Intel Core 9 270H vs Intel Core i9-12900KF Comparison

The Intel Core i9-12900KF and Intel Core 9 270H both sit at the 91st percentile among all CPUs, with average benchmark scores of 42739 and 42816 respectively — a difference of only 0.2%. That near-tie, however, masks a decisive head-to-head pattern: the 12900KF wins 15 of the 17 shared tests, while the 270H counters with a narrow single-thread advantage in Passmark. The following analysis breaks down where each chip leads and what that means for real workloads.

Head-to-Head Benchmarks

The 12900KF’s largest victory comes in Passmark’s extended instructions test, where it scores 33779 against the 270H’s 21785 — a 55.1% lead. Data compression follows closely: 537785 vs 364399, a 47.6% margin. Random string sorting shows a 39.8% advantage (57177 vs 40885), and data encryption is 39% faster (29502 vs 21223). Floating-point math lands at 31.5% (105558 vs 80299), while integer math is 26.1% ahead (138932 vs 110195). These are not small gaps; they indicate a substantial throughput advantage in heavily parallel workloads.

In Cinebench, the story is consistent. R23 multi-core scores 34825 for the 12900KF versus 26861 for the 270H — a 29.6% lead. Single-core R23 is also 29.6% ahead (4916 vs 3792). The same margin repeats across R20 (14626 vs 11281 multi-core, 2064 vs 1592 single-core) and R15 (3510 vs 2707 multi-core, 495 vs 382 single-core). Even the 12900KF’s smallest win, Passmark physics, is 7.8% higher (2098 vs 1946). The only test the 270H wins is Passmark single-thread, where it scores 4404 against 4144 — a 5.9% advantage. That result appears twice in the data (as `passmark_single_thread` and `passmark_singlethread`), but it is a single test, and it does not offset the multi-threaded dominance.

FAQ

Q: Which CPU has the higher boost clock?

A: The Intel Core 9 270H boosts to 5.80 GHz, while the i9-12900KF reaches 5.20 GHz.

Q: Which CPU has more cores and threads?

A: The i9-12900KF has 16 cores and 24 threads; the 270H has 14 cores and 20 threads.

Q: Why does the 12900KF win most benchmarks but have a similar average score?

A: The average benchmark scores are nearly identical (42739 vs 42816), but the head-to-head data shows the 12900KF wins 15 of 17 tests. The 270H’s single Passmark single-thread lead is too small to overcome the 29.6% Cinebench multi-core gap.

Q: Which CPU has integrated graphics?

A: The 270H includes Iris Xe Graphics 96EU; the 12900KF has no integrated graphics.

Q: Which CPU is more power-efficient?

A: The 270H has a 45W TDP versus the 12900KF’s 125W TDP.

Q: Which CPU is newer?

A: The 270H was released on 2024-12-17, while the 12900KF launched on 2021-11-03.

The Verdict

The data is unambiguous: the i9-12900KF is the faster processor in nearly every measured workload. It leads by 29.6% in Cinebench R23 multi-core and single-core, and by 47.6% in data compression. If you are building a desktop system and need raw compute, the 12900KF is the clear choice. The 270H, however, has three distinct advantages: a higher boost clock (5.80 vs 5.20 GHz), a much lower TDP (45W vs 125W), and integrated graphics. It also wins the Passmark single-thread test by 5.9%. These features make the 270H the sensible option for a mobile platform or a system where power draw and portability matter more than peak multi-threaded performance. The two chips also target different sockets and market segments, so platform choice will often dictate the decision. But strictly from benchmark results, the 12900KF wins 15 of 17 head-to-head tests.

Architecture Differences

The 12900KF is built on Alder Lake, while the 270H uses Raptor Lake (specifically the Raptor Lake-H refresh). Both are fabricated on Intel’s 10 nm process, but the cache layouts differ. The 12900KF has 1.25 MB of L2 per core and 30 MB of shared L3; the 270H has 2 MB of L2 per core and 24 MB of shared L3. The L1 cache is identical at 80 KB per core. The 12900KF’s die size is 215 mm², while the 270H’s die size is not listed. The 270H integrates Iris Xe Graphics 96EU, whereas the 12900KF has no iGPU. PCIe connectivity also differs: the 12900KF provides 20 Gen 4 lanes from the CPU, while the 270H provides 8 Gen 5 lanes. The 12900KF uses an LGA 1700 socket and is desktop-oriented; the 270H uses BGA 1744 and is mobile-oriented. The 270H has an unlocked multiplier disabled (locked), while the 12900KF is unlocked.

Where Each One Wins

The i9-12900KF wins in every Cinebench test — R15, R20, and R23, both single and multi-core — with margins around 29.6%. It also wins all Passmark tests except single-thread: data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithread, physics, and random string sorting. For rendering, compression, encryption, or any heavily threaded workload, the 12900KF is the superior part.

The Intel Core 9 270H wins only the Passmark single-thread test, but it does so with a 5.9% margin (4404 vs 4144). Its higher boost clock (5.80 GHz) likely contributes to that result. Beyond raw performance, the 270H’s advantages are qualitative: a 45W TDP versus 125W, integrated graphics, and a mobile socket. For a thin-and-light laptop or a system where power efficiency and on-chip graphics are priorities, the 270H is the practical choice. For a desktop workstation or gaming rig where performance is the only metric that matters, the 12900KF’s 15 benchmark wins speak for themselves.
