Intel Core i5-14401TE vs Intel Core Ultra 7 255H Comparison

Where Each One Wins

The benchmark data splits cleanly along workload type. The Intel Core Ultra 7 255H wins in every recorded test category, and the Intel Core i5-14401TE has no recorded benchmark scores to claim any victory. The Ultra 7 255H's dominance spans single-threaded, multi-threaded, and specialized instruction workloads.

In single-core performance, the Ultra 7 255H posts a Cinebench R23 single-core score of 1843, a Geekbench single-core score of 2335, and a PassMark single-thread score of 4317. These numbers place it in the 83rd percentile among all CPUs in the database. The i5-14401TE sits at the 50th percentile with no recorded benchmarks, meaning the database contains no direct measurements for comparison.

Multi-threaded workloads show the widest gap. The Ultra 7 255H delivers a Cinebench R23 multi-core score of 9240, a Geekbench multi-core score of 14024, and a PassMark multithread score of 30703. The i5-14401TE has no entries for any of these tests. The Ultra 7 255H's nearest rivals in the database include the AMD Ryzen 5 240 with a 0% delta, the AMD Ryzen 7 8840HS and AMD Ryzen 5 7645HX both at -0.4%, and the Intel Core i5-12600HX at +0.5%. This cluster indicates the Ultra 7 255H performs in line with a tight group of mid-range mobile processors.

Specialized workloads further favor the Ultra 7 255H. PassMark data compression scores 298850, data encryption scores 23395, extended instructions score 23755, floating point math scores 98796, integer math scores 77975, physics scores 2254, and random string sorting scores 36058. The find prime numbers test returns 303. None of these tests have corresponding entries for the i5-14401TE.

The verdict for use-case selection is straightforward: the Ultra 7 255H is the only part with measurable performance data, and it wins every category where data exists. The i5-14401TE cannot be recommended for any workload based on recorded benchmarks, as the database contains zero measurements for it.

Architecture Differences

The two processors come from different Intel generations and use different foundries and process nodes. The i5-14401TE belongs to the Core 14th Gen series, uses Raptor Lake architecture (codename Raptor Lake-R), and is fabricated on a 10 nm process at Intel's own foundry. The Ultra 7 255H belongs to the Core Ultra Series 2, uses Arrow Lake architecture (codename Arrow Lake-H), and is fabricated on a 3 nm process at TSMC.

The core and thread counts differ substantially. The i5-14401TE has 6 cores and 12 threads, while the Ultra 7 255H has 16 cores and 16 threads. The Ultra 7 255H doubles the core count and adds 4 threads over the i5-14401TE. Thread counts equal core counts on the Ultra 7 255H, indicating no Hyper-Threading for its efficiency cores, while the i5-14401TE maintains a 2:1 thread-to-core ratio.

Cache hierarchies differ at every level. The i5-14401TE has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The Ultra 7 255H has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The Ultra 7 255H more than doubles the per-core L1 and L2 allocations and adds 4 MB to the shared L3 pool.

Clock speeds show a modest boost advantage for the Ultra 7 255H. Both parts have a 2.00 GHz base clock. The i5-14401TE boosts to 4.50 GHz, while the Ultra 7 255H boosts to 5.10 GHz. The Ultra 7 255H also carries a lower TDP of 28 watts versus 45 watts for the i5-14401TE, despite having more cores and a higher boost clock.

Memory support diverges. The i5-14401TE supports DDR4 and DDR5 memory, while the Ultra 7 255H supports DDR5 and LPDDR5X. The Ultra 7 255H has a recorded memory bandwidth of 102.4 GB/s; the i5-14401TE has no bandwidth figure in the database. Both are dual-channel and support ECC memory.

The socket and form factor differ completely. The i5-14401TE uses Intel Socket 1700 and is a desktop part. The Ultra 7 255H uses Intel BGA 2049 and is a mobile part. PCIe lanes also differ: the i5-14401TE provides Gen 5 with 16 lanes, while the Ultra 7 255H provides Gen 5 with 20 lanes. Integrated graphics differ as well, with UHD Graphics 730 on the i5-14401TE versus Arc Graphics 140T on the Ultra 7 255H.

Release timing differs by roughly six months. The i5-14401TE released on 2024-06-30, and the Ultra 7 255H released on 2025-01-12. Both are currently listed as Active production status. Neither part has a launch MSRP in the database, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors. However, the Ultra 7 255H has a full set of 19 recorded benchmark scores, while the i5-14401TE has none. The comparison therefore rests entirely on the Ultra 7 255H's measured results.

The largest single-score advantage appears in PassMark data compression at 298850. Floating point math follows at 98796, and integer math at 77975. Random string sorting scores 36058, extended instructions score 23755, and data encryption scores 23395. The multithread score is 30703, and the physics score is 2254.

In rendering workloads, the Ultra 7 255H scores 9240 in Cinebench R23 multi-core and 1843 in single-core. Cinebench R20 scores are 6381 multi-core and 900 single-core. Cinebench R15 scores are 1515 multi-core and 251 single-core. Geekbench results show 14024 multi-core and 2335 single-core.

The PassMark single-thread score appears twice in the data, at 4317 in both entries. The find prime numbers score is 303, which is the lowest recorded result for the Ultra 7 255H.

Relative to its nearest rivals, the Ultra 7 255H's average benchmark score of 33537 places it within 0.5% of the AMD Ryzen 5 240 (33542, 0% delta), the AMD Ryzen 7 8840HS (33667, -0.4% delta), the AMD Ryzen 5 7645HX (33668, -0.4% delta), and the Intel Core i5-12600HX (33375, +0.5% delta). The narrow deltas indicate the Ultra 7 255H sits in a competitive cluster where no single part holds a commanding lead in the database's aggregate scoring.

Since the i5-14401TE has no recorded scores, no win margin can be calculated for either direction. The data simply shows the Ultra 7 255H as the only measured part.

The Verdict

The database contains benchmark scores for only one of these two processors. The Intel Core Ultra 7 255H has 19 recorded measurements spanning Cinebench, Geekbench, and PassMark suites. The Intel Core i5-14401TE has zero recorded measurements.

For users selecting based on recorded data, the Ultra 7 255H is the only option with evidence of performance. Its 83rd percentile ranking and its position within 0.5% of four near-identical rivals (AMD Ryzen 5 240, AMD Ryzen 7 8840HS, AMD Ryzen 5 7645HX, Intel Core i5-12600HX) confirm it performs at a consistent mid-range level. The i5-14401TE's 50th percentile ranking reflects its lack of recorded benchmarks, not a measured performance level.

Architecturally, the Ultra 7 255H offers clear advantages: 16 cores versus 6, 24 MB of L3 versus 20 MB, 3 nm fabrication versus 10 nm, 5.10 GHz boost versus 4.50 GHz, and a lower 28 W TDP versus 45 W. It also supports LPDDR5X memory and provides 20 PCIe Gen 5 lanes versus 16.

The i5-14401TE retains two relevant advantages in the specification data: DDR4 memory support, which the Ultra 7 255H lacks, and a desktop socket (Intel Socket 1700) versus the mobile BGA 2049 package. Both support ECC memory, and neither has an unlocked multiplier.

For any workload where a score exists, the Ultra 7 255H delivers the measured result. The i5-14401TE cannot be positioned against it on performance grounds because the database contains no numbers for it. The selection decision, based strictly on recorded data, favors the Ultra 7 255H for every benchmark category. The i5-14401TE remains a desktop part with DDR4 compatibility, but its performance profile is unmeasured in the database.
