Intel Core i7-12650HX vs Intel Core i7-12800H Comparison

The Verdict

The benchmark data tells a clear story: these two 14-core, 20-thread Alder Lake mobile processors are tuned for different priorities. The Intel Core i7-12800H is the more consistent all-round performer, winning 12 of the 17 recorded head-to-head tests. The Intel Core i7-12650HX, however, holds decisive victories in the most demanding modern rendering workloads and in raw single-thread tests. If your primary workload is Cinebench R23, especially the single-core variant, the 12650HX is the clear choice. If you need balanced performance across a wider range of tasks, from data compression to physics simulations, the 12800H is the safer pick. The 12650HX is also the only one of the two with an unlocked multiplier, which matters for users who intend to push clock speeds manually, though the 12800H already ships with a higher base clock of 2.40 GHz versus 2000.00 MHz and a higher boost clock of 4.80 GHz versus 4.70 GHz.

Q: Which CPU has a higher average benchmark score?

A: The 12800H has an average benchmark score of 32121, placing it alongside the Intel Core i5-14400 (0% delta), Intel Core i7-13705H (+0.1%), and Intel Core i5-14450HX (+0.3%). The 12650HX averages 31290, sitting near the Intel Core 9 273PTE (+0.5%), Intel Core Ultra 3 205 (-0.6%), and Intel Core 7 240H (-0.6%). Both sit in the 82nd percentile of all CPUs.

Architecture Differences

Both processors are built on Intel's Alder Lake architecture and share the same 10 nm process node at Intel's foundry. The core configuration is identical on paper: 14 cores and 20 threads, with a hybrid layout of performance and efficiency cores. The cache hierarchy matches as well, with 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The die size is nearly the same, 215 mm² for the 12650HX and 217 mm² for the 12800H.

The architectural split emerges in the platform details. The 12650HX belongs to the Alder Lake-HX family, which is the higher-power, desktop-derived mobile variant. This is reflected in its 55 watt TDP, its PCIe Gen 5 support with 20 CPU lanes, and its unlocked multiplier. The 12800H belongs to the Alder Lake-H family, a more traditional mobile processor line, with a 45 watt TDP, PCIe Gen 4 support with 20 CPU lanes, and a locked multiplier. The integrated graphics also differ: the 12650HX carries UHD Graphics 770, while the 12800H carries Iris Xe 96EU. Both support DDR4 and DDR5 memory in dual-channel configuration, and neither supports ECC memory.

The release timeline also differs. The 12650HX has a recorded release date of 2022-05-09, while the 12800H has no release date listed in the database. Both are marked as Active in production status and target the mobile market segment.

Specification Differences

The two CPUs differ in several key specification fields. The base clock is 2000.00 MHz for the 12650HX and 2.40 GHz for the 12800H, a difference of 400 MHz in favor of the 12800H. The boost clock is 4.70 GHz for the 12650HX and 4.80 GHz for the 12800H, again favoring the 12800H by 100 MHz. TDP differs significantly: 55 watts for the 12650HX versus 45 watts for the 12800H. The sockets are different, BGA 1964 versus BGA 1744. The codenames differ, Alder Lake-HX versus Alder Lake-H. PCIe support differs: Gen 5 for the 12650HX, Gen 4 for the 12800H. The integrated graphics differ: UHD Graphics 770 versus Iris Xe 96EU. The multiplier is unlocked on the 12650HX and locked on the 12800H. Die size differs slightly, 215 mm² versus 217 mm². The 12800H has a part number, SRLD2, while the 12650HX does not list one. Neither CPU has a recorded launch MSRP, and neither supports ECC memory.

Head-to-Head Benchmarks

The Cinebench results are the most striking part of this comparison because they point in opposite directions depending on the version of the test. In Cinebench R15 multi-core, the 12800H leads with 2222 versus 1919, a 13.6% advantage. In Cinebench R20 multi-core, the 12800H leads again with 8463 versus 7998, a 5.5% advantage. But in Cinebench R23 multi-core, the 12650HX reverses the trend with a commanding 19043 versus 15283, a 24.6% lead. The single-core results are similarly inconsistent. The 12650HX wins Cinebench R15 single-core by 1.9% (270 versus 265) and Cinebench R23 single-core by a massive 47% (2688 versus 1828). The 12800H wins Cinebench R20 single-core by 5.5% (1194 versus 1128).

The PassMark suite is more one-sided. The 12800H wins data compression (273247 versus 266700, 2.4% lead), data encryption (16234 versus 15325, 5.6% lead), extended instructions (16408 versus 15856, 3.4% lead), find prime numbers (102 versus 74, 27.5% lead), floating point math (60961 versus 58426, 4.2% lead), integer math (86488 versus 81810, 5.4% lead), multithread (24346 versus 22573, 7.3% lead), physics (1682 versus 1152, 31.5% lead), and random string sorting (30453 versus 29692, 2.5% lead). The 12650HX wins only PassMark single-thread (3637 versus 3440, 5.7% lead), which appears twice in the record.

The physics test deserves special attention. The 12800H's 31.5% lead there is its largest single margin, second only to the 12650HX's 47% lead in Cinebench R23 single-core. The 47% delta in R23 single-core is the largest delta in the entire head-to-head set, and it dwarfs the 12800H's wins in other categories.

Where Each One Wins

The 12650HX wins 5 of the 17 recorded head-to-head tests. Its victories are concentrated in Cinebench R23 multi-core (19043 versus 15283, 24.6% lead), Cinebench R23 single-core (2688 versus 1828, 47% lead), Cinebench R15 single-core (270 versus 265, 1.9% lead), and PassMark single-thread (3637 versus 3440, 5.7% lead). For rendering workloads that scale with the latest Cinebench version, the 12650HX is the 12650HX is the 12650HX wins 12650H, the 12650HX 12800H single-core R23, single-core R23 single-core 12800HX is the 47% lead by a wide 24.6% in R23 multi-core and 47 in R23 single-core, this is the processor with the higher boost clock of 4.70 GHz and the unlocked multiplier, though its base clock of 2000.00 MHz is lower than the competitor's 2.40 GHz.

The 12800H wins 12 of 17 tests, including every PassMark test except single-thread. Its leads range from 2.4% in data compression to 31.5% in physics. It also wins Cinebench R15 multi-core (2222 versus 1919), Cinebench R20 multi-core (8463 versus 7998), and Cinebench R20 single-core (1194 versus 1128). The 12800H's strongest category is physics, where its 1682 score versus 1152 gives it a 31.5% advantage, and prime number finding, where its 102 versus 74 is a 27.5% lead. With its higher base and boost clocks, 2.40 GHz and 4.80 GHz respectively, and its lower 45 watt TDP, the 12800H is the more efficient and broadly capable option in this pairing. The average benchmark scores reflect this, with the 12800H at 32121 and the 12650HX at 31290, a difference of 831 points. The 12650HX's higher TDP of 55 watts does not translate into a general performance advantage in the recorded data, only in the specific Cinebench R23 and single-thread tests. For users who prioritize the latest Cinebench rendering workloads and raw single-thread speed, the 12650HX is the pick. For everything else, the 12800H is the better choice.
