Intel Core i7-14701E vs Intel Core Ultra 5 238V Comparison

Head-to-Head Benchmarks

The benchmark data shows a complete sweep in favor of the Intel Core i7-14701E. Across all 17 recorded head-to-head tests, the desktop part wins every single one, with the Core Ultra 5 238V failing to claim a single victory. The margin is not uniform, however, and the distribution of deltas tells a clear story about where each architecture excels.

The most decisive win comes in PassMark integer math, where the i7-14701E scores 81325 against 38889 for the Ultra 5 238V, a 109.1% advantage. This is more than double the throughput, and it reflects the fundamental difference in thread count and clock speed between the two. The i7-14701E also shows a 60.3% lead in data compression (282939 vs 176532) and a 55.2% lead in physics (2399 vs 1546). These are workloads that scale with both core count and raw frequency, and the desktop part has both in its favor.

The Cinebench results are uniformly 41.9% higher for the i7-14701E across all six tests, from R15 multicore (2237 vs 1576) through R23 singlecore (3133 vs 2208). The consistency of that 41.9% delta across both single and multicore tests indicates a clock-speed and IPC advantage that applies broadly, not just in heavily threaded scenarios. The single-thread PassMark result is closer, at 10.7% (4305 vs 3890), which suggests the Lunar Lake architecture is competitive on a per-core basis, but the gap still favors the older part.

Smaller margins appear in less demanding tasks. The find prime numbers test shows only a 1.1% difference (176 vs 174), nearly a tie. Data encryption shows a 13.7% lead for the i7-14701E (14862 vs 13072), and floating point math shows 16.4% (61873 vs 53160). The random string sorting test gives the i7-14701E a 35.1% edge (29158 vs 21585), and extended instructions land at 20.5% (18528 vs 15377). The multithread PassMark score is 41.9% higher for the i7-14701E (26112 vs 18407), matching the Cinebench delta exactly.

The average benchmark score reinforces the gap. The i7-14701E sits at 33206, placing it in the 83rd percentile of all CPUs in the database. The Ultra 5 238V averages 21981, which ranks in the 75th percentile. The nearest rivals for the i7-14701E include the AMD Ryzen 9 PRO 6950H at 33201 (0% delta) and the AMD Ryzen 7 7745HX at 33091 (0.3% delta). The Ultra 5 238V's nearest rivals include the Intel Core i7-11700F at 21988 (0% delta) and the AMD Ryzen 5 3600X at 21992 (0% delta). These comparison points show that the i7-14701E competes with high-end mobile and desktop chips, while the Ultra 5 238V sits in the performance range of older mid-range desktop parts.

Architecture Differences

The two processors come from different Intel generations with fundamentally different designs. The i7-14701E uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process. It is a desktop part on the Intel Socket 1700 platform. The Ultra 5 238V uses the Lunar Lake architecture, built on TSMC's 3 nm process, and is a mobile part on the Intel BGA 2833 socket. The difference in process node is significant: 10 nm versus 3 nm, which explains the power envelope gap between the two.

Both have 8 cores, but the threading differs. The i7-14701E supports 16 threads, while the Ultra 5 238V supports only 8. This is a key architectural distinction. The desktop part uses hyperthreading to double its thread count, while the mobile part does not. The cache hierarchy also differs. The i7-14701E has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 5 238V has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 8 MB of shared L3. The larger L3 on the desktop part is a major advantage for workloads that repeatedly access a large working set.

Clock speeds tell a similar story. The i7-14701E has a base clock of 2.60 GHz and a boost clock of 5.40 GHz. The Ultra 5 238V has a base clock of 2.10 GHz and a boost clock of 4.70 GHz. The desktop part is 0.5 GHz higher at base and 0.7 GHz higher at boost. The TDP difference is dramatic: 65 watts for the i7-14701E versus 17 watts for the Ultra 5 238V. This is the defining trade-off of the comparison. The desktop part consumes nearly four times the power to deliver its performance advantage.

Memory support also diverges. The i7-14701E supports both DDR4 and DDR5, while the Ultra 5 238V's memory support is listed as dependent on the motherboard. Both use dual-channel memory buses. ECC memory is supported on the i7-14701E but not on the Ultra 5 238V. PCIe lanes differ as well: the i7-14701E provides 16 Gen 5 lanes from the CPU, while the Ultra 5 238V provides only 4 Gen 5 lanes. Integrated graphics are present on both, with the UHD Graphics 770 on the desktop part and the Arc 130V on the mobile part.

The release dates place the i7-14701E in June 2024 and the Ultra 5 238V in September 2024, three months apart. Both remain in active production. Neither has a multiplier unlocked, so overclocking is restricted on both.

The Verdict

The data is unambiguous. The i7-14701E outperforms the Ultra 5 238V in every recorded benchmark, with an average score of 33206 versus 21981, a 51.2% difference. The 83rd percentile ranking for the i7-14701E versus the 75th percentile for the Ultra 5 238V places them in different performance tiers entirely.

The deciding factor is the intended use case. The i7-14701E is a desktop processor with a 65 W TDP, a 5.40 GHz boost clock, 16 threads, and 33 MB of L3 cache. It delivers 41.9% higher Cinebench scores across the board and more than double the integer math throughput. This is a part designed for sustained heavy workloads where power consumption is not the primary constraint.

The Ultra 5 238V is a mobile processor with a 17 W TDP, a 4.70 GHz boost clock, 8 threads, and 8 MB of L3 cache. It cannot match the desktop part in any measured metric, but its entire design goal is efficiency. The 3 nm process node from TSMC and the low TDP make it suitable for thin-and-light laptops where battery life and thermal limits dominate.

For a desktop system where performance is the priority, the i7-14701E is the obvious choice from this data. For a mobile system where the 17 W TDP is a requirement, the Ultra 5 238V is the only option that fits. The benchmarks do not show any scenario where the Ultra 5 238V offers a performance advantage, so the selection comes down to platform and power constraints, not raw capability.

Where Each One Wins

The i7-14701E wins all 17 head-to-head tests, so the practical question is not which workloads favor it, but by how much. The largest margins appear in integer math (109.1%), data compression (60.3%), and physics (55.2%). These are heavily threaded workloads that exploit the 16 threads and the 33 MB L3 cache. The smallest margin is in find prime numbers (1.1%), which is a nearly even contest. This suggests that the Ultra 5 238V's per-core efficiency on the 3 nm process closes the gap in simple integer loops, but it cannot overcome the desktop part's clock and thread advantages elsewhere.

Single-thread performance favors the i7-14701E by 10.7% in PassMark and 41.9% in Cinebench R23 singlecore. The Cinebench singlecore gap is much larger than the PassMark gap, which indicates the i7-14701E scales better under the specific instruction mix in Cinebench. The Ultra 5 238V's closest results are in encryption (13.7% behind) and floating point math (16.4% behind), where its higher L1 cache per core (192 KB vs 80 KB) partially compensates for its lower clocks.

The Ultra 5 238V does not win any recorded test, but its 17 W TDP makes it the only viable choice for platforms that require that power envelope. The i7-14701E, with its 65 W TDP and desktop socket, is not an alternative in such systems. The data shows a pure performance hierarchy, but the platform constraint is the real separator. For anyone building a desktop system with access to standard ATX power delivery, the i7-14701E is faster in every measured category. For anyone constrained to a 17 W mobile platform, the Ultra 5 238V is the part that fits, and its efficiency is the trade-off that makes it usable in devices where the i7-14701E cannot physically be installed.
