Intel Core i7-12700H vs Intel Core i7-1280P Comparison

The Intel Core i7-12700H and Intel Core i7-1280P are both 14-core Alder Lake mobile processors built on the same 10 nm Intel process, but they are engineered for different laptop classes. The 12700H (Alder Lake-H) carries a 45 W TDP and is aimed at performance notebooks, while the 1280P (Alder Lake-P) is a 28 W part designed for thinner, more portable systems. Despite sharing core counts, cache sizes, and integrated graphics, benchmark data shows the H-series chip holds a commanding lead across every single measured workload, making the choice between them largely a question of chassis thermal headroom versus raw performance.

FAQ

Q: Which processor has more cores and threads?

A: Both the Intel Core i7-12700H and the Intel Core i7-1280P have identical core and thread counts: 14 cores and 20 threads each.

Q: How do their base and boost clocks compare?

A: The i7-12700H has a base clock of 2.30 GHz and a boost clock of 4.70 GHz. The i7-1280P has a much lower base clock of 1800.00 MHz (1.80 GHz) but a slightly higher boost clock of 4.80 GHz.

Q: What is the main difference in their thermal design power?

A: The i7-12700H is rated at a TDP of 45 W, while the i7-1280P is rated at 28 W. This 17 W difference reflects the 12700H's design for higher sustained performance in larger laptops.

Q: Do they use the same socket and memory support?

A: Yes, both use the Intel BGA 1744 socket and support dual-channel DDR4 and DDR5 memory. They also share the same PCIe Gen 4, 20 Lanes (CPU only) configuration.

Q: Which processor has better integrated graphics?

A: Both processors feature the same Iris Xe 96EU integrated graphics, so there is no difference in GPU capability based on this data.

Q: How many benchmark wins does each processor have in head-to-head testing?

A: The Intel Core i7-12700H wins all 17 head-to-head benchmark comparisons. The Intel Core i7-1280P wins none of them.

Architecture Differences

Both processors are built on Intel's Alder Lake architecture, but they belong to different sub-families: Alder Lake-H for the i7-12700H and Alder Lake-P for the i7-1280P. The die size is identical at 217 mm², and both are manufactured on the same 10 nm process node at Intel's foundry. Cache hierarchies are also the same: 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache.

The critical architectural divergence lies in power delivery and clock behavior. The i7-12700H's 45 W TDP allows it to maintain higher sustained clocks across all cores, which is directly reflected in its superior multi-threaded scores. The i7-1280P, with its 28 W TDP, is binned for lower power consumption, sacrificing base clock (1.80 GHz vs 2.30 GHz) but managing a slightly higher single-core boost at 4.80 GHz compared to the 12700H's 4.70 GHz. Both chips are unlocked, meaning their multipliers cannot be adjusted, and neither supports ECC memory. The part numbers differ (SRLD1 for the 12700H, SRLD5 for the 1280P), and the 1280P has a recorded release date of February 22, 2022, while the 12700H's release date is not listed in the data.

Head-to-Head Benchmarks

The most striking result is in Cinebench R23 multi-core, where the i7-12700H scores 16307.5 against the i7-1280P's 11666, a massive 39.8% advantage. This is the largest single delta in the entire benchmark suite. The gap narrows but remains substantial in Cinebench R20 multi-core (8921 vs 7153, a 24.7% lead) and Cinebench R15 multi-core (2604.6 vs 2112, a 23.3% lead). Single-core performance tells a different story, with much smaller margins: the 12700H leads by 7.6% in Cinebench R15 single-core (256 vs 238) and 7.9% in Cinebench R23 single-core (1782 vs 1651). The Cinebench R20 single-core test shows the widest single-thread gap at 24.8% (1259 vs 1009), which is unusual given the 1280P's higher boost clock.

In PassMark tests, the 12700H dominates across the board. The largest wins come in data compression (300594 vs 220621, a 36.2% lead), random string sorting (33449 vs 24308, a 37.6% lead), and extended instructions (17886 vs 12897, a 38.7% lead). Floating-point math shows a 26.7% advantage (65075 vs 51355), while integer math is closer at 19.4% (90106 vs 75485). The smallest deltas appear in find prime numbers (94 vs 86, a 9.3% lead) and physics (1512 vs 1411, a 7.2% lead). PassMark single-thread scores favor the 12700H by 6.6% (3535 vs 3316), and the multithread score shows a 27% advantage (25615 vs 20168). Data encryption rounds out the suite with a 33.4% lead (17575 vs 13179).

The Verdict

The data is unambiguous: the Intel Core i7-12700H is the superior processor for any workload that benefits from sustained multi-threaded performance. Its 39.8% lead in Cinebench R23 multi-core and 36.2% lead in PassMark data compression indicate that it is not just slightly faster but categorically in a higher performance tier. The i7-1280P, while competitive in single-threaded tasks (within 6.6% to 7.9% in most tests), cannot overcome the 12700H's power advantage in longer, multi-threaded workloads. The 12700H's percentile ranking of 79 versus the 1280P's 78 also reflects its slightly higher standing among all CPUs.

Buyers should choose the i7-12700H if they prioritize performance and are purchasing a laptop with adequate cooling for a 45 W processor. The 1280P makes sense only if the laptop's form factor absolutely requires a 28 W chip, but the performance penalty is severe: you are giving up roughly a quarter to a third of multi-threaded performance in many tests. The 1280P does offer a marginally higher boost clock, but that does not translate into any benchmark victory. For pure computational throughput, the 12700H is the clear winner, with 17 wins out of 17 head-to-head comparisons.

Where Each One Wins

The Intel Core i7-12700H wins in every measured category, but the size of its advantage varies. For users who run heavily threaded applications—video rendering, 3D modeling, software compilation, or scientific computing—the 12700H is the only sensible choice. Its Cinebench R23 multi-core score of 16307.5 versus 11666 means render times will be roughly 40% shorter. Data compression and encryption tasks also show massive gains (36.2% and 33.4% respectively), making it ideal for database work or file archiving.

The i7-1280P's only theoretical advantage is its lower 28 W TDP, which enables thinner, lighter laptops with smaller batteries and quieter cooling. In terms of raw performance, it does not win a single benchmark. Its closest margins are in single-threaded PassMark tests (6.6% behind) and physics (7.2% behind), meaning that for light office work, web browsing, or basic productivity, the 1280P would feel nearly as responsive. However, the 12700H still leads in those tasks, and the 1280P's higher 4.80 GHz boost clock does not result in a single win. For any user who occasionally pushes the CPU with demanding multi-threaded workloads, the 12700H is the definitive pick. The 1280P is only justifiable when the laptop's physical design cannot accommodate a 45 W processor, and the user accepts a 20% to 40% performance deficit across most benchmarks.
