Intel Core i7-1270P vs Intel Core i9-11900F Comparison

Head-to-Head Benchmarks

The benchmark data paints a decisive picture. The Intel Core i9-11900F wins 15 of the 17 recorded head-to-head comparisons, with the Intel Core i7-1270P claiming only two victories. This is not a subtle margin; in several workloads the desktop chip is dramatically ahead.

The Cinebench suite shows the most consistent dominance. Across all three versions of the render benchmark (R15, R20, and R23), the i9-11900F leads by exactly 34.6% in both single-core and multi-core tests. In Cinebench R23 multi-core, the i9-11900F scores 18,759 versus 13,938 for the i7-1270P. The single-core gap is equally stark: 2,648 versus 1,967 in R23, and 1,112 versus 826 in R20. These are not marginal differences; they indicate a fundamental performance tier separation.

The PassMark suite reinforces the trend. Data compression shows the i9-11900F at 280,847 versus 184,917, a 51.9% lead. Random string sorting is even more lopsided at 58.3% (32,520 versus 20,546). Extended instructions, a test that measures AVX and other vector workloads, shows the largest delta of the entire comparison at 83.9% (19,443 versus 10,575). Integer math favors the i9-11900F by 32.9% (83,718 versus 63,016), and multithread performance is 30.4% higher (22,115 versus 16,957).

The i7-1270P does not go entirely unanswered. In PassMark find prime numbers, it wins by 7.6% (66 versus 61). In PassMark physics, the mobile chip leads by 15.3% (1,120 versus 949). These two wins hint at different architectural strengths, but they are isolated islands in a sea of i9-11900F superiority.

Floating point math is closer than most other tests, with the i9-11900F ahead by just 12.5% (48,562 versus 43,168). Data encryption shows a 20.9% edge for the desktop part (13,636 versus 11,276). The narrowest victory for the i9-11900F comes in PassMark single-thread, where it leads by only 1.8% (3,413 versus 3,354). That single-thread margin is surprisingly small given the 34.3% gap in Cinebench R15 single-core, suggesting the two chips are closer in lightly threaded scalar work than the render benchmarks imply.

The overall average benchmark scores confirm the hierarchy. The i9-11900F posts an average of 23,254 across all recorded tests, placing it in the 76th percentile of all CPUs. The i7-1270P averages 22,502, also in the 76th percentile. The 752-point average gap represents a 3.3% difference in overall performance, but the head-to-head data shows that gap is unevenly distributed, with the i9-11900F winning by double digits in most tests and losing by smaller margins in the two it drops.

Q: Are these CPUs in the same performance percentile overall?

A: Yes. Both are in the 76th percentile of all CPUs. The i9-11900F has an average benchmark score of 23,254, while the i7-1270P averages 22,502.

Q: Which chip has more cores?

A: The i7-1270P has 12 cores versus 8 for the i9-11900F. However, both have 16 threads, and the i9-11900F still wins the vast majority of threaded benchmarks.

Architecture Differences

The two processors come from different Intel generations and use fundamentally different designs. The i9-11900F is built on Rocket Lake, Intel's 14 nm process, with a die size of 276 mm². The i7-1270P uses Alder Lake-P, manufactured on a 10 nm process, with a smaller die at 217 mm². Both are Intel parts, but the process node difference is substantial: 14 nm versus 10 nm.

Core counts diverge significantly. The i9-11900F packs 8 cores and 16 threads, all of them identical high-performance cores. The i7-1270P has 12 cores and 16 threads, but those cores are split between performance and efficiency types (the Alder Lake hybrid design). This explains why the i7-1270P can have more physical cores yet still lose in most multi-threaded tests: not all of its cores are created equal.

Cache hierarchies also differ. Both have 80 KB of L1 cache per core, but the L2 cache is 512 KB per core on the i9-11900F versus 1.25 MB per core on the i7-1270P. The L3 cache is 16 MB shared on the Rocket Lake part and 18 MB shared on the Alder Lake part. The larger per-core L2 on the i7-1270P likely contributes to its wins in prime number calculation and physics tests.

Memory support separates the two as well. The i9-11900F supports only DDR4, while the i7-1270P supports both DDR4 and DDR5. Both use dual-channel memory buses. The i9-11900F has a recorded memory bandwidth of 51.2 GB/s; no bandwidth figure is recorded for the i7-1270P. Neither chip supports ECC memory.

PCIe capabilities are identical: Gen 4 with 20 lanes (CPU only) for both. Integrated graphics are absent on the i9-11900F, which requires a discrete GPU. The i7-1270P includes Iris Xe 96EU integrated graphics, making it a complete mobile package.

The market positioning is clear from the sockets. The i9-11900F uses Intel Socket 1200 for desktop builds, while the i7-1270P uses Intel BGA 1744, a soldered mobile socket. The i9-11900F is marked end-of-life, while the i7-1270P remains active in production.

Specification Differences

The most obvious specification gap is core count: 8 cores for the i9-11900F versus 12 for the i7-1270P. Thread counts are equal at 16. Base clocks differ, with the i9-11900F at 2.50 GHz and the i7-1270P at 2.20 GHz. Boost clocks also favor the desktop part: 5.20 GHz versus 4.80 GHz.

Thermal design power is a major separator. The i9-11900F draws 65 W, while the i7-1270P is rated at only 28 W. This explains the performance gap in sustained workloads, as the desktop chip has more than twice the thermal headroom.

Process node and die size differ as noted: 14 nm and 276 mm² for the i9-11900F, 10 nm and 217 mm² for the i7-1270P. The i7-1270P has a larger L2 cache per core (1.25 MB versus 512 KB) and a slightly larger L3 cache (18 MB versus 16 MB). L1 cache is identical at 80 KB per core.

Memory support is another differentiator. The i9-11900F is limited to DDR4, while the i7-1270P supports DDR4 and DDR5. The i9-11900F has a recorded memory bandwidth of 51.2 GB/s; the i7-1270P has no bandwidth figure in the database. ECC is unsupported on both.

Integrated graphics are exclusive to the i7-1270P, which carries Iris Xe 96EU. The i9-11900F has no integrated graphics. Sockets differ as expected: Socket 1200 for the desktop chip, BGA 1744 for the mobile chip.

Release dates are roughly a year apart: the i9-11900F launched on March 15, 2021, and the i7-1270P on February 22, 2022. The i9-11900F has a recorded launch MSRP of $422, while the i7-1270P has no MSRP listed. Both CPUs have locked multipliers, so neither supports easy overclocking.

The Verdict

The data supports a clear split decision based on use case. For anyone building a desktop system that prioritizes raw compute throughput, the Intel Core i9-11900F is the unambiguous choice. It wins 15 of 17 head-to-head benchmarks, often by margins of 30% to 80%. The 34.6% lead across all Cinebench tests, both single and multi-core, shows that this chip is simply in a higher performance tier for rendering and content creation workloads. The 83.9% advantage in extended instructions makes it particularly strong for AVX-heavy scientific or engineering applications.

The i7-1270P is not without merit. Its 28 W TDP makes it suitable for thin-and-light laptops where power efficiency is paramount. The 12-core hybrid design with efficiency cores gives it an edge in specific workloads like prime number calculation (7.6% faster) and physics simulation (15.3% faster). The integrated Iris Xe 96EU graphics mean it can operate without a discrete GPU, which is impossible for the i9-11900F. For mobile users who need a capable CPU in a portable chassis, the i7-1270P is the only viable option between the two, as the i9-11900F requires a desktop motherboard and a separate graphics card.

The overall average scores are close (23,254 versus 22,502), but that masks the distribution. The i9-11900F dominates in most tests, while the i7-1270P wins only the two narrowest categories. The percentile rankings are identical at 76, but the head-to-head data shows the i9-11900F is the stronger all-around performer.

The decision should come down to platform and power constraints. Desktop builders with access to a discrete GPU and a Socket 1200 motherboard should take the i9-11900F without hesitation. Its 65 W TDP is modest for the performance it delivers, and the 5.20 GHz boost clock gives it excellent single-thread responsiveness. Mobile users with strict power budgets and no desire for a discrete GPU should choose the i7-1270P, accepting lower multi-core performance in exchange for portability and integrated graphics. The i7-1270P is also the only one of the two still in active production, which matters for long-term availability.
