Intel Core i5-14401E vs Intel Core Ultra 5 235H Comparison

The Verdict

The Intel Core Ultra 5 235H is the stronger processor in every recorded benchmark comparison. Across all six head-to-head Cinebench tests, the mobile chip wins outright, with a consistent performance advantage of 29.1% in five tests and 29% in the remaining one. The Intel Core i5-14401E does not claim a single victory in the database head-to-head results.

The Core i5-14401E is a desktop part aimed at fixed systems. It uses the Intel Socket 1700 platform and carries a 65 TDP, which reflects its position as a mainstream desktop processor. Its benchmark percentile of 60 places it slightly above the median of all CPUs in the database. Its average benchmark score of 5253 sits within a tight cluster of comparable processors, including the Intel Xeon E5-2699A v4 at 5259, the Intel Core i7-11700B at 5241, and the Intel Core i9-10850K at 5240. The performance deltas against these rivals are negligible, ranging from 0.1% to 0.8%, which puts the i5-14401E in a well-populated performance tier.

The Core Ultra 5 235H is a mobile processor with a 28 TDP, designed for laptops and compact systems. It achieves an 85th percentile ranking across all CPUs, and its average benchmark score of 37522 places it in a much higher performance class. Its nearest rivals in the database are all substantially faster than the i5-14401E's peers: the Intel Core i9-13900HK scores 37425, the Intel Core i5-13600K scores 37685, the Intel Core Ultra 5 225F scores 37313, and the AMD Ryzen AI 5 PRO 435 scores 37762. The deltas among these rivals are small, between 0.3% and 0.6%, indicating that the 235H is competitive with a generation of high-end desktop and mobile parts.

The clear recommendation from the data: the Core Ultra 5 235H is the choice for anyone who wants maximum compute performance in a mobile package. The Core i5-14401E is the option for desktop builders who need a capable 6-core processor on the LGA 1700 platform, but it does not compete with the 235H on raw speed. The benchmark data shows no scenario where the i5-14401E outperforms the 235H.

Architecture Differences

The two processors come from different architectural generations and target different physical environments. The Core i5-14401E uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process node. It is a desktop chip with 6 cores and 12 threads, meaning it uses Hyper-Threading to double its thread count. Its die size is recorded at 215 mm².

The Core Ultra 5 235H uses the Arrow Lake architecture, specifically Arrow Lake-H, built on TSMC's 3 nm process node. It is a mobile chip with 14 cores and 14 threads, which indicates a hybrid arrangement where not all cores contribute additional threads. The 235H has no recorded die size in the database.

The process node difference is significant: 10 nm for the desktop part versus 3 nm for the mobile part. The smaller node allows the 235H to fit more cores into a mobile power envelope, as reflected by its 28 TDP versus the i5-14401E's 65 TDP.

Cache configurations differ substantially. The i5-14401E has 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The 235H has 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3. Per-core cache is larger on the 235H, while total L3 is slightly larger on the i5-14401E.

Memory support also separates the two. The i5-14401E supports DDR4 and DDR5 in a dual-channel configuration and includes ECC memory support. The 235H supports DDR5 and LPDDR5X in dual-channel, has a recorded memory bandwidth of 102.4 GB/s, and does not support ECC.

PCIe connectivity differs: the i5-14401E provides 16 CPU lanes of Gen 5, while the 235H provides 8 CPU lanes of Gen 5. The integrated graphics are different as well, with the i5-14401E using UHD Graphics 730 and the 235H using Arc Graphics 140T.

Where Each One Wins

The Core Ultra 5 235H wins every benchmark in the database. There are no recorded wins for the Core i5-14401E. The head-to-head results show a sweep of six Cinebench tests, covering both multicore and single-core workloads across three Cinebench versions.

The 235H demonstrates its strength in both threaded and single-threaded work. Its single-core scores are consistently 29.1% higher than the i5-14401E across Cinebench R15, R20, and R23. Its multicore scores are also 29.1% higher in R15, R20, and R23, with the R23 multicore test showing a 29% difference. This consistency indicates that the 235H's advantage comes from both higher clock speeds and better per-core efficiency.

The i5-14401E still serves a purpose as a desktop processor. Its 65 TDP and Socket 1700 compatibility make it a drop-in option for existing desktop boards. Its 16 PCIe Gen 5 lanes provide more direct CPU connectivity for expansion cards. Its ECC memory support is a feature not present on the 235H. For users who need a locked, non-unlocked desktop chip with ECC and broad PCIe connectivity, the i5-14401E remains viable.

However, the data does not support any performance use case where the i5-14401E beats the 235H. The mobile part is faster in every measured category, including single-threaded responsiveness and heavily threaded rendering workloads.

Head-to-Head Benchmarks

The head-to-head data shows a uniform 29.1% advantage for the Core Ultra 5 235H across five of the six recorded Cinebench tests, with the sixth test showing a 29% advantage.

In Cinebench R15 multicore, the i5-14401E scores 1830 and the 235H scores 2580. That is a 750-point gap, or 29.1%. In single-core R15, the i5-14401E scores 258 and the 235H scores 364, a 106-point gap at the same 29.1% delta.

Cinebench R20 shows a similar pattern. The multicore test has the i5-14401E at 7627 and the 235H at 10751, a difference of 3124 points. The single-core test has the i5-14401E at 1076 and the 235H at 1517, a difference of 441 points. Both gaps represent a 29.1% advantage for the 235H.

Cinebench R23 confirms the trend. In multicore, the i5-14401E scores 18161 and the 235H scores 25598, a gap of 7437 points. The single-core test shows the i5-14401E at 2564 and the 235H at 3613, a gap of 1049 points. The multicore delta is 29%, while the single-core delta is 29.1%.

The consistency of these deltas is notable. A 29.1% advantage in both single-core and multicore workloads suggests that the 235H benefits from a combination of higher boost clock (5.00 GHz versus 4.70 GHz), a more advanced 3 nm process node, and larger per-core caches. The i5-14401E cannot close the gap in any test, regardless of whether the workload scales across cores or relies on a single thread.

The percentile data reinforces the head-to-head results. The 235H sits at the 85th percentile of all CPUs, while the i5-14401E sits at the 60th. The average benchmark score difference is even more pronounced: 37522 for the 235H versus 5253 for the i5-14401E. The 235H's nearest rivals include desktop parts like the Core i5-13600K and mobile parts like the Core i9-13900HK, both of which score close to the 235H. The i5-14401E's nearest rivals are older or lower-tier parts like the Xeon E5-2699A v4 and the Core i9-10850K.
