Intel Core i9-14901KE vs Intel Core Ultra 7 258V Comparison

Head-to-Head Benchmarks

The Intel Core i9-14901KE has no recorded benchmark scores in the database, while the Intel Core Ultra 7 258V has a full suite of Cinebench, Geekbench, and Passmark results. Consequently, the head-to-head comparison is defined entirely by the Core Ultra 7 258V's measured performance, with no direct counter-scores from the Core i9-14901KE. The database shows the Core Ultra 7 258V holds a percentile rank of 74 among all CPUs, placing it above the median, while the Core i9-14901KE sits at the 50th percentile with an average benchmark score of zero.

The Core Ultra 7 258V's multi-core results show moderate throughput for an 8-thread part. In Cinebench R23, the recorded multi-core score is 10301, while the single-core score is 1872. The ratio between these two figures, roughly 5.5x, indicates that scaling from single-thread to multi-thread workloads is limited by the processor's 8 threads, which is expected given its thread count. In Geekbench, the multi-core score of 9325 and single-core score of 2100 show a similar pattern, with multi-core performance about 4.4x the single-core result.

Passmark results for the Core Ultra 7 258V provide more granular data. The multi-thread score is 18887, while the single-thread score is 4018. Floating point math scores 57372, which is notably higher than integer math at 42889, suggesting the architecture handles floating-point operations more efficiently. Data encryption scores 13534, and data compression scores 176686, a figure that far outstrips the encryption result and indicates strong throughput for compression workloads. Extended instructions score 14717, while finding prime numbers scores 185, and random string sorting scores 21580. Physics scores 1565, a relatively modest figure compared to the other Passmark subtests.

Architecture Differences

The Core i9-14901KE uses the Raptor Lake architecture, specifically the Raptor Lake-R codename, built on a 10 nm process node by Intel's own foundry. The Core Ultra 7 258V uses the Lunar Lake architecture with the same Lunar Lake codename, fabricated on a 3 nm process node by TSMC. This process difference is substantial: the 3 nm node is several generations ahead of the 10 nm node, allowing for denser transistors and lower power draw per transistor, though the Core i9-14901KE compensates with a larger die size of 257 mm², while the Core Ultra 7 258V has no recorded die size.

Both processors have 8 cores, but the threading models differ. The Core i9-14901KE supports 16 threads, meaning each core can handle two threads simultaneously. The Core Ultra 7 258V supports 8 threads, meaning each core handles exactly one thread. This gives the Core i9-14901KE a 2x thread count advantage, which directly impacts multi-threaded workloads that can utilize more than 8 threads.

Cache hierarchies diverge significantly. 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 258V has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 12 MB of shared L3 cache. The Core Ultra 7 258V has larger per-core L1 and L2 caches, but the Core i9-14901KE has 3x the L3 cache, which can benefit workloads with large working sets that fit within the shared cache.

Integrated graphics differ as well. The Core i9-14901KE includes UHD Graphics 770, while the Core Ultra 7 258V includes Arc 140V. The Arc 140V represents a newer graphics architecture with more execution resources, though the database does not provide comparative graphics benchmark scores.

The Core i9-14901KE is a desktop part with an unlocked multiplier, while the Core Ultra 7 258V is a mobile part with a locked multiplier. The Core i9-14901KE supports ECC memory, while the Core Ultra 7 258V does not. Memory support also differs: the Core i9-14901KE supports DDR4 and DDR5, while the Core Ultra 7 258V supports LPDDR5X only.

The Verdict

The database shows two processors with divergent design goals. The Intel Core i9-14901KE is a desktop-class, high-power part with 16 threads, a 125 W TDP, a 5.80 GHz boost clock, and 36 MB of L3 cache. It targets workloads that can utilize many threads and sustained high clock speeds, such as multi-threaded rendering, compilation, and content creation. Its unlocked multiplier and ECC memory support position it for enthusiast and workstation use cases.

The Intel Core Ultra 7 258V is a mobile-class, low-power part with 8 threads, a 17 W TDP, a 4.80 GHz boost clock, and 12 MB of L3 cache. Its measured benchmarks place it at the 74th percentile, with an average score of 20454 that sits within 0.4% of four AMD rivals. The data indicates it delivers competitive performance for its power envelope, particularly in single-threaded and lightly threaded tasks, as shown by its Cinebench R23 single-core score of 1872 and Geekbench single-core score of 2100.

For buyers choosing between the two, the decision hinges on platform and power constraints. The Core i9-14901KE offers double the thread count and a larger L3 cache, which should deliver substantially higher multi-threaded throughput, though no benchmark scores confirm this. The Core Ultra 7 258V offers verified performance data, a much lower power draw, and a newer process node, making it suitable for mobile systems where battery life and thermals are priorities. The Core i9-14901KE requires a Socket 1700 motherboard and supports DDR4 or DDR5 memory, while the Core Ultra 7 258V uses BGA 2833 and requires LPDDR5X. The data does not support a single winner; it supports two different usage profiles. The Core i9-14901KE is the choice for desktop users seeking maximum multi-threading capability, while the Core Ultra 7 258V is the choice for mobile users who need measured, efficient performance in a compact package.
