Intel Core i5-14401E vs Intel Core Ultra 5 245KF Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core Ultra 5 245KF outperforms the Intel Core i5-14401E in every recorded test. The Core Ultra 5 245KF wins all six head-to-head benchmark comparisons, with a 100% win rate in the database. The i5-14401E records zero wins. The Core Ultra 5 245KF sits at the 91st percentile among all CPUs, while the i5-14401E sits at the 60th percentile. The Ultra 5 delivers roughly double the performance in both multi-core and single-core Cinebench workloads. The Core Ultra 5 245KF is the clear choice for users who prioritize raw compute throughput, especially in threaded workloads. The i5-14401E remains a functional desktop processor, but the data does not show any scenario where it leads.

However, the i5-14401E does have attributes that matter outside pure benchmark scores. It supports DDR4 memory, includes integrated graphics (UHD Graphics 730), and has a 65 TDP. The Core Ultra 5 245KF has no integrated graphics, supports only DDR5, and has a 125 TDP. Users who need a fallback display output without a discrete GPU, or who want to reuse DDR4 memory, may find the i5-14401E more practical despite its lower scores. The Core Ultra 5 245KF also carries a launch MSRP of $294. The i5-14401E has no recorded launch MSRP in the database.

Architecture Differences

The two processors come from fundamentally different Intel generations. The i5-14401E uses Raptor Lake, specifically the Raptor Lake-R refresh, built on Intel's 10 nm process node. The Core Ultra 5 245KF uses Arrow Lake, the Arrow Lake-S variant, built on TSMC's 3 nm process node. The process node difference explains much of the performance gap: the Ultra 5 uses a smaller, more advanced manufacturing process.

The transistor counts differ substantially. The Core Ultra 5 245KF packs 17,800 million transistors on a 243 mm² die. The i5-14401E does not have a transistor count recorded in the database, but its die size is 215 mm². The Ultra 5 crams more transistors into a slightly larger die, which aligns with its higher core count and cache capacity.

Cache hierarchies differ as well. The i5-14401E has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. The Core Ultra 5 245KF has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The Ultra 5 has more cache at every level, which contributes to its higher single-thread and multi-thread performance in the recorded benchmarks.

Memory support diverges sharply. The i5-14401E supports both DDR4 and DDR5, with dual-channel memory bus. The Core Ultra 5 245KF supports only DDR5, also dual-channel, but with a recorded memory bandwidth of 102.4 GB/s. The i5-14401E has no memory bandwidth figure in the database. The Ultra 5 also supports ECC memory, while the i5-14401E does not. PCIe connectivity differs: the i5-14401E provides Gen 5 with 16 lanes (CPU only), while the Core Ultra 5 245KF provides Gen 5 with 20 lanes (CPU only).

The socket types are incompatible. The i5-14401E uses Intel Socket 1700, while the Core Ultra 5 245KF uses Intel Socket 1851. This means motherboard choice is exclusive to each processor. The Core Ultra 5 245KF has an unlocked multiplier, while the i5-14401E does not, making the Ultra 5 more flexible for overclocking scenarios.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern: the Core Ultra 5 245KF roughly doubles the i5-14401E's scores across all six tests. In Cinebench R15 multi-core, the Ultra 5 scores 3693 versus 1830 for the i5-14401E, a delta of 50.4% in favor of the Ultra 5. In Cinebench R15 single-core, the Ultra 5 scores 521 versus 258, a 50.5% delta. The pattern repeats in R20: multi-core 15391 versus 7627 (50.4% delta), single-core 2172 versus 1076 (50.5% delta). In R23, the multi-core scores are 36647 versus 18161 (50.4% delta), and single-core scores are 5173 versus 2564 (50.4% delta).

The deltas are nearly identical across all Cinebench versions, which indicates the performance gap is structural rather than workload-specific. The Ultra 5 benefits from more cores (14 versus 6), more threads (14 versus 12), higher base and boost clocks (4.20 GHz and 5.20 GHz versus 2.50 GHz and 4.70 GHz), and a larger cache. The i5-14401E has 12 threads from 6 cores, meaning it relies on hyperthreading. The Ultra 5 has 14 threads from 14 cores, which means no hyperthreading but a larger physical core count.

The database also includes PassMark results for the Core Ultra 5 245KF, which are not recorded for the i5-14401E. The Ultra 5 scores 43110 in PassMark multi-thread, 4715 in single-thread, 131546 in floating point math, 98854 in integer math, 460123 in data compression, 33381 in data encryption, 37912 in extended instructions, 416 in find prime numbers, 2998 in physics, and 55206 in random string sorting. These figures provide context for the Ultra 5's overall average benchmark score of 55093, compared to the i5-14401E's average of 5253.

Where Each One Wins

The Core Ultra 5 245KF wins every recorded benchmark comparison. In Cinebench R15, R20, and R23, it leads by roughly 50% in both multi-core and single-core tests. This is the dominant performance profile. The Ultra 5's advantages come from its 14 cores, higher clock speeds (4.20 GHz base, 5.20 GHz boost), larger caches, and 3 nm TSMC process node. It also has a higher average benchmark score (55093) and a higher percentile ranking (91st). The Ultra 5 is the appropriate choice for compute-heavy workloads, including multi-threaded rendering, data compression, encryption, and physics simulations, based on the recorded PassMark results.

The i5-14401E does not win any benchmark, but it has practical strengths. It supports DDR4 memory, which allows users to reuse existing memory modules. It includes integrated graphics, which provides a display output without a discrete GPU. Its 65 TDP indicates lower power consumption compared to the Ultra 5's 125 TDP. The i5-14401E also supports ECC memory, which is absent on the Ultra 5. For users who need ECC memory or integrated graphics, or who prefer DDR4 compatibility, the i5-14401E offers a viable alternative despite its lower scores.
