Intel Core i7-1270P vs Intel Core Ultra 5 238V Comparison

The Intel Core i7-1270P and Intel Core Ultra 5 238V represent two distinct mobile design philosophies, and the benchmark data shows a clear split personality between them. The Ultra 5 238V wins 15 of 17 head-to-head tests, leveraging its newer architecture for superior efficiency and single-threaded muscle, while the i7-1270P clings to victory in only two specialized workloads—data compression and integer math—thanks to its higher core count. The data indicates the Ultra 5 238V is the better all-around performer for most users, but the i7-1270P retains niche advantages that matter for specific productivity tasks.

The Verdict

From a pure performance standpoint, the Intel Core Ultra 5 238V is the default recommendation for most mobile buyers. It posts a higher average benchmark score of 21981 against the i7-1270P’s 22502, but that aggregate figure is misleading—the Ultra 5 wins decisively in nearly every discipline that matters for modern workloads. Its Cinebench R23 multi-core score of 15645 beats the i7-1270P’s 13938 by 10.9%, and its single-core advantage is equally stark: 2208 versus 1967, again a 10.9% gap. For users running rendering, physics simulations, or encryption-heavy tasks, the Ultra 5 238V is the clear choice, delivering 13.7% better data encryption and 27.6% better physics scores.

However, the Intel Core i7-1270P is not obsolete. Its 12-core, 16-thread configuration gives it a dominant lead in integer math, scoring 63016 against the Ultra 5’s 38889—a massive 62% advantage. It also wins data compression by 4.7% (184917 versus 176532). If your workflow involves heavy spreadsheet calculations, code compilation, or file archiving, the i7-1270P’s extra cores provide tangible benefits that the Ultra 5 cannot match. The i7-1270P also sits at the 76th percentile of all CPUs versus the Ultra 5’s 75th, indicating it remains competitive in the broader market context.

The decision hinges on workload type. The Ultra 5 238V is the superior all-rounder for creative professionals, developers, and users who value modern efficiency (17W TDP versus 28W). The i7-1270P is a specialist for integer-heavy tasks where its core count shines. Neither chip is universally better—the data shows they serve different masters.

FAQ

Q: Which CPU has better multi-core performance?

A: The Intel Core Ultra 5 238V wins all Cinebench multi-core tests. In Cinebench R23 multi-core, it scores 15645 versus the i7-1270P’s 13938, a 10.9% advantage. This pattern repeats in R15 (1576 vs 1404) and R20 (6570 vs 5853).

Q: How do the two chips compare in single-core workloads?

A: The Ultra 5 238V leads by 10.9% in all Cinebench single-core tests. It posts 2208 in R23 single-core versus 1967 for the i7-1270P, and 927 versus 826 in R20 single-core. PassMark single-thread scores confirm this: 3890 versus 3354, a 13.8% gap.

Q: Are there any workloads where the i7-1270P is faster?

A: Yes, two specific areas. The i7-1270P wins PassMark integer math by a staggering 62% (63016 vs 38889) and PassMark data compression by 4.7% (184917 vs 176532). These are the only two tests where it beats the Ultra 5 238V.

Q: What about encryption performance?

A: The Ultra 5 238V is significantly faster. It scores 13072 in PassMark data encryption versus 11276 for the i7-1270P, a 13.7% improvement. This suggests better AES-NI or related instruction efficiency on the newer chip.

Q: Which CPU has more cores and threads?

A: The i7-1270P has 12 cores and 16 threads, while the Ultra 5 238V has 8 cores and 8 threads. Despite having fewer threads, the Ultra 5 still wins most multi-core benchmarks, indicating superior per-core efficiency.

Q: How do their integrated graphics compare?

A: The i7-1270P features Iris Xe 96EU, while the Ultra 5 238V uses Arc 130V. The benchmark data does not include graphics tests, so a direct comparison cannot be made from this dataset, but the newer Arc brand suggests a generational shift.

Specification Differences

The two processors diverge significantly in their core specifications. The i7-1270P uses a 12-core, 16-thread design based on Alder Lake architecture, with a base clock of 2.20 GHz and a boost clock of 4.80 GHz. The Ultra 5 238V uses a leaner 8-core, 8-thread configuration on Lunar Lake architecture, with a base clock of 2.10 GHz and a boost of 4.70 GHz. Despite lower clock speeds, the Ultra 5’s newer architecture wins benchmarks.

The manufacturing process is a major differentiator: the i7-1270P uses Intel’s 10nm node with a 217 mm² die size, while the Ultra 5 238V uses TSMC’s 3nm process. This explains the massive TDP difference—28W for the i7-1270P versus 17W for the Ultra 5 238V. Cache layouts also differ: the i7-1270P has 80 KB L1 per core, 1.25 MB L2 per core, and 18 MB shared L3, while the Ultra 5 238V has 192 KB L1 per core, 2.5 MB L2 per core, and only 8 MB shared L3. The Ultra 5 compensates with larger per-core caches, but its total L3 is less than half.

Socket compatibility is distinct: the i7-1270P uses Intel BGA 1744, while the Ultra 5 238V uses Intel BGA 2833. PCIe support also differs—the i7-1270P offers Gen 4 with 20 CPU lanes, while the Ultra 5 238V offers Gen 5 with only 4 CPU lanes. Memory support shows the i7-1270P officially supporting DDR4 and DDR5, while the Ultra 5 238V’s support is listed as dependent on motherboard configuration. Both use dual-channel memory buses, and neither supports ECC. The Ultra 5 238V was released on 2024-09-23, over two years after the i7-1270P’s 2022-02-22 launch.

Head-to-Head Benchmarks

The Ultra 5 238V dominates the head-to-head results, winning 15 of 17 tests. Its victories span every Cinebench iteration: R15 multi-core (1576 vs 1404, -10.9% delta), R15 single-core (222 vs 198, -10.8%), R20 multi-core (6570 vs 5853, -10.9%), R20 single-core (927 vs 826, -10.9%), R23 multi-core (15645 vs 13938, -10.9%), and R23 single-core (2208 vs 1967, -10.9%). The consistency of the 10.9% delta across all Cinebench tests suggests a uniform architectural efficiency gain rather than workload-specific optimization.

The Ultra 5’s biggest wins come in PassMark extended instructions, where it scores 15377 versus 10575—a 31.2% advantage—and PassMark find prime numbers, where it more than doubles the i7-1270P (174 vs 66, a 62.1% delta). Floating-point math also favors the Ultra 5 by 18.8% (53160 vs 43168), and physics by 27.6% (1546 vs 1120). Even in random string sorting, the Ultra 5 wins by 4.8% (21585 vs 20546), and in PassMark multithread by 7.9% (18407 vs 16957).

The i7-1270P’s two wins are both dramatic. Its 62% lead in integer math (63016 vs 38889) is the largest margin in any test, reflecting the benefit of 12 physical cores over 8. Its data compression win (184917 vs 176532) is narrower at 4.7%, but still meaningful for archiving tasks. These two victories show that raw core count can still overcome architectural disadvantages in specific integer-bound workloads.

Architecture Differences

The architectural divide is generational. The i7-1270P is built on Intel’s Alder Lake-P architecture, a hybrid design that combines performance and efficiency cores, fabricated on Intel’s 10nm process. It offers 12 cores with 16 threads via Hyper-Threading, with a die size of 217 mm². The Ultra 5 238V uses Lunar Lake, Intel’s second-generation Core Ultra design, fabricated by TSMC on a 3nm node—a significant process shrink that explains its lower 17W TDP despite newer features.

Cache hierarchies reveal differing design priorities. The i7-1270P allocates more total L3 cache (18 MB shared) but smaller per-core L1 (80 KB) and L2 (1.25 MB). The Ultra 5 238V inverts this: larger per-core L1 (192 KB) and L2 (2.5 MB) but only 8 MB shared L3. This suggests the Ultra 5 relies on faster per-core access patterns rather than large shared pools, which may explain its superior single-thread performance. The i7-1270P’s larger L3 likely benefits multi-threaded workloads that share data.

PCIe capabilities diverge sharply. The i7-1270P provides 20 Gen 4 lanes from the CPU, enabling ample bandwidth for discrete GPUs and NVMe drives. The Ultra 5 238V offers only 4 Gen 5 lanes—faster per-lane but fewer total, potentially limiting expansion options. Integrated graphics also differ: the i7-1270P uses Iris Xe 96EU, while the Ultra 5 238V uses Arc 130V, representing a generational leap in GPU architecture. Both chips are unlocked for overclocking (multiplier unlocked: false) and target the mobile segment.

The release timeline is telling: the i7-1270P launched on 2022-02-22, while the Ultra 5 238V arrived on 2024-09-23. The 2.5-year gap allowed Intel to shift from its own 10nm foundry to TSMC’s 3nm, a move that yields better performance-per-watt. The benchmark data confirms this: the Ultra 5 achieves higher scores across nearly all tests while consuming 39% less power (17W vs 28W). This efficiency gain is the defining architectural difference between the two processors.
