Architecture Differences

The two processors come from different architectural families. The i5-14401E uses the Raptor Lake architecture, specifically Raptor Lake-R, and is part of the Core i5 generation labeled Raptor Lake Refresh. The Ultra 7 165UL uses the Meteor Lake architecture, specifically Meteor Lake-PS, and belongs to the Ultra 7 generation. This architectural split explains many of the differences in their specifications and performance characteristics.

The manufacturing process differs as well. The i5-14401E is fabricated on a 10 nm process node, while the Ultra 7 165UL is fabricated on a 7 nm process node. Both are manufactured by Intel, but the newer node for the Ultra 7 part allows for a different transistor density and power profile.

Cache layouts are distinct between the two. The i5-14401E has an L1 cache of 80 KB per core, an L2 cache of 1.25 MB per core, and a shared L3 cache of 20 MB. The Ultra 7 165UL has a larger per-core L1 cache at 112 KB per core, a larger L2 cache at 2 MB per core, but a smaller shared L3 cache at 12 MB. The die size for the i5-14401E is listed as 215 mm², while the die size for the Ultra 7 165UL is not recorded in the database.

PCIe capabilities also differ. The i5-14401E provides PCIe Gen 5 with 16 lanes from the CPU. The Ultra 7 165UL provides PCIe Gen 4 with 8 lanes from the CPU. This means the i5-14401E offers a newer PCIe generation and more lanes for expansion.

Memory bandwidth is another differentiating factor. The i5-14401E does not have a recorded memory bandwidth figure in the database. The Ultra 7 165UL has a recorded memory bandwidth of 89.6 GB/s. Both use dual-channel memory buses, but the i5-14401E supports both DDR4 and DDR5, while the Ultra 7 165UL supports DDR5 only.

The release dates differ. The i5-14401E was released on 2024-06-30, while the Ultra 7 165UL was released earlier on 2024-04-07. Both processors are currently marked as active in production status, and neither has an unlocked multiplier.

Where Each One Wins

The i5-14401E shows clear strengths in single-core performance based on its benchmark results. Its Cinebench R15 single-core score is 258, its R20 single-core score is 1076, and its R23 single-core score is 2564. The higher boost clock of the Ultra 7 165UL at 4.90 GHz compared to the i5-14401E's 4.70 GHz suggests the Ultra 7 part could compete in single-threaded tasks, but without recorded benchmark scores for the Ultra 7, the i5-14401E remains the measured leader in this area.

The Ultra 7 165UL has advantages in core count and thread count. With 12 cores and 14 threads versus the i5-14401E's 6 cores and 12 threads, the Ultra 7 part is designed for workloads that scale across many threads. The larger L1 and L2 caches per core on the Ultra 7 165UL also provide more local cache resources for each core.

Power efficiency is a major differentiator. The Ultra 7 165UL has a TDP of 15 watts, which is significantly lower than the i5-14401E's 65 watts. This makes the Ultra 7 165UL suitable for systems where power consumption and thermal output are primary concerns. The i5-14401E, with its higher TDP, can sustain higher clocks for desktop workloads that demand more power.

The i5-14401E supports ECC memory, which is important for error-sensitive computing environments. The Ultra 7 165UL does not support ECC memory. The i5-14401E also supports older DDR4 memory, which can be an advantage for system builders with existing DDR4 modules, while the Ultra 7 165UL requires DDR5.

Integrated graphics favor the Ultra 7 165UL. Its Arc Xe-LPG 64EU graphics solution is a more capable GPU compared to the UHD Graphics 730 in the i5-14401E. For systems relying on integrated graphics for display output or light media tasks, the Ultra 7 165UL has the stronger offering.

The i5-14401E has a higher base clock by 0.80 GHz, but the Ultra 7 165UL has a higher boost clock by 0.20 GHz. The i5-14401E has double the L3 cache of the Ultra 7 165UL, at 20 MB versus 12 MB. The Ultra 7 165UL, in turn, has larger L1 and L2 caches per core. The i5-14401E offers more PCIe lanes and a newer PCIe generation, while the Ultra 7 165UL offers a higher memory bandwidth figure. Both parts are locked, meaning the multiplier is not unlocked for overclocking.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for these two processors. The wins counter shows 0 for both items, and the headToHeadBenchmarks array is empty. The Ultra 7 165UL has no recorded benchmark scores at all, with an average benchmark score of 0 and no nearest rivals listed.

The i5-14401E, however, has a full set of Cinebench results. Its Cinebench R15 multicore score is 1830, and its R15 single-core score is 258. In Cinebench R20, the i5-14401E scores 7627 multicore and 1076 single-core. In Cinebench R23, the multicore score is 18161 and the single-core score is 2564. These scores place the i5-14401E at the 60th percentile of all CPUs in the database.

The i5-14401E's nearest rivals in the database provide context for its performance. The Intel Xeon E5-2699A v4 has an average score of 5259, which is 0.1% higher than the i5-14401E's 5253. The Intel Core i7-11700B has an average score of 5241, which is 0.2% lower. The Intel Core i9-10850K also has an average score of 5240, 0.2% lower. The Intel Core i5-13400T has an average score of 5210, which is 0.8% lower. These deltas show the i5-14401E sits in a tightly packed performance cluster with these four processors.

Because the Ultra 7 165UL has no benchmark entries, its relative performance cannot be quantified against the i5-14401E using the database. The specification data indicates the Ultra 7 165UL has more cores, more threads, a higher boost clock, and a lower TDP, but the absence of measured scores means no direct comparison of rendering or compute performance is possible from the recorded data.

The percentile data reinforces this gap. The i5-14401E sits at the 60th percentile of all CPUs, while the Ultra 7 165UL sits at the 50th percentile. This difference suggests the i5-14401E outperforms a larger share of the CPU population in the database, although the percentile for the Ultra 7 165UL is calculated without any benchmark scores, which limits its interpretability.

The Verdict

The data shows two processors with clearly different design intents. The Intel Core i5-14401E is a desktop CPU with a 65 W TDP, 6 cores, 12 threads, and a boost clock of 4.70 GHz. It has measured Cinebench scores across R15, R20, and R23, and it ranks at the 60th percentile of all CPUs. Its nearest rivals are within 0.8% of its average benchmark score, indicating it performs in line with processors like the Intel Core i7-11700B and Intel Core i9-10850K.

The Intel Core Ultra 7 165UL is a 15 W part with 12 cores, 14 threads, and a boost clock of 4.90 GHz. It uses the Meteor Lake architecture on a 7 nm node, includes Arc Xe-LPG 64EU integrated graphics, and supports DDR5 memory with a memory bandwidth of 89.6 GB/s. Its launch MSRP is $447. The database has no benchmark scores for this processor, so its measured performance cannot be compared directly.

For workloads where measured performance matters, the i5-14401E is the only one of the two with recorded results. Its Cinebench R23 multicore score of 18161 and single-core score of 2564 represent its measured capabilities. For workloads where power efficiency is the priority, the Ultra 7 165UL offers a 15 W TDP, which is considerably lower than the i5-14401E's 65 W TDP.

The choice between these two processors depends on the requirements. Systems that need ECC memory support, DDR4 compatibility, PCIe Gen 5 with 16 lanes, and a larger 20 MB L3 cache would align with the i5-14401E. Systems that need more cores, more threads, a higher boost clock, a newer 7 nm process node, and stronger integrated graphics would align with the Ultra 7 165UL. The i5-14401E also has a higher percentile ranking and recorded benchmark scores, while the Ultra 7 165UL has a lower TDP and a larger per-core cache configuration.

Neither processor has an unlocked multiplier, so overclocking is not an option for either. Both are active in production and both are desktop market segments. The i5-14401E uses Intel Socket 1700, while the Ultra 7 165UL uses Intel Socket 1851, so motherboard compatibility is a deciding factor. The Ultra 7 165UL requires DDR5, while the i5-14401E can use either DDR4 or DDR5. The i5-14401E supports ECC memory, while the Ultra 7 165UL does not.

The lack of benchmark data for the Ultra 7 165UL means the database cannot confirm its performance level. The i5-14401E, by contrast, has a complete benchmark profile and a clear position among its nearest rivals. For users who require verified performance numbers, the i5-14401E is the part with the measurements. For users who prioritize low power draw, high core count, and integrated graphics capability, the Ultra 7 165UL has the specifications that support those goals.
