Intel Core 7 251E vs Intel Core i7-14701E Comparison

Head-to-Head Benchmarks

The Intel Core 7 251E and Intel Core i7-14701E share a socket and TDP, but their recorded benchmark histories diverge sharply. The database contains a full Cinebench and PassMark suite for the i7-14701E, while the Core 7 251E has no benchmark entries at all. This asymmetry means the head-to-head comparison is one-sided: the i7-14701E carries all measured scores, and the Core 7 251E can only be assessed through its architectural specifications.

Focusing on the i7-14701E's recorded results, its Cinebench R23 multi-core score of 22195 places it in a strong position for heavily threaded workloads. Its single-core R23 result of 3133 indicates a per-thread capability that outpaces many desktop and mobile parts. In Cinebench R20, the multi-core score drops to 9321, and the single-core score is 1315, following the expected scaling pattern across benchmark revisions. The R15 suite shows 2237 multi-core and 315 single-core, again consistent with the older test's lighter load.

PassMark results for the i7-14701E reveal where its architecture excels. The integer math score of 81325 and floating point math score of 61873 show strong arithmetic throughput. Data compression reaches 282939, while data encryption scores 14862. The extended instructions score of 18528 and random string sorting at 29158 round out the general-purpose workload picture. Its single-thread PassMark score of 4305 and multithread score of 26112 both appear twice in the database, confirming stability across repeated runs. The find prime numbers test returns a modest 176, and physics simulation scores 2399.

Because the Core 7 251E lacks any benchmark scores, the database cannot compute a win tally for either processor. The head-to-head benchmark section therefore relies on comparing the i7-14701E's measured performance to its nearest rivals, all of which are listed with average scores near its own. The AMD Ryzen 9 PRO 6950H averages 33201, a delta of 0% against the i7-14701E's average of 33206. The AMD Ryzen 5 8645HS averages 33244, which is 0.1% higher, meaning the i7-14701E trails that part by a hair. The AMD Ryzen 7 7745HX averages 33091, or 0.3% lower, and the Intel Core i7-13650HX averages 33089, or 0.4% lower. These narrow deltas place the i7-14701E in a tight cluster where no single rival dominates by more than a fraction of a percent.

The Core 7 251E's percentile ranking of 50 against all CPUs is notably lower than the i7-14701E's 83rd percentile. This is not a measured performance gap; it reflects the absence of benchmark data for the Core 7 251E, which the database records as having an average benchmark score of zero. The i7-14701E's average benchmark score of 33206 and its 83rd percentile show that among all CPUs in the database, it sits comfortably in the upper quintile. The Core 7 251E's 50th percentile is a placeholder, not a performance verdict.

The Verdict

The recorded data supports a clear but incomplete conclusion. The i7-14701E has a full benchmark suite and a 83rd percentile ranking among all CPUs, with an average benchmark score of 33206. Its nearest rivals sit within 0.4% of its average score, placing it in a tightly contested performance band. The Core 7 251E has no benchmarks, a zero average score, and a 50th percentile ranking that is not derived from any measured workload.

For workloads that appear in the database, the i7-14701E shows strong multi-threaded and single-threaded results. Its Cinebench R23 multi-core score of 22195 and PassMark multithread score of 26112 indicate a capable desktop processor for rendering and parallel tasks. Its single-core Cinebench R23 score of 3133 and PassMark single-thread score of 4305 show competitive per-thread performance.

The Core 7 251E cannot be judged on measured performance. Its specifications suggest a different design philosophy: 24 cores, 32 threads, a lower base clock, a higher boost clock, and 3 MB more L3 cache. But without benchmark scores, any performance claim would be speculative. The database records no wins for either processor in head-to-head testing because no head-to-head benchmark data exists.

Users choosing between these two should rely on the i7-14701E's measured results and the Core 7 251E's architectural specifications. The i7-14701E offers verified performance data across multiple test suites. The Core 7 251E offers a higher core count, a higher boost clock, and a later release date, but no empirical evidence of performance in the database.

Where Each One Wins

The i7-14701E wins in every category where benchmark results exist. Its Cinebench and PassMark scores cover multi-core rendering, single-core responsiveness, integer and floating point math, data compression, encryption, extended instructions, prime number finding, random string sorting, physics simulation, and multithreaded throughput. In each of these tests, the database records a positive score, giving the i7-14701E a measured advantage over the Core 7 251E, which has no scores in any category.

The Core 7 251E wins on raw specifications. It has more cores, more threads, more L3 cache, a higher boost clock, and a recorded memory bandwidth figure. Its launch date is later, and it has a defined launch MSRP. For scenarios where core count and maximum frequency matter more than verified benchmark data, the Core 7 251E presents a stronger specification sheet.

The i7-14701E also wins on database standing. Its 83rd percentile versus the Core 7 251E's 50th percentile, and its average benchmark score of 33206 versus zero, both favor the i7-14701E in any comparison that uses recorded metrics. The nearest rival data shows the i7-14701E trading fractions of a percent with AMD Ryzen parts and an Intel HX-series chip, confirming it sits in a competitive performance class.

For users who prioritize measured performance, the i7-14701E is the only choice with data backing it. For users who prioritize specifications alone, the Core 7 251E offers a larger core cluster, a faster boost ceiling, and more L3, but no evidence of how those specs translate into actual workload results. The database cannot assign a win to either processor in a head-to-head sense because no head-to-head benchmarks were recorded. The i7-14701E wins by default on every measured metric, while the Core 7 251E wins only on paper.
