Intel Core i7-12700H vs Intel Core i9-11900KF Comparison

Head-to-Head Benchmarks

The recorded data presents a surprisingly close contest between the Intel Core i7-12700H and the Intel Core i9-11900KF, with the latter edging ahead in total wins by a narrow 12 to 11 margin. However, the scale of those wins varies dramatically depending on the workload, revealing two processors with sharply different personalities.

The clearest victory for the Core i9-11900KF appears in single-threaded performance. In Cinebench R23 single-core, the desktop chip scores 2941 against the mobile chip's 1782, a 39.4% advantage. Similarly, in Cinebench R15 single-core, the i9-11900KF leads with 296 versus 256, a 13.5% gap. Even in 3DMark single-thread, the i9 takes 1026 over 949, a 7.5% lead. These results align with the i9's significantly higher boost clock of 5.30 GHz compared to the i7's 4.70 GHz, and its older but higher-clocked architecture appears to deliver in lightly threaded tasks.

The story inverts for several multithreaded workloads. The i7-12700H wins Cinebench R15 multicore by a substantial 24%, scoring 2604.6 against 2100. The i7 also takes Cinebench R20 multicore, though narrowly, at 8921 versus 8751, a 1.9% edge. Yet in Cinebench R23 multicore, the i9-11900KF reasserts itself with a commanding 20838 versus 16307.5, a 21.7% lead. This inconsistency across Cinebench versions is curious; the database shows the i7 winning the older R15 and R20 tests while losing the newer R23 test by a wide margin.

PassMark results further complicate the picture. The i7-12700H wins passmark_multithread with 25615 against 24708, a 3.7% margin. It also takes passmark_physics by a stunning 46.2%, scoring 1512 versus 1034, and passmark_find_prime_numbers by 42.4% (94 versus 66). Floating-point math also favors the i7, with 65075 versus 52640, a 23.6% advantage. Integer math is nearly tied, with the i7 ahead by just 1.2% (90106 versus 89023).

The i9-11900KF counters in other PassMark subtests. It wins data compression 325688 versus 300594, a 7.7% edge, and extended instructions 22703 versus 17886, a 21.2% margin. Random string sorting goes to the i9 at 37383 versus 33449, a 10.5% lead. Data encryption is the i7's territory, however, with 17575 versus 15623, a 12.5% win.

The 3DMark suite is almost entirely the i9's domain. At 16 threads, the i9 leads 8335 to 6460, a 22.5% gap. At 8 threads, the difference grows to 25.8%, with 6671 versus 4951. Even at 2 threads, the i9 maintains a 9.4% advantage (2005 versus 1817). The only single-thread benchmark where the i7 wins is passmark_single_thread, and the margin is razor-thin: 3535 versus 3527, just 0.2%.

Interpreting these results requires care. The i9-11900KF is a desktop processor with an unlocked multiplier, a 125 W TDP, and a 5.30 GHz boost clock. The i7-12700H is a mobile chip with a 45 W TDP and a hybrid Alder Lake design. Yet the i7 still manages to win 11 of the 23 recorded head-to-head comparisons, often in math-heavy or encryption workloads. The data suggests the i7's 14 cores and 20 threads provide real muscle in parallel tasks, while the i9's higher clock speeds dominate in latency-sensitive or lightly threaded scenarios.

Architecture Differences

The two processors come from different Intel generations and use fundamentally different designs. The i7-12700H is built on Alder Lake architecture using a 10 nm process node, while the i9-11900KF uses Rocket Lake architecture on a 14 nm node. The process advantage translates into a smaller die size for the i7 at 217 mm², compared to the i9's 276 mm².

Core configuration differs substantially. The i7-12700H packs 14 cores and 20 threads, while the i9-11900KF has 8 cores and 16 threads. This core advantage likely explains the i7's wins in heavily parallel workloads like passmark_physics and floating-point math. Cache hierarchies also diverge: both share 80 KB of L1 per core, but the i7 has 1.25 MB of L2 per core versus 512 KB for the i9, and the i7's L3 cache is 24 MB shared versus 16 MB for the i9.

Memory support marks another clear split. The i7-12700H supports both DDR4 and DDR5 memory, while the i9-11900KF is limited to DDR4. The i9 does list a memory bandwidth of 51.2 GB/s in the database, a figure not recorded for the i7. Both processors use dual-channel memory buses and provide Gen 4 PCIe with 20 lanes.

The i7-12700H includes integrated graphics in the form of Iris Xe 96EU, whereas the i9-11900KF has no integrated graphics at all, consistent with its "KF" designation. The i7 is a mobile processor using the Intel BGA 1744 socket, while the i9 is a desktop part on Intel Socket 1200. The i9 also carries an unlocked multiplier, reflecting its desktop overclocking heritage, while the i7 is locked.

Production status differs as well: the i7 is marked as active, while the i9 is end-of-life. The i9's release date is recorded as March 15, 2021, and its launch MSRP is $513. The i7's release date and launch MSRP are not recorded in the database.

Specification Differences

The core count is the most obvious differentiator: 14 cores for the i7-12700H versus 8 for the i9-11900KF. Thread counts follow at 20 versus 16. Base clocks favor the i9 at 3.50 GHz against the i7's 2.30 GHz, and boost clocks also favor the i9 at 5.30 GHz versus 4.70 GHz.

Thermal design power shows the expected desktop versus mobile split, with the i9 rated at 125 W and the i7 at 45 W. Process nodes differ, 10 nm for the i7 and 14 nm for the i9, as do die sizes at 217 mm² and 276 mm² respectively. The L2 cache per core is 1.25 MB for the i7 and 512 KB for the i9, while shared L3 is 24 MB for the i7 and 16 MB for the i9.

Memory support is broader on the i7, which accepts both DDR4 and DDR5, while the i9 supports only DDR4. The i9 lists a memory bandwidth of 51.2 GB/s, a field not recorded for the i7. Both use dual-channel memory buses and offer Gen 4 PCIe with 20 lanes, so those two fields are identical.

Integrated graphics are present on the i7 (Iris Xe 96EU) and absent on the i9. Sockets differ, BGA 1744 for the mobile i7 and Socket 1200 for the desktop i9. The multiplier is unlocked on the i9 but locked on the i7. Market segments are mobile versus desktop. Production status is active for the i7 and end-of-life for the i9. The i9 has a recorded release date and launch MSRP of $513, while neither is recorded for the i7. Part numbers also differ, SRLD1 for the i7 and SRKNF for the i9.

The Verdict

The data does not crown a single winner. Instead, it describes two processors optimized for different environments. The i9-11900KF takes the majority of head-to-head wins, 12 to 11, and dominates in single-threaded and lightly threaded tasks. Its 39.4% lead in Cinebench R23 single-core and 21.7% lead in Cinebench R23 multicore are decisive. For workloads that depend on high clock speeds, the i9 is clearly the stronger part.

The i7-12700H, despite being a mobile chip with a 45 W TDP, wins the average benchmark score comparison at 26717 versus 26212. It also outperforms the i9 in several math-heavy and encryption tasks, including a 46.2% margin in passmark_physics and a 42.4% edge in passmark_find_prime_numbers. Its 14 cores and 20 threads give it a structural advantage in parallel throughput that the i9 cannot always overcome.

The i9's unlocked multiplier and desktop socket make it the choice for users who want to push clocks further, while the i7's active production status and integrated graphics offer a more complete package for a mobile system. The i9 is end-of-life, which may matter for long-term availability, while the i7 remains active. Neither part is clearly superior; the right pick depends entirely on whether the workload favors raw clock speed or parallel core count.

Where Each One Wins

The i9-11900KF wins in scenarios that reward high boost clocks and strong single-thread performance. Cinebench R23 single-core, where it leads by 39.4%, is a prime example. The i9 also wins every recorded 3DMark test, from single-thread (1026 versus 949) to 16-thread (8335 versus 6460). Data compression, extended instructions, and random string sorting also favor the i9, with margins of 7.7%, 21.2%, and 10.5% respectively. Users running lightly threaded applications, legacy single-threaded games, or compression workloads would see the i9's strengths emerge.

The i7-12700H wins in parallel and math-intensive workloads. Its 46.2% lead in passmark_physics and 42.4% lead in passmark_find_prime_numbers are the largest margins recorded for either processor. Floating-point math also goes to the i7 by 23.6%, and data encryption by 12.5%. The i7 edges out the i9 in Cinebench R15 multicore by 24% and Cinebench R20 multicore by 1.9%, though it loses Cinebench R23 multicore by 21.7%. In passmark_multithread, the i7 leads by 3.7%, and in passmark_single_thread it wins by a negligible 0.2%. The i7 also wins passmark_integer_math by 1.2%, a nearly tied result that still favors the mobile chip.

For users who prioritize multithreaded rendering in older Cinebench versions, physics calculations, encryption, or floating-point workloads, the i7-12700H holds the advantage. For those who need maximum single-thread speed, higher boost clocks, or consistent wins across 3DMark, the i9-11900KF is the data-backed choice. The two processors are close in overall average score, but their strengths are distributed unevenly across the benchmark suite, and the correct selection depends on the specific application mix.
