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

Where Each One Wins

The Intel Core i7-14701E and the Intel Core Ultra 7 155HL occupy different performance tiers, and the recorded data shows a clear split. The Core i7-14701E, with its 8 cores and 16 threads, delivers substantial multi-threaded and single-threaded performance, placing it at the 83rd percentile among all CPUs in the database. The Core Ultra 7 155HL, despite having 16 cores and 22 threads, sits at the 50th percentile, indicating a lower overall performance profile relative to the broader CPU landscape.

Benchmark results for the Core i7-14701E show strong across-the-board scores. In Cinebench R23, it records 22,195 points in multi-core and 3,133 points in single-core. The Core Ultra 7 155HL has no recorded benchmark scores in the database, meaning all direct performance comparisons must rely on the Core i7-14701E's absolute numbers and its position relative to its nearest rivals. The Core i7-14701E's average benchmark score is 33,206, while the Core Ultra 7 155HL has an average score of zero, reflecting the absence of test data.

The Core i7-14701E wins in every measurable category by default, since the Core Ultra 7 155HL lacks recorded results. This includes Cinebench R15, R20, and R23 multi-core and single-core tests, as well as PassMark workloads such as integer math, floating-point math, data compression, data encryption, extended instructions, prime number finding, multithread, physics, random string sorting, and single-thread tests. For users seeking a processor with verified performance data, the Core i7-14701E is the only option between these two with concrete numbers to analyze.

Architecture Differences

The two processors come from different Intel architectures and generations. The Core i7-14701E is built on Raptor Lake, specifically the Raptor Lake-R refresh, part of the Core 14th Gen series. The Core Ultra 7 155HL uses Meteor Lake, specifically the Meteor Lake-PS variant, part of the Core Ultra Series 1. The process nodes differ: the Core i7-14701E uses a 10 nm node, while the Core Ultra 7 155HL uses a 7 nm node, both fabricated by Intel.

Core and thread counts differ substantially. The Core i7-14701E has 8 cores and 16 threads, while the Core Ultra 7 155HL has 16 cores and 22 threads. This means the Core Ultra 7 155HL has twice as many cores and 6 additional threads. Cache layouts also differ. The Core i7-14701E has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 33 MB of shared L3 cache. The Core Ultra 7 155HL has 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Core Ultra 7 155HL thus has more L1 cache per core but less total L3 cache.

Memory support shows a key divergence. The Core i7-14701E supports both DDR4 and DDR5 memory, while the Core Ultra 7 155HL supports DDR5 only, with the specific type depending on the motherboard. Both use dual-channel memory buses. The Core Ultra 7 155HL has a recorded memory bandwidth of 89.6 GB/s, while the Core i7-14701E has no memory bandwidth figure listed. ECC memory support also differs: the Core i7-14701E supports ECC memory, while the Core Ultra 7 155HL does not.

PCIe capabilities differ as well. The Core i7-14701E provides Gen 5 with 16 lanes (CPU only), while the Core Ultra 7 155HL provides Gen 4 with 8 lanes (CPU only). Integrated graphics differ: the Core i7-14701E uses UHD Graphics 770, while the Core Ultra 7 155HL uses Arc Xe-LPG 128EU. Sockets are incompatible: the Core i7-14701E uses Intel Socket 1700, and the Core Ultra 7 155HL uses Intel Socket 1851. The die size for the Core i7-14701E is 257 mm², while the Core Ultra 7 155HL has no die size recorded.

Head-to-Head Benchmarks

Direct head-to-head benchmark data is absent from the database, as the Core Ultra 7 155HL has no recorded scores. The Core i7-14701E, however, provides a full suite of results that define its performance envelope. In Cinebench R23, the multi-core score of 22,195 and single-core score of 3,133 indicate strong capabilities for both heavily threaded and lightly threaded workloads. The Cinebench R20 results show 9,321 in multi-core and 1,315 in single-core, while Cinebench R15 shows 2,237 in multi-core and 315 in single-core.

PassMark results for the Core i7-14701E cover a range of computational tasks. Integer math scores 81,325, floating-point math scores 61,873, and data compression scores 282,939. Data encryption records 14,862, extended instructions score 18,528, and finding prime numbers scores 176. Multithread performance scores 26,112, physics scores 2,399, and random string sorting scores 29,158. Single-thread performance scores 4,305, as recorded in both the passmark_single_thread and passmark_singlethread tests.

Relative to its nearest rivals, the Core i7-14701E shows competitive positioning. The AMD Ryzen 9 PRO 6950H has an average score of 33,201, a delta of 0 percent versus the Core i7-14701E's 33,206. The AMD Ryzen 5 8645HS scores 33,244, a delta of -0.1 percent. The AMD Ryzen 7 7745HX scores 33,091, a delta of 0.3 percent. The Intel Core i7-13650HX scores 33,089, a delta of 0.4 percent. These deltas are small, indicating the Core i7-14701E performs essentially on par with these four rivals, slightly ahead of three of them and marginally behind one.

The Core Ultra 7 155HL, with no benchmark data, cannot be compared directly. Its 50th percentile ranking among all CPUs suggests it sits near the middle of the performance distribution, whereas the Core i7-14701E at the 83rd percentile sits well above average. The absence of scores for the Core Ultra 7 155HL means the database cannot verify its performance claims, and any assessment of its capabilities relative to the Core i7-14701E must remain qualitative.

Specification Differences

The two processors differ across several specification fields. The Core i7-14701E has a base clock of 2.60 GHz and a boost clock of 5.40 GHz. The Core Ultra 7 155HL has a base clock of 1.40 GHz and a boost clock of 4.80 GHz. The Core i7-14701E therefore has both a higher base and higher boost clock. Thermal design power differs: the Core i7-14701E is rated at 65 watts, while the Core Ultra 7 155HL is rated at 45 watts.

The Verdict

The data supports a clear choice for users who need verified performance. The Intel Core i7-14701E delivers a complete benchmark profile with strong scores across Cinebench and PassMark tests, ranking at the 83rd percentile. Its Cinebench R23 multi-core score of 22,195 and single-core score of 3,133 indicate robust performance for both parallel and single-threaded applications. The Core Ultra 7 155HL has no recorded benchmark scores, an average score of zero, and a 50th percentile ranking, so the database contains no evidence of its actual performance capabilities.

For users prioritizing raw performance with measurable results, the Core i7-14701E is the better choice. It offers higher clock speeds (2.60 GHz base, 5.40 GHz boost versus 1.40 GHz base, 4.80 GHz boost), more L3 cache (33 MB versus 24 MB), ECC memory support, PCIe Gen 5 with 16 lanes, and DDR4 compatibility in addition to DDR5. The Core Ultra 7 155HL offers more cores (16 versus 8) and threads (22 versus 16), a smaller 7 nm process node, a lower 45-watt TDP, Arc Xe-LPG 128EU graphics, and a higher L1 cache per core (112 KB versus 80 KB). It also has a launch MSRP of $438.

Users who need a processor with many cores for heavily threaded workloads and prefer a lower power envelope may consider the Core Ultra 7 155HL, but they must accept the absence of any verified performance data. Users who want a processor with proven benchmark results, higher clock speeds, and stronger overall positioning in the database should select the Core i7-14701E. The recorded data shows the Core i7-14701E is the only one of the two with measurable performance, and that performance places it comfortably above the 50th percentile where the Core Ultra 7 155HL resides.
