Intel Core i7-14701E vs Intel Core Ultra 7 155UL Comparison

Where Each One Wins

The Intel Core i7-14701E and the Intel Core Ultra 7 155UL occupy very different positions in the desktop processor landscape. The data shows a clear split: the i7-14701E is built for sustained, high-throughput compute, while the Ultra 7 155UL is engineered for efficiency and integrated graphics capability.

The i7-14701E holds every recorded benchmark win. It delivers 8 cores and 16 threads, a combination that drives its multicore results across all Cinebench versions. Its single-core performance also leads, with a boost clock of 5.40 GHz enabling strong results in lightly threaded workloads. The database places this chip at the 83rd percentile among all CPUs, indicating it outperforms the vast majority of processors in the measured suite.

The Ultra 7 155UL, by contrast, has no recorded benchmark scores in the database. Its percentile ranking sits at 50, and its average benchmark score is zero. This does not mean the chip is nonfunctional; rather, the database lacks measurements for it. What the specification sheet does show is a 12-core, 14-thread design with a 15 W TDP, a drastically lower power envelope than the i7-14701E's 65 W. The Ultra 7 also integrates Arc Xe-LPG 64EU graphics, a more capable iGPU than the UHD Graphics 770 found in the i7-14701E.

The implied use-case split is therefore straightforward. The i7-14701E wins on raw compute, both multicore and single-core. The Ultra 7 155UL wins on power efficiency and integrated graphics, making it suitable for compact or passively cooled systems where the i7-14701E's higher power draw would be problematic.

Architecture Differences

These two processors come from different Intel generations and use fundamentally different designs. The i7-14701E is based on Raptor Lake-R, part of the Core 14th Gen family, fabricated on Intel's 10 nm process. Its die size is 257 mm², and it uses a monolithic architecture. The Ultra 7 155UL is a Meteor Lake-PS part from the Core Ultra Series 1 family, built on a 7 nm process. Meteor Lake uses a tile-based, chiplet design, though the database does not provide die size figures for it.

Core counts differ significantly. The i7-14701E has 8 cores and 16 threads, all of which are performance cores in the Raptor Lake design. The Ultra 7 155UL has 12 cores but only 14 threads, which indicates a hybrid layout with both performance and efficiency cores, where not all cores contribute additional threads. Cache hierarchies also diverge. The i7-14701E offers 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Ultra 7 155UL has 112 KB of L1 per core, 2 MB of L2 per core, but only 12 MB of shared L3. The larger L3 on the i7-14701E is a substantial advantage for workloads that repeatedly access large datasets.

Memory support differs as well. The i7-14701E supports both DDR4 and DDR5, while the Ultra 7 155UL supports DDR5 only, with capacity depending on the motherboard. The Ultra 7 lists a memory bandwidth of 89.6 GB/s; the i7-14701E does not have a recorded bandwidth figure. ECC memory is supported on the i7-14701E but not on the Ultra 7 155UL, which matters for error-sensitive compute tasks. PCIe capabilities also differ: the i7-14701E provides Gen 5 with 16 lanes from the CPU, while the Ultra 7 155UL provides Gen 4 with 8 lanes. The i7-14701E therefore offers more headroom for high-bandwidth expansion cards and storage.

Sockets differ entirely. The i7-14701E uses Intel Socket 1700, while the Ultra 7 155UL uses Intel Socket 1851. These are not interchangeable, so platform choice is fixed once a CPU is selected. The i7-14701E launched on 2024-06-30, while the Ultra 7 155UL launched earlier on 2024-04-07. Both parts remain in active production.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty in the database. No direct comparison scores exist between the i7-14701E and the Ultra 7 155UL. However, the i7-14701E has a full set of Cinebench and PassMark results that establish its performance profile.

In Cinebench R23, the i7-14701E scores 22195 in multicore and 3133 in single-core. The multicore figure reflects its 8-core, 16-thread configuration and 33 MB of L3 cache. The single-core score benefits from the 5.40 GHz boost clock. In Cinebench R20, the scores are 9321 multicore and 1315 single-core. In Cinebench R15, the scores are 2237 multicore and 315 single-core. These results scale consistently across Cinebench versions, indicating stable performance across different rendering workloads.

PassMark results expand the picture. The i7-14701E scores 282939 in data compression, 14862 in data encryption, 18528 in extended instructions, 176 in find prime numbers, 61873 in floating point math, 81325 in integer math, 26112 in multithread, 2399 in physics, 29158 in random string sorting, and 4305 in single thread. The integer math and floating point math scores are particularly strong, suggesting good general-purpose compute capability. The data compression score is high in absolute terms, while the prime number finding score is comparatively low, which may reflect specific instruction-level behavior in that test.

The nearest rivals for the i7-14701E provide context. The AMD Ryzen 9 PRO 6950H has an average score of 33201, a 0% delta. The AMD Ryzen 5 8645HS scores 33244, a -0.1% delta. The AMD Ryzen 7 7745HX scores 33091, a 0.3% delta. The Intel Core i7-13650HX scores 33089, a 0.4% delta. These deltas are all within one percent, meaning the i7-14701E performs essentially on par with this cluster of competitors. The i7-14701E's average benchmark score is 33206, placing it right in the middle of this group.

The Ultra 7 155UL has no scores to compare. Its 50th percentile ranking, combined with zero average score, means it cannot be positioned relative to these rivals using measured data. The database simply does not have enough information to make a quantitative comparison.

The Verdict

The data supports a clear conclusion for compute-focused users. The i7-14701E is the only one of these two processors with measured performance, and those measurements are strong. Its 83rd percentile ranking, its 22195 multicore score in Cinebench R23, and its 4305 single-thread score in PassMark all indicate a capable desktop processor. Its 33 MB of L3 cache, DDR4 and DDR5 support, ECC memory capability, and PCIe Gen 5 with 16 lanes make it the more versatile choice for workloads that demand memory bandwidth, cache capacity, and expansion options.

The Ultra 7 155UL cannot be recommended on the basis of measured performance because no measurements exist. What the specification sheet shows is a 15 W TDP, 12 cores, 14 threads, and Arc Xe-LPG 64EU graphics. This combination points toward a low-power design suited for systems where heat and power draw are primary concerns. Its 7 nm process node and 89.6 GB/s memory bandwidth suggest a modern architecture, but the lack of benchmark data leaves its real-world performance unverified.

Users who need a desktop processor for rendering, compilation, or other multithreaded workloads should choose the i7-14701E. Users who prioritize low power consumption and integrated graphics capability, and who do not require the highest compute throughput, may find the Ultra 7 155UL appropriate, but they should be aware that the database provides no performance validation for it.
