Intel Core i5-14401E vs Intel Core Ultra 5 245T Comparison

Head-to-Head Benchmarks

The benchmark data records six direct Cinebench comparisons between the Intel Core i5-14401E and the Intel Core Ultra 5 245T. The results are uniform: the Core Ultra 5 245T wins every single test. The margin is remarkably consistent, hovering around 30.7% in favor of the Ultra 5 across all six workloads.

In Cinebench R15 multicore, the Core i5-14401E scores 1830 against 2641 for the Core Ultra 5 245T, a 30.7% deficit. The single-core R15 test shows a similar story: 258 versus 372, also a 30.7% gap. The R20 multicore test records 7627 for the i5-14401E and 11007 for the Ultra 5 245T, again a 30.7% difference. In R20 single-core, the scores are 1076 and 1553 respectively, with the same percentage gap.

The R23 results follow the exact same pattern. The multicore test shows the i5-14401E at 18161 and the Ultra 5 245T at 26208, a 30.7% advantage. In R23 single-core, the i5-14401E scores 2564 while the Ultra 5 245T reaches 3699, also 30.7% higher. The consistency of this delta across both single and multi-threaded workloads indicates a broad architectural advantage rather than a workload-specific quirk.

The Core Ultra 5 245T also has additional Passmark results recorded in the database. Its data compression score is 283812, data encryption reaches 23656, extended instructions score 22071, and prime number finding hits 324. Floating point math achieves 108499, integer math 88676, and multithread performance 30833. Physics scores 2278, random string sorting 34931, and single-thread performance 4367. The i5-14401E has no corresponding Passmark entries in the database, so direct comparison across those workloads is not possible from the recorded data.

The percentile rankings reinforce the separation. The Core Ultra 5 245T sits at the 86th percentile of all CPUs in the database, while the Core i5-14401E sits at the 60th percentile. The average benchmark score for the Ultra 5 245T is 38194, versus 5253 for the i5-14401E. This substantial difference in average score reflects the fact that the Ultra 5's benchmark suite includes more varied workloads, but the Cinebench head-to-head data already establishes a clear performance hierarchy.

The Verdict

The recorded data points to the Intel Core Ultra 5 245T as the stronger processor in every measured category. It wins all six head-to-head Cinebench tests with a consistent 30.7% margin. Its 86th percentile ranking versus the 60th percentile of the Core i5-14401E places it firmly above its older counterpart in overall database positioning.

The Core Ultra 5 245T's nearest rivals in the database include the AMD Ryzen 7 250, which scores 38221 against the Ultra 5's 38194, a delta of -0.1%. The Intel Core i5-13600HX scores 38261, putting it 0.2% ahead of the Ultra 5. The Intel Core i5-14490F scores 38149, only 0.1% behind. The Core i5-13600KF scores 38103, 0.2% behind. These close margins indicate the Ultra 5 245T is positioned in a tightly contested performance band.

For the Core i5-14401E, its nearest rivals include the Intel Xeon E5-2699A v4 at 5259 average score, 0.1% above its own 5253. The Intel Core i7-11700B scores 5241, 0.2% below. The Intel Core i9-10850K also scores 5240, 0.2% below. The Intel Core i5-13400T scores 5210, 0.8% below. The i5-14401E thus sits in a lower performance tier where the competition is among older and lower-power desktop parts.

The data supports the Core Ultra 5 245T for workloads that benefit from higher Cinebench scores, both single and multi-threaded. The Core i5-14401E remains competitive within its own tier but does not close the gap in any measured test.

Architecture Differences

The two processors come from different Intel generations and use different manufacturing approaches. The Core i5-14401E belongs to the Core 14th Gen series, codename Raptor Lake-R, built on an Intel 10 nm process. The Core Ultra 5 245T belongs to Core Ultra Series 2, codename Arrow Lake-S, built on a TSMC 3 nm process. The process node difference is substantial: 3 nm versus 10 nm, which affects transistor density and power characteristics.

The transistor counts differ significantly. The Core Ultra 5 245T packs 17,800 million transistors on a 243 mm² die. The Core i5-14401E has no transistor count recorded in the database, but its die size is 215 mm². The smaller die with fewer recorded transistors on the i5 side, combined with the older process, explains much of the performance gap.

Core configuration differs as well. The Core i5-14401E has 6 cores and 12 threads, indicating hyper-threading support. The Core Ultra 5 245T has 14 cores and 14 threads, meaning no hyper-threading, but the higher physical core count drives its multicore advantage. The Ultra 5 also has higher cache capacities at every level: 192 KB L1 per core versus 80 KB, 3 MB L2 per core versus 1.25 MB, and 24 MB shared L3 versus 20 MB.

Clock speeds favor the Ultra 5 in boost terms. The Core i5-14401E runs at a 2.50 GHz base and 4.70 GHz boost. The Core Ultra 5 245T runs at a lower 2.20 GHz base but a higher 5.10 GHz boost. The higher boost clock contributes to its single-core performance lead, while the core count drives the multicore lead.

The memory support also differs. The Core i5-14401E supports both DDR4 and DDR5 memory on a dual-channel bus. The Core Ultra 5 245T supports only DDR5, also dual-channel, with a recorded memory bandwidth of 102.4 GB/s. The i5-14401E has no memory bandwidth figure recorded.

Both processors support ECC memory. The sockets differ: the i5-14401E uses Intel Socket 1700, while the Ultra 5 245T uses Intel Socket 1851. PCIe support also differs: the i5-14401E provides Gen 5 with 16 lanes (CPU only), while the Ultra 5 245T provides Gen 5 with 20 lanes (CPU only).

The integrated graphics differ as well. The Core i5-14401E uses UHD Graphics 730, while the Core Ultra 5 245T uses Arc Xe-LPG Graphics 64EU. The release dates are about six months apart, with the i5-14401E released on 2024-06-30 and the Ultra 5 245T on 2025-01-06. Neither processor has an unlocked multiplier.

Where Each One Wins

The Intel Core Ultra 5 245T wins in every head-to-head benchmark recorded in the database. All six Cinebench tests, including both single-core and multicore variants of R15, R20, and R23, show the Ultra 5 ahead by approximately 30.7%. This makes it the clear choice for rendering workloads, compilation tasks, and any application that scales with Cinebench-style multi-threaded performance. Its higher single-core scores also favor lightly threaded applications such as older games or single-threaded productivity tools.

The Core Ultra 5 245T also benefits from its higher boost clock of 5.10 GHz versus 4.70 GHz, which explains its single-core advantage. Its larger L3 cache of 24 MB versus 20 MB, plus larger per-core L1 and L2 caches, supports its performance in cache-sensitive workloads. The memory bandwidth of 102.4 GB/s, recorded only for the Ultra 5, may also contribute to its throughput advantage in memory-bound tasks.

The Core i5-14401E does not win any recorded benchmark against the Ultra 5. Its advantages are structural rather than performance-based. It supports DDR4 memory, which may be relevant for users with existing DDR4 platforms on Socket 1700. Its lower core count of 6 cores and 12 threads means lower thread scheduling complexity, and its older 10 nm Intel process may have different power characteristics, though no power measurements are recorded in the database. The i5-14401E also keeps a 65 W TDP, the same as the Ultra 5, despite the performance gap.

For users constrained to Socket 1700 platforms, the Core i5-14401E offers a functional path within the Core 14th Gen family. For users building on Socket 1851 with DDR5 memory, the Core Ultra 5 245T is the stronger option based on the recorded data. The Ultra 5's 86th percentile ranking versus the 60th percentile of the i5-14401E places it in a different competitive class, closer to the AMD Ryzen 7 250 and the Core i5-13600HX in average score.
