Intel Core 7 250H vs Intel Core i7-12700K Comparison

The Intel Core 7 250H and Intel Core i7-12700K are both 10 nm Intel parts, but they target entirely different segments: one is a 45 W mobile processor in a BGA package, and the other is a 125 W desktop chip on Socket 1700. Benchmark data shows the desktop i7-12700K dominates in multi-threaded workloads, winning 12 of 17 head-to-head tests, while the mobile 250H counters with a handful of single-thread and physics victories. The average benchmark scores are close — 35728 for the 250H versus 35287 for the 12700K — but that figure masks a wide performance gap in sustained all-core tasks, where the desktop part’s higher TDP and larger L3 cache prove decisive. The 250H’s wins are narrower, with its best margin being a 9.6% lead in Cinebench R15 single-core, whereas the 12700K regularly posts double-digit deltas of 20% or more in multi-core tests.

The Verdict

The data splits this cleanly by use case. The Intel Core i7-12700K is the pick for anyone running heavily threaded workloads like video rendering, data compression, or extended instruction sets; it beats the 250H by 16.3% in Cinebench R23 multi-core, 32.1% in PassMark data compression, and 40% in extended instructions. Its 12 cores and 20 threads, paired with a 125 W TDP, deliver consistently higher throughput in every multi-core benchmark except one narrow physics test. The 250H, meanwhile, is the choice for single-thread responsiveness and mobile integration — it wins Cinebench R23 single-core by 4.4% and PassMark single-thread by 3.4%, and it does so inside a 45 W envelope with a 5.40 GHz boost clock. The desktop chip also carries a lower launch MSRP of $409 versus the 250H’s $502, though pricing is not a performance metric.

For a laptop buyer, the 250H is the only realistic option of the two due to its mobile socket, and its single-core edge means snappy everyday use. For a desktop builder, the 12700K is the clear winner — it is cheaper at launch, has an unlocked multiplier, and crushes the mobile part in all-core workloads. The 250H’s 85th percentile versus the 12700K’s 84th percentile among all CPUs is essentially a tie, but that ranking reflects average score, not the lopsided multi-core results where the desktop part excels. There is no scenario in the data where the 250H outperforms the 12700K in a demanding multi-threaded application, so the verdict is: desktop users take the 12700K, mobile users take the 250H, and neither is a substitute for the other.

Architecture Differences

The two chips share a 10 nm process node and Intel as the foundry, but diverge in nearly every other architectural detail. The 250H is built on Raptor Lake-H, a Raptor Lake Refresh generation part, with 14 cores and 20 threads; the 12700K is Alder Lake-S, a 12th-generation Core i7, with 12 cores and 20 threads. Both have 20 threads, but the 250H achieves that with two more physical cores, suggesting a different hybrid core arrangement. The 250H’s cache layout is 80 KB L1 per core and 2 MB L2 per core, with 24 MB shared L3; the 12700K has the same 80 KB L1 per core but only 1.25 MB L2 per core, compensated by a slightly larger 25 MB shared L3. That extra 1 MB of L3 on the desktop part likely contributes to its multi-core dominance.

Clock speeds tell a similar story. The 250H has a 2.50 GHz base and 5.40 GHz boost, while the 12700K runs a 3.60 GHz base and 5.00 GHz boost. The mobile part boosts higher, explaining its single-core wins, but the desktop part’s higher base clock and 125 W TDP — versus 45 W — sustain all-core performance far better. The 12700K also has a larger die at 215 mm², though the 250H’s die size is not listed. Memory support is identical: both support DDR4 and DDR5 in dual-channel mode, and neither supports ECC. PCIe lanes differ significantly: the 250H offers Gen 5 with 8 CPU lanes, while the 12700K offers Gen 4 with 20 CPU lanes — more lanes for desktop expansion but an older standard. Integrated graphics also differ: the 250H uses Iris Xe Graphics with 96 execution units, while the 12700K has UHD Graphics 770. The 12700K has an unlocked multiplier; the 250H does not. The 250H was released on 2024-12-17, while the 12700K came out on 2021-11-03.

Where Each One Wins

The 250H wins in single-threaded tests and one physics workload. It takes Cinebench R15 single-core by 9.6% (298 vs 272), Cinebench R23 single-core by 4.4% (1931 vs 1850.5), PassMark single-thread by 3.4% (4148 vs 4013), and PassMark physics by 1.9% (1824 vs 1790). These wins are all modest, under 10%, and point to a processor that feels snappier in lightly threaded tasks like web browsing, office work, or older games that rely on a single core. The 250H’s 5.40 GHz boost clock is the likely driver, and its mobile TDP means it can deliver this performance in a laptop chassis.

The 12700K wins everywhere else, and by much larger margins. Its multi-core victories include Cinebench R20 multi-core at 12229 vs 9697 (a 20.7% lead), Cinebench R23 multi-core at 19784 vs 16561 (16.3% ahead), and Cinebench R15 multi-core at 3325 vs 3147 (5.4% ahead). In PassMark suite tests, the desktop part leads by 32.1% in data compression (446595 vs 303269), 22.2% in data encryption (23408 vs 18206), 40% in extended instructions (28885 vs 17318), 26.1% in floating-point math (88035 vs 65094), 13.3% in integer math (114264 vs 99100), 21.4% in multithread (34404 vs 27030), and 25.5% in random string sorting (45805 vs 34136). It also wins the only 3DMark tests listed, though those are not in the head-to-head table. The 12700K’s 20 threads match the 250H, but its higher base clock and larger L3 cache give it a decisive edge in sustained loads.

Head-to-Head Benchmarks

The biggest win for the 250H is Cinebench R15 single-core, where it scores 298 against the 12700K’s 272, a 9.6% lead. That is the largest margin in either direction for the mobile chip. The 250H also takes Cinebench R23 single-core with 1931 vs 1850.5 (4.4% ahead) and PassMark single-thread with 4148 vs 4013 (3.4% ahead). In PassMark physics, the 250H edges out the 12700K by 1.9% (1824 vs 1790), a narrow but notable win for a mobile part. These victories are all in single-thread or lightly threaded workloads, reinforcing that the 250H’s 5.40 GHz boost clock gives it a real responsiveness advantage.

The 12700K’s wins are far more decisive. Its largest margin is in PassMark extended instructions, where it scores 28885 versus 17318, a 40% lead. That is a massive gap for a workload that exercises AVX and similar instruction sets. In PassMark data compression, the 12700K posts 446595 vs 303269, a 32.1% advantage, and in floating-point math it leads 88035 vs 65094, a 26.1% gap.

The 12700K also wins Cinebench R20 multi-core by 20.7% (12229 vs 9697) and PassMark multithread by 21.4% (34404 vs 27030). Cinebench R23 multi-core shows a 16.3% lead (19784 vs 16561), integer math is 13.3% ahead (114264 vs 99100), and find prime numbers goes to the 12700K by 7% (114 vs 106). Even the closest multi-core test, Cinebench R15 multi-core, favors the desktop part at 3325 vs 3147, a 5.4% win. The 12700K wins 12 of 17 head-to-head tests, and its losses are all by single-digit percentages, while its wins often exceed 20%. The data is unambiguous: in any throughput-focused task, the desktop i7-12700K is the stronger processor, while the mobile 250H is the better single-thread performer.
