Intel Core i5-14401E vs Intel Core Ultra 5 135UL Comparison

Head-to-Head Benchmarks

The Core i5-14401E holds a decisive performance advantage across every measured benchmark, while the Core Ultra 5 135UL has no recorded benchmark scores in the database. The six Cinebench tests available for the i5-14401E show a consistently strong profile, with multi-core scores far exceeding single-core results. In Cinebench R23, the i5-14401E delivers a multi-core score of 18161 and a single-core score of 2564. The R20 run shows 7627 multi-core and 1076 single-core. The R15 iteration produces 1830 multi-core and 258 single-core.

Because the Core Ultra 5 135UL has no benchmark entries, direct head-to-head comparisons cannot be made from recorded data. The i5-14401E's average benchmark score of 5253 places it at the 60th percentile among all CPUs in the database. Its nearest rivals include the Intel Xeon E5-2699A v4 with an average score of 5259, a delta of -0.1%, the Intel Core i7-11700B at 5241 with a delta of +0.2%, the Intel Core i9-10850K at 5240 with a delta of +0.2%, and the Intel Core i5-13400T at 5210 with a delta of +0.8%. These margins are narrow, indicating the i5-14401E sits in a tightly contested performance band. The Core Ultra 5 135UL, by contrast, holds the 50th percentile and an average score of zero, which reflects missing data rather than actual performance parity.

The absence of benchmarks for the Ultra 5 135UL means the database cannot confirm any win for that part. The wins tally shows zero for each side, but the practical reading is that the i5-14401E is the only one of the two with measurable results. Its multi-core scores, especially the R23 figure of 18161, indicate a strong threaded workload capability. Single-core scores are proportionally solid as well, with the R23 single-core result of 2564 representing roughly 14% of the multi-core figure, a typical ratio for a processor with six cores and twelve threads.

Architecture Differences

The two processors come from different architectural generations and use different process nodes. The Core i5-14401E is based on Raptor Lake, specifically the Raptor Lake-R codename, and belongs to the Core 14th Gen series. Its process node is 10 nm, and it is built by Intel. The die size is 215 mm². The Core Ultra 5 135UL is based on Meteor Lake, specifically the Meteor Lake-PS codename, and belongs to the Core Ultra Series 1. Its process node is 7 nm, also built by Intel, and no die size is recorded.

Cache layouts differ notably. The i5-14401E provides 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 135UL provides 112 KB of L1 per core, 2 MB of L2 per core, and 12 MB of shared L3 cache. The i5-14401E has a larger L3 pool, while the Ultra 5 135UL has larger per-core L1 and L2 allocations. Neither processor includes 3D V-Cache.

Memory support splits them further. The i5-14401E supports both DDR4 and DDR5 memory with a dual-channel bus. The Ultra 5 135UL supports DDR5 only, with the specific support depending on the motherboard, and also uses a dual-channel bus. The Ultra 5 135UL lists a memory bandwidth of 89.6 GB/s, while the i5-14401E has no recorded memory bandwidth figure. ECC memory is supported on the i5-14401E but not on the Ultra 5 135UL.

PCIe capabilities differ by generation and lane count. The i5-14401E uses PCIe Gen 5 with 16 lanes available from the CPU. The Ultra 5 135UL uses PCIe Gen 4 with 8 lanes from the CPU. Integrated graphics also differ: the i5-14401E includes UHD Graphics 730, while the Ultra 5 135UL includes Arc Xe-LPG 64EU. Both processors have locked multipliers, meaning neither supports unlocked overclocking.

Sockets are incompatible. The i5-14401E uses Intel Socket 1700, while the Ultra 5 135UL uses Intel Socket 1851. The release dates are close, with the i5-14401E released on 2024-06-30 and the Ultra 5 135UL released on 2024-04-07. Both are listed as Active in production status and target the Desktop market segment. The Ultra 5 135UL has a launch MSRP of $331.

The Verdict

The data clearly favors the Core i5-14401E for any workload where measured performance matters. It holds a 60th percentile ranking with an average score of 5253, and its Cinebench results show a capable multi-core part. The Core Ultra 5 135UL has no recorded benchmark data, so no performance claim can be made for it from the database. Its 50th percentile ranking is based on no average score, which means the position is unverified.

For users who prioritize raw compute results, the i5-14401E is the only one of the two with evidence of performance. Its six cores and twelve threads, combined with a 4.70 GHz boost clock, deliver strong scores in threaded and single-threaded tests. The Ultra 5 135UL offers more cores and threads, 12 and 14 respectively, but without benchmark scores, that specification cannot be translated into measured advantage.

The Ultra 5 135UL does have distinguishing attributes in the database: a lower TDP of 15 watts compared to 65 watts, a smaller 7 nm process node, larger per-core L1 and L2 caches, a recorded memory bandwidth of 89.6 GB/s, and newer PCIe Gen 4 with 8 lanes. These are architectural facts, but they do not substitute for performance data. The verdict from the recorded information is that the i5-14401E is the proven performer, while the Ultra 5 135UL remains unmeasured.

Where Each One Wins

The Core i5-14401E wins on every measurable performance metric. Its Cinebench scores establish a clear multi-core and single-core presence. The R23 multi-core score of 18161 and single-core score of 2564 are the strongest recorded results between the two. The R20 and R15 runs follow the same pattern. Its average benchmark score of 5253 and 60th percentile rank provide context against the broader CPU field. Its nearest rival comparisons show it within 0.8% of four other processors, meaning it holds its own in a competitive band. The i5-14401E also wins on boost clock, L3 cache size, PCIe Gen 5 support with 16 lanes, and ECC memory support.

The Core Ultra 5 135UL wins on specifications that favor efficiency and platform modernity. Its TDP of 15 watts is a fraction of the i5-14401E's 65 watts, indicating a much lower power envelope. Its 7 nm process node is smaller than the 10 nm node of the i5-14401E. It has more cores and threads, 12 and 14 versus 6 and 12, which suggests potential for parallel workloads, although no benchmark confirms this. Its per-core L1 and L2 caches are larger, at 112 KB and 2 MB respectively. It has a recorded memory bandwidth of 89.6 GB/s, a figure absent for the i5-14401E. Its integrated graphics, Arc Xe-LPG 64EU, is a different class of GPU than UHD Graphics 730, potentially offering stronger visual output, though no graphics benchmarks are recorded. The Ultra 5 135UL also uses the newer Intel Socket 1851 and has a launch MSRP of $331.

In practical terms, the i5-14401E is the choice for applications where benchmark scores matter, such as rendering, compilation, or other threaded workloads that respond to high clock speeds and substantial L3 cache. The Ultra 5 135UL is the choice for low-power or compact builds where the 15 watt TDP and smaller process node are priorities, and where the additional cores could be leveraged, provided software scales beyond the i5-14401E's six cores. The database does not contain evidence that the Ultra 5 135UL outperforms the i5-14401E in any recorded test, so any advantage for that part rests entirely on its specification sheet.
