Intel Core 9 270H vs Intel Core i9-14901KE Comparison

The Verdict

The data presents a clear split between two very different Intel processors sharing the Raptor Lake architecture. The Intel Core 9 270H is a mobile part with 14 cores and 20 threads, built for laptops, while the Intel Core i9-14901KE is a desktop part with 8 cores and 16 threads. The Core 9 270H has a full benchmark suite recorded in the database, with an average score of 38335 and a percentile rank of 86 among all CPUs. The Core i9-14901KE has no recorded benchmark scores and an average score of 0, placing it at the 50th percentile by default. For any workload where measured performance matters, the Core 9 270H is the only option with data to analyze.

The Core 9 270H sits within 0.3% of several close rivals: it is 0.1% ahead of the Intel Core Ultra 9 285H, 0.2% ahead of the Intel Core i5-13600HX, and 0.3% ahead of the AMD Ryzen 7 250, while being 0.1% behind the Intel Xeon w3-2525. This places it in a tightly contested performance band. The Core i9-14901KE, lacking measurements, cannot be positioned against those rivals. The verdict: the Core 9 270H is the part with proven benchmark results, while the Core i9-14901KE remains an unmeasured desktop alternative with a higher core configuration on paper.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Intel Core 9 270H and the Intel Core i9-14901KE. The Core 9 270H has 17 recorded benchmark scores; the Core i9-14901KE has none. This absence of parallel data means no direct comparison of Cinebench or PassMark scores can be made from the recorded measurements.

The Core 9 270H's recorded scores provide a reference point. In Cinebench R23, it scores 18000 in multi-core and 2040 in single-core. In Cinebench R20, it scores 10268 multi-core and 1449 single-core. In Cinebench R15, it scores 2464 multi-core and 347 single-core. PassMark results include a multithread score of 28764, a single-thread score of 3944, integer math at 97654, floating point math at 70640, and extended instructions at 20079. Data compression reaches 333785, while data encryption is 19369. The Core i9-14901KE has no comparable entries, so the head-to-head comparison must rely on architectural and specification differences rather than measured performance.

Architecture Differences

Both processors use Intel's Raptor Lake architecture and are built on a 10 nm process at Intel's foundry. The Core 9 270H uses the Raptor Lake-H codename and belongs to the Core 9 generation (Raptor Lake Refresh). The Core i9-14901KE uses the Raptor Lake-R codename and belongs to the Core i9 generation (Raptor Lake Refresh). The die size differs: the Core i9-14901KE has a recorded die size of 257 mm², while the Core 9 270H has no die size recorded. Neither part has transistor counts or die size for the mobile chip in the database.

Cache organization is identical per core: both have 80 KB of L1 per core and 2 MB of L2 per core. The shared L3 cache differs substantially: the Core 9 270H has 24 MB shared, while the Core i9-14901KE has 36 MB shared. This gives the desktop part 12 MB more L3 cache despite having fewer cores. The mobile part compensates with more physical cores: 14 versus 8, and more threads: 20 versus 16. Both support DDR4 and DDR5 memory over a dual-channel bus, and neither has a recorded memory bandwidth figure.

The Core 9 270H uses an integrated Iris Xe Graphics 96EU, while the Core i9-14901KE uses UHD Graphics 770. PCIe connectivity differs: the mobile chip provides Gen 5 with 8 lanes (CPU only), while the desktop chip provides Gen 5 with 16 lanes (CPU only). ECC memory support is absent on the Core 9 270H and present on the Core i9-14901KE. The multiplier is locked on the mobile part and unlocked on the desktop part.

Specification Differences

The two processors diverge on nearly every specification field. Core counts: the Core 9 270H has 14 cores and 20 threads, the Core i9-14901KE has 8 cores and 16 threads. Base clocks: the mobile part runs at 2.70 GHz, the desktop part at 3.80 GHz. Boost clocks are identical at 5.80 GHz for both. TDP differs significantly: 45 W for the Core 9 270H versus 125 W for the Core i9-14901KE. The mobile part uses Intel BGA 1744, the desktop part uses Intel Socket 1700.

L3 cache favors the desktop part: 24 MB shared versus 36 MB shared. Die size is recorded only for the desktop part at 257 mm². Market segments differ: mobile versus desktop. Release dates differ: the Core 9 270H released on 2024-12-17, the Core i9-14901KE on 2024-06-30. The Core 9 270H has a launch MSRP of $697; the Core i9-14901KE has no launch MSRP recorded. The part numbers are SRQ6V for the mobile chip and Q49DSRNJC for the desktop chip. ECC support, integrated graphics model, PCIe lane count, and unlocked multiplier all differ as described above.

Where Each One Wins

The Intel Core 9 270H wins in measured performance categories. Its benchmark suite covers Cinebench R15, R20, and R23 in both multi-core and single-core tests, plus a full PassMark set. The data shows a single-thread PassMark score of 3944 and a multithread score of 28764. Its percentile rank of 86 places it above the majority of all CPUs in the database. The mobile part wins on core count, thread count, and power efficiency, with a 45 W TDP versus 125 W. It also carries a launch MSRP of $697, which can be stated once as a reference point.

The Intel Core i9-14901KE wins on specification advantages that have no measured performance backing. It has a higher base clock of 3.80 GHz versus 2.70 GHz, more L3 cache at 36 MB versus 24 MB, double the PCIe Gen 5 lanes at 16 versus 8, ECC memory support, an unlocked multiplier, and a larger die at 257 mm². It uses the desktop Socket 1700 instead of the mobile BGA 1744. The desktop part also has a lower percentile rank of 50 and an average benchmark score of 0, meaning the database contains no performance data to confirm those specification advantages in practice.

For workloads derived from the recorded benchmarks, the Core 9 270H delivers the only measurable results. The nearest rival data shows it is essentially tied with the Intel Core Ultra 9 285H at a 0.1% delta, the Intel Xeon w3-2525 at a -0.1% delta, the Intel Core i5-13600HX at a 0.2% delta, and the AMD Ryzen 7 250 at a 0.3% delta. These margins confirm that the Core 9 270H performs at the level of current mid-range and workstation-class chips. The Core i9-14901KE has no such positioning data, so any use-case advantage for it rests entirely on uncorroborated specifications like the higher base clock, larger L3 cache, ECC support, and extra PCIe lanes. The mobile chip wins every category with measured results; the desktop chip wins only the categories defined by its specification sheet.
