Architecture Differences

The two processors share the same Intel Socket 1700 platform, which means they are drop-in compatible with the same motherboards. Both are built on Intel's 10 nm process node and are fabricated by Intel. However, the underlying designs diverge significantly.

The Core 9 273PTE comes from the Bartlett Lake family, a newer generation labeled "Core 9 (Bartlett Lake)". It uses a 12-core, 24-thread configuration, which suggests a hybrid design with a different core count allocation than the i5. The L2 cache is 2 MB per core, and the L3 cache is 36 MB shared, giving it a substantially larger total cache footprint. This chip also includes UHD Graphics 730 integrated graphics, which the i5-14400F lacks entirely.

The Core i5-14400F is part of the Core 14th Gen series, based on Raptor Lake-R architecture (codename Raptor Lake-R, generation "Core i5 (Raptor Lake Refresh)"). It has 10 cores and 16 threads, which is a classic performance-plus-efficient core hybrid layout. Its L2 cache is smaller at 1.25 MB per core, and the L3 cache is 20 MB shared. The die size is recorded at 215 mm², a figure not listed for the Bartlett Lake part. Both chips support DDR4 and DDR5 memory with dual-channel memory buses, and both expose Gen 5 PCIe with 16 CPU lanes.

Key architectural differences: the Core 9 has more cores and threads, a much larger L3 cache, and integrated graphics. The i5 has a higher base clock (2.50 GHz versus 1.40 GHz) and a smaller die size. Neither processor has an unlocked multiplier, so overclocking is not supported on either. The Core 9's release date is later (2026-03-08) compared to the i5 (2024-01-07). The memory bandwidth figure for the Core 9 is 89.6 GB/s, while the i5's memory bandwidth is not recorded in the database.

Head-to-Head Benchmarks

The head-to-head data shows a clear overall winner in the i5-14400F, which takes 14 of the 17 benchmark comparisons. The Core 9 273PTE wins only 3 tests.

Starting with the Cinebench suite, the i5-14400F wins every single test but by a narrow margin. In Cinebench R15 multicore, the i5 scores 2181 versus 2060 for the Core 9, a 5.5% advantage. The single-core R15 test shows the same 5.5% gap (307 versus 290). This pattern repeats across R20 and R23: multicore scores of 9090 versus 8586 and 21645 versus 20445 respectively, each with the same 5.5% delta. Single-core results follow: R20 at 1283 versus 1212, R23 at 3055 versus 2886. The consistency of this 5.5% gap across all Cinebench versions indicates a fundamental clock advantage for the i5 in both single-threaded and lightly threaded workloads.

PassMark results tell a mixed story. The i5 dominates in data compression (315521 versus 258704, an 18% lead) and data encryption (16949 versus 14253, a 15.9% lead). The biggest gap comes in extended instructions, where the i5 scores 19937 versus 15952, a full 20% advantage. Random string sorting also favors the i5 by 11.3% (32680 versus 28973). Floating point math is nearly identical, with the i5 ahead by only 1.1% (61319 versus 60673). The single-thread PassMark test shows the i5 at 3701 versus 3433, a 7.2% lead, and the multithread test shows 25470 versus 24054, a 5.6% lead.

The Core 9 273PTE wins three notable tests. Its biggest victory is in finding prime numbers, where it scores 142 versus 86, a massive 65.1% advantage. In physics simulation, the Core 9 leads with 1917 versus 1523, a 25.9% margin. The third win is in integer math, where it edges out the i5 by 1.1% (82411 versus 81524). The prime number result is particularly striking because it suggests the Core 9's architecture handles certain integer-heavy algorithms much more efficiently despite losing the overall multithread test.

Both share the same socket, process node, foundry, memory support (DDR4, DDR5), memory bus (dual-channel), ECC support, PCIe configuration (Gen 5, 16 lanes), market segment (desktop), production status (Active), and locked multiplier. The L1 cache is identical at 80 KB per core.

Where Each One Wins

The Core i5-14400F is the stronger performer in the majority of workloads. It wins all six Cinebench tests, which means it delivers better raw rendering performance in both single-threaded and multi-threaded scenarios. Its 5.5% lead in every Cinebench test shows a consistent clock-for-clock advantage. For content creation tasks like video encoding, 3D rendering, and photo editing that rely on these benchmarks, the i5 is the better choice.

The i5 also wins in data compression and encryption, making it preferable for file archiving, database workloads, and any task that involves heavy data throughput. Its 20% lead in extended instructions suggests better SIMD and vector processing capabilities, which benefits scientific computing, audio processing, and certain encryption algorithms. The single-thread and multithread PassMark scores confirm the i5's overall lead in general-purpose computing.

The Core 9 273PTE wins in three specific areas. The 65.1% lead in prime number finding indicates a significant advantage in certain integer-heavy algorithms, particularly those involving modular arithmetic or primality testing. This could translate to better performance in cryptography, number theory computations, or specific financial modeling tasks. The 25.9% win in physics simulation suggests stronger performance in physics engines used by games or simulation software. The narrow 1.1% win in integer math shows a slight edge in general integer operations.

The Core 9 also has advantages outside raw benchmarks: it includes integrated graphics (useful for troubleshooting or systems without a discrete GPU), a much larger L3 cache (36 MB versus 20 MB), and a lower TDP of 45 W versus 65 W. The lower TDP means it generates less heat and requires less aggressive cooling, which may be relevant for compact builds or systems with limited airflow.

The Verdict

The benchmark data clearly favors the Intel Core i5-14400F in overall performance. It wins 14 of 17 head-to-head comparisons, has a higher average benchmark score (32279 versus 31143), and sits at a higher percentile (83rd versus 82nd). The i5's consistent 5.5% lead across all Cinebench versions, combined with dominant wins in data compression, encryption, and extended instructions, makes it the stronger choice for most computing tasks.

The Core 9 273PTE does have specific strengths. Its 65.1% advantage in prime number finding and 25.9% lead in physics simulation are substantial, and its lower 45 W TDP makes it more efficient. The integrated graphics and larger L3 cache are practical benefits. However, these advantages apply to a narrower set of workloads.

For a general-purpose desktop CPU, the i5-14400F delivers better performance across the board in the recorded benchmarks. It also has a lower launch MSRP of $196 compared to $549 for the Core 9, though the database notes both are currently active products. The Core 9 273PTE makes sense only for users with specific workloads that match its three winning categories, or those who need integrated graphics and prioritize the lower power draw. For everyone else, the i5-14400F is the data-backed choice.
