Architecture Differences

The two processors represent different generations and design philosophies. The Core i5-14401TE uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, and is part of the Core 14th Gen family. It is built on a 10 nm process at Intel's own foundry. The Core Ultra 5 250K Plus belongs to the Core Ultra Series 2, codenamed Arrow Lake Refresh, and is manufactured by TSMC on a 3 nm process. This process difference is significant, as the Ultra chip integrates 17,800 million transistors on a 243 mm² die, while the i5-14401TE has a smaller 215 mm² die.

The core configurations differ sharply. The i5-14401TE is a 6-core, 12-thread part, indicating hyper-threading support. The Ultra 5 250K Plus provides 18 cores and 18 threads, meaning it relies on a larger physical core count without simultaneous multi-threading. The Ultra chip also has a substantially higher base clock (4.20 GHz vs 2.00 GHz) and boost clock (5.30 GHz vs 4.50 GHz).

Cache hierarchies are structured differently. The i5-14401TE has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. The Ultra 5 250K Plus has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. The larger per-core caches on the Ultra part reflect its newer design.

Memory support diverges as well. The i5-14401TE supports both DDR4 and DDR5 with a dual-channel bus, while the Ultra 5 250K Plus supports only DDR5 but with a measured memory bandwidth of 115.2 GB/s. Both processors support ECC memory. The PCIe configurations also differ: the i5-14401TE provides Gen 5 with 16 CPU lanes, while the Ultra 5 250K Plus provides Gen 5 with 20 CPU lanes.

Integrated graphics are different. The i5-14401TE uses UHD Graphics 730, while the Ultra 5 250K Plus uses Arc Xe-LPG Graphics with 64 execution units. The socket types are incompatible: the i5-14401TE uses Intel Socket 1700, and the Ultra 5 250K Plus uses Intel Socket 1851.

The multiplier is locked on the i5-14401TE, while the Ultra 5 250K Plus has an unlocked multiplier. The power envelope differs, with the i5-14401TE rated at 45W TDP and the Ultra 5 250K Plus rated at 125W TDP. The Ultra part also has a later release date of 2026-03-10, compared to the i5-14401TE's release on 2024-06-30.

The Verdict

The benchmark data clearly favors the Intel Core Ultra 5 250K Plus. The Ultra chip has a 93rd percentile ranking among all CPUs, while the i5-14401TE sits at the 50th percentile. The average benchmark score for the Ultra 5 250K Plus is 66,855, whereas the i5-14401TE has no recorded benchmark scores in the database, making any direct comparison impossible on that metric.

The Ultra 5 250K Plus delivers strong multi-core performance, as shown by its Cinebench R23 multi-core score of 30,867 and its PassMark multi-thread score of 51,596. Its single-core results are also solid, with a Cinebench R23 single-core score of 2,261 and a PassMark single-thread score of 4,757. The i5-14401TE has no benchmark entries, so the database cannot confirm any performance level for that chip.

In terms of nearest rivals, the Ultra 5 250K Plus sits within 1% of several comparable processors. It trails the AMD EPYC 4465P by 0.1%, the Intel Xeon 6515P by 0.2%, and the Intel Core Ultra 9 275HX by 0.9%. It leads the Intel Core Ultra 5 250KF Plus by 1.1%. This positions the Ultra 5 250K Plus as competitive with high-end server and laptop parts.

For workloads requiring many cores, high memory bandwidth, and newer architecture, the Ultra 5 250K Plus is the recommended choice based on the data. The i5-14401TE, with its lower TDP and support for DDR4, might be suited for legacy systems or power-constrained builds, but the database lacks benchmark evidence to support any performance claims for it.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark comparisons between the Core i5-14401TE and the Core Ultra 5 250K Plus. The i5-14401TE has an empty benchmark list and zero recorded wins. The Ultra 5 250K Plus has a comprehensive set of benchmark results, but there are no direct pairwise measurements against the i5-14401TE.

The Ultra 5 250K Plus, however, has extensive standalone results. In Cinebench R15, it scores 4,640 in multi-core and 328 in single-core. In Cinebench R20, the scores are 18,442 multi-core and 2,603 single-core. In Cinebench R23, the multi-core score is 30,867 and the single-core score is 2,261.

PassMark results for the Ultra 5 250K Plus include data compression at 568,721, data encryption at 42,144, extended instructions at 44,565, and prime number finding at 486. Floating point math scores 162,692, integer math scores 125,091, and multithread scores 51,596. Physics scores 3,494, random string sorting scores 69,090, and single-thread performance is 4,757.

Since the i5-14401TE has no recorded benchmarks, the data cannot establish any performance delta between the two processors. The only comparative context comes from the Ultra 5 250K Plus's nearest rivals, which show it within a narrow band of other high-end CPUs. The i5-14401TE's 50th percentile ranking suggests it sits in the middle of the database's CPU distribution, but without benchmark scores, that ranking cannot be translated into specific workload performance.

Where Each One Wins

The Core Ultra 5 250K Plus wins in every measurable performance category, based on the available data. Its 18 cores and 18 threads, combined with a 5.30 GHz boost clock, make it suited for multi-threaded workloads such as rendering, encoding, and scientific computation. The Cinebench R23 multi-core score of 30,867 and the PassMark multithread score of 51,596 confirm strong parallel performance. The 115.2 GB/s memory bandwidth supports data-intensive applications.

The Ultra 5 250K Plus also wins on single-thread performance, with a Cinebench R23 single-core score of 2,261 and a PassMark single-thread score of 4,757. Its newer 3 nm process and larger caches contribute to higher clock speeds and better per-core efficiency. The unlocked multiplier allows tuning for overclocking, and the Arc Xe-LPG integrated graphics provide a more modern GPU solution.

The Core i5-14401TE has no benchmark wins recorded in the database. Its advantages are structural rather than performance-based. The 45W TDP makes it a lower-power part, and its support for DDR4 memory allows integration into systems with older memory modules. The Intel Socket 1700 compatibility may be relevant for existing platform upgrades. The i5-14401TE's 6 cores and 12 threads are sufficient for lighter workloads, but the database lacks any measurements to quantify that capability.

The data suggests that the Ultra 5 250K Plus is the stronger processor for nearly all scenarios, especially those requiring high core counts and modern features. The i5-14401TE could serve in power-sensitive or legacy-compatible builds, but there is no benchmark evidence in the database to support specific performance claims for it.
