Intel Core i5-14501E vs Intel Core Ultra 7 155UL Comparison

Head-to-Head Benchmarks

The recorded data for this comparison contains no head-to-head benchmark results. Neither the Intel Core i5-14501E nor the Intel Core Ultra 7 155UL has any benchmark entries in the database, and both processors hold an identical percentile ranking of 50 against all CPUs. The average benchmark score for each is zero, which means no measured performance data exists to separate these two parts empirically.

Without direct measurements, the specification sheet becomes the only available evidence. The Core i5-14501E operates with a base clock of 3.30 GHz and a boost clock of 5.20 GHz, while the Core Ultra 7 155UL operates at 1.70 GHz base and 4.80 GHz boost. The Core i5-14501E leads the Core Ultra 7 155UL by 1.60 GHz at base frequency and 0.40 GHz at boost frequency. Clock advantage of this magnitude typically favors the Core i5-14501E in lightly threaded workloads where frequency scaling dominates.

The Core Ultra 7 155UL counters with 12 cores and 14 threads, while the Core i5-14501E provides 6 cores and 12 threads. The Core Ultra 7 155UL offers double the physical core count and two additional threads. Multi-threaded workloads that scale across many cores would likely favor the Core Ultra 7 155UL, assuming the software can utilize all available execution resources.

Power envelopes diverge sharply. The Core i5-14501E carries a 65 TDP rating, while the Core Ultra 7 155UL carries a 15 TDP rating. The Core i5-14501E is allowed over four times the thermal budget. Sustained all-core operation on the Core Ultra 7 155UL may be constrained by its modest power allocation, potentially limiting its multi-threaded advantage in extended workloads.

Memory bandwidth figures appear in the database for the Core Ultra 7 155UL at 89.6 GB/s, while the Core i5-14501E has no recorded memory bandwidth value. The Core Ultra 7 155UL also supports only DDR5 memory with capacity dependent on the motherboard, whereas the Core i5-14501E supports both DDR4 and DDR5. The Core i5-14501E enables ECC memory, and the Core Ultra 7 155UL does not.

The integrated graphics present a notable split. The Core i5-14501E uses UHD Graphics 770, and the Core Ultra 7 155UL uses Arc Xe-LPG 64EU. The Arc Xe-LPG 64EU in the Core Ultra 7 155UL represents a newer graphics architecture from the Meteor Lake generation, which may deliver stronger GPU compute performance. No graphics benchmark data exists in the pack, so any conclusion remains provisional.

PCIe connectivity differs as well. The Core i5-14501E provides Gen 5 with 16 lanes from the CPU, and the Core Ultra 7 155UL provides Gen 4 with 8 lanes from the CPU. The Core i5-14501E supports faster and more numerous PCIe lanes for expansion devices such as discrete GPUs and NVMe storage.

The Verdict

The database shows two processors with no measured benchmark results, so the verdict must rest on the specification record. The Intel Core i5-14501E pairs a 5.20 GHz boost clock with 6 cores, 12 threads, and 24 MB of L3 cache. The Intel Core Ultra 7 155UL pairs a 4.80 GHz boost clock with 12 cores, 14 threads, and 12 MB of L3 cache.

The Core i5-14501E appears optimized for frequency-sensitive workloads. Its higher base and boost clocks, larger L3 cache, PCIe Gen 5 support with 16 lanes, ECC memory capability, and dual DDR4/DDR5 support position it as a conventional desktop part with broad platform compatibility. The 65 TDP suggests it can sustain higher clocks under load.

The Core Ultra 7 155UL appears optimized for efficiency and parallelism. Its 7 nm process, 15 TDP, 12 cores, and 14 threads indicate a design focused on power efficiency and multi-threaded throughput per watt. The Arc Xe-LPG 64EU integrated graphics and 89.6 GB/s memory bandwidth point toward integrated system use cases.

The data indicates a trade-off between frequency and core count. The Core i5-14501E should excel where single-thread performance matters most, given its 5.20 GHz boost clock and smaller core count. The Core Ultra 7 155UL should excel where many threads are active, given its 12 physical cores, provided the 15 TDP does not throttle sustained operation.

The release dates place the Core Ultra 7 155UL earlier at 2024-04-07, with the Core i5-14501E following at 2024-06-30. Both are Active production parts. The Core Ultra 7 155UL carries a launch MSRP of $426, and the Core i5-14501E has no recorded launch MSRP.

Neither part has an unlocked multiplier, so overclocking is not a differentiating factor.

Where Each One Wins

The Intel Core i5-14501E wins in single-thread and lightly threaded scenarios based on clock speed. Its 5.20 GHz boost clock exceeds the Core Ultra 7 155UL's 4.80 GHz boost clock by 0.40 GHz, and its 3.30 GHz base clock exceeds the Core Ultra 7 155UL's 1.70 GHz base clock by 1.60 GHz. Applications that depend on high frequency per core, such as older game engines or latency-sensitive single-threaded tasks, align with this part.

The Core i5-14501E also wins on cache capacity. Its 24 MB of shared L3 cache doubles the Core Ultra 7 155UL's 12 MB. Larger L3 cache can reduce memory traffic in workloads with moderate working sets. The Core i5-14501E additionally supports ECC memory, a feature absent from the Core Ultra 7 155UL, which matters for data-integrity-sensitive environments.

Platform expansion favors the Core i5-14501E. PCIe Gen 5 with 16 CPU lanes versus Gen 4 with 8 CPU lanes means the Core i5-14501E supports faster and more numerous expansion devices. DDR4 support alongside DDR5 gives the Core i5-14501E flexibility across a wider range of motherboards and memory kits.

The Intel Core Ultra 7 155UL wins in multi-threaded throughput potential. Its 12 cores and 14 threads double the physical core count of the Core i5-14501E and add 2 threads beyond the Core i5-14501E's 12. Workloads that spread across many cores, such as rendering, compilation, or virtualization, align with this part, assuming the 15 TDP allows sustained operation.

The Core Ultra 7 155UL wins on power efficiency. Its 15 TDP versus 65 TDP represents a 50-watt difference in thermal design power. Systems constrained by cooling or power budgets favor the Core Ultra 7 155UL. The 7 nm process node versus 10 nm also supports this efficiency advantage.

Integrated graphics favor the Core Ultra 7 155UL on architecture generation. Arc Xe-LPG 64EU represents a newer GPU design than UHD Graphics 770. The 89.6 GB/s memory bandwidth figure for the Core Ultra 7 155UL also supports graphics and memory-intensive integrated workloads, though no graphics benchmarks confirm this.

The Core Ultra 7 155UL wins on per-core cache size. Its 112 KB L1 per core and 2 MB L2 per core exceed the Core i5-14501E's 80 KB and 1.25 MB per-core values. Larger per-core caches can improve performance in workloads with high per-thread locality.

The release timing puts the Core Ultra 7 155UL earlier in 2024-04-07, while the Core i5-14501E arrived later on 2024-06-30. Both remain active production parts. The absence of benchmark data leaves these as directional conclusions from the specification record, not measured outcomes.
