Intel Core i5-14401TE vs Intel Core Ultra 5 245K Comparison

Head-to-Head Benchmarks

The benchmark database contains no recorded measurements for the Intel Core i5-14401TE. Its average benchmark score is listed as 0, and it holds a 50th percentile position among all CPUs. The Intel Core Ultra 5 245K, by contrast, has a full set of recorded benchmark scores, an average benchmark score of 54053, and sits in the 91st percentile. This means the Core Ultra 5 245K has a significant measurable performance advantage, while the Core i5-14401TE has no empirical scores to compare.

For the Core Ultra 5 245K, the Cinebench results show a strong multi-core showing. In Cinebench R15 multi-core, it scores 3850 points, while its single-core score is 322. The R20 run delivers 15368 multi-core and 2169 single-core. The R23 test produces 25066 multi-core and 2132 single-core. These numbers indicate that the Core Ultra 5 245K scales well across multiple threads, with the multi-core scores being roughly 12 times higher than single-core in R20 and R23, and about 12 times in R15 as well. That scaling pattern is typical of a processor with many physical cores and no hyper-threading, which the Core Ultra 5 245K has with 14 cores and 14 threads.

The PassMark suite adds more detail for the Core Ultra 5 245K. Data compression reaches 458817, data encryption reaches 33286, and extended instructions reach 37617. Floating point math scores 130678, integer math scores 98524, and find prime numbers scores 414. Random string sorting scores 55098. The multi-thread PassMark score is 43047, while the single-thread score is 4714. The ratio between multi-thread and single-thread here is about 9.1 times, which is consistent with a processor that has many cores but limited thread duplication.

Because the Core i5-14401TE has no benchmark entries, the head-to-head comparison is one-sided. The database records zero wins for the Core i5-14401TE and zero wins for the Core Ultra 5 245K in the head-to-head array, but that array is empty. The practical interpretation is that any performance comparison must rely on the Core Ultra 5 245K's measured scores and the architectural differences between the two processors. The Core i5-14401TE's 6 cores and 12 threads suggest it would produce lower multi-core scores than the Core Ultra 5 245K's 14 cores and 14 threads, but no direct measurement exists to confirm that.

The nearest rivals for the Core Ultra 5 245K provide context for its score. The Intel Xeon 6505P averages 53701, which is 0.7% lower. The Intel Core i7-14700F averages 53620, 0.8% lower. The Intel Xeon Phi 7290 averages 53469, 1.1% lower. On the other side, the AMD Ryzen 9 9900X3D averages 54762, which is 1.3% higher than the Core Ultra 5 245K. These small deltas indicate the Core Ultra 5 245K sits in a tightly contested performance band, with rivals within roughly one percentage point in either direction.

The Verdict

The data clearly favors the Intel Core Ultra 5 245K for any workload that benefits from multi-core processing. Its recorded scores across Cinebench R15, R20, R23, and PassMark demonstrate robust throughput, and its 91st percentile ranking places it well above the Core i5-14401TE's 50th percentile. The Core i5-14401TE has no benchmark scores in the database, so there is no measured evidence of its performance. Any selection between these two processors should be based on the architectural and specification differences, because the benchmark record is incomplete for one side.

The Core Ultra 5 245K also has a higher boost clock of 5.20 GHz compared to 4.50 GHz for the Core i5-14401TE, and a higher base clock of 4.20 GHz versus 2.00 GHz. These clock advantages, combined with the larger core count, make the Core Ultra 5 245K the stronger choice for sustained throughput. The Core i5-14401TE does have a lower TDP of 45 watts versus 125 watts, which could appeal to systems with thermal or power constraints, but the performance record does not support it as a faster option.

For users who need single-thread performance, the Core Ultra 5 245K again leads based on its measured single-core scores. The R23 single-core score of 2132 and PassMark single-thread score of 4714 are solid numbers. The Core i5-14401TE has no such measurements, so its single-thread capability cannot be quantified from the database. The verdict is straightforward: the Core Ultra 5 245K is the performance pick, while the Core i5-14401TE offers a lower-power alternative with fewer cores.

Where Each One Wins

The Intel Core Ultra 5 245K wins on every measurable performance front. Its Cinebench R23 multi-core score of 25066 and single-core score of 2132 are recorded, while the Core i5-14401TE has no scores. The PassMark multi-thread score of 43047 and single-thread score of 4714 further establish the Core Ultra 5 245K as the stronger processor for both threaded and single-threaded workloads. Its higher boost clock of 5.20 GHz, larger cache hierarchy, and 14 cores make it the clear choice for compute-heavy tasks such as rendering, encoding, and compilation.

The Core i5-14401TE wins on power efficiency and platform flexibility. Its 45 watt TDP is less than half of the Core Ultra 5 245K's 125 watt TDP, making it suitable for systems where heat and power draw are limiting factors. It also supports DDR4 memory in addition to DDR5, which allows for lower-cost memory configurations or reuse of existing DDR4 modules. The Core i5-14401TE uses the Intel Socket 1700 platform, which is an older socket, while the Core Ultra 5 245K uses Intel Socket 1851. For users with an existing Socket 1700 motherboard, the Core i5-14401TE could be a drop-in upgrade, whereas the Core Ultra 5 245K requires a new motherboard.

The Core Ultra 5 245K also wins on memory bandwidth, with a recorded 102.4 GB/s, and on PCIe lane count, with 20 Gen 5 lanes versus 16 Gen 5 lanes. Its unlocked multiplier allows overclocking, while the Core i5-14401TE has a locked multiplier. The integrated graphics on the Core Ultra 5 245K, Arc Xe-LPG Graphics 64EU, are a newer architecture than the UHD Graphics 730 on the Core i5-14401TE, which may provide better graphics performance for light gaming or media tasks.

In summary, the Core Ultra 5 245K is the performance leader across all benchmark categories with recorded data. The Core i5-14401TE offers a lower-power, DDR4-compatible alternative with a smaller core count, but its performance cannot be verified from the database because no benchmark scores are recorded for it. The choice between the two comes down to whether the priority is maximum measured performance or lower power draw and memory flexibility.
