The Verdict

The data supports a straightforward split. The Intel Core 9 273PQE is the stronger processor in every measured workload. Its 93rd percentile ranking against all CPUs, combined with an average benchmark score of 66099, places it in a different performance class than the i5-14400T, which sits at the 79th percentile with an average of 27166.

The Core 9 273PQE also holds up well against its own nearest rivals. It trails the Intel Core Ultra 5 250K Plus by 1.1% and the AMD EPYC 4465P by 1.2%, while edging the AMD Ryzen 9 7950X3D by 0.3% and essentially matching the Intel Core Ultra 5 250KF Plus at 0.1% behind. These numbers indicate that the Core 9 273PQE belongs to the upper tier of desktop processors in the database.

The i5-14400T, by contrast, competes in a lower performance band. Its nearest rivals include the older Intel Core i9-9900K and the AMD Ryzen 7 5700G, with deltas under 1%. This suggests the i5-14400T is a capable mid-range desktop part, but it does not approach the Core 9 273PQE in absolute performance.

The choice between the two depends on the workload requirements. For tasks that benefit from high multi-threaded throughput, math processing, or data compression, the Core 9 273PQE delivers roughly double the score of the i5-14400T. For lightly threaded tasks, the advantage narrows to 30.2%, which still favors the Core 9 273PQE.

Specification Differences

The two processors share several platform traits. Both use Intel Socket 1700, support DDR4 and DDR5 memory, run on a dual-channel memory bus, support ECC memory, and provide PCIe Gen 5 with 16 lanes from the CPU. Both are Intel parts on a 10 nm process node, and neither has an unlocked multiplier.

The differences are substantial. The Core 9 273PQE has 12 cores and 24 threads, while the i5-14400T has 10 cores and 16 threads. Base clock speeds differ sharply: 3.40 GHz for the Core 9 273PQE versus 1.50 GHz for the i5-14400T. Boost clocks reach 5.90 GHz on the Core 9 273PQE and 4.50 GHz on the i5-14400T. Thermal design power is 125 watts for the Core 9 273PQE and 35 watts for the i5-14400T.

Cache configurations also differ. The L1 cache is identical at 80 KB per core. The L2 cache is 2 MB per core on the Core 9 273PQE versus 1.25 MB per core on the i5-14400T. Shared L3 cache is 36 MB on the Core 9 273PQE and 20 MB on the i5-14400T. The i5-14400T has a listed die size of 215 mm², while no die size is recorded for the Core 9 273PQE.

Memory bandwidth is recorded only for the Core 9 273PQE at 89.6 GB/s. The i5-14400T has no memory bandwidth figure in the database. Integrated graphics differ as well: the Core 9 273PQE uses UHD Graphics 770, while the i5-14400T uses UHD Graphics 730. The release dates differ, with the i5-14400T launching in early 2024 and the Core 9 273PQE launching in early 2026.

Architecture Differences

The Core 9 273PQE uses the Bartlett Lake codename under the Core 9 generation label. The i5-14400T uses the Raptor Lake architecture with the Raptor Lake-R codename, belonging to the Core 14th Gen series and the Raptor Lake Refresh generation. Both are built on a 10 nm process at Intel's foundry.

The core count difference (12 versus 10) and thread count difference (24 versus 16) reflect distinct design targets. The Core 9 273PQE offers 36 MB of shared L3 cache against 20 MB on the i5-14400T. Per-core L2 also differs at 2 MB versus 1.25 MB. The larger cache pool on the Core 9 273PQE likely contributes to its strong showing in data compression and extended instructions, where the deltas reach 148.6% and 166.1% respectively.

Clock behavior reveals a notable architectural split. The i5-14400T has a low 1.50 GHz base clock with a 4.50 GHz boost, a wide range that suggests aggressive power management. The Core 9 273PQE starts at 3.40 GHz base and boosts to 5.90 GHz, a much higher floor and ceiling. The 125 watt TDP of the Core 9 273PQE versus 35 watts for the i5-14400T indicates the Core 9 273PQE is designed for sustained high output, while the i5-14400T targets efficiency.

The integrated graphics differ, with UHD Graphics 770 on the Core 9 273PQE and UHD Graphics 730 on the i5-14400T. Both support the same memory types and PCIe configuration. The i5-14400T has a recorded die size of 215 mm², which provides a physical reference for its silicon, while no equivalent figure exists for the Core 9 273PQE in the database.

Where Each One Wins

The Core 9 273PQE wins every recorded benchmark, so the use-case split is a matter of degree rather than direction. The largest advantages appear in compute-heavy and data-intensive workloads. Extended instructions show a 166.1% delta, prime number finding shows 171.2%, floating point math shows 155.5%, and integer math shows 150.7%. These results point to workloads such as scientific computing, financial modeling, and complex simulations as areas where the Core 9 273PQE offers roughly two and a half times the throughput.

Data compression and encryption also favor the Core 9 273PQE strongly, with deltas of 148.6% and 123.8%. Archiving, database operations, and secure data handling would benefit from the higher scores. The multithreaded tests, both in Cinebench and PassMark, show consistent 128% deltas, indicating that rendering, video encoding, and other parallel workloads would see roughly double the performance.

The i5-14400T is comparatively strongest in single-threaded work. The 30.2% delta in PassMark single-thread performance is the smallest gap in the entire comparison. Tasks that rely on single-core speed, such as basic office productivity, light web browsing, or older software that does not scale across cores, would see a smaller penalty when using the i5-14400T. The 35 watt TDP also indicates that the i5-14400T could fit into systems with limited cooling or power budgets, though the database does not record thermal or power measurements.

The i5-14400T also holds its own within its own performance class. Its nearest rivals, the Intel Core i9-9900K and AMD Ryzen 7 5700G, are within 0.4% of its average score. This places the i5-14400T in a competitive mid-range bracket where it trades blows with older high-end parts and modern mid-range offerings.

The Core 9 273PQE, by contrast, competes with the Intel Core Ultra 5 250KF Plus, AMD Ryzen 9 7950X3D, Intel Core Ultra 5 250K Plus, and AMD EPYC 4465P. The deltas among these four are all within 1.2%, which shows the Core 9 273PQE is positioned at the top of the desktop performance spectrum. Systems requiring maximum throughput in multi-threaded, math-heavy, or data-intensive tasks would find the Core 9 273PQE the appropriate choice. Systems where efficiency and lower power draw are priorities, and where the workload is primarily single-threaded, would see the i5-14400T as the more fitting part.
