Intel Core 9 273PTE vs Intel Core i5-14401E Comparison

Head-to-Head Benchmarks

The Intel Core 9 273PTE wins every recorded head-to-head benchmark against the Intel Core i5-14401E, with a consistent margin across both single-threaded and multi-threaded workloads. The largest edge appears in Cinebench R15 multi-core, where the Core 9 273PTE scores 2060 against 1830 for the i5-14401E, a 12.6% advantage. That same 12.6% delta repeats in Cinebench R20 multi-core (8586 vs 7627) and Cinebench R23 multi-core (20445 vs 18161). The pattern is remarkably uniform: every multi-core Cinebench result shows the Core 9 273PTE ahead by exactly 12.6%.

Single-core results tell a similar story, though the margins are slightly tighter. In Cinebench R15 single-core, the Core 9 273PTE scores 290 against 258, a 12.4% lead. Cinebench R20 single-core shows 1212 vs 1076, again a 12.6% delta, and Cinebench R23 single-core delivers 2886 vs 2564, also 12.6%. The near-identical percentage across all six tests indicates that the performance gap is structural rather than workload-specific.

The Core 9 273PTE also holds a commanding position in the broader database. Its average benchmark score is 31143, placing it in the 82nd percentile among all CPUs. Its nearest rivals include the Intel Core i7-12700F (average score 31081, a 0.2% delta) and the AMD Ryzen 9 8945HS (31074, also 0.2% delta). The Core 9 273PTE sits essentially level with those parts, edging them by fractions of a percent.

The i5-14401E, by contrast, has an average benchmark score of 5253 and sits in the 60th percentile. Its nearest rivals are the Intel Xeon E5-2699A v4 (5259, a -0.1% delta), the Intel Core i7-11700B (5241, 0.2% delta), and the Intel Core i9-10850K (5240, 0.2% delta). The gap between these two processors in average score is enormous: 31143 versus 5253, a difference of roughly sixfold. That gap reflects not only the Core 9 273PTE's superior Cinebench results but also its additional PassMark scores, which the i5-14401E lacks entirely in the recorded data.

Architecture Differences

The two processors share a socket, a process node, and an integrated GPU, but their internal designs diverge sharply. Both use Intel Socket 1700 and are built on Intel's 10 nm process. Both support DDR4 and DDR5 memory in dual-channel configuration, and both include UHD Graphics 730. Both also expose PCIe Gen 5 with 16 CPU lanes, and both support ECC memory.

The Core 9 273PTE is a Bartlett Lake part, released in March 2026, while the i5-14401E belongs to the Raptor Lake Refresh family, released in June 2024. The Core 9 273PTE is not assigned to a numbered series in the database, whereas the i5-14401E is explicitly listed as Core 14th Gen. The architecture field for the Core 9 273PTE is blank, but its codename identifies it as Bartlett Lake. The i5-14401E is listed with the Raptor Lake architecture and the Raptor Lake-R codename.

Core counts differ substantially. The Core 9 273PTE has 12 cores and 24 threads, while the i5-14401E has 6 cores and 12 threads. That is a direct doubling of both physical and logical cores. The cache hierarchy reflects this: both have 80 KB of L1 per core, but the Core 9 273PTE carries 2 MB of L2 per core versus 1.25 MB per core for the i5-14401E. Shared L3 is also larger on the Core 9 273PTE: 36 MB versus 20 MB.

Clock speeds present a mixed picture. The i5-14401E has a higher base clock at 2.50 GHz versus 1.40 GHz for the Core 9 273PTE. But the Core 9 273PTE boosts much higher, reaching 5.50 GHz versus 4.70 GHz for the i5-14401E. The Core 9 273PTE also has a lower TDP at 45 watts versus 65 watts for the i5-14401E, despite having twice the cores and a higher boost frequency.

The die size is recorded only for the i5-14401E at 215 mm². The Core 9 273PTE has no die size figure in the database. Neither processor has a recorded transistor count. Both are locked parts (multiplier unlocked is false for both).

Where Each One Wins

The Core 9 273PTE wins every benchmark category in the head-to-head data. Its multi-core advantage is consistent at 12.6% across Cinebench R15, R20, and R23. That makes it the clear choice for workloads that scale with thread count, such as rendering, compilation, or scientific computing. The doubling of cores and threads from 6/12 to 12/24, combined with the larger L2 and L3 caches, explains why the multi-core margin is so stable.

The single-core results also favor the Core 9 273PTE, with a 12.4% to 12.6% lead depending on the Cinebench version. The higher boost clock of 5.50 GHz versus 4.70 GHz gives it an edge in lightly threaded applications. The Core 9 273PTE also holds a wide advantage in the PassMark suite, though the i5-14401E has no recorded PassMark scores to compare directly. The Core 9 273PTE's PassMark single-thread score is 3433, its multithread score is 24054, and its integer math score is 82411. These figures place it in the 82nd percentile overall.

The i5-14401E has no benchmark wins in the head-to-head comparison. Its only potential advantage lies in its higher base clock of 2.50 GHz, which could translate to better sustained performance in short bursts at lower power states, but the recorded data shows no workload where it outperforms the Core 9 273PTE. The i5-14401E does have a lower average benchmark score relative to its nearest rivals, sitting at 5253 with a -0.1% delta against the Xeon E5-2699A v4, meaning it is essentially tied with that part.

The Verdict

The data is unambiguous. The Intel Core 9 273PTE outperforms the Intel Core i5-14401E in every recorded benchmark, with a consistent 12.6% margin in multi-core and single-core Cinebench tests. The Core 9 273PTE doubles the core and thread count, carries more L2 and L3 cache, boosts higher, and does so at a lower TDP of 45 watts versus 65 watts.

The Core 9 273PTE's average benchmark score of 31143 places it in the 82nd percentile, level with parts like the Intel Core i7-12700F and AMD Ryzen 9 8945HS. The i5-14401E's average score of 5253 places it in the 60th percentile, roughly matching the Intel Core i9-10850K and Intel Core i7-11700B. The Core 9 273PTE is not merely faster; it occupies a different performance tier entirely.

The i5-14401E does have a higher base clock and a smaller die size (215 mm²), but these factors do not translate into any benchmark victory. The Core 9 273PTE also has a recorded memory bandwidth of 89.6 GB/s, while the i5-14401E has no figure in the database. The Core 9 273PTE carries a launch MSRP of $549, while the i5-14401E has no recorded launch price.

For anyone choosing between these two on the basis of the recorded measurements, the Core 9 273PTE is the superior processor in every tested dimension. The i5-14401E may appeal to systems where a lower core count and higher base clock are sufficient, but the benchmark data does not identify a single workload where it wins. The verdict is clear: the Core 9 273PTE dominates this comparison.
