Intel Core 9 273PTE vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The benchmark database shows a clear overall winner: the Intel Core i5-14400 takes 14 of the 17 head-to-head comparisons, while the Intel Core 9 273PTE wins only 3. However, the margin of victory matters as much as the count, and the two processors win in very different ways.

The Core i5-14400 dominates the Cinebench suite. In Cinebench R15 multicore, it scores 2148 against 2060 for the Core 9 273PTE, a 4.1% advantage. The single-core R15 test shows 303 versus 290, a 4.3% lead. Moving to Cinebench R20, the i5-14400 posts 8952 multicore and 1263 single-core, while the Core 9 273PTE manages 8586 and 1212 respectively, both around 4% behind. Cinebench R23 follows the same pattern: 21315 versus 20445 in multicore and 3009 versus 2886 in single-core, again roughly 4.1% in favor of the i5-14400. This consistency across all three Cinebench versions indicates a steady, predictable performance gap in rendering workloads.

The PassMark suite shows a wider spread. The i5-14400 wins data compression by a substantial 17.9%, scoring 314995 against 258704. Data encryption shows a 14.8% gap, 16731 versus 14253. Extended instructions, which often reflects SIMD and AVX efficiency, favors the i5-14400 by 19.5%, the largest percentage margin in the entire comparison, with 19816 versus 15952. Random string sorting goes to the i5-14400 by 10.4%, 32346 versus 28973. Single-thread performance, measured by both passmark_single_thread and passmark_singlethread (identical scores of 3741 and 3433), gives the i5-14400 an 8.2% edge. Multithread overall favors the i5-14400 by 4.1%, 25080 versus 24054. Floating point math is nearly a tie, with the i5-14400 ahead by just 1.4%, 61549 versus 60673.

The Core 9 273PTE wins are narrow but specific. In find prime numbers, it scores 142 versus 80, a massive 77.5% advantage. This test often stresses integer-heavy, branch-dependent workloads, and the Core 9 273PTE delivers a decisive result. Integer math goes to the Core 9 273PTE by a slim 0.5%, 82411 versus 82017. Physics simulation gives the Core 9 273PTE a 37.3% win, 1917 versus 1396. These three wins suggest the Core 9 273PTE has particular strengths in certain computational patterns, even though it loses most other tests.

The average benchmark scores reflect this split: the i5-14400 averages 32115 across all recorded tests, while the Core 9 273PTE averages 31143, a difference of about 3%. Both processors sit at the 82nd percentile among all CPUs in the database, meaning they occupy the same overall performance tier despite the i5-14400's head-to-head advantage.

Architecture Differences

The two processors share the same Intel Socket 1700 platform and are both built on Intel's 10 nm process node. Both use a dual-channel memory bus and support DDR4 and DDR5 memory. Both also support ECC memory and offer PCIe Gen 5 with 16 lanes from the CPU. Neither has an unlocked multiplier, and both are classified as desktop parts with active production status.

The core configurations differ significantly. The Core 9 273PTE uses 12 cores and 24 threads, while the i5-14400 uses 10 cores and 16 threads. The Core 9 273PTE belongs to the Bartlett Lake codename family under the Core 9 generation, whereas the i5-14400 uses the Raptor Lake architecture, specifically Raptor Lake-R, and belongs to the Core 14th Gen series. The Core 9 273PTE has a die size that is not recorded in the database, while the i5-14400 has a die size of 215 mm².

Cache hierarchies also diverge. Both processors have 80 KB of L1 cache per core. The L2 cache differs: the Core 9 273PTE has 2 MB per core, while the i5-14400 has 1.25 MB per core. Total L3 cache shows a larger gap: the Core 9 273PTE has 36 MB shared, versus 20 MB shared for the i5-14400. This gives the Core 9 273PTE substantially more aggregate cache, which may explain its wins in cache-sensitive workloads like prime number finding and physics simulation.

The release timeline separates them by over two years. The Core 9 273PTE has a release date of March 2026, while the i5-14400 was released in January 2024. The i5-14400 carries part number SRN3QSRN46, and the Core 9 273PTE carries part number SA4QJ.

Specification Differences

The core and thread counts differ: 12 cores and 24 threads for the Core 9 273PTE against 10 cores and 16 threads for the i5-14400. Base clock speeds also differ, with the Core 9 273PTE running at 1.40 GHz and the i5-14400 at 2.50 GHz. Boost clocks go the other direction: the Core 9 273PTE reaches 5.50 GHz, while the i5-14400 tops out at 4.70 GHz.

Thermal design power shows a notable difference. The Core 9 273PTE has a TDP of 45 watts, while the i5-14400 has a TDP of 65 watts. This means the Core 9 273PTE is rated for lower power consumption despite having more cores and a higher boost clock.

The cache configuration differs as described above: L2 per core is 2 MB versus 1.25 MB, and L3 shared is 36 MB versus 20 MB. Memory bandwidth is listed only for the Core 9 273PTE at 89.6 GB/s, with no figure recorded for the i5-14400. The launch MSRP for the Core 9 273PTE is $549, and the launch MSRP for the i5-14400 is $221. Both use the same socket, same integrated graphics, same PCIe configuration, and same memory support.

Where Each One Wins

The Intel Core i5-14400 is the stronger choice for most general-purpose and creative workloads. Its Cinebench victories across all three versions indicate better rendering performance in both multicore and single-core scenarios. The 4.1% multicore advantage in R20 and R23, plus the 4.3% single-core edge in R15, suggests the i5-14400 delivers more consistent throughput for video encoding, 3D rendering, and photo editing tasks. The PassMark data compression win by 17.9% and encryption win by 14.8% point to advantages in file archiving, database operations, and security-related processing. The 19.5% lead in extended instructions further strengthens its position for scientific computing and multimedia codecs that use SIMD instructions. The 8.2% single-thread advantage makes it better for lightly threaded applications like web browsing, office productivity, and legacy software that relies on one or two cores.

The Intel Core 9 273PTE wins where its higher core count and larger cache pay off. The 77.5% margin in find prime numbers highlights a strong performance in integer-heavy, memory-latency-sensitive algorithms. The 37.3% win in physics simulation indicates an advantage in game physics calculations and certain engineering simulations. The narrow 0.5% integer math win, while small, shows the Core 9 273PTE can edge ahead in pure integer throughput. Its 12 cores and 24 threads, combined with 36 MB of L3 cache, give it a structural advantage in workloads that scale well with thread count and benefit from large on-chip data storage.

The power envelope also separates them. The Core 9 273PTE achieves its wins at a 45-watt TDP, while the i5-14400 operates at 65 watts. This means the Core 9 273PTE delivers its specific benchmark victories while rated for lower power draw, which can matter in compact desktop builds or systems with limited cooling capacity. The i5-14400, despite the higher TDP, wins more tests overall and holds a higher average benchmark score of 32115 versus 31143.

For users prioritizing rendering, compression, encryption, and single-thread responsiveness, the i5-14400 is the data-supported pick. For users running prime-number searches, physics simulations, or similarly cache-heavy integer workloads, the Core 9 273PTE shows clear advantages. The two processors occupy the same 82nd percentile tier, so the choice depends on workload mix rather than overall capability.
