the measurements to confirm that expectation. The choice hinges on whether the user trusts the architectural advantages of the Core 7 251E or requires the confirmed benchmark results of the Core i5-14401E.
