Intel Core 7 251E vs Intel Core i5-14401TE Comparison

The Intel Core 7 251E and Intel Core i5-14401TE are both active Intel desktop processors for the Intel Socket 1700 platform, but the specification records place them far apart in core count, thread count, cache, and power target. The Core 7 251E is a 24-core, 32-thread Bartlett Lake part with a 5.60 GHz boost clock and a 65 W TDP. The Core i5-14401TE is a 6-core, 12-thread Raptor Lake-R part with a 4.50 GHz boost clock and a 45 W TDP. The database contains no comparative benchmark scores for this pairing, so the analysis below is grounded in the recorded specifications and the 50th percentile all-CPU ranking attached to both records.

Architecture Differences

Both processors are built on Intel's 10 nm process and fabricated by Intel, and both use the Intel Socket 1700 package. The underlying designs differ, however. The Core 7 251E belongs to the Core 7 (Bartlett Lake) generation, while the i5-14401TE belongs to the Core 14th Gen family with Raptor Lake architecture and the Raptor Lake-R codename. The Core 7 251E's die is recorded at 257 mm², compared with 215 mm² for the i5-14401TE.

The core layout is the most visible architectural split. The Core 7 251E implements 24 cores and 32 threads, while the i5-14401TE implements 6 cores and 12 threads. Cache organization also differs: the Core 7 251E uses 2 MB of L2 per core and 36 MB of shared L3, whereas the i5-14401TE uses 1.25 MB of L2 per core and 20 MB of shared L3. Both use an 80 KB per-core L1 cache. The integrated graphics block differs as well, with UHD Graphics 770 on the Core 7 251E and UHD Graphics 730 on the i5-14401TE.

The two records share several platform-level features. Both processors support DDR4 and DDR5 memory, a dual-channel memory bus, ECC memory, and PCIe Gen 5 with 16 CPU lanes. Both are desktop parts, both are active in the database, and both have locked multipliers. The series field is another distinction: the i5-14401TE is listed under Core 14th Gen, while the Core 7 251E has no series entry. The part numbers also differ: SRQDUQ657 for the Core 7 251E and Q4T4SRNJP for the i5-14401TE.

Where Each One Wins

Using only the recorded specifications, the Core 7 251E holds the performance-oriented advantages. It has 24 cores to the i5-14401TE's 6, 32 threads to 12, a 5.60 GHz boost clock to 4.50 GHz, 36 MB of shared L3 to 20 MB, 2 MB per-core L2 to 1.25 MB, and 89.6 GB/s memory bandwidth to no listed figure for the i5-14401TE. The Core 7 251E also uses UHD Graphics 770, a higher-tier integrated graphics part than the UHD Graphics 730 in the i5-14401TE. For workloads that scale with core count, thread count, cache capacity, or integrated graphics capability, the specification advantage belongs to the Core 7 251E.

The i5-14401TE counters with a lower power target. Its TDP is 45 W, while the Core 7 251E is rated at 65 W. The i5-14401TE also has a smaller die at 215 mm², versus 257 mm² for the Core 7 251E. In a comparison based strictly on the recorded data, the i5-14401TE is the lower-power, smaller-die option, while the Core 7 251E dominates the raw compute specification sheet. The i5-14401TE also has an earlier release date, 2024-06-30, compared with 2025-01-12 for the Core 7 251E.

Head-to-Head Benchmarks

The database records no head-to-head benchmark scores for the Core 7 251E versus the Core i5-14401TE. Neither processor has a wins entry in this pairing, and neither has a benchmark score attached to its record. Both carry a 50th percentile against all CPUs and a 0 average benchmark score, but those values do not establish a performance order because there are no measured results behind them. Therefore, there are no exact benchmark deltas to report. The only quantitative comparison available comes from the specification table above: core count, thread count, clocks, cache, TDP, memory bandwidth, die size, and integrated graphics.

Because no benchmark data exists for this specific pairing, any claim of a measured performance winner would go beyond the record. The 50th percentile ranking is identical for both parts, so it does not separate them. The 0 average benchmark score is also identical and reflects the absence of attached benchmark entries rather than a measured result. The specification differences remain the only recorded basis for comparing these two processors.

The Verdict

From the recorded data, the Core 7 251E is the part to select for any workload definition that prioritizes maximum core count, thread count, cache, memory bandwidth, or integrated graphics. It offers 24 cores, 32 threads, a 5.60 GHz boost clock, 36 MB of shared L3, 2 MB per-core L2, 89.6 GB/s memory bandwidth, and UHD Graphics 770. The i5-14401TE is the part to select when the priority is a lower TDP of 45 W against 65 W and a smaller die size of 215 mm² against 257 mm². It offers 6 cores, 12 threads, a 4.50 GHz boost clock, 20 MB of shared L3, 1.25 MB per-core L2, and UHD Graphics 730.

There is no benchmark evidence in the database to override those specification-level conclusions. The Core 7 251E is the newer release, with a 2025-01-12 date, while the i5-14401TE has a 2024-06-30 date. The Core 7 251E is the higher-core, higher-thread, higher-cache part. The i5-14401TE is the lower-power, smaller-die part. The data points to the Core 7 251E for compute-heavy desktop use and to the i5-14401TE for configurations where a 45 W TDP is the defining constraint.
