Intel Core 7 251TE vs Intel Core i3-14100T Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive margin favoring the Intel Core 7 251TE across every recorded test. The Core 7 251TE wins all 17 head-to-head comparisons, while the Intel Core i3-14100T records zero victories. The scale of the advantage varies significantly by workload, from a narrow 2% edge in single-threaded PassMark tests to a 212.1% lead in integer math.

In Cinebench tests, the Core 7 251TE consistently outperforms the i3-14100T by approximately 119.8%. The Cinebench R23 multi-core score of 25518 versus 11612 shows the larger processor more than doubling the output of the i3-14100T. Single-core Cinebench results tell a similar story, with the Core 7 251TE scoring 3602 against the i3-14100T's 1639, a 119.8% difference. This pattern repeats in Cinebench R15 and R20, where single-core and multi-core deltas all hover near the same 119.7% to 119.8% range.

PassMark results reveal where the Core 7 251TE extends its advantage furthest. The integer math test shows the largest gap, with the Core 7 251TE scoring 125739 versus 40292, a 212.1% delta. Data encryption follows closely at 181.4% (22176 versus 7881), and floating point math shows a 172.8% lead (85607 versus 31379). Random string sorting also demonstrates a wide margin at 154.5% (39643 versus 15579), while prime number finding shows a 150% delta (140 versus 56).

The narrowest margins appear in single-threaded workloads. PassMark single-thread performance puts the Core 7 251TE at 3568 and the i3-14100T at 3498, a difference of only 2%. This suggests that for purely single-threaded instruction streams, the two processors are nearly equivalent despite the Core 7 251TE's higher boost clock. The extended instructions test shows a 63% delta (16974 versus 10414), which is the second-smallest gap recorded but still a substantial win for the Core 7 251TE.

The physics test shows a 99.2% delta (1938 versus 973), and the PassMark multi-thread score of 30022 versus 13662 represents a 119.7% lead. Data compression follows the same trend at 119.1% (334399 versus 152636). Across all 17 tests, the Core 7 251TE's average benchmark score of 41650 places it in the 88th percentile of all CPUs, while the i3-14100T's average of 17648 sits in the 71st percentile.

Where Each One Wins

Given that the Core 7 251TE wins every head-to-head benchmark in the database, the use-case split is defined by the relative size of the margins rather than by which processor takes a given category. The Core 7 251TE dominates heavily in multi-threaded and parallel workloads. Cinebench multi-core scores, PassMark multi-thread, integer math, floating point math, encryption, compression, and random string sorting all show deltas of at least 119.1%. These workloads benefit directly from the Core 7 251TE's 24 cores and 32 threads, which allow far more simultaneous instruction streams than the i3-14100T's 4 cores and 8 threads.

The i3-14100T's strongest relative showing is in single-threaded PassMark tests, where the 2% delta makes the two processors nearly interchangeable. The i3-14100T also comes closest in extended instructions, where the 63% gap is the smallest of any test category. These results indicate that the i3-14100T can hold its own in lightly threaded tasks, but the data does not show any recorded workload where it actually surpasses the Core 7 251TE.

The Core 7 251TE's nearest rivals in the database include the Intel Core Ultra 7 265H at a 0.1% delta, the Intel Core i7-14650HX at 0.2%, and the Intel Core i7-12850HX at -0.3%. The i3-14100T's nearest rivals include the Intel Core i3-13100F at a 0% delta, the Intel Core i7-1255U at 0%, and the AMD Ryzen 3 8300GE at 0.2%. These reference points confirm that the Core 7 251TE competes in a much higher performance tier than the i3-14100T, which sits alongside lower-core-count desktop and mobile parts.

Architecture Differences

The two processors share the same Intel Socket 1700, the same 10 nm process node, and the same Intel foundry. Both support DDR4 and DDR5 memory over a dual-channel bus, and both have ECC memory support. PCIe connectivity is identical at Gen 5 with 16 lanes from the CPU. Neither processor has an unlocked multiplier.

The core configuration differs substantially. The Core 7 251TE uses 24 cores and 32 threads, while the i3-14100T uses 4 cores and 8 threads. Base clocks also differ, with the Core 7 251TE running at 1.40 GHz and the i3-14100T at 2.70 GHz. Boost clocks reverse this relationship, as the Core 7 251TE reaches 5.40 GHz versus the i3-14100T's 4.40 GHz. The thermal design power differs, with the Core 7 251TE rated at 45 watts and the i3-14100T at 35 watts.

Cache allocation shows several divergences. Both processors have 80 KB of L1 cache per core and 1.25 MB of L2 cache per core. The L3 cache, however, is much larger on the Core 7 251TE at 36 MB shared, compared to 12 MB shared on the i3-14100T. The die size also differs, with the Core 7 251TE at 215 mm² and the i3-14100T at 163 mm².

The integrated graphics differ as well. The Core 7 251TE includes UHD Graphics 770, while the i3-14100T includes UHD Graphics 730. The Core 7 251TE uses the Bartlett Lake codename with a Core 7 (Bartlett Lake) generation designation, while the i3-14100T uses the Raptor Lake-R codename with a Core i3 (Raptor Lake Refresh) generation designation. The i3-14100T also carries the "Core 14th Gen" series label.

Release dates place the i3-14100T earlier, with a launch date in January 2024, while the Core 7 251TE launched in January 2025. The production status for both is listed as active. The Core 7 251TE has a launch MSRP of $384, while the i3-14100T has a launch MSRP of $134.

The Verdict

The recorded data points to a clear performance hierarchy. The Core 7 251TE holds a commanding lead in every benchmark in the database. Its average benchmark score of 41650 is roughly 2.36 times the i3-14100T's 17648. The Core 7 251TE ranks in the 88th percentile of all CPUs, while the i3-14100T ranks in the 71st percentile.

For multi-threaded rendering, data compression, encryption, and heavy mathematical workloads, the Core 7 251TE is the only choice based on the numbers. Margins exceeding 100% in Cinebench multi-core tests and PassMark multi-thread tests indicate that this processor can complete such tasks in less than half the time of the i3-14100T. The 24-core, 32-thread configuration provides the parallel headroom that the i3-14100T's 4-core, 8-thread design lacks.

For single-threaded tasks, the gap narrows to 2%, meaning the i3-14100T is competitive in that specific category. The i3-14100T's higher base clock of 2.70 GHz partially compensates for the Core 7 251TE's lower 1.40 GHz base clock, though the Core 7 251TE's 5.40 GHz boost clock still gives it the edge in the recorded PassMark single-thread scores.

The i3-14100T suits a user whose workloads are primarily single-threaded and who wants a smaller, lower-power package. The 35 watt TDP and 4-core layout make it a lighter option for basic desktop tasks. The Core 7 251TE suits a user who needs maximum multi-threaded throughput, as evidenced by its 88th percentile ranking and its position alongside rivals like the Intel Core Ultra 7 265H and Intel Core i7-14650HX, both of which sit within 0.2% of its average score.
