The Verdict

The data clearly splits these two processors into distinct usage categories. The Intel Core i5-14501E is a desktop part using the LGA 1700 socket, Raptor Lake architecture, and a 65-watt TDP. It is built for systems where a fixed installation, higher power budget, and desktop memory options like DDR4 and DDR5 are the norm. Its 6 cores with 12 threads and a 5.20 GHz boost clock make it a strong candidate for a traditional desktop workstation.

The Intel Core Ultra 7 258V is a mobile processor on the BGA 2833 socket, using Lunar Lake architecture and a 17-watt TDP. It uses LPDDR5X memory, which is typical for thin and light laptops. Its integrated graphics are the Arc 140V, a more substantial iGPU than the UHD Graphics 770 found on the i5-14501E.

If the primary goal is maximum multi-threaded compute in a desktop chassis with room for a dedicated GPU and higher power delivery, the i5-14501E is the logical choice. Its 12 threads and higher boost clock give it an advantage in heavily threaded workloads. However, the recorded benchmark data shows the Ultra 7 258V scoring higher in the majority of tests, including a 74th percentile ranking versus the i5-14501E's 50th percentile. For mobile users who need strong single-core performance, a powerful integrated GPU, and low power consumption, the Core Ultra 7 258V is the superior option. The data does not support a single "best" chip; it supports a choice based on platform and workload.

Head-to-Head Benchmarks

The benchmark results show a decisive overall win for the Intel Core Ultra 7 258V, which holds an average benchmark score of 20454. The i5-14501E has no recorded benchmark scores in the database, so the head-to-head comparison relies entirely on the Ultra 7's performance metrics.

Cinebench R23 results provide a clear picture. The Ultra 7 258V scores 10301 in multi-core and 1872 in single-core. Cinebench R20 scores are 6739 multi-core and 951 single-core. Cinebench R15 scores are 1596.5 multi-core and 285 single-core. These scores are all the more impressive given the 17-watt TDP of the chip.

Geekbench results show a score of 9325 for multi-core and 2100 for single-core. PassMark results show a multithread score of 18887 and a single-thread score of 4018. The PassMark suite also includes specialized tests: data compression scores 176686, data encryption scores 13534, extended instructions score 14717, find prime numbers scores 185, floating point math scores 57372, integer math scores 42889, physics scores 1565, and random string sorting scores 21580.

The nearest rivals for the Ultra 7 258V in the database are all AMD parts. The AMD Ryzen 5 5600 has an average score of 20468, which is only 0.1% higher than the Ultra 7 258V. The AMD Ryzen 5 8500G scores 20425, 0.1% lower. The AMD EPYC 9454P scores 20422, 0.2% lower. The AMD EPYC 7713 scores 20363, 0.4% lower. This places the Ultra 7 258V in close competition with the Ryzen 5 5600, a very capable desktop processor, while doing so at a fraction of the power draw.

Specification Differences

The two processors differ in nearly every fundamental specification. The i5-14501E has 6 cores and 12 threads, while the Ultra 7 258V has 8 cores but only 8 threads. The i5-14501E has a base clock of 3.30 GHz and a boost clock of 5.20 GHz. The Ultra 7 258V has a base clock of 2.20 GHz and a boost clock of 4.80 GHz.

The power envelope is a major differentiator. The i5-14501E is rated at 65 watts TDP, while the Ultra 7 258V is rated at 17 watts TDP. The i5-14501E uses the Intel Socket 1700, a desktop platform. The Ultra 7 258V uses Intel BGA 2833, a mobile platform.

Memory support also differs. The i5-14501E supports DDR4 and DDR5 memory. The Ultra 7 258V supports LPDDR5X. The Ultra 7 258V has a recorded memory bandwidth of 136.5 GB/s; no such figure is recorded for the i5-14501E. The i5-14501E supports ECC memory, while the Ultra 7 258V does not.

PCIe lanes differ: the i5-14501E provides Gen 5 with 16 lanes (CPU only), while the Ultra 7 258V provides Gen 5 with 4 lanes (CPU only). The integrated graphics are also different: the i5-14501E uses UHD Graphics 770, while the Ultra 7 258V uses Arc 140V.

The market segments are explicitly different: the i5-14501E is a Desktop part, and the Ultra 7 258V is a Mobile part. The i5-14501E was released on 2024-06-30, while the Ultra 7 258V was released on 2024-09-23.

Architecture Differences

The architectural split is significant. The Intel Core i5-14501E is built on Raptor Lake architecture, specifically the Raptor Lake-R refresh. It uses a 10 nm process node fabricated by Intel. The die size is 215 mm². Cache is organized as 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache.

The Intel Core Ultra 7 258V uses Lunar Lake architecture. It is fabricated by TSMC on a 3 nm process node. No die size is recorded for this part. Cache is organized as 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3 cache.

The cache hierarchy differences are substantial. The Ultra 7 258V has more than double the L1 cache per core (192 KB vs 80 KB) and double the L2 cache per core (2.5 MB vs 1.25 MB). The i5-14501E, however, has double the shared L3 cache (24 MB vs 12 MB). This suggests the i5-14501E relies on a larger pool of shared cache for its 12 threads, while the Ultra 7 258V provides more private cache per core.

The process node difference is a major factor. The 3 nm TSMC node on the Ultra 7 258V is a more advanced manufacturing process than the 10 nm Intel node on the i5-14501E. This is consistent with the massive TDP difference: 17 watts versus 65 watts. The Ultra 7 258V achieves higher benchmark scores while drawing far less power, which is a direct result of the newer process node and mobile-oriented design.

Where Each One Wins

The Intel Core i5-14501E wins in scenarios defined by its desktop platform attributes. It offers 12 threads versus 8, which is an advantage for heavily parallel desktop workloads that scale with thread count. Its 5.20 GHz boost clock is the highest of the two, which supports high-frequency single-thread performance in brief bursts. It supports ECC memory, making it viable for error-sensitive compute tasks. It supports both DDR4 and DDR5, allowing builders to choose cheaper or faster memory depending on the motherboard. Its 16 PCIe Gen 5 lanes provide more bandwidth for a dedicated GPU and expansion cards. The 24 MB of shared L3 cache is a benefit for workloads that share data across many threads.

The Intel Core Ultra 7 258V wins in mobile and efficiency-focused scenarios. The recorded benchmark scores show it dominating the performance charts despite its 17-watt TDP. It holds a 74th percentile ranking versus the i5-14501E's 50th. Its 8 cores and 8 threads, combined with 192 KB of L1 and 2.5 MB of L2 per core, deliver strong per-core performance. The integrated Arc 140V graphics are a far more capable iGPU than the UHD Graphics 770, making it suitable for light gaming and GPU-accelerated tasks without a discrete card. The 136.5 GB/s memory bandwidth on LPDDR5X is a high figure for a mobile chip.

The PassMark data confirms the Ultra 7 258V's strengths across a range of workloads. Data compression, encryption, integer math, floating point math, and physics tests all show strong results. Its closest rival, the AMD Ryzen 5 5600, is a desktop processor with a much higher power envelope, yet the Ultra 7 258V nearly matches it in average score (20454 vs 20468). This indicates that the Ultra 7 258V delivers desktop-class compute in a mobile form factor. The i5-14501E, with no recorded benchmark scores, cannot be positioned on the same performance scale. The clear win for the Ultra 7 258V is in overall performance per watt and in the mobile segment.
