Architecture Differences

The two processors diverge significantly in their core configurations. The Intel Core 7 251TE packs 24 cores and 32 threads, while the Intel Core i7-14701E uses 8 cores and 16 threads. This threefold core difference explains most of the multicore benchmark gaps. Both chips share the Intel Socket 1700, the 10 nm process node, and Intel as the foundry, but their underlying designs differ.

The Core 7 251TE belongs to the Bartlett Lake family, while the i7-14701E uses the Raptor Lake architecture with the Raptor Lake-R codename and a Core 14th Gen series designation. The Core 7 251TE carries the generation label "Core 7 (Bartlett Lake)," while the i7-14701E is labeled "Core i7 (Raptor Lake Refresh)." Die size differs as well: the Core 7 251TE measures 215 mm², while the i7-14701E is larger at 257 mm² despite having fewer cores.

Cache hierarchies show meaningful differences. Both processors share the same L1 cache at 80 KB per core. The L2 cache, however, favors the i7-14701E at 2 MB per core versus 1.25 MB per core for the Core 7 251TE. The L3 cache is shared and slightly larger on the Core 7 251TE at 36 MB, compared to 33 MB on the i7-14701E.

Memory support is identical on paper: both support DDR4 and DDR5, use dual-channel memory buses, and support ECC memory. The Core 7 251TE lists a memory bandwidth of 89.6 GB/s, while the i7-14701E does not have a recorded bandwidth figure. PCIe connectivity matches at Gen 5 with 16 lanes from the CPU. Both integrate UHD Graphics 770.

Clock speeds present an interesting contrast. The base clock on the i7-14701E is 2.60 GHz, notably higher than the 1.40 GHz base on the Core 7 251TE. The boost clocks are identical at 5.40 GHz. The i7-14701E also carries a higher TDP of 65 watts versus 45 watts for the Core 7 251TE, reflecting its higher base frequency and larger die. Neither processor has an unlocked multiplier.

Release timing differs by roughly six months. The i7-14701E launched on 2024-06-30, while the Core 7 251TE followed on 2025-01-12. Both remain in active production. The Core 7 251TE has a recorded launch MSRP of $384, while no launch MSRP exists for the i7-14701E in the database.

The Verdict

The benchmark data indicates that the Intel Core 7 251TE is the stronger overall processor for most workloads. Its 24-core, 32-thread configuration delivers decisive advantages in rendering, encryption, compression, and math-intensive tasks. The 15% edge across all Cinebench tests, the 54.6% lead in integer math, and the 49.2% lead in data encryption all point to a processor built for sustained multi-threaded throughput. The 88th percentile ranking among all CPUs, compared to the 83rd percentile for the i7-14701E, confirms its higher standing in the database.

The Intel Core i7-14701E, however, demonstrates superior per-core efficiency in specific scenarios. Its 17.1% single-thread lead and 19.2% physics advantage show that its 2 MB per-core L2 cache and higher base clock contribute to stronger latency-sensitive performance. The 20.5% edge in prime number finding and 8.4% lead in extended instructions further indicate that certain integer-heavy or specialized instruction workloads respond better to the i7-14701E's design.

The data suggests that the Core 7 251TE is the appropriate choice for workloads that scale with core count and thread count. The i7-14701E is preferable where single-thread responsiveness or specific instruction patterns matter more than raw throughput. The identical boost clocks and shared socket compatibility mean both processors fit the same platform, but their performance profiles diverge sharply based on workload characteristics.
