Intel Core i5-14400T vs Intel Core i5-14401E Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the Intel Core i5-14401E across every Cinebench test in the head-to-head comparison. The i5-14401E wins all six benchmark comparisons, with the i5-14400T trailing by a consistent margin of roughly 5.3 to 5.4 percent in each test. In Cinebench R15 multicore, the i5-14401E scores 1830 against the i5-14400T’s 1732, a delta of -5.4 percent for the T-model. The single-core R15 test shows the same pattern: 258 versus 244, again a 5.4 percent deficit for the i5-14400T.

Moving to Cinebench R20, the i5-14401E delivers 7627 in multicore compared to 7219 for the i5-14400T, a 5.3 percent gap. Single-core R20 results are 1076 versus 1018, with the i5-14400T again 5.4 percent behind. The largest absolute difference appears in Cinebench R23 multicore, where the i5-14401E reaches 18161 and the i5-14400T sits at 17189, a 972-point gap that represents the same 5.4 percent margin. In R23 single-core, the i5-14401E posts 2564 against 2426, keeping the pattern intact.

The consistency of these deltas is striking. Every single-core test shows exactly 5.4 percent separation, and the multicore deltas vary only from 5.3 to 5.4 percent. This uniformity suggests the performance gap is driven by a fundamental architectural difference rather than workload-specific behavior. The i5-14401E’s higher base clock of 2.50 GHz versus 1.50 GHz on the i5-14400T likely explains much of this advantage, especially in single-threaded tasks where boost behavior matters less over sustained periods.

The broader database context reinforces this picture. The i5-14400T carries an average benchmark score of 27166 and ranks in the 79th percentile among all CPUs, while the i5-14401E has an average benchmark score of only 5253 and sits in the 60th percentile. That apparent contradiction, the i5-14401E winning every head-to-head test yet having a far lower average score, stems from the fact that the i5-14401E’s benchmark set is limited to six Cinebench runs, whereas the i5-14400T includes extensive PassMark tests. The i5-14400T’s nearest rivals include the Intel Core i9-9900K (delta 0.3 percent) and AMD Ryzen 7 5700G (delta 0.4 percent), placing it in strong company. The i5-14401E’s nearest rivals are the Intel Xeon E5-2699A v4 (delta -0.1 percent) and Intel Core i7-11700B (delta 0.2 percent), a very different competitive tier.

Architecture Differences

Both processors share the same fundamental architecture: Raptor Lake, specifically Raptor Lake-R, built on Intel’s 10 nm process node with a 215 mm² die size. They use the same Intel Socket 1700, support DDR4 and DDR5 memory in dual-channel configuration, include UHD Graphics 730 integrated graphics, and both accept ECC memory. The cache hierarchy is identical on paper: 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache.

The critical difference lies in core configuration. The i5-14400T has 10 cores and 16 threads, while the i5-14401E has 6 cores and 12 threads. This 4-core, 4-thread advantage for the i5-14400T would ordinarily suggest superior multicore throughput, yet the benchmark data shows the opposite: the i5-14401E wins multicore tests consistently. The explanation centers on clock speeds. The i5-14401E has a base clock of 2.50 GHz and a boost clock of 4.70 GHz, while the i5-14400T operates at 1.50 GHz base and 4.50 GHz boost. The i5-14401E’s base clock is 66.7 percent higher, a massive gap that allows its six performance-oriented cores to sustain higher throughput even with fewer total cores.

Thermal design power also diverges significantly. The i5-14400T is rated at 35 watts TDP, while the i5-14401E carries a 65 watt TDP. This near-doubling of power budget for the E-variant enables the higher clock speeds and explains why the T-model, designed for low-power efficiency, sacrifices raw performance. The i5-14400T’s 35 watt envelope makes it a low-heat option, but the benchmark results confirm that this efficiency comes at a measurable performance cost.

The release dates differ as well. The i5-14400T launched on 2024-01-07, while the i5-14401E arrived later on 2024-06-30. The i5-14400T carries a launch MSRP of $221, while the i5-14401E has no recorded launch price in the database. Both processors are currently marked as Active in production status, and neither has an unlocked multiplier. The part numbers differ: SRN3N for the i5-14400T and Q49JSRNJS for the i5-14401E.

The Verdict

The benchmark data presents a clear hierarchy: the Intel Core i5-14401E outperforms the Intel Core i5-14400T in every recorded Cinebench test, with a consistent 5.3 to 5.4 percent margin. The i5-14401E’s higher base and boost clocks, enabled by a 65 watt TDP, prove decisive even though it has 4 fewer cores and 4 fewer threads. The i5-14400T’s 35 watt TDP and lower clocks cap its performance, but its 10-core, 16-thread configuration and extensive PassMark results place it in a higher overall CPU percentile (79th versus 60th).

The i5-14401E’s nearest rivals in the database include the Intel Core i7-11700B and Intel Core i9-10850K, both within 0.2 percent of its average score. The i5-14400T sits alongside the Intel Core i9-9900K and AMD Ryzen 7 5700G, with deltas of 0.3 and 0.4 percent respectively. This means the i5-14400T competes in a higher performance tier based on its average score, despite losing head-to-head against the i5-14401E. The discrepancy arises because the i5-14400T’s PassMark suite, which includes data compression (235636), integer math (65667), and floating point math (49139), contributes to a much larger average score.

For workloads heavily weighted toward Cinebench-style rendering, the i5-14401E is the stronger choice based on the recorded data. Its 4.70 GHz boost clock and 2.50 GHz base clock deliver measurable wins in both single and multicore scenarios. The i5-14400T remains viable for users prioritizing lower power consumption, but the performance trade-off is a uniform 5.4 percent in favor of the i5-14401E.

Where Each One Wins

The i5-14401E wins in every single-threaded and multithreaded Cinebench scenario recorded. Its advantages are most pronounced in sustained multicore workloads where the higher base clock prevents frequency drop-off, as evidenced by the R23 multicore score of 18161 against 17189. The 5.4 percent single-core advantage also extends to lightly threaded tasks, where the 4.70 GHz boost clock outpaces the i5-14400T’s 4.50 GHz ceiling.

The i5-14400T does not win any of the six head-to-head tests, but it holds advantages outside those benchmarks. Its 10-core, 16-thread configuration provides greater parallel capacity for workloads that scale beyond what six cores can handle, though the database does not include tests demonstrating this. Its 35 watt TDP makes it a lower-power option, and its launch MSRP of $221 provides a recorded price point, whereas the i5-14401E has no launch MSRP in the database. The i5-14400T also has a broader benchmark footprint, with PassMark scores covering data compression, encryption, prime number finding, floating point math, integer math, multithread performance, physics, random string sorting, and single-thread performance. The i5-14401E only has Cinebench scores, so its performance in those other categories remains unmeasured.

In practice, the i5-14401E suits users who need maximum Cinebench-class rendering performance and can accommodate a 65 watt TDP. The i5-14400T appeals to those who value the lower 35 watt power envelope, the higher core count for non-benchmarked parallel tasks, and the established $221 launch price. The data does not indicate any scenario where the i5-14400T beats the i5-14401E in the tested workloads, but its specification profile suggests it may handle different workload types more gracefully, particularly those that benefit from additional cores beyond six.
