Since the Core i9-14901KE has no recorded benchmark scores, its percentile rank of 50 and average benchmark score of 0 in the database reflect a lack of measurement data rather than actual performance. The head-to-head wins stand at zero for both processors, confirming no direct comparisons exist.

Architecture Differences

The two processors represent fundamentally different design approaches from Intel. The Core i9-14901KE uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process node. The Core Ultra 7 366H uses the Panther Lake architecture, built on a 3 nm process node. This process node difference is substantial: the 3 nm node allows for significantly denser transistor packing and improved power efficiency compared to the 10 nm node.

The Core i9-14901KE features 8 cores and 16 threads, while the Core Ultra 7 366H features 16 cores and 16 threads. This means the Core Ultra 7 366H has twice the core count but the same thread count, indicating a different core topology. The Core i9-14901KE likely uses hyper-threading on its 8 physical cores to reach 16 threads, while the Core Ultra 7 366H achieves 16 threads from 16 physical cores, possibly with a mix of performance and efficiency cores.

Cache hierarchies differ markedly. The Core i9-14901KE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 7 366H has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and only 18 MB of shared L3 cache. The Core i9-14901KE offers double the L3 cache, which can benefit workloads with large working sets, while the Core Ultra 7 366H provides more L1 and L2 cache per core.

The die size for the Core i9-14901KE is 257 mm², while the Core Ultra 7 366H has no recorded die size. The Core i9-14901KE is a desktop processor on Intel Socket 1700, while the Core Ultra 7 366H is a mobile processor on Intel BGA 2540. This form factor difference influences thermal and power characteristics.

Clock speeds diverge sharply. The Core i9-14901KE has a base clock of 3.80 GHz and a boost clock of 5.80 GHz. The Core Ultra 7 366H has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The Core i9-14901KE's higher clocks, especially the 5.80 GHz boost, likely provide superior single-threaded performance, while the Core Ultra 7 366H's 16 cores may compensate in multi-threaded workloads.

Memory support differs: the Core i9-14901KE supports DDR4 and DDR5, while the Core Ultra 7 366H supports DDR5 and LPDDR5X. The Core Ultra 7 366H records a memory bandwidth of 115.2 GB/s, while the Core i9-14901KE has no recorded memory bandwidth. Both use dual-channel memory buses. The Core i9-14901KE supports ECC memory, while the Core Ultra 7 366H does not.

PCIe lanes also differ: the Core i9-14901KE provides Gen 5 with 16 lanes (CPU only), while the Core Ultra 7 366H provides Gen 5 with 12 lanes (CPU only). Integrated graphics differ as well: the Core i9-14901KE uses UHD Graphics 770, while the Core Ultra 7 366H uses Intel Xe3 Graphics.

The Verdict

The data indicates two processors optimized for different environments. The Core i9-14901KE is a desktop processor with a 125 W TDP, a 5.80 GHz boost clock, and 36 MB of L3 cache, designed for high-performance desktop workloads. The Core Ultra 7 366H is a mobile processor with a 25 W TDP, a 4.80 GHz boost clock, and 18 MB of L3 cache, designed for power-efficient mobile computing.

The Core Ultra 7 366H has recorded benchmark scores placing it at the 87th percentile, while the Core i9-14901KE has no recorded benchmarks. This does not mean the Core i9-14901KE is slower; it means the database lacks measurement data for it. The Core Ultra 7 366H's 16 cores versus the Core i9-14901KE's 8 cores suggests a multi-threaded advantage for the mobile chip, but the Core i9-14901KE's higher clock speeds and larger L3 cache suggest a single-threaded and cache-sensitive advantage.

The production status for both is Active, with release dates of 2024-06-30 for the Core i9-14901KE and 2026-01-04 for the Core Ultra 7 366H. The Core i9-14901KE has an unlocked multiplier, while the Core Ultra 7 366H does not, indicating overclocking support for the desktop part.

For desktop users requiring high single-thread performance and overclocking, the Core i9-14901KE is the clear choice based on its specifications. For mobile users needing multi-core performance in a low-power envelope, the Core Ultra 7 366H is the appropriate selection. The benchmark data confirms the Core Ultra 7 366H delivers competitive performance within its class, but the absence of Core i9-14901KE benchmarks prevents a definitive performance comparison.
