Where Each One Wins

The Core i5-14400T is the clear winner in rendering workloads. The Cinebench R15, R20, and R23 multicore tests all show a 23.7% advantage, which translates to faster completion times for 3D rendering and video encoding tasks. The Passmark multithread test confirms this with a matching 23.7% gap.

Data-intensive workloads also favor the Core i5-14400T. The 50.8% lead in integer math and the 37.7% lead in data compression indicate that the Core i5-14400T handles database operations, file compression, and general arithmetic processing more efficiently. The 30% advantage in random string sorting further supports this pattern.

The Core 3 305 wins in the Passmark find prime numbers test by a large 57.5% margin. This suggests its architecture handles prime number calculations, which are common in cryptography and number theory applications, with notably better efficiency. The Core 3 305 also wins the Passmark single-thread test by 13.2%, indicating that for some single-threaded workloads it may deliver better responsiveness.

The physics test is effectively a tie, with the Core i5-14400T leading by only 0.9%. This means workloads that depend on physics calculations, such as certain simulation tasks, should perform nearly identically on both processors.

For users prioritizing multi-core throughput, rendering speed, and data processing, the Core i5-14400T is the superior choice based on the recorded benchmarks. For users with workloads centered on prime number finding or specific single-threaded applications where the Passmark result is representative, the Core 3 305 offers a measurable advantage.
